Buick : 15-cwt. Chassis. 15-cwt. Van. Traveller's Brougham. G.M.C. :-30-cwt. Chassis. 14 and 28-seater Coaches 18-seater Bus,

STAND No.104.

AREMARKABLY wide range of vehicles is available for inspection on this stand, comprising the well-known Buick and G.M.C. chassis. The Buick is represented by a 15-cwt. chassis, a 15-cwt. van, and a private brougham mounted on the same club-structure. The G.M.C. is shown withea 26-seater saloon body mounted on the 2I-3-ton chassis. There is also a 14-seater de luxe and an 18-seater enclosed bus, both these being mounted on the 30-cwt. G.M.C. chassis. Finally, there is a. long-wheelbase G.M.C. passenger vehicle shown in bare chassis form, which is of the30,-cwt. type, but is fitted with a frame similar to that employed on the 24-3-tonner.

In order to enable one to examinethe engine and gearbox components, those of the 30-cwt. and 21.-3-ton G.M.O. are shown mounted separately_ort stands, and make an attractive exhibit. The design is very similar in each case, but a feature of the larger power unit, which is entirely novel, and should not be missed, is that two speeds are provided for the gearbox layshaft. This meens that, in addition to the direct drive on top, two sets of three-speed ratios can be used, giving seven alternative gear reductions in all. The scheme can be followed out on the 26-seater saloon, where it will be seen that two gear levers are provided ; one of , these has only two alternative positions, and controls the speed at which the layshaft rotates. The other gives a direct-type drive, and the three alternative indirect drives in the usual way. This feature is extremely useful in cases where a bus route involves long stretches of fairly ,level 'going followed by some really hilly country. Instead of having to provide an exceptionally large engine or a. gear which is too low for the level stretches, the seven-speed box . allows for all contingencies, and enables the vehicle to be driven under the best possible conditions. Incidentally, it should be mentioned that, as in the case of the other G.M.C. passenger vehicles shown, this 26-seater has a fine appearance. Access to the seats is oh tamed through a wide door at the near side of the driver's compartment, from which a gangway of adequate width runs throughout the length ,of the vehicle. Large glass windows are provided at each side and at the back; and above these is a series of ventilators.

All the Buick vehicles shown are fitted with the new four-wheel braking system; drums are provided on all four wheels, surrounded by contracting bands simultaneously operated by the pedal. The !overage exerted on the front and rear brakes can be adjusted to give the beet resuits for any given ease. The bare chassis shown enables one to follow out this braking system in its entirety. The hand . lever is independently connected to expanding shoe brakes.

The Buick traveller's brougham is an extremely smart turnout, the driver's 'compartment being totally enclosed, and ample space is provided at the back for the carriage of goods. The vadbody is also very neatly designed, and is finished in black and dark red.
