To aZZ whom, it may concern: 7

Be it known that I, CHARLES B. J ONES, a citizen of the United States, residing at Roanoke, in the county of Roanoke and State of Virginia, have .invented certain new and useful Improvements in Pumps, of which the following is a specification.

My invention relates to an improved hydraulic pump; and the main object of my invention is the provision of a pump which is composed of a combination of standard pipefittings and check-valves so connected as to made in accordance with my invention. Fig.

2 is a top plan View thereof.

Referring by numeral to the drawings, the

numeral 1 designates the induction pipe, which is connected to the impetus-valve casing 2 by means ,of the Tcoupling 3 and the nipple I. This impetus-valve casing is placed in vertical line, as shown in the drawings, so that at each recoil of the column the impetusvalve will drop of its own weight and will be closed again when maximum momentum is again attained through the induction-pipe. The recoil of the column recoils after spending its force against the cushioned air in the air chamber 5 and the water just thrown through the check-valve 6, mounted in the T-coupling 7, which is connected to the T- coupling 3 through the medium of the nipple 8, the T-coupling 19, nipple 20, and the elbow 18. The air-chamber is in communication with the T-coupling 7 through the nipple 9,

T-couplihg 21, and the nipple 22. At the instantthe force of the column of water and the pressure of air in the air-chamber are equal the expanding tendency of the air takes advantage of the column of water and causes it to rebound, while the .cushioned air in the air-chamber continues to expand upon the water just thrown through the check-valve, lifting it to a point of discharge.

Mounted in the lower member of the T- coupling 21 is an elbow 23, to which is connected a reducing-bushing 13 for the connection of the small eduction-pipe 14, said eduction-pipe being substantially one-half the diameter of the induction-pipe. Idrill an opening 15 in the T-coupling 7 to avoid the forming of a vacuum at this point and also to admit air at each recoil of column. I have also found that air is forced through the check-valve by each succeeding stroke of the column and rises in the air-chamber to prevent back pressure.

I employ a valve-stem or tension-screw 16 to regulate the flow of water through the exhaust-opening 17,thus regulating the machine to use little or much water, as the circumstances may require, as it limits the movement of the impetus-valve 17 within the impetus-valve casing.

This construction of pump is adapted to be placed below a level with the spring, so as to secure a gravity flow of spring-water from the spring to the overflow-point of spring-pipe 30; but before reaching this point the spring-water flows through the nipple 29, thence passing through the check-valve 28 at each recoil of the drive water column, dropping on down through the elbow 26 and elbow 18 through the nipple 25, reducing bushing 24: and nipple 19, where at each stroke of the drive-column spring-water is driven through the checkvalve 6 beneath the air-pressure in air-chamber and is lifted to the point of discharge. Connected to the upper member of the nipple 29 is the overflow-pipe 33, said nipple 29 being connected with the casing 27 through the supply-pipe 32. The overflow-pipe 33 can also be used to return the overflow to the spring, as well as to obviate concussion in the springwater pipe at each closing of the check-valve 28 by the stroke of the drive-column. It will also be noted that all spring-water passing through the check-valve 28 is trapped and its only means of escape is through the checkvalve 8.

By having the spring-water lying in a trap formed by the valves and fittingsthat is, lying above the valve and under the air-chamber-the spring-water will fall at each receding of the column in place before the valve, thus without any liability of mixing with the water which is used as a motive power.

I claim an advantage in using this form of machine for the reason that all of the valves, with their different connections, are readily accessible when it is desired to remove the foreign substances and accumulations that lodge in the various parts of the machine, as all that is necessary to remove the foreign substances is to remove the top from the valvecasings and clean out the same. By reducing the lower end of the air-chamber I also get a greater pressure concentrated at the lower end thereof, so as to produce the desired result in pumping the clear water.

From the foregoing description it is evident that I provide a pump which is very simple, durable, and inexpensive, which dispenses with the employment of diaphragms, as is the general use, which can be easily repaired, as it is made from standard pipe-fittings and check-valves, thus dispensing with the extra costs of dies and molds to cast the different parts, and which is thoroughly efficient and practical in use.

The construction set forth in Fig. 2 is designed where the pumping fluid or motorpower is muddy or impure water which is adapted to be utilized to force a clear water from any suitable source through the supply 32.

hat I claim as new is 1. In a hydraulic pump, the combination of an induction-pipe, an impetus-valve casing above said induction-pipe and in communication therewith, an impetus-valve adjustably mounted within the said casing, a check-valve casing in communication with the inductionpipe but beyond the impetus-valve casing, a check-valve located therein, said valve-casing being provided with an opening with the outside air between the valve and the inductionpipe, an air-chamber having a reduced lower end in communication with the check-valve casing but above the same, an eduction-pipe in communication with the check-valve casing beyond the air-chamber, and a fresh-water supply connected intermediate and above the check-valve and induction-pipe.

2. In a hydraulic pump, the combination of an induction-pipe, a T- coupling connected therewith having one member in line with the induction-pipe and the other member above the same, an impetus-valve casing connected to the upper member of the T-coupling, an adjustable impetus-valve mounted in said casing, a check-valve casing provided with an opening with the outside air near the entrance thereof connected to the opposite end of the T-coupling, an air-chamber having a reduced lower end in communication with the checkvalve casing above the same, an eduction-pipe of lesser diameter than the induction-pipe in communication with the check-valve casing beyond the air-chamber, and fresl1-watei' supplying means connected intermediate and above the check-valve casing and the induction-pipe.
