The, Harrisburg Tandem-Compound Engine—The Ide tandem-compound engine, as manufactured by the Foundry and Machine Department, at Harrisburg, Pa., is shown in Fig. 41. The extra heavy shaft and fly-wheel are supported between the bearings, avoiding the overhang of the fly-wheel, as is the case in the center-crank type. One of the special features in the Harrisburg tandem compound is the method of connecting the high and low pressure cylinders. It admits of moving the low-pressure cylinder head into the connections to examine the low-pressure cylinder and piston without removing the high-pressure cylinder or its steam and exhaust connections. The inability to do this has been one of the greatest objections to the tandem-compound engines as usually built. The manner of supporting the high pressure cylinder is more substantial than the general practice, avoiding the vibration of cylinders when working under full load. |
