Rayner.
Messrs. T. J. Rayner and Sons, of Rayleigh, Essex, show a 5-ton steam lorry.

The engine is fitted with the company's own type of revers Ing gem-, which gives a variable cut-off with a constant lead. A loco-. type of boiler is fitted, and a top feed is employed for the fuel. This lorry on exhibition is supplied with two gear ratios, which are operated by the usual hand lever ; these gears and the whole of the working portions of the engine are enclosed in a dust-proof and oil-tight casing. The differential-gear casing is cast integrally with the engine bed proper, and an examination of the engine and gears can be made without moving the load on the platform. The final transmission is by Hans Renold roller chains.
A feature of the design is the adequate brakingpower which has been provided. In addition to an internally-expanding brake on each of the back wheels, there are two of the band type, placed one at each outer end of the differential shaft, just inside the chain sprockets. The back axle is circular in section, and large wearing surfaces are provided. The front axle has been designed to take the company's own steering gear, which is fitted with ball bearings, and the whole of its details are " boxed up " in an oil-tight casing.
