Elijah Leonard started E. Leonard & Sons in London, Ontario in the year 1840. The shop manufactured agricultural and railroad equipment, but mainly manufactured steam boilers and steam engines. Elijah Leonard became mayor of London in 1857. The engine was donated by McRae Lumber Co., a lumbering shop operating in the Algonquin park area since 1922. - Function
-
Steam engine powered by steam which moves a piston back and forth by expansion and compression. This is a Corliss model, which could subject the speed to precise control because it could automatically vary the length of time during which steam would enter the cylinder due to a system of oscillating valves. Steam at atmospheric pressure would fill up the space underneath a piston in a cylinder while it was lifted by a counterweight beam. - Technical
-
Corliss engines were very user-friendly and were capable of delivering a uniform flow of power in spite of sudden changes in load. They permitted higher speeds while reducing the frequency of breakage in threads. Mainly used in the textile and metallurgy industries. Used four semi-rotary valves, two for the admission of steam and two for exhaust. Stationary engine, 20x36inches, 90rpm. - Area Notes
