Platform Lorry. 51 ion Chassis.
STAND No. 31.
British Agents Societe Des Automobiles Brasier, 7742, High Street, Maryleboite, London, Ar0 FINE vehicles are shown on the stand occupied by this well-known kren,c.h company. One is a five ton chassis fitted with a platforni body, and the other a 34, ton, chassis with a tilt van body. Michelin steel disc wheels and pnenaniatic tyres, single at the front and twin at the rear. Both chassis are very similar in design, varyingonly in the matter of springing, the strength of the axles and in the final drive gearing.
The power , unit is a four-cylindetted monobloc, L-headed, with the valves at the near side. The bore and sttroke are 100 min. and 150 nun. The speed of the engine is controlled by a. sealed centrifugal type governor driven from the cam
shaft and carburation is attended to by a Zenith carburetter of horizontal pattern. Lubrication is by pump to the camshaft bearings and from thence to troughs under the big ends. The cooling water is circulated by a centrifugal pump, the radiator being of the castaluminium header and bottom tank type. Cooling is assisted by a fan, supported in a bracket bolted to the rear of the radiator and passing across from one side -bracket to the other. On. the smaller model an. air pump is friction driven from the periphery of the flywheel.
In the flywheel is fitted a cone clutch, faced with thermoid. The four-speed gearbox is in one with the countershaft, the whole unit being supported at three points. From this the final drive is by open roller chains to the rear wheels.
In order to enable the vehicle to drive on slippery surfaces, or when one chain has broken, a, differential lock is provided, and this can be operatedfrom the driver's seat. The foot brake operates on drums on the differential shafts, whilst the hand brake has internaheipaaiding shoes in the rear wheel drums. These brakea are of simple. character.
The frame is of deep section, tapered to front and rear anti insw opt at the front end to give a large lock. On the back axle there is a heavy sprag, built up from channel steel members. The shackle pins are all lubricated from cups fitted with spring lids. To assist in loading or unloading the platform lorry, three rollers are partiallysunk into the platform. These stretch the whole width of the latter.
