To all whom it may concern:

Be it known that I, JAMES IV. MOONEY, a citizen of the UnitedStates, residing at Lawton, in the countyof Comanche and State of Oklahoma, have invented certain new and useful Improvements in Rotary tinuously and effectively rotate a power shaft actuated bythe driving elements as a unit without lost motion.

The principle involved in this motor is the direct action of the motive agent on a pair of synchronously operating cylinders which are eccentrically disposed within a stationary casing, and which furthermore, are equipped with a common piston and appurtenant valve mechanism arranged in such a manner as to alternately form abutments or pockets of reversely varying steam capacity, the formation of said chests or pockets being in consonance with the relative positions of the two cooperating revolving cylinders, considered as an entirety,.and the stationary cylinder or casing. The pockets in their cycle rapidly move and receive the motive agent simultaneously without the least fluctuation and with obvious advanta es in overcoming the obstructive influence of dead center, and in materially reducing wear of the moving parts as well as insuring an effective and positive application of the motive agent.

Specifically the invention contemplates the association of cooperating mechanical devices contributing to the practical operation of the motor and which will be more fully hereinafter specified in preferred form, but'subje'ct to such modifications as fairly fall within the scope of the claims.

y In said drawings :Figure I is a side ele vation of a rotary motor embodying features of the invention. Fig. II is a longitudinal vertical section of'the motor. Fig. III is a transverse vertical section taken along lines 33 of Fig. I. Fig. IV is a transverse verinner revolving cylinder. elevation of one of the revolving cyllnders,

The numeral 5 designates a tubular cylinder having opposed heads (6), and fixedly secured to any suitable base by the supports (7). Within the inclosure (5) and extending longitudinally and concentrically therethrough and the heads (6) is a power shaft (8), having a shoulder (8) which contacts with the inner sides of said heads and being provided with stuffing boxes (9) and (10),

secured to the heads, to obstruct leakage.

Exteriorly of the heads (6) the shaft (8) is supported by suitable pillars or uprights (11). At all points lubricating devices for the purpose will be provided. Each of the heads (6) is provided with annular compartments (12) and (13) separated by the transversely extending circular partition (14).

Freelymovable within the inclosure (5) and the head (6) are a pair of eccentrically arranged revolving cylinders (15) and (16), the cylinder (15) being the smaller and inclosed within the cylinder (16). As clearly exhibited in Figs. II, III and V, the cylinders are equipped with steam inlet and eX- haust chests (17 and (18), the said compartments extending circumferentially with respect to the cylinders and being separated by the partitions (19) so as each of the said chests will occupy adiameter of the cylinders. Communication is established between the outer and inner cylinders by the passages (19 in the partition (14). To insure a perfect and reliable bearing for the cylinders and counteract endwise pressure I provide intermediate the ends thereof the outwardly and inwardly circumferentially projectin shoulders (20) and (21), the said shoulc ers being designed to lie contiguous relative to each other, as clearly shown in shaft (8) (23) ,the said slot (22) being at all times in registration and communication with the steam inlet chambers (12) and (13), and the slots (23) being slmilarly disposed with respect to the analogous exhaust chambers (12) and (13), formed in the opposite head (6). Obviously, I provide the steam feed pipe (24) and the steam exhaust pipe (25), which are suitably secured to the head (6). Extending longitudinally of each cylinder, and having lengths equal to the length of the shoulders (20) and (21) is a slot (26) having on opposite sides thereof a plurality of steam ingress ports (27 and a like number of exhaust ports (28), the influx and efflux of the steam through said openings being controlled by the oscillatory valve (29), which comprises a shaft (30) having a plurality of suitably spaced projections ('31) and an oppositely disposed integrally formed solid body portion (32) the ends of the shaft (30) being rotatably mounted within the re movable bearing plates (33). Keyed to the relatively concentrically therewith is a piston (34) which projects through the and at all times lies-contiguousthe inner circumference of the stationary'cylinder To that end I deem it expedient to provide a suitable packing, such at 36, to minimize friction of these parts. In order to thoroughly equalize the closed by the valve (29) leverage of the steam pressure and consequently obtain advantageous results it is very important that the distances between the outer cylinder (16) and the stationary cylinder (5), as indicated by the arrow (37), and between the shaft (8) and the inner side of the smaller cylinder (15), as shown by arrow (38), and the sum of the spaces, designated by arrows 37 and 38 be equal to thedistance (designated by arrow 39-) between the cylinders (15) and (16).

In practical operation the steam is admitted through the inlet (24) and thence into the annular chambers (12) and to which said inlet is connected, as hereinbefore described, and "finally into the steam chests (17) of the revolving cylinder, thus forming steam headings in spaces indicated by a, b and 0; Now assuming that the piston is traveling to the left from the position shown in Fig. III of the accompanying drawings steam will be admitted through the ingress ports (27) to both spaces a and b. This operation continues until the piston reaches a point diametrically opposite its initial starting position, atfwhich time the ports (27) are and the steam passes into a. The motive fluid which remains in spaces 7) and c expands until the piston traverses the lower central portion of the stationary inclosure (5) when the exhaust ports (28) are opened and the steam is excluded from space a and again thrown into spaces 6 an( 0. It will thus be observed that the cylinders and (16) work synchronously and that the piston travels tangentially with respect thereto, that is, during its first and second half of its travel, but when said piston is in a vertical position whether it is in contact with the upper inner circumference or the lower inner circun'iference of the outer stationary cylinder, it is parallel with said stationary inder and the revolving cylinders, the said piston, furthermore, being so constructed and arranged as to automatically operate the valves to alternately open and close the exit openings of the steam chests and the exhaust chests.
