Inhaltsangabe: This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed.

The engine should always be close to, but not iu the boiler room. Many a high-priced engine has had its days of usefulness shortened by the abrasive action of fine ashes and coal dust coming in contact with the wearing surfaces. There should always be a wall or tight partition between the engine and fire room. The foundations for an engine should be large and deep. Too many manufacturers in marking dimensions on foundation drawings for engines, make them altogether too shallow. The stability of an engine depends more on the depth than on the breadth of the foundations. Stone should be used for foundations rather than brick, but if the latter must be used they should be hard burned and laid in a good cement rather than a lime mortar. If the bottom of the pit dug for the engine foundation be wet, or the soil uncertain in its stability, it is a good plan to make a solid concrete block about a foot and a half thick, on which the foundation may be continued to the top. If such a concrete block be made with the right kind of cement it will be almost as hard and solid as a whole stone. The most economical engine is the one in which high pressure steam can be used during such portion of the stroke as may be necessary, then quickly cut off by a valve which shall not interfere with the exhaust at the opposite end of the cylinder,...
