. WATER RELIEF VALVE.
APPLICATION FILED APB. B.1907.
W INVENTOR By K i ATTORNEY GEORGE W. DAY, or GASPORT, NEW YORK.-
WATER-RELIEF VALVE.
Specification of Letters Patent.
Patented March 10, 1908.
Appliationiiled, April 8, 1907. Serial No. 366,976.
To all whom it may concern:
Be it known that I, GEORGE W. DAY, a
, citizen of the United States, residing at Gasort, in the county of Niagara and State of liTew York, have invented certain new and useful Improvements in Water-Relief Valves,
of which the following is a specification, reference being had to the accompanying draw- Ily invention relates to'improvements in water-relief valves; and an object of .my invention is to provide a valve of this character which will be simple in construction and eflicient in operation, and which will kee the pressure of the system it controls uniform Within narrow limits.
In the drawings illustrating the principle of my invention and the best mode now known to mezof applying that principle, Figure 1 is a central vertical section; and Fig. 2 is a plan view. The'casing is twoart, the, upper part a being screwed into t he lower part b. The
- latter is provided with the inlet pipe -connection 0 and the outlet pipe' connection-d, both of which are threaded. Extending axially through the valve cas' is the stem or plunger e the lower end fwhich carries the disk valve f which is normally seated upon the valve-seat 9 made of any suitable material and firmly secured in the recess it above the outlet. Above the disk orcollar 11 formed about midway of the stem is placed a cup Washer or crimlp 7' held downupon the flange i by the nut between which and the cup Washer is interposed an annular washer m. Upon the latter bears one end of a coil spring 12. the other end. of which presses against the top of the upper art a ofthe valve-casing. The tension of t coil spring and the valve f leaves its seat, thereby per-' mitti water to flow from the inlet to the outlet in order to relieve the pressure. The
rush of the water ast the edge of the flange,
or collar 0 forces t e valve upon its seat before the pressure of' the system has been decreased elow the pressure for which the valve is set; and the pressure in the's stem is thereby kept within narrow limits, w 'ch is the function of this type of valve.- To the .upper end of the valve-stem is pivotally secured an arm 1) formed with a cam face which, when the arm is raised t'o'the dotted line position of Fig. 1 bears against the top of the part a. By these means the valvestem is raised to relieve the pressure to any desired extent.
I claim:
' 1. A water-relief valve consisting of a cas-. ing; a valve-stem mounted therein; a valve upon said valve-stem; a spring controlling said valve-stem; means actuated by the pressure of the water for opening said valve; and means upon said valve-stem and actuated by the water for closing thevalve; the last named means bein separate from said valve and on the side t' the opening controlled thereby. t 2. A water-relief valve consistin of a valve casing a valve-stem mounted t erein;
a valve upon said valve-stem; means for holdin said valveclosed against the pressure o the water; means actuated by the pressure of the water for opening said valve; and means for closing the valve after it has been opened by the ressure of the'water;'said last named means ein separate from the first named means and om said valve and on the side thereof opposite from the openvalve upon said valve-seat; meansactuated by the pressure of the water for raising saldx valve from said valve-seat against the action of the first named means; and a flange u on said valve-stembetween said valve and t e inlet to said casing; said flange being I GEO. W. DAY.
