CHARLES H. EACH, or LACONIA, NEW HAMPSHIRE;

' p 1 Pour.

Application filed January 9,1920. Serial No. 350,256. 7 i T To all whom it may concern Be it'known that I, CHARLES H. BAOIL:

a citizen of the United States, residing at Laconia in the county ofBelknap and State of New Hampshire, have invented new and useful Improvements in Pumps, of which the following is a specification.

This invention relates to pumps and the I principal object of the invention is to provide means for furnishing a large supply of water such as for irrigation purposes and the like. V

' Another object of the invention is to make This invention also. consists in certain other features of constructlon and 1n the combination and arrangement of the several parts, to be hereinafter fully described. illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, ref- 'erence' will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in wh1ch:

the invention with parts shown in section.

Fig. 2 is a view taken at right angles from I Fig. 1.

Fig. 31s an elevation showing a pump;

. provided with a pair of cylinders and outlet pipes.

Fig. 4: is a horizontal section showing a 1 pump provided with four outlet pipes.

Referring to the Figs l' and 2, A indi-' catcs the frame which is formed of the discharge pipes land 2, the cylinder 3 and its suction chamber 4 and the cross pipes 5 and 5, the pipes being connected together by the couplings 6 and 6'. As will be seen the cylinder is located between the discharge pipes with its chamber 4: located above the planeof the lower ends of said discharge pipes. These lower ends are screw threaded and receivescrew threaded foot portions 7 which form rests for the frame. In this way the chamber 4 is supported abov the bottom of the well.

The suction chamber A has a valve seat 8 formed in its lower end and this end is closed by a screen 9. This screen is held in place by the ,bolts 10 and these bolts also connect the upper end of the chamber with the lower end of the cylinder 3. Openings are formed in the sides of this chamber and these openings receive the cross pipes 5. A

valve 11 is arranged in the chamber and the" valve rod 12 has its ends carriedbyspiders 13 at the upper andlower ends of the. chamher. A spring 14 on said-rodtendsto hold the valve upon its seat.

A piston 15 is located inthe cylinder 3 and the piston rod 16-passes through the coupllng 6 which is connected with the upper end of the cylinder. and through a sleeve 17 carried by the upper cross pipe 5. The upper nd of the piston rod is provided with openings 18 bywhich it may be'bolted to the reciprocating rod of a windmill or the like; though I prefer to operate the pump from a crank shaft, suitably driven, as will be described hereinafter.

Thepiston' rod passes through a packing gland'19 formed in'the' central coupling 6", connected to the top of the cylinder 3, and this gland is formed of a pair of plates 20,

suitably supported in the coupling and clamping between them a pair of rings 21 formed of leather or thelike; vThese rings have their inner edges folded over the inner j edges of theplates and encircle the piston Figure 11s an elevatlon of one form of. 1 r

rod.

The coupling 6 which connects each of the dischargepipes with its pipe 5 is provided with avalve seat 23 which is located above the point of junction of said pipe-5 A valve 24 slidably with the coupling. mounted on the stem 25 is normally held on this seat by the spring 26. The stem is carried by the spiders'27 at the-ends of the coupling. 1

.They are 'providedwith the smallholes 28 by which the water may leak from the pipes so asto prevent freezing in cold weather.

' A' platform 29 is supported bythe frame at one side thereof. and this platform carries the uprights 30inwhich the crank shaft 31 is journaled. This crank shaft is provided with thehand wheel 32 and the pulley 33 so that the shaft may be driven manually or by motive power. A pitman 34 connects the shaft with the piston rod and this pitman is connected with the shaft by the fiexibleconnection 35. It is connected with the piston rod by the flexible joint 36.

It will thus be seen that when thepiston is recip rocated in its cylinder by means of the rotation of-the crank shaft or by means,

.of a'windmill or the like, the upward stroke of the piston'will create a suction in the chamber and this suction will raise the valve and draw water from the well into the chamupon their seats. On thedownward stroke ber. This upward stroke ofthe piston will also hold the valves 24 of the discharge pipes the. valve 11' in the suction chamber will close and the water in said chamber will be forced by the piston through the pipes 5 .into the discharge pipes and the pressure will raise the valves 24 to permit the water to pass into the upper parts of said discharge pipes. On the neXt upward stroke of the piston these valves 24 will close to prevent the water inthe discharge pipes from flowing back into the suction chamber and a new charge of water will be sucked into said chamber from the well. I

In 'theform shown-in Fig. 3 I provide a pair of pumps, each pump being indicated by the character B and each pump is connected with a discharge pipe C. The piston rods of these pumps are connected with the crank shaft 31' which is provided with two cranks, as shown, said cranks being arranged to give one piston its down stroke while the 7 other piston is on its up stroke.

Each of the pumps and each of the discharge pipes is provided witha wide base part 7 for supporting the apparatus and the base parts of the pumps are connected with the lower ends of the suction chambers by the tubular members 7* which are provided with the slots 7 These parts are connected together by suitable bolts, as shown.

When this apparatus isplaced in the well or irrigation ditch the water will flow through the slots 7 into the tubular meman apparatus which is of simple construction and one which will provide a large flow of water for irrigation purposes and the like.

The entire apparatus may be placed in'the pondor ditch containing the water and the discharge pipes provided with connections for leading thewater a great distance from the apparatus.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes inthe construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

lVhat I claim is 1. An apparatus ofthe class-described comprising a frame formed of tubing and including a suction chamber having an inlet opening in its bottom, a spring pressed valve controlling said opening, a cylinder having its lower end in communication with the suction chamber, a piston in said cylinder, a piston rod connected with the piston and passing through the upper end of the cylinder,vertically arranged dis charge pipes arranged'parallel with the cylinder and suction chamber, transverse tubingcon'necting the discharge pipes with the cylinder and chamber, and the tubing connect-ed with the chamber being in communication with said chamber and said discharge pipes, spring controlled valves in said dis-' ing in its bottom, a spring valve controlling said opening, a supporting member connected. with the lower end of the suction chamber and having slots therein for permitting the passage of, water to the inlet opening, a vertically arranged discharge pipe,transverse tubing connecting said discharge pipe with the cylinder and chamber, the tubing connected with the chamber being in communication with such chamber and the discharge pipe, a spring controlled valve in said discharge pipe, a platform supported on the frame, uprights 011 the frame, a crank shaft carried by the uprights and a pitman connecting the said shaft with the piston rod.

In testimony whereof I aflix 1n si nature. CHARLES H BKc'H.
