VALVE.
SPECIFICATION forming; part of Letters Patent No. 788,986, dated May 2, 1905.
Application filed September 20, 1904. Serial llo. 225,208.
To all whom it may concern:
Be it known that I, HUBERT Z1Ns, a citizen of the United States, residing at Nicollet, in the county of Nicollet and State of Minnesota,
' have invented a new and useful Improvement in Valves, of which the following is a specification.
' My invention relates to an improvement in a valve and easing therefor to be used in connection with the discharge-pipe of a watertank which is used with a windmill or engine puililiping system for drawing water from a we The object of my invention is to provide means whereby when the drain-pipe running from the pump barrel to the water -tank freezes the water which may be drawn from the well by the pump or engine after such freezing will by its pressure cause the valve constituting part of my improvement to open and allow such water to escape into the pit or other suitable place, and thereby relieve the pressure which would damage the pump, rod, engine, windmill, or other parts of the pumping system.
My invention consists, therefore, in interposing an automatic valve below the freezingline between the water-tank and the pumping" system.
It consists, further, in certain novel features of construction, arrangement, and combination of parts, as will be hereinafter described, and pointed out in the claims, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of a pump and tank, showing the pitin vertical section. Fig. 2 is a vertical section of the valve-casing and valve. Fig. 3 is a perspective view of the valve removed from the casing. Fig. 4 is a similar view of the valve-seat.
A represents the pumping system, which in the present instance is a windmillpump that is, a pump which is operated by windmill power. B is the pit in which the pump is located, and C is the tubular well. D represents the tank usual with such systems, said tank being located above the level of the ground.
d is the discharge-pipe, which runs from the pump-barrel through the pit and connects with the tank D.
E represents the casing, which contains my automatic valve. Said casing consists of a short length of pipe threaded internally and externally at both its upper and lower end, as shown in Fig. 2. The internal threads at the upper end are to receive the nipple c, forming a valveseat, which is screwed into the casing from the top, the upper edges of said nipple having the cross-notches e, by means of which a flat bar may be used as a wrench to screw the same in as far as desired. The lower face of the nipple is made to form a valve-seat, against which the automatic valve F is forced. Said valve consists of the valve-face f and the fluted extension f, extending upwardly beyond the same, and the downwardly-pro ecting stem f, the lower end of which is made square.
G is a coiled spring bearing upwardly against the valve below the face and surrounding its stem. The lower end of spring G rests on the upper face of an externallythreaded thimble 6 the lower edge being provided with cross-notches e, by means of which it may be screwed into the valve-casing to regulate the tension of spring G, according to the pressure to which the valve is to be subjected.
The upper end of the casing is connected by a T-coupling to and suspended from the main discharge-pipe d within the pit B, where no frost can get to it.
A suitable valve will be placed in the spout of the pump, so that the water from the well may be discharged into the tank or from the spout of the pump, as desired.
The operation of the device is as follows: When the discharge-pipe freezes, as is frequently the case, the water which is forced from the well will by pressure on top of the valve (which has been adjusted before cold weather sets in) cause such valve to open and allow the escape of the water or a portion thereof into the pit, and thus prevent pressure from damaging the pump or its parts or the parts of the system which may be used-such as an engine, for instance. A pipe running from the valve to the top of the pit may also be used,
if so desired.
- The lower end of the valve is made square for turning the valve to inspect it to see if it is in order before cold Weather sets in. The object in having the valve hang downwardly is that it will always run dry and keep dry in summer-time.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- K h 1. In a pumping system, consisting of a pump and tank adapted to be filled therefrom, connections between said pump-barrel and the tank and an automatic escape-valve interposed in said connections between said pump-barrel and tank and adapted to be opened by pressure of water from the well when the pipe is stopped between the valve and the tank.
2. In a pumping system comprising a pump located in a pit, and a tank connected with the pump-barrel, an automatic downwardly-opening valve located in the pit between the tank and pump-barrel, adapted to be opened by pressure of water from the pump-well when the connection between the pump-barrel and the tank is frozen.
3. In a pumping system comprising a pump suitably operated and a tank having a discharge connection with the barrel of the pump, a valve mounted within a casing, a spring normally forcing said valve upwardly to its seat, and a nipple supporting the lower end of the spring, said nipple being adjustable within said casing tb regulate the tension of the spring, said valve and casing being located within the pit of the pump, and opening into the same, whereby when the connection between the tank and the pump-barrel becomes frozen, the pressure of water drawn from the well will cause the valve to open and permit escape of the water into the pit and prevent damage to the working parts of the pumping system.
4. In a pumping systemcomprising a pump and a tank having a discharge connection eX- tending to the pump-barrel, an automatic valve mechanism interposed intermediate the tank and pump-barrel in the discharge-pipe, said valve mechanism consisting of a casing internally and externally threaded at its upper and lower ends, nipples threaded into the upper and lower ends of said casing, the upper nipple forming a valve-seat, a valve within said casing forced against said seat by a spring surrounding its stem, said spring hearing at its lower end on the thimble threaded in the lower end of the casing, said lower thimble being adjustable whereby the tension of the spring may be regulated.
