IMPROVEMENT IN CHECK-VALVES FOR STAND-PIPES.
Specification forming part of Letters Patent No. 1131,9133, dated September 10, 1872.
SPEoIEroATIoN.
To all whom it may concern:
Be it known that I, GEORGE W. HALLEN- BECK, Jr., of the city of New York, in the county of New York and State of New York, have invented certain Improvements in Check- Valves, of which the following is a specificatio n, reference being hadto the accompanying drawing.
My invention consists in certain improvements in check-valves.
Figure 1 is. a vertical section of my improved valve; and Fig. 2 is a section view, showing the eccentric and the lower part of the stem detached.
The object of my invention is to make a valve by which the water may be readily discharged from' the pipe of a pump or similar apparatus. In the winter it is often necessary to discharge the water from the pipe to prevent its freezing and thereby stopping the ilow of water or bursting the pipe. With the ordinary valve the water could not be discharged without unscrewing the valve, and when, as is commonly the case, the valve is placed in the first or second story of the building, the water which comes from the pipe is discharged on the floor, besides taking up considerable time and making a great deal of trouble. Besides, by repeatedly unscrewing the joint the screw-threads become worn and this causes a leak. It is also necessary to let the water out when the pipes are to be repaired, and here, again, the joint of the valve would have to be unscrewed. The pipes are generally painted or boxed up and fastened back against the wall. With the old valve it was necessary to tear the pipe away from the wall to make any repairs. With my valve I do away with all these objections.
In constructing my improved valve I pro vide a shell or case, A, provided with a valve, B, and guide I), as before. Below the guide b I place a shaft, 1), mounted at one end in a suitable bearing, 0, which-is screwed in from the opposite side, and at the other end passing through a stuffing-box, F. This shaft is provided with an eccentric, O, as shown in Fig. 1, and in detail in Fig. 2, said eccentric being fastened rigidly on the shaft, and provided at the end which extends outside of the case with a suitable handle, 6. The valve B is provided with a stem, asusual, which stem extends down or nearly down tothe eccentric 0 when said eccentric is turned down. When the handle E is turned in the proper direction the valve-stem a is raised by means of the eccentric 0, thereby allowing the water which is above the valve to escape down through the pipe into the cistern, well, or other place from which it is drawn.
The advantages of this improvement are obvious. By it the water can at any time be let out of the pipe and thus prevent freezing and when necessary to repair the pipes the water can be let out without flooding the apartments. It is extremely simple and cheap.
I am aware that eccentrics have been used in faucet-s for operating a valve, and, therefore, I do not claim such; but-- What I do claim is The arrangement, in a stand-pipe, of the valve B and eccentric G, as and for the purpose herein set forth.
