OSCILLATI NG VALVE.
SPECIFICATION forming part of Letters Patent No. 728,787, dated May 19, 1903.
Application filed December 30, 1902. Serial No. 137,152. (No model.)
To all whom it may concern: Be it known that I, GEORGE LESLEY WACK EROW, residing at Mellette, in the county of Spink and State of South Dakota, have invented certain new and useful Improvements in,
Oscillating Valves, of which the following is a specification.
This invention relates to oscillating valves; and the invention consists of novel and useful improvements providing increased advantage over similar valves as heretofore constructed.
More definitely stated/the invention consists of a peculiar oscillating valve extending from end to end of the cylinder and a special steam-chest and arrangement of steam passages or ports.
In order to enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation with reference to the accompanying drawings, forming a part of this specification, and in which- Figure l is a view in side elevation, illustrating my invention, the detachable side of the steam-chest being removed and the enginecylinder shown in section. Fig. 2 is a transverse vertical section through my invention, taken on line a: w of Fig. 1. Fig.3 is a perspective view of an engine-cylinder and my improved valve-seat.
In carrying out my invention I employ a steam-chest A, consisting of a special valveseat B and an upper portion preferably formed in two pieces-namely, a removable side plate 0 and a one-piece top and side D D. The valve-seat B, side plate 0, and the one-piece top and side D D are provided with boltholes and flanged edges, (shown in the drawings,) adapting them to be secured together.
The valve-seat B consists of an elongated plate B, having vertically-disposed ends E. The inner side of the ends E is curved, as at F, and provided with ports F F, the former being the inlet leading to the engine-cylinder and the latter the exhaust-ports having outlets F, that may be opened and closed, as will be understood, by any suitable mechanism, also well understood, in operative connection with the engine.
In further carrying out my invention I employ a peculiar valve G, fixed to a'rock-shaft H, supported by and passing through one or both of the side plates 0 D of the chest A. My valve G is made hollow, providing a passage G through it from end to end, as shown. The rock-shaft H may be worked by wellknown mechanism and is obviously provided with suitable stuffing-boxes and bearing in the sides of the chest.
It Will be seen that my valve G extends from end to end of the valve-chest and has its ends seated at all times steam-tight by suitable packing, on projected detail view, upon the inner surfacesF, adapted to form communication With the exhaust-ports F at both ends of the valve-chest and upon oscillation cover and uncover the feed-ports, as will appear farther on.
I would have it understood that my invention comprehends either forming the whole valve-seat B in one piece with the engine-cylinder or separate therefrom; also, that the top D and side D of the valve-chest may consist of separate pieces or be formed integral, as found desirable. It will be further noticed by reference to Fig. 30f the drawings that my valve G does not extend completely across from side to side of the steam-chest. With such construction free passage of steam is permitted around and under the valve, thereby insuring perfect balance.
With the parts above described and a steam inlet I the operation of my improved oscillating valve is as follows: When the piston J is at the forward end of the engine-cylinder, as indicated in Fig. 1, the valve G will be in position with its passage-Way G connecting both exhaust-ports F and the feed-.port F at the far end of the cylinder from this position of the piston. In this position of the piston J and upon return stroke thereof, as indicated by the arrow in, Fig. 1, steam will feed direct from the steam-chest A, through the uncovered port F in rear of the piston, and exhaust through the far port F and both ports F At proper time the valve will be oscillated, uncovering the feed-port F at the rear end of the cylinder, by valve-shifting mechanism well understood, with its passagewith steam exhausting through the outlets of the cylinder with its passage-way at each way G still forming communication between the ports F at both ends of the cylinder, and also covering the port F at the forward end of the cylinder, as indicated by its dotted position. In this position of the parts the port F at the rear end of the cylinder will be uncovered, adapted to feed steam from the chest A direct to rear of the piston, and the valve G be in position covering the port F at the forward end of the cylinder, and both ports F F and so on to continue at each reciprocation of the piston and oscillation of the valve while the engine is in motion.
From the above description it is apparent that I provide a valve extending to each end with one set at each end of the said cylinder, and one port in each set adapted to feed and the other adapted to exhaust, an oscillating valve located within the steam-chest, having a passage-way through it from end to end providing communication between the exhaust-ports of each set and one feed-port, substantially as described.
2. In combination with an engine-cylinder and its steam-chest, feed and exhaust ports at each end of the cylinder, means adapted to put one feed-port in communication with both exhaust-ports, the said means consistin g of an oscillating valve extending from end to end of the steam-chest, and having a passage-way lengthwise through it, substantially as described.
3. In combination with an engine-cylinder, and its steam -chest, the latter having two valve-seats, one at each end thereof, exhaust and feed ports in each valve-seat, an oscillating valve in said chest, extending from one valve-seat to the other and having a passage-way through it adapted to put in communication both exhaust-ports and one feedport, and means adapted to oscillate said valve, substantially as described.
