To @ZZ whom t may concern,.-

Beit known that I, CHARLES ANEsHAENsEL, J r., a citizen of theUnited States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Tater-Pumping Apparatus, of which the following is a specification.

My present invention is designed for use in that class of apparatus wherein a water-motor is devoted to use in pumping water for householdor such like purposes; and it especially l nominated the .cistern-water, which it usuallyis) is supplied tothe pumpqnotor through consists in a valve apparatus whereby that water which is pumped is enabled to shut off the supply of that water by which the motor is driven from said motor when a predetermined pressure is reached in the pipes containing the water which is pumped.

As is well known to those familiar with th subject, one great difficulty attending the use of water-motors in pumping water for domestic purposes has been that the motor is kept continuously under pressure from the water which drives it, and this occasions incessant wear uponl the valves of the motor, which rapidly destroys its efficiency. This trouble is aggravated by the fact that for a considerable portion of the time sucha motoi' is driven slowly back and forth by the small amount of water which passes through it when not in very active operation, at which times, as those familiar with the subject well know, such sand and grit as may be carried by the water remains in the valves more persistently and cuts said valves more seriously than when it is rapidly washed through, as when the motor is in full operation.

It will be understood, of course, that the water for driving the motor is that usually supplied under city pressure from the Waterworks, while that to be pumped is usually rain-water from a cistern. v

Referring to the accompanying drawings, which are made a part hereof, and on which similar reference characters indicate similar parts, Figure l is a side elevation illustrating in a diagrammatic manner a household water system embodying my present invention; Fig. 2, a central sectional view of the valve apparatus which constitutes the leading feature of said invention; and Fig. 3, a detail view similar to a portion of Fig. 2,

but with the valve seated or closed instead of open.

In operation the water which operates the motor (hereinafter denominated the city water, which it usually is) comes from the mains or source of supply through the pipe l to the motor 2, and the waste from said motor runs off into the sewer or other place of discharge through theexhaust or Waste pipe 3. My improved valve is interposed in the pipe l a suitable distance from the motor 2.

The water to be pumped (hereinafter dethe suction-pipe l and is delivered from said pump-motor to the plumbing-fixtures or tank, or both, through the pipe 5, which may or may not have branches, as b, running to various points, according t0 the plumbing system employed. I have shown the main pipe as running through a check-valve 6 to the tank 7, and said tank has a. delivery-pipe 8 and a waste or overiiow pipe 9, and to the latter in a modern plumbing system I prefer to connect the hot-water safety-pipe l0. All these matters, however, are matters of choice or preference and are arranged according to the taste of the user or the requirements of the situation to which they are to be adapted. From the pipe 5, however, runs a branch pipe 26 to a suitable chamber in the valve structure.- Briefly stated, the operation of this device is: When sufficient cistern-Water has been pumped to produce the predetermined pressure in the pipe 5 and in the branches or fixtures which it supplies, said pressure will overcome the spring 24 of this valve structure and shut off the city water which is passing through the pipe l. This will now be described more in detail. Referring now more especially to Fig. 2, the construction and operation of this controlling-valve will y ture and is operated in one direction by the spring 24, while it is operated in the other direction by the cisteru-water pressure coming through the branch 26 from the pipe 5 too against the cup 25, carried by the valve-stem. The pressure on the valve 22 is counteracted by a corresponding pressure o` the cup 27, said valve and said cup or any suitable opposing surface being of the same diameter, and thus constitutingabalancedvalve. The cup or piston 25, however, is of much larger diameter and is contained within a correspondingly-large chamber in the shell 28, which is mounted on the neck of the globevalve shell 20, as shown. The stuffing-box 29 on top of this chamber, through which the valve-stem 23 passes,is preferably cup-shaped at the upper end to receive a lubricant, as well as the lower end of the spring 24. The lower side of the chamber, below the cup 25, has a small vent o communicating with the outer air in order that there shall be no air compression within this chamber under said cup to impede its operation.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, in a water-pumping apparatus, with a water-motor pump, and pipes leading to and from the same, of an autom-atie stop-valve interposed in the pipe supplying the water for driving the motor, acasing extending upward surrounding the stem of said valve, a surface, as 27, above and opposing the top surface of said valve and balancing the same, a cup or piston on said valvestem in an enlarged portion of said casing, a

spring on an extended upper portion of said i stem arranged to normally hold said valve open, and a connection leading from above the piston or disk to pipe through which the water is forced from the pump, all substan tially as set forth.

2. The combination in a Water-pumping apparatus, with the water-motor pump and .i

the pipes leading thereto and therefrom, of an automatic single seat s'top valve interposed in the pipe supplying the water for driving the pump, a casing surrounding the stem of said valve and containing an enlarged chamber, a pistonin said chamber of a size :larger than the valveand` located above it, a pipe leading from said chamber above said fpiston to Vthe pipe through which the water `i`s forced by the pump, and a surface opposed toand balancing the valve mounted on the ,valve-stem and free from any seat, substan- "tially' as set forth.

3. The combination, in a waterpumping apparatus, with the motor-pump, and the pipes leading thereto and therefrom, of an automatic stop-valve interposed in the pipe supplying the water fordriving the motor',`

said valve being mountedin a casing extendL ing upwardly from the top of said pipe, and

having a stem which extends through said casing to outside the water-chamber, a spring surrounding the top of said stem arranged to act against the pressure of the water and normally hold said valve open, a disk opposed to and balancing said Valve mounted onsaid stem free from any seat, a piston or cup above said disk in an enlarged portion of said casinggan air-vent belovsT said piston, and a pipe connecting the chamber above said pis lton with the pipe through which the water is forced by the pump, substantially as set forth. y In witness whereof l have hereunto set my hand and seal, at Indianapolis, Indiana, this 28th day of February, A. D. 1900.
