OLYMPIA: WHAT MAKERS WILL EXHIBIT.

A Review of the Complete Range of Petrol, Steam and Electric Vehicles to be Displayed at The Commercial Motor Exhibition.

OUR aim in this and the following pages is to present a simple, yet so far as is possible, complete survey of the vehicles, chassis, tractors and municipal appliances which will be displayed .at Olympia for nine days from and including Thursday next. The commercial motor industry has been encouraged by the gradually improving demand of the past two years for new vehicles (in particular, passenger carriers) embodying advanced lines of thought, and we think that the general consensus of opinion, at the Show and after, will be that modern design embraces very substantial improvements. Considerable interest will be evinced in this year's Exhibition, not only for the reasons above outlined, but also because of the growth in the transport industry with its consequential greater number of owners and users, and its increased number of vehicles.

The general trend in chassis• intended for bus work being towards a lower frame level, following the lead set by the N.S. chassis designed and produced for the London General Omnibus Co., Ltd., by the Associated Equipment Co., Ltd., it will be found that this is a feafure of the products of a number of the prominent makers.

ALBI ON. Stand 95 Albion Motor Carp Co., Ltd., Scotstoun, Glasgow.

AVERY comprehensive exhibit will be staged by this oldestablished and popular commercial-vehicle company. There is little doubt that the new 30-60 h.p. bus, designed to carry 30 passengers, will be one of the most outstanding features of the Show; The exhibits will be six in number, the foremost, of course, peing thenew bus, which is of the low loading-line type and rmbodies many interesting points. The chassis frame slopes from the radiator to the back of the gearbox, from Which it runs parallel to the ground. It is then upswept over the rear axle and drops again behind it to a level 6 ins. below that of the centre part of the frame. The transmislsion is in practically a straight line from the crankshaft, the rear axle being of the underneath worm type. With the exceedingly long wheelbase of 16 ft., it can well be understood that this machine affords comfortable .transport for its occupants. The body is of the rear-entrance saloon type, constructed entirely in accordance with the proposed regulations of the Ministry of Transport.

.Another exhibit will be the 18-seater Viking motor coach, Painted in a handsome shade of peacock blue. This is also equipped with the new 30-60 h.p. engine. The petrol tank is now carried on the off-side frame member, and the spare wheel at the rear.

Coming to the commercial models, there will be the 30-cwt. W.D. subsidy model. This; is built in accordance with the specification for subsidy requirements.

Further interest will be created by the attractive exhibit of the 24 h.p. 2-ton petrol-can-carrying lorry for the AngloAmerican Oil Co.

For a business which requires a vehicle of the boxvan type an interesting exhibit will be found in the form of the standard 24 h.p. 30-cwt. chassis. The vehicle is equipped with solid tyres and has an oak body frame with wooden and steel panelled roof and sides, in accordance with the latest practice. A door leading into the interior is fitted behind the driver, thus facilitating the kindling of parcels, etc.

Finally, there will be a 4-ton van of the latest type, with a 32 h.p. engine, having the driver over the engine, making it suitable for bulky loads. The bodywork of the exhibit will be of unusual deSign. as it has large roller shutters at each side, and the rear is fitted with a similar shutter extending down to the tailboard.

A.E.C. Stand 80 Associated Equipment Co., Ltd., London, E.17.

A E.C. vehicles require no introduction whatever to those who have any knowledge of the commercial motor world. Four exhibits will be shown on the company's stand, these comprising a 2-ton lorry, a 30-seater bus, a 6-ton forward-drive lorry and a 50-seater covered-top-deck provincial bus. In addition to these, of course, there will be other chassis of A.E.C. make, bearing bodies made by various coachbuilders to be found under the roof of Olympia. The 2-ton lorry will be shown equipped for the transport of petrol cans. This has a four-cylinder engine, an inverted cone clutch, four-speed gearbox, incorporating ground gears, D16

and an overhead worm-driven axle. This is an extremely useful type of vehicle, which has proved verY popular since its introduction a few years ago. The next exhibit will be a 30-seater bus, with front-wheel brakes, known as the Renown. This has a driver-beside-engine layout, the driver's compartment being well shielded from the weather ; the passenger entrance is on the near side at the rear.

The 6-ton forward drive lorry to be exhibited has a driverbeside-engine position and is a modification of the 4-5-ton model, considerably strengthened. Various types of axle reduction are provided, but with a ratio of 7+ to 1 cutup the vehicle is capable of 16.3 m.p.h. The four-cylialler A.E.C.

engine develops 45 h.p. at 1,000 r.p.m. All components, such as valves, pump, magneto, carburetter and oil filler, are on the near side of the engine, immediately accessible by lifting the halt-bonnet; a tubular guard is fitted in front of the radiator.

The clutch is of the inverted cone type, lined with Eeroclo, the thrust being self-contained when the thrust is in ; an adjustable stop is provided. A four-speed gearbox is standardised, the universal joints being of the fabric-disc type on the front eardan shaft and hardened-steel joints in waterproof grease-tight cages on the rear shaft. Taper .roller bearings are used for the road wheels, and the worm transmission gear is carried in a detachable easing ; foot and hand brakes operate direct on the rear wheels and are of the internal-expending type. Worm-and-wheel steering operates on taper roller bearings.

Unusually substantial side members constitute the frame of the vehicle, the channels being parallel from end to end and fitted with stiff cross-members.

The chassis employed for the 50-seater covered-top-deck provincial bias is similar to that of the 6-tonner. This is an improved and simplified design of the 1925 model, the flitch frame being replaced by a pressed-steel one. The clutch and brake-operating gear have been redesigned, and the torque rod is no longer employed, the rear springs being bolted direct to the axle casing ; the banjo forging is retained. ATKINSON. Stand 120 Atkinson Walker Wagons, Ltd., Frenchwood.Works., Preston.

TTNIPLOW engines are a feature of the Atkinson design, L.) and one of their ti-ton models will be shown at Olympia, fitted with a special covered body. In addition, there will be a boiler with the top outer shell removed to show the interior construction and workmanship ; also a Unitlow engine, so arranged as to make clear the simplicity and safiall number of parts employed. A front axle will be demonstrated,. complete with journals and pivots, to set forth the accessibility of the working parts. Further, there will be a rear axle, in which the action of the differential and brake gear can clearly he seen.

Two extremely -interesting working models of the engine valve gear and the Tinitlow piston in section will be shown to reveal the functioning of the items in question.

In general the design remains much as it hag been in. recent years, but, principally with the object of enabling higher average speeds to be obtained, the engine power has been appreciably increased, and the boiler capacity is now much larger. Chain final drive is used in all eases.

Atkinson wagons lend themselves to a variety of purposes, such as the carrying of vacuum gully-emptying plant, street sprinklers, street sweepers, tar sprayers, dust-collecting wagons and combination vehicles for municipal purposes.

AUSTIN. Stand 116 The Austin Motor co., Ltd., Longbridge Works, Birmingham.

FOUR exhibits will be found on the Austin Co.'s stand, these consisting of examples of the 7 h.p., 12 h.p.,. 20 h.p. chassis and the tractor. Dealing with the smallest model first, the 7 h.p. model is well known as a light car of high efficiency, and its performance as a commercial van is no less satisfactory. The four-cylinder water-cooled engine has a detachable head and a roller-bearing crankshaft. Transmission is by single-plate clutch and three-speed gearbox to a three-quarter floating rear axle ; four-wheel brakes are provided, together with electric lighting and starting, electric horn, and shock absorbers. The model to be exhibited will have a body built by Startin; Ltd., and is built to carry a load of 24 cwt. The next vehicle in order of engine power is the 12 h.p. model, of whie.h two.will be exhibited, a delivery van and a traveller's sample car. The latter is a two-seater vehicle provided with every comfort and long and continuous journeys, and the goods compartment has two doors and the necessary shelves.

Two 20 h.p. models will also be shown, one being the ambulance and the other a delivery van. Startin, Ltd., are undertakifig the coachwork of both exhibits. In the case of the ambulance, accommodation is provided for two stretcher and four sitting cases, the interior being appointed with all necessities. Long, undersIung springs, shock absorbers, and large-section tyres assist to give the utmost comfort to the occupants. The delivery van is a handsome and efficient vehicle, and particularly suited for fast delivery work.

Roth the 12 h.p. and 20 h.p. models have four-cylinder engines constructed in a unit with the gearbox, and springing is by semi-elliptics all round.

The Austin tractor has steel-disc wheels, and the model to be shown will have rubber tyres, which enable it to he used for road haulage purposes; the gearbox has three forward speeds and reverse.

AUTO-TRACTION. Stand Ti

Minerva Motors, Ltd., Chenies Street, London, W.C.1.

WO new bus chassis are features of the Minerva Motors products for 1926. 'Three exhibits are to be arranged on the stand—namely, the model C.R. 20-26-seater, a 30-seater chassis and a 6-tan tractor with a bare trailer chassis.. The passenger models each have a similar specification, on the following lines :—A 30-50 h.p. Minerva sleeve-valve fourcylinder engine, of 110 mm. bore and 140 mm. stroke, having a governor driven by shaft from the crankshaft. The general layout of the. sleeve-valve mechanism is identical with that used for many years on private cars, but, of course, the engine has been specially designed for commercial work.

The four-speed gearbox is in one with the engine, being suspended in. the frame at three points. Gear control is by a centrally placed lever and the drive is by cardan shaft with three universal joints, the two forward ones being of the flexible-disc variety. The rear wheela are carried an a spiral-bevel live.axle, and have internal and external brakes operating on the wheel drums. The -front axle is of exceedingly heavy,seetian and the front-wheel brakes are supplied

as a standard fitting. Both these chassis are of the lowframe type.

The Auto-Traction tractor lorry is of the six-wheeled type, and embodies an automatic coupling and swinging front axle to the trailing unit. A sleeve-valve 20 h.p. engine is fitted as are a four-speed gearbox and a three-brake system.

BEAN.. Stand 92

A. Harper, Sons and Bean, Ltd., Dudley, Worcs.

ONE type of -Chassia 'will be displayed on this makers' stand, this'being the 20-25 cwt. model, carrying vari

ous typeS. Of coachwork, nit lead capacity is actually' 37 cwt., which permits the use "Of:a sturdy body while retaining a large carrying capacity. On its top gear of 6.41 to 1 high travelling speeds can be obtained, and the fourspeed gearbox enables the stiffest of country to be negotiated with comparative ease. Front-wheel brakes can be provided on any model as an extra, and the merits of these are now widely appreciated, particularly for passenger purposes. Straight-sided pneumatic tyres are standardized, but cushion tyres are fitted if desired.

The following models will be on the stand :—The chassis with front-wheel brakes; an open lorry with hinged sides and tailboard ; a van with straight-sided pneumatic tyres; an ambulance with special extras in equipment and fitted with double stretchers; a 14-16-seater char-it-banes fitted with front-wheel brakes—the rigid side-curtains make this vehicle a cosy touring coach in inclement weather—and finally, a 14-seater light onulibus running on straight-sided pneumatics.

Accessibility is a feature of the Bean chassis, an instance being provided by the magneto which is mounted on the off side of the engine parallel with the top of the cylinder block ; below this is the dynamo. Either the make and break of the former or the brussh gear of the latter can be reached without difficulty.

BEARDMORE. Stand 100 Beardmore Motors, Ltd.„ 112, Great Portland Street, London, W.1.

TAXICABS, 30-cwt. chassis, box vans, coaches, omnibuses and delivery vans comprise the range of vehicles to be shown by the Beardmore concern. Dealing with them in order, there will be the Beardmore " 15 " taxicab, details of which are well known and include such items as pomp cooling, forced-feed lubrication, cone clutch, bevel-gear axle and steel: wheels. The bore and stroke of the engine are 80 ram. and 120 MM respectively and the top-gear ratio is 4.28 to 1. The brakes are both situated in the rear wheels and act on separate drums. Semi-elliptic springs are standard. The coachwork is of the three-quarter landaulet type, seating four persons.

The 30-cwt. chassis is to he shown in strippea form. A worm-driven rear axle is standard on this type of vehicle as a contrast to the taxicab. A metal-panelled boxvan will be exhibited on the 30-cwt. model, and it will have folding doors and a sliding door behind the driver. A handsome 14-seater char-à-bancs will be displayed on the same chassis, as will a 16-seater one-man bus body fitted with sliding windows and an emergency rear door. A similar bus will also he on the stand, but painted brown instead of blue. Both have sliding windows and emergency doors at the rear.

The final exhibit is to be a 15-cwt. delivery van, similar in many respects to the taxicab chassis, but the gear ratios, springing and so forth, are slightly different. Electric lighting and starting are provided and the vehicle is handsomely, finished in blue, BLIELLIET: Stand 111

Automobiles M. Barbet, Richmond Bridge Works, Cambridge Road, Twickenham.

NO FEWER than eight exhibits will be found on the Berliet stand, a very comprehensive range indeed and one well known to users of commercial motors. Starting with the smallest model,we have the 15-cwt. boxvan, which has a four-cylinder engine rated at 15.9 h.p., with a gearbox mounted at the rear end of the engine. The handsome hors-an is panelled in Sundeala on ash framework.

A medium-sized passenger vehicle is the 14-seater saloon bus mounted on the 20-cwt. chassis. Central control is provided and the final drive is by overhead worm. A lighting and starting set is included. The 14-seater body is of the Berliet type, with coach-type entrance door and a rear emergency door. On each side are four windows, three of which are of the drop pattern. The seats face forward and are upholstered in leather cloth. The same type of chassis will be shown as the basis of a Local Government Board ambulance. ,

Conforming with modern ideas of pasSenger transport is the 14-seater low-loading chassis of 30-cwt. capacity, an example of which will be seen at the Show with a motorcoach -body. A double-rediactiOn rear axle is fitted to this model, also pneumatic tyres and electric, lighting and starting. There are three doors on the near side and a driver's door on the off side. The hood is of the one-man type and the side curtains open. with the doors.

Shown in chassis form will be the 3ii-cwt. model, which has a worm-driven rear axle; also electric lighting and starting. Another exhibit of this type will be an 18-seater-saloon bus body equipped for one-man operation, having an emergency rear door and drop windows.

Of tip-to-date design is the 26-seater saloon bus, the basis of which is the 50-cwt. chassis. The engine of this vehicle has overhead valves operated by push-rods. The entrance door is situated so that control is by the driver only.

The final exhibit will be a three-way tipping body mounted on a 5-ton chassis, which has final chain drive—an example of the retention of this type of transmission for heavy-duty work. The tipping gear is operated by the engine and the body has a steel-lined floor.

BRISTOL. Stand 37 The Bristol Tramways and Carriage Co., Ltd., Tramways Centre, Bristol.

FORWARD driving positions are employed on both the Bristol models. Originality in mechanical layout • is especially noticeable in the larger model, although the smaller vehicle in no wise slavishly coPies conventional practice. Seven exhibits will be'found on the stand, three relating to the 2-ton model and four to the new passenger vehicle which was recently described in full in The Comm.ereial Motor. The passenger model is, of course, of the special law-loading type.

Shown as a 20-seater bus will be the only complete vehicle exhibit of the 2-tonner class; other items in this connection will be a 2-ton chassis and the various units employed in the construction of this model.

A 32-seater single-deck bus body will be mounted on the larger chassis, although, of course, this is designed also to take double-deck bodies. The actual frame level is 2 ft. 1 in. from the ground up to the point where the arch occurs, whereas it is only 1 ft. 9 ins, to the rear of this. The frame members are parallel in plan, but are inswept just behind the clutch. An unusually deep section channel is employed for the aide members, the only deviation from the horizontal D18

being at the point where he members are upser€4pt to clear the rear axle.

Springs are self-adjusting to load through the medium of cam-shaped brackets faced with hard brass, so designed that, us the load increases, the straightening of each spring reduces its effective length, thus automatically stiffening it. A four-cylinder engine is provided, this .developing some 80 b.h.p. at 2,000 r.p.m.; the latest practice is revealed in the use of Duralumin connecting rods and aluminium pistons. Rubber insulators take care of the body load and rebound, comfort being one of the most important factors in the design of the Bristol chassis.

From the upkeep point of view the vertical position of the magneto and dynamo is interesting, and the carburetter is accessibly located. Inspection of the mechanical details can best be made by referring to the stripped chassis which will be.shown, also to the separate engine and gearbox units.

CHENARD-WALCRER. •Stand 75 Archie Simons and Co., 94, Great Portland Street, W.1.

THESE well-known commercial vehicles of French origin will be represented at the Show by a 10-ton tractor and two trailers, each of 5 tons capacity. So far as the tractor is concerned, it is known as type B 10, and is equipped with a four-cylinder engine of 80 mm. by 154) ram. bore and stroke respectively ; it has thermo-siphon cooling, magneto ignition and pump lubrication. Transmission is through a four-speed-and-reverse gearbox and the tyres are 880 mm. by 120 min. Michelins. A separate lighting and startins-6 installation can be provided for the additional sum of 130,

these being of the separate-unit type. If the purchaser desires, a hoisting winch can be supplied as an extra for £70.

CHRYSLER. Stand 87.

Maxwell Sales Co., Ltd,, 212, Great Portland Street, London, W.1. •

TWO light delivery vans of Chrysler make will grace this stand at Olympia, one being finished in lead colour, from which stage, of course, it can be 'developed to suit the artistic requirements of its purchaser, the other being finished in a shade of blue.

Chrysler private cars, which are similar in many. respects to the commercial models, are well known for their many original features, and, although comparatively recently introduced to the British market, they have attained considerable popularity in this country. The engine is of the side-by-sidevalve type and is mounted at the front end on a transverse leaf spring; movement, however, is limited by fabric stops. At the rear end of the crankcase arms project, which are secured to brackets riveted to side members of the frame, but rubber thimbles separate completely each arm from its bracket.

A single plate elutch is used behind the engine, and it has no fewer than nine springs; behind this is the three-speedand-reverse gearbox, with an. open propeller shaft transmitting the power to a spiral-bevel banjo-type axle.

Lockheed hydraulic four-wheel brakes are used, and the transmission brake is of the mechanical type. BURFORD. Stand 105 H. G. Burford and Co., Ltd., 24, ,Haymarket, London, S.W.1.

THE makers of the Burford range of vehicles have been in business for many years, and as a result of their lengthy experience they can be expected to turn out a thoroughly satisfactory job, either for passenger or goods transport. An the exhibits on their stand are repeat orders from well-known concerns, or are duplicate vehicles to those which have been supplied to some of the most important users of commercial vehicles in the country.

The 20-seater 30 h.p. saloon bus will be shown, being part of a repeat order for ten constructed for -the Plymouth Corporation. The chassis is a 20-26-seater, one of its attractive features being the four-wheel braking system which was first exhibited by the Burford concern in 1921. The brakes on all four wheels are applied by the pedal, and a means of compensation is provided. Vickers, Ltd., are responsible for the, coachwork of this model, which is of the high order to be expected from such a company.

'A number of Burford vehicles has been supplied to the Great Western Railway, and a 30-cwt. N.C. chassis, fitted with a standard type of express-delivery van body as sold to them will be on view. The coachwork is by the Kenmont Motor Co., and represents the latest coachbuilding requirements of the Great Western Railway. The chassis has been materially improved for 1926, pedal gear, brakes, fan and other items having been slightly altered.

One of the 50--cwt. standard a-type chassis will be shown. This is used to form the basis of the Burford-Kegressc machines for which the War Office has placed a considerable contract with the makers: Hollow steei-spoked wheels are now standard on the 50-cwt. model, which add to the appearance, and may be relied upon to give satisfactory service. • Two more 30-cwt. vehicles will be on the stand, one constructed to the order of.Allen Liversidge and Co., Ltd., the other being a 30-cwt. N.C. chassis mounted on pneumatic tyres. In this form it has been a popular bus vehicle in Wales and Devonshire, where it has had some of the most difficult work with which to contend.

CROSSLEY. Stand 93 Crossley Motors, Ltd., Gorton, Manchester.

THRED interesting types of vehicle will be found on the stand of this well-known Manchester company, these consisting of a 15 h.p. van, a 25-30 h.p. lorry and a 25-30 h.p. Kegresse-track chassis. Intended for 15-20-cwt. loads, the van is an interesting departure for the Crossley concern, and it is intended to meet the demand for a light and speedy van capable of hard and long service. This vehicle employs a four-cylinder engine, with pump lubrication, thermo-siphon cooling, and a unit construction of engine, clutch and gearbox, final drive being by worm.

The 30-cwt. lorry has a high power-weight ratio, audit is specially suited for public-service requirements and for buses, ambulances and light fire-engines. The Indian Government employs a large number of these lorries, which have a fourspeed gearbox, controlled by the driver's right hand, disc wheels and Pneumatic tyres.

Combined with the Kegresse track attachment, the foregoing chassis is capable of tackling practically all conditions of country; its advantages for military purposes are obvious. The front portion of the chassis is virtually the standard 25-30 h.p. Crossley job, and it is driven exactly as an ordinary motor lorry, except for two auxiliary centrals for the Negresse two-sped gearbox and differential respectively, The main chassis features are a 86-in: by Kegresse track with two-speed gearbox, giving eight speeds forward and reverse, and a differential lock., which prevents loss of power 'due to varying surface conditions on each side of the vehicle.

CITROEN. Stand 107 Citroen Cars, Ltd., Citroen Building, Brook Green, Hammersmith, London, W.O.

FIVE exhibits will be found on the Citroen stand, all on the 11.4 h.p. chassis, but designed for many and varied purposes. The farmer's wagon will be one of the few exhibits of this type in the Show. The engine is thermosiphonically cooled assisted by a fan, and lubrication is by pressure feed• a lighting and starting set is provided. The body is of the Normandy type, having two seats in front, the cushion and back of the passenger scat being movable so as to give easy access to the rear compartment. Wooden body panels are utilised with a hinged tailboard and folding waterproof hood.

The boxvan body to be shown on another chassis has two seats in front and a door on each side, with side curtains; the spare whel is carried on the offside, and there is a double door at the rear giving a full-width opening. The load capacity is 7 cwt.

• Complying with the Scotland Yard regulations for taxicabs for London use is the 11.4 h.p. Citroen cab, the engine and gearbox being similar to those on the two foregoing exhibits, but the front and 'rear axles, springs, chassis frame, and transmission are specially designed for the purpose. Cash or deferred payment schemes are operative in respect of this model, an example of which will be on the company's stand. Popular interest is sure to centre largely in the CitroenKegresse platform vehicle, which consists largely of a standard chassis, but fitted with endless-band attachment, a radiator of larger capacity than normal, steering automatically connected to brakes on the driving pulleys, auxiliary twospeed gear in the rear axle giving six forward speeds and two reverse, a differential lock, and towing equipment. There are two seats in front covered by a hood and provided with a windscreen..

Another exhibit of this type will be provided with special attachments for the Propulsion of mowing machines, and is specially suitable for such institutions as golf clubs and for use on racecoursem, and so forth. A winch attachment is fitted behind the driver's cab. Two mowers are pushed in front of the vehicle and one is towed at the rear. A large frame extension projects forwards to give an anchorage for the two mowers: • . •

XAMPLES of the craftsmanship of this well-known com

4 pany will be reviewed with interest by users of all types of vehicle as their range is unusually comprehensive. Two new models are to be in evidence, one of which is a 30-cwt. and the other a passenger-carrying vehicle of the overtype, fitted with a 40 h.p. engine.

Dealing with the 30-cwt. model in the first instance, this D20

develops no less than 33 h.p. at 1,560 r.p.m. Lubrication is by pump driven from the camshaft, an external-cone clutch is fitted, fabric-lined, and adjusted by three external springs. Drive and torque are taken by a large torque tube provided with a spherical head. A feature of this model is the provision of a cushion-tyred spare wheel, although the four running wheels are furnished with pneumatic equipment. Self-starter and mechanically operated tyre pump are extras. A boxvan will be seen mounted on another chassis of this type, provided with cushion tyres all round. The driver's cab is furnished with a windscreen.

The familiar 4-ton worm-driven chassis will be exhibited with an open-type lorry body, having fixed sides and a tailboard—the driver's cab is provided with a windscreen. Transmission and rear-wheel brakes are standard equipment, both being of the internal-expanding type. A rear-entrance omnibus carrying 30 passengers is to form another exhibit in the same chassis category.

Another new model is the type E, having a low-load-line and a driver-beside-engine layout. The engine is a fourcylinder job, fitted with detachable heads—the cylinders being cast in pairs—developing up to 70 b.h.p., cooled by pump circulation ; a four-speed gearbox is provided, also an external-cone clutch and worm final transmission. The front and rear wheels are fitted with brakes operated by a servo mechanism, the hand-brake operating on the rear wheels only. Another exhibit on the same model will be a singledeck omnibus which can be reached by one step only, and carries 33 passengers; the driver's compartment is separate from the passenger section. On this stand will also be seen a 500-700-gallon motor fireengine fitted with a Dennis patent turbine pump and a 60-70 h.p. engine, a type of appliance for which Dennis Bros., Ltd., are justly famous.

EODEN. Stand 85 Fodens Ltd., Elworth Works, Sandbach.

TEIREE of the familiar Foden steam wagons will be shown at Olympia, all of them being of the 6-ton overtype class. One will be fitted with a special covered, body to the order of Messrs. Vernon, another will have an open platform body and the third will be fitted with an hydraulic three-way tipping body. Specially imposing is the covered model which is to be used for the transport of flour and similar materials.

The chaSsis specification remains much as in past years, the engine being of the two-cylinder compound horizontal type fixed on the top of the boiler and having D-shaped slide valves. The engine runs normally at about 400 r.p.m. The bore and stroke are 4 ins. and 61 ins, respectively, and both cylinders can be used with high-pressure steam in emergency. The reversing motion is of the ordinary link type. Power is transmitted by a pair of spur wheels, acting on a compensating gear, through a powerful roller chain to the rear axle. The last-named component is a solid steel shaft fitted with a differential on the off side and a locking arrangement is provided so that, when required, the drive may be taken equally by both wheels. The rear wheels run on bronze bushes and the front axle is of the solid pattern. being pivoted at its centre on a single laminated steel spring. The wheel bearinss in this case are of the plain type. Steering is accomplished by means of the warm gear actuating an adjustable chain secured at two points to the front axle. DODGE BROS. AND GRAHAM BROS. Stand 78 Dodge. Bros (Britain), Ltd., Willesden Lane, Park Royal, London, N.W.1.0.

SEVEN exhibits included in tne!range handled by Dodge Bros. in this country will lie:found on the stand, the models varying from .13-cwt. up. to 80-cwt. capacity. Dodge Bros. power plant is the standard unit in all the chassi-s, which confers the advantage upon users that spare part supplies are easy to obtain. First there will be the smallest vehicle,. inamely, the 15-cwt. Dedge Bros. chassis with a 11-24 hp. four-cylinder engine having Lynite pistons and a combined electric righting and starting outfit.. The chassis frame is built of 6-in. channel steel, and grease gun lubrication is provided throughout. A three-speed gearbox and a semi-floating spiral bevel rear axle are provided Mounted on the 15-cwt. chassis will be shown a; van which provides ample accommodation for a large volume of goods. The panelling is in special weather-resisting and non-splitting Sundeala board, which eliminates the -objectionable drumming frequently experiened( with metal panels.

Similarly mounted will be the Dodge Bros. travellers brougham. it is also constructed of ash . and has similar type panelling to that of the van.

Coming now to the Graham Bros. vehicles, there will be a 1.-tonner carrying a truck body described as model B.B. The Coachwork is of English manufacture, and the platform body has drop sides and an enclosed driver's cab.

A 1k-ton Graham Bros. chassis, model L.B.M. will also be shown on the 'stand. The design is generally similar to that of the 1-tonner, but the top gear ratio is 5.5 to 1, and metal spoke wheels are provided in order to cope with the heavier loads. An English van body will be exhibited on One of these chassis.

Different from the preceding example, principally in that it has dual rear wheels, is the model LB., carrying a saloon bus body on the 30-cwt. Graham chassis. The seats are arranged cross-wise down the length of the body, with a central gangway. Accommodation is afforded to 20 passengers, and patent fittings are specified for the drop lights, which ensure silence and self-locking.

FIAT. Stand 113 Fiat (England), Ltd., 43-44, Albemarle Street, London, W.1.

SEVEN exhibits of the well-known Fiat make will be found on the company's stand at Olympia, these comprising a chassis, no fewer than three box vans, a drop-sided lorry, and two passenger vehicles, one an all-weather coach and the other a 24-seater bus.

The smallest vehicle of the range is the 15-cwt. chassis, which has a four-cylinder engine, a four-speed gearbox and a worm-driven rear axle. The vehicle is equipped with pneumatic tyres, and electric lighting and starting is included. Mounted on this chassis will be the Windsor box-van body, which ha a tel panels and double rear doors, with a fullwidth windscreen. The 15-cwt. Regent boxyan is intended for high-class trades where appearance is of greater import-. anCe than in the case of the former van. This also is steelpanelled, and has a framework of steel and timber ; lull length running boards are provided.

The 25-cwt. boxvan, known as model 505F, is an innova

tion for this concern. Like its brethren, it has a fourcylinder engine with forced lubrication, the familiar type of pressed-steel Fiat rear aide, lighting and starting equipment. The foot brake is internal-expanding, and the band brake external-contracting on large drums in the rear wheels. Both.

brakes are rod-operated and compensated. On a similar Chassis will be shown a drop-sided lorry body, the sides and tailboard being hinged; the driver's cab is separate from the body, and is equipped with a windscreen.

Another new model to be shown is the all-weather coach designed for 40-ewt. working loads. This has a forced lubrication system, steel disc clutch, a new type of radiator, and a worm-driven rear axle of the floating type.. The all-weather coach body seats 15 passengers in addition to the driver. The head fitting is worthy of note, as it allows the coach to be used either as an open or as an entirely closed vehicle, Or with the head down and the windows up, or vice versa. There are three doors and a centre gangway, and leather upholstery is used for the seating.

The 24-seater bus body will be mounted on an example of the new model chassis designed for passenger serviee. This has a six-cylinder engine, the remainder of the details being, generally speaking, on similar lines to those of the coach previously mentioned. The body is of the one-man type. F.W.D. Stand 121

C. H. and L. 0. Smith, Canal Street, Nottingham. AS sole concessionnaires for the F.W.D. lorry, Messrs. Smith will be exhibiting .the latest type of 10.W.D. chassis, and a standard vehicle equipped with a tipping body of the general utility type. Further to these will be one or two sectioned' exhibits of particular interest to those who wish to study the mechanical-lay out of the F.W.D. in detail. Originally it was rated as a 3,tonner fot war purposes, but proved capable of heavier work; recently improvements have been incorporated which brought it up to modern standards. The chassis has been lengthened, which, permits the fitting of larger. bodies without excessive overhang. Three different

final-drive ratios can be supplied to suit the various require meats.

Instead of the transverse springing formerly fitted at the rear, there is now semi-elliptic springing all round, the rear ends of these springs sliding in slippers. The springs themselves have been greatly strengthened, the assemblies being increased to twelve leaves in the front and fourteen at the rear. The humps in the centre of the springs are now done away with, and the ofd triangulated torque rods have been eliminated. The engine has been modified, the inlet manifold having been redesigned to take a smaller carburetter, capable of giving greater mileage per gallon than some of the former models.

Splined ends have' replaced the former squared extremities of the axle shafts, and Ross earn-type steering is incorporated. The driving seat has been lowered some 4 ins., and set back 5 his.; to aid the driver the differential lock for the central differential is controlled by a lever mounted on the dash instead of by a handle on the easing. Four-wheel braking effect is obtained by mounting a brake drum—of larger dimensions for 1926—on the end of the transmission shaft, thus the braking strains are conveyed to all four wheels. Grease-gun lubrication is standardized. Another detail improvement is found in the increased size of the fan, this now having a large upper pulley, so that speed is decreased, although the amount of air expelled is considerably increased.

GOTFREDSON. Stand 76 Bonallack and Sons, St. George Works, Cable Street, Louden,

TWO. of the familiar Cotfredson chassis will be displayed on the Olympia stand of the COnCeSSiorovaires in this country, both being of long wheelbase. One will be shown as a chassis only, and the other as a 20-seater saloon bus. This vehicle will take a load of ao cwt. for use as a goods 'chassis. The wheelbase of the long model' is 12 ft., and it has a frame length DI 10 ft. behind the driver's seat. The engine is a four-cylinder of 31 ins, bore and 5-k ins. stroke, the cylinders being east in a block. The clutch and 'gearbox are of Brown-Lipe manufacture, the former being of 10 ins, diameter, and of the single pith type, running dry and fully enclosed ; ball bearings are, -used throughout. .Three speeds forward and reverse are provided by the gearbox, the mainshaft and spigot of which are equipped with Timken roller bearings, the layshaft runnine' on large ball" bearings. The front and rear axles are of the Timken type, a David Brown.. F.J. worm gear being used, however, in the rear axle. Timken duplex brakes are used, and semielliptic springs attend to the suspension.

The 20-seater bus body to be shown is by the exhibitors, and the finish la of a high-class order.

GARNER. Stand 119.

Henry Garner, Ltd., Moseley Works, Birmingham.

GOODS-CARRYING vehicles take preference in the Garner range, as typified by their exhibits. A 2-21--ton chassis designated A.E. has a load capacity of 2 tons 18 cwt., including body. David Brown overhead worm drive is incorporated in the Kirkstall one-piece forged rear axle ; engine and gearbox suspension is of the thiee-point type, and a semi-forward driving position is employed on this model.

Mounted on one of these chassis will be a municipal refuse tipping body ; this model is the same as described above, but has a shorter wheelbase and solid tyres. The driver's cab is of the all-weather variety, and the tipping gear is hand operated by a telescopic screw.

Another A.E. chassis will be shown equipped with a general-purpose tipping body and detachable street water tank and sprinklers; this also has a short wheelbase, namely, 11 ft., and a similar driver's cab to the foregoing exhibit. The detachable 440-gallon circular street watering tank with anti-splash baffle plates, is included, together with two sPecial rear gravity sprinkler heads with an adjustable feed and a spread variable up to 24 ft.

Pull forward driving position is given on the A.E.O. chassis, which will be shown with a tilt van body having patent hinged side wings giving full accessibility to the engine on each side.

To conform with modern practice in passenger work there is the L.P. type low-loading chassis carrying a 26seater bus body; this also has the three-point engine suspension, and four-wheel brakes operated by foot, the hand. lever operating shoes on the rear wheels only. Fuel feed is by Autovac, and the tyre equipment is of the giant cord pneumatic variety. The coachwork consists of a 26seater side-entrance saloon-type single-deck bus body, the door being towards the rear ; all the seats are upholstered with loose cushions. This model complies throughout with the Ministry of Transport's regulations.

GARRETT. Stand 106 Richard Garrett apd Sons, Ltd., Aldwych House, • Aldwych, London, W.C.2.

TROLLEY-BUSES, electric-battery vehicles, undertype steam wagons and steel trailers comprise a few of the products of this enterprising concern which will be seen by the public when Olympia's doors open. The trolley-bus was described at considerable length in recent issues of The Colnntercial Motor. This is fitted with a 10-speed-forward-andreverse gear, with a special device enabling thc controller to return to the " oif " position so soon as the pedal is released. This is similar in principle to the "dead man's" handle in use on the Underground railways. The motor is a 50 h.p. Bull ; the rear-wheel brakes are operated on the Westinghouse principle, and front-wheel brakes are included in the speeification. The body on the vehicle to be exhibited will be a 36-seater single-decker bus.

Possessed of a long-standing reputation is the 2-ton battery vehicle, which also has a Bull motor and a special control system, in which brake operation returns the controller to the neutral position. This exhibit will be fitted with a Garrett patent auxiliary controlling gear for steering the vehicle from the pavement.

The latest improved undertype steam wagon will also be on the stand. This is designed to take loads up to 8 tons, and is fitted with roller bearings throughout and a change. speed gear. The rear axle is dead and the drive is balanced. The steam control valve is foot-operated and the boiler is fired from the bottom, -with accessibility for cleaning and expanding the tubes when necessary. The body fitted will be of the platform type.

The turntable type steel trailer to be exhibited is mounted on Timken adjustable roller bearings and has pressed-steel wheels and solid tyres. The drawbar is of the spring variety and the platfrom body has hinged sides and tailboard.

The trolley-bus is a comparatively recent addition to the Garrett programme, but it has already found favour and its performance is meritorious. The Bull motors used are made by the associated company of the vehicle manufacturers.

G.M.C. AND CHEVROLET. Stand 112 General Motors, Ltd.. Edgware Road, The Hyde, Hendon, London, N.W.9.

OMBINED, these two makes of commercial vehicles will _e be represented by no fewer than 11 exhibits, two of them being of G.M.C. manufacture and the remainder Chevrolets. Both G.M.C.'s will be exhibited in chassis D22 form, the K32 model being of 2-ton capacity and the K17 of 30-cwt. capacity. Features of the G.M.C. engine are detachable cylinder sleeves, forced-feed lubrication, heated induction manifold, detachable engine bearer arms and tappet assemblies constructed in groups of four bolted to the side of the ,cylinder block casting. Dealing with the Chevrolet models, two capacities will be exhibited, the 1-tonner and the 10-cwt. On the larger model will be shown four different types of body, the fifth exhibit being a bare chassis. In the ease of the 10-cwtvariety one chassis and three vehicles carrying bodies will be on view. The 10-cwt. chassis has a four-cylinder overhead-valve engine, the cylinders being cast in one with the upper half of the crankcase. A single dry-plate clutch carries the power to the three-speed gearbox, from which it travels to the banjo-type pressed-steel rear axle, having a spiral bevel gear set. The hand brake operates an internal expanding set of shoes, whereas the foot brake contracts bands on the outside of the 11-in, drums. Central control is provided, and worm-and-wheel steering is a standard equipment. A rural bus and a traveller's brougham with coachwork by Spurling, Ltd., will form two of the exhibits, and a van body of Chevrolet manufacture will figure on the third complete exhibit of this size. Coming to the 1-tonner, this also has an overhead fourcylinder engine and the design is, generally speaking.

similar to that of the smaller chassis, but of course, the frame is considerably more substantial to 'withstand the added loads. Pressure grease-gun lubrication is standardized on both chassis. London Lorries, Ltd., are building the boxvau and bus coachwork and Spnrling, Ltd., the char-a-banes body, but the drop-sided lorry body will be of the Chevrolet menufact are.

GUY. Stand 99 Guy Motors, Ltd., Fallings Park, Wolverhampton.

SIX vehicles will oe arranged under the mune of Guy, these ranging from a 1-tonner up to low-level buses of 32-seater capacity. The 1-tonner has an 18 h.p. engine with four cylinders, 85 mm. bo.!e. and 120 mm. stroke, the chassis weight being 22 cwt. Pneumatic tyres are fitted, single at the front and twin at the rear, all interchangeable, and front-wheel brakes are supplied as optional equipment.

The 30-cwt. Guy boxvan has a 22 h.p. engine; the cylinder bore of this is 3 mm. greater than that of the 1-ton chassis. The front tyres are pneumatics and at the rear are twin solids. Next in order of power is the 26 h.p. 20-seater oneman bus, which has a four-cylinder engine, with a 4-in, bore and a 5i-im stroke, the chassis weight being 2 tons ; this model has a 10-in ground clearance. Single front and twin rear pneumatic tyres are used.

In view of the marked passenger nature which the Show will have, the 30 h.p. speed model 20-seater coach is particularly interesting. This has a six-cylinder engine with a mm. bore and 130 mm. stroke. Brakes are provided on all four wheels and in the transmission system, and 895 mm. by 135 mm. tyres are used. One of the outstanding vehicles which will be shown by the GuY Co. is the low-load him bus chassis, having a fourcylinder engine of 4t ins, bore and 54 ins. stroke. The vehicle is suitable for carrying single-deck bodies of 26-32-seater capacity. The low-loading level is obtained by means of a special frame dropped considerably behind the dash and to the rear of the back axle. Tinderslung, rear springs are employed,. these being clamped to substantial brackets beneath the .axle. The special Guy engine and gearbox mounting is, of course, employed. Four-Wheel brakes Vill be fitted to the model to he exhibited.

Efficient lubrication of the rear springs is provided by means of a system of oil passages from the rear axle through the spring anchorages—thus the oil permeates through the leaves. As in the case of other Guy products, the question of accessibility has received a great deal of attention, and the big-ends, valve gear, cylinder heads, and so forth, are quickly dealt with without the necessity for dismantling many parts.

On the same •chassis will be shown -a low-level bus, the details being as in the case of the stripped chassis, except that the wheelbase is 1 ft. 2 ins. longer. The body houses

30-32 passengers • Other Guy vehicles will be fauna on various coachbuilders' stands. one being a 2-tonner, two buses, one a 30-seater, and a 3-ton lsrry,

G.V. Stand 70

General Vehicle Co., Ltd., 43, Shoe Lane, London, E.C. 4.

PECI3LIAR in that this will be the only all-electric cornmercied vehicle stand in the Exhibition, the G.V. products will undoubtedly attract their full share of attention. The 2-4-ton electric road tractor will be exhibited equipped with U.V.-Phileci batteries. This vehicle is to be shown in con

junction with a specially designed two-wheel trailer for the collection of offensive reffise, the body being designed on sanitary fines, lined with sheet metal throughout and having a low load-line, i.e., just over 2 ft. Another 2-ton type to be shown has a boxvan body specially designed for carriers for parcel work, a feature being the easy accessibility to the interior of the body through the driver's cab, thus enabling delivery work to be carried out entirely by one man.

The all-wood steel-lined end-tipping body will be exhibited fitted to a 3i-ton electric chassis, fitted with an Edwards hydraulic tipping gear, electrically operated. Still larger is

a 5-ton standard ehassis, which will be exhibited with a flat platform body and standard cab, designed for the transport of long ladders and general merchandise.

A -2-ton Baker Hy-lift industrial vehicle truck with twowheel 'drive and four-wheel steering is to be displayed. This model has a platform lift of 72 ins. The lifting gear is of the twin-cable hoist type with an automatic limit stop at each end of the travel. The vehicle is especially useful for' warehouse work. The 3-ton truck is similar, but has a hightorque compound motor for lifting the load ; the platform raising limit is 15A ins., and this is reached in 10 secs.. Finally, there will be on view an electric tractor of the Baker 10-ton type. This is a massive vehicle, supplied for extremely heavy duty on various gauges of rail or for road purposes. It can do 4 mph. with a full load and is very useful for hauling trailer trains.

HALLEY. Stand 97 Halley's Industrial Motors, Ltd., Yoker, Glasgow.

SEVEN exhibits OM be found on the stand of this wellknown company, who have, constructed commercial motor vehicles for many years. The first of these is the 30-cwt. chassis for the Subsidy-type Plight lorry. The four-cylinder engine has a monobloc casting, in which the top half of the crankcase is included. The head is detachable and the camshaft and valve tappets are very accessible through a large inspection door.

Lubrication is by pressure pump to the main bearings, whilst the big-ends are lubricated by dippers from troughs placed in the bottom of the sump immediately below the connecting rod and fed by pump. A three-piece radiator is pro

• vid•ed, also a circulating pump fitted in the front of the cylinder casting and forming a combined unit -with an aluminium fan. Three-point suspension is used for the engine, clutch and gearbox unit, thus preventing harmful effects through chassis distortion. Fabric uniVersal joints are provided, these conveying the power to the Overhead worth-driven rear axle.

A larger type is the 2-ton chassis, having a 20-40 h.p. engine of the four-cylinder type of a similar design to that fitted to the 30-cwt. vehicle.

Three passenger vehicles will be exhibited, special attention having been given to springing, braking and petrol consumption to ensure efficient opeeation. Smart appearance is given by the streamline radiator and bonnet, and ample equipment is specified.

Known as the Talisman is a passenger chassis of 14-ft. Wheelbase, equipped with a four-cylinder engine capable of developing 40 b.h.p. Unit construction is employed, engine, plate, clutch and four-speed gearbox being three-paint suspended in the frame. A handsome 20-seater bus body will ho shown on this chassis.

The next will be the Ivanhoe, carrying e char-e-bancs body specially designed ft.r this chassis. The wheelbase is longer than that of the Talisman and the seating arrangement gives the maximum of comfort to passengers. A sixcylinder engine is used, and this should provide exceptionally. smooth running. A single-plate Halley clutch is employed in conjunction with a four-speed gearbox and worm-driven rear axle.

Fifth on the list will he the Kenilworth, intended for a bus body-and suitable for carrying 32 passengers. The 4-in. by 6-in. six-cylinder engine again has a single-plate clutch and fourspeed gearbox; three-point suspended.

A standard 4-ton commercial chassis will be exhibited fitted with a 1,000-gallou triple-compartment petrol tank and the well-known Halley six-cylinder engine. JOWETT. Stand 15 Jowett Cars, Ltd., Bradford Road, Idle, Bradford.

SINCE 1910 minor changes only have been made in the design of Jowett cars and commercial vehicles, which speaks well for their reliability and solidity. Two types of chassis will be exhibited—those with long and short wheelbases—which are suitable for various purposes and give the purchaser a choice of body size. In both cases the engine is of the two-cylinder horizontally opposed type with sideby-side valves and pressure-feed lubrication. Coil ignition, Zenith carburetter and thermo-siphonie cooling are included. The induction system is water-heated throughout and the lighting system is of special design, having a dynamo output controllable by the driver.

On the short-wheelbase chassis will be exhibited a light ran body, having ash framework covered with three-ply material. Also on the long chassis will be shown a light van of larger dimensions, and the third exhibit will be a pareelear having seating accommodation for two people. The rear of the chassis is occupied by a large box compartment with two doors opening outwards. This is to be shown on the short wheelbase chassis, but, as a matter of fact, it can be fitted to either. • Braking on all models is by external-contracting bands on the transmission and rear wheels. Accessibility is a marked feature of the chassis, and this should appeal with considerable force to those who have to attend to mechanical maintenance in addition to other business duties.

HARRIER. Stand SS Harrier Motors, Ltd., Harrier Works, Huddersfield.

pROGRESS has always been one of the marked features of the Karrier programme, and visitors to the Show wit], we are certain, in no wise be disappointed in this year's exhibits. The six-cylinder, six-wheel saloon bus will be one of the most attractive of the exhibits, and is certain to draw a large crowd in view of its original design.

The 22-40 h.p. Z-type chassis carries a gross load of 33 cwt. This has a final drive by overhead worm, four-speed ball-bearing gearbox, and a governed engine. Model Z has a 20-36 h.p. engine and carries a 14-seater Devon motor coach body. Detachable steel-disc wheels, with pneumatic tyres, are provided, the transmission being similar to the foregoing exhibit, with the exception that a cone clutch is fitted instead of one of the single-plate type.

• A new low-loading-line single-decker bus is to be exhibited is the CL type with a Norfolk-pattern body. The frame is an interesting production, the springs being underslung and the worm gear inverted.

Still larger is the 50-60 h.p. K.L. model, which will be shown fitted with a 39-seater single-deck bus body, known as the Stafford. Again a law-load-line frame is employed, with the same springing and transmission layout. Electric lighting is used on this model.

Coming to the goods vehicles, there will be the 30-48 h.p. CL chassis with hydraulically operated tipping body con tracted in steel. The low-load-fine frame will again be noticeable. Oil lamps are standardised on this exhibit.

An oil fuel tank of 1,200 gallons capacity will be borne by a K5 chassis, having a 50-60 h.p. engine. A type Jil chassis will carry dual-purpose tank wagon with a 32-45 h.p. engine.

Last, but by no means least, there will be the six-cylinder six-wheel saloon coach, the chassis weight of which is only 3 tons. The brakes are power operated, and the frame is of

the low-load-line variety. The engine develops 00 h.p. at 1,200 r.p.m.; a four-speed gearbox and twin rear axles are provided. In additionto the Westinghouse brakes operated D24

on the four driving wheels, there is a transmission brake, which is operated by pedal behind the gearbox. The floor level is but 20 ins, from the ground. Particular items of interest are the "spectacle frame" rear axle, springing layout, and the cross-over driver by silent chain.

LANCIA. Stand 91.

Curtis Automobile Co., Ltd., Curtis Buildings, Abbey Road, Park Royal, N.W.10.

Otype of chassis only will be shown on the Lancia and, namely, the familiar Pentaiota. Five examples will be exhibited, one being a chassis, the other four comprising two coaches, One bus and one saloon. Details of the chassis are well known, amongst other items being an electric lighting and starting set of the Lancia-Rushmore construction with two bead, two auxiliary, one dash and one tail lamps. The chassis is robustly constructed throughout, being designed to withstand the arduous conditions, particularly those encountered in Italy, from which country it emanates. Particularly does this apply to the front-wheel-braking system and front axle. The latter is ribbed to withstand the severe stresses imposed by heavy braking on steep descents. Single pneumatic tyres are fitted at the front and twins at the rear.

Mounted on the chassis previously described there is to be a 23,25-seater Perfection low-loading open coach body with coachwork by Hall, Lewis and Co., Ltd. Jackson type hood fittings are employed, whilst the all-weather side curtains are of the rigid type, and the upholstery is in antique leather and the windscreen is V-shaped, with double de Electors.

An I8-19-seater with standard all-weather coach body by London Lorries, Ltd., will be another exhibit incorporating Beatonson headwork, with large plate-glass drop windows, staircase front-entrance door, an offside door for the driver, and an emergency door. Semi-bucket seats are employed, and the finish is of a very high-class nature.

The 26-seater service omnibus has a body by Messrs. Strachein and Brown and incorporates in its design a mechanically operated front-entrance door, partition behind the driver, centre gangway, rear emergency door and springback seats. The windows are of the Rtrachati drop type, and Airvae roof ventilators are provided.

LA}' kLY. Stand 67

Lally (England) Co., Ltd., 20-26, Lonsdale Road, London, N.W.6.

MUNICIPAL vehicles, six in number, will be displayed on the Laffly stand and variety will prove one of the attractions of the programme. A road-sweeping machine, a combined watering, washing and sweeping outfit, a gully emptier, a road roller, a portable fire-engine, and a vacuum cleaner will. comprise the array, 60 for as the public-utility type of machine is concerned. In addition to these there will be one of the new model 2i-tonners designed for high-speed work either in connection with goods or passenger transport.

The road sweeper is a four-wheel vehicle carrying a broom at an angle of 30 degrees to the line of travel. Power is transmitted from the main gearbox by chain. In order to lay the dust a spraying tube is 'fitted along the whole length, of the broom, and the pressure of the rotating brush upon the road can be varied, independent of the weight of the vehicle.

The combined watering, washing and sweeping outfit has high-pressure flushing 'jets, which are controllable for quantity, and the spraying range can be varied from 10 ft. to 60 ft.

The gully emptier consists of a chassis carrying a suction pump, a double-compartment cylindrical tank and two water ing boxes. The four-cylinder -engine develops 35 h.p. at 1,200 r.p.m. The gearbox is of cast-steel and provides four speeds and reverse.' The tank holds 1,100 gallons.

An attraction to many will no doubt be the 2i-ton or 26seater chassis, which is an entirely new model for 1926. This has a four-cylinder engine, with a bore of 90 mm. and a stroke of 130 rum., the inlet valves being situated overhead. There is a disc clutch and four-speed gearbox leading to a spiralbevel drive, which has a top-gear ratio of 61 to 1. For such a speedy chassis adequate braking is required. This has been attended to by pedal-operated four-wheel brakes, the hand lever operating a separate pair of shoes' in the rear wheels. Some 45 m.p.h. are claimed on top gear.

LATIL. Stand 103 L. C. Rawfence and Co., Ltd., 39, Sackville Street, London, w.f.

WITH the exception of the four-wheel-drive tractor, all the chassis on this stand will be of the low loading-line description. Dealing with the 30-cwt. variety first, one of these will be shown complete with a standard body, priced at £525. , The four-cylinder side-by-side-valve engine has pressure-pump lubrication, a &lex carburetter, pump cooling, single-plate dutch and four-speed gearbox. The foot brake acts upon a drum on the cardan shaft and the hand lever operates the shoes working in the rear-wheel drums. Electric lighting and starting equipment are fitted to the model in question. Mounted on a similar chassis will be the low-loading box van and coach.

Type B2, which carries a load of 2-2i tons, will be shown in chassis form. This has an engine of similar dimensions to the model previously described, but the foot brake takes effect on the front wheels and card= shaft, the hand brake acting on the rear wheels.

Those who are interested in the transport of horses should not miss seeing the type V.L.3 Lath l 2-3-tonner to be ex hibited and which will have a body for the safe transport of two horses and attendants. A cone clutch is fitted.

The final exhibit will be a four-wheel-drive tractor known as type T.L. This has a governed engine speed of 1,200 r.p.m. and a, six-speed gearbox, three being for use in the field and three on the road. In addition, of course, there is a reverse gear. Steering takes effect on a11 four wheels and the braking also acts at four points.

LEYLAND. Stand 104 Leyland Motors, Ltd., Leyland, Lancs.

ONE of the most famous names in the road transport industry is that of Leyland. Special interest will be shown in the company's exhibits this year in view of the fact that three. new models, which are of the latest school of design and all intended for passenger purposes will be on view. Features of the new, models are a low load-line, four-wheel brakes, lightest possible chassis consistent with the necessary strength for safety and possible overload, pneumatic tyres, overhead-valve power units with the cylinders cast in pairs and having detachable -heads, vertical carburetters with "hot spets " in the induction branch and threepoint engine suspension.

Known as the Lioness is a bonneted type of cha_ssis, and this will be exhibited fitted with a 26-seater single-deck bus body, laid out for one-man operation. The clutch is of the single-plate fabric-to-metal type and the gearbox is controlled by the driver's right hand.

A larger model is the Lion, which is a side-type low-loading chassis, and will be exhibited as a 31-seater bus of the singledeck pattern. On this type of vehicle the rear axle is of the double-reduction variety, whereas the overhead worm type is fitted to the Lioness. Servo operation is employed for the front-wheel brakes when these are fitted ; they rank as an additional item to the standard specification.

The largest of the three new chassis is the Leviathan, and it will be on view in the form of a 52-seater double-decker bus This model has a cone clutch and double-reduction axle, the first reduction being through spiral bevel sears and the second through double helical gears. Rear-wed and traissmission brakes are standard, the former, being internalexpanding. and the latter external-contracting.

The QII2 chassis is a 6-tanner of the bonneted type, and at the Show an example will form the basis of a porcelainlined 1,300-gallon tank wagon built for milk transport. The familiar Leyland axle is fitted, this being one of the wellknown models as made in previous years.

The small Trojan van on the company's stand wilt attract the attention of those dealing with light loads. Its capacity is 7 ewt. and it is propelled by a two-stroke engine having four cylinders coupled in pairs, with a mechanical starter situated to the right of the driver. Two-speed epicyclic gearing is provided, and the layout is highly satisfactory, but essentially simple. Driving may be said to be foolproof.

LONGFRAME. Stand 51 Longframe Six-wheeler Construction Co., 58, Bredgade, Copenhagen.

LAST exhibited, in 1923, the Longframe construction principle has made great progress with regard to its field of activity.

An innovation for this year's Show will be the introduction of the standard type of Longframe vehicle to the British market. This construction has been exploited not only in connection with the manufacture of six-wheeled vehicles, but also for the conversion of existing four-wheeled chassis to the larger type. Such Longframe conversions and standard types will be. exhibited attached to two Chevrolet chassis. One of these vehicles will have a 19-seater Durham omnibus body built by London Lorries, Ltd., and the othor Chevrolet six-wheeler will be shown as a dropped-sided lorry with body by Spurling Motor Bodies, Ltd. The four-wheel chassis, when converted into a six-wheeler, pulls, but does not carry, the additional load. The extension, therefore, in contrast with other extended frameS, and Wording to the claims of the concern, does not result in overloading the chassis or the driving axle, and does not increase the maximum stresses on the transmission.

On the standard Chevrolet-Longframe the rear wheels are, of course, at all times parallel to the chassis, whereas on the larger models the wheels at the extreme rear end of the vehicle also steer, in addition to the front wheels.

M. and D. . Stand 80 The Rhode Motor Co., Elytheswood Road, Tyseley, Birmingham.

THE 20-25-c*t. commercial vehicle known as the M. and D. is one of the few which employ an overhead-camshaft engine; this is operated by spiral bevels, the cylinder head is detachable and the barrel is cast monobloc with the upper half of the crankcase. Large water spaces are provided, and the induction manifold is water jacketed; three large whitemetal bearings are provided for the crankshaft, which is fully balanced, and the pistons are of aluminium and connecting rods of Duralumin—exampres of the most up-to-date practice. A single-plate steel clutch, running in oil, is used, and it transmits the power to a four-speed gearbox, which is centrally located. The gear ratios are optional, either 7.66 to 1 or 6.25 to 1 on top gear. The speedometer is driven from the rear of the gearbox. The final drive is by overhead worm by David Brown and Sons, a cast-steel axle and worm case being employed. The front axle has been specially strengthened to withstand the stresses caused by the Alford and Alder front-wheel brakes which are fitted. Worm-and-wheel steering is standardized. Semi-elliptic springs are fitted all round. Chassis lubrication is by grease gun throughout.

Flexibility in engine mounting is • ensured by rubber cushions interposed between the engine bearer arms at the forward end and the blackets. The rear of the gearbox is suspended from a frame cross-member, which also houses the ball at the front end of the torque tube. MANN. Stand 125 Mann's Patent Steam Cart and Wagon Co., Ltd., Pepper Road Works, Hunslet, Leeds.

AT the Exhibition an Express unclertype wagon of Mann manufacture, fitted with a fled body, will be shown,. also a number of assembly units, such as the rear axle and crankshaft. In this wagon a vertical boiler is fitted in the driver's cab and the engine is located horizontally underneath the chassis. By removing a big inspection door the whole engine motion work is fully accessible without getting under the wagon frame. The engine is of the poppet-valve type, and the valves are accessible, clue to the method of mounting the engine ; it is carried at three points so as to be unaffected by auy twisting or bending of the frame.

Transmission is by a propeller shaft to a cased-in back axle of the full-floating typ3, so that the driving shafts transmit torsion only, the weight being taken by the outer casing. The main brake is steam operated direct on the back wheels. with an automatic controllable reducing valve, giving sweet action and great power. • The second brake is on a drum on the propeller shaft and is easily adjustable. From the driver's seat an unusually good view is obtained of the road ahead as a result of placing the driver well to the right of the boiler and chimney. All controls are accessible,. and the makers have long claimed that their design gives perfect one-man control. Ackerman steering is standardized, the worm and wheel being located to the right MeCURD. Stand 79 The McCurd Lorry Manufacturing Co., Ltd., Hayes, Middlesex.

TWPmodes will be shown on this stand, the familiar 4-tanner, which has varied but little in the past ten years, and an entirely new model 2-tonner of the latest design. Taking the older type of chassis first, this has an engine three-point suspended in the frame and a five-bearing crankshaft with forced-feed lubrication. The cylinders are of the T-headed pattern, the valve' -J being operated by two camshafts. The gearbox likewise has three-point suspension and the rear axle is of the" full-floating type. Grease-gun lubrication is naturally standardized, as it is on the smaller model.

Designed to gig trouble-free service and long life, the McCurd 2-tonner shows evidence of close attention to the problem of accessibility. The .oil pestles through two filters before being pumped to the engine ; both these can be removed for cleaning in a few moments. Lightness of reciprocating parts has been achieved. Ground gears are employed in the gearbox, and a specialelocking device is fitted to prevent engagement of two gears simultaneously. A solid-steel forged axle of the full-floating type is provided, no torque or driving strains being taken threugh the springs.

Ball-thrust meal are employed in the steering heads in• grease-tight housing, and ball-thrust races are employed ip the steering, which should ensure light and easy control. Pour-wheel brakes are standardized, in addition to a transmission brake drmn behind the gearbox.

A po'nt of note is the clutch design, which incorporates a grease lubrication system avoiding the necessity for constant attention.

MODERN WHEEL DRIVE (S.L.M.). Stand 126 Swiss Locomotive and Machine Works, care of Modern Wheel Drive, Ltd., 17, Victoria Street, London, S.W. 1. ORIGINALITY in mechanical design will be observable on this stand. Two of the most remarkable features of this type of vehicle are the very low frame and the 'position of the front axle, which is practically below the dashboard. These constructional details, together with the unique type of gearbox, are claimed to e great advances in motor vehicle construction. The usual back-axle drive has been entirely de

p2.8 parted from, and the power is transmitted to the front wheels 'only.

With the removal of all mechanism from the rear axle the whole of the space behind the driver's seat is free of moving parts and, consequently, there is much more scope for the body constructor to meet the varying requirements of his customers. Prout-wheel drive has many substantial advan tages in that it will overcome obstacles on the road more easily than a vehicle which is pushed, that is, one having rear-wheel drive, and the skidding danger is considerably reduced. The whole of the motor and transmission unit can be removed without interfering with the body, and, as these units are interchangeable, continuity of service is largely guaranteed.

The 2-tonner, with a special low body, has a front lifeguard in the form of a pivoted fence with a release gear. The 3-4-ton chassis also, of course, has front-wheel drive and employs the special type of oil-cuierated clutch peculiar to this vehicle ; this will be shown in chassis form. Visitors to the Show should not miss the special gearbox, which is being demonstrated as a separate unit in order to facilitate the inspection of the mechanical principles involved.

• SCAMMELL. Stand 108 ScammellLorries, Ltd., 14, Holborn, London, E.C.1.

FAMOUS for their six-wheeled tractor-trailers, the makers of the Scammell range of commercial models will no doubt attract even larger crowds than those which normally collect to view their products, by reason of the exhibit of the Scammell Antovan. Prominent on the stand will be a 3,300-gallon fuel-oil tank wagon for Shell Mex, Ltd: This is of the special frameless type, the machine weighing only 6 tons 15 cwt„ although its useful carrying capacity is over 12 tons. A Scammel-built three-cylinder radial air compressor, by which the whole load of 12 tons can be discharged in, some 15 minutes, is fitted.

There will also be shown the carrier only of a 2,500gallon petrol tank wagon, this having elliptical tanks, subdivided into five compartments to meet the English regn lations for the transport of petroleum spirit. Another interesting exhibit will be the 12-ton drop-frame cable carrier, with winch and loading ramp ; this machine will have pneumatic tyres on the front wheels and is intended for service in the Persian oil e fields.

A Vehicle which will attract much attention is the 12-ton flat-platform brewer's lorry. All the six-wheelers embody the Scammell principles of constructiOn ; the motive unit has a double springing system, by which all the weight of the carrier is taken: on the driving axle through separate springs, the flexible springs supporting the motive unit working always under constant load, unaffected by the weight on the carrier.

Intended for short-distance haulage in towns is the Scammell Atitovan, having a 2i-tort load capacity ; the lay1528

out is original, in that front-wheel drive is employed,-the engine and gearbox and transmission mechanism forming a compact unit, driving each front wheel direct by a universally jointed shaft. A low-loading-line and very small back wheels are employed, whilst, for general use, large back wheels and a high frame can be fitted, without altering the machinery and driving mechanism. A three-cylilticler-radial engine is used, having a vertical crankshaft and a starting handle on top of the engine. This exhibit will draw a considerable crowd. It was described exclusively in our issue of last week.

SENTINEL. Stand 36 Sentinel Waggon Works, Ltd., Shrewsbury.

AFEATURE of the exhibits to be staged by the Sentinel Co. will be the large number of vehicles which are repeat orders by well-known transport users. For instance, there will be a 6-toriner with a flat-platform body to the order of J. Lyons and Co., Ltd.; a 17-ft. 6-tonner with millers' tilt-van body for Hovis, Ltd., and a 6-ton flat-platform wagon fitted with a permanent canopy and tailboard for the Express Dairy Co. In addition, thorn will be a three-way tipping wagon, and a specially shortened tipper ordered by the Gas Light and Coke Co.

So far as design is concerned, the main features remain unchanged since 1D23; improvements‘ in details as suggested by experience have, of course, been carried out, amongst which may be mentioned the brake hand-wheel, which has been considerably increased in size, thus giving more power to the operator. The pipes between the pump and the feedwater heater, also those from the feed-water heater to the boiler, have been increased in diameter to allow of a more ready flow; the original funnel base has been considerably altered, and the damper has been removed thereform and placed at the top of the funnel. The last-named component has also been' entirely modified, its lining being shaped as venturi tube.

• An important modification is the conversion of the lighting dynamo drive from belt to chain, which is thus less likely to become deranged by adverse weather conditions and will give a steadier output from the instrument. Readers will recall that the Sentinel is an undertvpe wagon mounted on semi-elliptic springs all round, with chain drive and a vertical boiler. Ackerman steering is used, and the driver's cab is amply, propnrtioned to give the maximum comfort to its occupants.

SPA. Stand 69 Spa Motors, 244, Earl's Court Road, London, S.W.5.

-0 ITILT in Italy the Spa vehicles, of which several will _IU) be shown, always attract attention by reason of their clean design and robust. appearance. The specification of models 250/B and 25C/A remain the same for 1926, but the Model T differs in the following respects. The wheelbase is 15 ft. and the load capacity 3 tons 10 cwt. The standard type of cross head-pin universal joint is replaced by three Hardy flexible joints, and braking is effected on all four wheels by means of II pedal-operated system incorporating a servo motor, the hand lever applying the rearwheel brakes. only. A. new model, known as T31, will be available, and this has the same engine, but differing in other respects.

The engines employed are of the four-cylinder type with detachable heads and three-bearing crankshafts. The drive is by means of bevels and double-reduction gear, the differen

tial gear having four star pinions. The Italian characteristic of clean design is maniLst in the torque tube and axle assembly, the engine layout also being free from -excrescences.

• STAR. Stand 98 The Star Engineering Co., Ltd., Star Motor Works, Frederick Street, WolverhaVon.

IN 1898 the Star Engineering Co., Ltd., were manufacturling motor vehic'es, and it is only to be expected that visitors to Olympia will be interested in the precincts of such an old-established company. Five exhibits will be shown-four complete vehicles and one chassis—of four distinct types.

The first is to be a 25-cwt. chassis with van body. The engine hag a detachable Lead and side-by-side valves, the gearbox being mounted as a unit with the engine. A single dry-plate clut.di, which is carried on the first-motion shaft cf the gearbox is employed. A station bus body will be shown on this chassis, the tyres being larger than those on the van tadel.

A feature of the 25-owl. chassis is the relatively large engine employed for the weight of vehicle; the high power to weight ratio thus provided should give good performance coupled with economical running. The four-speed gearbox, fabric universal joints and all-steel material indicate the most modern school of design.

A similar engine is used in the 2-ton model, which will be shown in chassis form mounted on Solid tyres. This is a well-known and popular vehicle and can be obtained with four-wheel braking if desired. The chassis exhibited will have solid tyres but pneumatics are obtainable.

The largest vehicle in the Sfar programme for 1926 is a 50-60-cwt. chassic, an example of which will be shown with a van body. A full-floating axle, incorporating torque and radius rods, is ,:mployed. The baby on this stand will be a 15-cwt. delivery van, having a 20 h.p. engine ofthe same dimensions as that fitted to the 25-cwt. machine. Steelspoke wheels and pneumatic tyres will be fitted on this exhibit.

THE 6-ton, chain-driven steam tipping wagon is the model selected by the Yorkshire Co. for exhibition. This is not a new vehicle, but one which has given a satisfactory account

of itself in service for many years. The engine of this vehicle is self-contained in one casing, which ensures an efficient state of lubrication, and is of the balanced vertical combined side-valve type, the cylinders being at the back of the driver. The boiler is of the fire-tube type, and has an ample effective heating surface. Gearing is of cast-steel, machine-cut throughout, and the final drive to the Compensating gear is transmitted through a steel roller chain.

Braking is effected by two independent sets, one acting direct on the driving wheels ; the other is a band brake, which is pedal-operated. The special Yorkshire tipping gear is engine-operated. The body is supported almost throughout its entire length upon the chassis frame, but when in the tipping position it runs back until its centre is approiimatoly over the end point of the wagon frame, thus adding to the tipping action and reducing the amount of energy which has to be given off by the tipping gear. The tipping angle is higher, it is claimed, than that of any other type.
