ZAOHARY TAYLOR RENO, OF NEW ORLEANS, LOUISIANA, ASSIGNOR ONE-HALF TO DAVID GREER MOOAN, OF SAME PLACE.
SLIDE- SPBCIPICATION forming part of Letters Patent No. 342,633, dated May 25,1886.
Application filed October 3, 1885. Serial No. 178,945. (No model.)
To aZZ whom it may concern.-
Be it known that I, ZAOHARY TAYLOR REr'o, a citizen of the United States, residing at. New Orleans, in the parish of Orleans and State of Louisiana, have invented anew and useful Improvement in Slide-Valves for Steam-Engines, of which the following is a specification.
My invention relates to a balanced slidevalve that is arranged to have steam-pressure applied both above and below, and to work in the atmosphere without being incased in a steam-chest.
The invention consists in the construction and combination of parts, as hereinafter set forth.
Figure 1 is a longitudinal section of the balanced-valve mechanism and the cylinder and piston of a steam-engine. Fig. 2 is a longitudinal section of my valve with part of the steam-cylinder of engine and mechanism for reducing friction. Fig. 3 is a plan of the valve-seat of a steam-engine cylinder as adapted to my valve. Fig. 4 is a face view of the under side of the valve.
Similar letters refer to similar parts in all the views.
The course of the steam is shown by the arrows. The steam, as indicated in the drawings, enters at A, Fig. 1. It passes up under the valve B at O; thence along the steam-paspage D into the cylinder E. The exhauststeam passes out through passage F into ex.- haust-passage G; thence through hole H in valve B, down through hole Iin valve-seat, Fig. 3 to exhaustpipe J, opposite steampipe A, Fig. 3. WVhen the piston K has reached the end of the stroke and returns, the operation of the valve B reverses and the return-stroke is made, and so on.
At L, Fig. 1, is another steam-pipe, admitting steam to a small steam-cylinder, M. In this is a steam-tight piston, N.
At Ois a hole, through which the steam enters and presses on top of the valve B. The area of the space inside the piston N, where the steam presses on top of the valve B, must be equal to the area of the space at Oon the under side of the valve B, so that a perfect balance is effected, or nearly so. The differ- I ence of the areas of the steamcylinder M and the area of the inside of the piston N causes the steam-pressure on that difference to keep thejoint steam-tight at I. The valve B has faced seats top and bottom. The valve-seat Q and bottom of piston being also faced, no steam can escape to the atmosphere.
At Fig. 2 the piston Nhasasolid top, and is provided with packing-rings It, as shown at S, Fig. 1.
At T are rollers to diminish friction, working on upper face of the valve B, and holding it to its seat.
L is the steam-pipe that admits steam to the cylinder M.
The operation of the steam is otherwise the same as described for Fig. 1.
In Figs. 1 and 2, Uare standards to hold up cylinder M. V is the valve-stem; W, Fig. 1, the piston-rod, and E the engine-cylinder. X are ledges, between which the valve B works, acting as guides. It is obvious that the arrangement may also be reversed, the steam valve B, and the exhaust passing into the central opening. In that case the steam would enter pipe J, and exhaust through pipe A.
WVh-at I claim, and desire to secure by Let ters Patent, is
1. The combination, with an engine-cylinder and its slidevalve, of a frame secured to the outer side of the enginecylinder, a cylinder supported in said frame, and having a steam-inlet, and a steanrtight piston inclosed outside of the slide-valve, substantially as described.
2. The combination of an engine-cylinder, aslide-valve therefor, said valve having steampressure below and above, and working in the atmosphere without being inclosed in a steamchest, and a steam-tight piston incased in a steam-cylinder and adapted to bear on the outside of said slide-valve, substantially as described.
3. The combination of the cylinder E, having ports AD and F J, the slidevalve B, having ports 0 G H, the cylinder M, having steaminlet L, and the piston N, incascd in said cylbeing admitted into the outer openings of the in said cylinder, and having a bearing on the inder, and having a bearing on the outside of vided with rollers T, having a bearing on the the slide-valve, substantially as described; I slide-valve, substantially as described. 4. Thecombination with the engine-cylin- 1 l I der Eybaving ports A D and F J, and the ZAGHARY TAX LOB RENO 5 slide-valve B, having ports 0 G H, of the cyl- \Vitnesses:
inder M, having a steam-inlet at one end, and FREDERIC COOK,
the piston N, incased in said cylinder and pro W. H. COOK.
