JACOB IV. DAVIS, OF ANDERSON, INDIANA.
REVERSIBLE ROTARY ENGINE.
SPECIFICATION forming part of Letters Patent No. 782,175, dated February 7, 1905.
Application filed April 1, 1904. Serial No. 201,113.
To a]! whom it may concern.-
Be it known that I, JACOB BEDDING, a citizen of the United States, and a resident of Carthage, in the county of Bush and State of Indiana, have made a certain new and useful Invention in Reversible Rotary Engines; and I declare the following to be a full, clear. and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being bad to the accoml'mnying (.lrawings, and to letters and figures of reference marked thereon, which form a part of this specification.
Figure I is a side elevation of my invention. Fig. 2 is a section on the line 2 2, Fig. I. Fig. 3 is a section on the line 3 3, Fig. 2.
The invention has relation to rotary engines; and it consists in the novel construction and combinations of parts, as hereinafter set forth.
In the accompanying drawings, illustrating the invention, the letter a designates the case, in which are inclosed the working parts of the engine.
2 represents a lower cylinder-chamber communicating with an upper cylinder-chamber 3.
6 represents the rotary piston-body in the lower cylinder-chamber, having the transverse flange or projection rib t, which is channeled to receive the piston-plate 5, which is movable outward, so that when the piston is in rotation this piston-plate will be moved outward by the centrifugal action against the wall of the lower chamber 2 with suflicient pressure to prevent leakage of steam. The shaft of this piston has its bearings in the side walls of the case and is provided with a spline ll, whereby it engages a channel of the central opening T of the piston-body, so that this piston-shaft will have freedom for transverse movement in either direction through the piston. This shaft is provided with a disk 1 carrying at one point an antifriction-roller f, adapted to engage a yoke e, which is rigidly attached to a journal 8 of the hollow valve and whereby the valve is held in position in a yielding manner to allow the passage of the piston-rib and plate, as indicated at m.
0 indicates thehollow valve, which is of convex cylindrical form on its upper surface and of concave cylindrical form on its lower surface, as indicated at n, the upper portion and the lower portion being separated by the short concave corner-bearings n, which are of the same curvature as that of the cylindrical piston-body 7), which is (lBSlg'IlCtl to be engaged by one or the other of these bearings, according to the direction in which the engine is worhingthat is to say, whether forward or reversed. An opening s in the top of the valve serves to admit steam into the chamber of this valve, which is of considerable size,being designed to hold enough steam to effect one rotation of the piston-body. At about ninety degrees distance from the steam-inlet are the discharge-opcnings f 2, through which when the valve is turned to proper position the steam from the valve-chamber is discharged into the piston-chamber to act on the piston. In this position when the valve is just turning to allow the piston-plate to pass by its bearing the position of the valve is changed, bringing its inletbpening opposite to the steam-inlet or throttle 9 of the incasement, which is provided with a cock rlto control the steam. The valve is thusin position when the cock is open to take steam just in time to discharge the same into the pistonchamber as the valve resumes its position with its bearing against the piston body or drum. In this operation the disk r with its antifriction-roller f, assists by the engagement of the roller with the yoke in such wise as to aid in lifting the bearing end of the valve against the resistance of the spring.
Suitable packings are provided in bearings of the casing to avoid leakage in the chambers of the casing.
The engine is designed to be readily reversible, and it is susceptible of being driven by the action of compressed air or gas as well as by steam.
Having described this invention, what I claim, and desire to secure by Letters Patent, is
1. In a rotary engine,the combination with a casing, of a rotary piston, a movable pistonplate and a hollow concavo-convex pivoted valve having concave corner-bearings,and inlet and discharge openings, substantially as specified.
2. In a rotary engine, the combination with a casing having a regulating-valve in its steampassage, of a rotary piston,and a hollow concavo-conveX pivoted valve having concave corner-bearings,and inlet and discharge openings, substantially as specified.
3. In a rotary engine,the combination with a casing, of a rotary piston, an endwise-movable piston-shaft, a piston-plate, a channeled bearing of said piston for said piston-plate, and a hollow concavo-convex pivoted valve JACOB BEDDING.
