ADVANCE NEWS )F THE EXHIBITS

at the Commere al Motor Show

New Trailing-axle Rigid Six-wheeler, New 5-tonner All Engine Powers Increased 11HE new Mandator high-speed 6-tonner is, except for the Regal Four single-decker chassis, the only new model :hat will not be shown either on the company's stand or in he collective chassis exhibit in the Empire Hall.

The new Matador four-cylinder 5-tonner, which has the .mproved engine, giving about 80 b.h.p., will be seen as a stripped chassis on stand 133. This has a wheelbase 2 ft. 3 ins, longer than that of the Monarch 4-tonner, so that a platform space 17 ft. 6 ins, long is available.

The Mercury normal-control, four-cylinder, 65 b.h.p. 4-tortner will also be seen in chassis form on stand 133. rhis has an overhead-worm final drive and will be remembered as the chassis that was originally sold for 3k-ton loads.

A complete bus of familiar corporation type is the Regent double-saloon 56-seater with body by the Brush Electrical Engineering Co., Ltd., and beside it on stand 59 will be two examples of the Regal Six, one with a coach body and the other shown as a service bus. Both are 32-seaters. These and the double-decker have the company's six-cylindered petrol engine, the power of which has, by induction improve-. meats, been increased to 120 b.h.p.

A chassis which is reckoned by many to represent the municipal type of the future will be displayed in the Renown oil-engined six-wheeler with double-deck body seating 60 to 65 persons. About 500 of this type, mostly with petrol engines, are used in London, the feature being that the wide frame, single rear tyres and long single springs give comfort :with lateral stability.

A goods-carrying rigid six-wheeler with trailing axle, intended for main-road work with a 12-ton load, is the new Mammoth Major, and it is intended to place upon this vehicle's large platform body an example of the company's improved six-cylindered oil engine. In its latest form this unit develops 130 b.h.p. at 3,000 r.p.m., and it weighs 1,414 lb. Visitors should compare it with the sectioned 120 b.h.p. petrol engine which will be shown working.

ALBION Stand 38 A Complete Range of Passenger and Goods Models to be Exhibited for the First Time at Olympia

EXCEPTIONAL interest will undoubtedly be displayed In the products of Albion Motors, Ltd., not only because the company is one of the oldest in the industry, but also for the reason that whilst certain of the machines to be

D32 shown have been on the market for some time, not one has appeared previously at Olympia and two of them" are absolutely new. Amongst the passenger models there will be the new Albion Valiant six-cylinder 32seater bus, with a front-entrance body built 'by W. Alexander and Sons, Ltd., of Falkirk. This is a high-speed model with inclined overhead valves operated by a high camshaft, whilst condensation of steam inside the engine is overcome by situating breathers at the highest points of the timing-gear easing and valve-rocker covers. This model was recently described in full in this journal. Next, there will be the Albion Victor 20seater, which is a low-built machine with four-wheel braking specially designed for country service. It has a four-cylindered engine and may be considered as a big bus scaled down. The body sits three abreast instead of four, thus avoiding a dumpy appearance.

There will be a very wide range of goods models, the largest being the forward-control as highly finished chassis. The latter is sturdily built and weighs only 2 tons 18i cwt. It is also available with forward controL The four-cylindered engine is rated Jet 30-55 h.p. and is a side-valve unit notable tor Its accessibility and ease of maintenance. The clutch, gearbox and back axle follow standard Albion practice. The foot brake is operated through a servo, and on this model, as on the other Albions, the brake facings can be renewed without disturbing the hub bearings.

The high-speed 40-45-cwt. model has the engine and gearbox as a neat unit, and a low, strong frame with room for a body frame 10 ft. 9 ins. long. It weighs approximately 1 ton 17i cwt., so that even with a stoutly built body the vehicle can still qualify for the legal speed of 30 m.p.h.

The 5-tonner will he shown as a bonnettype lorry, although here again a forwardcontrol model is available. . The 0-tanner is an impressive machine with a well-built driver's cab constructed over the engine. With a body 16 ft. 6 ins, long the wheelbase is only 12 ft. 2 ins.

Five Albions will be found on bodybuilders' stands. '

ARMSTRONG-SAURER Stand 26

Four-wheeled 6-tonners and Six-wheeled 12-tonners Obtainable with Petrol or Oil Engines.

THE arrangement for the manufacture of Saurer chassis in this country under the name Armstrong-Saurer is one of first importance. For convenience, the company's range of oil-engined chassis is known by names beginning with D. and the petrol-engined models by names beginning with P. Briefly, in both ranges there are 6-tonners with four-cylindered and six-cylindered engines, and 12-ton rigid sixwheelers with six-cylindered engines. Only the oil-engined machines are being displayed at Olympia.

The Defiant 6-tonner has a four-cylindered, 52 b.h.p. engine, 14-ft. 9-in, wheelbase and 40-in. by 8-in, pneumatic tyres (twin rear). With a trailer it handles 10-12 tons. The Dauntless six-cylinder, 80 b.h.p. chassis will carry G tons, or, with a trailer, 12 tons. This has a wheelbase of 16 ft., and a feature is that Armstrong-Saurer wheels designed for use with the Goodyear K-type rims are fitted as standard. Another example of the• Dauntless, -which corresponds to the oleil Saurer 6BLD type, will be seen as a polished chassis, witil a wheelbase of 16 ft. 4 ins. The Dominant rigid six-wheeled, oil-engined chassis for 12-ton loads will also be seen. This has the same type of 80 b.h.p. engine as fitted in the Dauntless, and the wheelbase is 17 ft. 8 ins. Both this and the Dauntless have double-reduction final drive.

AUSTIN Stand 41 New "Twelve-Six" and 7 h.p. Vans, Together with Modified 12 h.p. and 20 h.p. Ambulances

THE Austin vehicles to be exhibited include vans, ambulances and taxicabs. Two new models will be shown for the first time, one taking the form of a 7-10-cwt. van having as its basis the company's 13.9 h.p. six-cylinder chassis, whilst the other is a modified 7 h.p. van. Built specifically to cater for operators who require a fast, light delivery van....:4with a good loading space, the new Twelve-Six is a vehicle constructed on well-established lines. 1)33

The six-cylindered side-valve engine, rated at 13.9 lip., has a good torque figure at both high and medium speeds. The body, built by the Austin concern, is light and strong and provides comfortable seating accommodation and good protection for the driver. The interior length of the body is 5 ft., its width 4 ft. 8 ins, and its height 4 ft.

The new 7 h.p. model now has a longer wheelbase (actually 6 ins.), and, although the weight-carrying capacity has not been increased, the loading space has been considerably enlarged. The chief dimensions of the new van are as follow :—Length, 3 ft. 4,1 ins.; width, 3 ft. 11 ins.; height, 3 ft. 5 ins.; giving a capacity of 46 cubic ft.; the price is £110.

On the 20 h.p. ambulance chassis a new coachbuilt body, giving a low loading line, will be shown. The engine and transmission are off-set. Hydraulically operated doublestretcher dear is included, whilst ample accommodation is provided for sitting cases. Another ambulance body will be shown mounted on the 12 h.p. four-cylinder chassis.

Other models to be exhibited are a Windsor 12 h.p. traveller's brougham, priced at £285 10s. and a 12 h.p. taxicab costing £377 10s.

BAICO Stand 147 Six-wheeler and Forward-control Conversions; Supplementary Springs

CONVERSIONS of four-wheelers into six-wheelers by the system of Baico Patents, Ltd., 327-329, High Road, London, W.4, can be effected with all ordinary types of commercial chassis, and, in order further to increase the loadcarrying space in cases where particularly bulky goods have to be transported, the company has, of late, specialized in forward-control conversions on the Bake-Scott principle. Both the forward-control conversion and the latest Baico six-wheeler extension will be displayed.

In the six-wheeler conversion two semi-elliptic springs are used on each side to support the frame at three points. In plan they overlap, so that the bogie wheelbase is kept short, the adjacent spring ends on each side being connected by a shackle and a balance lever, pivoted on a cross-tube, whilst the rear end of each trailing-axle spring is linked by a long shackle to the frame. The trailing axle has under D34 slung springs. Baico Extenda and Stabilizer supplementary springing, to permit standard chassis to resist rather rough usage, will also be seen on the stand.

BEARDMORE Stand 40 New High-powered 15-ton Multi-wheeled Vehicles. Also 10-ton and 10-12-ion Models

SINCE William Beardmore and Co., Ltd., took over the manufacturing rights for this country of the multiwheeled vehicles that were seen at the Olympia Show in 1929 under the French name of Chenard-Walcker, there has been a tendency to equip them with much bigger engines.

As indicated in the article which we published on August 25th, the latest 15-tonner (the Python) has a 90 b.b.p.\ sixcylindered engine, and a still more powerful 15-tonner, the Anaconda, for work in hilly country, is also available and will be exhibited, this having a six-cylindered engine giving 115 b.h.p. For smaller loads there is the Python 10-12touner, whiNt the smallest of the range, the Cobra 50 b.h.p, 10-tonner, is comparable with the standard machine of two years ago. All four models will be seen at Olympia.

The Anaconda has a loading platform 20 ft. long, the Python also, whilst the small Python will be seen with a fully enclosed body 22 ft. long, suitable for parcels, furniture or similar bulky goods. Finally, the Cobra will appear without a trailing unit.

For those of our readers who are not familiar with this chassis the unique feature of its interlocking-ring turntable needs explanation. It -has no king pin, and the locking of the upper and lower rings makes it possible to fit a rigid, swan-neck drawbar, and, if necessary, to use this to raise

the whole fore-carriage clear of the ground. Means are provided in the coupling pillar for transferring just as much of the trailing weight ttf the driving axle as is required to obtain the necessary road adhesion.

NrEIV Bedford passenger models for 14 to 20 seats are .1_11 built at the works of Vauxhall Motors, Ltd., Luton, which concern is a branch of General Motors, Ltd. They have been specially designed to meet Ministry of Transport requirements and will take pride of place on the company's

stand, althoughgoods carriers for 2-ton loads are sure to' be closely exmined.

• Both goods and passenger models are available in two wheelbase lengths, 10 ft. 11 ins. and 13 ft. 1 in., the longer chassis having a divided propeller shaft. All sizes have fullfloating back axles. Examples of the long 2-tonner and 20-passenger chassis will be in the collective exhibit.

A comparatively powerful engine developing its best output at a moderate speed is the basis of the Bedford design. It is a six-cylindered, overhead-valve, four-hearing engine of 44 b.h.p. All models have a four-speed gearbox and a, top-gear ratio of 5.8 to 1. The passenger models have chromium-plated radiator shells and wide bus-type bonnets.

On Stand 100 will be fwo 20-seater buses with coachwork by Duple Bodies and Motors, Ltd., and the Lincolnshire Road Car Co., Ltd. (prices, respectively, £550 and £545), a long 2-tonner with Luton body at £285, a sheep float and a general farmer's wagon on a short 2-tonner, at £283, and a.14-seater bus with Grose coachwork at £485.

BEHNA Stand 72

Heavy Lorries for Loads 0 Six Tons or, with Trailer, About 12 Tons

MLLE Berna oil and petrol-engined 6-tanners are built ..11_ for hauling 6-ton trailers. The cylinder dimensions of both engines are the same and have not been changed since the Olympia Show of 1929, the bore being 11_5 mm. and the stroke 170 ram. In addition to some minor improvements in the engines, the final drive of the rear wheels has been entirely redesigned and improved. It is still of the double-reduction type employing a dead load-carrying axle, and exposed shafts from the spiral-bevel-drive case, carrying pinions which engage with internally toothed rings on the wheeb but in the new design the pinion-and-ring drive is enclos i and operates in an oil bath, and this component is comph -ely separate from the brake-shoe mechanism, So that t cannot possibly get on to the brake facings. The arram ,ment is ingenious when one considers that there are two p irs of brake shoes, one beside the other, and, despite this, le unit is compact. Hydraulic brake-shoe operation is pre ided, the cylinders being mounted above the centre of the axle, where they are accessible for adjustment, etc. , It : expected that Lawson Pigott Motors, the British conce ionnaire, will show a four-cylinder petrol-engined vehid with tipping gear and, separately, a Dents oil engine.

BRAS 411114 Stand 117 .Tew'Double-decker, Longand Short-wheelbase Single-decker Chassis

THal lengt1 company DOW produces a double-deck bus chassis, its single-deck type is available in two . wheelbase and with either four or six-cylindered engines. Of the .ypes that will be displayed, two represent entirely wdels which were described in Our issue dated r 20th. These are the G-type double-deck-bus chassis, has a six-cylindered 103 b.h.p. engine, and the H-type heelhase four-cylindered single-decker chassis, one of .w chassis having this wheelbase of 17 ft. 6 ins. It • remembered that the company's B. type and D-type lecher chassis with respectively four-cylindered and inhered engines, have wheelhases of ta ft. new double-decker will appear OS a chassis, also as late bus seating 48 passengers. Ample power, a strong

main features are the tures of this new chassis, on which Dewandre vacuum braking is standardized.

Features of the H-type long single-decker chassis are the

un front-brake mounting of the ont-brake vacuum. cylinders on the wheels, and the new design of gearhox. The. braking equipment of these vehicles will be ..of particular interest in view of the Minister of Transport's fresh attention to regulations on this subject. The short-wheelbase six-cylinder single-decker chassis is practically the same model as that the performance of which was dealt with in our issue dated December 30th, 1930. The engine incorporated is the same model as fitted in the double-decker.

Trailers, Semi-trailers and Articulated Vehicles

rrHE well-known Carrimore concern continues to specialize • in the manufacture of trailers and semi-trailers. At this year's Show rather an imposing selection of its products will be staged. The company has electric welding plant at its Finchley works, and is able to produce chassis frames of the welded, riveted or bolted variety. For loads of up to about five tons a pressed-steel frame is becoming popular and an example of this kind of trailer, suitable for 45-tan loads, will be shown, mounted upon 34.-in. by 7-in. tyres, and having 15-in, rear-wheel brake drums. Two other four-wheeled trailers will be on show, these comprising a 6-tonner with, an electrically welded frame and a 4-tanner having a big box-van body carried on a riveted frame of the full-width kind. On the semi-trailer side two examples' of the Quickfit detachable unit will be shown. One of these is to be mounted on a Bedford short-wheelbase 2-ton chassis and will have a, drop-sided body 18 ft. long, said to be suitable for loads up to 5 tons. • The other, exhibited without its tractor, wig Lave a body 20 ft. long. This is for loads of 3 tons to 4 tonS and is suitable for the Ford 30-ewt. chassis. At the Olympia Show in 1929 the Carrimore Lynx articulated vehicle, intended for loads of about. 10 tons, creatdi quite an impression, being then a newcomer. It will now` be seen in its latest form, the motive unit having a wheelbase of 10 ft. instead of 9 ft., and a Still-tube radiator.

CHEVROLET Stands 34 and 130 British-built 12-cwt. and 30-cwt. Chassis and Vehicles

A' in previous exhibitions, a fine display of Chevrolet 12-cwtand 30-cwt, vehicles will be staged, but a feature to be stressed on this occasion is that they are new entirely British-built with British materials at the works at Luton, where they have been in production since about February, 1930. In fundamentals of design, the two chassis are practically unchanged from their 1929 specifications. Both have the D35

same type of six-cylindered, overhead-valve engine of 26.33 h.p. treasury rating. The wheelbase of the 12-cwt. model is S ft. 11 ins., the chassis weight 15 cwt., and the rear-axle ratio 8.8 to 1, whilst the 30-cwt. chassis has a wheelbase of 10 ft. 11 ins., a weight of 23f cwt., and a finaldrive ratio of 4.9 to 1. The former has a three-speed, and the latter a four-speed gearbox.

Examples of the smaller and the larger chassis will be seen in the collective chassis exhibit in the Empire Hall, whilst on Stand 34 will be an array of vehicles, including a 12-cwt. delivery van and lorry costing £175 and £176, respectively, a 30-cwt. van at £235, a 30-cwt. lorry at £212, a travelling shop, a three-stretcher ambulance, a farmer's wagon at £240, and, finally, a 30-cwt. drop-side lorry with a set of special fitments which allow it to be quickly converted into either a builder's lorry (with timber bolster), a market gardener's lorry with high loading rack, a utility vehicle, or a flat-platform lorry.

CITROEN Stands 68 and 132 New Engines in 2-ton Chassis, Rigid Six-wheeler and Tractor, also Smaller Models

NXTHILST the six-cylindered engine of 72 mm. bore and V 100 mm. stroke (Treasury rating 19.3 h.p.) is still available, and the CitroUri Company will again at this Show

exhibit its 35-40-cwt. chassis embodying this power unit, it is clear that the new 2-tonner or 20-passenger model, with a somewhat similar engine, but of 75 mm. bore, is more likely to be concentrated upon. The general specificatiou of the newcomer does not greatly differ from the less powerful model. The wheelbase is 13 ft. 11 ins., and there is a four-speed gearbox. A bare chassis will be shown, also one equipped as a 20-seater coach with body by Grose, Ltd., of Northampton.

A. modification of the 2-ton chassis is a. trailingaxle, rigid six-wheeler, also to be upon the stand. In this case the wheelbase to the bogie centre is 15 ft. 5 ins., and a special rear axle with double-reduction gear is fitted. The chassis is intended for loads of 34 tons.

Another modification of the 2-tonner is a tractor of 9 ft. 49 ins. wheelbase, and it will be shown with a three-seater cab and automatic trailer-attachment device. As an articulated vehicle the outfit is suitable for loads of five tons. As mentioned above' the 35-ewt. chassis embodying the 72 ram. engine is to be exhibited and it will have a threeway, hydraulic tipping body.

A new 25-ewt. van with four-cylindered engine of the larger bore will also be shown, and the same type of chassis will appear as the basis of an 11-12-seater hotel bus, and a traveller's brougham. Two Citron-K6gresse models will also be on the stand. These possess a strong appeal to the estate manager or agriculturist who is looking out for a dual-purpose machine.

COMMER Stands 113 and 130

Innovations Include 30-cwt, and 2-ton Chassis, also 20 and 24-26-seater Coaches

1-11JRING the past few weeks the Commer range has

been extended by the addition of the Raider 30-cwt. chassis, the Centaur 2-ton model, the Centaur 20-passenger type and the Corinthian 24-26-seater 'chassis. Particularly in the case of the Raider and Centaurs interest is certain to be widespread, on account of the popular prices at which the chassis in question are listed. Despite this fact, the factor of safety throughout the construction of the serious components is of a high order.

Two examples of the Raider will be shown, one in chassis ia86 form and the other with a drop-side lorry body. The coachwork also is a Coramer product, and the vehicle sells at £267 complete. This model has a 56 b.h.p. engine of the side-valve, six-cylindered variety, and it employs selfenergizing four-wheel brakes.

Having the same engine, will be the Centaur 2-ton chassis; in this case it will be a long-wheelbase model intended to carry a body with a loading space up to 11 ft. 6 ins, behind the driver. The Centaur has a fully floating rear axle and the chassis is priced at 1265.

An example of the established range of goods models will be the GF5 5-ton tilt van with forward control. Its engine develops 74 b.h.p. at 2,000 r.p.m.; in the form shown the price is £998.

Those who visit Olympia will find that the chassis with set-back front axles are becoming increasingly .popular. This feature was pioneered in this country by CoMmer Cars, Ltd.; one of the latest examples of the G6, with this feature, will be shown as a 6-6i-ton platform lorry. This model has a really powerful six-cylindered engine, which gives it a generous performance, either for main-road work or as a chassis for a tipping vehicle.

In its passenger form the new Centaur will be shown as a 20-seater bus with a Willowbrook body ; the price of thb complete vehicle is £505. Another coach will be the Invader 20-seater. This chassis, of course, pioneered the silent third speed for commercial vehicles. Another novelty will be the 24-26-seater coach, known as the Corinthian. This also has

CROSSLEY Stands 104 and 132 A New Oil-engined 6-ton Chassis and Several Fine Passenger Vehieles JARGE oil-enghaed vehicles will occupy a prominent

place in the Crossley programme. In addition to a number of passenger vehicles, a 6-ton heavy-duty chassis will be shown for the first time, The design of this vehicle incorporates well-known Crossley features, and the machine is equipped with the company's oil engine. With six

cylinders of 4 76. ins, bore and a piston stroke of 6 ins, the unit develops about 100 b.h.p. at maximum r.p.m.

All the auxiliaries which might require periodic attention are mounted on the near side, where they are accessible. A valveless single-plunger type fuel pump with an injection advancing and retarding device is included in the specification, likewise pump water circulation and high-pressure lubrication. The transmission incorporates a four-speed gearbox with right-hand control and a fully floating rear axle having a double-reduction gear. Four-wheel brakes are operated by the pedal, the rear shoes being applied through a master vacuum-servo motor, whilst each of the front brakes has a servo cylinder which acts directly on the cam operating levers. With 40-in. by 8-in, giant pneumatic tyres (twins at the rear) the price of this model is £1,440.

This compression-ignition power unit will also be featured in a double-deck chassis and a 00-seater double-saloon bus.

The wheelbase and track dimensions or these vehicles are 16 ft. 7h ins. and 6 ft. 3-11 ins. (front) and 5 ft. 10/ (rear) respectively. Incidentally, a special " automatic " gear-change device is built into the transmission on the chassis.

Two petrol-engined vehicles will also be shown, both of which have the Crossley Alpha 38-110 h.p. six-cylindered engine. One will be a 32-seater service-type bus and the other a luxury coach.

DAIMLER Stands 61 and 132 Large Passenger Vehicles Incorporating Fluid Flywheels and Pre-selective Gearboxes

ALL Daimler bus and coach chassis are equipped with six-cylindered engines, and this year operators will see for the first time the poppet-valve type, which has been standardized in addition to the normal Daimler sleeve-valve engine. The new unit is characterized externally by clean lines, and it is obvious to any discriminating observer that it is exceedingly rigid in construction. By developing a special cam profile, a much greater tolerance in tappet adjustment than is usually considered desirable is provided.

The unit has bore and stroke dimensions of 103.5 mm. and 130 mm. (6,561 c.c.) respectively, vertically disposed valves in the cylinder head being operated by push rods and rockers from a chain-driven camshaft located in the crankcase. As might be expected, a seven-bearing crankshaft of large diameter is installed, and aluminium-alloy pistons, together with light-section connecting rods, combine to keep reciprocating stresses low.

In the chassis to be shown, the Daimler patented Fluid Flywheel transmission, which, of course, incorporates the ingenious four-speed pre-selective gearbox, is used. This arrangement allows the engine to "idle" with a gear engaged, without causing the vehicle to move forward. By speeding up the engine, however, the driving torque' is increased by the hydraulic clutch, and the load is taken up smoothly and silently.

Actually four vehicles are to be shown on the Daittlier stand, one being a poppet-valve-engined chassis with a double-deck body, and the other three consisting of two complete double-deckers and a C.H.6 saloon coach having a Duple body. • • The sleeve-valve engine will be seen in the three complete vehicles. This power unit is of slightly smaller capacity than the poppet-valve type, having a cylinder bore of 97 mm. and a piston stroke of 180 mm., which gives a total swept volume of 5,764 c.c. The double sleeve valves are operated by small connecting rods from a chain-driven eccentric shaft, special arrangements being made in the oiling system to provide adequate lubrication of the working surfaces in the sleeves when the engine is first started up.

DENNIS Stands 63 and 131 New Single-decker and 31-ton Chassis, as well as the Latest Forms of Popular Models The Y reason of the fact that three of the well-known Lance _Li chassis will be shown, two equipped with bodies, priority of place is given to this model. They will prove to he among the most interesting exhibits in this class. The well-known six-eylinclered engine with the special design of overheadvalve gear is, of course, continued. The output is 100 b.h.p., and new points in the engine are the independent oil filter and cooler and the deeply corrugated sump.

An ingenious feature is the divided air path under the bonnet, so that the air stream from the exhaust pipe does not impinge upon the dynamo. Silentbloc bearings are now used for all the shackles, and an interesting feature is the method in which dismantling and reassembling can be effected by means of the withdrawal of cotter bolts. Other Lance chassis will be available with a 54-seater Brush body and an all-steel 48-seater Metropolitan-Caramell body.

Another popular six-cylindered Dennis model to be displayed will be the normal-control Arrow coach, which has a companion specification to that of the Lance. The coachwork of this exhibit will be of the luxury 32-seater type by Duple Bodies and Motors. Ltd.

An interesting new machine, which is described on other pages in this issue, is the new Dennis Lancet chassis for single-deck bus bodies.

Turning to the goods models, the smallest is one of the 30-cwt. forward-control chassis, which, in standard form, sells at £315. The four-cylindered engine develops 40 b.h.p. at 2,000 r.p.m., so that the output is adequate for all requirements. This model has a wheelbase of 11 ft. and offers a body space up to 12 ft. 10 ins.

An entirely new model to be shown for the first time will be the 3i-ton chassis. This has a four-cylindered engine of 110 mm. bore and 150 nun. stroke. In order to obtain the utmost power from it, a special induction pipe and turbulent head are used. The braking system embodies hydraulic operation, coupled with a servo. In standard form the Chassis costs £555.

The final exhibit on this stand will be a six-cylinder fire-engine with a 600-700-gallon multi-stage turbine pump.

In the Empire Hall will be a 6.ton forward-control chassis and one of the 12-ton rigid six-wheelers, in which will be mounted a Dennis six-eylindered, compression-ignition engine, shown for the first time. It develops 95 b.h.p. at 2,000 r.p.tu.

DODGE BROTHERS Stand 58 New Four-cylinder 2-tanner. Range of other Models of from 15-cwt. to 4-tons Capacity

T'

■ new four-cylinder 2-tonner, of which a full description and performance report were given in our road-test article of September 29th, is probably the most important model on the Dodge Brothers' stand. It has the same size of engine as the 15-cwt. and 30-cwt. chassis. Of these, which also are popular types, the 15-cwt. machine will be shown as an express van, and the 30-cwt. machine as a van and as a drop-sided lorry. The wheelbase of the lorry is 11 ft. 4 ins. The 2-tanner with similar wheelbase will be shown as a hand-operated end-iipper, and a long-wheelbase example (13 ft. 9 ins.) will appear as a large-capacity Luton van. In addition, there will be the more expensive six-cylinder 2k-tanner, a 3-tanner and a 4-tonner, the two last-named being equipped with a rather larger model of six-cylindered engine. The 2e-tonner will be exhibited as a three-way tipper and the two larger models as bare chassis. The former flee a wheelbase of 13 ft. 9 ins., and the latter one of 16 ft. 3 ins.

FLEXION Stand 141 New Balance-beam Six-wheeler Conversions; New Tipping Gear; Forward-control Conversion

MILEXION is a name well known amongst users of trail ing-axle, rigid six-wheelers. Flexion Products, Ltd., The Hyde, London, N.W.9, will show a Bedford short-wheelbase chassis equipped with the Flexion Mark III six-wheeler sonversion set. On this will be mounted the new Flexion nechanieal-tipping gear operated through redaction gearing from a gearbox power take-off. The advantages of this tipping mechanism are its moderate weight, its enclosed searing and the ease with which it can be fitted.

As regards the Flexion conversion system, it embodies balance beams which give the frame six points of support upon the bogie. The balance beams in the latest model are castings, and grouped lubrication system is employed.

The rear portion of another Bedford chassis will be seen equipped with the Mark IV extension unit. This is similar to the one above described, but the frame is supported at four points on each side, giving in all eight points of support upon the bogie, and, in particular, support at the end of the rear overhang.

On the same stand will be shown the adaptation of the Flexion-Scott forward-control conversion to the Bedford chassis.

readers of7'1cri ie Commercial Motor. It has a six-bearing e crankshaft, and the crankcase mbodteS inspection doors, which permit an overhaul to be effected without removing the engine from the chassis. The speed is governed to 1,300 r.p.m.

The gearbox of this vehicle provides four forward speeds; the teeth are made especially large to suit the heavy torque of an oil engine. It is, of course, a shaft-driven vehicle with a worm-type axle, and the four-wheel brakes have a servo, whilst the hand brake works on a drum in the transmission line. The chassis has a wheelbase of 13 ft. 8i ins.

Two steam vehicles will be shown. The first will be one of the well-known Speed Six models with a three-way hydraulic tipping gear. For this work the chassis is of the short type, with the water tanks behind the cab instead of at the rear. The body is 12 ft. long and is steel lined. This model was the pioneer of high-speed pneumatic-tyred steamers, as they are known to-day. It can carry six tons at a legal speed of 20 m.p.h., with a maximum speed far in excess of this figure. A horizontal boiler is employed, working at a pressure of 275 lb. per sq. in, The engine is horizontally mounted below the chassis and is unit-coupled to a two-speed gearbox, giving overall ratios of 4.2 to 1 and 13 to 1. Final drive is by shaft. The service brake takes effect on all four wheels ; the Sneed Six introduced this feature at the 1929 Show, so far as steam wagons are concerned. TN driver's effort is assisted by use, of a steam operating system. Tipping gear is of the hydraulic type, directly operated by the boiler feed pump. The second steam vehicle will be the Speed Twelve, which is the rigid six-wheeler development of the model previously' referred to. It will carry 10-12 tons and embodies a similar type of boiler and engine. Both axles of the bogie are driven, and a third differential is interposed. In this case the exhibit will have a platform body 20 ft. in length and 6 ft. 9 ins. wide.

FOWLER Stand 148

Highly Developed Oil-engined Vehicles With an Unusual Range of Performance -E101/ many years the Fowler concern has been producing 12 compression-ignition engines. As might be expected, the products of the concern reveal concrete evidence of this experience. The new Fowler engine runs with a marked degree of silence throughout -its useful range of speed, and the inherent fuel economy of the compression-ignition engine is maintained, even at unusually high road speeds, by utilization of eight forward ratios. Behind the clutch is a two-speed gearbox; farther back, and separately mounted, is a four-speed box. The drive ,passes from the engine through a multiple-plate clutch, which is specially ventilated. Using direct drive in the main gearbox and the geared-up speed of the auxiliary, giving a ratio of 3.9 to 1 with a fourwheeled model, it is possible to obtain over 50 m.p.h. AR regards the exhibits, these will consist of a fourwheeled 6-7-ton lorry, coupled to a Fowler 5-6-ton pneumatic

tyred trailer. The overall length of the lorry is 25 ft.; this model employs a double-reduction rear axle of the beveland-spur type. Vacuum-servo braking takes effect on the four wheels, and a mechanical feature of merit is that a reservoir is provided so that a vacuum is always available, even when the engine is at rest. The other exhibit will consist of the 10-12-ton rigid six-wheeler with the new Fowler 90-bh.p. six-cylindered engine.' A special feature of the design is that each piston head embodies a cavity which communicates with the combustion chamber by means of holes. The presence of this cavity causes, it is claimed, a delay action during combustion, thereby prolonging the expansion period and eliminating, to a large extent, what is commonly known as "Diesel knock." This chassis, again, employs eight forward speeds, and the drive is taken to all four wheels of the bogie; three differentials are used in order to reduce tyre wear.

Complete Range Typified by Six Striking Finished in Uniform Colour Scheme. GARNER Models Complete Range Typified by Six Striking A PROMINENT position in the centre gangway of the 1-X. Grand Hall will be occupied by the six Garner exhibits; these will all be finished in attractive shades of green with red wheels. By an, ingenious display of forethought it has been possible to provide that these machines will exemplify the whole range of models. Special interest centres around the new 2-ton four-wheelers and the 3-ton trailing-axle machines, whilst the low-loading types also are of recent introduction.

Shown in chassis form will be the ABM (normal control) model with a four-cylindered engine. The particular chassis will be of 11-ft. wheelbase. The loading space is generous in relation to the overall length. Another 2-tonner will. be shown in the form of a .boxvan, but in this case the engine has six cylinders and is of the side-valve variety. In the form exhibited the vehicle weighs under 2i tons, so that its legal speed limit is 30 m.p.h. As typifying the new trailing-axle six-wheelers; there will

be on view a forward-control machine with a four-cylindered engine. Special interest centres around the bogie. The axles are offset in relation to the springs, the free .,ends of which are coupled by levers having angles of slightly less than 90 degrees. These compensators work after the manner of the steering layout of a vehicle. It is important to note that the permissible variation in relative axle height is no less than 5 ins.

Another new machine will be the low-loading type, in this case a 3-ton model is to be shown as a chassis. Pneumatics will be installed on the exhibit but solids may be specified if required. Frequently machines with specially low-frame levels are somewhat restricted as to speed ; in the case of this Garner it can attain some 35 m.p.h., which enables it to be used for long-distance work as well as for urban service. It forms a good basis for a 10 cubic yard refuse-collector body.

One of the familiar types, which have been proved during many years of work, is the A.J. 3-tonner ; an example of this type of chassis will be shown as a normal-control tipping lorry. This machine has a wheelbase of 11 ft. 3 ins.,-so that it can conveniently be used in districts where 12-ft. weighbridges are common. The size of the loading space is favourably affected by the cowl construction of the dash.

Finally there will be a forward-control tilt van mounted upon a J06 33.-4-ton chassis. This model is expressly designed for high-speed, long-distance work ; its high powerto-weight ratio guarantees a good average speed, coupled with a reasonable fuel-consumption rate. The usual Garner system of pivotally mounted front wings gives genuine accessibility to the power unit.

GARRETT . Stand 90 An Oil-engined Lorry, a PowerfulIndustrial

Tractor and a Revised Six-wheeled Steamer.

ALL of the three exhibits which will be shown by Richard ...Garrett and. Sons, Ltd., which is associated with Agricultural and General Engineers, Ltd., will be of particular interest on account of the fact that novelty, attaches to each one. The oil-engined lorry made its first public appearance at the Royal Show, at Warwick, this year. It embodies the well-known Blackstone engine, which has sixcylinders and develops in the neighbourhood of 60 b.h.p. at

1,000 r.p.m. The model to be shown will have a fiat platform body.

Turning to more intimate details of its construction, we find that the engine is unique in respect of its injection system. This is a special feature of the Blackstone and does away with the necessity of a metering pump and highpressure pipe lines. This engine is capable of using fuels somewhat heavier than are commonly employed for oilengined vehicles. Starting is by means of a 24-volt electric motor, but it can be set in motion by means of the ordinary handle ; the compression ratio is 14 to 1. The drive passes through a four-speed gearbox, the third speed is of the silent type. All wheels are shod with 40-in. by 8-in. tyres.

Another oil-engined product to be shown will be the new industrial tractor, equipped with pneumatic tyres. The particular example will have' an Aveling and Porter Invicta engine, but the Blackstone power unit can be installed in the same chassis. The output is 42 b.h.p. and either electric starting, hand starting or a petrol donkey engine can be employed.

The third model to be shown on the stand will be the rigid six-wheeled steam wagon in its latest form. It now has 20-in. by 12-in. pneumatics on the front wheels and 40-in. by 8-in. tin tyres on the ,wheels of the bogie. The" third axle is of the trailing type, but the layout of the bogie is similar to that which has been a Garrett feature for several years. The exhibit will have a 17-ft. 6-in, body with a movable floor of the Principality type.

CO this stand will

be seen the most unorthodox of all

O vehicles at this year's Olympia Show. The Gilford front-drive passenger vehicle has been in the process of building for well over a year, and follows a line of advance which has frequently been indicated in this journal. It is not necessary to give any technical details here because a full descripton with ample illustrations appears elsewhere in this issue. Suffice it to say, however, that one steps from the ground directly on to the main-floor level, which is at a height of 1 ft. 11 in. It is to be hoped that the location of the power unit within a cowling that protrudes about 4 ft. into the saloon from the front bulkhead will not result in any undue noise, so that the advantages of the front drive and the ingenious economy of space made possible by the hollow worm shaft (which permits the mounting of the gearbox neatly in front of the finaldrive worm wheel) may be appreciated to the fulL In addition to the double-decker, the latest M.O.T.-type six-cylinder 26-seater coach designed to meet the Ministry's requirements and having a wheelbase of 16 ft. 8 ins., and bodywork by Strachans (Acton), Ltd., will constitute an interesting exhibit. There will also be the familiar 1680Ttype 32-seater of similar wheelbase. On the goods-carrying side the company will show the DF6 six-cylindered chassis equipped with a Newns double horsebox body. The wheelbase of this model is 14 ft.

From the oil-engine point of view, it is satisfactory to note that the power unit of the unique double-decker is to be seen as a separate exhibit It has six cylinders in line with 12 opposed pistons working on upper and lower crankshafts linked by a train of gears, and it works on the twostroke-cycle principle

GITY Stands 33 and 133 Goods and Passenger Vehicles Including an 11-tonner with an Oil Engine

ONE of the biggest vehicles to be seen at Olympia will be the Guy Goliath 11-ton chassis which, with a wheelbase of 17 ft. and an articulating bogie axle at the rear, is powered by a six-cylindered compression-ignition engine. A frame 12 ins, deep, having 31 ins, flanges, appears to be amply strong to deal with even a badly mounted load in the 22-ft. body space provided, and the tyre equipment, involving the use of 40-in. by 8-in. tyres with twins to each of the four wheels of the bogie, seems to be adequate. The Gardner six-cylindered engine, which forms the power unit, needs no introduction. Over 100 b.h.p. is developed at 1,650 r.p.m. despite the moderate R.A.C. rating of 43.5 h.p. The power-weight ratio therefore is such as to give the vehicle an excellent all-round performance, especially bearing in mind the feet that an auxiliary two-speed gearbox is included in addition to the normal four-speed type.

A 51-seater double-deck Invincible four-wheeled bus is also to be shown, this vehicle being powered by the Guy company's well-known six-cylindered 110-b.h.p. petrol engine. This particular model has a wheelbase of 16 ft. 7i ins., which provides a body space (measured from the:dash to the end of the frame) of 20 ft. 2 ins, without exceeding M.O.T. regulations.

The largest passenger vehicle to be seen will be a sixwheeled 56-60-seater trolley-bus, the chassis for which has a wheelbase of 16 ft. ft ins, and is powered by a 75 b.h.p., compound-wound regenerative motor. The body is by Chas. H. Roe (1923), Ltd.

Other exhibits will include a 1,000-gallon tanker (which is powered by a four-eylindered engine of 4i ins, bore and 5i ins, piston stroke) together with a 50-cwt. chassis costing £395. The latter 'machine has a wheelbase of 12 ft. 3 ins. and a track of 4 ft. 9i ins.; it employs a four-cylindered overhead-valve engine having bore and stroke dimensions of 90 mm. and 130 ram. respectively. The exhibit will be completed by a Victory six-cylinder 20-seater service bus, the chassis price of which works out at £495.

HALLEY Stand 118 • Two Passenger and One Goods Models Shown for the First Time

"TO fewer than six vehicles are to be staged by this wellj..14 known Scottish concern, and three of them are making their first public appearance. An imposing machine will be the new Halley Neptune double-decker with a 51-seater Covvieson body. The engine has six cylinders and gives an output of 115 b.h.p. It has side valves and a Ricardo-type head ; the placing of the auxiliaries is schemed to allow genuine accessibility. For example, the magneto is transiversely mounted, whilst the oil filter is directly beneath it. Space is given for the largest type of dynamo to be carried on the near side, whilst on a tandem platform can be installed an air compressor, if Westinghouse braking be desired.

A unit-mounted gearbox gives four forward speeds and a twin-plate clutch is used. In the case of the exhibit. Dewandre braking of the new three-unit type will be employed.

Another new passenger model will be the Clansman, iemonstrated as a show-finished chassis. The seating capacity is 32-36, and it has the same six-cylindered engine ,as the Neptune.

Amongst the freight-carrying vehicles will be an example of the recently introduced G112 lorrY, which has forward eontrol anti will carry a pay-load of 6+ tons on the 20-ft. 5-in. platform. This machine has a four-cylindered engine, with a unit-mounted four-speed gearbox and final drive by en overhead worm.

A 5-ton forward-control platform lorry will be shown. This embodies the EF21 chassis of 11-ft. wheelbase. It has a turning circle only slightly greater than 40 ft. Yet another goods machine will be the 4-ton P9E1 chassis. It has. a four-cylindered engine, embodying various Ricardo patents, and is well known for its fuel economy and good D40 general performance. A four-speed gearbox is 'provided, and the brakes take effect on the rear wheels and transmission. With a 13-ft. 4-in, wheelbase it can accommodate bodies 14 ft. 2 ins. long.

Finally, there will be a 2-ton tipping lorry with a fourcylindered engine and a Bromilow and Edwards hydraulic gear, giving end discharge of the load.

HARDY Stand 70 Three Interesting Models of Unusual Performance Including a New Six-wheeler.

TN other pages in this issue we describe the new R6.8.2 amdel, which has just been added to the Hardy range. It is a rigid six-wheeler, intended for road or cross-country

service, and the secret of its success is the two-speed auxiliary gearbox, which not only affords ratios so widely differing as 8.25 to -1 and 67.3 to 1,. but automatically puts into action the drive to the front live axle when the lew series of ‘sears is working.

In addition to the new chassis, there will be an example of the Well-known 4/4 lorry With a latforni body. This vehicle has a four-cylindered A.E.C. engine ,and the same type of auxiliary gearbox as already described ; therefore, the drive passes through the two rear wheels on the high series of gears and to all four wheels on the low Aeries. This machine carries a 4-ton load, but will also haul a trailer; by reason of its eight forward speeds it is easily able to do this, The tractive effort is 6200, lb.

An interesting exhibit of primary interest to those who require a powerful pneumatic-tyred tractor will be the six wheel-drive machine carrying a winch. All three axles are of the " live " type and those at the rear embody a specially • interesting transmission system. The six-cylindered engine and four-speed gearbox are mounted in a sub-frame and drive through an auxiliary gearbox, from which power can be taken to the winch when required. An automatic layering gear is used, and there are drawbars at both ends.

HENSCHEis Stand 50 Long-distance Bus With 250 h.h,p. 12-cylindered Engine

(A NE pf the mechanical novelties at Olympia is certain Urto be the huge Henschel bus chassis with an engine of no less than 250 b.h.p. This model is a six-wheeler and is intended for long-distance service. The chassis weighs 6 tons 7 cwt. and affords a body space of 32 ft.

Naturally, interest centres in the engine desikn. There are two banks of six cylinders each, placed side by side, each having its own inlet and exhaust system, but a single centrally placed camshaft operates push rods between the cylinder blocks and regulates the opening of all 24 valves.

The .crarikShafts are coupled at both ends by herring-bone gears. The four forward speeds are always in mesh and they are engaged by dogs. In order to economise in fuel, a geared-up top speed is provided.

Although this model is new to this country, it has been exhibited in Germany, which is, of course, its country of origin. A notable feature of this machine is the hand brake, ;which is put into action by two progressively working hand levers. The service brake takes effect on all six wheels and operates through a vacuum servo.

HILLMAN Stand 97 Two New Van Chassis Make Their First Appearance

Arnw weeks ago we made the first announcement of the entry,. of the Hillman' Motor Car Co., Ltd., into the commercial field. The larger chassis employed is a loaieal develOpment of the popular Wizard ear, which was evolved not aply for service in this country, but for the more arduous work, overseas, 'The chassis has a wheelbaie of 9 ft. 3 ins. The van. will carry 15 cwt., and ha S internal body dimensions of 6 ft. by 4ft.' 7 ins: by 4 ft 1 in. The seat beside the driver is readily detachable. six-Cylindered side-valve engine of 20.9 h.p., R.A.C. riting, is employed. It has a .four-bearing crankshaftand

the pistons are in cast iron. The gearbox provides four forward speeds, third gear being of the silent type. Hotchkiss drive is used to an axle which has semi-floating shafts.

The other model to be shown will be the new Minx chassis, developed as a 6-cwt. van, with a four-cylindered engine of 9.8 h.p., R.A.C. rating. It has a three-speed gearbox and a semi-floating rear axle. The wheelbase is 7 ft. 8 ins. and 4i-in. tyres are used.

INTERNATIONAL Stand 89 New Heavy-duty Models, Including a 5-tonner for Semi-trailer Work With 10 Tons

AFEATURE of the range of International products is the way heavy-duty models have been added in the past year or so. In March, 1030, the 3-tonner was the biggest chassis on sale in this country. Now the AG, for example, is available, a 5-tonner of 67 b.h.p., with five-speed gearbox and double-reduction hack axle. In short-wheelbase form, with detachable semi-trailer, this chassis will deal with 10-ton loads. One is to be exhibited.

The AL3 2F3-tonner will be seen as a drop-side lorry with an enclosed cab, and there will be a 30-40-cwt. chassis on the stand. The A5 with a wheelbase of 17 ft. 6 ins. will be seen as a 30-seater bus, and, of course, the model-20 tractor equipped for industrial work is to be shown. No International display would be complete without the tractor. For industrial purposes this machine has pneumatic tyres.

The fact that a distinctly better performance can be obtained with a heavy vehicle if a multi-speed gearbox be fitted finds recognition in the AG chassis referred to above. Whether used for carrying 5 tons or as the basis of an articulated vehicle dealing with 10 tons, the machine has a five-speed gearbox and double-reduction driving axle. This means that on level stretches of road higher speeds and greater economy are obtained.

JAMES Stand 158 Examples of the 5-cwt. Samson Handyvart

THE James Samson Handyvan is a neat and serviceable little machine for loads of 5 cwt., which will be exhibited in the form of a complete van with the body coming to the top of the hood, as a model for dairymen and as a stripped chassis.

The standard body gives a capacity of 30 collie ft., although a larger body of 36 cubic ft. can he supplied. It is a three-wheeler with what may be termed a motorcycle front, powered by a James 5 h.p. side-valve twin-cylindered engine with detachable heads and automatic lubrication.

It drives through a multi-plate clutch to a James threespeed gear, Renold chains passing from this to the rear axle, which is of the semi-floating type with a steel outer casing. Powerful internal-expanding brakes are provided on the rear wheels. These are pedal-operated and compensated, whilst there is a ratchet hand lever for use when standing. Good protection is afforded the driver. The price complete is £86.

30WETT Stand 35 Economical Two-eyiinder Light Vehicles

mHE Jowett chassis is almost a replica of the pleasure-1_ ear model, which has proved itself to be sound and reliable. With wheelbase and track dimensions of 8 ft. ins. and 3 ft. 9 ins. respectively a good body space is available.

Rated at 7 h.p., the engine has two horizontally opposed

cylinders having a bore of 75 mm. and a piston stroke of 101.5 mm. (907 c.c.). Side valves and detachable cylinder heads are features, innovations in this year's models taking the form of removable tappet guides and a modification in the shape of the cams, etc., to render the tappet gear even, quieter in operation.

The van to be shown has a load capacity of 70 cubic ft. and is priced at £138. Open and covered lorries are also to' be exhibited.

HARRIER Stands 65, 131 and 143 Three, Four and Six-wheeled Vehicles for a Wide Variety of Industrial Purposes

FROM the point cif view of the variety of exhibits, the groups of Karriers will be noteworthy. For example, on Stand 65 will be found machines ranging from three-wheeled tractors and three-wheeled 2-tormers to 12-ton six-wheelers and an oil-engined six-wheeled double-decker. Another group on Stand 143 consists of three-wheeled chassis. Dealing with the first group, there will be the new -Victor 2i-tanner with a lorry body and forward control. The wheelbase is 12 ft., and the power unit is a 48 b.h.p. fourcylindered engine. At the other end of the scale is the new Colossus 12-ton six-wheeler with a lorry body and cab. This has a mean wheelbase of 17 ft. 1 in. The third axle trails.

In view of the popular interest in the compression-ignition engine, many will be drawn to the Karricr Consort six wheeled double-deck chassis, which will be shown with a Gardner six-cylindered engine.

Embodying another form of prime mover is-the KarrierCloug,h six-wheeled double-deck trolley-bus chassis, which is surmounted by a 60-seater•body. • Next we coma to a group of three three-wheeled machines

of the kind which the Karrier concern has done much to pioneer. The Colt will be ISt01$91 with a hand operated cud-tipping body. This model has a twin-cylindered engine and a 9-ft. wheelbase ; it is mounted on pneumatic tyres. The Cob to be shown will be the three-wheeled tractor permanently_attached to a two-wheeled trailer. A new machine

will be the Earripr Cob Major, similar in many respects, but it hauls a 4-ton detachable trailer, and the power unit is of the four-cylindered type.

In the collective chassis exhibit will be found one of the new Victor chassis for 21--ton loads, and an example of the Consul, which is based on the well-known K-type models. It -will carry a 6k-ton load; it has 16-ft. wheelbase and forward control.

On Stand 143 will be found a Colt three-wheeled lorry -with a twin-cylindered engine. This machine will have solid tyres. Another Colt chassis will carry a special inter-works stores body, with a nest of trays at the forward end. This, again, will have solid tyres. Finally, there will be a Cob tractor suitable for coupling to existing horse-drawn drays. The outfit is capable of dealing with a 3-ton load.

LATIL Stand 25 A New Chassis for Semi-trailer Work and a New High-speed Si-tomer; also the Familiar Models

THIS concern continues to offer its range of well-built French chassis for loads of from 35 cwt. to approximately 10 tons. The 135 6-tonner and the KTL 10-ton tracter, which drives, brakes and steers on all four wheels, should continue to attract notice ; but two new models, which have already been described in this journal, will be worthy of close inspection.

One is the PB3T double-reduction-drive tractor with quickly detachable semi-trailer, meant for loads of 5-7 tons. The other is the GPB3 34-tonuer, having a big engine and being intended for high average speeds.

Finally, the POLL front-drive low-loader will be shown. Just as the KTL tractor is unique for difficult cross-country work, so this front-drive vehicle is peculiarly useful for the handling of heavy machinery, safes, strong-room equipment, etc. The front wheels have 84-in. by 7-in. pneumaties, whilst at the rear is a trailing bogie of four wheels carrying D42 20-in. by 5'-in. twin solid tyres. A 5-ft. loading ramp issometimes fitted in place of the normal tailboard, and a winch is provided at the rear of the driver's seat to assist in loading. There are also detachable screw-type loading jacks.

LEYLAND Stand 64 Improved Passenger Models, Several New Goods Chassis and an 8-litre Oil Engine to be Exhibited

WITHOUT doubt one of the best-known models in the Leyland range is the Titan double-decker, which is to many a familiar object of daily life. One of the latest models with a 51-seater double-deck body will be shawn. The frame is now altered to permit the employment of 9-in. section tyres within the legal. limit for overall width. The springs have been altered at the front to give a greater degree of castor action, whilst the plate stress has been reduced by anchoring each spring at the front end. r!ilie brake drums are now secured by the wheel-retaining nuts, so that their removal is a matter of a few moments. Instead of the semi-floating axle shafts formerly employed, fally floating ones are now specified. These improvements bold good for the range of passenger models,

Turning now to the goods range, there will be one of the new Buffalo 71-ton (gross load) chassis equipped with a hinge-sided body. This chassis has a set-back front axle.

Another important newcomer is the Rhino for 12i• tons (including body) ; it is a six-wheeled goods vehicle with a double-reduction centre axle and a trailing third axle. It will be shown with a tilt van body. One of the new 8-litre Tiger-type oil engines will be installed in this vehicle. This particular unit develops 90 b.h.p. at 2,000 r.p.m. It is of the direct-injection type, employing a 'Bosch 'pump ; there is a cup-form combustion chamber in the head of each piston. Starting is be means of an electric motor and no heater plugs are required. This engine will be shown separately as well as in the Rhino chassis.

Two of the recently introduced Cub models will be shown. Both will have the side-valve six-cylindered engine, which gives an output of 60 b.h.p. at 2,000 r.p.m. The KG3-type which will be exhibited has a gross load capacity of 21 tons. The engine and gearbox are constructed in unit form, and the drive passes to a fully floating overhead-worm-type axle. The braking is unusually efficient, the Lockheed system being employed for the four-wheel brakes, which are operated by pedal, whilst the hand brakes are operated by cables ' Passing through flexible sheaths.

Another Cub, this time of the SKG1-type, is an innovation in that it has forward control. In this ease, the gross load capacity is 24 tons.

On other stands will be shown a Terrier six-wheeled threeway tipper, a Hippo with a boxvan body, a Buffalo with Thompson Brothers tank body and a Cub of the six-wheeled type embodying a Longframe conversion system.

LONGFRAME Stand 138 An Interesting Six-wheeler Extension Avoiding the Use of a Trailing Axle

Oo this stand will be shown examples of the principle of adding to a four-wheeled vehicle a further two wheels of the trailing variety in order to increase the effective payload. The vital feature of the Longframe system is that the trailing wheels are carried upon pivoted arms. These arms are coupled to the rear ends of the springs of the driving axle, and the leverage is such that the driving wheels at all times carry a load which is 25 per cent. in excess of that borne by the trailing wheels. This layout obviates the need for a dead axle, which is apt to complicate the suspension question and somewhat to hinder the free articulation of the trailing wheels.

IVIAUDSLAY Stand 37 Six-cylinder Passenger Vehicles of Advanced Design and Sturdy Construction

THE'

will be lave passenger vehicles staged on this stand, four of them being of the well-known six-cylinder type, whilst the fifth will be a 32-seater single-deck bug incorporating the company's well-known four-eylindered overhead-valve engine. Of the 'six-cylinder models to be shown one is a 31-seater saloon coach with a body by London Lorries, Ltd.; another is a 52-seater double-deck bus with a Dodson body, whilst the remaining two are respectively a 60-seater six-wheeled doable-deck bus with bodywork by " the Brush concern, and a Meteor chassis carrying a Bur lingham coach•body. • •

The six-cylindered engine is of modern design and has .inclined overhead valves operatedby "high" camshafts, the -layout of. the rocker gear being such that the cylinderheads. (of which there are two) can be lifted without disturbing the camshaft or diming ; • at maximum revolution speeds 120 b.h.p: is delivered at the flywheel. The cylinder block incorporates centrifugally east renewable " wet " liners, an arrangement which has permitted the cylinder and crankcase to be cast monobloc in aluminium.

Two separate pressure-fed oil systems are installed, one feeding the main hearings of the crankshaft, the connecting rods, etc., whilst the other conveys the lubricant to the camshafts and the valve rockers.

A single dry-plate clutch and a four-speed gearbox are mounted unitwisc with the engine, the drive being conveyed to the underslung-worm-type rear axle by moans of a divided propeller shaft which is mounted at its centre in a selfaligning ball bearing. The wheelbase of the Meteor is 17 ft. 6 ins, and its track 6 ft. 31 ins. (front) and 5 ft. 9 ins. (rear). It is interesting to note that a Skyhi double-ram jack is included in the standard equipment.

Built largely on identical lines is the Majestic forwardcontrol bus chassis with its 16-ft. 6-in, wheelbase, whilst the 60-seater six-wheeled double-decker has a wheelbase of 16 ft. 2 ins., measured to the centre of the bogie axle.

MERCEDES-BENZ Stand 24 Oil-engined Four-wheelers and Six-wheelers for 6-ton and 12-ton Loads MEIREE models of the four-wheeled L5-type eibengined Mercedes-Benz chassis for loads of about 6 tons will be shown. Each of them has a wheelbase of 16 ft_ P ins. and whilst two have four-speed gearboxes, the third will be equipped with a five-speed box giving it a higher range of speed on stretches of level road. The two four-speed Cetonners will have bodies.

The imposing NK56 rigid six-wheeler for 10-12-ton loads will also be on view. Readers will recall that we published a full report on the performance of this vehicle in our issue dated March 25th, 1920. Since then, however, the engine has been improved in certain details, increasing its power to 85 b.h.p. Just as the L5-type can well carry a five-speed gearbox, so this six-wheeler lends itself favourably to the use of a five-speed box, or the addition of an auxiliary gearbox giving a high range of gears for trunk-road Work. Quite apart from allowing a high average speed, there is the advantage that economy is obtained and the engine is given some respite when level stretches of road occur in the course of exceedingly long runs, such as are the common duty of this class of vehicle. An important feature of the NK56 chassis is that 13.5-in, giant pneumatic tyres are fitted, even to the front wheels.

As for the oil engine, it has behind it a fine name and a long-standing reputation, and it is meticulously builtThe Bosch injection system is employed and starting is effected by 24-volt electric motor.

MORRISC OMMERCIAL Stands 101 and 156 Goods and Passenger Vehicles of Many Types and Sizes MHE recent rapid expansion of the Morris-Commercial

organization will be reflected at Olympia in the comprehensive nature of the vehicles displayed on the COEll■ pany's main stand. No fewer than 22 vehicles will be seen, of which number nine will be concentrated on Stand 101. At the small end of the scale will be a 15-ewt, van which, completely equipped, costs /195. Then there will be a 3-ton baker's van at £245, a 20-cwt. lorry (popularly known as the Middleweight Champion) costing £230, together with an Economy lorry (i263), which has a capacity for 2 tons in a drop-sided body with a platform measuring 11 ft. 6 ins. by 6 ft. 3 ins. In the medium-capacity class operators will be interested in the 50-cwt. Bulk-Ioad eanier, now priced at £29b rs chassis. As its name implies, this model has a large % platform space which has been made possible by including a four-wheeled bogie at the rear ; both the Main axles articulate' about a central dummy axle, but only one is driven. The vehicle to be shown has a wheelbase of 12 ft. 8 ins., giving a platform space of 66 sq. ft.; it might be mentioned, however, that the same type of chassis can also be supplied with a 14-ft. 4-in, wheelbase which provides 77 sq. ft. of platform space, yet it still qualifies for the maximum freightvehicle speed of 30 m.p.h.

Two entirely new vehicles are also to be shown, one taking the form of an Imperial double-deck bus chassis t(1,1,075), whilst the other is the repently introduced Courier 5-ton chassis priced at £725. The passenger chassis embodies the now well-known sixcylinderecl " Wheel-out " engine. An unusually low load-line has been obtained without unduly reducing road clearance, whilst four-wheel brakes, having a total frictional area of no less than 566 sq. ins, and a double-plate clutch providing 656 sq. ins, of contacting surface are features.

The 5-toi3ner is a thoroughly sound engineering job of robust proportions. A four-eylindered engine incorporating the patent "high" camshaft i: and " wheel-out " unit is incorporated In a heavily braced frame. The exhibit will be completed by an ambulance costing £440, and an International Junior taxicab priced at £325.

MORRIS Stands 115 and 132 A Useful Range of Light Vans.

NTO great change is noticed in the 1932 range as compared with that of 1931, but the vans have certainly been improved as regards smartness in their appearance. The Morris light van is meant for express delivery work with loads of 8-10 cwt. It has a four-eylindered, side-valve engine of 1,802 c.c., a sturdy frame and long semi-elliptic springs with recoil dampers. The gearbox is a three-speed unit. As in all Morris products, the equipment is complete and includes a combined dynamo and starter motor and electric lighting. The body has an internal length of 4 ft. 9 ins., a width of 4 ft., and a height of 4 ft. 3 ins., giving a cubic capacity of 78 ft. The body sides and roof offer good publicity space.

The 5-cwt. van has a smaller four-cylindered side-valve engine of 847 c.c., and the body measures 3 ft. 6 ins, in height, is 3 ft. 4 ins, wide and has a length behind the driver's seat of 3 ft. 4 ins., giving a useful capacity of 38 cubic ft., with access by two large doors at the rear. The 5-cwt. van costs £110, the larger van £160, and the Morris-Cowley traveller's saloon, also to be exhibited at Olympia, £195.

In addition to examples of the two vans, bare chassis • svill be available for inspection. D44 PAGEFIELD Stant/ 92 Inclined Mounting for Gardner Engines. and Electric Servo on Large-capacity Six-wheeler

AGOOD many concerns have recently shown an interest in the compression-ignition engine, but few companies have reposed such whole-hearted faith in this type of unit as has Pagefield Commercial Vehicles, Ltd. AT its models employ Gardner engines of the La-type, with various numbers of cylinders. All the chassis are specially designed to take the Gardner engine ; they are not adapted types.

Two models will be exhibited at Olympia. The smaller is a normaldrive 6-tanner and is one of two chassis forming a repeat order by J. Lyons and Co., Ltd. Bodywork will be by Normand Garage, Ltd., and the chassis is equipped with Bendix self-energizing braka all round. Concerning the other model, which is entirely new, there is much of interest. It is a rigid six-wheeler known as the Plantagenet, and is capable of carrying 10-12 tons of pay-load. In this case, the five-eylindered engine drives through a cone clutch to a four-speed gearbox, at the back of which is a supplementary two-speed box. This vehicle gives a platform length of nearly 22 ft., and is equipped throughout with Bendix Duo-Servo brakes.

A particularly noteworthy feature is that the driver's effort is amplified by means of a magnetic servo. When the brake pedal is pressed, a trigger is actuated, which switches on current from the battery to a stationary magnet ring, mounted directly behind

the gearbox. The current energizes a magnet and attraCts a spring-loaded ring coupled to the universal-joint flange. When contact is made between these two parts the stationery magnet ring tends to be dragged around and exerts upon either of the flexible steel ribbons —according to the direction of rotation—a 70-lb. pull ; this is magnified by a three-to-one lever and imparts to the braking system a pull. of 210 lb. Actually, this amount cankbe varied by the setting of a rheostat mounted on the facia board. The current required to operate this device varies from .7 alp. to 1.3 amp.

A Kirkstall three-differential bogie is used, and a noteworthy feature, consequent upon the employment of the cable-operated Bendix brakes, is that rods are abolished.

RALEIGH Stand 151 An Ingenious Three-wheeled Parcelcar Characterized by Marked Manceuvrability

Vie 1. reason of the fact that it is legally classed as a II motorcycle, a three-wheeled vehicle escapes with a tax of £4. This fact naturally reduces considerably the standing charges. To the small tradesman, therefore, the threewheeled Raleigh van offers a marked, advantage.

The exhibits will show the general layout of the chassis and the roominess of the body. The latter is attached to the former by four quarter-elliptic springs. These serve to insulate the load from road shocks, whilst the compressionspring forks give a further degree. of protection from the bumps encountered by the front steerable wheel. A singlecyliiadered, detachable-head engine of the air-cooled variety drives by chain to a three-speed gearbox, in the sprocket body of which is a multi-plate clutchwith an incorporated damper. Final driven is by duplex chain to the rear wheels, the live axle of which incorporates a differential. The brakes take effect on all three wheels.

RANSOMES Stand 27 Four and Six-wheeled TrolleY-Irnses

ONE of the post-war deYelopmeuts in the transport N/industry has been that in connection with the trolleybus, which has found popular favour on account of its silence, mobility and utility as a substitute for the rail-bound tramcar. Amongst the makes which have achieved wide popularity in this country and overseas is the Itansomes, which has been made in single and doubleglecker form. Both will appear at Olympia. The six-wheeler, with a wheelbase of 16 ft. 1 in. and an overall length of 26 ft. 6 ins., is constructed to take a doubledeck body of the covered variety with a seating capacityup to 65 passengers. It has an 80 b.h.p. traction motor with B.T.H. control gear. Retardation on all six wheels is effected by air-pressure brakes, whilst the four driving wheels are affected by hand-operated brakes. The chassis details are lubricated on the Alcyl system.

Complete with a 48-seater, covered-top double-deck body will be the four-wheeled trolley-bus, having a specially low overall height. The complete vehicle has been built by the exhibitor. In this case, also, an 80 b.h.p. traction motor is used. This vehicle has a wheelbase of 15 ft. 3 ins. and an overall length of 25 ft. 5 ins. In each saloon there is space for 24 passengers.

The bodywork exhibits of this concern are dealt with on another page in this issue.

RENAULT Stand 36 New Oil-engined 51-tonner; Light Vehicles with Normal Radiator Position

Tms year the Renault concern is concentrating upon goods models. It will exhibit one heavy type, a 4-tonner with Renault oil engine developing 60 b.h.p., and two light vehicles, the 0S4 30-cwt. chassis and the KZ7 travellers' brougham.

Dealing first with the small machines—each of these has a four-cylindered engine of 2,120 c.c. capacity, with ignition bycil and distributor and six-volt starting 'and lighting set, the -engine and three-speed gearbox forming a unit. The chassis of the 30-cwt. model weighs 23 cwt., the wheelbase being 11 ft. and the track 5 ft. The brougham has a wheelbase Sins, shorter and a track of 4 ft. 9 ins., and is equipped with a smart-looking body, the interior dimensions of which are : length 4 ft. 7 ins., width 4 ft. 2 ins, and height 3 ft. 6 ins. Both vans have the normal radiator mounting before the engine—a new feature for Renaults.

The oil-engined 51--tonner is quite a newcomer to this country. The engine and gearbox form a unit, the former having a bore of 150 mm. and a stroke of 170 mm. Its maximum power (00 b.h.p.) is developed at approximately 1.500 r.p.m., and this gives a top-gear speed of about 33 m.p.h. The chassis itself weighs 34. tons and has a wheelbase of 14 ft. 7 ins. Standard equipment includes a 24-volt starting and lighting set, four-wheel brakes and disc wheels having 38-in. by 8-in. tyres (twin rear tyres).

REO Stand 76 New Four-cylinder and Six-cylinder 35-40-cwt. Chassis. Other Goods and Passenger Models

A,S would be expected by all who read the road-test report appearing in our issue dated August 25th, the new 35-40-cwt. models, which are available with four-cylindered or six-cylindered engines, will be prominent amongst the 'exhibits of the Reo company. The points worthy of note are that the engines have chrome-nickel cylinder blocks so as to resist piston wear, also that large-diameter crankshafts are used with bearings between each pair of cylinders.

Two of the four-cylinder types will be shown, a chassis with 11-ft. 4-in, wheelbase and a drop-side lorry with 13-ft. 4-in, wheelbase, the useful platform space measuring 11 ft. 6 ins. long. A shortaix-cylinder type will be shown equipped with a hand-tipper.

There will probably be seen a new 20-passenger chassis suitable for coach or bus operation anddesigned in every way to meet the requirements of the Ministry of Transport, its wheelbase being 13 ft. 9 ins.

The new model-GC chassis, the capacity of which has been increased from 3-i tous to 4 tons, will also be shown. Those familiar with the old 3f-tonner will notice that the steering has been much improved.

The type-GD chassis which has a 12-ft. wheelbase and is intended for use as a tractor unit, will be shown equipped as an articulated six-wheeler. In this form it is calculated to carry pay-loads of 7-8 tons, and the platform length is 20 ft. The display is to be completed by a 26-seater service bus having the GE-type chassis with six-cylinclered engine and a wheelbase of 14 ft. 11 ins.

ROVER Stand 69 A 12 h.p. Six-cylinder Ambulance and a Remarkable Rear-engined Van

ALTHOUGH a comparative newcomer to the commercial. motor industry the Rover concern has lost no time in setting out a range of light vehicles which are adaptations

of the concern's private cars, suitable chassis modifications being made. Of particular interest will be a Scarab 5-cwt.

light delivery van which has a V-twin-cylindered air-cooled engine of 75 mm. bore and 95 mm. stroke (840 c.c.) and, with an enclosed body by Cross and Ellis, Ltd., sells for

£99 10s. The layout of the transmission, although unusual, is thoroughly sound. The engine, clutch, gearbox and final reduction gearing are built unitwise in an aluminium casing which is carried on the main frame; radius arms emerge from the engine body and control the movement of large-diameter spiral springs.

An ambulance body mounted. on a 12.95 h.p. six-cylindered chassis will also be shown.

Priced at £151 and £160 respectively will be two 10-25 h.p. vehicles, the former taking the form of a drop-sided lorry, whilst the latter is a van. Each machine has a capacity for 10 cwt. of pay-load, the wheelbase and track dimensions of 8 ft. 8 ins. and 4 ft. 2 ins. giving a useful loading space.

New Trailing-axle Rigid Six-wheeler and Other Models T "'new models, representing different types of multiwheeler introduced recently by Scammell Lorries, Ltd., • will be prominent. The first is the articulated bogie-type eight-wheeler, in which the carrier bogie has four single wheels and permits the fitting of 13.5-in. by 20-in, lowpressure tyres; this will be seen with a contractor's body. The 17-tonner can carry 14 tong within the legal limit.

The other new model is the 12-ton rigid six-wheeler having a trailing axle. It is in no way intended to supersede the articulated type which has made the Scammell name famous. There is, however, a definite demand for six-wheelers of the rigid type, and that is why the new model has been introduced. The forward pair of bogie wheels is driven by duplex

chains, whilst the rear axle is undriven. Again 13.5-in. tyres are fitted. This machine has a body frame measuring 22 ft. long and the chassis weighs approximately 51 tons.

A frameless tanker will be seen which is something of a novelty in that the tank is made of aluminium, a material which has not, to our knowledge, hitherto been used for frameless tanks. The tank shown is a product of Thompson Bros. (Bilston), Ltd., of Bilston, Staffs, and has a capacity of 3,000 gallons. The fourth exhibit is one of the four:wheelers, capable of carrying the maximum legal load.

On Stand 130 of the collective chassis exhibit in the Empire Hall will be seen one of the Pioneer overseas-type rigid six-wheeler chassis. In appearance this somewhat resembles the new trailing-axle rigid six-wheeler shown on Stand 32, but, of coarse, the drive is transmitted through all four rear wheels through a chain of gears encased in a

pivoting beam on each side which permits remarkable articulation when the vehicle is traversing rough ground. On Sta.nd 130 there will be also a 5-7-ton trailer chassis of standard Scammell type.

It should be pointed out that all Seammell machines have the company's standard 80 b,h.p. four-cylindered overheadvalve engine.

SENTINEL Stand 114 Five Steam Wagons to be Shown, including the New Shaft-driven Model

'ALTHOUGH steam-engined vehicles will be shown on

various stands at Olympia, the Sentinel exhibit will be one of two solely devoted to the display of steam vehicles. This concern has kept pace with the times and evolved new designs, meeting legal requirements as regards weight restrictions, etc., whilst developing, at the same time, the particular advantages offered by the external-combustion form of prime mover.

In the National Hall will be found five steamers, one of which is a 10-12-ton double-geared rigid six,wheeler.• This is a new model in the Sentinel range in that it has shaft drive to a fully compensated double-reduction bogie, all four wheels of which are driven. The engine of this machine gives 120 bh,p. and is of the double high pressure type, with which a 'two-speed gearhox is integrally mounted.. The boiler is of the vertical water-tube type with a superheater. All wheels 'are shod with. 40-in. pneumatic 'tyres and allsix wheels are braked. The body of this exhibit is 18 ft: long. • Having chain drive, will be a 10-ton DG6 platforth wagon on pneumatic tyres. In this case the four wheels of the bogie are braked by manual effort or with steam assistance. The engine and boiler are of the same general design as those of the shaftdriven wagon first described.

Another vehicle of the DG6 chain-driven type, and Intended for a 10-ton pay-load, will have a three-way tipping body. • The effort for load discharge is obtained from the water pump of the wagon, The tipping body is 14 ft. Tins.

long and has 32-in, hinged sides. • Turning to the four-wheeled exhibits, we understand that a 6-7-ton DG4 platform vehicle will be shown. This is of the chain-driven type with 40-in. by 9-in, pneumatic tyres and hand and foot-operated brakes taking effect on the drums of the rear wheels. The engine and boiler are similar in general design to those employed on the six-wheeled wagons.

The DG4T model, that is, the 6-tonner for three-way tipping and equipped with pneumatic tyres, will also be shown. This will have a 13-ft, 6-in, body with 28-in, sides.

All of the five, exhibits will have pneumatic-tyre equipment; solids can still be specified where preferred.

STIEFFLEX Stand 106 Two Trailing-axle Six-wheelers with Improved Brake Gear

. A LTHOUGH the concern in question markets both four./-1 wheeled and six-wheeled vehicles, it has been decided to exhibit only examples of the last-named category. One will have full forward control, whilst the other will be of the type having the driver behind the engine. Recent changes consist principally of alterations to the brake-operating mechanism.

From the pedal the effort passes to a Marelli vacuum servo, which amplifies the output and passes it through 046

compensators, which distribute the effort between the brakes of the driving and trailing axles, and between the righthand and left-hand brakes. Owing to the layout of the various levers, it is provided that the brakes OR the trailing axle come into operation slightly in advance of those on the driven axle.

In general, both chassis have similar layouts. A. foureylinciered Dorman engine drives through a separately mounted four-speed gearbox and an open propeller shaft to an axle with fully floating shafts and an overhead worm.

SINGER Stand 103 New 35-cwt. Lorry and Seven Other Vehicles Ranging from 5-ewt. to 45-cwt. Capacity

A. WIDE range of vehicles will be shown on this stand; they will include a new 35-cwt. Prosperity lorry. Equipped with a six-cylindered engine actually developing 65 b.h.p. at 3,600 .r.p.m., the new vehicle should have a lively, performance. A short wheelbase of 10 ft. 6 ins, ensures geed manoeuvrability in a vehicle having a useful body length of 9 ft. 6 ins. A four-speed gearbox, fully floating rear axle, four-wheel brakes, 6-in. by 20-in, pneumatic tyres with twins at the rear, Merles steering, tapered-roller bearings to all road wheels and grouped chassis lubrication are prominent features.

Of the three 5-ewe Junior models to be shown, two will be vans and the other exhibit a chassis. Although of 8 h.p. nominal rating the four-cylindered engine develops something like 20 h.p. at maximum revolution speeds. Certain improve ments have been made in the 10-cwt. van; changes in body design have resulted in more pleasing lines and the loading space has been increased by 7 per cent.

The six-cylinder 25-ewt. van to be exhibited has been

improved recently in certain details. Four-wheel brakes operate in 13-in, drums on the front wheels and in 15-in. drums on the rear wheels. Interially the body measures 7 ft. 6 ins, in length and 5 ft. 4 ins, in width, whilst the height is 4 ft. 6 ins.

Using similar main components, the 2-ton and 45-c-wt. models differ chiefly in respect of loading space, the wheelbases being respectively 11 ft. 1 ins. and 12 ft. 9 ins. These dimensions give a useful body space of 9 ft. 2i ins, in the case of the 2-ton model and 10 ft. 10 ins. in the larger type. The engine specification includes a five-bearing crankshaft and a camshaft driven by an easily adjustable tripleroller chain, operating overhead valves through the medium of push rods. '4 Four forward speeds are provided by the geasbox and the rear title has fully floating half-shafts with a worm final drive.

SLINGSBY Stand 146 Useful Battery-electric and Petrol-engined Industrial Trucks and Trailers

AMONGST a wide range of appliances of interest to those concerned, in the purchase of industrial transport machines, there will be examples of the Slingsby-Brett petrolengined industrial truck and a low-platform battery-electric truck with worm drive to the front wheels. The load capacity is about 36 cwt.

Dealing first with the petrol-engined models, one will be of the plain-platform type. In this machine the engine and transmission set are carried directly above the single front wheel which takes the drive. As the driver can turn the front wheel through rather more than 180 degrees, exceptional manceuvrability is provided. This model has an overall length of 8 ft. 6 ins., a turning radius of only 5 ft. 6 ins, and it can carry 11 tons on the platform.

The other petrol-engined machine will be of the elevatingplatform type. Again the carrying capacity is 30 cwt, and the elevation is effected by means of an hydraulic jack. The platform can be lifted to a height of 16f ins.

A battery-electric model capable of carrying 4,000 lb. will also be shown.

STEWART DERBY Stand 98 Stewart 2-tonners and New Derby Front-drive 10-ewt. Van

MWO models of the Stewart 2-tonner will represent the range of chassis of that mete. The six-cylinder model, having a wheelbase of 14 ft. 8 ins., is to be displayed in chassis form equipped with a cab as made at the Stewart works. The tyre size is 6.50 ins. by 20 ins. (twin rear). The engine of this model develops between 65 b.h.p. and 70 b.h.p., so that it is quite a high-powered chassis.

The other example to be shown will be a four-cylinder 2-tonner of 11-ft. 8-in. wheelbase. This has the same tyre equipment as the longer chassis, and the engine is practically as powerful, being claimed to develop 65 b.h.p. A feature of Stewart 2-tonnera is that they have fully floating back axles.

Morgan Hastings, Ltd., has a surprise in store for visitors in the form of the Derby front-wheel-drive, forward-control, 10-cwt. van. This is, in its present form, a modification of the Derby front-drive motorcar which was seen a week• or two back at the Olympia Motor Show. It has a wheelbase of 9 ft, 4 ins., and a four-cylindered engine of 1,100 c.c. By reason of the gearbox being mounted before the engine, conversion to forward control has offered no.,serious difficulties, and the rather extraordinary result is that a body space behind the driver nearly 9 ft. long is obtained, the interior width being about 4 ft. 6 ins., and the interior height about 6 ft. The floor height is only about 15 ins.

STUDEBAKER PIERCE-ARROW Stand 116 Both Chassis Amended to Give Larger Pay-load

SINCE their introduction to the British Market, Studs-. baker Pierce-Arrow chassis have been recognized as of sturdy design and liberally proportioned to withstand the loads for which they have been rated. In order to increase' their range of utility, it has been decided to change the design in detail so as to permit larger pay-loads. The result is that the two types of .chassis now offered are intended. for 21 tons and 2 tons. Two of the former type will, be shown—one as a chassis and the other with a coachbuilt cab and tipping body with an hydraulic mechanism.

The other 21-tonner will have a wheelbase of 13 ft. 4 ins. and be shown as a bare chassis. The engine has six cylinders and the output is 70 b.h.p. at 3,200 r.p.m. The engine and gearbox are coupled to form a unit and four-point mounted in the frame. In addition to the ordinary semi-elliptic springs, there are auxiliary groups which come into contact with brackets on the frame.

Thirdly, there will be an example of the 2-tonner, shown with a special side-loading Luton van body and with a wheelbase of 13 ft. 4 ins. The price of the complete machine is £435.

THORNYCROFT Stands 62 and 132 Examples of a Completely Revised Range Include New Passenger Models of Particular Interest

nCCUPYING an almost central position on an island site Min the Grand Hall will be half a dozen examples of the latest Thornycroft range, which has been revised and extended so that it now includes some 40 types of chassis. The complete passenger range for 1932 is of a new type. Dealing first with the passenger machines there will be a 32-seater of the Cygnet type with a front-entrance omnibus body. This machine has a six-cylindered engine which develops 85 b.h.p. at 1,500 r.p.m., whilst the governed speed is 2,200 r.p.m. Mounted as a unit with the engine is a four-speed gearbox with a remote-type control.

Another interesting new model which will be shown is the Daring double-decker. This makes use of a similar type of engine to that employed in the CD model. The front

axle is of the built-up box type, which gives a greater strength than is possible with a solid axle. In this design the front-wheel brakes have been laid out to give the maximum possible capacity which can be arranged in the space available.

In the case of the rear axle a cast-steel, box-fortes member is used. The shafts are of the semi-floating type in order to give widely spaced bearings. The transmission is off-set in accordance with modern practice, and maintenance engineers will find a pleasing feature in the ready detachability of the engine.

Among the goods machines will be a 2-tonner of the A10 Forward type, carrying a fixed-sided lorry body. This chassis is now known as the Bulldog. A slightly larger machine will be that termed the Speedy, which is intended to carry a 2i-ton pi'-load. This has a six-eylindered engine, and a novel feature of the exhibit will be the movable floor. The largest four-wheeled goods machine will be a Jupiter with a 14-ft. 6-in. wheelbase. in this case the front axle is set back behind the engine.

Finally, it is hoped to show a six-wheeled OD model for 11 tons. This bears the name of Colossus, and will reveal the Thornycroft 100 b.h.p. six-cylindered oil engine. This power unit is of the direct-injection type, the atomizers being mounted horizontally and the delivery of the spray of fuel is across the tops of the piston heads. Starting is by means of an electric motor. The capacity is 10i litres, The engine has overhead valves inclined at 15 degrees to each other. No heater plugs are required, and the engine starts on full compression.

Among the collective exhibit of chassis to be staged in the Empire Hall will be a 6-tonner of the rigid six-wheeled type. There will also be an example of the new Daring double-deck chassis, a special feature of which is the boxform construetion adopted for both front and rear axles ; the spring mountings are interesting. TROJAN . Stand 108 A Novel Centrifugal Clutch Embodied in the New

12-cwt. Van. All Models with Two-stroke-cycle Engines MTECHANICAL features of unusual, but genuinely prac-1.Y.Ltical design have always been expected in connection with Trojan vehicles. This year the chief innovation consists of the employment of an automatic clutch of the centrifugal type. It is purely mechanical and enables the van to be driven on top gear from a standing start, whilst the gear changes are perfectly quiet and jerky acceleration is prevented. When the engine is ticking over any gear may be engaged without depressing the clutch pedal. Above about 10 m.p.h. on top gear the clutch automatically locks This unique feature will be embodied in the new 12-cwt. van. The nOne used, of course, is the two-stroke-cycle fourcylindered Trojan, with a capacity of 1,488 cc. and developing 14 b.h.p. at the unusually low speed of 1,350 r.p.m. The epicyclic gearbox gives three forward speeds and one reverse. This new model is priced at nso. Also on the stand will be a standard 10-ewt. van with a loading capacity of 90 cubic ft., and one of the Victory models with a two-speed gearbox and a body affording a loading space of 102 cubic ft.

ALTHOUGH the chassis and vehicles to be exhibited by P.S. Motors, Ltd., will in three cases out of four be new to the general public, they are by no means untried machines, as they have been available for several months. An old favourite, which, by reason of its sound design and economy in operation holds just as high a place as ever in the public esteem, will be the B.10.A.2 type Express shown as a single-deck bus. The body of this exhibit will be a 32-seater bus by Strachans (Acton), Ltd.

A chassis of recent introduction will be the single-decker type with a six-cylindered 109 b.h.p. engine. This model is produced to carry a load of 36 passengers, with a body weighing 2 tons. In the case of the exhibit, however, seats are provided for 30 passengers in the Beadle coachwork. A separately mounted gearbox is employed, and the transmission is of the open type.

The third passenger machine will be a double-decker embodying the same form of six-cylindered engine. This example will be shown without a body, and has a wheelbase of 16 ft. 1 in. The height of the frame, laden, is 2 ft., and the overall length 26 ft. The body allowance on this model is 24 tons, and it is intended to carry 52 passengers.

The engine is carried in a Sub-frame. In accordance with modern practice the transmission is off-set towards the near side. Between the clutch and the gearbox the universal joints are of the flexible-disc type, whilst mechanical couplings are used for the shaft leading from the centre bearing to the underslung-worm axle.

Finally, there will be an example of the recently introDIS duced 4-ton goods chassis. This has the popular Express engine, forward control, a 12-ft. 8-in. wheelbase, and a simple but strong frame. Two oil-eng,ined chassis will be shown in the collective display on Stand 113. Both employ the compression-ignition engine of Gardner manufacture. One chassis will be a 4-ton goods mode), whilst the other will be a forwardcontrol passenger type, designed for bodies with a seating capacity for 32 persons. • T.TA. Stand 145 Six-wheeler Conversion and New Semi trailer Unit

OFINE of the pioneers amongst companies specializing in conversion of four-wheelers to rigid, trailing-axle six-wheelers is the Truck and Tractor Appliance Co. (Manchester), Ltd., Trafford Park, Manchester. The company will exhibit a Chevrolet 30-cwt. chassis converted by the T.T.A system. A heavy semi-elliptic spring is fixed to the frame on each side and below it is pivoted a rocking beam of cast steel, at the ends of which are spherical bearings carrying the road-wheel axles. The brakes are operated by a Dewandre vacuum servo.

With the Chevrolet 30-cwt. chassis the available body space aft of the cab is 11 ft., whilst for the Bedford longwheelbase 2-tonner it is 13 ft 2 ins.

The same company will be showing a new, semi-trailer

for converting chassis hate articulated six-wheelers. It will be seen in conjunction with a Willys Manchester 35cwt. chassis, and is made for those who require the additional load space of the six-wheeler coupled with the facility of being able to detach the motive unit from the trailer. Steerable front jockey wheels are provided for use when the trailer is left without the tractor. The coupling between tractor and trailer is entirely automatic. Dewandre vacuum brakes are fitted, with a coupling similar to that used on railway trains.

A similar outfit incorporating the Reo 35-40-cwt, sixcylinder chassis and a trailer with an arched frame will also be seen on this stand.

UNIC Stand 96 Revised Models including Two Chassis, Two Vans and a Taxicab

FOR the 1932 season it has been found necessary only to modify existing types of Unic chassis in order to bring them right up to date. One of the principal points is that really large low-pressure tyres are now standard equipment, whilst a new form of radiator mounting has been adopted in order to give the required flexibility. On certain of the models a new feature is the transverse ribbing of the brake drums.

The actual exhibits will number five. The first is a K.F.1type taxicab with a fie-seater body. With a delivery-van body will be an L.11.D chassis, which has a gross-load capacity of 27i cwt. The four-cylindered 40 b.h.p. engine is three-point mounted in the frame. Thirdly, there will be an M.9.A.2 chassis. This has a gross load capacity of 2 tons. Incidentally, the wheelbase dimensions of several models in this range have been lengthened.

Another delivery van will be mounted on an M.9.0.2 model with a 13-ft. wheelbase. Including the body, the load capacity is 24 tons. The fifth exhibit, and the largest, will be an M.8.0.2 chassis shown without bodywork. This has underslung rear springs, thus giving a low load line and making the chassis especially suitable for passenger work or as a basis for livestock carriers. It has a gross load capacity of 31 tons. VICHERS-ARMSTRONGS Stand 150 Two Novel and Ingenious Track-laying Machines

TEE exhibit of this celebrated engineering concern will probably be unique in that the machines to be shown are both of the track-laying type. One is a light 30-cwt. tractor-lorry which can haul a similar burden on a tracklaying trailer, whilst the other is a 6i-ton lorry which is Of the double half-track type.

In the case of the Carden-Loyd tractor-lorry the frame takes the form of a punt in which the six-cylindered engine, and gearbox are mounted on the off side, and the petrol tank on the near side, At the front is the driven " axle," which embodies a clutch on each side and a brake on each. side. The operation of these constitutes the steering control. The track is of the all-metal type. An important poiut is that the driving sprockets being raised above the ground level, are isolated from shocks.

The larger machine, known as the VickersArmstrongs cross-country lorry, has a front axle which is free partially to rotate for steering purposes and can rock from side to side. The four dual-tyredwheels carry all-metal tracks and suspension is by four inverted semi elliptic springs on each side. Steering is effected by the

operation of Lockheed hydraulic, ;brakes which may be employed to retard the inner track on any turn.

The 80 b.h.p. air-cooled four-cylindered engine drives through a five-speed gearbox to the track sprockets in the centre of the frame. The track passes over a special articulating frame. This machine on its normal tracks imposes upon the ground a pressure of 15 lb. per sq. in. This can be cut down to 6 lb. per sq. in. when special swamp plates are bolted to lugs on the standard track. This novel vehicle will climb 1 in 5 with a full load, can pass through 3 ft. of water, and turn in a circle of 30-ft. radius. It will also haul a trailer.

WILLIS Stands 39 and 131 A New All-British Forward-control 2-tonner and other Models of the Lighter Class

THE principal item of interest will be an all-British 2-ton chassis in the well-known Manchester range. Equipped for forward control, the new vehicle gives a large amount of body space, despite a moderate wheelbase. The engine has four cylinders of 90 mm. bore and 130 mm. stroke. The transmission provides four forward speeds which, thanks to a light-acting single-plate clutch., give an easy gear change.

Other Manchester models include a 21-tonner and a 2-ton vehicle, both of which have the normal control position. The former, however, has a 13-ft. wheelbase, whilst the equivalent dimension in the latter type is 10 ft. 6 ins. Although planned on identical lines, thepower units differ somewhat in size, the larger vehicle being equipped with an engine having four cylinders of 4 ins, bore with a piston stroke of 5 ins., whilst the 2-tonner has cylinders of 3i ins. bore and 5 ins, piston stroke. These models are equipped with four-speed gearboxes, servo brakes, etc., and sell at moderate prices.

A 30-35-cwt. model with a smaller side-valve engine and a three-speed gearbox also will be shown, this having a 10-ft. 6-in. wheelbase. Finally, examples of the recently introduced Six-Thirty chassis will be on view..

YORKSHIRE Stand so

A Rigid Six-wheeled Steamer with Double Propeller Shafts

ASINGLE example of the W.J. type, light six-wheeled chassis will be shown, in this case with a three-way tipping gear. The boiler is of the double-ended locomotive type with a circular firebox, and the steam pressure is 250 lb. per sq. in. Superheaters are employed, and the output of the two-cylindered, vertical, compound engine is 100 b.h.p. A double high-pressure intercepting valve is used to give the

added power required for tackling steep gradients. The primary propeller shaft is single, but a spur-gear distribution set transmits the power through two propeller shafts—one to each of the two live axles. This system means that there is less angularity in the shafts by reason of their greater length. The overhead-worm axles carry four brake shoes per wheel, each set of four being operated by foot or hand. The frame has specially reinforced flanges. '
