ROTARY ENGINE.

SPECIFICATION forming part of Letters Patent No. 776,376, dated November 29, 1904.

Application led October 10, 1904. Serial No. 227,867. (No model.)

T0 LZZ whom, it puny concern:

Be it known that I, JOHN A. S. BECKER, a citizen of the United States of America, residing at Freeport, in the county of Stephenson and State of Illinois, have invented certain new and useful Improvements in Rotary Engines, of which the following is a specification.

My invention relates to improvements in rotary engines; and it consists of the novel construction, arrangement, and combinations of parts hereinafter fully described, and specifically pointed out in the claims.

Referring' to the accompanying' drawings, which form a part of this specification, Figure l is a side elevation of an engine embodying my invention. Fig. 2 is a transverse section at the dotted line 2 2 in Fig. 1. Fig'. 3 is a central section of the engine at the dotted line 3 3 in Fig. Q. Fig. 4 is a section at the dotted line 4 4 in Fig. 2 of parts there shown. Fig. 5 is an isometrica] detail view of the valve of the engine.

Like letters of reference indicate corresponding parts throughout the several views.

A is the frame of the engine and has circular bearings A A2 therein.

B is the driving-shaft of the` engine and is mounted in the bearing A2 in the frame A.

B is the crank-shaft of the engine and is mounted in the bearing A' in the frame A and in a bushing, to be described hereinafter, inserted through and supported by a stationary part, also to be described hereinafter. The inner end portion of the shaft B is also provided with a duct B2, extending longitudinally inward and thence transversely outward therethrough for the purpose of admitting oil to lubricate the same.

C is the crank-chamber of the engine and is provided with steam-ports O O2 O3 C* and is fast mounted on the driving-shaft B and loose mounted on the crank-shaft B.

D D2 D3D4 are cylinders having steam-ducts Z Z2 Z3 d* therein communicating with the interiors thereof and connecting with the inner ends of the ports O O2 O3 OA1 in the crankchamber O and radially secured by their inner ends to the sides of and opening into the crank-chamber O and closed at their outer ends by means of heads D5.

E E2 E3 Ei are pistons freely slidable in their respective cylinders D D2 D3 D".

F is a crank fast by one end thereof to the crank-shaft B and provided at its other or free end with a crank-pin F, Fig. 3.

G G2 Gr3 Gf are piston-rods pivoted by their inner ends to the crank-pin F of the crank F and by their outer ends to the wrist-pins g' gf g g" of the pistons.

H is a circular steam-chest having' a central circular openingI H, Fig'. 2, in the head H2 thereof, the circular projection H3 on the crank-chamber O entering and serving as a closure for its open and inner end H". The steam-chest H either rests on a separate stationary base (not shown) or may be connected with and form a part of the main frame A of the machine.

I is a pipe tapped in through the head H2 of the steam-chest H for the admission of steam thereinto.

J J' are an outlet-chamber and connected pipe for the escape of exhausted steam from the engine.

K, Fig. 5, is a circular valve having an inlet-port K and an outlet-port K2 therein, the former port, K, being so arranged as to successively register with the ports O O2 O3 Ol in the crank-chamber O and also being' in conimunication with the interior of the steamchest H, wherein such valve K is stationarily seated, and the latter port, K, opening into a radial chamber K3, which opens outward through the periphery of such valve K into the outlet-chamber J.

K'L represents packing-rings set into the periphery of the valve K to insure a tight joint between the same and the wall of the steamchest H.

Ki is a segmental recess in the face K6 of the valve K, through the bottom of which the inlet-port K extends.

L is a gate included and adapted to slide endwise in therecess K in the valve K, and thereby completely or partially close the inlet-port K therein, according as may be desired.

M, Figs. 2 and 4, is a bushing mounted in the circular bearing H- in the steam-chest H, so as to be rocked therein, anditself furnish- IOC ing a bearing for the crank-shaft B' and also being provided with a transverse downwardlyextending preferably integral arm M, made fast at its lower end to the gate L.

M2 is a lever fast by its lower end to the bushing M, which it serves to rock to and fro in its bearing H to operate the gate L, which regulates the amount of steam to be admitted through the inlet-port K or excludes it therefrom altogether, according as desired.

M3 is a spring-actuated detent mounted in the lever M2 and adapted to engage any of the sockets h i in the segmental plate M5 and therethrough lock its lever M2 and the gate L, connected intermediately therewith, in any desired positions.

MG is a hand-lever of the ordinary form for disengaging the detent M3 from the sockets IWIi to release the lever M2.

N is a worm-wheel fast mounted on the crank-shaft B.

N is a shaft mountedin the bearings N2 N3 on the frame A of the engine.

N2 is a worm meshing with the worm-wheel N and fast mounted on the shaft N'.

N 5 is a hand-wheel for operating the shaft N.

In Fig. 3 the parts of the engine are in proper positions, if steam be admitted thereinto, to cause the same to be rotated in the direction indicated by the arrow a. If the crank-shaft B be turned by rotating the handwheel N in the direction indicated by the arrow c until the crank-pin I", Fig. 3, occupies the position indicated by the dotted circle X, the engine will reverse its motion and rotate in the direction indicated by the arrow Supposing all parts of the engine to be in the positions shown in the drawings, its mode of operation will be as follows: Steam entering' the steam-chest H from the pipe I passes therefrom through the inlet-port K in the valve K and thence through the port C and duct (Z3, Fig. 2, into the cylinder D3, thereby causing the engine to turn about one-fourth of a revolution or until the inlet-port K in the valve K registers with the port C'L in the crank-chamber C, and so on, the port K' next successively registering with the ports C and C2 in the cylinders D D2. If the inlet-port K of the valve K is opened to its fullest eX- tent, it will continue to admit steam to the port it is leavingI after it has begun to register with and admit steam to the port it is approaching. Such adjustment of the gate L will obviously result in the generation of great power. When little power is required, the gate L should be so adjusted as to admit but little steam and that to but one port of the engine at a time.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
