STAND No. 45.
British agents: Da Dion.Bouton, Ltd., 10, Great Marlborough Street, London. W. 1.
0 F the several examples of French commercial-vehicle productions at the Show, probably the best-known to our readers is the be Dion-Routom Three examples of the company's manufacture are shown on the stand of the British company, De Dion-Houton, Ltd., of 10, Great Marlborough Street, London, W. 1. Two of these are the 25 h.p. 3e ton model F.R. chassis, the third exhibit being the combined sweeping and watering machine.
Dealing with the lorry., chassis first, This possesses a four-celinder engine with a bore and stroke of 100 ram. and 140 mm. respectively. Its cylinders are cast in pairs with the valves on the near side. The. tappet guides are held clown in pairs by bridge pieces, and the exposed portions of the valve-operating mechanism are enclosed by pressed-steel covers, each being held in position by a spring locking device. Forced lubrication by rotary gear pump is employed for the main and big mid bearings, the small ends and pistons being lubricated by splash. The radiator is of the-tubular type, the tubes being formed: lute a circle, in the hollow centre of which is situated the fan. The small water tank is positioned at the top. The engine is supported at three points • at the rear on a stout, dipped cross-mener, and at the front in the centre of a similar pressedsteel channel cross-member. A large flywheel contains the clutch consisting of a steel disc on the gearbox shaft. The drive is taken through a non-flexible coupling to a four-speed-and-reverse gearbox, the latter also being three-point suspended. The change-speed gear is of the double countershaft type.
736 The footbrake shaft is carried right through the gearbox and its front end has a neat form of adjustment. The footbrake drum is situated directly behind the gearbox, and its shoes are of the internal-expanding type. The rear axle proper is a 4 in. diameter steel tube, and it carries the main axle castings which hold the rear wheel stub axles and the driving pinion for the internal gear. The hand brake operates on the outsides of the internal gear rings through the medium of external-contracting bands. One of the chassis of this type shown is fitted with 36 in. by 5 in. single tyres on the front wheels and twin solids of the same size on the rear wheels, whilst the second Chassis is fitted with 955 ram. by 155 mm. Michelin pneumatic tyres. The combined sweeping and watering machine exhibited should not escape attention. The water tank of this vehicle is made of sheet iron, and it has a capacity of 3,600 litres. On the top of the tank ie an orifice forming a chimney through which the reservoir can be filled when the city possesses a water distributing system under pressure. This orifice is hermetically closed by means of a cover, and a leather joint with an interior filter to stop all impurities from penetrating to the interior of the tank. The water filler can be dismounted and detached, thus leaving a large manhole —19 ins. by 16 ins.—in order that the interior of the reservoir can be properly cleaned.
The water spraying apparatus is composed of two perforated spouts situated in front of the steering wheel, and through these spouts about 50 gallons of water can be distributed per minute over a road width of 30 ft. To regulate the width of the. spray of water, the main spouts contain half-circular shutters that are governed from the driver's seat. The centrifugal pump, worked by the engine, forces the water at a suitable pressure through the distributing spouts; this pump can be disengaged by means of a lover actuated by heed.. The broom is composed of a central axle with flanges at each extremity. The broom mechanism operates as follows :The shaft of the reducing gear on the differential carries a coupling clutch which works, at will, a shaft parallel with the differential shaft, at the extremity of which is a coupled cone enclosed in a ease fixed to a short axle near the differential. The coupled cone communicates the movement to a cardan shaft
practically with the broom, and, in turn, t is drives an adjustable chain.
The total weight of the watering and sweeping vehicle, empty, and ready for the road, is 4 tons.
