notes: label: Description
content: This model was submitted to the U.S. Patent Office with the application for the patent issued to Matthias Gabriel, of Newark, NJ, August 6, 1867, no. 67527.
label: Description
content: The engine represented in the model is one of a great many similar designs for rotary steam engines, in which a vane or paddle on a rotary drum fits closely in the annular chamber between the drum and an outer casing and is driven around the chamber by the pressure of steam expanding between the paddle and an abutment that temporarily closes the chamber back of the paddle.
label: Description
content: This engine has two sliding abutments, which are moved in (to close the chamber) and out (to clear the paddle as it passes) by means of a cam on the shaft of the engine and a system of followers and yokes. A plain D-slide valve is operated by pinions and rack from an eccentric on the shaft. Two expansions per revolution are obtained.
