The engines and generators aresimilar in design to those furnished the MetropoHtan Rail-way Company, of Manhattan, but the relative positions ofthe cylinders, fly-wheel and generator is somewhat dif-ferent. The accompanying drawing shows the generalarrangement. There are three bearings, one of which is. 4000-HP. GENERATING UNITS F an i)utl.)oard bearing on the far side of the generator. Thefly-wheel is placed between the generator and the middlebearing, and the low-pressure cylinder is the nearer to thefly-wheel and generator. The connecting rod of the high-pressure cylinder is connected to the shaft by a disc crankat its end. The sizes of the cylinders are 42 ins. x 86 ins. x60 ins. stroke, and the engines run at a speed of 75 r. p. both high and low-pressure cylinders the valve gearis of the Corliss pattern, and the steam pressure is 175 each engine is connected a Worthington diameter of the two engine bearings is 27 ins., andeach is 42 ins. in length, the central bearing being dividedas shown; the outward bearing is 30 ins. in diameter and56 ins. long. In the generator the diameter of the shaft,which is of hollow-forged steel, is 35 ins. The weight ofthe 28-ft. fl}-wheel is 240,000 lbs. The first installation of exciters will consist of two units.
