Lyman Edward. The Use of The Steam-Engine Indicator: or, Practical Science for Practical Men

New Haven: 1874. — 133 p.The Steam-engine Indicator is a small instrument (see Frontispiece) which may be attached at any time to the cylinder of a steam-engine, at either end or both, by a pipe usually about half an inch in diameter. Then, by attaching the cord of the Indicator to some part of the engine having motion coincident with the piston, and placing a piece of paper upon the cylinder of the Indicator, admitting steam through the pipe, and then applying the pencil of the Indicator to the paper, a card or diagram is traced. This is done when the engine is regularly working, either loaded heavily or light, making no delay to the manufacturing business to which the engine is attached.Description of the Indicator
