Stationary steam engines, simple and compound; especially as adapted to electric lighting purposes . This Instrument gives records simultaneously of the steam or watepressure and of the speed of engines or machinery. Both are recordeupon the same chart, continuously and accurately. The width of the loops in above tracing (lower line) indicate the lengof time the speed was interrupted—as of a train of cars—and between whats^tions, and whether unlawful speed was afterwards resorted to, in recover-ing the lost time or opportunity. Perfection in electric lighting cannot be reached until uniformity sharbo secured; hence, Dynamo Engines must be automatically watched, anddata obtained and preserved for comparisons of work performed and resultsobtained from time to time. Full instructions for unpacking, setting up and running alwayssent with instrument.
