uinPRovElvlENT |N VALVES Fou STEAM-ENGINES.
`To all whom t may concern:
Beit known that We, JOSEPH L. HARLEY, of
Baltimore, in the county of Baltimore and State l ofMaryland, an d'XAVER FENDRIGH, of Georgetown, in the District of Columbia, have inf "1 vented certain new and useful Improvements in Valves for Steam-Engines; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings,
making a part of this specification, in Which- Y Ijgigure 1 represents a top plan of the steamchest arranged upon the steam-cylinder and the valve in said chest. Fig. 2 represents a i longitudinal vertical section through the steaml chest and slide-valve therein Fig. 3 representsa vertical transverse section through the same. Fig. 4 represents a perspective view of the valve` removed from the steam-chest, i and Fig. 5 represents a modification thereof.
Similar letters of reference, where they ocl cur in the several separate drawings, denote y like parts in all of the figures.
Our invention relates, iirst, to allowing the end of the valve-rod to play in a steam chamber, t', communicatingwith the steam-chest, so that the pressure shall be 'equal upon it at al1 times; second, to `an inside jacket with the exhaust-port passing through it and out of the f 1 bottom or ends ot' the steam-chest, and also to t protect the valve from the vpressure of the live steam 7 upon its outer side and of' the exhaust-steam from its inner side; third, to the V f exhausting of the steam through either the cylinder or through the chest, or through both at the same time, and so preventing its pressure upon the inside of the valve. i To enable others skilled in the art tomake and use our invention, We will proceed to describe the same with reference to the drawings.
The steam-chest A may be arranged upon the cylinder B in any of the usual Well-known ways. Within the chest A the valve C is arranged so as to be moved over or past the in- 4let-ports a a to close and disclose them. The
exhaust-opening is at b, and the exhaust may pass out through the cylinder or through the steam-chest, as will be explained.
The `valve G, as more distinctly seen in Figs.
. .i 4, and 5, is of rectangular form and open both4 at its top and bottom. The valve stem or rod c, I prefer to unite with the valve, as shown in Fig. 4-tl1at is, to pass entirely through the valve-and thevalve maybe adjusted thereto by means o'thcset-nuts 1 l, this being the more reliable fastening; but the valve-rod may be out or divided and united to the valve, as seen in Fig. 5, if that plan be preferred. One end of the valve-rod extends through a packed joint or stuftlng-boxto the exterior, so as to be .connected to the device by which vit and the valve is to .be worked. The other end of the valve-rod passes through the chest and into a shield, d, into which the steam in the chest may freely pass through openings e, and thus the pressure of the steam will be always uniform on that end of the rod. Y
Upon columns or supports f f inside of the chest C is placed a jacket, g, which can be adjusted and then firmly held upon said supports by the set-nuts 2 2. The exhaust-passage may be made through this jacket and into the escape-pipe by means of the passage b extending through the side of the chest; ora similarlyclosed passage may connect with the exhaustport and the exhaust-steam carried or conducted away through it, said closed passage vmay enter the chest through the pipe h, and,
passing around the jacket g and to the port that is open, pass into the cylinder. The exhaust-steam passes out at b, and may go thence through the open valve O and into or through the passage b and ontat the side of the chest, or out of the top, if so preferred; or it may go from bnnderneatli the chest or through the cylinder, as above explained.
It is alleged for this construction and arrangement that the valve is always balanced, the pressure of the live-steam on its exterior and ofthe exhaust-steam on its interior being Vuniform or constant and equal at all times.
Having thus fully described our invention, what we claim therein as new, and desire to 4secure by Letters Patent, is-
1. In combination with the valve-rod, the shield d and steam-chamber t' therein, communicating with the steam in the chest, as and for the purpose described. j
2. In combination with the valve open at top and bottom, the jacket g and exhaust-passage b through it, as and for the purpose described and represented.
3. The combnatonof the chest, Valve, and inlet-ports with the exhaust-port b, when the latter is connected with the exhaust-passage b or with a. passage underneath the chest or through the cylinder, so as to use one or both exhaust-passages at the saine time, substantially as described.
