SPECIFICATION forming part of Letters Patent N o. 466,318, dated January 5, 1892. Application tiled August 14, 1891l Serial No. 402,665. (No model.)

To all whom it may concern:

. Be it known that I, WILLIAM BEATY, a citizen of the United States, residing at Silver.,- ton, in the county of Jackson and State of West Virginia, have invented a new and useful Steam-Engine, of which the following is aspeciiication.

My Invention relates to rotary steam-engines; and it has for its object to provide an engine that will be simple in construction and effective in operation and one that will fully utilize the steam admitted thereto' and at the same time will give a greater proportion of power to the amount of steam than in the ordinary engine of this class; and with the objects in view that are to be attained by this improvement theinvention consists in a rotating cylinder constructed and operated in. the novel manner hereinafter fully described, illustrated in the accompanying drawings, and specifically pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a vertical longitudinal sectional view of a ro,-

section of the same.

tary steam-engine constructed in accordance with myinvention. Fig. 2 is avertical cross- Fig. 3 is a plan view of the stationary valve-operating disk. Fig. et is a detail in perspective of the steam-regulat-ing core. Y f

Referring tothe accompanying drawings, 1 designates a suitably-constructed bed or framefwork supporting the various parts of the engine. Rigidly secured in opposite sides of said bed is a hollow stationary shaft 2, which is provided with a central annular flange or disk 3, provided on its upper periphery with the'lug or projection 4. Revolubly mounted upon said stationary shaft and inclosing the iiange thereon is the main cylinder 5, into vwhich steam is conducted for the purpose of revolving the same and from which motion is imparted to the machine to be operated by the engine. The said cylinder or casing 5 is provided on opposite sides of its inner periphery with the oppositely-disposed and operating wings or valves '6, which are mounted upon the operating-stems 7. AThese valves are designed to bear snugly against theannular iiange or disk 3 during the revolution of the cylinder. therearound, and .when the same approach the stationarylug or proautomatically turned away from said iiange or disk and into the'notched recesses 8,10- cated on the inner periphery 0f the cylilideI-, casing, and which, when the valves are seated therein, form a continuous. line with the rest of the inner periphery of the' casing or cylinder, and thus allow the cylinder to easily pass over said lug or projection, which is designed to bear tightly against the inner face or circu Inference of the cylinder or casing during its revolution. The valve-stems 7, carrying the wings or valves and located on either side of the in wardly-projecting division lugs or shoulders 9, are journaled in both sides of the casing; but `the inner ends of the same project without one side of the casing and terminate in the crank-arms 10, the endsof which are designed to work within the elliptical groove 11, formed in the inner face of the stationary stationary shaft and adjacent to the revolving rrcylginder; 'which during its revolution around the annular flange or disk causes the crankarms to follow said elliptical groove, and as the valves approach the lug or projection thereon the said arms are at the apex of said groove, and thereby immediately throwv the valves away from the said Bange or disk and into their recessed seats previously referred to. The elliptical groove 1l in said stationary disk 12 at its upper terminal is providedwith an upwardly-extending squared' portion 11,

that allows the said crank-arms to-be thrown fully within their seats, in order that/they may readily clear the projecting lug et.

Steam is admitted within the cylinder through the hollow shaft 2 from the inlet end 13 thereof, and the same is regulated by means ofthe revolving core 14, located land operated therein, and, according to the way in which the engine is desired to be operated, the steam is admitted within the cylinder on either side of the lug or projection` on the stationary flange ordisk through either .one of the steam-openings 15, formed in said iiange or disk on both sides of the lug or projection thereon,and communicate with the interior of the hollow shaft. When steam is admitted IOO capacity ot an exhaust-opening, while the same is reversed when steam is admitted in the opposite way. The rotating core 14 extends through the entirelength of said hollow shaft from the inlet-opening 13 to the opposite end of the shaft, and extending Without the same is connected to and operated by the lever 16, which is designed to either reverse the engine, control the amount of steam, or stop the same, as may be desired. The said core is provided with a longitudinal groove 17, which extends from the steam-inlet up to about the center of said hollow shaft and directly beneath the steam-openings therein and in the annular flange or disk thereon, so as the said core is turned in either direction the end of said groove communicates with either steam-opening, according' to the direction in which it is desired to revolve the engine. The remainder of the core 14 for the rest of its length is provided with an exhaust-couducting groove 18, which when the terminal of the livesteam groove communicates with the .steam-opening on one side of the lug or projection theinner terminal of the exhaustgroove communicates with the opposite steamopening and conducts the exhaust-steam to the opposite end of the core, whichis provided with a cross-groove 19, communicating with the main exhaust-groove, and which in turn 1s 1n communication with the exhaust-pipe 20, located in the side of the supporting-bed. Vhen the engine is reversed and running in the reverse direction, the inner terminal ot the exhaust-groove 18 does not register with the opening opposite to the live-steam opening in the annular iange or disk, and to place said groove in communication with the eX haust-opening the core is further provided with a circular or cross groove 21, which communicates with both the longitudinal exhaustgroove and the exhaust-opening in said fiange. Spring-packing 22 is inserted in grooves in the ends of the wings or valves in order to reduce the friction between the same and the center flange around which they revolve, and similar packing is also inserted in groovesin the sides and ends of said lug or projection for similar purposes-that is, to reduce friction between the same and the cylinder or casingr revolving therearound.

It is thought that the construction and operation of my improved rotary engine are now apparent without further description. The steam being admitted within the hollow shaft is controlled by the revolving core therein and conducted directly to within the revolving cylinder, mounted upon said shaft on Veither side of the lug or projection upon the annular flange or disk thereon. The steam bears against the wings or valves, which follow the periphery of the said annular flange or disk and are resting upon the division lugs or shoulders 9, and thus causes the cylinder to revolve and impart motion to the machinery v desired, and as the valves approach the lug or projection by the mechanism described they are thrown off and away from the annular flange and pass over said lug, while the steam escapes through the opposite opening to that from which it was admitted and passes through the hollow shaft without the engine. B y reversing the core Within the hollow shaft, in order to direct the steam in a reverse direction, the engine is rotated in the opposite direction, while, when desired, the said core may be so turned as to prevent the steam from entering either opening within the cylinder or casing, and may be thus stopped or started at will. It can be readily seen that by .the arrangement ot' the operating-valves on both sides of the division lugs or shoulders formed by the recess valve-seat within the sides of the casing when the said valves are resting upon the flange or disk the pressure of the steam exerted thereon will not be upon the operating-cranks and the flange, but uponsaid shoulders, which form more compact and steam-tight joints with said valves as the pressure of the steam increases in the force which it exerts upon said valves. Slanting steam-grooves23 are formed in the periphery of said flange or disk and communicate with the steam-openings on either side of the post thereon, the purpose of which is to permit the steam to begin to escape before the valve begins to rise up within its seat, inasmuch as the pressure of the steam would prevent the valve from rising within the same if it was not allowed to escape prior to the rising of the valve. It

may also be noted at this point that the engine may be constructed having one or more posts or lugs, each of which is designed to have two separate sets of Valves for operating thereover, and other minor details of construction may be used without departing from the spirit of my invention.

Various methods may be employed to iinpart motion from the revolving cylinder to the machinery to be operated. A simple and convenient expedient is to provide the periphery of the cylinder with one or more rows links of an ordinary chain belting, which connects with sprocket-gear of the machinery to be operated. As implied, several rows of the teeth or cogs may be placed around the cylinder to operate different belting and dierent machinery. This method is of course only a preferable one, for motion can readily be imparted from the engine to the machinery by means of ordinary belting or other suitable connecting means Without departing from the spirit of the present invention.

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