CERTAINLY the most striking exhibit staged QR this stand is the. model 802 six-wheeled double-deck kis with covered top and with a total seatibg capacity of 68. The body is wellproportioned and has a low rear . entrance at the same height as that of the Associated Daimler N.S.-type bus. The seats have spring hacks and are Well cushioned. The lower saloon has

30 seats, whilst the upper has 38. The • whole of the body framing is in lightweight metal, all the members subjected to stress consisting of hollowsection Duralnmin. The bodywork is by Short Brothers and a patent has been applied for in connection with this form of coastruction. • Aluminium and Duralumin are also used for the exterior panels, the floors, roof and fittings. So far as the chassis is concerned this has been fully dealt with in the columns of this journal ; it is of a now design embodying many patent features, especially as regards the arrangement and springing of the bogie axles. It will be remembered that the system is such that the arrangement includes a differential taking effect between the two axles.

The power unit employed is a sixcylindered sleeve-valved engine of Daimler make developing a maximum

b.h.p. of 120. The -vehicle is equipped with Westinghouse air-operated brakes on all wheels and pneumatic tyres 6 ins. by S ins.

In another exhibit, utilizing the model 423 chassis, the body is again by Short Brothers, but in this case is a 34-seater saloon bus. Aluminium is used extensively for the panels, roof ends, window panes and interior fit

tings. The entranca is at the rear and Is equipped with .sliding doors and the seats are of the semi-bucket type ; Riiholeum is used as the. floor covering.

The model 423 chassis is entirely new and represents a great advance in weight reduction by the extensive employment of high-tensile aluminium alloys. It is equipped with a sixeylindered Daimler engine of smaller horse-power than that employed on the six-wheeler. In this case thc maximum b.h.p. is 70. .The brakes also arc operated in a different manner, in this Case through a Dewandre vacuum servo; another feature of the chassis is one-shot lubricaticn.

The clutch is of the single-plate pattern and is readily removable from the chassis as a whole. The four-speed gearbox is mounted separately from the engine and the box itself is made from high-tensile Omni/limn alloy. A similar material is employed for the wheels, which are of the detachable disc type, the material being thick at the hub and tapering towards the rim.

Reverting to the brakes, the leads are chiefly of the steel ribbon type mid as straight as possible. A single-poin:. adjuStment is provided outside the :frame and the four brakes may be 'taken up" simultaneously. Heat treated alum'aium is freely used in the front-wheel brake construction, also for the shoes of the emergency or parking brake.

This chassis has forward control, but the bare chassis of the model 424 is exhibited, and in this the driver is seated in the orthodox position. In other respects the chassis is the same as that just described.

So far as the goods type is concerned the 31-ton model 418 chassis is on view. This is also a new one, capable of maintaining good average speeds and having an ample reserve of power for hill-climbing. It is equipped with a 35-40 h.p. Associated Daimler four-eylindered engine of the poppetvalve pattern, a cone clutch, separate four-speed gearbox and final drive by overhead worm gearing. Pneumatic .tyres, 13 ins. by 7 ins., are fitted on the chassis shown,

Associated Daimler.
