ROTARY ENGINE.
SPECIFICATION forming part of Letters Patent N 0. 774,551, dated November 8, 1904. Application filed June 27, 1904. Serial No. 21%307. (No model.)
To all whom/ it puny concern.-
Be it known that 1, WILLIAM BEAUMONT, a citizen of the United States, and a resident of Granite, in the county of Greer and Territory of Oklahoma, have invented a new and Improved Rotary Engine, of which the following is a full, clear, and exact description.
This invention relates to improvements in rotary engines, an object being to provide an engine of this type so constructed as to be evenly balanced while running andwhich may be operated with an economical use of steam.
Further objects of the invention will appear in the general description.
I will describe a rotary engine embodying my invention and then point out the novel features in the appended claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.
Figure 1 is a plan view, partly in section, of a rotary engine embodying my invention. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a section on the line 3 3 of Fig. 1. Fig. tis
. a detail view of a valve mechanism employed.
Figs. 5 and 6 are views, one in perspective and the other in side elevation, of portions of the valve mechanism; and Figs. 7 and 8 are transverse sections of the valve mechanism, showing the parts in different posit-ions.
Referring to the drawings, 5 designates a cylinder in which a piston-like disk 6 is mountcd to rotate, and supported on the cylinder 5 is an abutment-cylinder 7. This cylinder 7 communicates with the cylinder 5,and through an openingforming this communication a portion of the abutment-disk 8 extends. It will be noted that the piston and abutment-disk have their planes arranged at right angles to each other. The piston-disk 6 is somewhat smaller than the interior of the cylinder 5, so as to form a steam-chamber around the piston -disl:. It is provided, however, at one point with a piston-wing 9, which engages closely against the interior of the cylinder.
Seated in interior channels formed in the walls of the piston cylinder and engaging with the sides of the piston-disk 6 are tubuagainst the piston.
lar packing-rings 10, and steam is admitted to the rearsides of these rings through ports 11, so as to press the rings sufficiently tight It will be noted that the piston-disk is transversely curved, so as to correspond with the peripheral curvature of the abutment-disk, and the abutment-disk at one point is provided with an opening 12, which when coincident with the wing 9 will permit the wing to pass. Then by continued movement of the abutment-disk its periphery will be engaged by the periphery of the piston-disk until the opening 12 and the wing 9 are again coincident.
Formed in the walls of the-cylinder 7 at opposite sides of the abutment-disk are steamchambers' 13, to which steam is admitted through a port 1 1, the chambers of a side communicating through a port 13. Each pair of chambers 13 has an'area equal to the area of the wing 9, so that the pressure of steam in the chamber at the opposite side of the piston-wing in which the piston is rotated will'balance the pressure practically to force the abutment-disk toward the line of movement of the wing, and therefore relieve it somewhat of frictional engagement with the wall of the cylinder.
Secured to the front side of the cylinder 5 is a casing 15, at one end of which is a steamchest 16, receiving steam through a pipe 17. Fixedly secured in the casing 15 is a valveseat 18, having at its inner enda longitudinal and tapered opening to receive a correspondingly-shaped tubular valve 19. This valve has ports 20, providing communication between its interior and the steam-chest 16,
and extended outward from the valve, through a stuffing-box 21, is a stem 22, having on its outer end a gear-wheel 23, meshing with a gear-wheel 24, which in turn engages with a gear-wheel 25, mounted on a counter-shaft 26, on the inner end of which is a bevel-pinion 27 for engaging with a bevel-pinion 28 on the shaft of the abutment-disk 8, the said shaft having a bearing. in a block 28, adjustable vertically by means of a screw 28 This gear-wheel 2& also engages with a gear-wheel By this 29 on the shaft of the piston-disk 6.
system of gearing the several rotary parts will be properly timed to perform their different functions.
For the purpose of adjusting the valve 19 to compensate for wear I employ a screw 30, which passes longitudinally through the valve seat 18 and engages with the inner end of the 3 valve. By manipulating the screw 30 and the stem 22 the valve may be quickly adl justed. Mounted to move longitudinally on 1 the valve-seat 18 is a regulating-sleeve 31. This sleeve is provided with a longitudinal interior channel 32, which receives a rib 33 on the exterior of the valve-seat, which permits the regulating-sleeve to move longitudinally, as before mentioned, but will prevent rotary movement thereof. The valve-seat 18 has a port 3 1, which extends partially around it, and on opposite sides of a bridge piece or 5 block 35, which form the end walls of the l port 34, stop-blocks 36 37 are movable. The stop-bloclrs have outwardly-extended pins or lugs which engage in channels 34:, formed in the interior of the sleeve 31. For a portion of their length at opposite sides the channels 3st have straight walls or walls parallel with the axis of the sleeve. The other portions, however, have a spiral trend, so that when these spiral portions engage with the lugs of the blocks 36 one of said blocks will be moved around the port 34:, so that steam may pass through a port 39, formed in the valve into said port Set. It will be understood that only one block 36 or 37 is to be moved-that is, depending upon the direction in which the engine is running. In Fig. 7 the blocks are in such a position as to permit a practically full head of steam to pass into the engine. In Fig. 8, however, the block 36 is shown as turned to a position so that steam will be admitted to the engine only until the port 39 shall have reached the block 36.
The sleeve 31 is provided with a port 40, and steam passing through this port 40 into a steam-chamber 11 in the casing 15 will pass through either one of the ports 42 43, which lead into the cylinder 5 at opposite sides of the piston-wing 9. As steam passes through the port 42, for instance, it will rotate the piston in one direction and the exhaust will pass out through the port 13.
As a means for shifting the sleeve 31 I employ a lever 44:, arranged at one end of the casing 15 and having a rod connection A5 with the sleeve. The lever may be held as adjusted by any suitable rack mechanism.
As a means for changing the direction of rotation of the engine I employ a slide-valve 16, movable in a slideway 47 forward of the ports A2 A3, and this slide-valve has a port 48 designed to direct steam from the chamber 11 into the port 42, and it also has a port 4:9 for directing steam into the port 43. The slidevalve is also provided adjacent to the ports 48 4:9 with exhaust-ports 50 51, designed, re-
spectively, to be placed in communication with the ports 42 4:3. As the valve is located in i Fig. 1, live steam will pass through the port A2 and exhaust will take place through the port 13. The reversing-valve is shifted by means of a lever 52, having a rod connection 53 with the valve.
It will be noted that the body of the engine is cast in four parts, A B O D, suitably bolted together, and is therefore comparatively cheap to manufacture and assemble and is easily trued or turned up. In other words, the body of the engine is cast in four vertically-divided parts, so that the cylinder-cavity may be first bored out, while the parts C D are bolted together until the cavity is true, then taken apart, and the other parts, A B, are similarly treated for the reception of the abutment-disk. This I consider important, as it is very difficult to secure proper adjustment in any other way.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A rotary engine comprising a pistondisk cylinder having interior annular channels, tubular packingrings in said channels, steam-ports leading to the rear sides of the rings, and a piston-disk mounted to rotate in the cylinder and against the sides of which said rings press.
2. A rotary engine comprising a pistondisk cylinder, an abutment-cylinder arranged on the piston-cylinder at right angles thereto, a piston mounted to rotate in the pistoncylinder, an abutment-disk mounted to rotate in the abutmcut-cylinder, the interior walls of said abutment-cylinder being provided with chambers at the opposite sides of the abutment-disk for receiving steam, and means for causing the abutment-disk and piston-disk to rotate in unison.
3. A rotary engine comprising a pistondisk cylinder, an abutment-cylinder mounted on the piston-disk cylinder at right angles thereto, a piston-disk mounted to rotate in the piston-disk cylinder and of smaller diameter than the interior of the cylinder, a pistonwing carried by the disk for engaging with the inner annular wall of the cylinder, an abutment-disk mounted to rotate in the abutmentcylinder and having an opening at its edge through which said piston-wing may pass, and. steam-receiving chambers formed in the walls of the abutment-disk cylinder at opposite sides of said disk, the area of each chamher being equal to the area of the piston-wing.
1. In a rotary engine, a rotary piston, an abutment therefor, a valve-seat having a tapered longitudinal opening, acasing in which said valve-seat is fixedly arranged, said valveseat having a port extended partially around it, a ported valve operating in the valve-seat, blocks movable in said port of the valve-seat, and a regulating-sleeve mounted to move longitudinally on the valve-seat and having means ment thereon, and channels in the interior of said sleeve for receiving projections on the blocks to cause the movements of the blocks circumferentially of the valve-seat, certain portions of said channels in the sleeve being spirally disposed.
