THIS stand contains what is probably the most comprehensive range of vehicles at Olympia, for the requirements of all types of operators are met in an array of machines ranging front a 15-cwt. van at £195 to a doubledeck bus chassis costing £1,075. Amongst the vehicles shown is the new 5-ton Courier chassis, which, with a wheelbase of 13 ft. 6 ins., and a track of 5 ft. 10 ins., has forward control and is powered by a four-cylindered engine built very much upon the lines of the well-blown Dictator unit. Actually the forward part of the six-cylindered and four-cylindered engines are almost identical in shape and general layout, but the former has, of course, two extra cylinders.
Like the Dictator engine, the fourcylindered unit incorporates the patented -mounting arrangement which allows the -whole power-unit to be wheeled out on the front axle, after removing a relatively small number of attachment bolts and disconnecting such items as the fuel pipes, driving controls, etc. Each of the cylinders has a bore of 110 mm., which, combined with a piston stroke of 135 mm., produces the total swept volume of 6,132 c.c. At 2,500 r.p.m. 85 b.h.p. is developed, whilst at the lower end of the power curve the torque figure is distinctly good, considering the size of the engine. What is known as the " high-eamshaft " principle is also incorporated, the monobloc carrying the camshaft in an oil bath at the top of the casting, but immediately below the head joint (and alongside the cylinder
D38 barrels) ; the reciprocating motion is transmitted from the cams to the valves by rockers.
In this 5-ton freight chassis the clutch is of the single-plate, dry type carried inside the bell-housing which connects the engine and the gearbox. This lastnamed component provides four forward speeds and is connected to an overhead worm-driven rear axle by means of a divided propeller shaft.
In the -double-decker chassis the sixcylindered Dictator engine is, of course, used and the transmission line has been offset in order to bring the axle pot under the near-side seat in the body, thereby allowing a clear gangway down the centre of the vehicle. An important feature concerns the design of the clutch, which has two plates instead of one in
order to bring the pressure on the one,
tion surfaces down to as low a figure as possible.
Amongst the smaller vehicles the 15-ewt. van is bound to attract a good deal of attention among tradesmen, etc., for, completely equipped with a grouped
chassis lubrication system, an electric lighting and starting set, and a powerdriven tyre pump, the price is but £195. Another popular vehicle is a 1-ton baker's van, costing £245.
Popularly known as "the middleweight champion," a 30-cwt. lorry, which, by the way, has recently been brought thoroughly up to date, is shown, -and is moderately priced at £230. The engine develops over 45 b.h.p. and, with a four-speed gearbox, provides a good all-round performance ; it is claimed that with a full load the vehicle can cagily climb gradients of 1 in 21-.
Shown for the first time is the 2-ton Economy lorry costing £263. This entirely new chassis has been expressly designed and built for 2-ton loads of fairly large bulk.
Of rather a different type is a 50-cwt, bulk load carrier with a special body. The chassis is of the six-wheeled, trailing-axle type, the bogie axles being capable of full articulation, although only the leading axle is driven.
Efforts have been made in producing an ambulance at £440, to meet modern conditions, in which maximum comfort, smooth and speedy running are outstanding features. The vehicle exhibited. accommodates two stretcher cases aad Jive or six sitting cases. Low-pressure tyres and hydraulic shock absorbers on all wheels are points which contribute to the comfort factor. The range on this stand is completed by an International taxicab costing £325.—MorrisCommercial Cars, Ltd., Soho, Birmingham.
