example of a late 19th-century Corliss-type steam engine
This 350-horsepower Corliss type steam engine is an example of a typical late nineteenth century steam engine. The essential feature of Corliss type engines is the valves that admit steam to and exhaust it from the cylinder. The Corliss valve gear made the engine extremely efficient in steam consumption and was the most efficient system for controlling low to medium speed engines.
This particular engine operated for more than eighty years, having been retired not by age but over concern for stack emissions by the U.S. Environmental Protection Agency. The engine was built by the William A. Harris steam engine company of Providence, Rhode Island (at one time the world center for steam engine manufacturing), and was first used at Atlanta's Cotton States and International Exposition of 1895, Piedmont Park, Atlanta.
