` raise water from a well and discharge the saine into a trough for delivering 'at a distance, and has for its prime object to provide a novel and improved multiple-'cylinder pump of the hollow piston-rod type, with y novel and improved means for supporting the cylinders, and for effecting the discharge or flow of water from the pump.

Other objects of the invention relating more particularly to details of construction will be made clear in the description following and illustrated in the accompanying drawings, in which- Figure 1 is an elevation of the complete pumping apparatus made in accordance with this invention in position in a well;

Fig. 2 is a. vertical section of one of the pump cylinders taken on the line 2 2;

Fig. 3 is a detail cross section of the pump cylinder and piston on the line 3-3 of Fig. 2, and

Fig. 4 is a cross section of the pump cylinder on the line 1 -1 of the same figure.

In the drawings, 10, indicate the pumps complete, two only being shown in the equipment. This number is not material and may be changed as circumstances require. Each pump 1'() comprises a long cylindrical body extending from the top of the well A downward into the water andpis formed of a number of sections 11 with il anges 12 on their ends and bolts connecting the flanges. Bolted to and forming a continuation of the lowermost section 11 is the pump cylinder 13 within which a piston 111 reciprocates. The cylinder 13 opens at its lower end into an inlet valve chamber 15, on the bottom o1 which is formed a seat 16 for an upwardly opening valve 17, provided with a downwardly projecting stem 18 guided by a spider frame 19 formed on the bottom of the valve chamber and exterior thereto. The spider frame serves as a support for a screen or strainer 20 when such is necessary.

The pumps 10 are supported within the well A by a framework 21 which may be made of metal or wood, here shown as of metal, comprising a superstructure upheld by a plurality of I-beains 22 extending across the top of the well and anchored in the sides thereof. Channel bars 23 extend between the Isbeams and serve to strengthen and stiifen the framework. Certain of the I-beams 22 have eyes 2li on their under sides and connected to these eyes are rods 25 that extend downwardly into the well and there bolted to tie-rings 26 secured around the tops of the pump cylinders 13l. Turnbuckles 27 on the rods 25, when tightened, draw the pumps 10 upward so that the top flanges 12 of the uppermost sections 11 are pressed lirmly against the l-beams to hold the pumps against movement and rigid ywith the framework 21. The tieerings 26 hold the lower Vends 'of the pumps a proper distance apart, and to prevent lateral movement of said pumps, brace rods 23 exten/d from the tie-rings 26 to the walls of the well A.

The piston 14C has a central valve chamber 29 opening downwardly, within which is a ball valve 30, held centrally therein and away from the walls of the valve chamber by vertical ribs 31. Slidable laterally in dovetailed grooves in the bottom of the piston 14,

beneath the valve chamber 29, is a plate 32 having an opening therethrough, the sides of which form a seat for the ball valve 30. A threaded opening 33 passes upward through the piston from the valvepchamber 29 and screwed therein is a nipple 34: locked against rotation by a lock nut 35. A flanged collar 36 on the upper end of the nipple aiiords means for attaching a hollow piston rod 37 having a like collar 36 on its lower end.

The hollow piston rod 37 is formed of a number of pipe sections connected by flanged collars 38 similar to collars 36 and extends upwardly through the framework 21 where it is guided in its vertical movement by packing glands 39 and l10. Surrounding the piston rod 37 within the pump are a series of float chambers l1 that tend to elevate the piston and piston rod when the pump is operating and serve to counteract the dead weight of these parts and thus reduce the power necessary to drive the apparatus.

Through' the piston 14: exterior to the valve chamber 29 are formed a plurality of arc shaped openings 42 for the passage of water upwardly therethrough. These openings are guarded by a downwardly closing annular valve 43 that seats by gravity on the top of the piston and is guided in its vertical movement by headed studs 44 that pass freely through holes in the valve and screw into the piston. When the piston is depressed the valve 43 and also the ball valve 30 are raised and permit water to enter the cylinder 13 and also the hollow piston rod. A reverse movement of the piston closes the valves and the water above them is raised. From one side of each pump l0, near the top of the well, projects a branch pipe 45 that opens upwardly to permit the escape of water into a valve chamber 46 secured on the top thereof and containing a downwardly closing valve 47. Bolted to each valve chamber 46 is one leg of a Y-branch pipe 48, the connected ends of which deliver into a discharge pipe 49 that'rises vertically a suitable distance and then turns into a substantially horizontal position as shown, the mouth 50 being open.

Rising vertically from each gland 40 on the top of the framework 21 is a short section of pipe 5l forming a receivingchamber greater in diameter than the hollow piston rod 37, within which the upper open end of said rod travels as the pump is operated and into which water from said rod is delivered. A valve boX 52 is attached to the upper end of the pipe 51 and contains an upwardly opening ball valve 53. F rom each valve box 52, one leg of a Y-branch pipe leads and is connected to a discharge pipe 54 that 'rises vertically and then extends horizontally above the larger discharge pipe 49, its end 55 turning downwardly and entering the pipe 49 near its mouth 50. A clamp 56 holds the two discharge pipes firmly together.

The pump pistons 14 are operated by a crank shaft 7l ournaled on the framework 2l, through connecting rods 72 pivoted to cranks 73 on said shaft and to the hollow piston rods 37.

The operation of the apparatus is self evident from the above description and needs no further explanation. The pumps 10, whatever the number used, are all alike, and the description of theone cylinder hereinabove given is applicable to all.

I claim Y l. In a pumping apparatus7 the combination with aplurality of pumps, and a framework for supporting the same in a well, of means at the lower ends of the pumps for rigidly fastening them together, rods connected to said fastening means and to said framework, and adjusting means on said rods for holding the upper ends of the pumps immovably against the framework.

2. In a pumping apparatus, the combination with a plurality of pumps, a framework Vfor supporting the same in a well, of tierings surrounding the lower ends of said pumps and rigidly fastening them together, rods connected to said tie-rings and to said framework, turn-buckles on said rods for drawing their lower ends upward and holding the upper ends of the pumps immovably against the framework, and tie-rods extending from the tie-rings to the sides of the well.

3. In a pumping apparatus, the combination of a plurality of pump cylinders, a piston in each cylinder, a group of ports through each piston, a downwardly closing valve guarding each group of ports, a discharge pipe connected to all the pumps, a downwardly closing valve between each pump and the discharge pipe, a hollow piston rod connected to each piston and opening into a valve chamber therein, an upwardly opening valve in each valve chamber, a receiving chamber surrounding the upper open end of each hollow piston rod, a discharge pipe connected to all'y of said chambers and delivering into the first named discharge pipe, and a downwardly closing valve between each chamber and the discharge pipe. Y

In testimony whereof I aiiix my signature.

EDWARD BENSON.
