UNITED. STATES I 1,716,377 PArE'r OFFICE,
ROBERT GRANT, OF HOLLYWOOD, CALIFORNIA, ASSIGNOR OF ONE FIFTY-EIGHTH'TO DOROTHY IOLA GRANT, OF LOS ANGELES, CALIFORNIA.
VALVE Application filed January 12, 1928. Serial No. 246,315.
This invention relates to fluid pressure valves and its general object is to provide a valve that is retained in open position by normal pressure, but will automatically close when the pressure is shut off or gets below a non-usable degree.
A further object of the invention is to provide a fluid pressure valve primarlly! designed to control gas lines and that will close when the pressure in the line is below normal or ceases, and must be manually opened, with the result the escape of gas will be prevented.
Another object of the invention is to provide a fluid pressure valve of the character set forth, that is simple in construction, inexpensive to manufacture and efiicient in operation and service.
This invention also consists in certam other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims. In describing my invention in detail, reference will be had to the accom anying drawings wherein like characters enote like or corresponding parts throughout the several views, and in which:
Figure l is a vertical sectional view taken through the valve which forms the subject matter of the present invention and showing parts thereof in elevation.
Figure 2 is a front view thereof.
Figure 3 is a detail view of the spring washer.
Referring to the drawings in detail, the reference numeral 1 indicates a casing which may be cylindrical-in formation and includes closure plates 2 and 3. Extending through one wall of the casing is a pipe section 4, threaded at its outer end to accommodate a pipe arranged in communication with a suitable source of gas or other fluid, and this pipe section 4 provides the inlet for the casing as will be apparent.
Extending into the casing is an outlet pipe section 5. The outer end of the outlet pipe section is threaded and the inner end is provided with a beveled inner edge to provide a w seat 6. Frictionally received by the portion of the outlet pipe section within the casing is a sleeve 7 provided with openings 8 disposed upon diametrically opposite sides thereof, and this sleeve 7 acts as a guide and accommodates a valve member 9 having a con1eal lower end 10 adapted to be received by the seat 6 as shown by the dotted line position of the valve member in Fi ure 1. The valve member has rising there rom i-c1 ntrally of its free end an apertured ear The closure 3 is formed with a centrally disposed opening 12 and is recessed on its inner side about the openin as at 13 toreceive a spring washer 14 0 star formation as best shown in Figure 3, and this spring washer is dished for the purpose of engagmg a diaphragm plate 15 secured in confrontlng relation with respect to the closure plate 3. Extending through the opening 12 and having secured thereto the spring washer 14 and diaphragm plate 15 respectively through the instrumentality of nuts 16, is a rod 17. This rod is formed with an annular recess adjacent one end to accommodate a ring 18 which passes through the aperture of the car 11.
Secured to the outer face of the closure plate 3 is a substantially U-shaped bracket 19 having formed in the bight portion a notch 20 which is adapted to receive the outer end of the rod 17 as shown in full lines in Figure 1, and this outer end of the rod 17 is retained in the notch 20 by pressure of fluid passing through the casing as it will be apparent that the pressure of the fluid will cause the diaphragm plate 15 and spring washer 14 to exert pressure against the rod in an outward direction, but in the event the pressure should decrease to an extent to allow the diaphragm plate and washer to assume their normal position, it will be obvious that they will carry the rod to the dotted line position as shown in Figure 1 and allow the valve member 9 to close.
From the above description and disclosure of the drawings, it will be obvious that I have provided a valve that is primarily designed for gas lines where the pressure fluctuates and in the event the pressure in the line should decrease to a non-usable degree, the valve will close and must be manu ally opened.
It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.
I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.
What I claim is: 1. A valve of the character described comrising a substantially cylindrical casing having inlet and outlet openings therein, closure plates for the ends of sald casing,one of said plates having an opening therethrough, a valve member'for controlling the outlet opening, means to guide the valve member, a rod carrying said valve member, said rod passing through the opening formed in one of the closure plates, means u on the outside of the casing for detacha le engagement with the outer end of the rod to retain the valve member in open position, and flexible means controlled by the ressureof fluid passing through the casing 'or controlling the position of the rod.
2. In a pressure operated valve, a casing havin openings therein one of said openings efining an inlet openings and another of said openings defining an outlet opening, a rod extending through one of the openings of the casing, a i pressure controlled diaphragm supporting the rod, a valve supported by the inner end of the rod to control the outlet 0 ening and a notched bracket upon the outsi e of the casing for engagement by the rod to hold the valve in open position when the diaphragm is under pressure.
In testimony whereof I aflix my signature.
ROBERT GRANT.
