FLOAT-VALVE Specification of Letters Patent.
Patented May 25, 1920.
Application filed January 12, 1920. Serial No. 350,996.
' enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
My invention relates to float valves, and particularly to that type of float valve designed to regulate the flow of water into a tank through the bottom thereof, such water supply source being a water reservoir located at a higher level than the water level in the tank, thusproviding a constant water pressure in the inlet pipe leading to the tank. It is specially adapted for use in con junction with water supply systems for farmers, where open stock tanks are provided, and supplied with water from a wa ter reservoir located at a higher altitude. The water'supply pipe'in such cases is gen erally located underground and the entrance to the water, tank is through the bottom of the tank, and this entrance is closed by some fashion of a valve, quite frequently of the float variety.
The object of applicants device is to provide such a float valve of simple, inexpensive construction, adapted to be inserted in a pipe coupling, which may be carried at the end of the water supply pipe, and is in form as follows:
Figure 1 is an elevation of my device installed.
Fig. 2 is a vertical section.
Fig. 3 is an elevation of the device.
Fig. 4 is a top plan view of the valve seat.
In the drawings, let A. represent the water reservoir, 1). the water supply pipe leading from such reservoir to the open stock tank A 2, entering the same through the bottom thereof, and at the extremity of the water pipe is a pipe coupling 0. screwed thereon as shown in Fig. 2, internally screw threaded at each end.
A. valve seat 9. is provided, in tubular form, externally threaded so as to be received within the pipe coupling as shown, with flanged, perforated plate forming an end closure at the upper end, the perforations being indicated at y. A spherical valve 7t. adapted to receive a valve stem which stem f. 1s provided with a loop at the upper extremity so to be adapted for securing thereto means to which may be attached a float (Z. The connection between the float (Z. and the valve stem 7. isshown in Fig. 1. is a chain, or flexible connection 6. therebetween. This valve stem is shown as pass ing through a central, guide opening g 2 in the perforated plate forming the end closure of the valve seat 9. Encircling said valve stem and intervening the. valve it. and theend closure is a spiral spring This spring isadapted to force the valve open against the pressure of the water in the pipe 7). when the float is lowered by the fall of water in the tank A2 sufficientlv to permit such action of the spring. U
It is apparent therefore that a relation,
ship will exist between the spring and the pressure which Wlll be exerted on the spherical valve 7b. of such a character that the spring will be sufficient to overcome such water pressurev which of course would varv 1n different instances as the head of water, and thatthe float will be proportioned to close the valve against the action ofhthe spring. a
The action of the device is apparent from the above. The water will rise in the tank until the float closes the valve. As the water level in the tank is lowered, the spring will force the valve downward against the pressure of the water and the water will rise, passing around the valve and through the apertures j, inthe end closure,'lifting the float and closing the valve against the action of the spring. The water pressure cooperates with the action of the float in closing the valve and the size of the float is only sufficient therefore to overcome that difference in force existing between the expansion of the spring and the strength of water pressure.
The perforations through the end closure prevent any large particles from entering the pipe from the watering tank, and this feature insures efficient operation of the valve as these particles are prevented from than the diameter of the valve, an end clos- Y 2 I a V 1,346,999

In a water supply system, a water tank provided with an inlet pipe, a tubular valve seat adapted to be attached to said inlet pipe, an end closure consisting of a perforated plate at the upper extremity of said valve seat, a spherical faced valve of greater diameter than the interior diameter of said valve seat and provided with a valve stem extending upwardly through said end closure, a spiral spring encircling said valve stem adapted to hold said valve open, a float of suflicient proportion to close said valve against the resistance of said valve spring, means connecting said float with said valve stem.

3. In a float valve, a tubular valve seat adapted to be fitted within a waterpipe, an end closure consisting of a plate having strainer perforations therein for said valve seat, a spherical faced valve of greater diameter than the interior diameter of-said valve seat and oflesser diameter than the exterior diameter thereof, a valve stem} carried by c said valve projecting upwardly through said :end closure, a spiral spring interposed between said valve and said end closure so as to open said valve, a float of sufficlent proaortion to close said valve a ainst the resis- 1 l 2:,
tance of said spring, means connecting said float to said valve stem.
4, In a float valve, a tubular vali e seat adapted to be fitted within a Water pipe of lesser interior diameter than the diameter of said pipe provided with an end closure having a central guide opening therethrough and'having a seriesof strainer perforations surrounding the guide opening, a spherical valve adapted to be reversed on a valve stem and of lesser diameter than the exterior diameter of said valve seat but of greater diameter than the interior diameter thereof, a valve stem carried by said valve projecting' upwardly through the central guide opening of the end closure, a spiral spring encircling said guide stem intervening said valve and said end closure "and adapted to open said valve, a float of sufficient proportions to close said valve against resistance of said spring, means connecting said float with said valve stem.

In a float valve, a pipe coupling adapted to receive an externally threaded tubular valve seat, a perforated end closure consisting of a plate having a central guide opening therein at the upper extremity of said valve seat, a spherical valve of greater diameter than the interior diameter of said valve seat but of lesser diameter than the interior diameter of said pipe coupling and provided with a valve stem which projects upwardly through the guide opening in the perforated end closure of said valve seat, a spring inter-i posed between said end closure and said valve adapted to open sald valve, a float adapted to close said valve against the resist-.
