Leuchsenring Rotary Water Engine, Patent Model

Description
This model was submitted to the U.S. Patent Office with the application for the patent issued to Robert Leuchsenring, of New Bedford, Massachusetts, March 9, 1880, no. 225226.
This is a form of engine in which a drum-shaped rotor turns in a casing, which is eccentric to the center of the drum, so that the drum runs against one part of the casing and a crescent-shaped annular space is formed between the casing and the drum. Water is admitted tangentially to the drum to one side of and away from the point at which the drum and casing meet. The water impinges upon abutments on the drum, turns the drum, and discharges from the engine about two-thirds of the way around the casing. The abutments on the drum slide into the drum to pass the casing and are held against the casings by springs.
