CHECK VALVE.
(No Model.)
Patented Aug. 24,1897.-
lllllllllll llllIWll UNITED STATES PATENT OEEICE.
IIENRY REINACII, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO CHARLES REINACH, OF SAME PLACE,
CH ECK-VALVE.
SPECIFICATION forming part of Letters Patent No. 588,779, dated August 24, 1897.
Application-filed December 26, 1896. Serial No. 616,998. (No model.)
To all whom t may concern,.-
Be it known that I, HENRY REINACH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvementsin Check-Valves, of which the following is a specication.
The object of my invention is to provide a simple, economical, and efficient check-valve; and the invention consists in the features, combinations, and details of construction liereinafter described and claimed.
In the accompanying drawings, Figure lis an elevation of my improvement as attached in position ready for use 5 Fig. 2, a vertical longitudinal sectional elevation of my improved check-valve; and Fig. 3, a transverse sectional view, taken on line 3 of Fig. 2, looking in the direction of the arrow.
In the art to which this invention relates it is well known that if a chip or piece of dirt gets caught between the. valve and seat it keeps the valve open and allows the water or iiuid to seep through, thus destroying the efficiency of the valve. Again, in valves of this particular class if it be desired to let the water out that is above or to the rear of the check the pipes have to be taken apart and the valve removed, so that it causes considerable annoyance and delay to let the Water or fluid out. My invention is intended to remove these objections and provide a valve in which the danger of chips or dirt interfering with the proper working thereof is minimized and which is further provided with mechanism by which the uid above the check may be allowed to pass through without disturbing the valve proper.
In constructing my improvement I preferably make a valve-casing in two parts A and A. The part A isI provided with a tubular raised seat portion a, having a sharp upper portion a', on which the valve proper may rest. This seat portion is so constructed and arranged that it provides an annular chamber a2 between it and the casing.
I provide a valve proper, B, having depending wings b, that are inserted in the tubular portion of the valve-seat and act as a guide, while the upper portion of the valve is provided with a rod B', that is passed through a perforation in a guide-bar b. I provide this valve with a cushion portion b2, that impinges against the seat, so that when fluidpressure is exerted against the valve the seat is forced slightly into the cushion portion and effectuall y prevents the passage of liquid or fluid therethrough. From the foregoing it will be seen that if any chips or dirt pass up through the tubular part A2 of the valvecasing it will be washed over the sharp edge and not retained on the seat portion to interfere with the proper working of the valve.
In order to allow the liquid or fluid that is confined above or to the rear of the valve proper to escape, I provide the tubular portion a with a perforation or supplementary valve-seat C and screw-thread a valve C in the valve-casing, so that by turning this screw in or out the perforation or valve-seat is opened or closed and permits the liquid to escape without necessitating the disconnecting of the pipes or taking down the valve.
While I have described my invention with more or less minuteness as regards details and as being embodied in certain precise forms, I do not desire to be limited thereto unduly any more than is pointed out in the claim. On the contrary, I contemplate all proper changes in form, construction, and arrangement, the omission of immaterial elements, and the substitution` of equivalents as circumstances may suggest or necessity render expedient.
I claim- In a check-valve, the combination of two tubular portions forming the valve-casing and secured together so as to be separated longitudinally, the lower portion being provided With a centrally-raised tubular portion forming a valve-seatA and an annular channel between it and the exterior casing, a cushion-valve having depending arms longitudinally movably seated on the valve-seat and provided with an upwardly-projecting rod, a guide-bar in the upper valve-casing to assist in positioning the valve and guide it in its movements, an auxiliary-valve perforation in the upwardly-projecting valve-seat located above the bottom of the annular chamber, and a screw threaded valve extending through the valve-casing to open or close this auxiliary-valve perforation, substantially as described.
