Valves and Valve Gear.—The admission and exhaust valves are arranged in the manner already described. The valves are actuated from the side motion shaft by cams having large wearing surfaces. The cams are specialty shaped so as to work the valves quietly, and the valve gear generalty is of an extremely simple construction and of massive strength.
Crank Shaft.—The crank shaft is of Siemens-Martin steel, forged solid throughout, the web being cut out and the whole shaft machined and polished all over. The crank webs are fitted with balance weights to secure steady running, and oil splasher guards are fitted over the crank webs. Special attention has been paid to the proportions of our crank shafts, which are of massive strength relative to the working stresses.
Gear Wheels and Side Shaft.—The side shaft is driven by silent-running worm wheels. The latter are protected with a suitable wheel-guard'.- The side shaft is of ample strength, machined all over and carried in long bearings.
Crank-Pin Lubricator.—A special lubricator is supplied for oiling the crank pin continuously whilst the engine is working. It consists of a steel wiper which collects the oil discharged from the lubricating pump and automatically feeds it into the centre of the crank-pin bearing.
