IMPROVEMENT IN ROTARY ENGINES.

Specification forming part of Letters Patent No. 176,878, dated May 2, 1876; application led February 28, 1876.

To all whom it may concern Be it known that I, J osEPHUs MooEE, o Mound Valley, in the county of Labette and State of Kansas, have invented a new and Improved Rotary Engine, of which the following is a specification This invention consists of avpair of cylinders. with pistons set opposite, eachother for one to take steam when the other is not taking it, with abutments which slide out and in to let the pistons pass, and are worked by cam-disks outside of the cylinders; also with two sets of slide-valves for running theengine either way, the valves being workedby eccentrics on the shaft outside of the cai e, and also with two sets of exhaust-ports for use according tothe way the engine runs, the valves of which are connected to the reversing-valves, so as to shift simultaneously with them.

The steamways are constructed in the form of a round ring, and the pistons are in the form of a segment of a ring, and are attached to the edge lof a disk keyed on the shaft, so as to be fitted with ordinary round pistonpacking.

Figure l is a sectional elevation of my improved engine, taken on the line a; .fr ot' Fig. 2. Fig. 2 is a sectional elevation taken on line y y of Fig. l. Fig. 3 is a side elevation.

Fig. 4 Ls a top view, and Fig. 5 is an elevation of the piston. Y

Similar letters of reference indicate corresponding parts. v

A represents the steamways arranged side by side around the shaft B, on which are the disks C, each having a piston, D, on its periphery, running in one of the steamways. E represents the slidin g' abutments, which are worked by the grooved cams F and bars Gr, one being raised when the other is down. H and I are two inlet-ports to each cylinder,

ports I, of both engines, said valves beingl Worked by thev eccentrics N and rods O. P is a reversing-valve, and R S exhaust-valves,

both of the latter being connected to the lever' 'l of the reversing-valve, so that when steam is admitted at H to run the engine to the left the exhaust-port J will b e closed by valve R, and port K will be opened, and when admitted atl, to run to the right, portK will be closed and J opened.

' The round form oi' the piston is represented in Fig. 5, showing the connection ot' it to the disk by the center stud U and bracket W. This form enables it .to be packed all round, the same as the piston otA reciprocating engines, or better than the angular form commonly used in rotary engines. The steam may be Worked expansively in this contrivance by setting the eccentrics to cut o" in advance of the exhaust, or, in other words, before the pistons arrive at the exhaust-ports.

Having thus described my invention, I claim as new and desire to secure by Letters Patcnt- 1. rlhe combination, in a rotary stcal'n-engine, of the two parallel steam-chambers A,
