THE SHOW: What Y

Will See at Earls Court

ONLY one new model will appear among the numerous exhibits to be found on the A.E.C. stand. This is the Mammoth Minor, which was introduced to give operators a pay-load capacity midway between that of the two-axle vehicle, with its limit of Ti-8 tons, and that of the 13-13i-ton six-wheeler.

An interesting exhibit will be an A.E.C.-English Electric six-wheeled 39-seater central-entrance trolleybus with a Craven's body. This incorporates a novel arrangement of series dynamic Patent electrical-control equipment housed in a compartment at the rear, where contactors, control gear and resistances are readily accessible through doors and can, if necessary, be removed as a unit. Power is provided by an English Electric 100 b.h.p.. motor with series dynamic control, permitting speeds up to 40 m.p.h. and a hign degree of acceleration.

Other passenger vehicles on view will be examples of the well-tried • Regent double-decker and Regal single-decker. The Roe 56-seater body of the Regent oiler has been designed by Mr. Vane Morland, Leeds Corporation's transport manager, and represents a departure from the orthodox in double-decker layout. The Regale will comprise a 34-seater oil-engined bus and a Mark II oil-engined chassis

c32

"P3-7i-tonner, a noteworthy feature of which is the employment of unit construction for engine and gearbox, a departure from the maker's previous practice for heavy models. The valves of the four-cylindered petrol engine are operated by push-rods and •rockers from a camshaft carried high up on the off side of the cylinder block. The two cylinder heads can he removed without disturbing the camshaft drive or altering the valve timing. The chassis will be shown with a platform body by the North London Engineering Co., to the order of the Gas Light and Coke

Co. .

Another new model will be the 12-13-ton six-wheeler; to be shown in chassis form.

The smallest goods model will be a 30-40-cwt. forward • control Luton-type van with body by Glover, Webb and Liversidge, Ltd., to the order of Hampton and Sons, Ltd. The chassis incorporates a 23-65 h.p. four-cylindered engine, instead of the standard 20-45 h.p. unit. The popular 30 m.p.h. 5i-torkner—in this case with a platform body by the London Motor Construction Co.—Will doubtless receive close attention. .

The well-tried 6-7d-thriller will be exhibited as a platform lorry for the L.M.S. Railway, and incorporating a Gardner 4LW oil engine.

On the passenger side there will be exhibited a Valkyrie coach with a Gardner 6LW oil engine and a five-speed overdrive gearbox. The 32-seater body is by Duple Bodies and Motors, Ltd. A Duple 26-seater oody will also be seen on a Victor chassis having a four-cylindered 23-65 h.p. petrol engine.—Albion Motors, Ltd., Scotstoun, Glasgow.

AAXIMUM-LOAD vehicles of • 1V1two types will be featured by

Atkinson Lorries (1933), Ltd. One will be model L.744, a 7-ton

four-wheeler with a platform body • 17 ft. 6 ins. long. The vehicle, which has a wheelbase of 13 ft. 2 ins, and is mounted on 36 by 8 tyres, is equipped with a Gardner 4LW oil engine. Features of the design are clean layout and attention to low unladen weight, which, incidentally, is under 4 tons.

The other model will be an

L.1586 15-ton eight-wheeler in chassis form, with a Gardnei 6LW oil engine. The wheelbase of 18 ft. affords a body length of 24 ft. The Kirkstall double-drive bogie incorporates a third differential. The complete vehicle weighs 61) tons.—Atkinson Lorries (1933), Ltd., Marsh Lane, Preston.

SMART light delivery vans in three load capacities will L./figure on the Austin stand. The largest is a 7-10.cwt. model having a 1.535-litre engine. The body is 5 ft. 6 ins. long, 4 ft. 8 ins, wide and 3 ft. 11 ins, high, affording a capacity (with one bucket seat) of 88 cubic ft. The fourspeed gearbox has synchromesh engagement for second. third and top ratios, and the drive is transmitted through a single-plate clutch with a flexible centre—refinements exemplifying modern tendencies.

Next in the downward scale of sizes is the 6-S-cwt. 10 h.p. van, which affords a pay-load-capacity of 83 cubic ft. Finally, there is the handy little 5-cwt. model, which has a 747.5 c.c. engine. Even this model has a four-speed gearbox with synchromesh engagement for second, third and top ratios.—Austin Motor Co., Ltd., Longbridge Works, Birmingham.

34 ITS smart appearanca attracted considerable attention to I the Beardmore taxicab at the Commercial Motor Show of 1935. This year, five examples of the improved Mark VI model are to be shown, one in chassis form and the remain der as complete vehicles. The chassis incorporates a 13.9 h.p. engine and four-speed gearbox, all ratios being on the synchromesh principle. The specification includes an air-cooled, single-plate clutch, worm final drive and Girling brakes.

The complete vehicles to be shown will comprise two three-quarter landaulets and a couple of single landaulets, all being four-seaters.—Beardmore Motors, Ltd., 112, Great Portland Street, London, W.1.

La XAMPLES of the full range will be on view and one of the most outstanding will be the Vista 25-seater luxury coach. This has a handsome body of composite construction, in vlthich an ash frame, steel panels and non-rusting alloys are used. Equipment includes a Sunsaloon head, frameless full-drop windows and Dunlopillo seat cushioning.

Other passenger machines will be the Bedford de luxe ambulance and the Vauxhall S-type 25 h.p. ambulance. Features of the former are specially soft springing, lowpressure tyres and hydraulic shock absorbers. With regard to the Vauxhall ambulance, noteworthy features are the sun visors, window blinds and guard rails, Lomas fourmovement stretcher and illuminated accident sign.

Coming now to the goods machines the display includes the popular 8-cwt. van, which has 75 cubic ft. of loading space and a 12 h.p. engine and synchromesh gearbox; the 12-cwt. van, giving a capacity of 107 cubic ft., also equipped with synchromesh; two models of the 30-cwt. chassis, a van and a drop-sided lorry; two 2-tonners, one a long-wheelbase lorry with drop sides, and the other a handoperated tipper: and, finally, a pair of Bedford 3-tonners, one equipped with hydraulic tipping gear and the other a typical drop-sided lorry. Attractive features of the lastnamed vehicle are its 14-ft. body, its low weight complete— only 48i cwt.—and the use of two-piece body sides and detachable body pillars.—Vauxhall Motors, Ltd., Luton.

PASSENGER vehicles will hold sole sway on the Bristol stand. The K and L models will be shown in chassis and complete forms. The K type is for double-deck coach work, and the complete vehicle will be seen with a 53-seater rear-entrance body by Eastern Coach Works, Ltd., to the order of the West Yorkshire Road Car Co., Ltd. The specification includes a Gardner 5LW five-cylindered oil engine -giving 85 b.h.p. at 1,700 r.p.m. Other proprietary components in the make-up include Layrub and HardySpicer propeller shafts, and triple Dewandre servo brakes.

The L model as a complete vehicle will have a 32-seater front-entrance body, also by Eastern Coach Works, Ltd., built to B.E.F. specification.—Bristol Tramways and Carriage Co., Ltd., Tramways Centre, Bristol.

TWO of the main Brockhouse exhibits to be found among a selection of semi-trailers and trailers will be a Kwikfiks 6-ton attachment with a drop-sided body, and a Pullmore 8-ton semi-trailer attachment having a front headboard and a chock-rail body. The former will be coupled to a Guy Ant tractive unit and the latter to a Cornmer LN5 tractor.

The trailer exhibits will include a 6-8-ton four-wheeler with a ball-bearing turntable, a torsion-bar trailer (quantities of which have been supplied to Government departments), a twin-bogie pole unit, and a 30-cwt. two-wheeler incorporating a patent castor wheel and other features. Of interest to fire authorities will be a 350-500-gallon trailer pump, of the type that, during the past few years, has acquired a position of considerable popularity in many spheres.—J. Brockhouse and Co., Ltd., Hill Top, . West Bromwich.

STREAMLINED from scuttle to the rear of ,the semitrailer (made possible by virtue of the Carrimore patented automatic retractor), the Bedford-Carrimore 1,200-cubic ft. furniture van to be seen on this stand will attract widespread attention. The retrattor, gear enables the space between the back of the driver's cab and the front of the semi-trailer to be considerably reduced, a clearance of 6 ins. ensuring safety under all conditions.

Another` interesting exhibit will be a 6-ton six-wheeler with four wheels in line the weight of the outfit, including c35 the Commer tractor unit, being under 4 tons. The DodgeCarrimore 10-ton six-wheeler to he shown also weighs under 4 tons. A semi-trailer for carrying cable drums will be shown attached to a Karrier Cob tractor.

The trailer part of the company's activities will be represented by a 5-6-ton four-wheeler with Bendix brakes operating on all wheels, and incorporating an automatic breakaway device.—Carrimore Six Wheeler;, Ltd., High Road, Finchley, London, N.12.

WITHOUT doubt a feature of the Show will be the VY number of so-called utility machines of the shootingbrake type. On this stand there will be two, one of which is an entirely new model of bigger capacity and power than the now familiar Commer utility vehicle based on the 8 cwt. chassis. A new utility tender is of 14 h.p. and accommodates eight passengers. Perhaps its most noteworthy technical feature is that the front wheels are independently sprung. In addition, the frame is of the box-section type, so that, on both accounts, it is well

equipped for traversing rough ground. '

Other examples of the popular light range will include a 15-cwt. van, two types of the 20-25-cwt. model—one a forward-control van and the other a normal-control vehicle adapted for mineral water transport—and a 1 i-2-ton dropsided lorry.

In the larger classes there will be three specimens each of the 2-3-ton and 4-5-ton models. In the latter case a bare forward-control chassis will be on view, from an examination of which it will be possible to see how modern constructional practices enable a big load to he carried without loss of strength, whilst the unladen weight of 24 tons is not exceeded.—Commer Cars, Ltd., Luton, Beds.

Q1X exhibits will find a place on this stand. Undoubtedly he most imposing will be a 40-ton eight-wheeled machinery trailer, 30 ft. 9 ins, long overall and 8 ft. wide. The main platform area is 16 ft. long, whilst a foredeck affords a further 6 ft. 10 ins, of length. The minimum loading height is 1 ft. 104 ins. The front four wheels are equipped with 720 by 180 twin solid-rubber tyres and conform with ground contour by the use of a patent pivoting spring gear. The four rear wheels are fitted in oscillating beams. the assembly being detachable.

Springing is a special feature of the 10-ton all-steel sixwheeled low-loading trailer to be exhibited. More specialized in its application is an all-steel sixwheeled cross-country log wagon for negotiating swampy ground. The four rear wheels carry 10.50 by 13 tyres, and the front wheels 32 by 6 equipment. Two semi-trailers, one for use behind a Scammell mechanical horse, and the other a cranked-frame 6-tonner . coupled to a Studebaker 4-ton .tractor unit, will be seen.— 'Cranes (Dereham)r, Ltd., South Green Works, Dereham, Norfolk.

MTAKING its first public appearance, the new Crossley 1V15-ton petrol-engined goods chassis, weighing under 24 tons unladen with cab and body, will undoubtedly excite more than usual interest. This machine has a four-cylin

dered 24 h.p. engine similar in its general characteristics to those supplied to Government services.

An unusual exhibit will be a six-wheeled tender for dealing with accidents at aerodromes. The use of a petrol engine developing approximately 100 b.h.p. affords a road speed of 60 m.p.h. The gearbox gives four forward speeds and an auxiliary unit affords a further range of four lower ratios. The chassis carries an airfoana pump driven by a power take-off from the gearbox, and capable of delivering 1,000-1,600 g.p.m.

The exhibit will be completed by four passenger models, two being oilers and the others six-wheeled trolleybuses. One of the oilers will be shown in chassis form, whilst the other will be seen carrying a 54"-seater metal body of patented construction. The .trolleybuses will also be seen in chassis and complete forms; the latter will be shown with a 68-seater metal. body having a special type of concealed

gantry. The' troReybuses incorporate MetrOpolitan-Vickers electrical equipment, the compound wound regenerative-control motor giving 90 b.h.p.

Provision is made for manceuVring these vehicles independently of the line supply. For this pur pose two 30-volt batteries are carried. They are connected in parallel for lighting and charging and in series for driving.—Crossley Motors, Ltd., Gorton, Manchester.

rIVE models have been selected by the Daimler Co.,

Ltd., for exhibition. The well-known C.O.G.6 type, which has a Gardner five-cylindered oil engineof 7.046 litres and fluid flywheel transniission incorporating a Wilson fourspeed preselective gearbox, will be seen in three forms. A stripped chassis Will be suppkmelated by a double-decker with Metropolitan-Cammell-Weymann 54-seater metal body built far Birmingham Corporation, and a Duple-bodied 85seater luxury coach for United Seryices, Ltd:, Upton:

The trolleybus; aconipamtively recent innovation for the Daimler.concern, will be seen as a four-wheeled chassis for double-deck bodywork,. and as a complete six-wheeler with a 64-68-seater_body.by Messrs.; Harkness Coach Works. The stripped. chassis will incorporate a Metropolitan-Vickers 85 b.b.p.; regulated-field motor, 'and the six-wheeled bus a 90 b.h.p. motor of the same Make. In each case the control

gear is of the electro-magnetic contactor type, arranged for mounting in the cab. Westinghouse pressure air brakes take effect on all wheels, the six-wheeler also having regenerative and rheostatic braking.—The Daimler Co., Ltd., Coventry.

Tw'Dnew models, the Max forward-control four-cylinder oiler, and the Ajax normal-control 2i-tortner, will appear among the 10 exhibits on the Dennis stand. The Max has a 6.5-litre engine and five-speed overdrive gearbox mounted

in a straight frame. Rubber and torsion-bar suspensioia is a notable feature. The Ajax has a 3.7-litre engine developing 75 b.h.p., and ,mounted on 'rubber at three points. Like the . Max, it also has a five-speed gearbox giving an over-drive ratio, which can be engaged without thing the clutch.

Other goods models will be the well-known light 4-tonner, with, a drop-sided lorrY' body, and a 40-ewt. forward-control van for parcels service for the L.M.S. Railway Co, The passenger side of the business will be catered for by an Arrow Minor 25-seater coach with a sliding roof; a Lancet oiler affording a body length of 24 ft., and incorporating a four-cylindered oil engine and a five-speed gearbox, as in the Max chassis; a Lancet 32-seater coach with a Big 4" petrol engine; and a Lance 48-seater double-decker for the Aldershot and District Traction Co., Ltd. The Lance is also an oiler.

The company's extensive business in fire-fighting appliances will be represented by a " Light 6 "fire-engine having a six-cylindered overhead-valve engine of 90-100 b.h.p.; the pump has an output of 500-600 g.p.m., whilst a 40-gallon tank is provided for the separate first-aid pump. Another fire appliance will be a 350-500 g.p.m. trailer pump of the type supplied to the Home Office. This has a four-cylindered 66 b.h.p. petrol engine direct coupled to the pump, which is of the turbine type. Provision is made for carrying adequate lengths of suction and delivery hose.—Dennis Bros., Ltd., Guildford,

AGROUP of three new models is to be introduced by the Diamond-T conCessiOnnaire at Earls Court next month. It will comprise model 46, a 2i-tonner; model 60,

2-3-tonner, and model 66 RX, a rigid six-wheeler. Par

ticulars of the first and last of these three must be withheld until the curtain risei, but of the intermediate i-Aachine we

are able to give a brief description. .

WhilsfforloWing; iir the Main; previous layout, the vehicle has 4 smaller power unit than was forn-ierly installed in the earlier 'chassis of similar rating. Tri addition, the frame is straight,. and in the' suspension -systera "overhung rear springs are a point. Behind the cab there is 12 ft. of body space, but in spite of this the cab is not cramped. The power unit is rated at 27.34 h.p., 'and isa six-cylindered engine of 3.622 litres.. It hasside valves and a maximum output of 66 b.h.P. at 3,090 r.p.m.

Modern practice is revealed in the Tocco hardened crankshaft and the cadmium-alloy bearings. Mixture is supplied by a Zenith'carburetter, and' the electrical equipment is of Auto-Lite make. A Hardy-Spicer propeller shaftlooks after the transmission between gearbox and side, the ,latter being of markedly substantial construction. Braking is by the Lockheed system, and the rear springs have sliding ends in piece' of shackles.—Diamond-T Motors, 414, London Road, Isleworth, Middlesex.

OF the range of 11 Dodge vehicles to be shown, the new 26-seater Duple-bodied coach will undoubtedly command considerable attention. It has a six-cylindered petrol engine with a piston displacement of 3.569 litres, giving 73 b.h.p. at 3,000 r.p.m. A four-speed_ gearbox is installed, the drive to the rear axle being by an open twopiece propeller shaft provided with Hardy-Spicer needleroller-bearing joints. The transmission line is offset, and the rear axle is underslung in Conjunction with deeply arched frame side members. Known as model SBF, it has a wheelbase of 14 ft. 9 ins.

Considerable modifications and improvements are to he found in the 2, 3, 4 and 5-ton models; with a view to giving increased strength, greater efficiency, improved

appearance and better comfort in the cab. A point of outstanding interest lies in the braking system in which the new Lockheed slotted shoes are used Thicker and wider facings provide 25 per cent, greater frictional area.

Engine accessibility has been considerably increased, and a lower centre of gravity has been obtained, by mounting the engine and gearbox lower in the frame. This feature affords increased stability and greater road adhesion.

By employing a deeper radiator shell, which is now separate from the radiator block, lower cab and bonnet, .c3/3 and new type wings blending into the bumper, the frontal appearance has been considerably enhanced. A 15-cwt. an and a new /-ton delivery van will also be staged.

NRANUFACTURED in the ordinary iva.y of business, withVol out any special preparation for exhibition, six products of R." A. Dyson and Co., Ltd., be displayed on this stand. Special interest attaches to the patented road-rail tanker-trailers. • One will have a glass-lined tank lagged with Alfol to a depth of 4 ins., 'and incorporating a beating arrangement for keeping the contents hot during transit. Another road-rail tanker is for 2,000 gallons of milk, and has a body of Firth's Stainless steel, lagged with Alfa which is covered with aluminium sheets. The former is for edible oils and the hot-water system is electrically operated and electrically controlled.

The four-wheeled low-loading trailer should be worthy of special inspection, because the front axle' incorporates an ingenious swivelling steering.arrangenient, and The axles are suspended in a novel manner. If neceSsary, they can quickly be detached to .enable the chassis frame to be used ais•a bed for accommodating a load. Another trailer will he a light

weight 8-tosiner; • , On the semi-trailer side there Will be available for inspection a fixed attaehment coupled to a Leyland Cub tractive unit, and a detachable semi-trailer used behind an International tractor.—R. A. Dyson and Co., Ltd., 76-80, Grafton Street, Liverpool, 8.

VILINICIPAT., officers will be particularly interested in the LYE Eagle 15-24-cubic-yd. outfit, based upon a Thornycroft Sturdy low-loading chassis. The Compressmore refuse body is built of steel throughout and electrically welded.

A Thornycroft Trusty tractor will be seen coupled to an Eagle 12-ton semi-trailer, affording a body length of 23 ft. A 3-ton 3-cubic-yd. all-steel end-tippin., semi-trailer is to be attached to a Scammell 3-ton mechanical horse, the hydraulic tipping gear being hand operated:

Another exhibit of note will be a 6-ton patent movingfloor general-purpose trailer, with a fixed front board, sides hinged at the bottom and a tailboard hinged at the top. Apart from small components, such as tipping gear, the exhibit will be completed by a four-wheeled high-speed trailer.—Eagle Engineering Co., Ltd.-, Warwick.

GARDNER oil engines will be fitted to all the seven vehicles to be exhibited by E.R.F., Ltd. An imPressive eight-wheeled ,chassis, With a' six-cilindered oil engine. represents a -21st repeat order from the Marston Valley Brick Co., Ltd. • Another eight-whbeler of similar type will

be shown as a hinged-sided lorry, with a body 24 ft. long and a saloon cab incorporating an illuminated sign.

A tribute to the quality of E.R.F. vehicles is contained in the fact that the C.I.662-type six-wheeled hinged-sided lorry to be shown is to be delivered to Southurn Roadways, Ltd., to a 23rd repeat order. Double steering axlei are incorporated in.the C.I.561S model, which, Mounted on 40 by 8 tyres, will appear as a platform lorry. Three four-wheelers will be shown, two with four-cylindered engines and the other with a five-cylindered power unit.

HAVING an entirely redesigned chassis frame with boxsection side-members and tubular cross-bracing, the sturdy little Jowett will be seen in four examples, two 8 h.p. vans and a couple of lorries of 10-cwt. capacity.

A new style of body has been adopted, with box-type wheel-arches to increase loading space. The hill-width rear doors are equipped with check hinges, whilst the front door is particularly wide. The front and rear axles are of new design giving 4-ft. 0i-in, track. An attractive feature of the specification is the use of Bendix-Cowdrey self-servo brakes, operated entirely by pull rods in tension. The engine is of the twin-cylinder horizontally opposed watercooled type for so long associated with this make.—Jowett Cars, Ltd., Bradford Road, Idle, Bradford.

WHELST specializing in municipal vehicles mainly W adapted for specific purposes, the Harrier concern also manufactures machines of a type that fill many requirements of operators. Specimens of its range in both classes will be on display.

e42 The exhibit will include the popular Bantam model, and examples of the Cob-Junior and Senior. The first two chassis have as their power unit a new four-cylindered engine, features of which are a sturdier crankshaft, bigger bearing surfaces for both the main bearings and big ends, and dual valve springs. In addition, a thermostat has been included in the cooling system, whilst the dynamo now employed is of the ventilated type.

There will also be on view a CK3 :3-ton dual-purpose low-loading machine and a CK5-5-ton fiat-platform lorry. The latter is a relatively recent addition to the Harrier range, and is essentially for long-distance hauls. It has 16 ft. 6 ins, of body Space and an 80 h.h.p. engine.

Three trolleybuses are to be 'included in the display, an E6a. six-wheeled 60-seater, and E4

56-seat four-wheeler, and another E4 shown in chassis form. All three have Metropolitan-Vickers electrical equipment, differential electric and air-pressure braking systems. On the six-wheeled 60-seater the wheels are shod with 10.5 by 20 tyres, the wheelbase is 17 ft. a ins, and the chassis, with electrical gear, weighs 5 tons 7 cwt. The two four-wheelers have 10.5 by 20 front tyres and 9 by 22 tyres at the rear. Their wheelbase dimension is 16 ft. and chassis weight 3 tons 17 cwt.—Ka.rrier Motors, Ltd., Biscot Road, Luton.

TEN models will be sponsored by Latil Industrial Vehicles, Ltd., one of the most interesting being the petrolengined Loco-Traulier for road-rail operation. The wellknown Mark I Traulier with four-wheel drive and four-wheel steering, and the timber-haulage outfit with a heavy-duty three-speed winch will also be seen. Both these models have four-eylindered 53 b.h.p. petrol engines. Mark II and Mark III Trauliers, and a Mark IT timber-haulage tractor. the last-named having a gas producer, will help to make the display one of the most outstanding in the Show.

The Mark II Traulier has a Gardner 4LK oil engine, whilst in the Mark III Traulier the rear-wheel steering may be locked to provide steering effect only on the front wheels. Two trailers will also be shown, one being for timber haulage, and the other an eight-wheeler mounted on 10.50 by 13 tyres.—Latil Industrial Vehicles, Ltd., 11, AlbertEmbankment, London, S.E.11.. THREE new chassis and a new engine will figure among I a variety of exhibits on the Leyland stand. Two of these chassis are goods models, the Lynx and the Steer, whilst the third is a passenger chassis for single-deck bodywork and known as the Gnu. The other exhibits will comprise a Titan double-decker, a 70-seater trolleybus, an Octopus van and a fire-engine.

The new Lynx weighs under 2i tons unladen, and, as a 12-ft-wlieelbase model, is rated to carry a gross load of about 5 tons 8 cwt., whilst with a 14-ft. wheelbase it can carry 6 tons 84 cwt. gross. Semi-forward control is employed and an unusual braking sytem is incorporated. The Steer is a six-wheeler with two steering front axles,

The Gnu also has two steering axles and enables 40-44 passengers to be accommodated in facing-forward seats on a floor unobstructed by wheel-arches,, beneath which there is ample accommodation for luggage. The radiator is located transversely over the frame on the near side of the engine.

The Titan double-decker will have a Leyland 56-seater metal-framed body. The six-wheeled 70-seater trolleybus, the chassis of which has been built to the specification of London Transport, will also be shown with a Leyland body.

The new engine to be seen is a Mark III petrol unit, which has been developed after many years' experience with the T-type unit.—Leyland Motors, Ltd., Leyland, Lands.

TREE -models, the Marathon and Magna passenger chassis, and the Mogul for goods, are being produced for 1938 by the Maudslay Motor Co., Ltd. An example of each will be seen oti this steed.

The Marathon will have a 32-seater luxury coach body

by Arthur Mulliner, Ltd., Northampton, whilst the Magna will be shown with a 40-seater coach body by Samuel Holbrook, Ltd., Wolverhampton. The Mogul is a 7i-tonner and the example to be exhibited will have a Mulliner cab. Low unladen weight is a feature of the Marathon chassis, which has a four-cylindered 32.5 h.p. engine of 81.5 b.h.p. The wheelbase is 17 ft. 7i ins., affording a body length of 32 ft. 6b ins, within an overall length of 27 ft. 6 ins. An interesting feature of the frame is that it incorporates longitudinal members of girder section. The chassis is also offered as the basis; of a ,39-seater bus.—Maudslay Motor Co., Ltd., Parkside, Coventry TWOgleaming polished chassis and a 45 b.h.p. oil engine in show finish will be displayed here. One of the chassis will be for bus work, and will be seen with a six-cylindered oil engine developing 100 b.h.p. at a governed speed of 2,000 r.p.m. The Aphon gearbox incorporates an overdrive.

The other chassis (for a 2-ton pay-load) has an OM 138 four-cylindered oil engine developing 45 b.h.p, at a governed speed of 2.800 r.p.m. A feature of this power unit, which applies also to that embodied in the bus chassis, is the use of a new heat-regulated automatic starting device.—British Mercedes-Benz, Ltd., 111, Grosvenor Road, London, S.W.1.

SPECIALLY designed for commercial service, the Morris light van admirably meets the trader's requirements. Four 10-cwt. vans will be seen finished in various styles. along with a couple of 5-cwt. vans and a 10-cwt.' chassis.

The larger model has, by the use of semi-forward control. the exceptional loading capacity of 119 cubic ft., apart from an additional space of 9 cubic ft, beside the driver. The platform, which is 7 ft. 6 ins, long and nearly 5 ft. wide, is easily reached through a large rear door, whilst the short wheelbase affords excellent manoeuvrability.

The 5-cwt. van has 58 cubic ft. of body space, including the area available beside the driver. As in the case of the 10-cwt. model, hydraulic shock absorbers are fitted both at the front and rear, in combination , with semi-elliptic springs. Hydraulic brakes are standardized -and dipping headlamps conforming with the new regulations. The low loading line is a useful. feature.—Morrie Motors, Ltd., Cowley, Oxford,

A VEIL of mystery hangs over the 1938 Morris-Com

mercial programme, and although we have peered below it, we are bound to secrecy. This much, however, we may disclose. There will be a range of new goods vehicles of popular sizes at attractive prices.

These are in the front rank in respect of body capacity considered in relation to unladen weight and wheelbase length, whilst their general layout, and the sizes and design of the engines installed-will ensure efficient running and roadworthiness, together with ample power fnr performance. —Morris-Commercia.l Cars, Ltd., Adderley Park, Birmingham, 8.

REQUIREMENTS of several trades are met by the vehicles to be arrayed on the Oldsmobile stand. For instance, there will be a C112-type 1-tanner, with extensions and chains, suitable ffir a dairyman or mineral-water manufacturer, whilst another 1-tanner is for the laundry trade.

Builders' merchants and others will be interested in the two tippers, the 3-3t-toriner having B. and E. hydraulic end-tipping gear and weighing 2 tons 7/r cwt. unladen, and the 4-tonner having an Anthony all-steel body and vertical hoist. The latter machine weighs 2 tons 9i cwt. unlacieri. For the furniture remover there will be a 4-ton 1,000-cubic-ft. van weighing 2 tons Oi cwt. unladen, and tor the trunk-service operator a 5-6-ton lorry of approximately the same unladen weight. A 3-3i-ton lorry of standard design will complete the exhibit.—Oldsmobile Distributors, Ltd., 5, Lower Marsh, London, S.E.I.

VANS, lorries, a 26-seater bus and a shooting brake will comprise the Opel exhibits. The smallest model will be an 8-10-cwt. van costing 4150, with a 1.279-litre four-cyliedered engine. The shooting brake will also be based upon an 8-10-cwt. chassis.

c44 The 3-tonner, which has a six-cylindered overhead-valve engine of 3.636 litres, developing 79 b.h.p., will be shown as a drop-sided lorry and as a Luton van. The gearbox provides five forward speeds.—General Motors, -Ltd., 3, St. James's Square, London, S.W1.

L-LECTRIC vehicles for passengers and

goods will be featured by Ransomes. Sims and Jefferies. Ltd. On the passenger side there will be two trolleybus chassis, one being designed for a double-deck body and the other for 24-seater coachwork. In both cases, a motor of the chassis maker's owr design and manufacture is used.

The electric tracks will comprise an indus trial 2-tonner and an elevating 2-tonner. Each is equipped with four-wheel steering mechanism.—=Ransomes, Sims and Jefferies, Ltd., Orwell Works, Ipswich.

ALTOGETFIER 15 Reo vehicles will be seen at the Show, eight embracing the full range of 15-cwt., 3-ton, 4-ton and 5-ton units with long and short wheelbases, appearing on the maker's own stand. Particularly impressive will he

a 3-ton streamlined van with a body built to the special requirements of Collars, Ltd., by Manhire, Chandler and Co. The interior is fitted with shelves, and a sliding door on the near side makes for easy entrance and exit.

The 15-cwt. van to be shown is for dairy Service in Scotland. Mechanically minded visitors will have an opportunity of examining details of design in a 16-ft. wheelbase 3-ton stripped chassis. An unusual exhibit will he a mobile concrete mixer incorporating a 13-ft. 10-in, wheelbase chassis, in which a Gold Crown 73 b.h.p. engine is embodied. Another identical' chassis will be seen with a drop-sided lorry body, for use by a Cornish agricultural society.

The 5L 5-tonner, an extremely powerful vehicle weighing under 2i tons unladen, will be seen in stripped form. The display is to be completed by a somewhat similar chassis, but with a longer and heavier frame and carrying a special boxvan body.—Reo Motors, Ltd., Great West Road, Brentford, Middlesex.

NOVELTY gives the Renault Estate car precedence among this company's exhibits. It is a general-purpose machine, providing seating for seven without cramping, or a clear goods-carrying space for 10 cwt., the conversion

being a matter of but a few seconds. The windows standardized afford complete weather protection when lowered, but when not required can be slid upwards into the roof.

There will also be a 10-cwt. and a 15-cwt. van, both powered by four-cylindered engines. These are mounted on rubber, whilst, to insulate road vibration also, special attention has been paid to the suspension, a transverse rear spring being a feature. Ash-framed, pressed-steel bodies are employed; their constructional strength being a noteworthy point. In reference to the controls, it should be mentioned that a horizontal pull-type lever operates the hand brake, thus eliminating an obstruction in the cab.—Renault, Ltd., Western Avenbe, London, W.3. enumerate the items in the fine exhibit of this com pany, there will be a 15-16-ton rigid eight-wheeler, an articulated eight-wheeled tanker, a gun tractor chassis, n 6-10-ton articulated five-wheeler, a 3-ton mechanical horse motive unit, a low-level 3-ton trailer, a 1,200-gallon mechanical-horse street washer, another 6-ton five-wheeled articulated outfit and a battery electric 4-ton mechanical horse and semi-trailer outfit. Of these, the first and last are specially interesting, by reason of their novelty.

The electric machine has a motor of 9.5 h.p., which is asbestos-insulated and ventilated. The controller provides four speeds and is operated by foot. There is a charging socket and cut-out switch and there are two Exide batteries, which weigh I5j. cwt. A feature of the transmission is the double-reduction final* drive. This vehicle resembles, in many respects, the well-known petrol M.H. model.

Turning now to the eight-wheeler, outstanding points inblude rubber forward suspension, the four wheels of the front bogie being mounted on' a subframe, this assembly supporting the • forward part of the chassis through the medium of rubber columns. Its construction is highly ingenious and will well .repay close inspection. The model shown has twin rear tyres and steel7spring rear suspension. Where single tyres are used, rubber suspension is standardized, similar to that shown on the big articulated tanker

mentioned above. Both systems are standard types. Other notable points include the double-reduction epicycfic rear • axle and the constant-mesh sliding-dog six-speed gearbox. —Scammefl Lorries, Ltd., Watford.

RIGID extensions converting a Bedford 3-tonner to a 6-ton six-wheeler and a Dodge 5-tonner to an 8-ton sixwheeler will be shown. The former must represent one of the biggest-capacity vehicles in the 30-m.p.h. class available, for the complete machine has an unladen weight of

under 50 cwt. Despite the use of six wheels and such equipment as' vacuum-servo brakes, the weight has been kept down without any suggestion of sacrifice of strength. The axles and balance beams, hub bearings and so forth, are all of ample dimensions. Moreover, a pleasing cab streamlined design, with hardwood frame and aluminium panelling, is employed, and its equipment is of high quality. A loading space of 12-ft. 6 ins, is available.

• On.the 8-tonner the foot brake operates On all six wheels through a standard Lockheed system, and two independent .servo, units work on the trailing wheels. The body has a Capacity of 6 cubic yds. and the end-tipping gear provided is of the Anthony cam type. The wheels are shod with 34.b 7 heavy-duty tyres.—G. Scainme11 and Nephew, Ltd.. Fashion Street, London, E.1.

ANCILLARY users of delivery vans can be almost certain that, in the range made by the Singer company, they will find a vehicle expressly adapted for tt eir particular requirements. Examples will be shown at Earls Court of vehicles suitable for specific trades. Briefly to outline a typical Singer 5-7-cwt. model, it has a 9 h.p. fourcylindered engine, affording the rapid acceleration required for quick-delivery work. An effective floqr space of -19 sq. ft. is afforded. Al the back there ar detachable doors—a feature of unquestionable practical ad antage. A point by no means usual to-day is the p ovision, as standard, of a fixed starting handle. It encou4ages swing

ing for the initial start, thus relieving the bat of heavy strain. Steps are taken to keep exhaust fumes from entering the van, and adequate means for ventilatcfii are provided.—Singer Motors, Ltd., Coventry.

GOODS vehicles, ranging from 3-5 tons in capacity, will comprise this exhibit. The smallest is the Studebaker Leopard, which will be on view in the form of a steel-lined hydraulic tipper. It has a six-cylindered engine, developing 85 b.h.p., a feature being the use of electro-plated castiron pistons. With a similar body is the 4-tonne-I-, powered by a Hercules engine of 4.31-litres capacity. In this case, a rear axle, incorporating a double-reduction gear is employed.

Two Puma 5-tonners complete the exhibit. One will be shown as a forward-control chassis and the other as a dropsided lorry. These also have Hercules engines, but of higher power than in the case of the 4-tonner the piston displacement being 5.244 litres. Another intersting point

is that they have five-speed gearboxes. Moreover,the tbraking system includes power servo with Loc heed trans

mission. The standard tyre sizes-axe 34 by 7 at• the front and 96 by 8, twin equipment, at the rear. With 8-ft. 5-in. wheelbase, the chassis weight of the Puma is 45 cwt.— Studebaker Distributors, Ltd., 385, Euston Road, London, N.W.I.

rrROLLEYBUSES and battery electrics will feature in 1 this " all-electric exhibit," to quote the Sunbeam company's words. There-are to be four trolleybutes on viewand two examples of the new 12-15-cut. goods vehicles. one shown in chassis form so that the general layout and B.T.H. equipment may be examined, and the other as a complete vehicle with a body by Glover, Webb and Liversidge, Ltd., built to the order of Selfriage and Co.., Ltd.

The trolleybus exhibit will,comprise a six-wheeled chassis of the long-wheelbase type, a similar machine carrying a 60-seater body, built for Walsall Corporation, and two fourwheelers (both double-deckers), one with a 54-seater body for Wolverhampton Corporation, and the other with a 60-seater Metropolitan-Cammell-Wernann body for the City of Johannesburg.—Sunbeam Commercial Vehicles, Ltd., Moorfield Works, Wolverhampton.

ASPECIALIST in low-loading ambulances, the Talbot company will exhibit two examples. Six-cylindered engines power both. One is of 20.9 h.p. and the other 17.9 h.p. The latter transmits through a synchromesh gearbox and the former through a preselective self-changing unit. A particularly interesting feature of the former chassis, however, is that the rear axle incorporates, in addition to spiral-bevel final drive, a double-helical gear reduLtion to each wheel. By means of this. transmission system, an exceptionally low floor level is possible. Another note worthy point is the standardization of Luvax driver-control shock absorbers. Built specially for Middlesbrough Corporation, the 20.9 h.p. ambulance has an overall height of only 6 ft. 10 ins, for negotiating low bridges.

Unlike the larger machine, which has provision for mounting the stretchers one above the other, the smaller ambulance has the stretchers arranged on each side. In

addition, the Talbot easy-loading ramp is provided, and a point that should not be missed is that, besides devoting every care to the comfort of the patient. that of the driver has not been neglected.—Clement Talbot, Ltd., Barlby Road, Ladhroke Grove, London, W.10.

NAOST interest will attach here to two of the seven 1.11.exhibits available for inspection. Of these, we will refer first to the 14-15-ton low-loading trailer constructed expressly for carrying heavy machinery, yet legally permitted a speed of 20 m.pele It has tandem axles, the wheels being shod with 29 by 8 tyres. Each hub has its awn Dewandre vacuum-servo cylinder for applying an ' 18-in. brake. The floor height is only 3 ft. 1 in.

Next, there is the 10-12-ton quickly detachable semitrailer, having twin oscillating axles; this is one of the biggest of its type on the market. Bendix, brakes are used id this case, all four hubs being so equipped and the drum diameters being 16 ins. A Dewandre servo motor is provided for each pair of brakes. At the front there are heavyduty screw-down jockey wheels, and the body is 20 ft. long.

In addition to these, much of interest will be found in the all-steel timber carriage; the four-wheeled trailer carrying a 1,050-cubic-ft. pantechnicon body; a quickly detachable 8-ton semi-trailer, shown attached to a Thornycroft tractive unit; another 8-tormer of the swan-neck type: and a 5-6-ton four-wheeler equipped with a platform body. —Taskers of Andover (1932), Ltd., Waterloo Iron Works, Andover.

NAMED the Beauty-ride, the outstanding exhibit of the Thornycroft company will be an entirely new 26-seater. The chassis is suitable for both buses and coaches, and has been designed to provide seating capacity for 26, with adequate accommiedation and comfort for the passengers.

Whilst based on the design of the well-known Sturdy model, there are many definitely new features. As examples, we may quote the cranked frame and underslung, fully floating rear axle, the use of 7.50 by 20 low-pressure tyres, and the treatment of the dash and front wings, an object of which is to afford a modern and pleasing appearance.

There will also be exhibited a new type of four-cylindered petrol engine, designated the TC4.

In addition, there will be on view representaves of the Sturdy class, namely, a 5-tonner in the 30 -m.p.h. class; normal and forward-contro: types, notably a 13-ft. 4-in. forward-control chassis; a fixed-sided lorry; a 4-cubic-yd. tipper ; a box van built for the special requirements of the Gas Light and Coke Co., and 4 and 5-ton lorries. Representing the Truse3r series, there is an oil-engined machine in the maximum-load four-wheeled class. A point to observe is the generous use of Elektron in the construction of the power unit. The vehicle has a 21-ft. 10t-in. body. Of interest to overseas visitcrs will be an Amazon three-axle 20-seater chassis, designed for travelling on rough tracks ; it is one of a large order for the Iraqi railways. The rear suspension permits a wheel articulation of 9 ins.— John I. Thoniycroft and Co., Ltd., Thornyeroft House, Smith Square, London, S.W.1.

I NDEED of advanced design, certain of the machines

to be shown here will, without doubt, rank as highlights of the 1937 Show. In all, the exhibit will comprise seven vehicles. The two Successors and the Yeoman are of absolutely new design and have eight-cylindered oil engines of the horizontally opposed type. The engine is mounted behind the front axle between the frame side. Imembers, and, behind it, a Maybach seven-speed vacuum-operated preselective gearbox, whilst, in the case of the Successors, the four rear wheels are independently suspended, the system incorporating bell cranks and coil springs. There is a wealth of interest to be found in an examination of these three outstanding vehicles. The Successors are for passenger work and have six wheels, whilst the Yeoman is an 8-ton four-wheeler.

This company is aisle introducing two battery electrics, one a 2-3-ton four-wheeler and the other an electric horse with three wheels, designed for use with asemi-trailer and of the same capacity As the four-wheeler:

In addition, there will be an example of the well-known Express 32-seater,, poviered by a four-cylindered petrol engine of 75 b.h.p., and a military petrol-electric lorry. On the last-named there is a dynamo coupled to the engine by a short shaft, whilst a motor drives the rear axle, via a propeller shaft and Cotal two-speed gearbox electrically operated from a dash switchbox. The exhibit has W.1),type cab and lorry body and full military equipment for searchlight operation.—Tilling-Stevens. Ltd., Maidstone.

DOWERED by two-stroke engines, three Trojan models I will he shown, the exhibit comprising an Express 7-cwt. van, a Senior 12-cwt. van, and a Special Senior vehicle of similar capacity. The last-named has a capacity of 160 cubic ft. and weighs 181 cwt. ; it is low in first cost and economical to run. This, indeed, applies to the whole Trojan range. As an instance may be quoted the claim of the maker that the engine never needs decarbonizing, so that the delays occasioned by holding up a machine for this work are avoided. Other maintenance operations are reduced to the hare minimum by the simple construction used throughout. In the engine there are only seven separately moving parts, whilst the epicyclic two-speed gear is " foolproof," of simple construction, efficient and requiring the minimum of attention.

For the benefit of those who are not acquainted with the design of the unit, the system is to employ two pairs of cylinders arranged close together and side by side. For each pair there is a common combustion chamber, an arrangement which gives excellent scavenging, smooth and economical running and eliminates troubles which have been c4R'

experienced with other designs of two-stroke. As proof of the claims made by this manufacturer is quoted the fact that in this country one operator uses no less than 1.000 Trojan vans.—Trojan, Ltd., Purley Way, Croydon.

EIXAMPLES of the T.T.A. Four:in-Line detachable semitrailer....trailer and the company's Rock hydraulic end-tipping gear will be displayed. The former will be attached to a Moths-Commercial tractive unit. Its main feature lies in the rear-axle arrangement; the four wheels, as the name implies, are arranged in line across the chassis, each pair being mounted on the ends of a rocking axle. A system of twin springing is employed and the coupling

gear is of the latest automatic type. On this chassis will be mounted a van body, panelled in polished aluminium, Advantages of the wheel and suspension arrangements include freedom of each wheel to follow road surface contours and to rotate at the appropriate speed when cornering. These are reflected in decreased tvre wear.

A Reo 3S chassis forms the basis of the machine on which the tipping gear will be displayed, the body being steellined ; the whole scales under 50 cwt.—Truck and Tractor Appliance Co. (Manchester), Ltd., Richmond Road. Trafford Park, Manchester.

hAUCH interest is sure to he aroused by an entirely new IVI lour-wheel-drive tractor, which is being introduced at the Show by the Unipower company. It has a six-cylinciered engine of 85 b.h.p. and transmits to the axles via a five-speed primary gearbox and a two-speed auXiliary gearbox. Use is made of both Hardy Spicer and Rzeppa universal joints, the latter featuring particularly in connection with the drive to the front wheels, by which, of course, the machine is steered. Also there will be on view the company's latest two-axle-drive bogie unit, which has a

capacity of 8-10 tons. Basically, the design resembles former Unipower bogies, but in many details improvements have been effected. For example, the wheels are now equipped .with -Girling 16-in, by 44-in, brakes, the axles are of increased capacity and modifications have been made to the auxiliary gearbox, with a view to affording it additional strength. A feature is the system employed for adequately lubricating the spring-end trunnions —Universal Power Drives, Ltd., Aintree Road, Perrivale, Middlesex.

NJARIOUS examples of the Vulcan company's products V will feature on this stand. Among the 5-tanners will be a forward-control chassis, the same model with a lorry body mounted upon it, and yet another carrying a ripping body.

In the case of the first two., Vulcan four-cylindered engines are used, the bore and stroke .being 10/ mm. and 140 mm. whilst the third is powered by a Gardner 4LK unit of 3.8litres capacity.

There will also be a cattle lorry of the forward-control type and designed for low-loading. . The bodywork here is a Jennings product, described as of the three-purpose type. It has a permanent flat platform and a removable container. Without the last-named, the machine weighs under 24 tons. In this case, the power unit is of 60 b.h.p., having four 90 mm. by 120 mm. cylinders.

A normal-control lorry of 35 cwt. will be shown with detachable drop sides and a 10-ft. platform. On this, the Vulcan 85 mm. by 130 mm. four-cylinder engine is installed. The exhibit will be completed by a 24-ton .forward-control Luton van, of approximately 800 cubic ft. capacity and weighing complete under 24 tons.—Vulcan 'Motor and Engineering Co., Ltd., Crossens, Southport.
