ROTARY ENGINE.
SPECIFICATION forming part of Letters Patent N 0. 542,920, dated July 16, 1895.
Application filed November 12, 1894. Serial No. 528,500. (No model.)
To aZZ whom it may concern.-
Be it known that I, DAVID BERRY, of Fish Rock, county of Mendocino, and State of California, have invented a new and Improved Rotary Engine, of which the following is a full, clear, and exact description.
The object of the invention is to provide a new and improved rotary engine which is comparatively simple and durable in construction, very effective in operation, and arranged to permit of conveniently reversing the engine whenever desired, and to utilize the motive agent to the fullest advantage.
The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then point;
ed out in the claims. Reference is to be had to the apcornpa-nying drawings, forming a part of 7th sspecification, f re fdrence indicate corresponding parts in all the views.
Figure l is afictional side elevation of the improvement. Fig. 2 is a transverse section of the same on the line 2 2 of Fig. 1. Fig.3 is a sectional side elevation of part of the improvement with the reversing-valve in a different position. Fig. 4. is a sectional plan view of the reversing-valve on the line 4 4 of Fig. 2, and Fig. 5 is a sectional side elevation of a modified form of the abutment and piston.
The improved rotary engine is provided with a cylinder A, in the head of which is mounted the shaft B, carrying atits outer ends a fiy-wheel B and a pulley B for transmitting of the shaft to other machinery. On the shaft B, within the cylinder A, is secured a wheel 0, provided with a number of pistons D D,fitted to slide radially in the said wheel to engage the sides between the rim of the wheel and the rim of the cylinder A, as is plainly shown in Figs. 1 and 2.
The pistons D D are forcedinto their outermost position by springs E, as indicated in Fig. 1, so thatthe pistons D D in passing over the permanent abutment A, projecting into the sides between the wheel and cylinder, can slide inwardly, owing to the yielding of the springs E. The abutment A is pro vided with a spring-pressed packing-belt F engaging the periphery of the wheel 0, so as to form a steam-tight joint between the rim of the wheel and the abutment.
From the sides of the abutment A lead the ports a and b to the ports c and d, respectively, formed in the opposite sides of a valve G, mounted to slide transversely in the base of the cylinder A, as is'plainly shown in the drawings. The ports 0 and d are adapted to connect with the ports e and f, arranged in the base of the cylinder A and leading from the inlet-pipe H to the exhaust-pipe HQrespectively, of which th efofmer is connected with a suitable source ofs'team-supply, so that live steam from the boiler or other supply can pass through the ports 0 and a into t'h e cyli'iider A on the left-hand side of the "abutment A to press on the piston D, so as to turn the wheel 0, and consequently the shaft B in the direction of the arrow at. The steam in front of the other piston D is forced through the ports I) and d into the exhaustpipe H to the outer air, a condenser, or other device.
In order to reverse the engine, I provide the valve G with the two diagonally-arranged ports g and h, of which the port 9 is adapted to connect the port e with the port b, and the other port h is adapted to connect the port f' with the port a, so that the motive agent entering the pipe H can pass through the ports e, g, and b into the cylinder A at the'right hand of the abutment A to press on the piston D, so as to rotate the wheel 0 and shaft B in the inverse direction of the arrow at. The steam in front of the other piston D now passes through the port a, the port h, and port f into the exhaust-pipe H, and from the latter to the outer air. It is understood that the slide-valve G is shifted transversely to connect the said ports 0 d and g h with the ports in the cylinder above described, to cause the engine to runin either direction.
As shown in Fig. 2, one outer end of the valve G is connected with a bell-crank lever I, under the control of the engineer, to permit the latter to shift the valve G transversely to bring either set of ports arranged in the valve into action.
As shown in Fig. 5, the abutment J for the cylinder A is mounted yieldingly in a recess in the cylinder and is pressed on by a spring J, so as to hold the said abutment normally in the path of the piston K, mounted yieldingly on the springs K in the wheel 0 held on the driving-shaft B. 'lhepiston and abut' ment J and K are preferably made wedgeshaped in cross-section, as illustrated in Fig. 5, so that both yield when the two surfaces of the abutment and piston come in contact with each other on the rotation of the Wheel C. The springs J and K press the abutment and piston back into their former position as soon as the two parts have passed each other.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- I 1. In a rotary engine, the combination with a cylinder having an abutment and provided with a port on each side of the abutment and with ports in its base, and a wheel mounted in the cylinder and provided with yielding pistons, of a slide valve below the abutment, and provided with ports in its sides and with diagonally arranged ports in rear of the side ports and extending through the valve in opposite directions, substantially as described.
2. In a rotary engine, the combination with a cylinder having an abutment and provided with the ports a 1) leading from opposite sides of the abutment and with the ports efin its base, and a Wheel mounted in the cylinder and provided with yielding pistons, of the slide valve G mounted in the base of the cylinder and provided with the ports a d for connectiug the ports ef with ports a, b, and with the diagonally arranged ports 9 h extending through the valve, the port 9 adapted to connect port c with port b, and port It, the portf with port a, substantially as herein shown and described.
DAVID BERRY.
