The entire structure of the turbine and generator is car-ried on a heavy rectangular bed plate, which simply rests uponthe foundation but is not fastened to it with anchor complete unit is 47 ft. long, 13 ft. wide and. 14 ft. highto the top of the gallery railing. Governor.—The necessity for maintaining a very small var-iation in speeds on alternating current units connected inparallel is easily recognized, hence the governor which con-trols the speed of the turbine has been given the closest at-tention and study and is of particular interest. It consistsof a train of levers deriving its motion from worm gearingon the main shaft of the turbine, which actuates an oscillat-ing pilot valve, which in turn actuates the main admissionvalve of the poppet type by varying the steam pressureagainst the piston that lifts it. Steam therefore enters theturbine through this main valve in puffs, the duration of May, 1906. AMERICAN ENGINEER AND RAILROAD GENERAL VIEW OF ENGINE ROOM.
