Stationary steam engines, simple and compound; especially as adapted to light and power plants . o 60 pounds per H. P.,and permitting variation of work through wide ranges with-out arcing or other difficulty. The cut on page 270 shows a straight-line engineconnected to a General Electric Companys from the adjustable outboard pedestal, the base,pedestals, and dynamo-supports are cast in one piece, whereit can be placed if in one piece, and the whole arranged tobe filled with masonry before setting on foundation. The arrangement for connection between engine anddynamo includes a safety-coupling between the two. Aflange is forged on the dynamo-shaft, a cone is keyed andpinned on the engine-shaft, and a solid bush is bolted to theflange and drawn on the cone so as to create driving-friction 1. For details of this interesting construction see the papers of Prof. H. J. Ryanand of M. P. Thompson. 270 STEAM ENGINES FOR enough to run the dynamo, but not so much as to burn itout in case of a short circuit.
