Schofield Rotary Engine, Patent Model

Description
This model was submitted to the U.S. Patent Office with the application for the patent issued to Frederick F. Schofield, of Oscoda, Michigan, September 19, 1876, no. 182291.
This is a rotary engine in which the outer casing rotates and acts a both a flywheel and belt pulley. Otherwise it does not differ materially from the many other rotary engines in which an annular space between a casing and a drum is divided by movable abutments in the out casing, and is traversed by a driving head on the drum. In this case the drum is held stationary and the abutments in the casing are driven around by the pressure between the abutments and the head on the drum.
