VALVE.
SPECIFICATION forming partl of LettersPatent No. 588,430, dated August 17, 1897.
yApplication filed May 1, 1896. Serial N0. A589,842. (Nomoclel.)
To all whom it may concern,.-
Be it known that I, LOUIS J. HIRT, a citizen of the United States, and a resident of Brookline, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Valves, of Which the following is a specification.
Myimprovement relates to slide-valves having relief-ports or secondary valves for relieving the pressure on the valve in order to permit it to be operated with greater facility; and it consists of a novel construction'and arrangement of the valve and of the mechanism by which the relief part is operated.
In the accompanying drawings, illustrating my improvement, Figure 1 is an end elevation of the valve, and Fig. 2 is a side sectional elevation of the same. p Y
A A is the valve-body and is ,introduced into .or forms part of the steam-pipe.
B'is the valve, which, as shown in Fig. 2, is tapering, as seen from the side, and when raised or opened slides into a chamber C, mounted on the valve-body. From the top of the valve extends avalve-steml), by which the Valve is raised or lowered. This valvestem passes through a suitable stuffing-box E and is provided With a screw-thread F, which engages with the hand-Wheel G. As Will be understood from the drawings, When the Wheel G is turned the valve-stein, and With it the valve, is raised until the valve is drawn up into the chamber C and is thus opened. As the pressure in the steam-pipe on the side of the valve is very great, much force must be used. to move the valve in order to open it. To lessen this pressure and therefore permit the valve to be raised easily, I provide in the valve B a secondary slidevalve H, Which is operated independently of from the side, as in Fig. 2, is likewise tapering and When raised slides into a chamber I, provided in the upper part of the valve B. From the valve H'eitends a valve-stem K,
This valve H, When viewed' lup into the chamber I by the valve-stem K.
The secondary valve being small and offering but 4little area to the pressure in the pipe, 6o
slight force is required' to open it, andas soon as opened it relievesthe great pressure on the large valve B. After the valve has remained opened a suflicient length of time and the pressure in the pipe has been reduced so as to permit the ready opening of the largevalve B the latter is raised by the Wheel G through the valve-stem D. At the same timethe wheel M is lifted up and carries with it the valve-stem K and valve H. The secondary valve is` therefore raised, togetherwith the"large valve, by means of its oWn valve-stem and by the operation of the one Wheel G.
In my vconstruction the several parts are very compact and convenient of operation, as the valve-stem of the one valve is Within the stem of the other, thus making the construction very simple and easy of operation.
In a valve, the combination with the valve B, valve-stem D, and Wheel G, of the secondary valve H, valve-stem K, passing through the stem D, and Wheel M, substantially as described.
