14,665. Edwards, A. G. June 25. Movable - abutment type having rotating abutments. In a simple rotary abutment engine, the steam is admitted and exhausted at both ends through annular ports which communicate with annular chambers inside the piston. The admission chamber communicates with the working chamber by a port behind the piston, and the exhaust chamber by a port before it. A cut-off plate 15 is fitted into each annular admission port. It is secured by a screw which passes through a slot in the casing so that the position of the plate may be adjusted.
