To aZZ whom it may concern.-
Be it known that I, ALEXANDER H. GOULD, a citizen of the United States, residing at T0 ledo, in the county of Lucas and State of Ohio, have invented new and useful 1111-. provements in Rotary Engines, of which the following is a specification.
My invention relates to improvements in rotary engines, and pertains to that type of engines which includes a revolving mandrel or armature carrying a plurality of pistons which through the medium of piston-rods act upon an inclined surface for revolving the mandrel or armature, all of which will be fully described hereinafter, and particularly pointed out in the claims.
In the accompanying drawings, Figure l is an interior side elevation of the mechanism constituting my invention, the casing being shown in section. Fig. 2 is a transverse sectional View on the line 2 2 of Fig. 1. Fig, 3 is a longitudinal vertical central sectional view of Fig. 1. Fig. 4 is a detached side elevation of the mandrel or armature and its shaft. Fig. 5 is an end elevation of Fig. .4. Fig. 6 is an interior end elevation of one of the revolving rings, the piston-securing band being shown in position thereon. Fig. 7 is a similar view to Fig. 6 with the piston-holding band removed. Fig. 8 is a detached view of one of the pistons, showing the manner of connecting the pitman thereto.
Referring now to the drawings, A is a cylindrical casing in which is situated a revoluble armature or mandrel B. This mandrel or armature B is provided with a plurality of longitudinally-extending recesses or grooves O in its periphery, which recesses or grooves constitute piston-receiving cylinders, as will be more fully explained hereinafter. The
periphery of this mandrel or armature B fits snugly the inner surface of the sides of the cylinder, A, thesaid cylinder sides constituting the outer wall of the said grooves,
thus providing a plurality of inclosed l0ngitudinally-extending grooves O, which, as before stated, constitute piston-receiving cylinders. Situated in each of these piston-receiving grooves O are two pistons D, the said pistons being independent of each other for the purpose of being forced in opposite directions by the introduction of steam between them. The mandrel or armature B is provided with a concentric longitudinally-extending shaft E, which has its end journaled j in suitable bearings F at the ends of the cylinder A.
Situated within the cylinder A at its ends are the inclined surfaces G, and these surfaces are rigidly supported or connected in any desired manner with the said cylinder. Situated justinside of these inclined surfaces G are the revoluble and oscillating or wabbling disks H, the outer surfaces or sides of the said disks being provided with concaved annular ball-receiving grooves a, which register with correspondingly-arranged ball-receiving grooves b, formed in the inclined surfaces G. Placed within these ball-receiving grooves are a plurality of balls 0 and which constitute the ball-bearing between the revoluble and oscillating disks H and the inclined surfaces G, as will be readily understood. The innersurfaces of these revolv- 2 ing disks H are provided with a circular groove I, which is adapted to receive the inner ball-shaped ends I) of the pitman J, and the inner ball-shaped ends of the pitmen are secured in position by means of a ring K, which is provided with a plurality of openings e, which register with the recess formed in the inner face of .the revolving disk H and larger in diameter than the adjacent pistons, the said plate M and the pistons being provided with recesses corresponding to the shape of the end of the pitman sufficiently larger to permit a relative oscillation or free movement of the parts.
The shaft E is provided with a collar N of any suitable construction, and this collar N is provided with a plurality of outwardlyprojecting pins P, which are adapted to enter the radially-arranged slots Q, formed in the inner faces of the revolving disks H in their center. These pins and collars serve to lock or holdthe armature or mandrel B (through the intervention of the collarN and the shaft) against independent revolution, whereby...
when one is rotated the other is correspondingly rotated or revolved. 1 By reference to Fig. 2 it willbe seen that thecenter of the cylinder or casing A is provided with a steam-inlet port R,.which ex piston-receiving grooves at a point slightly above the lower side of the armature or man dr'el B, and consequently admits steam be .tween the piston=heads just as the pistons are traveling up the inclined surface of the end T pieces G through the medium of the revolw ing disk H, to which the outer ends of the pitinan are attached. The op osite side of the cylinder A is provided with an exhaust port S, which extends nearly half-way around the cylinder, and consequently nearly half way around the armature or mandrel B, and
this exhaust-port S is in communication with the piston-receiving grooves at a point between their inner ends, the said exhaust pcrt S having an outlet t for the outward passage of the steam.
In operationsteam is admitted through the inlet-port t and being continuously fed be-;
tween the pistoneheads within thepistom grooves as the armature revolves in the die rection indicated by arrow in Fig. 2 tending to force the said'piston apart, and their pit men are forced against the revolving oscillatingydisks H,:causing them to revolve, OW:
ing to their inc1ination, and in turn thedisks cause the revolution of the armature or man-f dr'el B through the medium Of its shaft and the pins P. When the pistons have reached the inner end ofthe steaimport R, then from that point on the expansio of the steam is used in the said piston-receiving grooves until the piston reaches a point directly above the center of the axes of the armature, at which point the said groove is placed in communication with the exhaust-port S and permits the escape of the steam. The pistons are brought continuously and consecutively in communication with the teamsinl'et port R and consecutively carried in communication with the exhaust-port S before they begin to travel down the incline.
By means of an engine constructed as herein shown and described I am able to utilize the full power of the steam in, a plurality of cylinders and to also use the expansion power of the steam, which will be regulated, as will be readily understood, by the steam-receiving port.
length of the 1 I do not here show any throttle or valve in communication with the steam receiving opening 2', communicating with thesteamportmR; but it will be readily understood that any desired form of throttle or valve will be situated in the communication between this opening '5 and the source of steam for the purpose of regulating the speed of the engine. Having thus described my invention, what I claim, and desire to secure by Letters Pat- 1.
