FBANK MURGATROYD, OF CLEVELAND, OHIO.
IMPROVEMENT IN REVERSIBLE VALVES FOR STEAM-ENGINES.
Specification forming part of Letters Patent No. 178,870, dated June 20, 1876, application filed March 24, 1876.
- To all whom "it may concern:
This invention relates to reversing-valvesfor steam-engines; and consists of a pistonvalve arranged within a valve-case, having peculiar chambers and ports, and connected by a double pipe or pipes with the ordinary inlet and exhaust ports of valve-chests of two ordinary steam-engines, combined and operating as hereinafter described and claimed.
To enable others to fully understand my invention, I will proceed to describe the same in detail, with the aid of the accompanying drawing, in which- Figure 1 is a top or plan view, having the valve-case cut on line 4000 of Fig.3. Fig. 2 is a vertical section of the valve and case on line y y of Fig. 3. Fig. 3 is a side elevation, having the valve-case cut on the vertical section-line z z of Fig. 1. I
O 0 represent a double pipe or pipes, designed, as shown in the drawing, as a connection between the steam-chests of two engines. Midway between the ends of said pipes is attached a valve-case, D, in which are chambers A B S E, formed by partitions, through which are made openings 0 O, in which the valve V is operated by means of the lever L. S is a chamber in the top of the case D, where the steam is admitted, and open to the chambers A B. A B are passages leading to the The operation of this device is as follows:
With the valve V invthe' position seen in the drawing, steam would pass into passage B through the chamber B, thus leading'to one side of the engine-valves. By changing the valve V to the other end of the case, the steam is directed into passage A, leadin g to opposite side of engine-valves, thus reversing said engines.
Having described my invention, I claim The valve-oasin g D, having partitions therein, forming the inlet-chamber S, chambers A B, and exhaust-chamber E, intercommunicating by means of openings 0, and combined with the valve V, Working in said openings, the passages A B, double pipe 0, and steamchests of two engines, substantially as and for the purpose described.
