ROBERT AUGER, OF NEW YORK, N. Y.

ROTARY ENGINE.

SPECIFICATION forming part of Letters Patent No. 338,688, dated March 30, 1886.

Application filed January 30, 1886. Serial No. 190,333. (No model.)

To all whom it may concern.-

Be it known that I, ROBERT AUGER, of the city of New York, county and State of New York, have invented a new and Improved Rotary Engine, of which the following specification is a full, clear, and exact description.

This invention relates to rotary engines wherein the central part provided with a sliding abutment is held stationary and the outer shell or casing with the stationary abutment is made to revolve.

Theinvention consists of the various elements of improvement fully described in the following specification.

In the accompanying drawings, Figure I represents a vertical section of the engine. Fig. II is a vertical crosssection of the same on line 2 3, Fig. I. Fig. III is an inside view of part of the ring or casing, showing the face of the abutment attached to the same. Fig. 1V is a top view, and Fig. V a side view, of packing for the abutment.

Between two disks. A A, a central hub, B, is arranged. One of the disks, A, is cast in one piece with the hub, while the disk A is securely fastened to the same by a number of bolts, a. These disks, with their hub, are held stationary by suitable frames or supports. (Not shown in the drawings.) Be tween and around the periphery of these disks aring or casing, G, is fitted, capable of turning, and made steanrtight by packingrings b 1).

Around the ring or casing a belt may be placed, or its periphery may be provided with teeth meshing into corresponding teeth of an adjoining wheel or pinion, for the purpose of transmitting the motion.

On the inside of the ring or casing O the abutment D is arranged, extending to the periphery of the central hub, B, and provided with packing, hereinafter more fully described. In the hub B a movable abutment, E, is arranged, attached to a rod, a, passing through astuffing-box, m, and is acted upon by a spring, 8, to force the outer end of this abutment against the inner surface of the ring or casing O.

F is the opening for the admission of the steam passing through the disk A, placed close to and behind the abutment E, and G is the opening for the escape of the steam passing through the disk A, and so arranged that this opening is closed by the surface of the abutment E; but both openings may be arranged on one and the same side in one of the disks.

The abutment E is made in two parts, connected by screws 1) '0, (see Figs. VI and VII,) whereby the same can be regulated and extended in one direction by the screw 12, so that its sides will fit tight against the inner surfaces of the disks A A, and likewise be extended by means of the screw 1;, so that it will fit tight against the sides in the cavity of the hub B.

The abutment D is made tight against the circumference of the hub B and against the surfaces of the disks A A by plates 10 w and 'w, fitting into suitable recesses made in the abutment and acted upon by springs r r and 1-. (See Figs. IV and V.)

The operation is as follows: Steam, air, or any other pressure being admitted through F will act against the end of the abutment D and force the same, together with the ring or casing 0, around in the direction of the arrow, Fig. I.

When the abutment arrives near the abutment E in the stationary hub B, it will force the same inward against the action of the spring 8, covering at the same time the opening F, while by this inward motion of the abutment E the opening G will be uncovered, so as to allow the steam or other pressure to escape.

\Vhat I claim is 1. The combination of stationary disks A A with central hub, B, and revolving ring or casing G with stationary abutment D, having tapering sides, and with the movable abutment E, all being so arranged that the abutment E is operated by the tapering sides of the abutment D, as and for the purpose described.

2. The combination of disks A A, hub B, ring 0, with the inlet-pipe F, outlet-pipe G, and with the tapering abutment D, and sliding abutment E, all being so constructed that the abutment D serves as a valve for the inletpipe F and the abutment E as a valve for the outlet-pipe G, as and for the purpose set forth.

ROBERT AUGER.
