1924: THE INTENTIONS OF THE TRADE

A Brief Résumé of the Plans of the Makers of Commercial Motor Vehicles and Municipal and Contractors' Appliances, for the Coming Year.

SEEMINGLY, at the moment of going to press, every maker has not yet decided upon the full scope of his catalogue, much of which must, of course, depend upon the extent of the manufacturing programme decided upon. We say this because we are not in a position to deal with the intentions of a few concernig, and information concerning them must be deferred until the second or third Show Number.

With this proviso, in the following pages will be found set out, in the briefest manner possible, a résumé of the intentions of each concern in the trade as separate and distinct from a forecast of the exhibits at the forthcoming Shows, which will be covered in the second Show Number to be published next week.

It will be found, on a perusal of these pages, that the commercial motor vehicle industry is alive in every Sense of the term. There is no absence of energy or enterprise, nor shortage of ideas, Every phase of trnsport and every need of the constructional contractor and of the municipal official that . can be covered by motive power is given the fullest consideration, and. vehicles and appliances are developed that will comply with requirements and will operate efficiently and effectively.

A.E.C.'s Goods and Pwsenger Models.

MHE schedule of A.E.C. commercial vehicle and motor coach chassis for 1924 is now more varied than ever, with the addition on the one hand of the, new 2-ton chassis -and on the other of the six-wheeled tractor-trailer combination. It is only possible in a brief review, as the one upon which we are now engaged, to give some of the leading particulars of a few of these chassis.

Considerable interest will, we think, attach to the sixwheeler. We understand that the company, in designing this vehicle, took the line that it should be designed as a whole, and not made up of a four-wheeled vehicle. of short wheelbase coupled to. an independently designed trailer. The design and construction of the front and rear portions of the A.E.C. six-wheeler have therefore been 'regarded as one job and should. give. service -accordingly. It .is intended that it should be capable of carrying 8 tons of useful load at 12 miles an hour or 10 tons at-8.miles an hour, but there is, of course, a considerable margin over and above these capacities.

The 2-ton chassis has recently been described in these columns. Its outstanding -features are the design and its engine, in which the whole of the tappets and valves are enclosed in the crankcase, so as to be thoroughly lubricated.

The ignition of this power unit is by Delco coil. The handbrake arrangement is interesting, being mounted on the side of the gearbox and operating the internal-expanding brake shoes immediately behind the box through the medium of bevel gears, the whole of tile brake-operating mechanism being actually contained in the gearbox casing. The final drive is by worm and ..vheel.

This company's schedule of chassis includes goods vehicles, having capacities of 2 ten, 3-4 tons, 4-5 tons, as well as the 8-10-ton tractor-trailer combination referred to above. The principal lines in passenger vehicles include a 20-seat coach on the new 2-ton chassis, and buses of all descriptions.

At Olympia will be exhibited two models of the 2-tonner, one a chassis and the other as a saloon bus ; one model of the tractor-trailer combination, tractor portion only ; a thousandgallon oil tank on .a 3-4-ton chassis, and one of die latest N.S.-type double-deck buses, with capacity for 54 passengers.

Albion Introduce "Mark H" Engine.

BESIDES the introduction of -tbe new model which was described recently in these columns, the Albion Motor Car Co., Ltd.-, have-made several modifications to the other chassis on their programme, -which for 1924 includes a 25-cwt., a standard 30-cwt., and also the W.D. subsidy 30-cwt., a 2, 21, 3 and 4-ton, a. special 72-cwt. fantechnicon chassis, and tipping wagons on 30-cwt., 2-ton and 4-ten chassis.

In connection with the tipping wagons, the two smaller models may be had either with hand-operated gear or hydraulic. They may be either end-tipping or three-way tipping. On the 4-tonner, however, only hydraulically operated bodies are supplied. Two Albion ambulance chassis are included in the schedule, one of 20 h.p. and the other of 24 len. The chars-a-bancs include a. 15-seater, 19-seater aiad 20-23-seater, and there are buses for 12, 16 and 18 passengers.

Amongst the minor modifications which have been effected on Albion products, the 32 lip. engine has been revised, and for the future those 3-4-ton chassis to which this new engine is to be fitted will be known as Mark II. There is no change as regards the frame and transmission, but the bonnets and radiator have been given more shapely outlines. The Albion Motor Par Co., Ltd., Scetstotin, Glasgow.

Five Allehin Models of Steam Wagons.

ALLCHIN steam wagons are made in five sizes, for net loads of 3, 4, 5, 6 and 12 to 14 tons, the last-named being a six-wheeler tractor-trailer combination. The same general specification, applies to all the models, the popular overtype construct-ion being the basis. Each is fitted with a compound steam engine, spur gear transmission and final drive by miller chain. The 3, 4 and 5-ton models have two speeds, the 6-ton and the 6-wheeler three speeds. The braking equipment of all these wagons embodies a foot brake,, acting on drums an the rear wheels, both of which are detachable, and a hand brake, which takes effect on a steel drum on the rear axle.

A feature of all Allchin models is the patent coupling, which eliminates much of the risk which ordinarily attaches to the process of connecting "a trailer to the wagon. In the ease of the Afichin the coupling is automatically effected when -pressure is applied to this device by the drawbar as -the tractor approaches the trailer.

Arnittrong-Whitworth Series of Road Rollers.

SIR W. Or. ARMSTRONG-WHITWORTH AND CO., LTD., are developing their roadmaking machinery department pretty considerably, and have recently added a new road roller to their programme, which is described as the Quick Reverse Light Road Roller, and is specially designed for asphalt and bituminous carpeting. The rollers are arranged in tandem, with short wheelbase, and are equally loaded. The firm's complete programme embodies this new machine, as well as the 8, 10 and 12-ton rollers, one of which was shown at the Royal Agricultural Show this year, and also a comprehensive range of mixing and drying plant for various classes of roadmaking material. The new tandem roller and various examples of this roadmaking machinery will be exhibited at the Public Works, Road and Transport Exhibition at the Agricultural Hall. Sir W. G. Arnistrong-leVhitworth and Co., Ltd., Elswick Works, New castle-on-Tyn e.

"Austin Seven" as a Traveller's Car.

MHE schedule of commercial motor Vehicles manufactured

by the Austin Motor Co., Ltd., embraces three different types of chassis. There is the 7 -h.p., which has been found to be admirably suited for use as a commercial traveller's car, in which guise it is equipped with space at the back for the carriage of samples. This chassis is quite a remarkable little production, having many interesting and almost unique features; its engine is a neat little monalloct of four cylinders, 56 mm. and 76 mm. bore and stroke. Engine, clutch and gearbox are unit mounted, the clutch being a single dry disc and the gearbox providing three speeds forward and reverse. The chtngespeed and hand-brake levers are centrally located, the final drive is by spiral bevel, and the brakes take effect on all four wheels, all parts of these brakes being interchangeable. Next in line comes the 12 h.p. chassis, which is very similar to that of the well-known Austin touring car of the same power and embodies a four-cylinder monobloe engine of 72 mm. and 102 mm. bore and stroke. The clutch is of the single dry disc type and the gearbox provides four speeds and reverse, with centrally located change-speed lever. Final drive is by spiral bevel gears to a rear axle of the semifloating type. The design of the 20 h.p. Austin, which is suitable for use either as a, van or ambulance chassis, follows closely that of the 12 h.p. just described, except as to its dimensions. Its engine has a bore and stroke of 95 mm. and 127 mm. and its tyre equipment is 820 mm. by 120 mm. cords. The general specification follows almost. exactly that of the 12 h.p. The Twenty will be exhibited at Olympia as an ambulance and as a light van. The Twelve also appears as a van, while the Seven is hOwn as a traveller's car, asai, 2i-cwt. vary, and as a single passenger taxi. The Austin Motor Co., Ltd., Longbridge, near Birmingham.

Barford and Perkins Road Rollers.

MHOSE products of Barford and Perkins, Ltd., -which are of direct interest, to readers of this paper, include the company's several types of internal-combustion engine road rollers and the accessories and equipment for these machines. Selected examples of these rollers will be exhibited at the Public Works, Road and Transport Exhibition at the Agricultural Hall. There will be a three-wheeled water-ballast motor road roller, equipped with scarifier. This machine has a. 30 h.p. to 35 h.p. four-cylinder engine which consumes paraffin. Its nominal weigbtf empty is 12 tons, which can be increased by means of the water ballast to 14i tons. Another exhibit will be a tandem roller of 8-9i tons. This is a 20 h.p, four-cylinder engine and also consumes paraffin.

Another exiiIhit is a road roller specially designed maintenance of • footpaths—the three-wheeled machine 36 cwt. and equipped with a 10 h.p. engine.

Atkinson Incorporates a 2-speed Gear.

THE .chief item in the 1924 programme of Atkinson and Co., Frenchwood Works, Preston, will undoubtedly be their latest type of. steam wagon, which embodies-a change-. speed gear so as the better to fit it for operation in hilly country. The embodiment of a gearbox in a steam wagon of the und.ertAe, if not altogether an innovation, is at least sufficiently out of the ordinary to justify comment. It may be remembered that this -wagon was fully described a few weeks ago in this journal. Formerly it has been the custom of the makers of • this wa.gou to vary the final drive ratio in accordance with the area into which the wagon was being sold and in which it would presumably, therefore, be most..corrunonly used. On this new Atkinson an epieyelic gear is mounted on the engine crankshaft, which gives a low gear 2.8 times that of the normal or high gear. The wagon may now, therefore, be designed for easy conditions, the driver making Use of this speed gear when he desires to negotiate a hill. Besides this model the Atkinson programme includes a full range of steam wagons for loads of from 2i tons to 8 tons inclusive. Their products are too well known to need more than the briefest mention ; it need rally be stated that they embody vertical water-tube boilers, undertype engines and final transmission by chain. A feature of the engine is its arrangement of steam distribution. Each cylinder is equipped with steam valves only, the exhaust making its way out through ports in the cylinder walls, which are uncovered by the piston at the end of its stroke. Other points of interest are the Ackerman-type steering gear, the method of firing the boiler through a chide at the foot of the driver.

• Beardmore's Add a Van to Their Range.

BEARDMORE MOTORS, LTD., are now making a 25-cwt. lorry, as well as a taxicab. Examples of both still be shown at Olympia. The former is, of course, a novelty for this firm. The chassis was shown tentatively at the Glasgow Show at the beginning of this year, but since then it has been rigorously tested, and, as it appears at Olympia, embodies many modifications and improvements which those tests discovered to be necessary. It is equipped with the same engine and gearbeex as the taxicab, the former having four cylinders, with a bore and stroke of 31 ins. and 41 ins. respectively. The clutch is a Ferodo fabric-lined cone, and the gearbox affords four speeds forward and a reverse. The rear axle is of the full floating type, with D.S. worm drive. The brakes take effect, one on a drum on the cardan shaft, the others on drums in the Tear wheels. The tyre equipment is pneumatic, and the chassis adapted for gross loads of 30 cwt., including the body, or to accommodate light motor coaches with •seating capacity for 14 passengers.

Beardmore Motors', Ltd., 112, Great Portland Street, London, W.1.

Bernet Employ Four-wheel Brakes.

THE Berliet ptogramme of commercial motor vehicle chassis includes a 15-ce t. chassis, a 30-cwt., a 2i-tonner and a 6-tonner. Of these the largest is a worm-driven chassis, the others having final drive by bevel gear. The 21-tonner is particularly well adapted for use as a motor coach chassis, and for that purpose is equipped with four-wheel brakes. The engine ancLgearbox of this model are mounted as one unit, the gearbox having central control, the brake lever being at the right-hand side. The engine is a neat mcmobloc, with overhead valves, and the valve gear is of an ingenious design. _ At Olympia a model of each chassis will be shown, as well as a saloon omnibus and a single-deck omnibus on the 30-cwt. chassis, and an ambulance and a box delivery van on the 15-cwt. chassis.

Blackstone Locomotives and Agrimotors.

THOSE Blackstone productione of direct interest to commercial readers are the agricultural tractor and the paraffin-engined locomotive. In both of these machines it is the engine which affords the interest, as it is almost unique. It starts from cold on paraffin alone, the fuel being sprayed into the combustion chamber at the end of the compression stroke. Some of it is directed towards an electric-spark gap, where it is ignited. Compressed air for spraying is supplied by a. compressor driven by the engine, and a reservoir or container charged by this compressor enables the engine to be started from cold by merely operating the hand lever as in the case of a steam engine. A three-cylinder engine of this type is embodied in the tractor, which. is of the sell-laying track type, and also in the locomotive. The manufacturers are Blackstone and Ltd., Stamford, who will be showing at the Agricultural Co..all, a.rd not

at Olympia'2

Bonallack Market the GOtfredson.

BONALLACK and Sons have secured the sole concession in Europe for the Gotfredson chassis. The 30-cwt. chassis has a four-cylinder engine, with a bore and stroke of 3?, ins. and 51 ins, respectively, a single-plate fabric-lined clutch transmits to a. three-speed gearbox and thence the drive is by propeller shaft to an overhead worm and wheel. The brakes are what is known as Timken Duplex, i.e., embody four shoes in each drum—two for the hand brake and two for the foot brake—all in line. This chassis, although described as a 30-cwt., is made in two capacities, each with standard and long wheelbase. One is capable of carrying a net load of 25 cwt., and has a wheelbase of 10 ft. 11 ins, standard or 12 ft. "bag." The 30-cwt. Is of the same dimensions, but sightly altered in strength and gear ratios, so as to fit it for the increased load. The 40-cwt. chassis has an engine of 4 ins, bore and. 54r ins.

stroke; transmission is through a multiple-disc elutch to a four-speed gearbox. In other respects it follows the general. specification set out above for the smaller model.

Clayton Wagons Offer Three Types-of Vehicle.

THE output of Clayton Wagons, Ltd., for 1924 will be mainly along three lines the electric chassis being one of. them and the alternative types of steam wagons the other. As to the first, Clayton electric road vehicles are made in two main sizes, the first having a capacity ranging from 2 tons to 3& tons and the second from 4 tons to 6 tons. The general specification of the chassis embodies a single motor unit, mounted in a supporting casting which embodies the bearings of the countershaft. The final drive is by two roller chains to the rear wheels. —Both the under and over-type steam wagons are made by this firm, in capacities ranging from 4 tons to 12 tons in:elusive. The under-type embodies, as a special feature of Clayton construction, steam distribution valves of the piston slide type, operated. in conjunction with a very interesting and ingenious control gear. The over-type Clayton wagon, which will be exhibited at the Show, will have the traction-engine type of steering, although the makers also produce over-type chassis with Ackerman-type steering also. It is. to be en end-tipper, the tipping gear being operated by a small rotary steam engine, which drives the tipping screws through suitable gearing. Clayton Wagons, Ltd., Stamp End Works, Lincoln.

Crossley Market Two Commercial Chassis.

THE new Crossley subsidy chassis will, of course, be the main feature of the 1924 programme of Crossley Motors, Ltd,. in addition. to the-.old 25-30 h.p. The former chassis has a 30 h.p. engine with four cylinders, 4 5-16 ins, bore and 51 ins, stroke; it transmits through a cone clutch to a four-speed-and-reverse gearbox, and the final drive is by bevel gear. The standard equipment in.

eludes pneumatic tyres—singles on the front and twins On '

the rear.

The 25-30 h.p. chassis has 'a four-ea-Endei. engine of 4 ins. bore encl..% ins. stroke ; it also has the four-speed gearbox.

At the Show the 25-30 h.p. model Will appear as art-ambulance; the subsidy model will be shown as a chassis and as a complete tender.

Further Uses for the Daimler 2-3-ton Chassis.

TBE variation of the Daimler programme will mainly take the form of modifications in the length and equipmentof their 2-3-ton standard commercial motor chassis in order to lit it for numerous duties in connection with either load or passenger conveyance. This programme is exemplified to a considerable extent by the Exhibition models which are• being prepared. They include a char-à-barns, a double-deck omnibus, and a tipping wagon, all mounted on the same model chassis, which is modified in each case so as to make it more efficiently sera viceable•in eonnection with the particular duty.

For example, this chassis, which has a four-cylinder engine of 95 mm. bare and 140 mm. stroke, a four-speed gearbox and final drive by overhead worm and wheel, is equipped, for char-g-bancs purposes, with pneumatic tyres of 955 mm. by 155 mm. section—singles on the front, twins on the rear.

• It has a power-driven inflation pump, and is equipped with C.A.V. lighting. On the other hand, as an omnibus, it has Dunlop pneumatic tyres at the front, 36 ins. by 8 ins., but solid tyres of special section by the same maker at the rear ; while the tipping wagon is equipped with solid band tyres of 100 mm. sections for rims of 771 rem. diameter.

Durham-Churchill Make No Changes.

T-II.TRHANI, CHURCHILL, and Co. are making no altera

tion to their standard 3-4-ton chassis, which still remains as when we last described it. It is the sole model pic,duced by this company, and embodies a four-cylinder engine, 5 ins, bore and 6 ins. stroke and four-speed gearbox, with final drive by chain. It is suitable either for loads of 3-3,-k tons or for 28-30-seater motor coach work.

Dyson's All Steel Trailers and Attachments.

TTIFIE Dyson programme' of trailer production is, as is well

known, fairly comprehensive, and it ms,y, be said, therefore, that these exhibits at. Olympia really exemplify selections rathet than the whole range. Those exhibits will include a Dyson fifth-wheel all-steel trailer attachment, to carry loads Of 10 tons. There will also be an all-steel 4-ton trailer, this being of the Dyson special design with steel angle frame, arranged to carry a container, also of steel, 13 ft. 5 ins, long and 6 ft. 41ins. wide. This trailer is equipped with cast-steel wheels runnisrg on ball bearings, and is shod with solid rubber band tyre. The fore-carriage is so equipped that in case of ,need horse draught can be used as an alternative

,A 3-ton trailer will also be shown at Olympia. R.. A. Dyson and .Co., Ltd., 76-80, Grafton Street, Liverpool.

De Dion-Boutori to Make Eight Models.

THE De Dion-Bouton programme of commercial inoOr chassis embodies -in all eight models, out of which six are de-signed for goods-carrying purposes and the other two for motor coach work.

Concerning ourselves with standard equipment, these eight may conveniently be divided into two classes—those which are designed to operate shod with pneumatic tyres and those Nvilich are intended to be equipped with solid band tyres. . Those on pneumatic tyrea are for loads of from 10 cwt. to 40 cwt. inclusive, and their general specification embodies four-cylinder engines, with side-by-side valves, therino-siphon • cooling, with ignition lay h.-t. magneto, multi-disc clutches, four-speed gearboXes, and final drive by bevel pinion and • crown wheel.. Of the other four, the two which are designed for goods transport have capacities of 4 tons and 5 tons respectively.. Their general specification follows that already outlined, there being, of course, essential differences in the dimensions of the various models, in order to provide for the conveyance of the differing loads. The two passenger vehicles are for 20-seat and 32-seat motor coaches respectively.. The smaller oaf appears,to be in a class by itself as regards De Dien commercial vehicle design, since it has an ,overhead-valve engine with water-pump cooling. Its transmission, however,-follows the lines usual with this company, while the 32-passenger machine has an ordinary side-byside-valve engine with thermo-siphon cooling.

At Olympia there will be quite a: representative range of these machines on view, provision having been made'to show no fewer than four, namely, the 20-30-cwt. chassis, 30-40-ewt,, the 4-tonner, and the 20-passenger coach. De Dion-Bouton, Ltd., Woodside Works, North Finchley, London, N.12.

Eagle Introduce a Fordson Trailer.

-MHE EAGLE ENGINEERING CO.'S programme is del_ signed to enable them to meet. any possible demand for a tipping body to fib any chassis, or for a tipping trailer.

Amongst, the former category we must, make special reference to such unusual designs as that exemplified by the Warwick patent cesspit emptier. This is suitable for-use in connection with 4-4-ton chassis, and has a capacity of 750 gallons.

The trailer programme contains as its chief item of interest the two-wheel trailer, which is adaptable for use with a Fordson or any similar type of agricultural tractor. It can be obtained designed for leads of from-4-5 tons, and is equipped with hand operating tipping gear. One of its particularly

good points is that the brake operating 'handle is at the front of the tractor body, so that the brake can be controlled by the driver, without the necessity for him to move. In certain of its forms this trailer has a castor wheel, and may be drawn by horses, provision being made for that purpose in the form of shafts fitted to the rear of the trailer.

Then there is the Eagle-Ackerman all-steel chass,is trailer, made in various sizes for loads of from 2-6 tons inclusive, equipped with internal-expanding' brakes on the rear wheels, and solid-hand tyres.

The Eagle turntable trailer derives its name from the construction of its steering:gear. Amongst these trailers there is the end-tipper, the either-side tipper, the three-way tipper, and any other sort of tipper that can be ment:oned, or is likely to be demanded. At Olympia there will be exhibited five selected examples of this company's products, including an end tipper on a Daimler, a cesspit emptier, a Fordson trailer, an Eagle-Ackerman trailer, and an all-steel chassis equipped with turntable steering.

A Forward Dash Type Fiat.

TFiat programme includes, besides a taxi, chassis for 1 loads of 10-cwt., 15-cwt., 1-ton, 30-cwt. and 31-tons. The 10-cwt. chassis is an entirely new model, and will, therefore, possess the-greatest interest.. It has a four-cylinder 65 mm. and 110 mm. bore and stroke, which transmits to a four-speed gearbox through a multiple-disc clutch, the engine, clutch and gearbox comprising one unit. The final drive is by spiral-bevel gears, and the equipment includes steel wheels and pneumatic tyres. The 30-cwt. model is the 15-ter chassis redesigned and modernized. The general specification is the same AS that

quoted above, but, the engine is a four-cylinder, 100 mm. and 140 mm. bore and stroke.

Fiat commercial vehicles can be obtained with the usual complete range of bodywork, including public service vehicles and motor coaches. In this connection the 16-seater pay-as. you-enter bus, on a 15-ter chassis, is of particular interest. Fiat Motors, Ltd., 43-44, Albemarle Street, London, W. 1.

'A New Six-ton Foden.

THE Foden steam wagons, for 3, 4, 5 and 6-ton loads, will constitute the 1924 production scheme at. Sandhach. The general details of these wagons are, we believe, so well known that there is hardly any need for us to enumerate them, and if we do so it is for the benefit of readers who may require this information.

The outstanding feature of their programme is, of course, their new 6-ton model, which has now been on the roads nearly a year, and may, therefore, be said to have settled down definitely as regards both general outline and the detaila of this specification.

The features of the 6-tonner are its specially large firebox and ample heating surface, necessary in order to afford the increased weight of steam needed for the 4k-in. and 7-in. by 7-in, compound engine, at the working pressure of 220 lb. per square inch. Three speeds are provided, and the front axle IS of the' Ackermantype. The foot brake takes effect on the rims of the rear wheels, and the hand brake on a drum mounted on the rear axle.

At Olympia there will be two of these 6-tonnes's shown, both with long platform bodies, and also a 5-ton wagon, equipped with three-way tipping body, which is particularly' suitable for use in connection with municipal work and road making.

Foden, Ltd., Elworth Works, Sandbach.

Efficient Lubrication System on Foster. TIET-n-J.TAm FOSTER AND CO., LTD., are continuing V V during 1924 to make the well-known Foster lines of steam tractors and wagons. The 5-ton steam wagon, of which one example will he shown at Olympia., is perhaps the most interesting Foster machine so far as the bulk of our readers are concerned. It is an overtype chassis, with spur type of gearbox and final drive by roller chain. In the ordinary way it is equipped with two changes of gear, but a third can be supplied as an extra if required. The brakes take effect on drums in the rear wheels and are adequately compensated.

An interesting feature of this wagon is the special type of oil pump, which is fitted to all Foster steam engines ; its outstanding point is that the delivery stroke of the pi mp 'plunger is made at high speed, thus eliminating leakage, which occurs. so. frequently in the case of an ordinary pump where the speed of the delivery stroke is made so very slow. William Foster and Co.. Ltd., Wellington Foundry, Lincoln. B22

Road-making Machinery by Fowler's.

T1OWLER'S will be making, in 1924, their usual complete line of steam road vehicles, including the -a-ell-kriowe Tiger tractor. The firm's programme also comprises a comprehensive list of road-snaking machinery, as well as a complete line of power-farming implements and machinery of all kinds.

The Tiger tractor is designed to come within the limits of weight set by the Motor Car Act. It is fitted with an arrangement whereby the compound engine may be instantly converted to a high-pressure double-cylinder engine, with independent exhaust for each cylinder.

This firm will be exhibiting examples of its products at the Public Works and Road Transport Exhibitian, including two types of steam road roller, a scarifier, a compound and convertible steam tractor and road roller.

John Fowler and Co. (Leeds), Ltd., Leeds.

The Garner Bus-van Improved.

J'ENRY GARNER, LTD., is still sticking to the onemodel programme which has been typical of that firm now for some years. That model, described as No. 15, has a gross load capacity of 47 cwt. It is aequipped with fourcylinder engine of 32 in. by 5 in. bore and stroke. A multi. plate dry-disc clutch and three-speed-andlreverse gearbox, transmitting to a double-reduction-type 'rear axle, of which the final-reduction gear is embodied in drums on the rear wheels, comprises the transmission mechanism of this chassis. The suspension embodies semi-elliptic springs, both front and rear, and the brakes both take effect on drums in the rear wheels. This particular chassis, besides being suitable for loads of the weight already enumerated, is also particularly adaptable for use as a bus, and, as a matter of fact, the Garner Busvan, which is a special type of vehicle easily converted for use either as a passenger vehicle or for goods van, or, in case of need; for both services at one and the same time, is a prominent feature in connection with this chassis.

Henry Garner, Ltd., Moseley Motor Works, Birmingham.

Guy Petrol Chassis.

THE principal Guy commercial motor models will be exhibited at Olympia, and the exhibits at this company's stand will be typical of their products. The complete programme embodies : -A 15-20-csvt. chassis, which has a 4-cylinder 85-mm. by 110-mm. engine; a 25-cwt. chassis, which la's° has a 4-eylinder 'engine, . 88 mm. by 120 mm. ; a 30-ewt-, with engine the same size as that of the

25 cwt. ; a 2-tonner and also a 24-=tonner, both with h.p. engines of 4-cylinders, 4-in, by bore and stroke. There is also a 3-tonner and a special passenger chassis, both of which embody the same 25 h.p. engine. At Olympia these will be exhibited as follows :—

The 15-20-cwt. chassis with a box' van; the 25-cwt. 'as a 150-250-gallon turbine motor fire-engine; the 30-cwt., as an 18-seater saloon coach; the %-tonner equipped with a 25setter onesman-operating bus body, with' one door at the front. There will be an example of the special passenger chassis' which will be equipped with a 20-seater motor Coach body, luxuriously fitted out, and designed, as regards its appearance, as nearly like a touring car as may be, and having an exceptionally low loading platform.

The Guy electric chassis, although still an important feature of the company's programme, will not, so far as present intentions go, be shown at Olympia.. Guy Motors, Ltd., Fallings Park, .Wolverhampton.

A Self-tracking Garrett Trailer,

G.ARRETP AND SONS, LTD., have a programme embodying electiic chassis as well as both outstanding types of steam wapitis. They also make self-tracking trailers. At Olympia will be ssen models of the under-type wagon and of trailers.

• The general specification of Garrett wagons is widely known. Brief reference, therefore, need only be made to the undertype, as representing the new model so far as this firm is con

cerned. It is made for 4-6-ton loads, and its principal features are the use of roller bearings throughout the chassis; provision for easy access to the boiler tubes, so that they can be readily cleaned arid, if necessary, withdrawn without having to take out any internal part of the boiler. The transmission embodies a two-speed gear, and the final drive is by

a pair of roller chains. '

The self-tracking trailer is also mounted on roller bearings throughout, and being of light but strong construction requires a minimum of power to haul it. It has the additional feature of presenting a low loading line, and is adapted to he hauled in either direction.

The range of electric vehicles manufactured by this firm has an inclusive capacity of from 30 cwt. to 6 tons. The 2-1-, 4 and 5-tonners are each made in two chassis lengths, the shorter of the twe in each case being 'adaptable for use as a 'tipping wagon.

'Additions to the Hanford Programme.

THE 'Hanford programme includes a 35-cwt, chassis with 25 h.p. engine of 100 min. and 140 mm. bore and stroke, with three speeds and 'reverse gearbox; a four-tonner with 32 h.p. engine of 110 lam. and 140 mm. bore and stroke, equipped with a four-speed-and-reverse gearbox; a five-tonner with 40 h.p. engine of 120 mm. and 140 mm. bore and stroke respectiVely, equipped with tt four-speed-and-reverse gearbox; and a 10-ton six-wheeled—tractor-trailer combination vehicle with the same engineand gearbox as that fitted to the fit-etonner. The last-named model is equipped with Westinghouse General Vehicles in Considerable Variety.

THE General. Vehicle Co.'s programme of production of the well-known electric vehicle chassis is such as to cover practically all sizes from one to five tons inclusive. That was its programme for last year. This is now supplemented by the addition of .six-wheeled vehicles of the tractor-trailer combination type, and of which there are three models..available—a 4-tonner, 7-tanner and 10-tontier. As regards the 4-tanner this is particularly adaptable for house and trade refuse removal, the loading heightbeing only 4 ft. approximately. A third line is the manufacture of industrial trucks -and tract-qrs.

All of the six-wheelers are equipped with Westinghouse air brakes. The turntable on the tractor portion of the combination is what is known as the Martin Rocking Fifth Wheel, which has a quick-release mechanism, which is con_trolled from the driver's cab, so that he can withdraw the tractor from its trailer without leaving his seat.

They also make industrial trucks of 2-3-tons capacity, as well as an industrial tractor of 10-tons tractive capacity, 'designed to be used either on rails or on roads, and in connection with shunting of railway wagons.

Leyland Lorries and Trojan Vans.

JEYLAND chassis are now catalogued in groups, whick A enables us to present that company's 1924 programme completely ewithin such space as is available.

The groups may be enumerated as the 2-ton, 3-ton, 4-ton, 5-ton and 6-teln. The 2-ton embodies four cylinders, 41-in. by

5-in.-engine and worm-driven rear axle. It is made in five types

—standard, tippee and three passenger models. The differences between the first and second of these relates to the overall length of the chassis, and in the others in the wheelbase. similar grouping is included under the heading of 3-tonner, and of the five models included three have the same engine as that quoted for the 2-ton. A fourth one, of the passenger type, has a 4i-in. by 5-in, engine, while a fifth, designed for overseas use, has a 41-in. by 6-.m, engine and a bevel drive. Included in the 4-ton group is an R.A.F. subsidy rebuilt chassis. The 5-6-tonners are sold as " standard " and "tipper" The passenger models of the various groups are reclassified aitiording to seating capacity, and, as motor coaches, afford conveyance for from 18 to 33 passengers, and as single-deck busee from 20 to 40 passengers. In additiou to the machines already enumerated there are, of course, the Leyland fire-engines, made in three sizes, hay ing capacities of 300-400 ,gallons, 500-700 gallons and 7001,000 gallons. Finally' there are the steam wagons, made in 5, 6 and 8.ton sizes. Mention must also be made of that un-Leyland-like vehicle the Troja-n, which is a light van of 5-7-cwt. capacity, with a 4-cylinder 2-stroke engine and epicyclic ehange-speed. gear.

The design of both engine and transmission of this vehicle is very ingenious and embodies many unorthodox features. Leyland Motors, Ltd., Leyland, Lanes.

Longframe Six-wheeler Construction.

MHE ingenious and novel type of six-wheeler, "which is known as the Longframe, is being introduced into this country by the Longframe Six-Wheeler Construction Co., of Copenhagen; Denmark, and an example will be shown at Olympia. The details of this machine may be briefly described. as follows :—The frame of the chassis is continued aS one piece rearwarclly to the full length which is required for the completed vehicle. The rear main axle is a duplicate of the front axle, complete with steering gear, which is connected up to the tractor, so that both front and rear axle are all steered. A simple framework -couples this rearmost axle to the main frame at a point somewhere about the rear end of the springs of the middle axle, the connection there being a pivotal one. Further support for the main frame is afforded about halfway along this subsidiary chassis. An advantage of the design is, of course, that the complete vehicle may be manoeuvred travelling either forward or reverse, owing to the fact that the steering gear is designed for operation in either direction, •

It has a four-cylinder engine, 69.5 mm. and 102 nun. bore and stroke, three-speed gearbox, and worm-drive rear 'axle. The same chassis is also used as the basis for a useful type of traveller's van, with two seats in front and a box in the rear, designed to carry approximately 6 cwt. of samples or other goods.

Morris Motors, Ltd., Cowley, Oxon. A New Model Mann.

ivrANN'S PATENT STEAM CART and WAGON CO., _a_LLTD., make steam wagons for 3, 4, 5 and 6-ton loads. In general design these wagons are closely related to the familiar overtype, but are, nevertheless, in a class by them.. selves on account of their ingenious arrangement whereby the driver sits by the side of the boiler, and can hinise.f stoke aud drive with convenience.

As one outcome of the arrangement of the driver's cab,

all the transmission gearing is disposed within the frames of the chassis. It is designed to afford three changes of gear. The final transmission is, as usual, by a substantial single roller chain to a differential on the rear axle. Two independent mechanical brakes are fitted, one—the foot brake— taking effect an a drum on the intermediate layshaft, while the hand brake operates on drums in the two rear wheels. Both the road wheels are quickly detachable for purposes of tyre replacement. At. Olympia the Mann wagon will be represented by a gully-emptying machine and a 6-ton wagon with platformtype body.

A Maudslay Subsidy Chassis.

THE Maudslay programme for 1924 comprises seven chassis designed for conveyance of goods and two for passengers. The goods vehicles have capacities of 13 cwt., 2 tons, 3-4 tons, 4-5 tons, 5-6 tons and 7 tons. There is, in addition, a special 3-4-tonner on short wheelbase. The 13-cwt., 2-ton and 3-4-ton models are worm driven. The special 3-4-tonner and the larger sizes have all double-reduction rear axles. All models have four-speed gearboxes and cone clutches, with the exception of the 13-cwt. and 2-ton chassis, which embody single plate clutches, The passenger models are alike, except as to engine size, the small one having a 32 h.p. engine of four cylinders with a bore and stroke of 41 ins. and 5 ins.; the other a 46 h.p. engine of four-cylinders, with a bore and stroke of 5 ins. The 3-4-ton special model and 7-lousier are both of the evertype, i.e., they are both arranged with the driver's seat at the side of the engine. The outstanding features of the Maudslay chassis are, of course, its robust double-banjo forged rear axle and its special engine with overhead valves. The 30-cwt. machine, we are informed, complies in all respects with the War Office specification, and is equipped, as standrd, with pneumatic tyres on disc wheels.

The Scammell—the Tractor Lorry Pioneer. rilHE Scammell programme may be summed up in one word —" six-wheelers.''

Features of this pioneer English machine are the double springing of the rear axle on the tractor and the employment of heavy i/oiler chains for the final drive; also the simple method of working the brake, embodying a bell-crank lever attached to the tractor turntable and operated by means of a pin which passes through the axis of the turntable, and

bears directly on to a smaller bell-crank lever mounted an the trailer.

The power unit is a, four-cylinder overhead-valve engine of 5-in. by 50n. bore and stroke. The most recent improvement is the new design of turntable, pressed in one piece from a sheet of steel, this one single pressing replacing no fewer than 200 separate parts used in the former design.

Saurers Now Make Four Models.

SA.URER chassis are now made in four models for net loads of 2, 3, 4 and 5 tons respectively. All of them are the same general specification and -embody the same special features. The engines, which are four-celinder units, embody monobloc-cast oylinders, designed so as to be easily -removable by one man. Each is equipped with mechanism whereby the engine i4 capable of being used as an effective brake. Engine, clutch and gearbox are to all intents and purposes one unit, and the gearbox provides four speeds forward and a.reverse. The final drive is by -propeller shaft to a bevel gear rear axle. Amongst the interesting features may be mentioned the "engine Inbricatien by a Owlet system involving two pumps. The ignition is automatically retarded when the starting handle is engaged. The camshaft is balanced, the crankshaft runs onball bearings, and the carburetter is heated by exhaust gas, the _amount of heat transmitted being constantly under the control of the driver. All the brakes' are adjustable, while the chassis is running, by means of easily ae-cesaible hand wheels. 'The formation of the rear axle is such that the rear wheels slope away from the chassis: so that the twin tyres make better contact with a cambered road surface.

At Olympia it is anticipated that, in' addition to a polished chassis, there will be a 5-ton model equipped with patent three-way tipping body, a 3-tonner on which will be mounted special sanitary dust-cart body, and the actual 5-ten vehicle which was submitted to a test by the R.A.C., from which it emerged so successfully.

MHE Yorkshire Patent Steam Wagon Co.'s plans for pro duction during 1924 remains unaltered, so that the steam ` wagons made by this firm will present the same well-known features as has been the 'case during the past year. The programme embodies three models—a 3-tonner, a 6-tonner-both being chain-driven—and a 6-7-tonner with live ails drive and totally enclosed transmission. The outstanding Yorkshire features are, of course, the transverse fire-tube boiler, which has the advantage that its water level is not appreciable altered by the circumstances that the wagon may be ascending or descending a steep hill, and its engine. The latter is a vertical high-speed, totally enclosed unit, and is mounted behind thd driver's seat. In the ordinary chain-driven models, as well as in the new live axle maehine, three speeds are .provided. The final drive im the case of the Elie axle chassis is by double reduction, bevel and spur gears, mounted in the centre of the 'fully floating rear-axle case. • At Olympia this • concern will be showing -one of the 7-tc.nners, upon vihich 'will be mounted a mechanically operated end-tipping body.. They will also, stage a 3-ton wagon designed forthe collection of house refuse, this also being equipped with a .mechanically end-tipping body, but having the bottom and sides -of the body lined with sheet steel.

Vulcan Advances in Body Construction. Vulcan Advances in Body Construction.

TEM Vulcan commercial vehicle programme for 1924 embodies three models, having capacities of 20-25 cwt., 30 cwt., and 40 cwt. respectively In general specification these three models are closely allied—in fact, it may be said that the main difference is in respect of tyre equipment, -the smaller model now being as a general rule shod with pneumatics, whilst the others are equipped with solid band tvres, but may have pneumatics on demand. This general specification covers a four-cylinder engine, having side-by-side valves,

pump water circulation, and trough lubrication. The clutch is a cone faced with Ferodo fabric, and it transmits through a four-speed-and-reverse kgearbox, behind which comes an open propeller shalt and worm-driven-rear axle.

The suspension of this chassis embodies semi-elliptic springs, both at front and Tear.' " The brakes are so arranged that the foot brake takes effect on a, druin behind the gearbox, and the, hand brake operates on the rear wheels.

The body equipment, which is available in connection with these chassis, is most comprehensive, both as regards goods

and passengers. A typical example of the latter is a 14seater omnibus on the 90-25-c,wt. chassis; admirably designed for the Conveyance of hotel guests .to and from the station, ok for similar•purposes. The 30-cwt. chassis conveniently accommodates a 20-seater bus. A 26-passenger bus can be fitted with ease upon the 2-ton chassis.

At Olympia there will be shown examples of both motor coach and bus bodies, as wefi as the three-way tipping wagon, and a special vehicle emstrueted to carry timber. The Vulcan Motor Engineering Co., Ltd., Cross-ens, Southport.
