ROTARY ENGINE.

Specification of Letters Patent.

Application filed April 10, 1912.

Patented Apr. 22, 1913. Serial No. 689,851.

To all whom it may concern:

Be it known that I, HENRY A. REOEN, citizen of the United States of America, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in R0- tary Engines, of which the following is a specification.

My invention relates to rotary engines of the type in which the motive force is derived from the action of steam or other motive fluid admitted between a piston on the rotor and a relatively stationary abutment which periodically moves into the path thereof.

In the ordinary construction of engines of this type either the piston or the abutment reciprocates to enable the one to pass the other during the rotary movement of the element of which the piston forms part, and it is the principal object. of the present invention to provide an engine of very simple construction in which all the moving parts rotate in the performance of their respective functions.

An embodiment of my invention has been shown in the accompanying drawings in the various views of which like parts are s1mi- I larly designated and in which,

taken along the line 2-2, Fig. 1, Fig. 3, an end-elevation of the engine, Fig. 4:, a horizontal section taken along the line H, Fig. i

8, and Figs. 5, 6 and 7 sections similar to that shown in Fig. 2, illustrating different positions of the operative parts of the engine.

Referring more specifically to the drawings, my improved engine consists of a housing 2, the cylindrical body portion 3 of which is supported upon an integral base at. The interior of the body portion is by means of a concentric wall 5, divided into an annular piston-chamber 6 and a steam-chamber 7 which by means of a conduit 8 secured in the end-wall of the housing, connects with a source of motive fluid. The housing 2 is furthermore provided with an annular abutment chamber 9 in which an arcuate abutment 10, hereinafter to be more fully described, has a rotary movement.

The abutment chamber 9 Whose diameter is less than that of the piston chamber, is

placed in intersecting relation to the latter whereby it is divided into two arcuate sections, one of which extends through an internal enlargement 12 of thedividing wall 5, while the other extends through the engine-base 4.

A valve-chamber formed in the interior enlargement of the dividing wall, in communication with thesteam-chamber 7, is designed to be occupied by a rotary valve 13, the stem 14 of which projects through a combined stuffing-box and bearing 15 which forms part of a screw-plug 16 by which the open end of the valve-chamber is normally closed.

The valve 13 is composed of a hollow cylinder, the interior of which is in continuous communication with the steam-chamber by an opening in its end, and it is provided with a longitudinal slot 17 through which the steam is periodically admitted into a port 18 which by means of a channel 19 ton-chamber 6.

The port 20 is located at the lower portion of the piston chamber intermediate the entrances to the upper section of the abutment chamber, in a line passing through the centers of the two annular chambers, and a Figure 1 represents a vertical section through the engine, in the plane of the axis of rotation of its rotor, Fig. 2, a section a port 21 located in the same line at the upper portion of the piston chamber serves toexhaust the spent motive fluid therefrom into a conduit 22. w

The rotor of the engine is composed of a disk 23 fixedly secured upon the engine shaft 24 which'is rotatably supported in an axial bore of the enlargement 12 of the dividing wall 5 and in

bearings

25 and 26 formed integral wit-l1 the end-wall of the housing and with a head 27 which normally closes the opposite, open end of the same.

The disk 23 is movably disposed between the end-wall 28 of the steam-chest defined by the circular wall 5 and the inner surface of the head 27, and it carries a piston 29 which, projecting laterally from its peripheral portion, is movably fitted between the circular inner and outer walls of the annular piston chamber 6.

The rotary abutment 10 which is fitted to move within the abutment-chamber 9, projects laterally from a disk 30 which being movably disposed in a recess at the end of the housing opposite to that closed by the head 27, is by means of an integral shaft 32 rotatably supported in a bearing 31 on a plate 32 which normally closes the recess in which the disk has its movement.

The corresponding ends of the valve stem 1% and the two shafts 2st and 32 are connected to move in unison at equal rates of speed by means of a train of gearw'heels 33, best shown in Fig. 3 of the drawings, and a fly-wheel 34 is mounted on the opposite end of the rotor-shaft for the usual purpose.

The end-faces 35 of the piston 29 curve divergently from its inner face which contacts with the inner wall of the chamber 6 to its outer face which engages the opposite wall of the same, and when the parts are in their dead center, as shown in Fig. 2, the piston extending centrally in alinement with the centers of the two annular chambers, closes with its inner face, the port 20 and with its outer face the entrances to the lower section of the abutment chamber, while its curved end surfaces are engaged by the ends of the abutment 10.

The valve 13 is at the same time in the position in which its longitudinal slot 17 registers with the orifice 18 of the channel 19 so that when the rotor is moved in the direction of the arrow a in Fig. 2, the motive fluid contained in the steam chest 7, will be'admitted into the space 36 between the abutment and the rear end-face of the piston as soon as the latter uncovers the port 20, and by its expansive force, drive the piston onward.

The abutment 10 moving in unison with the piston 20 in the direction of the arrow 0, will remain in contact therewith until the end of the piston rearmost with relation to its direction of rotation has passed the adjacent entrance to the lower section of the abutment chamber, when the abutment entering the same will partition the pistonchamber at that point, as shown in Fig. 6 of the drawings;

The valve 13 which likewise moves in unison with the rotor in the direction of the arrow (Z will cover the port 18 only after the piston 29 has moved through an arc of approximately ninety degrees, when it is driven further onward by expansion of the body of motive fluid confined between its end surface and the abutment, until it passes the exhaust port 21 through which the motive fluid escapes from the piston chamber.

During the subsequent downward motion of the piston, the rotor is impelled by its own momentum and that of the fly-wheel 3 1, until the piston again passes the port 20 when a fresh supply of motive fluid is admitted in the space 36 and the above described operation is repeated.

In Fig. 5 of the drawings, the parts are shown in the position they occupy at the moment steam is admitted into the space between the piston and the. abutment, Fig.

6 shows the parts when the steam-supply is shut off by the valve and the rotor is imcharge the steam at an earlier or later period in the rotary movement of the piston, and that the efficiency of the engine may be increased by providing two pistons at diametrically opposite points on the rotor, in which case the gearing is changed to cause the abutment to make two complete revolutions while the piston makes one, and the valve is provided with two slots 17.

It will furthermore be observed that by reversing the exhaust and intake openings, the engine may be employed to operate as a pump for raising or circulating water or other fluid.

Having thus described my invention what I claim and desire to secure by Letters- Patent is:
