The Westinghouse Farm Engine was a small, vertical-boiler steam engine built by the Westinghouse Company that emerged in the late 19th century.
In the transition from horses to machinery, small portable engines were hauled by horses from farm to farm to give power where it was needed.
The cylinder, steam chest, cross-head guide, and the boxes for the crankshaft bearings were all cast in a single piece to assure mechanical exactness and perfect alignment of piston and crank.
The Westinghouse Farm engine was said to have a short, quick stroke to make it lighter.
[2] The engines were equipped with an adjustable governor, pop safety valve, steam gauge, feedwater heater, direct-acting pump, whistle, blower, brake, and a full supply of wrenches and fire tools.
