Description
This model was submitted to the U.S. Patent Office with the application for the patent issued to Charles Miller, of Belleville, Illinois, May 3, 1859, no. 23852.
The engine has two oval pistons or cams each running in a separate circular cylinder or casing. Sliding abutments in the casing bearing on the edges of the cams direct the steam in the forward direction around the casing. Admission of steam is controlled by two flat slide valves working in steam chests on top of the casing. The valves are operated by two eccentrics on the engine shaft. The engine is reversible.
