The illustration above is reproduced from a photograph of a set of triple-expansion engines constructed by Messrs. Alexander Shanks and Son, Arbroath, for Messrs. Whitehead and Co., the torpedo constructors, and is intended for driving the machinery in their new works at Weymouth. The engine is of the ordinary vertical surface-condensing type, the cylinders being 8½ in., 13½ in., and 22 in. in diameter respectively, and the stroke of pistons 18 in. Automatic expansion gear is fitted, the main and expansion valves for the high-pressure cylinders being of the piston type. One of the back columns acts as an air vessel for the air-pumps, and the circulating pump has an air vessel on both suction and discharge. The cylinders are lagged with planished steel. The engine is very complete. It is fitted with improved sight-feed lubricators, steam starting gear, ladders, handrails, &c, for easy access to the various parts, as well as relief valves, indicator gear, &c. The flywheel is 6 ft. in diameter and 16 in. wide, and is crowned for belt driving. Working with steam at 150 lb. pressure, the engine is capable of indicating 100 indicated horse-power. |
