What Is to be Shown by British and Foreign Makers of Petrol, Steam and Electric Vehicles which are Suitable for a Variety of Uses.
IN THE pages which follow we complete our survey of the vehicles which are to be displayed at Olympia, on the occasion of the Commercial iaotor Transport and Roads Development Exhibition, which opens on Thursday next.
If we were asked what is likely to be the most interesting exhibit, we should be at a loss to answer, and if our opinion were sought concerning the most unorthodox design, or the vehicle which offers the best proposition on the basis of price and value in any particular size, we should also find it difficult to express a definite view. .
The Commercial Motor Vehicle Show has always been full of special interest because of the many and varied,, applications to which light and heavy transport units can be put. That interest has increased by leaps and bounds with each succeeding Show,
and on the occasion of this year's Exhibition it promises to surpass with ease all previous records. Not only has the scope of the commercial motor expended to a remarkable degree since the last Show was held two years ago, but the number of types of -vehicles which will be displayed has also been extended to
meet increasing requirements. •
We would direct attention to the developments in the matter of increasing the number of axles pe. vehicle, the striking improvements in steam-vehicle design, the developments which axe taking place in connection with electric chassis, and many other details of design.
The Show will be remarkable as exemplifying the astounding advances which have taken place in the two years which have elapsed, and also because of the vastly increased public interest in the coach.
A.E.C.
Associated Equipment Co., Ltd., Blackhorse Lane, Waltham.
stow, London, E.17. Stand Pt
MHE PRODUCTS of this London company will be repre sented at Olympia by five exhibits : a 2-ton chassis, a 20 h.p. saloon bus—seating 20 passengers, and convertible to motor coach, mounted on a 2-ton chassis—a tractor portion of a 65 h.p. six-wheeledvehicle, a 1,000-gallon oil tank mounted on an A.E.C. model .5 chassis which has a 45 h.p. engine, and anN.S. type double-deck bus to seat 54 passengers.
Of these exhibits most interest will naturally attach to the 2-tonner and to the six-wheeler, as both of these are entirely new designs. The six-wheeler, or the tractor part of it to be shown, will perhaps attract most attention, if only on account of its massive proportions and its simple and sturdy construction. Its four-cylinder engine is of 135 mm. bore and 170 mm. stroke; it develops 65 h.p. at 1,000 r.p.m. All the valves are arranged along one side and a totally enclosed and sealed governor is fitted. Ignition is on the Delco system, incorporating a battery and coil which ensures easy starting, notwithstanding the size of the engine. The clutch is a cone lined with Ferodo fabric and the gearbox affords four speeds, of which the fourth is direct. The whole of the transmission gear is enclosed and the final drive is by overhead worm and wheel.
In order to diminish the liability of a vehicle of this type to overturn when starting suddenly while the trailing portion is still at an'angle to the power portion, the turntable over the driving axle is of unusually large diameter. Still further to ensure the absence of this trouble the sear springs are spaced well a.part, being located quite close to. the wheels.
An interesting point about this chassis is the springing, embodying double volute __springs between, the turntable and the rear end of the tractor frame and long semi-elliptic springs between the turntable and the rear axle. A Westinghouse pneumatic braking system is operated in conjut:action with the hand brake by means of a lever on 4 small column to the right of the steering gear. This pneumatic
C34 brake operates also on the two trailer wheels and, should the trailer become accidentally detached from the tractor, the air-brake immediately operates on the wheels of both portions.
The 2-ton chassis was recently described in these columns. It will suffice for the present to remind readers that it embodies in its design all that is best in motor vehicle construction, special points being the arrangement of the valve gear within the crankcase and of the transmission brake gear within the. gearbox.
Albion.
Albion Motor Car Co., Ltd., Scotstonn, Glasgow. Stand l!3 MILE .AIBION exhibit will be a fairly comprehensive one, ..L embodying six different vehicles—i.e., a 30-cwt. W.D. subsidy chassis a 21-seater saloon bus, a 19-seater Viking motor coach, a:30-cwt. box van, a 2-ton lorry and the latest type 32 h.p. Mark II box van. The general features of the new W.D. subsidy chassis are known to all; the Albion has particular interest inasmuch as it was amongst the first to be accepted by the Was Office autiliorities.
The 21-seater bus, to be shown at Olympia, will be equipped with solid •tyres. If desired, however, this model can be supplied with pneumatics, and, so equipped, it is geared so as to be capable of a speed-of 20 m.p.h. A particularly pleasing exhibit will be the Viking motor coach, which is luxuriously equipped, and built on touring car lines with a well-designed radiator, tapering bonnet, and long low body with deep seats. Particular attention has been paid to ease of entry, and the loading height has been so reduced that only one step is now required.
The 30-cwt. 'box van is a popular type, and the example of this model to be shown should receive the attention of all those users who require a speedy and reliable transport unit.
The 2-ten lorry to be exhibited is one of an order for twenty of this capacity which has been received from the Anglo-American Oil Co. ; the chassis is notable for its coinpactness and the ease with which it can be manmuvred. It is interesting to note that the tyre equipment of this chassis embodies super-cushion tyres of 100 mm. section on the front wheels and twin solid tyres of the same dimensions on the rear wheels. The final-drive ratio is designed to afford a speed of 18 miles an. hour with this equipment:
A feature of all Albion chassis is the inclusion of a mileage recorder as part of the standard equipment. The Albion Co. take the view that the best way to ensure economy of/ transport is for the owner to have definite figures as to the daily mileage of his vehicles so that. he can check consumption and other coats against that mileage and thus be in a position to trace any waste that may occur.
Allchin.
William Allchin, Ltd., Globe Works, Northampton. Stand 123
TilERE WILL be two Alkhin steam wagons on this stand, one of them being. a plain platform lorry with detachable sides, the other a tipping wagon. It is interesting to note that Allehin wagons are all equipped with three changes of speed, the steering on each is of the Ackerman type, and all are equipped with a patent trailer coupling, which, it is claimed, affords improved means of connecting a trailer to a wagon, since it eliminates the neceisity for the man to get between the two vehicles, connection being automatically made when pressure is applied to the coupling by the drawbar of the trailer, when the two vehicles are made
to approach. - The Aflehin wagon is an overtype and the steam distribution to its compound engine is controlled by double-ported fl-type. slide valves, which are controlled by a Stephensontype link motion. The eccentric sheaves are fitted with roller beaTrings.
The rear wheels of the Allchin are interchangeable and equipped with a patented device to facilitate their removal. The foot brake takes effect on drums on the wheels, while the hand brake operates on a steel drum fixed to the rear axle and correaponding in effect to the transmission brake on apetrol chassis. The rear springs are doubled, the smaller one only coming into action when the wage?' is fully loaded; this arrangement conduces to better running of the wagon when running light, thus reducing maintenance costs.
Atkinson. •
Atkinson and Co., Frenchwood Works, Preston. Stand 85
THE ATKINSON exhibit will be one -machine only, the new model wagon, designed for use in billy country and embodying the first application of epicyclie gearing to steam wagon chassis design; the arrangement affords two speeds
and a free engine, "
The usual transmission in the case of an undertype steam wagon, such as the' Atkinson, is a-plain single roller-chain from the engine crankshaft to 'the rear axle. As a rule this is sufficient, as the flexibility of the steam engine as well as, in this type of wagon, the enormous initial -torque Which is available from the two high-pressure cylinders, is 'sufficient, in all-:latW the most exceptional cases, to meet, any power demand . which is likely to arise. Moreaver, where it is known that the wagon will continually operate in difficult country the condition may be met, by modification of the gear ratio in the final drive, such modification being simply and easily effected by the substitution of a driving sprocket a little less than that usually provided. It is now beginning to he appreciated, however, that. there are times when the availability of an extra low-speed gear, for emergency use is a great advantage, and, therefore, in future it will be possible to buy any Atkinson wagon equipped with an epicyclic two-speed reduction gear in which the high gear ratio is 2.8 times that of the other.
Austin.
Austin Motor Co., Ltd., Longbridge, Birmingham, Stand 117
THE AUSTIN display at Olympia will be a representative one, embodying six vehicles mounted variously upon the Austin Seven, Austin Twelve and Austin Twenty chassis. Perhaps the most interesting exhibit upon this particular stand will be the one-passenger taxicab, built on the Austin Seven chassis and costing only £185. There will also he . an Anstin commercial traveller's car mounted upon the same type chassis ; it is claimed that this particular vehicle will run for about 1d. per mile and will carry samples weighing up to 2i cwt., the actual accommodation for parcels totalling
nearly Th 11 cub. ft.. e rear' compartment of the enclosed nearly Th 11 cub. ft.. e rear' compartment of the enclosed i
body s fitted with shelves and a detachable box is fixed at the side of the driver. Another Austin Seven chassis will be staged as a light van designed to carry 2i cwt. There will be a van on the Austin Twelve and another on the Austin Twenty. The former' has a platform area of 5 ft. 7 ins. 'by 3 ft. 8 ins., and the latter affords a body space the corresponding dimensions of which are 6 ft. 5 ins. and 4 ft. 2 MS. The sixth vehicle is to be an ambulance, in which accommodation 'is provided for two stretcher and four sitting cases.
Baico.
Baico Patents, Ltd., 115, Fulham Road, London, S.W.3. Stand 79 MHIS EXHIBIT will embody three principal features, the Baico fire-engine, the Supertonna Summer and Winter motor coach and the new 1924 conversion set of 20-25-cwt. capacity fitted with Ford mechanism to form a complete chassis.
The fire-engine has been especially designed for communitias of five thousand or thereabouts, which. have hitherto relied upon horse-drawn engines; it. is also valuable as an auxiliary for use in large towns and cities. It. is mounted on a Baico chassis and embodies a multi-stage turbine pump of 150-200 gallon capacity 'made by Dennis Bros., of Guildford.
The Summer and Winter motor coach is mounted on the Sppertonata and has 16 seats. For summer use it is equipped with an ordinaty Cape-cart hood, but. in the winter this hood is removed and replaced by a more substantial winter top, which is secured by means of the same fittings which are already provided for the hood.
The 1924 conversion set costs only £65 and, by its use, any second-hand Ford can he converted to carry a load of from 20 cwt. to 25 cwt. In addition to these three items a special 15-cwt. trailer is to be exhibited for the first time; it embodies ingenious means which are used to adapt Ford parts to build up a convenient trailer of moderate capacity It can be drawn by any Ford tonner, and in that way the capacity of that popular vehicle can be nearly Eloubled. On' this stand there will also be shown the Baico aircompressor, which is really an inflation equiproent for garage use. It is capable of supplying 10 cub. ft. of air per minute at a pressure up to 100 lb. per sq. in.
Berna.
Swiss Berna, Ltd., Short Street, London, S.E.I.
Stand
Beardmore.
William Beardmore and Co., Ltd., 112, Great Portland Street, London, W.1. Stand 90
THE BEARDMORE exhibit will consist of two vehicles only—a London taxicab and the new 20-25-cwt. chassis. The taxicab will be Completely equipped as for London service and is a thoroughly fine example of public hire service %ehiele construction.
The lorry iS an entirely new production, for, although it was actually shown for the first time at the Glasgow Show at the beginning of this year, it has been so very considerably modified in the interim that it is to all intents and purposes now being shown to the public for the first time.
It embodies the same engine and gearbox es the taxicab, the former having ithore of 4 ins, and stroke of 4,i ins., the gearbox providing four speeds forward and one reverse. The engine, which has a Treasury rating of 15.6 h.p., actually develops 32 b.h-p. at 1,200 r.p.m. It has a three-bearing crankshaft and side-by-side interchangeable inlet and -exhaust valves, which are made from chrome vanadium steel. The timing gear is chain-driven and adequate means are provided for the adjustment of the tension of the chain. Lubrication is automatic, and the cooling system embraces a centrifugal pump and a belt-driven fan.
The rear axle is of the full-floating type and the final drive is by overhead worm and wheel. The standard equipment of this chassis embodies pneumatic tyres; its weight is 21 cwt., including petrol, water and oil, and it is capable of carrying a maximum useful load of 25 cwt.., excluding the weight of the body, and on the other hand is particularly adaptable for use as a light motor coach, with a. seating capacity for 14 passengers.
Berliet.
Automobiles M. Berliet, 90, Sackville Street, London, W.I. Stand 42 BERLIET commeeciallevehicIes will be represented at
• Olympia by eight exhibits, of which four are chassis and four boinp!ete vehicles. The chassis are : a 15-cwt., 30-cwt., 21-tonner and a 6-tonner, and amongst these the 21-tonner ,T1.c Berlict 2.1-ton special passenger chassis.
has the distinction of be.lig equipped with four-wheel biakes. The 6-tonner is norm-driven, whereas all the ethers have spiral bevel,gears as their mnans of final drive. The Berliet chasris will be found, upon examination, to have that neat and clean in.pearance which is typical of the majority of French chassis, a quality which is obtained as the result of careful forethought. It does not necessarily involve any decrease in accessibility.
A special feature about these chassis is the design of the overhead-valve engine on the 20onner, which is a neat overhead job with large hand holes in the sides of the crankcase for access to its interior. The front-wheel-brake design on this chassis, too, is well worthy of attention. It is particularly neat, and simple and eliminates a good many of the wandering cable attachments which are so familiar a feature of this department of chassis construction. The complete vehicles include a saloon omnibus on a a)-cwt. chassis, a single-deck omnibus on a similar machine, an ambulance built to Local Government Board specifications, and a box van, the two latter being on 15-cwt. chassis.
Bristol.
Bristol Tramways and Carriage Co., Ltd., Bristol. Stand 23 TT IS the intention of -the directors of the Bristol Tramways _Land Carriage Co., Ltd., to show one chassis of each of the two models which they manufacture, as well as one complete passenger vehicle mounted on each type In addition, there will be staged a Bristol engine with the base of the crankcase removed so as to show the details of its construction. There will be a collection of finished parts as fitted to Bristol chassis, and also a gearbox and a change-speed unit electrically operated and demonstrating the Bristol , patent selector gear.
The general specifications of these two chassis are alike, n38
embodying four-cylinder engines, four-speed gearboxes and final drive by overhead worm. The larger machine has an engine of 4 ins, bore and 5a ins, stroke, its nominal rating being 40 h.p. This chassis has a load capacity of 4 tons and is equipped with solid tyres of 1,010 mm. diameter and 120 mm. section, singles on the front and twins on the rear. The smaller chassis has an engine of 3a ins, bore and 5 ins. stroke, nominally developing 30 h.p., and may be had either
solid tyred or fitted with pneumatics; in the former case 865 mm. by 100 mm. are the dimensions, in the latter straightsided cords 34 ins. diameter and 7 ins. section are standardized.
Both the exhibits at Olympia of complete vehicles are to be passenger machines; one, on the 40 h.p. chassis, will be a single-deck omnibus, designed to carry 30 passengers and having front and rear entrances. The interior 35 divided into two compartments, that in the rear being set apart for passengers who desire to smoke. This vehicle is very well finished with domed wings and driver's cab with three-piece windscreen; it is equipped with electric lighting and runs on solid tyres.
The 'bus on the 30 h.p. chassis is of the forward-clash type and has seats for 20 passengers. In this, too, the driver's cab is comfortably enclosed, and has a three-piece windscreen and adjustable ventilators in the front. The lighting equipment is electrical and solid tyres are fitted. It is possible to use this bus as a convenient pay-as-yon-enter machine.
Burford.
(i. Bnriord and Co., Ltd., 24, Haymarket, London, S.W.I. Stand 88
B"rtF°RD productions will be represented by two chassis and two complete vehicles. Of the chassis, the 30-cwt. type N.C. is, perhaps, the more interesting of the two, since it embodies several minor iniprovernents and exemplifies the firm's 1924 production. Among the modifications worthy of note are the fitting of steel disc wheels designed to take special deep-section super-cushion Dunlop tyres, 34 ins. by 4 ins., single on the front, twins on the rear. It, is to have
a radiator a little larger than has previously been fitted
The other chassis is a 2 to 2e-tot-tiler, the B type. This also
is fitted with super-cushion tyres 36 ins. by 4 ins. The wheels, however, are of the wooden artillery type. The 1924 model of this chassis, of which an example is to be shown, has an engine with detachable head, which is an innovation on Burford chassis of this size.
The completed vehicles are both on 30-cwt. chassis, type D, with forward dash. Both have been made to the order of the Great Western Railway Co. to which concern no fewer than 81 have been -delivered during the past few months! One of-them-is a standard railway parcels van, the other is a flat platform lorry. Both of these machines are equipped with Macintosh super-cushion tyres of 34-in. by 3e-in. section. The outstanding feature about Burford chassis, which has been consistently maintained from their inception, es the fit ting of a double-reduction type of rear axle, in which the final-drive spingears are located inside drums on the rear wheels. The chaseis load is taken by a zubstential steel solid axle, to which is bolted the differential casing which contains the filet reduction, which is by bevel pinion and crown wheel.
The makers claim that this construction enables consider able reductions-in weight to be effected, and in support of this claim put forward the following figures :—On a Berinrd 25-30-cwt. vehicle the axle weighs 365 lb., as against 580 lb.; the average weight of a live axle of the same strength. On a 2-tonner the corresponding figures are 600 lb. as against 1,100 lb.There can be no denying the importance of weight reduction in this part of the chassis, since any saving reduces the unsprung weight.
Chevrolet.
General Motors, 1,td., The Hyde, Hendon, London, N,W.9.
Stand 104 General Motors of Canada, Ltd., same address. Stand 33.
ALTBOUGH the General Mofors, Ltd., freely advertise that they are unable to show on their stand at Olympia, a full range of their products, and although this statement is perfectly true—as the lawyerswould say, 'both in substance and in fact—yet it cannot be denied that there will be on their stand, and on those of firms allied with them in some way or other, a very representative selection of Buick, Chevrolet and G.M.C. commercial vehicles. So numerous, in fact, are these exhibits that we can do no more, in the space which is at our command, than enumerate them.
They comprise a Buick 15-cwt. chassis and an attractive 15-cwt, van on the same sub-structure. There is also to he a traveller's brougham neatly designed to give the same appearance as a private brougham and equipped with a wide door at the rear and long .vestibule doors each side of the driver, and this also is on a 15-cwt. chassis.
On a G.M.C. chassis there will be a 26-seater saloon body, withpay-as-you-enter equipment, and -also a 17-seater of the same type. There will be a 14-seater charek-bancs de luxe, also on a G.M.C., and a 30-cwt. van. Chevrolet products will be represented by a 10-cwt. van and a traveller's brougham on a similar type chassis; a one-ton chassis, a. one-ton van and a 14-seater pay-as-you-enter omnibus, all on one-ton Chevrolet chassis.
Amongst the G.M.C. exhibits of particular interest which may not be found on the stands either of General Motors, Ltd., or on that of General Motors of Canada, Ltd., mention must be made of the 15-ton G.M. tractor which is being shown by R. A. Dyeon and Co.; Ltd.
Clayton.
Clayton Wagons, Ltd., Titanic Works, Lincoln. Stand 16
THERE WILL be three vehicles on the Clayton stand, one of each principal type Manufactured by Clayton' Wagons, -Ltd., these consisting of one electric Vehicle and two steam wagons; the óf-the latter being an tindeetyPe and the other
an overtype. • . The special features of Clayton .electrics are the arrangement of the single motor unit; Which has combined with it the countershaft bearings and the housing for the gears The advantage of -this construction is that there can be no trouble due to faulty alignment. The particida,r vehicle to be eliewn on the stand will be atieping wagon of the " run-hack "type and fitted with 'steel body. •
The undertype wagon to he displayed is fitted with plate form body suitable for general haulage work. The outstanding features of this type of Clayton wagon are the vertical
water-tube boiler, which is fired through the centredoor at the top, the use of a superheater and the provision of 'cleaning
doors near The bottom of the boiler, which reeilace the screwed
plug type generally used. The steam' distribution valves of this type of Clayton wagon are unusual, consisting of piston valves operated by ingenious valve gearing.
The front axle is carried on long laminated springs and the wheels are centrally pivoted in such a way as to allow of the use of Ackerman steering gear, without the need for overhung bearings. Clayton overtype wagons are made with either tractionengine type or Ackerman type steering gear, the particular model to be exhibited will be equipped with the farmer arrangement. This vehicle will be fitted with a tipping body which is operated by a most ingenious gear, embodying a small rotary steam engine operated by steam taken direct from the boiler
,Citroen.
Citran Cars, Ltd., Brook Green, Hammersmith, London,
W.6. Stand 21 0 NE of the most interesting stands at the -Show will be that upon which Citroen vehicles are staged. These makers' productions will be represented by six vehicles—a 7.5 h.p. delivery van for 2e-cwt. loads, a 11.4 h.p. for 7-cwt. loads, and a 11.4 h.p. farmer's wagon, the loading capacity of which also is 7 cwt.
The most interesting exhibits, however, will undoubtedly he the two Citroen-Kegresse chassis, one of which is to be fitted with platform body and the other with a torpedo van body. The sixth exhibit is a Citroen taxicab. The Citroen-Kegresse chassis is similar in general design to that which made the famous crossing of the Sahara Desert earlier in the year Instead of wheels this vehicle has an endless-band attachment similar in principle to those used on the Tanks, the difference being that, whereas the latter vehicles had metallic shoes and were, consequently, somewhat noisy, this Kegresse trackis an-endless flexible band. There
is a special change-speed gear embodied in the construction of this chassis _which affords six forward speeds and two reverse. •
The other vehicles embody, as standard, 'four-cylinder engines, three-speed gearboxes, and spiral-gear final drive. Particular interest will undoubtedly attach to the farmer's wagon, which has a couple of comfortable seats in the front and well-designed utility body behind, the whole being -covered and protected by one hood of the usual Cape-cart type The taxicab is, of course, London-type design to conform to Scotland Yard regulations.
Clement-Talbot.
Clement Talbot, Ltd., Barlby Road, London, W.I0. Stand 9 MIIIS company will exhibit two complete vehicles, an
ambulance and a 14-seat motor coach. Both are mounted on examples of the 25-50 h.p. Talbot chassis, which embodies an engine of 101.5 ram. bare and 140 nine stroke. The load capacity of the ohassis is 30 cwt., and it is equipped with pneumatic tyres of 820 aim. by 120 mm. section, twies on the rear and singles on the front. The ambulance is designed to carry either two stretcher cases and one stretcher case with two or three sitting patients. It may also be used to convey six sitting-patients and an ettendant. The cab is arranged to accatrimoclate two people besides the driver, and the equipment includes two reof lights and one hand lamp, an electrie 'fan, roof ventilator, etc..
The Motor coach is of the open touring type. It is painted dark red with upholstery to match, the equipreent including electric lighting and starting, clock, speedometer and electric horn.
Crossley.'
Crossley Motors, Ltd., Gorton, Manchester. Stand 31
CROSSLEY'S intend to show three machines-aan ambulance, a chassis and a tender. The first of these is mounted on a 25-30 h.p. Crossley chassis similar to those used in large numbers by the Army authorities. The chassis is completely equipped, with pneumatic tyres 895 mm. by 135 mm. on Rudge-Whitworth wire wheels, electric lighting and starting. The ambulance body is fitted with two stretchers, first-aid cabinet, wash-bawl and interior lights. The exterior is to be painted red, and the inside will be white enamelled.
The chassis to be exhibited is the new 30-cwt. Government, subsidy vehicle, and this exhibit is of particular interest, as it affords an opportunity for examination of the chassis constructed to this specification. Its engine is a four-cylinder, with a bore and stroke of 4 5-16 ins. and
5i ins. respectively. The clutch is a cone, the gearbox affords four speeds and reverse, and the final drive is by spiral-bevel gear. The wheels are of special Crossley type, made of aluminium, and designed to take Dunlap aero-cord tyres of 920 mm. ny D-section, twins on the rear, singles on the front.
The third exhibit is a complete Crossley tender built to this new W.D. specification. It has the same chassis as that to which reference has already been made, and is equipped with a body fitted with detachable canopy, separate driver's cab, Kopalapso-type hood, paraffin side lamps and tail lamp and acetylene headlamps.
Daimler.
Daimler Co., Ltd., Coventry. Stand 02
THE DAIMLER Co., Ltd., will be exhibiting a motor coach, a double-deck omnibus, a tipping wagon And a sectional chassis. The last-named is an example of the substructure of the other three, embodying a 22.4 h.p. engine, four-speed gearbox and worm drive. The chassis is fitted with solid tyres.
The other three vehicles differ, ap.art from the bodies with which they are fitted, in their tyre equipment, the motor coach having pneumatic tyres of 955 mm. by 155 mm. section, singles on the front, twins on the rear. The omnibus has 26-in. by 8-in. Dunlop single pneumatics on the front and Dunlop solid tyres of special section on the rear. The tipping wagon is mounted on solid tyres 100 mm. section for 771 min. rims.
The motor coach is a well finished vehicle, having a seating capacity for 20 passengers. It is painted carriage green, picked out in white lines and upholstered in leather. The double-deck omnibus body, which has been made by Christopher Dodson, Ltd., seats 34 persons, including the driver. It is painted red. The tipping wagon has a steel tipping body with a capacity of 120 cubic ft. The tipping gear is of the horizontal single. rani hydraulic type.
De Dion.
De Dion-Bouion, Ltd., 10, Great Marlborough Street, -London, W.1. Stand 112 CHASSIS only will be shown at Olympia by De DionBoutoa, Ltd. Those exhibited are three goods chassis for 20-30 cwt., 30-40 cwt., and 3-1 tons. The fourth exhibit C38
is a passenger chassis with a capacity for a 20-seat coach. The two smaller goods chassis and the passenger chassis are entirely new models and have not hitherto been seen on this market. Dealing first with the goods vehicles, thee e embody four-cylinder engines with a power rating, according to R.A.C. formula of 17.9 h.p., the bore and stroke being 85 mm. and 130 mm. respectively.
The clutch in each case is a multi-disc, and the gearboxes provide faur speeds forward and a reverse, the final drive being by spiral bevel gear. The equipment of the smallest model includes Michelin tyres of aeo mm. by 120-mm. section, singles on the front and twins on the rear, and dynamo lighting and starting. The larger of these models has pneumatic tyres of 895 mm. by 135 mm. section, also singles on the front, twins on the rear, but not electric starting and lighting. The passenger-type machine is a 22.4 h.p. engine with 95 mm. bore and 1401 mm. stroke. It also has a fourspeed gearbox and bevel drive, and is equipped with pneumatic tyres of 956 mm. by 155 mm. section. The equipment includes-front-wheel brakes and electric lighting set, but no lamps or starter, at the standard price. Front-wheel brakes, too, although embodied in the chassis specification, are only fitted at extra cost.
The 3i-tonner has a four-cylinder 100 mm. by 140 mm. engine of 24.8 h.p., multi-disc clutch, four-speed gearbox, spiral bevel drive, and is shod with solid tyres' of 930 mm. by 120 mm. section, singles on the front, twins on the rear.
Dennis.
Dennis Bros.., Ltd., Guildford, Surrey. Stand 01
THOSE WHO are interested in the latest type of firefighting apparatus will be well advised not to miss the Dennis stand, upon which will be staged, as one of this company's exhibits, a chassis of one of the latest type 60-70 h.pa 500-600-gallon fire-engines, equipped with the Dennis patent multi-stage high-pressure fire-pump, which, amongst many interesting features, is notable on account of its light weight, having in mind its capacity. It will be noted that the pump is driven by gearing which is mounted at the front end of the chassis gearbox and enclosed in an aluminium casing, the drive from this gear to the pump itself, which is, of coarse, located at the extreme rear of the chassis, being effected by a long cardan shaft, which is equipped with a flexible disc joint at the eath end and is supported at about the middle of its length in a journal which is carried by a cross-member of the main chassis.
Another example of the fire-fighting equipment, which comes from Guildford, is the Dennis 200-250-gallon trailer fire-pump, which is a portable outfit mounted on a pair of wheels so that it may conveniently be towed either manually or in the rear of a car. This outfit, too, embodies the new patent pump to which reference has already been made, ancl the unit itself has many ingenious and interesting features, such as the quick-acting articulated struts which support it and maintain its equilibrium after it has been detached from the hauling vehicle and is at work.
Amongst the motor coach exhibits at the Show there will be few which will be more attractive than the four-purpoSe saloon motor coach mounted on the special Dennis 30 h.p. passenger-carrying chassis, The bodywork of this vehicle embodies the latest and the most efficient type of all-weather fittings. %Entrance is effected by one door only at the nearside front of the body, and passengers reach the rear seats by means of a central gangway. The equipment of this coach is such that it may be used either (1) entirely open; (2) as an open coach with hood down and side frames up, to act as wind and dust screens; (3) with hood up and windows down; and (4) entirely closed, Another passenger vehicle on this stand will be a 48-seater double-deck London-type bus, in which the 40 h.p. chassis is employed. The new Dennis 20 h.p. 20-25-cwt. worm-drive chassis will be shown as such, and also equipped with a 12 to 14seater hotel bus body upholstered in grey Bedford cord. A full' description of this new production will be found elsewhere in this issue.
Another exhibit will be a chassis with a 2-24-ton capacity which has a 30 h.p. engine, and exemplifies Dennis standard construction, and, finally, there will be a convertible vehicle which can be used as a cesspool emptier and a three-way hydraulic tipping wagon.
Dodge Brothers.
Dodge Bros. (Britain), Ltd.Stevenage Road, London, S.W.6. Stand 30
THE Dodge Bros. exhibit include two chassis and two complete vehicles. The former are the 24-35 h.p. Dodge chassis and the Graham Bros.' 30-ewt.,truck chassis, which is fitted with Dodge Bros. power plant. The small chassis has a four-cylinder engine of 3,7s ins, bore by 41 ins. etroke, threespeed gearbox with central change, multi-disc clutch and spiral-bevel gear. All the brakes take effect on the rear wheels, which are of the wooden artillery type, and accommodate 32-in. by 4-in, straight-sided cord types. The equipment includes electric lighting and starting, speedometer and tool kit,
The other chassis, of course, has the same power unit, but its tyre sizes are 33 ins. by q ins, on the front and 36 ins. by 6 ins, on the rear. The 15-cwt. panel-type van will be shown on a Dodge chassis, and a saloon bus on the Graham. The latter is by Roods and Bodies, Ltd., and is of the pay-as-you-enter type. Its capacity is for 16 passengers.
Durant.
Durant Motors, Ltd., Trading Estate, Slough, Bucks.
Stand 37 THE OUTSTANDING feature of the Durant .exhibit will be the Du'ple van, which, as its fore-shortened name should imply, is a vehicle which fulfils a double purpose; as its manufacturers aptly put it, this car is really two cars, but needs only one garage, one licence and one insurance. It is built on the Durant standard touring car chassis, which is equipped viith two quickly interchangeable bodies—one an ordinary touring four-seater, the other a neat van. The design is most ingenious' as, in substituting the one for the other, complete removal of the main portion of the body is unnecessary. The touring car body merely loses the extreme rear portion carrying the rear seats and back squabs with the hood and fittings. The van top then drops on to the remainder of this body, and may be secured by simple means, necessitating no tools, not even a spanner. The appearance of the vehicle, either as a van or touring car, is both smart and pleasing, and the price, £280, bears out the company's contention that 4t is two cars at the price of one.
The other exhibits are the 10 cwt. van and the 15-curt. Both ace equipped with British-built bodies of steel and seasoned ash. The general specification of the Durant chassis are alike, embodying four-cylinder Continental engine and dry-disc clutch; separately mounted three-speed-and-reverse gearbox and three-quarter floating axle with final-drive gear by spiral-bevel pinion and crown wheel. Both brakes take effect on the rear wheels, and the suspension embodies halfelliptic springs both front and rear, the latter being under
Fiat.
Fiat Motors, Ltd., 43-44, Albemarle Street, London, W.f.
Stand 106
THE Fiat is another representative exhibit, this company staging no fewer, than nine vehicles, which we may briefly enumerate as follow—A one-ton utility truck, mounted on the F2 chassis of 15-20 h.p.; •the bodywork is suitable for
general-purpose haulage, and has high sides and hinged tailboard with step. It. is equipped with detachable sheet and windscreen. A steel-panelled van, with double doors at the rear on the same type, and, again, still on model F2, an hotel omnibus designed to seat 10 passengers inside and two on the driver's seat. This bus has frexaeless drop windows, leather upholstery, a roof rail for luggage, an accommodation ladder and full windscreen.
Another exhibit is the Fiat Wandsworth-type ambulance, also on an F2 chassis, and designed to carry two stretcher or six sitting cases. It is fitted with automatic heater, washbasin, medical appliances, etc. The seats may be folded away in the sides of the body when not required. Particular attention has been paid in the design to facilities for cleanliness, all internal corners being carefully rounded off. The equipment includes electric lighting and illuminated ambulance sign. The only chassis exhibit is of the famous 15-ter, now revised and improved. This machine -has a 25 h.p. engine of 100 mm. bore and 140 nun, stroke, with four forward speeds and reverse. Its load capacity is 30 cwt., and it is fitted with pneumatic tyres of 880 mm. and 120 mm. section; singles on the front, twins on the rear. Another exhibit is a 16-seater pay-as-you-enter service omnibus, designed to accommodate 16 passengers on crossseats with centre gangway. The front entrance is controlled by the driver, but an emergency door is fitted at the rear. There will be a, 31-ton lorry of the well-known 13 BL type;
10-owt. Fiat boxvan, mounted on the new chassis which was recently described in full in The Commercial Motor, and also the Fiat taxicab of Scotland Yard type.
Foden.
Podens, Ltd., Sandbach, Cheshire. ' Stand 102
MHE Foden exhibit at Olympia will consist of three J_ vehicles—two 6-tormers with long platform bodies and a 5-tonner three-way-tipping wagon, the latter being particularly suitable for municipal work, road making, and so on. Of these exhibits most interest will naturally attach to the 6-tonner, which is a new model this year. This chassis follows Foden regular practice in the main : that is to say, it embodies an overtype compound engine) locomotive boiler and transmission by chain to a differential on the rear axle. In comparing the specification of this new model with that of the 5-tonner, certain modifications become apparent. These have been necessitated partly to enable the new chassis to carry its increased load and also as a result of the progress in design which is. continually going on.
Taking the former points first, there is an increase of a quarter of an inch in diameter in both the high and lowpressure cylinders, the stroke remaining the same. The beating surface and grate area of the boiler have necessarily been enlarged, in order to afford the extra steaming Capacity.
The boner pressure is increased, being 220 lb. per square inch in the new model, as against 200 lb. previously. Necessary increases in the dimensions of the engine parts have been made in order to Cope with the increased power which will be afforded by the combination of the higher steam
pressure and larger cylinders. These and the necessary stiffening of the main components of the chassis, to enable them to cope with the additional loading, comprise the modifications brought about by the change from five to six tons. Other alterations include the substitution of a three-speed gear for the two-speed gear which has hitherto been usual, the use of Ackerman-type steering instead of the tractionengine variety, as well as slight modifications in the brake gear. The 5-tonner which forms the third exhibit, remains practically unaltered.
F.W.D.
Four Wheel Drive Lorry Co., Ltd., 46, Charing Cross. London, S.W.1. Stand 40
U.W.D. exhibits compriseone standard chassis a three...1.2 way hydraulic tipping lorry and a tipping trailer, a long wheelbase chassis with fiat platform body, and a fire-engine. The chassis will be polished and specially arranged so as to show the principle of the four-wheel driving mechanism. To illustrate its adaptability, either as a road vehicle or as a four-coupled locomotive, this chassis will be fitted with the latest type steel wheels designed to take either 40-in. by 8-in. Giant pneumatic tyres, 36-in. by 6-in, solid rubber tyres, or flanged railroad rims.
The tipping lorry and trailer are equipped with Bromilow and Edwards three-way hydraulic tipping gear, which can be operated from the driver's cab on the lorry. The trailer is coupled to the lorry by a telescopic tube with ball joint connections. Both the bodies have sheet-steel floors, so as to facilitate tipping the load, and the design in general has been improved so that the loading level is now 3 ins, less than that which has hitherto been customary. it. is important to note that both the lorry and trailer are equipped with Westinghouse air brakes, a feature of which is that, should the. trailer become accidentally detached from the lorry, the brakes are automatically applied to both vehicles. The long-wheelbase chassis is an innovation for this company, and it is designed to accommodate a flat platform body 16 ft. long and 7 ft. wide. The frame is a massive piece of work, being of pressedsteel and having a maximum depth of 8-1 ins.
The fire-engine is Dennis-pump equipped and has a capacity of 2.50 to 300 gallons. It, is fitted with pneumatic tyres 40 ins by 8 ins, and a C.A.V. lighting Set. •
Garford.

Garner.
Henry Garner, Ltd., Moseley Motor Works, Birmingham. Stand 28 01TESTANDING exhibit on this stand will undonbt edly be the G-arner Salaam Busvan. This is designed to be used, on the one hand, as a comfortable passenger-earrya ing vehicle; or, on the other hand, solely for the conveyance of goods • or, again, intermediately for carrying both passengers and goods without inconvenience to the former or detriment to the latter.
The conversion is rendered practicable by the use a C40 collapsable seats, which, when not in use, fold neatly against the walls of the van; in that position they take up but little room, and do not appreciably reduce the internal cubit: capacity of the vehicle. They are useful, too, as protecting the flexible windows of the vehicle from damage by the goods. When required for passenger conveyance, these seats are let down and firmly but quickly secured to the floor of the body. Just so many as are needed for the conveyance cif the passengers may be let down, those at the front being utilized first, leaving space at the rear for goods.. Entrance for passengers is by a single door at the front near side of the van, and for goods through aconvenient tailboard arrangement at the rear. The model of this vehicle which is to be staged at Olympia embodies several modifications and improvements which have not hitherto been available. For example, the collapsable seats are now upholstered in cord cloth instead of leather, the front wings are of a special domed pattern with inside shields, and the windscreen is of glass, with rubber insertion to prevent rattle and consequent damage. The front rianieboard is now eliminated, and its absence has the effect of improving the ggneral outline, giving the bus the appearance of a private passenger-carrying vehicle. The other exhibit on this stand will be a general-purpose lorry with hinged detachable sides, capable of being converted into a platform lorry. Att.erition is directed to the arrangement of the driver's cab, which shows evidence of considerable thought having been given to the comfort of ite prospective occupant.
Garrett.
Richard Garrett and Sons, Ltd., Leiston, Suffolk. Stand 87
ACOUPLE of steam wagons and a trailer are being shown by Richard Garrett and Sons, Ltd. The exhibit No. 1 is a most unusual one for a steam-wagon manufacturer. It is described by them aa a specially Show-finished chassis of the Garrett 6-ton undertypa steam wagon, equipped with a temporary. driver's seat and a special aluminium crankcase. Special points of interest about this machine are the use of roller bearings throughout the chassis, the change-speed gear, and the facilities for cleaning and expanding the boiler tubes, this last-named operation being possible after removal of an inspection door which is let into the front of the boiler shell. The control of the wagon is by accelerator pedal, designed to enable the driver to govern the speed of the wagon entirely by its use, leaving him free to steer and drive as in the case of a petrol vehicle.
The second exhibit is a standard steam wagon body with canopy for the driver's seat as usually fitted to this 6-ton undertype steam wagon. a
The third exhibit is another specially Show-finished chassis of the new 3.4-ton Garrett self-tracking trailer. The particular points of interest about this are the fitting of a simple mechameal device which enables the trailer automatically to follow in the tracks of the hauling vehicle; the Ackermantype steering; the preesed-Steel frame, and the pressed-steel-wheels, which are shod with solid-rubber tyrei and run on idler bearings G.M.C.

Gray.
Ancona Motor Co., Ltd., 73442, Brompton Road, London, S. W .3. Stand 10
AN entirely new range of commercial motor vehicles is exemplified in the Gray chassis, which are being shown by the Ancona Motor Co. The exhibits on this firm's stand will include a 1-ton chassis, a 10-cwt. Van, a tra.veller's,two-. seater box car, and 1-ton delivery. van. The general specifications of the two chassis are alike, embodying four-cylinder 'engines of 21 h.p., having a bore and stroke of 3/ ins. and 4 ins.; the engine is thermo-siphon waled, with the assistance of a fan, and the lubrication throughout is by splash. The equipment includes starting and lighting outfit and battery and coil ignition. The gearbox embodies three forward speeds and is equipped with a
central gate. Final driy.e is by spiral bevel gears, and the brakes take effect, one on a drum behind the gearbox and the other in the rear wheels.
An interesting feature of the brake gear is the mounting of the hand brake and the external-contracting shoes on a Steel casting, which is bolted to the gearbox. There is no transmission at all to this brake, as the lever is secured direct to the brake earn spindle. The outstanding feature of this exhibit will, be the low prices, the 10-cwt. costing only 2135 and the 1-tonner £175.
G.V.
General Vehicle Co., Ltd., 43; Shoe Lane, London, E.C.4.

THE General Vehicle Co. are showing one of their new 10-ton sit-wheelers, and with this exhibit we now have a six-wheel type of chassis, made in all constructions and for either steam, petrol or electric power. This model is equipped with Westinghouse air brakes. The same company are showing a 31-ton chassis with all-steel galvanized and tipping body of 9 cubic yards capacity. This vehicle has been specially designed for municipal work and particularly for house and trade refuse collection. The tipping gear is electrically operated, and a full load can he discharged, it is claimed, inside 90 seconds.
A particularly interesting vehicle is the C.V. 2-ton chassis, mounted with e box van body designed for general carrier's use, a special feature of it being the ease of access to the interior from the driver's cab. The G.V. Co. are also showing three examples of industrial trucks, one being the Hylift of 2-ton capacity with two-wheel drive, but steering on all four wheels. The loading platform of this 'truck can be elevated to a height of 6 ft.

The equipment includes chemical extinguishers and a light ladder ; the tyres fitted are pneumatics of 820 mm. by 120 mm. section, singles on the front, twins on the rear, mounted on disc wheels. The third exhibit is an 18-seater saloon coach body mounted on a 30-cwt. chassis. This is a luxurionsry finished vehicle, painted yellow from base to waistline and black above that line. The upholstery is antique leather. Another attractive motor coach to be exhibited on this stand is the 20-seater, which is mounted on a 25 h.p. chassis. This has been designed so that its appearance is very similar to that of an enlarged touring car ; the boarding level is very low and the outline is attractive) with tapering bonnet, scuttle dash and torpedo-type bodywciala . Pneumatic tyres are fitted of 895 mm. diameter by 135 mni. section, singles on the front, twins on the rear.
The fifth exhibit' is also a passenger vehicle, being a 25-seater "pay as you enter" single-deck bus, mounted on a 2-ton 25 h.p. chassis, The tyre equipment in this case are solids of 100 mm. by 720 mm. singles on the front, and 110. ram. by 720 mm. twins on the rear.
Halley.
tialley's Industrial Motors, Ltd., Yoker, Glasgow. Stand 114
AS their principal exhibit at. Olympia, Halley Industrial ..Motors, Ltd., are showing one of the larger tape fireengines. This has a capacity of 500 to 600 gallons per minute and is equipped with a six-cylinder engine of '75 h.p to 95 h.p. The engine itself has a, bore of Sins, and I. stroke of 64 ins and drives through a single-plate clutch to a fourspeed-and-reverse gearbox, thence to a worm-driven rear axle. An auxiliary gearbox fitted between the clutch and the main gearbox encloses the transmission from the clutch shaft to a double universally jointed propeller abaft,, which drives the pump located at the'extrerne rear of the chassis.
Dual ignition is employed, and there is also an auxiliary geared pump, which draws its supply of water either from a tank or from a hydrant, and pumps it through a first-aid hose reel which is mounted on the top of the body. The pump and exhaust form a unit which is extremely accessible. It is built throughout of gunmetal and is not liable to damage as the result of pumping. unclean water. The capacity of the exhauster is sufficient to enable it to lift water from a depth of 28 ft. in under one second per foot.
Another exhibit is a 750-gallon vacuum-type gully and cesspit emptier, designed so as to be available also for use as a road sprinkler. This outfit is fitted on to a standard 4-ton Halley chassis. It has asix-cylinder 35 lap. engine, which has a bore of 3 ins, and a stroke of 6 int, and drives through a single-plate clutch, four-speed-and-reverse gearbox, to a worm-driven rear axle. The cesspit emptier Is of the Warwick type, comprising a mild-steel tank of 750 gallons capacity, in which a vacuums is created by means of a rotary pump bolted to, and driven direct from, the main
gearbox. By a special arrangement of piping pressure can he applied inside the tank so as to facilitate discharge, which can be arranged to take place at some distance from the vehicle.
A refuse-tipping wagon fitted on to a forward-dash type 2-ton to 2k-ton 25 h.p. chassis, is the third exhibit. Owing to the empioyment of the forward-dash principle, it has been possible to provide a body of 13 ft. by 7 ft., notwithstanding the fact that the overall length of the vehicle does not
exceed 17 ft.
As regards the bodywork, this embodies special sliding covers, fitted to prevent refuse from being blown about. Only one-sixth of the body need he open at any time for loading. Its capacity is approximately 150 cubic feet. On the vehicle which is to be shown the tipping gear is handoperated, but hydraulic gear can be supplied if required.
Another of these forward-dash 25 h.p chassis is shown equipped with a 20-seater single-deck bus. It is worthy of note that the rear-axle ratio is modified for—passenger work and that the equipment includes electric lighting.
Hanford. • J. and E. Hall, Ltd., 10, St. Swithin's Lane, London, B.C.-I.
Stand 107 LTALLFORD exhibits are fairly comprehensive, including
Ivehicles for loads of from 35 cwt. to 10 tone inclusive. Taking these vehicles in order of size, the smallest is a brewery. van, mounted on the 35-cwt, chassis, which has a 25 h.p. engine. The next exhibit is a chassis ony, 4-ton capacity, with a 32 h.p. engine, four-speed-and-reverse gearbok. Three of the exhibits are of the same capacity, i.e., 5 tons. One is equipped with a general service body, with open-frame sides, supplied to the order of a London haulage contractor. It is equipped with towing gear, so that in case of need it may be need for beating a trailer. The next is a tipping lorry, such as is regularly supplied by,J. and E. Hall, Ltd., to municipal authorities, haulage contractors, and so on. The tipping gear is hydraulically operated.
a
The third 5-tonner is a 1,200-gallon oil tank. This-is built in accordance with the requirements of the L.C.C., and is one of the latest designs of the Steel Barrel Co., of Uxbridge. The tank is of D-shape and has three compartments, the usual fire shield is fitted behind the driver's cab between it and the tanks and the equipment includes electric lighting by C. A. Venaervell and Co. The largest vehicle is the 10-ton six-wheeler. This machine has a 40 h.p. engine, a four-speed-and-reverse gearbox, and is equipped with the patent Westinghouse pressure brake, operated by exhaust. from the engine. This gives the necessary control over the vehicle without any physical exertion or fatigue on the part of the driver.
Karrier.
harrier Motors, Ltd., Huddersfield. Stand 109 A MONO the Karrier exhibits at Olympia the 20-cwt. to .t1_25-cwt. chassis will probably attract most attention on account of its novelty. It has been described quite recently in The. Concrnercicrl Motor, and there is, therefore, no necessity for our entering into a detailed description of it now. It may be worth while, however, to -point out that the construction embodies the unit-mounted engine and gearbox, the former being of 18.2 h.p. and the latter affording four speeds forward and a reverse. The engine is of the behead type, with all the valves down one side. The clutch is a multi. plate, with fabric lining, andthe transmission behind the gearbox is by flexibly jointed tubular propeller shaft,, the 042
rear axle gear being overhead worm and wheel. The two sets of brakes act on transmission drums and on the rear wheels, and the equipment includes a mechanically driven tyre pump for the pneumatic tyres and a speedometer, driven through skew gears from the rear end of the worm casing.
There will be on this stand a pay-as-you-enter bus, with a capacity for 20 seats, mounted on a standard 2-ton 25 h.p. chassis, and also a special model of this chassis with 9-ft. wheelbase, and forward dash and body designed to be useful for the carriage of mineral waters and similar commodities. Other exhibits will include model KV, which, is designed for 5-ton or 6-ton loads, and JH, which is a 3ietonner.
The new 30-cwt. to 40-cwt. chassis, which is built to the W.D. subsidy specification, will also be displayed. The general terms of the specification of this model are already well known, and need not be enumerated.
Latil
L.C. Rawlence and Co., Ltd., 39, Sackville Street, London, W.I. Stand 108 MHE LATIL exhibit at Olympia will be an interesting one. Five machines in all are to be-staged, of which one only will he a chassis, all the others being complete vehicles. The chassis is the 30-cwt. type BB, notable for its low loading line. The complete vehicles comprise an 18-seater one-manoperated bus and a motor coach, each mounted on the 30-cwt. s chassis; a 2-3-ton Latil-type VL3, equipped with a horsevan body capable of carrying two horses and attendants ; and a four-wheel-drive tractor lorry and trailer, with automatic coupling.
As all these chassis are new to the British market, and as each has many points of interest, brief reference to their specification will be of interest. The 30-cwt. model, which we have placed first, is of lesser interest if we are concerned with departures from the normal. It has a four-cylinder engine, single-plate clutch and four-speed gearbox, all in one unit. The springs are semi-elliptic, those on the rear being underslung in order to diminish the distance from ground to load level. The foot brake operates on a transmission drum, and the hand brake On drums on the rear wheels. The equipment includes electric starting and lighting disc wheels, and Michelin cord tyres 955 mm. by 135 mm. section.
The 2-3-tonner has front-wheel drive. Its engine is 105 ram. and 140 mm. bore and stroke, the clutch is a cone and the gearbox affords four stem& and reverse. The brake arrangement is the same as that of the 30-cwt. chassis, as also is the equipment, except that the tyres are of 155 mm. section. •
The four-wheel-drive tractor-trailer outfit is a most interesting exhibit, particularly in regard to the method of coupling the two units together. It. is equipped with the same powerunit as the 2-3-tonner, and has a five-speed gearbox behind its cone clutch. The tractor has pneumatic tyres of 955 mm. by 155 rem. section; the trailer is shod with solid band tyres.
Lancia.
Lancia and Co., 18, Berkeley Street, Piccadilly, London, W.1. Stand 22 MHE Lancia exhibit of five vehicles will, with the excep
tion of the one chassis, be all passenger machines, some of them of a most luxurious type. The chassis is the 35 h.p. Tetraiota type, which has a capacity for 2k-ton loads. It has a four-cylinder engine, end its transmission embodies a multiple-disc clutch, four-speed gearbox and spiral bevel drive. The v equipment is poeumatie, embodying six Michelin cabl of 895 mm. by 135 mm. section. All the
'
complete vehicles are mounted chassis of the same type. Exhibit. No. 2 is an 18-20-seater open coach de luxe, built by Bartle and Co., and incorporating the Bartle patent hood. It is all-weather equipped. and is painted aluminium, -with maroon antique leather upholstery and maroon wings and 'wheels. Exhibit No. 3 also includes a body by Bartle and Co. It is described as a Riviera-type semi-enclosed coach; there are three rows of Beats, those at the.rear are enclosed, the other two being open. There are four entrance doors at each side, and a collapsable canopy is provided for the exterior seats. This vehicle, too, is painted aluminium, with maroon wings and wheels, with maroon-coloured Bedford cord upholstery to the interior seats and antique leather to the exterior. The third chassis has a 20-21-seater front-entrance service omnibus body by Metcalfe, with a "pay-as-you-enter" door of the folding 4.ype covering the steps and manipulated by the driver. Frameless and balanced drop windows are fitted ; there is a special partition behind the driver, and the seats are all fitted with spring backs and cushions.
Exhibit No. 5 is a 20-seater all-weather saloon coadh by the Northern Counties Motor and Engineering Co. This has front and rear near-side entrances and a full-width partition behind the driver. It has frameless balanced drop windows, RaWlings patent window lifts, armchair seats, and a roof which incorporates a patent longitudinal sliding frame covered with duck twill.
The whole of the exhibits on this stand are painted unifoimly aluminium, with maroon upholstery,wings and wheels, and the effect should be extraordinarily good.
Leyland.
Leyland Motors, Ltd., Leviond,Lancs. Stand 99
THE LEYLAND exhibit will be a most comprehensive one, embodying no fewer than seven vehicles, one engine and two models, 'representative of all types of Leyland production. Most interest will naturally attach to the new 30-cwt. chassis, which will, appear fitted with a bus body and also equipped as a brewers' dray. The former has seats for 20 pas.sengers, and is a typical example of this class of vehicle, for which the Leyland Co. have acquired, justifiably, a high reputation. , The brewers' dray consists of an, open body with the usual stanchions and chains which one associates with this type of vehicle.
Those who are particularly interested in public-service vehicles will do well to take particular note of the Crosvilletype bus, which will be shown mounted on one of the forward-dash-type chassis. The bus is a single-decker, and is interesting on account of the arrangement of the seats, those in the front facing forward, those in the rear inwards, the two sets of seats being separated one from another by a transverse partition. There are two doors in addition to that provided for the driver; one of them gives entrance to the front portion, the other to the rear. There are to be a couple of Trojan parcelvans on the stand, each of them providing cargo space of 60 cubic ft., and being capable of conveying loads of 5 cwt. It may be as well to remind readers that this chassis is equipped with a special type of super-resilient solid tyre, which, together with the particularly flexible springing, is claimed to afford a suspension comparable with that of a similar vehicle on pneumatics.
The fire-fighting section of the Leyland Co.'s activities will his represented by a 500-gallon fire-engine of standard type, equipped, as is usual with all Leyland fire-engines, witl a Rees-Roturbo pump. Another representative of this depart meat will be the Leyland portable fire-pump, which embodies a small Rees-Roturbo pump driven by a V-twin engine, the whole being mounted upon a tubular steel frame and-weighing not more than 2i cwt. Equipped with a pair of pneumatic-tyred wheels and a suitable tow bar, it. is no more than a comfortable load for two men' or, alternatively, can be towed by a car up to speeds of 50 m.p.h."
The eighth exhibit will be an engine as fitted to the new 30cwt. chassis. This power unit is interesting on account of the advanced features of design, such as hemispherical cylinder heads and triple eccentric drive for the overhead camshaft, which are incorporated in its Construction. Unusual flexibility as well as fuel economy are claimed for the power unit.
The two models to be shown are an R.A.F. 4-tonner and a Leyland chassis fitted with a tipping body operated by Bromilow and Edwards gear.
L.V.L.
Light Vehicles, Ltd., Polivlett Street, Wolverhampton. Stand 124
ACAB, a van and a 20-seater motor coach are being'. exh'ibiteci byLight Vehicles, Ltd. All are mounted on this concern's 25-cwt. chassis, which, as-may be remembered, was only introduced at the close of last year. The vehicle is of
• interesting design, embodying a 20 h.p. Dorman engine, four" speed gearbox and final drive by overhead worm and wheel, the axle being fully floating and incorporating a -doublebanjo forging. The engine mild gearbox are separately
mounted in the frame, which is a substantial component built of rolled channel steel, and between clutch 'and gearbox a short, doubly jointed shaft intervenes. Both the brakes take effect on the rear wheels and are of the internal-expanding, four-shoe type, thus reducing the necessary width of the drum to a minimum. An,interesting feature of this vehicle, hearing in mind its rarity in connection with commercal chassis construction, is the employment of the Merles steering gear. . Another curious feature is the drive of the fan and water impeller. This is effected by means of a Vdeather belt, which derives its power Trom a. pulley on the engine shaft and transmits it to two others, one of which drives the pump and the other the fan.
Longframe.
Longirame Six-.Wheeler "Construction Co., " 58, Bradgade, Copenhagen, Denmark. Stand 55 /INF of the most ingenious six-wheeler constructions at the IL/show will be that exhibited by the Longframe Six-Wheeler Construction Co., of Denmark. Its special feature is the peculiar articulation of the two main portions of the chassis; the tractor and the trailer. The frame of the former is elongated, and actually carries the whole of the body itself, the rearmost pair of wheels supporting it through the medium of a special sub-frame, which is hinged at it front end to a point in line with the rear attachment of the back springs of the central axle. The rearmost axle is made to steer in conjunction with the front one, and this, as will he understood, considerably improves the manceuvring qualities of the vehicle as a whole. It is claimed that the springing is so designed that every one of the six wheels takes its proper share of the total load, whatever may be the relative position of those wheels. Alternatively, the vehicle may be designed so that the weight is distributed over the three axles in any desired proportion. It is claimed, too, that once these proportions have been determined and the vehicle constructed in accordance therewith, they are maintained, no matter what the conditions of loading may be.
Mann.
Mann's Patent Steam Celt and Wagon Co., Ltd., Pepper Road, Henslet, Leeds. Stand 43
THE MANN exhibit will be a 6-ton end-tipping wagon. The special feature of the Mann steamer is, of course, the provision of side:firing of the boiler. This enables the driver to act also as stoker, and eliminates the need for a second man. The bunker is 'placed immediately in front of the driver, and he is able to stoke up without having to turn round or even to look at his boiler. He can, therefore, continue to drive quite safely while carrying out this operation. Moreover, the side fire-door arrangement allows him to stand on the road at the side of the wagon and remove clinker from the fire when necessary with extreme ease and convenience. The endtipping gear which will be fitted on the Mann is engine-driven by chain and bevel gear, the final-drive mechanism being a sprocket eegagin,g with roller-protected pins on a special link which, as it is elevated by movement of the sprocket, lifts the front end of the wagon and tips it. An advantage which is claimed for this design is that there is no binding due to bending or distortion, such as may occur with a screwtipping gear.
Maudslay.
Maudslay Motor Co., Ltd., Parkside, Coventry. Stand 100
THE Maudslay exhibit comprises a 7-ton lorry with a cab and platform body, a 30-cwt. chassis, a 2-tormer equipped with a single-deck 25-seater pay-as-you-enter bus, and a passenger chassis suitable for double-deck or large single-deck buses, Of these four exhibits most interest will attach to the 30-cwt. and 2-ton machines, as they are new models. Both are alike as to their general specifications, the outstanding point of difference being that, whereas the 2-tonner is equipped, as standard, with solid-band tyres of 100 mm. section, the 30-cwt. is pneumatic equipped, having 36-in. by 6-in. tyres on the front and 38-in. by 7-in. on the rear.
In view of the novelty of these chassis a brief reference to their detail specification will be of interest. The engine is a 24.7 h.p., having four cylinders of 100 mm. and 130 mm. bore and stroke; it drives through a single plate disc clutch to a four-speed and reverse gearbox, which has been specially designed so as to reduce the distance between the bearings to the minimum possible, and this feature, combined with • the inclusion of unusually substantial shafts, ensures great rigidity and improves the quietness of running.
The rear axle is of the Maudslay well-known banjo type and has been drop-forged from a single billet. The final drive is by worm and worm wheel, the axle being, of course, of the fully floating type. The hand brake takes effect OR drums of large diameter mounted in the rear wheels ; the foot brake operates on a drum carried behind the gearbox.
Next in interest, no doubt, will be the special Maudslay passenger chassis. This embodies a 32 h.p engine, leather-lined cone clutch and four ,speed gearbox. The final drive in this case is also by worm and wheel, the axle being the Maudelay forged-steel double-banjo type. The braking arrangements and the transmission generally are on a par with those already described in connection with the new chassis, apparently the methods proving so satisfactory in the past as to justify their embodiment without alteration in the new chassis.
The 7-ton Mandslay was one of the first petrol chassis of this capacity to be made. It is of the forward:dash type, affording a free loading space behind the driver's seat of no less than 19 ft. 6 ins. Its engine develope 50 h.p. at normal speed and is a four-cylinder of 4 his, bore and 6 ins. stroke.
Minerva.
Minerva Motors, Ltd., Minerva House, Chenies Street, I.ondon, W.C.1. Stand 89
MINERVA exhibits include a six-wheel tractor lorry which possesses particular interest,inasmuch as the tractor portion is equipped with pneumatic tyres, those at the front being 440 mm. by 130 mm., and the rear 940 mm. by 130 mm.
twin. The trailer tyre equipment is 10-in. Giant solid c44 rubber. A plain trailer body will be fitted 19 ft. long and 6 ft.
wide. It has hinged sides. An interesting feature in this machine is the automatic coupling between the tractor and the trailer units. This mechanism allows of the two being coupled without the use of jacks and merely by backing the tractor under the trailer fore-end. Attachment is achieved after releasing a catch by reversing this movement. The same concern are also ring to exhibit a 2-ton lorry on 935 mm. by 135 mm. Michelin cord tyres and equipped with an open body with hinged sides.
Morris,.
Morris Motors, Ltd., Cowley, Oxon. Stand 111
THE Morris light van will be represented by two exhibits, one a plain box-type tradesman s van and the other a commercial traveller's vehicle, having two seats in front and a box in the rear. We may remind our readers that this commercial vehicle embodies the well-known 'Morris-Cowley chassis, and has a four-cylinder engine 69.5 mm. and 102 mm. bore and stroke, a three-speed gearbox and a worm-drive rear axle.
Orwell.
Bansomes, Sims and Jefferies, Ltd., Orwell Works, Ipswich.
Stand 38
RANSOMES' electric and steam vehicles are to be well represented by select examples at Olympia. Perhaps the most interesting is the 5-ton electric chassis, which is the premier exhibit. This is equipped with a 40 I.M.V. battery composed of 12 Ironclad Exide cells with a capacity of 387 amp.-hours, calculated on the 5-hour discharge rate. The controller is of the series-parallel drum type, and is located beneath the driver's seat._ There are two motors to the chassis, each driving its own rear road -wheel. The second exhibit will be an interesting combined platform and elevating truck. This is a machine which is very valuable as an adjunct. to any manufacturer's factory equipment. Loads of two tons can be carried and lifted by the mechanism which it embodies. This chassis also embodies an Ironclad Exide battery and twodriving motors, which, however, are bolted direct to the swivel axles. It is claimed that the control of the truck is very simple, so that it can be mastered by an unskilled labourer in a very short time. In addition to its use in and about a factory, it is also capable of road work and can traverse rough ground.
The 15-cwt. runabout crane was shown at. the last commercial yehicle show. It is constructed to travel, turn, hoist and derrick under its own power, and is actually able to turn on its own centre, thus possessing all the essential features of the most modern crane. The wheel system is an arranged that the crane can readily adapt itself to uneven ground, and, owing to the special system of construction, the load on any single wheel never exceeds 15 cwt. It is particularly suitable for such work as loading and unloading railway wagons and load vehicles, lifting heavy parts on to machine tools and so on.
The example of the Ransome steam wagon construction to be exhibited is a 6-tonrier overtype equipped with a three
way tipping body, hydraulically operated. An interesting feature orf the Ransome wagon is, of course, the patent boiler, which is built up of four plates only, screwed stays being entirely eliminated. The engine is of the compound type and the crankshaft is balanced by two discs instead of the usual flywheel. The frame is of pressed steel, tapering towards the ends, and the Steering gear of this wagon is of the Ackerman type with centre pivots. A 4-ton trailer suitable for use with this wagon is another exhibit, as also is a 4 nominal horse power light compound standard steam tractor, which is shod with solid rubber tyres.

Stand 46
THE makers of Pagefield motor vehicles, Walker Bros. !Wigan), Ltd., are exhibiting only an example of their ingenious system of refuse collection, which, introduced at Southport, is now being increasingly employed by municipal authorities all over the country. For the complete utilization of this system, there are required three horse-drawn collecting wagons, or containers, and one motor lorry. Each
container has a capacity of about 200 cubic ft.-----say, three tons-s-and is designed to have a low loading level. When one of the containers is full it is taken by the horses to the motor wagon, upon which it is hauled by special arrangements of eliding ramps and winch. The motor lorry then quickly removes the leaded container to the tip, empties it and returns to pick up another full one. Ne special pickingup stations are necessary, as the exchange can be made in any ordinary road without interfering with traffic. The system is really a combination of horse haulage and motor traction, each in its most economical form, and it is, moreover, cheap and highly efficient. At Southport an actual saving of is. 111d, per house cleared has resulted from the adoption of this system •

RENAULT, LTD., should have a very full stand of exhibits. At the time of goiag to press it is their intention to show no fewer than a dozen different vehicles. We shall have to content ourselves with a, brief enumeration of these, as more is not possible in the small space available, for the description.
Taking them in order of size, the smallest is the 8.3 h.p. 5-cwt. chassis, which will be shown as a boxvan and as a tradesman's van. The 13.9 lap: appears four times on the list of exhibits, one as a 10-cwt., the other three being 15-ewt. Special attention will no doubt he directed towards the fireengine, which is on the 10-cwt. machine. One of the 13.9 h.p. exhibits is a chassis only, mounted on Michelin pneumatic tyres; another is a boxvan and a third a tradesman's van, as in the case of the 8.3 lap. chassis. The 17.9 h.p. 30-cwt. chassis is to be shown with a 14seater char,it-barics body, and a larger model, with the same engine hut having a capacity of 2 tons 15 cwt., carries a 20-seater motor coach, Then there is the 24.8 lap. chassis, which also appears in two capacities. This is shown in chassis form, the smaller having a capacity of 3 tons and being designed to have the engine beneath the driving' seat, that is to say, it is of the forward-dash type; the other is for 3 tons. A tipping wagon is shown on the 5-ton 24.8 h.p. chassis, whilst the twelfth and largest exhibit will be the Renault 10-ton trailer and tractor. This also is equipped with a 24.8 h.p. engine, and the overall knell of this exhibit is 31 It,. 5 ins. It is interesting to note that out of the 12 only two, the 5-tonner and the 10-tenner, will be solid-tyre equipped. The others are all mounted on pneumatics.

Saurer Confmercial Vehicle Co., Ltd., .21, Augustus Street, London, N.W.I. Stand 25
NO doubt the most interesting of the Saurer exhibits will be, as hitherto, the three-way tipping body. This always attracts a considerable amount of attention wherever it is shown, and, as before, it, is intended to keep the, tipping gear more or less continuously in motion, the power for that puspose being provided electrically A Saurer polished chassis will he shown, exhibiting the special features of the design of this chassis, including the patent engine brake, the lubrication system, which embodies two pumps and is designed to ensure that on each stroke a smallmeasured quantity of fresh oil is introduced into the sump, the direct single reduction bevel gear final drive, the totally enclosed universal joints and the design of the rear wheels, which are dished so as to bring the twin tyres into more even contact with a cambered read surface. This show chassis will be equipped with pneumatic tyres, singles on the front and twins on the rear.
The chassis carrying the three-way tipper will be a 40 h.p. machine with a capaCity of 5 tons to 5L tons, Another.model of the same chassis will be shown as submitted for teat to the R.A.C. It may be remembered that the Club granted a certificate to this chassis, which showed that a recent performance indicated that its fuel efficiency was 50 per cent. above the best previous record. Th0 load then carried was tons, and' the 'average weight throughout the 1,006 miles was 10 tons 121 cwt. The consumption of motor spirit gave a ton-mileage figure of 104.66, a truly remarkable, result when it is considered that the total load was not very great. The fourth exhibit is a 32 h.p. 3-31-ton chassis, This will be fitted with a special aanitary dustcart chaesis, which will also be shown in operator'.
Scammell.
ScammelI Lorries, Ltd., Fashion Street, Spitalfields, London, E .1. Stand 36
SCAMMELLS are showing three of their well-known sixwheelers, each of the exhibits being representative of one of the must effective uses to which these capacious vehicles can he put, Exhibit No. 1 is a 2,000-gallon petrol tank wagonwhich has been made for Shell-Mex, Ltd. It is part of an order for 14 such vehicles, which will bring the Shell fleet of Seammells up to 22. The second exhibit will be a 12-ton three-way tipping wagon, with a body having a capacity of 12 cubic yds. This also is a repeat order, and is destined for Poole, Dorset, for employment by Southern Roadways Ltd., who have had two such vehicles in use now for a considerable time. The third machine is also a 12-tonner, and is a general-purpose vehicle with d4opped frame.
The outstanding features of Seammell lorries are, the arrangement of the springing and the use of chains for the final drive on the tractor portion. The makers claim that a special feature of this chassis is its relatively light weight, also the large tyres which are fitted. The 12-tonner only tips the scale at 4 tons 17 cwt.
Those machines exhibited embody several improvements, Erich as the use of bronze shells, lined with white-metal, in place of the die-cast bearings formerly employed in the engine. Aluminium pistons of special design are now standardized, and are constructed so as to enable a higher compression pressure to be used, giving reduced fuel consumption as well as diminished vibration.
The dren-frame general-purpose body has several interesting features, and is capable of being converted in a few minutes from a plain flat platform body with chock rail into a body with hinged and removable sides 2 ft. high secure& to steel stanchions 4 it. high which serve to steady any portion of the load which comes above the top of the sides.
S.P.A.
Vandys, Ltd., 27a, Pembridge Villas, Notting • Hill Gate, London, .W.11. . Stand 95
S.P.A. commercial vehicles are made in two types, known as the 25-CA and 25-CB. The former has a 25-30 11.p. fourcylinder engine of 100 mm. bore and 140 mm. stroke; its capacity is 50 cwt. and it is equipped with 895 mm. by 135 mm. pnennmatic tyres—singles at the front and twins at the rear. The other has a 20 h.p. four-cylinder engine of 85 mm. bore by 120 mm. stroke; its capacity is 49 cwt.' and its tyre equipment is the same as in the model 25-CA. Both these chassis are alike as to their general specifications. The engine and gearbox are mounted together as a unit, with right-hand control; the transmission is fully enclosed, the propeller shaft being encased in a long tubular torque and thrust member, but the brakes are arranged to take effect, one on a. drum behind the gearbox, the other on drums in the rear wheels. The gearbox provides four speeds forward and reverse and the rear axle is of the full-floating type, the 'final transmission being by bevels and internal gears following S.P.A. patented construction.
At the Show one of the 50-cwt. chassis will be exhibited as such,and also as an 18-20-seater saloon coach. The smaller model will be shown as an 18-20-seater coach and also equipped with a 20-seater bus body.
Sentinel.
Sentinel Waggon Works (1920), Ltd., Shrewsbury. Stand 119 MHE Sentinel exhibit includes no fewer than five vehicles, all of them being new models, inasmuch as every chassis shown embodies the new Super-Sentinel patent engine, which incorporates in ite construction, amongst other novel features, a differential, which is ,built up with the crankshaft. This is a most interesting feature; the gear consists of a number of shafts and spur wheels disposed in and around the crankpins and webs so as to give true differential action. An imnortant point in its construction is the means whereby the differential is prevented from functioning until a difference of 10 per cent. or 15 per cent of effort as between the two chain sprockets is felt.. It is claimed that this arrangement abolishes 90 per cent, of the tendency to skid. A fullsize working model of this differential gear will be on the stand, and is well worthy of close investigation.
The eallIbtts include a Super-Sentinel Eaton chassis equipPed witi. a miller's tilt-van body a chassis only, of the same type, and another one equipped with a three-way tipping 046 body. There is to be a Super-Sentinel six-wheeler on the stand fitted with a high-sided body, and also one of the ingenious and novel tractors, one of which was described in The COMmerdal Motor a few weeks ago.

ALL the Star chassis, which are designed for loads of 20 to 25 cwt., 30 to 40 cwt., and 50 to 60 cwt., embody four-cylinder engines of 90 mm. bore, that on the smallest chassis having 120 mm. stroke, the stroke on the others being 150 mm. At Olympia there will be an example of each chassis, and in addition one of the 30-40-cwt. type, equipped with a tipping body, r
The general specifications of these chassis are alike, eMbodying engines as already stated, four-speed gearboxes and worm-driven rear axles. The 20-25 cwt. is usually equipped with pneumatic tyres of 34-in. by 5-in. section and the others are shod with solids of 80 rem. and 100 mm. respectively for rims of 720 mm. diameter.
Stevens' Petrol-electric:
Stevens' Petrol-Electric Vehicles, Ltd., 68, Victoria Street, London, S.W.1. Stand 12 TEVENS' petrol-electric vehicles will be fully represented by two examples, one of each of the two, sizes in which that chassis is made. The 2-2L-tonner will he shown as a chassis only, and the 341-tonner as an ordinary plaint lorry v-ith driver's cab. The former embodies a four-cylinder engine of 105 mm. bore and 150 mm. stroke, and the latter has a similar type power unit of 115 mm. bore and 150 mm. stroke. The feature of these chassis is, of course, the petrol-electric transmission. The dynamo is flexibly coupled direct to the engine, and behind it and in line with it, mounted on the same subframe, is the motor ; behind the motor is a short shaft which carries at its front end the transmission-brake drum, and at its rear is coupled to the propeller shaft proper by means of a universal joirbt. The last-name& component, is totally enclosed in a spherical housing, which is, as a niatter of fact, the front end of the propeller-shaft casting, which serves as the torque and radius rod. This spherical housing takes a bearing in a substantial casting which extends across the frame to which it is bolted at, both sides. The final drive in these chassis is by worm arid wheel and the braking is arranged to take effect on the transmission drum and on drums on the rear wheels.
Straker-Squire.
Straker-Squire, Ltd., Angel Road, Edmonton, London, N.I8.
THE Straker-Squire exhibit will include a chassis, two buzes and a tipping wagon. The chassis exhibit, will be of the " A " type, which, as is now well known, is designed so that it may be readily adapted for use in connection with loads of front 3 to 5 tons. It, will bear close investigation and has many distinguishing and meritorious features. The engine is of the overhead-valve type, the cylinders and the top half of the crankcase being made as one casting. The crankshaft, which is 3 ins, in diameter in the main, runs on a couple a ball bearings. The gearbox provides four speeds forward and reverse and the final-drive mechanism is an overhead worm. An interesting feature is the design of the universal joints on the carden shaft, these being fitted with spring-backed stuffing-boxes, so as to ensure adequate and thorough lubrication.
The " A "-type Straker-Squire is of what is commonly referred to as the forward-dash construction, and an interesting point in this chem.* which was originally designed in this manner, is the neat arrangement of the steering gear. Attention, too, should be directed to the method of attaching the springs to the chassis, and, in point of fact, it will be one of the most interesting engineering exhibits at the show.
One of the complete vehicles is to be a London-type bus, the others are as has been stated.
Ta.sker.
William Tasker and Sons, Ltd. • Waterloo Ironworks, Andover. Stand 129
THE Task3r exhibit -will include several new models, for, in addition to old friends like the "Little Giant " patent chain-driven steam tractor and the Tasker15-ton over-type wagon, there are also a new steam wagon with a capacity of nix tons, and a tandem steam-roller.
The 6-ton steam Wagon, like the 5-ton nor,is of the overtype, and has a compound engine that embodies a three-speed gear and Ackerman steering.
The tandem roller has been specially designed for rolling asphalt tar macadam and similar road earpetings. In designing this machine, the makers have followed the principle embodied in the "Little Giant" tractor, so that it may be taken that it is chain-driven and well sprung. The weight distribution over the rollers is such that each presses upon the ground with the same intensity.
Thornycroft.
John I. Thornycrolt and Co., Ltd., Brisingstoke. Stand 97
THORNYCROFTS will stage six exhibits, and it may be said that these are collectively representative of this company's activities in connection with commercial-vehicle construction.
The -6-ton brewers' lorry is mounted on the largest chassis which Thornyerofts make. It is one of their latest introductions, being of the forward-dash type and equipped with the new 50 h.p. engine, which will be on view at Olympia for the first time. The body has hinged sides, with easily removable stanchions, and, we understand, is a repeat order for the firm of brewers for whom it. is made.
The tank wagon has a capacity of 1,200 gallons and is
D-shaped. It is designed for the transport of petroleum spirit in hulk. 'This particular vehicle is fitted with a 40 h.p. engine, as the conditions under which it will be called upon to work do not necessitate the fitting of the 50 h.p. unit, which, however, may be incorporated in this type of vehicle if desired.
A particularly interesting exhibit will be the Thornycroft six-wheeler, which is designed for a load of not more than four tone. It is built to comply with overseas conditions, where axle weights are restricted, and both chassis and trailer attachments are equipped with pneumatic tyres. Thornycrofts now make three different model six-wheelers for loads up to 12 tons.
Amongst Passenger vehicles, Thornycroftproductions stand high, and it is not surprising that, out of six exhibits three are of this class. One of them is a 25-seat single-deck bus on a 30 h.p. chassis, equipped with pneumatic tyres; the second is a 50 li.p. double-deck omnibus of London type with forward dash. It is particularly suitable for passenger servite wherever traffic requirements warrant the running of large-capacity vehicles. The third machine is a motor coach de luxe, which is aptly named the "Patrician." Although mounted on the 30 hap. long chassis, the seating arrangements only provide for 18 passengers, with room for two more on folding seats, conditions Vieth make for improved comfort for those who have to ride in this type of vehicle.
Traffic.
North Western Motors, Ltd., 35, Norton Street, Liverpool.
Stand 120
TRE new model Traffic truck is to be shown in chassis form and also equipped with a flat platform body. The outstanding features of this chassis, which has been entirely revised since we last saw its are its rear axle, its Continental Red Seal engine and its Covert gearbox. The first-named is a Russel and is of the internal-gear type. In this axle the load is carried on a, 2,3-in. solid round chrome nickel-steel bar. The gear and transmission areseparately mounted and supported on the same axle, and the final drive is by internal pinions and gears, which are mounted on drums in the rear wheels. The engine, which is of 31 ins. and 5 ins. bore and stroke, is three-point suspended in( the frame, and it tranenaits through a multiple-diac clutch to the Covert three
speed-and-reverse gearbox. Behind the gearbox the drive is by means of a two-piece propeller shaft, and the 'brake arrangement embodies internal-expanding and external-contracting shoes on the rear-wheel drums. The new features which distinguish the 1924 Traffic from its predecessors are the new type frame, the modified radiator, the design of the running hoards and the valances, the locatitan of the steering gear and hand brake, which are now at the right-hand side of the driver, the provision of a radiator buffer and the embodiment of a hinged radiator.
Tilling-Stevens.
Tilling,Stevens Motors, Ltd„ Maidstone Stand 96 MHE Tilling-Stevens exhibit includes a double-deck London1. type bus, a chassis of the forward-dash type and a Bantam fire pump. The chassis is, of course, of the petrolelectric type in which the engine drives a dynamo generating current, which is used by an electric motor in transmitting the power through the medium of an overhead worm wheel. Both the chassis which is exhibited and that upon whieh the double-deck bus is mounted embody 40 h.p. engines having four cylinders of 44 ins, bore and 4 ins. stroke, the load capacity being 5 tons.

Unic.
link Motors, Ltd., 18, Brewer Street, Buckingham Palace
Road, London, S.W.!. Stand 115 TTNIC MOTORS will be exhibiting a standard cab chassis and a complete cab, a one-ton chassis, a 30-cwt. chassis and a motor coach. The cab will, of course, be the wellknown Unic which has been so long recognized as one of the best of those constructed to Scotland Yard requirements. The one-ton chassis has a four-cylinder 75 mm. and 120 rem. engine end a four-speed gearbox with spiral-bevel final drive. It is equipped with 880 mm. by 120 mm. pneumatic tyres, singles on both front and rear wheels. The 30-cwt. chassis has an engine of 80 mm. and 130 mm. bore and stroke ; like the one-tonner, it has a. four-speed gearbox and spiral-bevel c47
rear axle and its tyre equipment is six 820 mm. by 120 mm. pneumatics, one on each front wheel ; two on each rear wheel.
A motor coach is mounted on the 30-cwt. chassis, as briefly outlined above. It is of standard censtruetion, embodying four rows of seats, of which three hold four persons each, two more being able to sit by the side of the driver on the front seat. There are doors on the near side only, and the running boards are covered with aluminium and metal-edged, suitable valances being fitted between the edges of the frame and the running boards. The equipment includes a C.A.V. electric lighting set, Cape-cart hood and side curtains and a glass windscreen fitted with side wings.
Vulcan.
Vulcan Motor and Engineering Co. (1906), Ltd., Crossens, Southport. Stand 116
BBING UNABLE, on the space available on the stand at Olympia, to stage sufficient vehicles representative of all their products, the Vulcan Motor Co. have decided to concentrate upon one type of cheesis, showing it equipped with various types of bodies. There will be four such exhibits, including a 26-passenger omnibus, a three-way tipping wagon, a timber lorry and a 20-seater motor coach, the chassis in every ease being the Vulcan standard 2-tonner.
The omnibus to be seen will be an attractive single-decker saloon, with entrance doors for passengers at both front and rear on the near side, in addition to another on the off side for the driver. It is designed so that it may be either one-man-controlled or worked in conjunction with a conductor. In the former case the driver controls the entrance door at the front by a conveniently situated lever; the action of closing the front door automatically folds the lower step, making it possible for anyone to hoard the vehicle whilst it is in motion. A novel refinement, worthy of special notice, is the prevision of stop-lights, which illuminate the steps during such time as the door is opened for passengers to mount on, or alight from, the bus. Closing the door switches off this light. The interior is divided by a partition with a sliding door. The seats in the front portion are of the semi-bucket type, arranged in pairs to face forward; those at the rear are arranged round the sides.
The three-way tipping wagon on the stand will be hydraulically operated, twin rams being used, which are cap-able of tipping the body to the rear, or to either side, in 25 secs. A feature of this vehicle is the design of the driver's cab, which is fully enclosed; each door has frameless polished glass windows, which can be adjusted to any height by
means of straps.
The timber lorry is designed and equipped especially to afford convenience when transporting timber in long lengths, provision being made for the support of such a load at four points—namely, at the front and rear of the cab (clear of the. roof), at the centre of the lorry, by means of a removable bolster, and at the end, by the tailboard. To accentmodate the load the roof of the cab has a considerable downward slope from front to rear. The front pillars are carried well above the roof and support a crossbar. The back of thecab is similarly designed, and both crossbars are sufficiently high to ensure that the load will be lifted clear of the roof.
The char-a-bancs is a 20-seater of the transverse-seating type. There are five rows of seats with a door to each row except the fourth, access to which is obtained by lifting a portion of the preceding row.

don, S.W.1. Stand 19 NATALKER VEHIOLE8, LTD., makers, of electric chassis, vv will be showing a standard 2-ton chassis equipped with their well-known balanced drive, and, in addition, in order to demonstrate clearly the action of this ingenious mechanism, a separate back axle will be shown operating very slowly, so that the movement of the gears may be observed through the glass outer disc with which the wheels of this exhibition axle are to be specially fitted. This chassis cannot fail to be of interest, as the whole of the power mechanism, including the driving motor, is enclosed in the rear-axle easing.
W. and G.
W. and G. du Cros, Ltd., 177, The Vale, Acton, London, W.3. Stand 83
ASPECIAL 2-ton chassis, with an extended wheelbase of 15 ft., will be shown by W. and G. du Gros. This, we understand, has been specially designed arid prepared for exhibition for the first time at Olympia. It is equipped with Dunlop pneumatic tyres, singles on the front and twins on the rear; and will be shown in one case as a chassis only and in the other equipped with solid tyres and carrying a 20-seater de luxe single-bus body made hy James Bartle and Co., Ltd. The third exhibit is to be a 2i-ten W. and G. standard model, upon which will be mounted two 25-cwt Makrob separate compartment gravity tipping bodies. The general specification of the W. and G. chassis is by now fairly well known. Both models are alike in the, essential details, embodying a four-cylinder en bloc engine of 31 ins. and 5i ins, bore and stroke and a cone clutch lined With rerodo fabric. The gearbox on the 2-tonner affords three forward 'speeds and reverse, that on the 2i-tonner giving four speeds. The final drive of both chassis is by overhead worm and wheel, the difference between the two being in regard to the ratio, -which in the one is 61 to 1 and in the other 8 to 1. The axle
is of the fully floating typeBoth brakes take effect in drums on the rear wheels.
The Makrob gravity type tipping bodies are also fairly well known. They incorporate V-shaped steel receptacles which are designed to be tipped independently of one another and to either side of the lorry.
Westcar.
Strode Engineering Works, Herne, Kent. Stand 78
A NEW 10-cwt. delivery van will be found on this stand. It is all-British and has many novel and excellent features. Great economy of running costs is claimed for it, the petrol consumption being no more than a gallon per 35 miles, the oil consumption being low and the pneumatic tyres averaging 7,000 miles to a set. The power unit is a four-cylindered monobloc, with valves all on one side, the engine bore being 69 mm, and the pistoa stroke being 100 mm. The power is taken through a gearbox providing three forward speeds and reverse, and thence by propeller shaft to. the rear axle. The chassis is mounted on long springs and on Sankey steel wheels equipped with cord tyres. On a wheelbase of 9 ft., a platform area of 17 sq. ft. is afforded.
An interesting feature is the Moles patent steering gear.

THE exhibit, of this well-known concern will be of more than usual interest. The following vehicles will be en view :—An Overland 1-ton truck, an Overland traveller's brougham, a coupe-brougham, a 10--ewt. Overland van for rapid delivery work, and a C4arford 30-cwt. truck. The 1-tonner is equipped with a starting motor and dynamo, and the •chassis follows orthodox practice. A feature of interest is the Russel double-reduction internal-gear drive on the back axle. The chassis weight is only 14 cwt., and the equipment is remarkably complete.
The coispe-brougham provides very comfortable seating accommodation for two people in the driver's compartment, and at the back there is a large enclosed box for carrying samples. The chassis is built on touring-car lines.
The 10-cwt. delivery van mounted on the orthodoxOverland chassis is provided with rear doors opening to the full -width of the van, and is generously equipped-. This vehicle is particularly suitable for tradesmen delivering light loads at. high speeds.
The Garford 10-cwt. truck is now, well known in this country. It embodies a four-cylinder engine, three-speed gearbox and worm drive. The chassis te be shown will be equipped with giant pneumatie tyres.
• Yellow Cab.
Yellow Cab Manufacturing Co., of England, Ltd., 173-175, Great Portland Street, London, W.I. Stand 25.
THE Yellow cab Manufacturing Co. are newcomers to this country and to the show. It follows, therefore, that all the vehicles to be seen on their stand are New, so far as we e
are concerned. They will be showing an -express-delivery chassis, a complete taxicab, built to comply with Scotland Yard regulations, and a cab chassis..
The express chassis is a typical American production of this type, embodying a four-cylinder engine, four-speed gearbox, -multiple-disc clutch and bevel-driven rear axle; it is equipped with steel disc wheels, and, of course, runs on _pneumatic tyres. The cab chassis embodies a 3-in. four cylinder engine with unit-mounted clutch and gearbox. The brake equipment includes a band brake on the transm:ssion and a pair of bands on drums on the rear wheels, the former hand-operated and the latter controlled by pedal.
A special feature is made of the suspension: the semielliptic springs are not attached to the chassis by shackles, but are mounted at each end in rubber buffers. The changespeed-and brake levers are centrally mounted, and the wheels, like those of the express chassis, are disc.
