BRITISH VEHICLES AT OLYMPIA.

Brief Descriptions of the Exhibits to be Shown to the Public on Friday, with the Essential Details of all Chassis Being Constructed.

N THE DESCRIPTIONS which follow, we deal with commercial motor vehicles which fall into the category of British made. We have eaadeav-. oured, in respect of each make to give a list of the various types of chassis manufactured with the feiv details of each which we consider would be essential in the 'choice of a. vehicle, namely, its capacity in *eight of goods or number of passengers, the plat,-. form space available (and throughout we have given the space from the rear of the dashboard, thus including the space which must be given upto the driver's seat and cab. Where this practice is departed from, as in the case of van chassis, a note is made of the fact), tht type and size of tyres and the price. In nearly every case the price for the chassis complete with tyres, and that is understood throughout, The Albion exhibit will be thoroughly comprehensive.. There will be two examples of the .32 h.p. chassis, which will be shown as a31ton tipping wagon and as a 4 tonner. The tipping wagon is a type that has been • standardized with great success by the Albion Co„ the tipping gear consisting of a Hele-Shaw pump and a hydraulic ram capable of raising and Towering the body in about

14 min. and min. respectively. This model is, of course, chain driven, and the four-cylinder engine is of the monobloc type, embodying the Various AlbionMurray. patents relating to lubrication, governing, magneto dna% combination of fan and pump, and single-disc clutch.

The popular 30 cwt. model will be shown with a van body. This has, a 20 h.p.. engine, which has its cylinders in pairs, and the Murray mechanical lubricator, in-this ease,. is replaced by a pump driven of the crankshaft. A live axle is used in this model, the final drive being by bevel. the exceptions being indicated. Frequently the price -given is that for the complete vehicle, in which case the fact is stated. We have not given the horse-power, the type of carburetter, ignition, number of gears, final drive, wheels, etc., as nowa,days the specification of a. given chassis of well-known make is not capable of being varied to suit whims and fancies. The makers have laid down specifications on which they are prepared that their vehicles shall stand fall, and the buyer, therefore does not choose his purchase because it --has a certain make of carburetter or because the clutch is of the plate type and not a leather-faced cone ; he chooses on the maker's reputation and on the suitability of the machine for his class of work. The details we provide ar, therefore, we hope, all sufficient.

with a steel-end-tipping body with tailboard hinged at the top and single ram hydraulic tipping. gear with the ram

positioned between the body and the driver's cab, the hydraulic pump being

driven from the gearbox layshaft; -a 3 ton Y.J. type passenger chassis with a char-l-basics de luxe body upholstered i-.{1 leather, with .seatiffg accommodation. fel

28 passengers, and provided witha table round which the seats are positioned.

This machine is of particular interest, as it will be provided with Michelin steel disc wheels and pneumatic tyres, single, at the front and twin at the mar. • The other two exhibits will no doubt, also create considerable interest. One is

K.typ-e chassis carrying a saloon omnihue -body with a passenger capacity of

32. This machine also will have.Miche lin steel disc wheels and pneumatic tyres. The second K-type chassis will be shown with a lorry body,provided with hinged detachable sides; this vehicle, of course, will be shod with solid tyres.

All the vehicles exhibited will be provided with engines of the company's own manufacture, that on the K type lacing of 30 h.pl and those of the two Y type. chassis of 45 h.p.

' The Y type chasSis has an external ,cone clutch, four-Speed spur type gear. , box, and overhead worm final drive, while the K type has a multiple dry-disc -clutch, three-speed silent chain type gearbox, and underneath worm drive.

The whole of the exhibits are fitted with dynamo lighting, and. are exceptionally well finished.

For further particulars of both models we would refer our readers to an article which appears elsewhere in this issue. Amongst the steam exhibits at the -Show a considerabhi. amount of interest is certain to centre on the new Atkinson steamer. Only one vehicle will be shown, but this will incorporate the new Uniflow engine, which is the only engine of its type fitted to a commercial vehicle, and a powerful footbrake of the internal expanding type operating on drums bolted to the rear wheels. The Atkinson engine has two cylinders of the doubleacang simple type, in which the inlet valves consist of hardened steel halls operated by push rods from a camshaft enclosed within the casing and running in oil, The exhaust for each side of the piston is taken through a port situated about the middle of the cylinder, so that the direction of the flow of steam is not

altered. The boiler is of the vertical type, and is lagged with woven asbestos cased with aluminium sheeting.

The exhibit staged by this company will consist of a 1i ton chassis fitted with a 20 seater char-a-banes body and a 4 ton bare chassis.

The Austin lia.s a four-cylindered nionobloc engine with a bore and stroke of 3a ins. by 5 ins, respectively, the actual b.h.p. being 35 at 1,500 r.p.m. The timing gear is driven by a chain of the silent type. A simple form of chain adjustment as provided by carrying the magneto on a hinged braaet, the top of which is provided with slots which contain studs attached to the crankcase. To tighterirtke`chain it is only necessary to slacken the nuts, and to adjust an ordinary setscrew located in the bracket and pressing against part of the crankcase. The crankshaft is supported in five bearings. From the engine the drive is taken through a single plate clutch with Ferodo friction surfaces to a. gearbox providing four speeds and a reverse. The clutch

and gearbox are constructed as a unit with the engine the change-speed lever

being centrally positioned. The hand brake lever, however, is.. situated on the offside frame member. From. the g:a box the drive is transmitted by a propeller shaft to an overhead worm-driven rear axle, which is of the full floating pattern. Roller bearings are provided for all gear shafts and the wheels. The frame is of channel section pressed steel.

Auto-Carriers, Ltd., Hercules Road, Westminster Bridge Road, London, S.E. 1.

This company have had 15 years' experience in the making of light commercial motor vehicles, and they will be staging a three-wheeled Autocarrier Junior delivery van. This is a light vehicle of simple construction, designed for loads not exceeding three cwt.. The nominal horse-power of the engine is 34, and other points taken from the specification include tubular steel frame, twoeoeed epicyclie gear to overhead weirm drive, internal expanding brakes operated by foot, detachable steel disc wheels, circular rock and pinion steering, and dome mudguards with metal side shields. The body is a panel beaten box, 3 ft. long, 2 ft,. 10 ins, wide and 2 ft. deep. The makers claim that this vehicle will give 60-70 m.p.g.

This company arc the distributing organization for the motorcar depart-, ments of William I3eardmore and Co., Ltd., of Glasgow. Their exhibit will .consist of the 15-20 h.p. Beardmore chassis, designed for taxicab work, and conforming to Scotland. Yard requitemerits. In addition to the chassis, a complete cab, with the company's standard coachwork, will be shown, and also a delivery van on the same type of chassis. The cab has a body of the three-quarter landaulet type, and will be found to provide ample room for three on the rear seat, whilst there is ample space for comfort when the extra seats are brought into .use. There is a luggage platform beside the -driving seat, which is fitted with a hinged door„ giving access to the gearbox. The feature of the chassis will be found in its sturdine-s. the frame' and axles being of very ample dimensions. The radiator is swivel mounted, and the engine and gearbox are on an unclerframe, set at such in angle as to give a straightthrough drive when the vehicle is loaded. The bore and stroke are approximately 80 mm. by 120 mm., and the monobloc engine is provided with a detachable head. The centrifugal water pump, it will be noted, is carried on the rear end

of the fan spindle. There is a silent chain drive for camshaft and magneto, and the carburetter is gravity fed from a tank beneath the driving seat. Threequarter elliptic springs are fitted at the. rear, and the frame is considerably-upswept to give ample axle clearance. Forward the frame is inswept to jirovidc the necessary steering lock, and it will be noted that the steering tie-rod is forward of the axle.

The Belsize stand will be occupied by two vehicles A complete van will be

shown, . and also a taxicab. Both are mounted on the same type chassis, which is the only one made by the firm. The van has a capacity of 12 owt.,-the body dimensions being 5 ft. 4 ins., and 4 ft. in length and width respectively. The height, including the well, is 4 ft; •Pneumatic tyres are fitted, 815 mm. by 105 ram., and the equip ment includes one non-skid and a spare 'tyre and 'wheel. The price of the van is £500, chassis only with -tyres, and of a complete vehicle, as shown, £620. The chassis of the taxi is. slightly different from that of the van in respect of the springing, and the price will be disclosed on application.

Of considerable interest, particularly to thoseinterested in the running of bus services, will he the saloon bus on a Bristol chassis exhibited for the first time by. this company. We recently described. this new chassis in detail, it is. the result of many years' experience in the manufacture of omnibus chassis for running on the company's services in and around Bristol. The saloon bus bodies are constructed as a result of the experience gained in the production of Bristol aeroplanes at the Fitton 'Aeroplane Works. The weight of the 29 seater is 22i cwt. Every -piart is made to template, and it is certainly a considerable advance in motor omnibus construction. The chassis incorporates many interacting features, including centrally-positioned control levers.. The gearbox gives lour speeds forward, and is provided with a novel selector mechanism. From the gearbox the drive is by a propeller shaft -provided with two leather disc universal joints to an overhead worm-driven axle.

In addition to the vehicle, there will also be shown a clutch taken from a chassis which has done 17,800 miles, as well as an open gearbox and other component parts.

*Examille exhibited at Olympia.

Caletlan Motors, Ltd., Duke Street, Glasgow.

An interesting feature of the exhibit of Calerlon Motors, Ltd., of Glasgow, will be the 30-seated Motor coach in which the engine is a 40 h.p. of the Burt-McCollum single-sleeve valve type. This company hold the right for the use of this engine in commercial chassis. The unit certainly gives quiet, smooth, and si'ent running

to the vehicle. The engine by its is eminently suitable for this class of Work, a,ncl the cross shaft mounting of water pump and magneto gives a very high degree of aecessibiiity tathesilriterns. A gcool detail is the three-poinkniounting, which prbtects the engine front the effects of any frame distortion. Transmission on this model is, of course, bylive.axle, and

overhead worm drive by David Brown is used. Fabric universals are used on the clutch shaft., and the .clutch lat a light steel pressing with a Yerodo facing. The propeller shaft has an enclosed • universal at the forward end and a joint of the Sliding block type at the rear. Brake adjustment accessibility will be found a feature rif all CaIedon models, There will be two examples of the 4 ton chain-driven Oaleclon, one with.a tipping betty, embodying a new designuf hydraulic gear. Each has a Dorman engine.

in chassis form, there will be a 6-7 ton model. All th6 types shown ha.ve engines of 40 h.p,

22, to note the several neat little ideas which have this rear been incorporated in the design of this 6:Xeellent chain. driven vehicle. Apart from the soundness of the Tylor engine and the excelleht,design of all other Components:there : is quite a number of ingenious improVe moats. One which, though mall, is quite of importance is the method of Making the brake rods in two parts looped together, thu.s avoiding all risk of breakage, which very frequently takes place owing to vibration when the brake rod is made in one piece. The brake compensation is also remarkably well . car-. rind out. Another point which drivers aspecially. will appreciate is the very accessible lubricators which are fitted for the lubrication of the bevel pinion and

the countershaft bearings. There are several other minor points, which all go to show that a great amount of attention and careful thought have been given to the design of this vehicle.

The short wheelbase chassis will be a handy vehicle for the coal trade. the two main types of steam wagon, the .overtype 'and the undertype, for on that stand Clayton Wagons; Ltd., will display the improved model overtype, as well as the new undertype. Both, it may be said, represent the last word in steam wagon construction, at least up

to date, and the comparison. cannot fail to be interesting. The overtype will be an end tipper, with a capacity of 5 tons. The body capacity is to be 10 ft. by 6 ft. 6 ins., and the price, „complete with tyres, which are ef 160 mm. section throughout, is to be£1,395, Out of which £100 is due to thet wagon being fitted with the tipping gear and equipment. The undertype is a 6 tanner, with plain lorry body, which is 14. ft. long by 6 ft.

6 ins. wide. The same size, tyres are fitted to this as the other, and the price is £1,350. On the same stand will be shown some details of the construction of the undertypo wagon. many years they have been giving strenuous and satisfactory _ service to thOUsands of 'users. The vehicles Which will be shown will certainly do much to maintain, and probably to improve,' this reputation.

The exhibits will comprise one 3P passenger chassis with a special 19 seater char-a-bancs body, in which there are five rows of seats in pairs, all except the central row beng carried right across the body; this central row is provided with a gangway owing to the difficulty of positioning the doors over the wheel arches. The next exhibit will be al34. ton R.C. type chassis with a tilt van body. The two latest productions from the Luton works, the 2G goods-carrying chassis with a capacity of 2 tons, which will be shown bare, and the 30 cwt. Express model, which will be fitted with box van body, will certainly attract. much attention. The 2G and Express models are practically miniatures of °the 31' chassis, except that the Express model has Hotchkiss drive instead of a tubular torque member. Both engines have three-point suspension and the drive is taken through an external cone clutch and fieXible steel disc joint to a threespeed-and-reverse gearbox. • Behind the gearbox in each chassis is the usual type Confiner Car footbralm, and the final drive is by overhead worm.

Daimler..

Daimler Co., Ltd. balmier Works, Coventry. Stand Na. 73.

A single-deck motorbus on the Daimler Co.'s stand is a new model, capable of carrying 29 passengers and the driver. Great pains have been taken with the body of this bus in order to prevent rattle. There are two large windows on either side which fold down when required, and which are fitted with rubber rollers to secure silence. The seating accommodation is luxurious and comfortable, both seats and backs being trimmed with leather with spring upholstery. The body will he shown fitted to a standard Daimler C.K. chassis.

A 25-seater char-a-banes will also be shown. An interesting feaCure of this body is the rattle-proof hood, in which , metal separators between the sticks of the folded hood are used to secure silence. This chassis is fitted with pneumatic, tyres, that can be inflated by a small mechanical pump which is. fitted to the chassis. This pump is also shown as a separate unit. On the char-a-bancs, it is driven by a shaft from the gearbox. A new all-steel tipping lorry with horizontal tipping hoist will also be shown. This body is capable of accommodating approximately a load of two tons, and a control for the tipping gear is hiounted conveniently at the side of the driving seat. The tipping gear is operated, by a small gear wheel pump driven from the gearbox and forcing oil from one side of the piston into the front end of the cylinder, the power being transmitt,A thus in order to tip the lorry. The driver has full control of the lift at any moment, the speed of the tip being limited by the viscosity of the oil. It will be noted that this body is constructed so as to make use of the whole of the space available on the chassis.

,The commercial vehicles produced by this well-known Guildford concern have always proved very popular amongst users. The standard of workmanship has always been high, and great care is displayed in every part of the design. A fully representative display of Dennis vehicles will be at the Show, and -will include a 40 11.p. 3 ton van, a 5-6 ton tipping wagon fitted with hydraulic tipping gear, a 2 ton export model chassis, a 32 seater saloon omnibus, a, 30 seater char-A-banes. and 60 h.p. fire-engine for Tiinidati. of these vehicles two will be new productions, i.e., the 5-6 ton tipping wagon and the 2 ton export model. The heavier model is very similar to the 3-4 tonner, and incluxles the same type of engine, but the radiator is considerably larger, and the rear axle is of particularly. stout construction, employing a cast-steel type cent-re casing strengthened by two adjustable tie rods passing under it. The final drive is by overhead worm gear following the usual Dennis practice. The frame is also con. siderably heavier than that employed on the 3-4 ton model.

The 2 ton export model has centrally positioned controls, and three-point suspension is employed for the subframe on which the engine is mounte41. The gearbox gives four forward speeds, and the back axle is a miniature of those on the larger models.

This company are the sole concessionnaires for this country for the 2 ton Dennis-Portland chassis, which is constructed by Dennis Bros. Ltd., of Guildford. The chassis embodies many interesting and serviceable features, and is designed for hard work, either as a lorry or for the conveyance of passengers. It is made in two wheelbases, 12 ft. and 1.3 ft., the latter being for passenger

work. It hats a pleasing appearance. which is enhanced by its rounded radiator and pressed steel seuttledash. The change-speed control is centrally positioned, as is also the brake lever, the quadrant box and brake. ratchet being securely bolted to a stout, cross member. 'The engine is supported on a three-point suspended sub-frame, the drive to the four-speed-and-reverse gearbox being through a single-plate clutch, and thence by cardan shaft to an overheadworm

driven rear axle. This vehicle has a particularly large -lock, which give ,s turning circle of 46 ft. for the lorry chassis and 50 ft. for thepassenger. . Three examples will be staged. a 2 ion bare chassis, a 2 ton lorry, and a 20 seater char-k-banes on pneumatic tyres.

Here will be found three examples of the 2 ton (useful load) Enfield-Allday commercial vehicle, a well-known model which calls for no introductory remarks.

The three exhibits will consist of a chassis of the long wheelbase type, fitted with Dunlop giant pneumatic tyres, and carrying a handsome 28-seated char-a-. banes body by-John Marston's Carriage

Works, Birmingham, tastefully finished in black and white ; a standard chassis with end tipping body, the tipping gear of which is of the hand-operated,, twin. • screw variety, and a bare chassis showing all the mechanical features, the last two of which exhibits are fitted with 970 ram. by 100 mm. solid band tyres. The specification comprises a four. cylinder 100 mm. by 130mm. engine, developing approximately 25 h.p. at 1,000 r.p.m., a three-speed-and-reverse gearbox, a differential countershaft, and final chain drive to a solid rear axle.

The cylinders are T-headed, and are cast in pairs. A Sthenos or Zenith oarburetter is fitted as standard, but in either ease the throttle is connected to a centrifugal type governor, which is normally set to limit the maximum speed to 12 m.p.h. on top, 7 m.p.h. on second, m.p.h. on first, and 3 m.p.h. on reverse. Lubrication is by means of a rotary oil pump, carried near the bottom of the crank chamber, and driven from one of the camshafts. This pump draws the oil through a filter, and forces it at an arranged pressure to the main bearings of the crankshaft, and through the crank to the big-end bearings. A large-diameter Ferodo cone clutch is employed, and behind the gearbox is found a ratchet type sprag, a device which, in view of our recent articles on the subject of running backward, we are very pleased to see.

The final drivels by chains, which are provided with means for adjustment, and which are totally enclosed in dust and oil-proof cases, which keep the chains free from dirt and well lubricated, thus contributing largely to smooth and satisfactory running. The springing is by semi-elliptics all round. Standard wheelbase, 12 ft. 3 ins.; char A.-bancs wheelbase, 14 ft.

The Foclan stand will contain but one example of this famous make of steam wagon. That will be a five ton standard model with a, plain high-sided body, hay. ing a Boor space of 12 ft. by 6 ft. 6 ins., the sides of the body being 18 ins. high.

Tyres of 160 mm. section will be fitted throughout, the diameters being 850 mm. on the front wheels, which carry singles, those .on the rear wheels being tWins and 1,050 -min., diameter.. The pride' 'Of the wagon, as shown, and complete with tyres, is £1,295.

This well-known company, which is one of the associated companies forming Agricultural and Gemmel.' ,,,Engineers, -Ltd., is exhibiting a 31. ton Garrett elec. tric vehicle with brewer's body, a No. 5 steam wagon chassis, a compound steam tractor on rubber tyres, a 6 ton eide tipping trailer, and a 5 bunk sleeping van.

'The Garrett electric, although built generally in accordance with accepted practice, has certain unique features. The control gear particularly merits attention, it being, designed so that when the vehicle comes to a standstill or the brakes are applied, the control handle must be brought back to the neutral position before restarting. This obviates the possibility of accident through the vehicle starting off at excessive speed and prevents heavy rushes of current, causing damage to the motor or battery. A single series wound motor, capable of ZOO per cent, overload, supplies the motive power, and the drive from this is by silent chain to a countershaft and thence by roller chains to the road wheels.

The steam wagon has a Capacity of 5 tons on the body and 3 toss on the trailer. The boiler is of the loco-type with Garrett's patent corrugated firebox, and can be supplied with or without superheater.The engine is of the overtype, horizontal compound design, the steam distribution being by.piston valve gear. It is mounted on solid rubber tyres fitted on cast steel wheels. The compound steam tractor is u-ed extensively for road haulage, and can be fitted with a governor for driving machinery by belt. It is also provided . with a winding drumeand wire rope. The 6 ton side tipping billet wagon is constructed of carefully selected timber, mounted on laminated springs, and generally designed to suit the road haulage conditions of a fast running motor •vehicle. The body can be tipped to either side as required.

This exhibit will consist of two fine examples of Guy motors, each, of considerable interest, but different in type. The one will be a single-deck Chester type bus, and the other a 21 ton tipping wagon, but, in both cases, the chassis are exactly similar except as to the wheelbase and leading dimensions. The omnibusbody, by Mulliners, of London, is a particularly fine example of . the commercial vehicle coachbuilder's art and, finished in maroon, with leather upholstery to match, it forms quite one of the most attractive vehicles of its type to be seen. This model has a wheelbase of 14 ft. 4 ins., as against the 12 ft. 41 ins, of the tipping wagon. The mechanical features of the two vehicles are identical, the outstanding points throughout the whole design being the accessibility of all important components, and the reduction of upkeep troubles to a minimum.

A four-cylinder engine of, 102 mm. by 140 mm. bore and stroke transmits its power through a cone clutch and four speed gearbox to a rear axle of the double-reduction bevel and spur gear type, which is underalung to give a low platform position. Detachable cylinder heads and large inspection domes in the crankcase render the removal of the reciprocating parts a simple matter without

dissembling the whole unit. .

A commendable feature on the Guy chassis is the three-point suspension of the sub-frame carrying the power and gearbox units. To those persons who are doubtful as to the progress of the chain-driven vehicle, avisit to the Hallford stand will dispel all doubt. Here will be seen the very latest practice in this respect as exemplified on five vehicles: A 2i ton C.C. type chassis with a special collapsable meat van body to the requirements of the Crown Agents, Hong Kong, a 3 ton-E.A. type eha.ssis with a box van

body with lettering in gold outlined in blue on black medallions, a 4 ton B.A. type bare chassis,. and also one fitted with a furniture removal body, and finally a, 5 ton RE. type fitted with hydraulically operated tipping body, which will be shown in operation ; the Wood gear and its pump will be driven electrically for this purpose.

The body of the tipping wagon is eon, structed in varnished teak, and will certainly be one of the, finest exhibits in this line at the Show.

In these chaesis particular care has been taken to enclose the chains in dirtproof and °Might casings. The chains run in oil baths, and are thus most favourably arranged to give long service without trouble. The chaincases are relieved from all stresses by the provision of stout radius rods.

chassis form, and will be found well worthy of a close examination. The engine is a six-cylinder, with the cylinders in two pouPs of three, with detachable heads. The bore and stroke are 3. Ms. by 6 ins., and a high degree of flexibility is secured by the use of very light and accurately balanced reciprocating parts. The pistons are of the Ricardo slipper type, in aluminium alloy, and the confleeting rods are machined all over, as is the crankshaft. The camshaft is chaindriven, and from it is driven a cross shaft by means of skew gearing, at the ends of which magneto and water pump are respectively mounted. Hardy fabric universals are fitted to the clutch and cardan shafts, the latter having a centring device which prevents whipping and undue distortion of the fabric. The final drive is by worm, and the foot brake is carried on the rear end of the worm shaft.

In addition to the chassis, two complete vehicles will be shown, one having a body of the tipping lorry type, hydraulically operated. There are a cab and windscreen for the driver, and the whole vehicle is finished in green. A 29-seated char4-bancs will be an exceptionally smart vehicle of its type, the coachwork having torpedo lines and being very highly finished It will be equipped with e windscreen and electric lighting, whilst the colour scheme will be primrose.

The Karrier thar-a-bancs body is wellnamed " Superb." It is undoubtedly one of the finest examples of the bodybuilder's art to be seen in the Show. We think that Karrier Motors, Ltd., have properly appreciated the fact that in motor coach work appearance and riding comfort will play almost as important a part et they do in the touring car world. We shall have what may he termed " Rolls-Royce " motor coaches and "Ford" motor coaches, and we think that the Karrier body can justly be put in the Rolls-Iles-cc clue. The way in which the wooden framework has been reinforced by metal plate work has made the body exceptionally rigid, and in view of the great care that has been taken to avoid body distortion, which is liable to cause the doors to swing open, it is practically certain that no such trouble could ever be experieece,d with a body built as this one has been.

The bus body is also well worth a close invtion. As some of our readers are pro ably aware, it is built 'under Hickman's patents, and it combines extreme lightness with great rigidity. The building of bus bodies is Certainly a very fine art in these days, but it is one in which Karrier Motors, Ltd., appear to excel.

A road sweeper which will sprinkle the road, sweep up the refuse, and collect it at one and the same time ehould he a very useful machine in these days when the road sweeper's time is such a valuable commodity. The machine which Karrier Motors are showing will, nevertheless, accomplish all these operations at once, and will, it is stated, carry out the work at remarkably low cost. Municipal officials should not miss a close inspection of this machine, especially in view of the rising rates. There is little need for us to emphasize the importance of visiting the stand occupied by this well-known company. They have won a name second to none amongst builders of commercial vehicles, and although the vehicles to be shown are of practically standard design they are certainly worthy of inspection, par i ticularly the new 5 n. by 6 in. 40 hp.

engine on the 5.ton chassis.

In all, four machines will be shown, a. 4 ton 36-40 h.p, model 0 passenger type chassis, with a 33 seater Edinburgh type single-deck bus body, a. 3 ton 30-32 h.p. model C.L. passenger chassis with a. 23 seater char-ashancs de luxe body provided with Smith's electric lighting set. The wheels will be Michelin steel discs shod with pneumatic tyres of the same make, And dome mudguards will add to the general appearance of the machine. The third exhibit will be a 5 ton 40 h.p. model P chassis with a platform body, cab, atanchions and chains, and last, but not least, will be a standard h.p. 500 gallon fire-engine with ReesRoturbo rotary pumps and fitted with a 40 ft. escape.

Two 4 ton McCurd chassis will be shown by this ,company. One will be a hare chassis, and the other will be fitted with a single-deck omnibus body.' The liffcCurd is a well-designed vehicle which received much favourable comment when it was introduced.

The chassis has an engine with a bore and stroke of 4 ins. by 51 ins, respectively, with a massive crankshaft supported by five bearings. The cylinders are T-hecsded, and the cooling is by

centrifugal pump. The clutch is of the external cone type, and the gearbox, which is of very substantial design, gives four forward speeds and a reverse, the pinions being fitted on splinecl shafts. The main shaft rums on five ballraces, and the reverse pinion is idle when not engaged. The final drive is. by an overhead worm mounted in the cover so that it, can be removed without disturbing the road wheels.

Among the steam vehicles at the Show, the Mann production will attract particular attention by reason of its' distinctive design and appearance. It will probably be remembered that the first Mann production was known as a steam cart, and was really intended to he the mechanical equivalent of the horiesdrasvn cart. It has proved to be a vehicle for which a distinct demand exists, but it will not be on view at the Show. The three ton and 'five ton wagons, however, fully uphold Mann's reputation for sound workmanship and robust design. The five ton tipping wagon is a .particularly fine machine, the power-driven gear being a very sound feature.

The new 6 tonner will be the chief innovation on the stand of the Maudslay Motor Co. Seats for the driver and his mate are situated on either, side of the

engine. The steering box, gear' and columns are brought well forward, and as the radiator is used to form "support" for the dash, all space behind the driver's seat is available. The platform behind the driver measures 21 ft. 6 ins., on a wheelbase of 15 ft. 6 ins. There are many ingenious features on this chassis. The steering column provides an oil reservoir from which the steering box is lubricated, the joints being ground in order to prevent leakage of oil. Again, in order to prevent rattle from long lengths of control rods, fan levers are interposed in the brake-operating mechanism. Turn-buckle joints are fitted to these rods in order to secure quick adjustment.. The engine, of conk-se, follows standard Maudslay practice. The two other models shown are the 28 seater char-i-bancs and a side-tipping 5 ton lorry.

An interesting new 3i ton electric, fitted, with a tipping body, will be shown by this company, as well as a large number of photographs showing the various electrical plant manufactured by the company during the last quarter of a century,

Twomotors are employed for driving the machine, one being geared to each of the rear driving wheels, thus dispensing with the differential. These motors are mounted on springs in such a manner that no road shocks can be transmitted to them except through two spring systems in series, and the motors are arranged so that-they can be replaced With the minimum of lost time and without dismantling-the rear axle. The final drive is through one pinion and an internal spur wheel for each motor. The exhibits shown by this well-known Ipswich concern will consid of steam and electric vehicles. As regards gie latter, four in al will be shown, comprising a 2iton chain-driven chassis, which is an entirely new model exhibited for the first, time In this chassis the general arrangement follows the design of the standard' 34 tanner. A 3i ton tipping wagon with two motor drive connected by chains to the rear _wheels, and with a body arranged for refuse_ collection. This is one of six similar vehicles sold to the Hammersmith Corporation. A standard C-type truck fitted with .elevat-, ing table -operated by a separate electric motor, designed for railway work, and capable of lifting 4,000 lb. on the table, and a standard B1 type truck, which is of the three-wheeled type, designed for factory use. This truck has a capacity of two tons. As regards steam exhibits, these will consist, of one of the company's, standard compound steam tractors for trailer work, capable of hauling a gross load of 8 tons, and an improved overtype steam wagon, designed to carry a load of 5 tanson the body _and to haul an additional three tong on a trailer. This machine will be provided with solid rubber tyres. The Ransome steam wagon . is designed to comply with the require. meats of the Heavy Motor Car Act, and has a speed of a m.p.h. The boiler is of the loco type, and is built up of four plates without stays. Provision is made for running the engine as a 'double-cylinder, high-pressure if required, to. facilitate starting and climbing steep hills. The cast,-steel cut gears provide two speeds, and the final drive is through a heavy roller chain to the differential gear on the rear axle.

The range of models manufactured by Walker Bros. (Wigan), Ltd., makers of Pagefield commercial motor vehicles, are well, if not completely, represented on Stand No. 86 by four exhibits, comprising three complete vehicles and one chassis. Fir0t and foremost, again, cornea the motor coach, which will be a standard 28-seater, mounted on the special passen

ger-type chassis (F. long). It is to be equipped with electric lighting, and will be shod with pneumatic tyres, 955 ram. by 155 mm., singles on the front, and twins an the rear. They will be made by the Michelin Co., and will be carried on disc steel wheels, also made bY that firm. The price, completely equipped as shown, is £2,000. The chassis shown is to be a 3 tenser, and is similar to that on which the motor coach is mounted, except that the wheelbase is shorter, the Alistanee

from the back of the dash to the end of the chassis being 16 ft. 4 ins. The tyres fitted are solids, 880 mm. by 120 min., singles on the front Wheels and twins on the rear; the price, chassis only, with tyres, is £1,200. The R. type short wheelbase machine will probably be the only one of its kind in the Show. It has a capacity of N tons, and has the same engine and transmission as the chassis shown. The wheelbase is onl, 8 ft. Sins., notwithstanding that the distance from the dashboard to the end a the frame is 'still 16 ft., only 4 ins, less than the standardPrice, £1,600, fitted with same size tyres as the F type. The fourth exhibit is to be a 5 ton tip wagon on a W.I.!.

type chassis. The price, complete as shown, is £1,775.

The exhibits shown by this company will be a -novel saloon corridor coach on a, passenger chassis, the chief feature of the body being that it is provided with .a special foldang roof which enables it to he used equally well in good 'or bad weather. It is divided bg a centrally positioned partitiOn, and the seats are arranged in pairs on each side of • the gangway. During fine weather the side windows can also be let down. Exceptionat interest will no doubt be created by the springing. This is a new, double cantilever type, which, quite apart from its wonderful resiliency, has many advantages, including a great ref. duction in unsprung weight. The wheels are the well-known Michelin steel disc fitted with pneumatic tyres, twin at the rear and single at the front.

The second exhibit is a bare chassis, in which the gearbox and the box containing the striking mechanism will be provided with glass covers, in order to enable their construction to be seen

clearly. The Palladium chassis have achieved aconsiderable reputation for the quality of the materials employed in their construction, and for their wonderful fuel economy, Whichenfor passenger work, is in the neighbourhood of 9

Flohey anti Co., Ltd., Globe Works, Lincoln.

The Robey stand is another which will be occupied. by one exhibit only, this being a standard 5 termer, equipped with high-sided body, the dimensions of which are 12 ft. by 6 ft. 6 ins. Tyres are of 160 mm. section, 850 rum. diameter singles, solid rubber, on the front, and 1,050 mm. twins on the rear. The price will be quoted on application at the stand.

Ceo. Scamnioll and Nephew, Ltd., Fashion Street, Spitalfields, London, E.

The Scammell six-wheeler is one of the most interesting vehicles which has been developed in this country since the war. It has already been described in detail in our pages, but the Show model, although in essential details it is similar to its predecessor, will incorporate certain improvements which will render it more efficient, both as regards maintenance and running: Wherever possible " handed" parts -have_ been eliminated, and with one exception all brackets can he died right or left band. One size of union is now employed on all pipes. The flywheel has been increased in size, and the pistons have been fitted with scraper rings, which will certainly reduce the oil consumption of the engine; the radiator, also) has been entirely redesigned,_ and the universal joirts on the propeller shaft have been replaced by flexible couplings. This vehicle, although the weight of the tractor and trailer portion together does not exceed -that of an erdinary 3 ton lorry, has a load, capacity of 74. tons without any axle weight exceeding the legal limit of 6 tons for a vehicle designed to travel at 12 m.p.h. It can also pull a trailer weight of 6 tons. The complete vehicle consists of a fourwheeled tractor unit on which is mounted, "by heavy springs fastened direct to the driving axle, a turntable, on which rests the forward portion of the trailer. This has two wheelsgcinly. The trailer braking system is particularly interesting. Apart from the complete vehicle iteelf, there will be another interesting exhibit consisting of a trailer known as the Billingsgate type.

This stand will make a very brave show, as the Sentinel Co., who are to occupy it will exhibit, no fewer than five different Sentinel wagons. All are, of .course, of the same type, _known as the undertype. The vehicles to be shown cover almost the complete range of sizes marketed. There will be two 4 banners, one with t)igh sides, the other with lowsided body. Roth will be on the standard chassis, which has a body space of 13 ft. overall. The tyres fitted will be 'solids, those on the front being of 160 mm. section for 720 mm. rims, and on the rear, -where twins are provided, of 140 mm. section for 771 mm. rims. The next machine is to be a 5 ton end-tipping wagon. The tipping gear is hydraulic, worked by an injector. The body space in this case is 13 ft. inside. Tyres are

• 160 mm. section throughout, those on the front being for 720 ram. rims, single, those onthe rear wheels being for 850 mm. rims, twin. The 6 termer differs, so far as external appearance goes, merely in regard to length and body dimensions, although there are, of course, chassis modifications which die not immediately apparent. The body capacity in this case is 14 ft. 6 ins. inside. The fifth vehicle is of a special type which, as things are at present, may only be used in Liverpool, where the local by-laws allow of an 8 tanner being used. This machine is an 8 tonner for use in that city. In all cases prices may be obtained on application at the stand.

A feature of the Sentinel steamer is the comfort provided for the driver and his mate who are protected by a roomy cab. Sentinel wagons are earning general praise for efficiency and reliability.

Four examples of the productions of this well-known concern will figure at the forthcoming Olympia Show, viz.' a 30 cwt. chassis, 30 cwt. van, with pneu'matic tyres, a 50 cwt. short Wheelbase tip wagon, and a 3 ton chassis, this last model being an entirely. new Star type.

The observant visitor to the Show will notice many points of similarity in the specifications of the three models, the engine, clutch, gearbox, and method of springing being the same in every ease.

The engine has four cylinders, cast in pairs, each having a bore and stroke of 90 mm. and 150 mm. respectively, and is rated at 20 i.h.p., although developing 38 h.p. on the brake. Side-by-side valves, forced feed lubrication, a Fellows magneto, and the Zenith carburetter, with hot air intake attachment, all figure in the engine specification. The clutch is a leather-faced inverted cone, through which the drive is taken to a gearbox, giving four speeds and reverse, and thence by an open propeller shaft to a worm type rear axle in the case of the 30 cwt. and 3 ton vehicles, and to an axle of the double-reduction bevel and spur type on the 50 cwt.

The light van body and pneumatic tyres fitted to the 30 cwt, chassis will appeal to those connected with many industries in which safe transit and low maintenance costs are of more importance than the ability to move heavy,loads. Visitors interested in the latter requirement should not fail to inspect the 50 cwt. and 3 ton models.

The 50 cwt. will be shown with a tip wagon, -and this particular vehicle is of the short wheelbase type. This-point is mentioned, as the 50 cwt. is also made with a wheelbase 2 ft. longer for ordinary trade users, the short typo being introduced for convenience in weighing on standard weighbridges.

Of the 3 tanners, only a bare chassis will be shown, which, except for the new back axle, is similar, but, of course, heavier than the 50 cwt. type. The frame length of this model from the dash is 16 ft., and being extremely suitable far 30-seat char-a-barics bodies, this type will interest many viEiters

The Straker-Squire exhibits, of which three will be shown, should create considerable interest, as the Stralcer-Squire A type chassis is one of the few truly post-war models which will be seen, end all the exhibits will have this new type chassis.

The first is a single-deck omnibus as supplied to the Plymouth Corporation, and is one of 20 which are on order for this town, which is noted for its steep hills.

The second exhibit is a bare chaseis, and the third one, which will prove of considereble interest to municipal authorities, is a new gulley cleaning -wagon, which is built entirely in the company's works to their own design.

Two steam vehicles, one a tractor and the other a wagon, will be' shown by this well-known Andover concern. The tractor will be the famous "Little Giant" of standard type, with a twocylindered compound engine of the overtype and a loop-type boiler built from mild steel plates, with roller chain final drive of special construction known no froaree patent,

The second vehicle is a 5 ton "Little Giant" steam wagon on rubber tyres. This is also a standard model, with a boiler having a working pressure_ of 200 lb. per sq. in. Both vehicles employ cut gears, and in the latter the high and -leipressure cylinders can be used as a double cylinder high pressure engine.

• The exhibit of John I. Thornycro-ft and Co., Ltd., will occupy Stand 56, and will consist of four complete vehicles, the concern having decided not to make any display of stnpped chassis. Foremost in the popular interest will undoubtedly be the fine 28-seater motor coach, which will be mounted on the 3 ton X type diesels. The wheels will be of disc steel, made by the Michelin Co., and will be shod with the same corn. pany's pneumatic tyres, of 155 mm. section and 955 mm. diameter. It will be equipped with a C.A.V. electric lighting set. • Another passenger vehicle on the same -stand will be a single-deck bus, on a

B6

-4 ton J type chassis. Another J type chassis will carry a high aided tip wagon, operated by the Thoreycroft type hydraulic gear, in which the ram is immediately behind the driver's seat, and Efts the front end of the body by cable. The fourth machine is to be a van, fitted on to a 2 ton B.T. type chassis. It is of the same construction as several which are being made to the order of the London and North Western Railway, Co.; indeed, the exhibit may actually be one of the vans for that concern.

Tilling-Stevens Motors, Ltd„, Heiman% Kent.

Three fine vehicles will be shown by this well-known concern, two petrolelectrics and one gear-driven chassis. One of the petrol-electrics is a. 3-4 ton 50 h.p. bare chassis, .which is one of the company's standard post-war models, in which the engine is supported on a sub. frame having three-point suspension, and constructed so that the bottom half of the crankcase can be removed without disturbing the engine ,alignment. A. further improvement is the introduction of internal instead of external dynamo and motor cooling fans, which allow the commutator end covers to be removed without interfering with the fan.. The other petrol-electric model is a standard chassis, with a 40 h.p. engine, slightly modified: to allow for the fitting of a single-deck bus body with a passenger-carrying capacity of 32.

The gear-driven chassis is a 24 ton .stantlard post-war type,laut incerporatligseveral improvements, including a three-point suepended engine, of which the bottom half of the crankcase is removable without disturbing the rest of the engine ; a new clutch, and the provision of a deuble universal joint between the clutch and the gearbox, As the Vulcan is only made in one model, we need hardly state that the four vehicles which will be shown on Stand 51 are all mounted on that type chassis, which has a capacity of 30 cwt. The exhibit will comprise two passenger vehicles and two lorries. Of the former, -one is a motor coach, capable of seating 20 passengers, the other Is a station bus, with accommodation inside for 12, and outside, besides the driver, for two. Both of these vehicles are to be mounted on pneumatic tyres, of 120 mm. section and 880 mm. diameter. Both areto be equipped with electric lighting. The goods carriers are a tip wagon and A farmer's lorry respectively. The former will have a steel body, and lee fitted with hydraulic Upping gear, and the latter will have the overhead-rail loading equipment. Wallis and Steevens, Ltd., Basingatoke.

Wallis and Steevens, Ltd., of Basingstoke, are to show one of their compound steam tractors, which is fitted with Wallis patent enclosed type engine. This tractor is mounted on springs both fore and aft, is provided with two speeds, and fitted with a winding drum. The exhibit is a standard model., and shows no astonishing departure from the practice which has been followed by the makers during the last five years.

W. and G. Du Gres, Ltd., Acton, Middlesex. .

Four complete vehicles will compiie the exhibit staged by this company. They will omelet of a 2 ton chassis fitted with a wood-lined canvas tilt body which has a sliding deer behind the driver's seat giving access to the interior, and rear doors with a safety lock ; another 2 ton chassis with a 20 Witer char-ai-banns de luxe body, painted in green and 'primrose, and upholstered' in light emerald green real hide, fitted with a waterproof hood with patent roller fittings sliding-on brass rods fixed to tb.<3 sides of the body, a double folding type windscreen with adjustable panel for the driver `end dome type wings. An inter. eating point is that giant pneumatic• tyres, will be provided on all wheels, and an air pump for inflatinz them will be' driven from the gearbox. As regards the 24ton chassis, one of these will have a W.D. type body with hinged sides, hoops and waterproof cover, whilst the other will carry a steel end tipping body with a quickly operated hand tipping gear.

An example exhibited at Olympia.

Yorkshire Commercial Motor Co., Ltd., Flunslet, Leeds.

No important departure fromstandard practice will be observale in the steam wagons which the Yorkshire Commercial Motor Co. will be exhibitir g on Stand No.110. ,

The well-known Yorkshire boiler is still retained,and the vertical type of e-ngine which has given such satisfaction in the past.

Steam vehicle construction has benefited by the improvements in material which have been brought about as a result of the war equally with the petrol vehicle, and, in consequence, although design may not have changed appreciably, the materials now used are infinitely better than in pre-war tleye:

From the point of view of economy, the steam vehicle is scoring heavily in these days, and both on that. account, and in view of its handsome appearance and well-known reputation, the Yorkshire wagon is bound to ensure a great (10,4 of interest being taken in Stand No. 10.
