Wm. Allchin, Ltd.
Petrol and Steam Exhibits.
This well-known company show one of their standard 5-ton steam wagons, fitted with brewers' high-sided body, to the order of Page and Overton, Ltd., of Croydon. It is of interest to note that this vehicle is the third built for this company. It will be found on Stand No. 150, Row X.
The wagon shown is a fine example of the best workmanship. It has a locotype boiler, upon which the -Whole engine is mounted. The latter has high and low pressure cylinders, but an auxiliary valve allows for the admission of high-pressure steam to the low-pressure cylinder when extra power is required. The well-known Stephenson link-motion is adopted.
Two speeds are allowed by the gearing, and the final drive is by roller chain to the oiltight differential cage on the rear axle. Each rear wheel is provided with the Allchin patent double-pin drive, and these wheels can be removed without disturbing the rest of the axle.
Two powerful brakes are fitted; one operates on a drum fixed to the axle, whilst the other acts on a drum bolted to the offside rear wheel. Both brakes operate together, but two controlling pedals are provided, one in the cab conveniently situated by the driver and the
other close to the footboard, so that it can be operated by the second man.
The water supply pump is worked by gearing frOm the crankshaft, a three-toene reduction being employed. The front axle is of the usual centrallypivoted type with a strong laminated , cross spring, the steering being by worm and wheel and chain.
A large water tank is situated under the -body.
_All the wheels are of the wood artillery type shod with North British Clincher tyres.

Ll'he drive is taken through a Ferodo-lined cone clutch of pressed-steel construction to a four. spedand reverse gearbox, a leather disc coupling being interposed. The gearbox is a one-piece casting, fitted with a large inspection cover, on an extension of which is mounted the change-speed operating mechanism. Both engine and gearbox have threepoint suspension, thus rendering them immune from risk of damage owing to twisting of the frame. The final drive is by overhead-type worm gearing, which, together with the differential gear, is slung from the cover of the cast-steel axle casing. The removal of the whole of this gearing is thus rendered a matter of extreme simplicity..
