ROTARY ENGINE.
SPECIFICATION forming part of Letters Patent No. 660,675, dated. October 30, 1900. Application filed February 12, 1900- Serial No. 4,917. (No model.)
To all whom it may concern:
Be it known that I, CHARLES I. WILLIAMS, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Rotary Engines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates to improvements in rotary engines, and possesses the useful and novel features hereinafter described and claimed.
The object of my invention is to provide a successful rotary engine that may be operated by any of the well-known powers-such as steam, compressed air, gas, or gasolene and in which the force is applied directly to the piston-wheel at or near the outer circumference.
In a detailed description of the invention reference is made to the accompanying drawings, of which- Figure 1 is a side sectional elevation of my improved rotary engine with the outer casing removed. Fig. 2 is a transverse or vertical section of the same.
In the following specification similar reference-letters indicate corresponding parts in the drawings.
A designates the base of the engine, and B is a semicylindrical casing secured thereto, the two forming a chamber in which is mounted a piston-wheel O on shaft D, the position of the shaft, and likewise the axis of the piston-wheel, being eccentric to the center of the chamber. The periphery of the piston wheel is provided with a series of cams E, the number of which may be varied according to the These cams control the admission-valve G, which is normally pressed against said cams by means of a coil-spring c. A series of pistons or flanges F are carried on the piston-wheel at points adjacent to the highest parts of the cams. These pistons are bifurcated at their connecting ends to provide two projecting portions, which extend on each side of the wheel 0, and said pistons F are made adjustable in and out from the axis of the wheel by means ofset-screws ct, such adjustment being necessary in order that the pistons may be in proper contact with the bottom of the air-tight chamber H when passing therethrough. The said air-tight chamber H is formed in the base, but may be formed elsewhere within the casing. As is shown in the drawings, this chamber has adjustable side walls J, which. may be adjusted to snugly fit the sides of the pistons by means of set-screws b. This air-tight chamber occupies a portion of the circumference of the piston-Wheel and extends from a suitable point above or beyond the inlet-passage e to the exhaust-passage d. The power enters the port f, and when the valve G is in a position with its port 1 registering with the passage e the power passes into the air-tight chamber H and, coming in contact successively with each of the flanges F, causes a rotation of the cam-wheel and shaft. As the gradually-increasing surface of each of the cams E rides against the inner end of the admission-valve G the power is momentarily shut off from the passage 6, during which time the chamber I-I exhausts through passage d, and as the lower surface of the next following cam approaches the valve G said valve is permitted to move in under the pressure of spring 0, at which time the portt' therein registers with the passage 6. valve G is held against the cams E at all times by the spring 0 and forms a wall closing the end of the air-tight chamber H and receives all the back pressure, so that the power is enabled to exert its full force on the pistons to drive the wheel in the direction indicated by the arrows. This feature of the valve forming an inclosing Wall for the end of the chamber is an important feature of my invention.
It will be observed that the cams or flanges E and cam-wheel O are onlyin frictional contact with other parts while they are passing through the air-tight chamber H and that said chamber I-I approximates only about one third of the circumference of the cam-wheel. It will therefore be seen that the friction is reduced to a minimum. Ihave shown the The side Walls .I of the air-tight chamber H as adjustable. The pistons F may also be made non-adjustable.
Having described my invention, I claim.
1. In a rotary engine, the combination of a piston-wheel having cams, an inlet-valve controlled by said cams, an air-tight chamber Withinthe casing, and pistons or flanges car- Tied by said piston-wheel and which receive the pressure as they enter said air-tight chamber, said pistons or flanges projecting over the sides of the piston-wheels, and means for adjusting the said pistons or flanges, substantially as specified.
2. In a rotary engine, the combination with a casing, and an air-tight chamber formed therein, ofa piston-Wheel, cams on said wheel, an inlet-valve operated by said cams to admit pressure to said air-tight chamber, and pistons or flanges carried by said wheel, said pistons 01' flanges having extensions which project on each side of the piston-wheel, and the said pistons and wheel adapted to form air-tight inclosures for said chamber and the pistons receiving pressure from the admission-valve as theyenter said chamber and means for adj ustingthe positions of said pis tight chamber and forming a wall for one end of the air-tight chamber, cams on the pistonwheel controlling the position of said valve, and pistons carried on said wheel and receiving pressure as they enter the air-chamber said pistons having bifurcations or extensions which project on each side of the wheel, and means for adjusting said pistons, substantially as described.
In testimony whereof I aflix my signature in presence of two witnesses.
CHARLES I. WILLIAMS.
