STOP OR THROTTLE VALVE.
SPECFLCATIN forming part of Letters Patent No. 399,782, dated March 19, 1889.
Application iiled January 31, 1888. Serial No. 262,497. (No model.)
Z a/ZZ whom. it may concern.:
` Be it known that I, FRANK WV. RICHEY, of Armourdale, Vyandotte county, Kansas, a citizen of the United States, have invented a new and useful Improvement in Stop or Throttle Valves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.
My invention relates to that class of valves designed more particularly for use as steam throttle-valves for injectors upon locomotives; and it maybe said to consist in the novel construction, combination, and arra-ngement of devices, hereinafter set forth, and pointed out in the claims.
In the drawings, which illustrate the manner of carrying out my invention, Figure lis a side elevation of a valve embodying my invention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a detail view ofa cylinder or a cylindrical valve-seat used in making up the device. Fig. 4l is a perspective view of the valve-stem and its connected pistou-valve removed from the shell. Fig. 5 is a detail elevation of a threaded sleeve used in making up the invention, and Fig. (i is a detail view of a bushing.
The shell or casing A of my valve is composed of the usual enlarged cylindrical chamber and the two connections a l), which latter may be located as shown, as such is my preferred construction. A suitable housing, Il, is threaded into one side of the chamber A, and the stem D passes out through the upper end of said. housing. Located within said chamber is the open-ended cylinder F, which is provided with an annular series of ports or openings,f, near its lower end. Intermediate of its ends the outer diameter of this cylinder is reduced, as shown at F, so as to provide a passage-way for the liquid between said cylinder and the valvecasing, as shown more clearly in Fig. 2. Vithin this cylinder is arranged to both cover and uncover the openings j', accordingly as the valve is opened or closed, a piston-valve, E, provided with rings L- of ordinary construction.
The lower end, i, of stem D is located in socket j, formed in the upper end of this valve. It will thus be seen that the liquid entering the valve-Casin g through connection l) will always ten d to press the valve upwardly, so that no special arrangement need be made for pulling the valve open.
For pushing the valve downwardly and closing it, so that it will cover the inletopenings f, I locate a removable sleeve, C, on spindle D, and secure it there by means of alefthand thread, cl, and screw it down rmly against the flange or shoulder e, formed on said stem at a little distance from its lower end. This sleeve is threaded externally for engagement with an internal thread formed in bushing B, which latter is removably located in housing H. Said bushing is provided with a iiange or shoulder, lO, at itslower end, which prevents its being driven too far within said housing, said iiange coming in contact with the lower end, l2, of the housing when the parts are in proper position for operation.
The bushing B and sleeve C, which are the portions of a valve of this character subject to the greatest amount of wear when they become worn, may be replaced at small cost by unscrewing the housing H and removing the handle and the sleeve from said stem.
It will be observed that the left-hand thread d on stem D is engaged by a corresponding thread, e, located in the lower end of sleeve C, so that all danger of unscrewing the sleeve and thereby loosening it on said stem during operation is avoided. It is obvious that with this construction the stufiing-box I will be superiiuous, and the upper end of the housing H may as well be cut off square on line m00, Fig. 2, said stuffing-box being shown only to illustrate the fact that it can be used if so desired or required and rendered necessary. By constructing the upper end of housing I-I devoid of a stuffing-box, oil may be supplied to the threads within the casing at any time, which will obviate much friction and wear..
By the use of the piston-valve and cylinder F there will be no ground-joints to contend with, such joints generally causing much trouble bybecoming worn and cut and making it impossible to shut off at various times.
The upward pressure upon the valve E always tends to press it open, and when the stem is screwed outward to its limit the valve will. be wide open, and when saidsteinis screwed IOO downwardly till said piston covers the apertures f the valve will be closed, in which latter position it is shown in Fig. 2.
A valve thus constructed will remain steamtight during continual use for twelve months or longer without replacing any of its parts.
It will be observed that the bushing B, after once being inserted in housing-II, remains sta'- tionary, no wear occurring between it and said housing, and therefore said housing will not need replacement.
Having thus described my invention, what I claim is- 1. In a throttle-valve, the combination of a shell containing a removable cylinder provided with ports, a valve provided with packing-rings fitting within the bore of the cylinder, a stem in engagement with the valve and provided with external threads, a sleeve surrounding the stem and engaged by the threads, a bushing seated upon the upper extremity of the cylinder and the housing bored to receive and hold down the bushing, and hence the cylinder, substantially as described.
2. In athrottle-valve, a shell having a housing attached thereto, a bushing with a plain exterior located within the housing, a cylinder iittin g loosely within the shell and held in place on a shoulder in the shell by the longitudinal pressure of the bushing which is seated upon it, said cylinder being provided with ports, a valve provided with packing-rings, and a threaded stem in engagement with the valve, whereby it is operated, all arranged to operate in the manner and for the purpose set forth.
3. In a throttle-valve, the combination of a shell,a removable cylinder provided with ports and fitting loosely within the bore of the shell, a sliding valve and stem operating within the cylinder, a housing secured to the shell, aV
bushing iitting loosely within the bore of the housing and seated upon the upper extremity of the cylinder, whereby the latter and the bushing are held together in operative adjustment, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
