No. F •^ CROSS-SECTION OF POWER STATION of three 500-bp two-phase generators and two 500-hp direct-current machines, each connected to a 500-hp West- inghouse compound engine. These machines are already in operation, and there is being erected an additional 500-hp direct-current gener-ator, direct-connected to a 500-hp steeple-compound Westinghouse engine of a new t}pe. Each of the generators rests on a bedplate in common with its engine, to which it is direct connected by means of a flexible coupling. The space occupied by the steeple engine and it=, dynamo is only 17 feet by 8 feet 6 inches; the other five double units occupy a space 22feet by 8 feet 6 inches. There is also installeda revolving transformer, or two-phase motor,used for driving a direct-current arc-lightingmachine, and also for supplying the excitingcurrent for the fields of the polyphase gen-erators. An overhead crane affords a quickand convenient method of handling apparatusto be installed or repaired. Th
