ROTARY ENGINE.
SPECEFCATON forming part of Letters Patent No. 677,531, dated July 2, 1901.
Application filed July 17, 1899. Serial No. 724,149. (ll'o model.)
'Q @ZZ whom, t may concern,.-
Beit known that I, ELMER E. ALBERT, a citizen of the United States, residing at Malta, in the county of Cassia, State of Idaho, have invented certain new and useful Improvements in Rotary Steam-Engines; and I do declare the following to be afull, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention resides in the combination and arrangement of parts hereinafter described, and particularly pointed out in the claims.
In the accompanying drawings, Figure l is a sectional view of my invention, taken transversely of the shaft, parts being shown in side elevation. Fig. 2 isa sectional view of my invention, taken longitudinally of the shaft.
In the drawings, lis the base of the engine; 2, the cylinder; 3, the piston fixed by a key onto the shaft 5.
4 is an abutment-plate, which is carried at its inner end upon the free end of an arm 4X,
which is pivoted to the cylinder-casing at 15.
The piston, it will be seen, is of cam shape, and the inner end of the abutment-plate is intended to ride on the surface of the piston, said plate being free to move for this purpose in and out through the cylinder-shell, a packed joint being provided at The cylinder-casing is formed with a recess at y to receive the arm 4X when this swings outwardly. This `arm is formed on a curve corresponding to piston is provided with a packing-strip 9, which is spring-pressed to provide a goody yielding contact with the cylinder, and a similar packing-strip 10 is inserted in a recess in the side face of the piston. (Shown .in dotted lines in the drawings.) The abutment-plate 4L is provided with a spring-actuated strip in one of its edges.
6 indicates the inlet-port. This is arranged inder behind the piston near the high part thereof. Fig. l shows the parts in position to receive steam behind the piston and in front of the abutment-t'. e., in the space 16- j and the steam in this space acting on the pistons sets,the same in rotation.' The exhaustport is shown at 11, and the steam escapes through this when the arm 4X is forced outwardly by the high part of the cam-shaped piston.
Having thus described my invention, what is claimed, and desired to be secured by Letters Patent, is-
l. In combination with the cylinder and piston, an abutment-plate freely movable toward and from the center of the cylinder to rest on the piston at all times and a pivoted arm carrying the said abutment-plate, said arm being formed on a curve corresponding substantially to that of the inner periphery of the cylinder, said abutment-plate being pivoted adjacent to the inner periphery of the cylinder with its inner surface arranged to form a continuation of the inner surface of the cylinder, substantially as described.
2. In combination, the cylinder, the piston and the abutment comprising a pivoted arm with a spring for forcing the arm constantly toward thepiston and the abutment-plate connected with the end of the same and extending outwardly from the said arm, said arm being curved and forming a continuation of the inner periphery of the cylinder when said arm is in its outermost position, substantially as describe( E. E. ALBERT.
