ELMER H. BRIDENBAUGH, OF DAYTON, OHIO.

AUTOMATIC PUMP-REGULATOR.

reagire.

To all whom it may concern:

Be it known that I, ELMER H. BmDnN- BAUGH, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements 1n Automatic Pump-Regulators; and I do de- Clare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying dra-wings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in automatic pump regulators. y

The object of the invention is to provide a device of the above type that is simple and durable in construction and efficient in operation.

Other objects are attainable, as will appear from the specification and which are particularly pointed out in the claims.

Referring to the accompanying drawings, Figure 1 is a side elevation of the invention as applied to a pump of the wind-mill type having my improvements; Fig. 2 is a vertical longitudinal sectional elevation of the regulator; Fig. 3 is a section on the line a a of Fig. 2; and Fig. l is a section on the line o o of Fig. 2.

Throughout the specification and drawings, similar reference characters indicate corresponding parts. l

'Referring more particularly to the drawings, 1 represents a pump cylinder provided with a discharge pipe 2, which, in the case illustrated in the drawings, leads to an underground reservoir 3 into which the water is pumped against air compressed therein. The cylinder 1 is provided with a piston rod 4 attached to a pump rod 5, which is, in turn, connected to the actuating mechanism of a windmill when the motive power is of that kind. In the present case the windmill (not shown) is mounted on a frame 6, and the pump may be provided with a lever handle 7 and a discharge spout 8, which may be used independently of the windmill. To enable the wind-mill to be placed out of operation when the desired quantity of water has been pumped, it may be provided with a pull-out cord 9 which is connected to the vane of the mill and which,

when pulled downwardly, will throw the vane to one side, thereby placing the sails out of the path of the wind which prevents its continued operation. As the wind-mill parts are well known and understood, it has not been deemed necessary to illustrate them. To enable the cord 9 to be pulled automatically when sufiicient water has been pumped, and which is indicated by the. pressure thereof, the following device is provided.

Attached to the lower end of the pull-out cord 9 is a piston rod 10, which passess through a stufhng boX 11. The said rod 10 is provided with a. piston 12 on its lower end. The piston 12 reciprocates in a cylinder' 13 provided with a bracket 14 which may be attached to the discharge pipe 8, and through which the cylinder is supported. The chamber within the cylinder 13 above the piston connects with the reservoir 3 through the pipe 2, a lateral communicating pipe 15, and a passageway 16. Both the lateral 15 and the passageway 16 communicate with a chamber 17 in a housing 18; and within sai-d chamber 17 is a valve 19 parts of which coperate with seats 20 and 21 and control the passage of water from the discharge pipe 2 to the cylinder 13. The said valve is -ioined to a guide cylinder 22 mounted within the housing 18, both parts being normally held down by a spring 23 mounted on a yielding stem 24. The tension of said spring may be regulated by a nut 25. The stem 24 at its lower end engages the upper side of said valve and its upper end enters an aperture in the nut 25. lll/Then the pressure of the water in the delivery pipe 2 and the lateral 15 becomes sufficient to overcome the tension of the spring 23, the valve portion 19 instantly opens and allows the water to enter the passageway 16 and cylinder 13, thereby lowering the piston 12 and cord 9 and thus placing the windmill out of an operative position. The valve 19 does not completely open until the piston portion thereof passes the seat 21, which prevents the said valve chattering when said valve opens.

The housing 18 is provided with a seat 26 adapted to be engaged by a valve 27 on the guide cylinder 22 when the valve 19 is opened. When the valve 27 is in engagement with the seat 26, it prevents the water escaping around the guide cylinder, thereby insuring the entire pressure of the water in the chamber 17 being exerted against the piston 12. When the pressure of the water in the discharge pipe 2 falls sufficiently to allow the spring to close the valve 19, which pressure is controlled by the nut 25, the water in the cylinder 13 above the piston escapes through a port 28. The port 28 is controlled by a valve 29 in a head 30 mounted above the housing 18. The valve 29 is connected to the stem 24 by a stem 31; and

-the position of the valve 29 is such that,

when said valve 19 is closed, the valve 29 will be opened, and vice versa. As a consequence, after the valve 19 is opened by the water pressure, the valve 29 will be closed, which prevents the water escaping through the port 28 when the piston is being moved downwardly and is being held in a lower position by the water. When the pressure of the water in the discharge pipe 2 falls to a point that allows the valve 19 to close and the valve 29 to open, the piston 12 will be relieved from the pressure of the water and can consequently be elevated. This elevation may be accomplished by any means, such as the vane of the mill itself, which will be thrown into the wind when the pullout cord 9 is released as is common with windmills.

The chamber 17 may be provided with a safety valve 32 mounted in al housing 33 provided with an outlet 34. The valve 32 is controlled by a spring 35, the tension of which may be adjusted by a nut 36. The safety valve 32 prevents the water exerting an excessive pressure in the chamber 17 and cylinder 13.

It may be stated that when the tank 3 is nearly full, and the pressure has dropped slightly below that at which the regulator is set, the valve 21 may be closed and the valve 29 opened by pressing on the stem 31, thereby allowing the piston 12 to ascend and the windmill to be placed in operation. The water may therefore be discharged from the pump without passing through the reservoir, which allows a supply to be maintained. It may be further stated that the area of the valve 19 controls, in connection with the spring 23, the point at which the valve will open, and that the area of the valve 27 controls, in connection with the spring 23, the point at which the valve 19 will close. The differential area of the valves 19 and 27 therefore regulates the difference in pressure between the opening and closing of the valve 19.

Having described my invent-ion, I claim:

1. In a device of the type specified, a pump, a reservoir, a discharge pipe leading from the reservoir to the pump, a cylinder having an outlet therein, a piston within said cylinder, a housing having a chamber therein, said chamber communicating with said cylinder and said reservoir, a valve mounted in said chamber and controlling the passageway between the reservoir and the cylinder, a guide cylinder mounted in said housing and forming a guide for said valve, a second valve mounted in said guide cylinder and adapted to seal the joint between the housing and guide cylinder when said first named valve is opened, and a third valve controlling the outlet of the cylinder and actuated by said first named valve.

2. In a pump regulator, the combination with a pump cylinder, a reservoir, and a discharge pipe forming a communication between said pump cylinder and said reservoir, a cylinder 13 having an outlet, and a piston in said cylinder, of a housing 18 forming a chamber which communicates with said cylinder and said reservoir, a valve 19 mounted in said chamber and controlling the communication between the reservoir and said cylinder 13, the valve 19 having an extended portion 22 forming a guide therefor, a spring-controlled stem 24 normally controlling said valve and extension, a valve 29-30 mounted above said housing 18, the stem of which is joined to the stem 24., said valve 29-30 being ada-pted to control the outlet to the cylinder 13, and a valve 26-27 moving in unison with the valve 19 and adapted to seal the joint around the valve extension 22, substantially as herein shown and described.

In testimony whereof I affix my signature, in presence of two witnesses.
