SAMUEL K. EPLER, OF SAN DIEGO, CALIFORNIA.

PUMP.

Application filed June 7, 1913.

To all whom it may concern:

Be it known that I, SAMUEL K. EPLER, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented certain new and useful Improvements in Pumps, of which the following is a specification.

My invention relates to pumps.

Among the objects of the invention are: first the provision of an effective form of manually operated pump which will produce a continuous, even, and steady flow of the fluid pumped from a considerable depth; second to provide in a pump of this kind a plurality of fluid lifting elements and cooperating parts which will serve to provide a continuous suction so that a continuous flow of the fluid may be had; third, the provision in a pump of this kind of a plurality of fluid lifting elements adapted to alternately produce a suction and remain inactive for this purpose, one of said elements producing a suction while the other remains inactive for this purpose; and fourth, the provision in a pump of this kind when said lifting elements are in the nature of heads of a valve device such as hereinafter set forth, which enables the heads to function as above stated.

The invention resides in the novel arrangement and combination of the several elements or parts described hereinafter in connection with the accompanying drawings illustrating the preferred embodiment.

In said drawings: Figure 1 is a side elevation; Fig. 2 is a vertical sectional view; Fig. 8 is a vertical sectional view of the suction tube; and Fig. 4 is a detail perspective view of the suction operating valve employed.

Throughout the views of the drawings, like reference characters designate like or similar parts.

Referring specifically to the drawings, 1 designates a discharge chamber having a discharge outlet 1 the chamber being shown in the form of a vertically disposed tube. The tube is fastened to, but out of communication with, a horizontally arranged cylinder designated 2, and depending therefrom is a suction tube 3, (see Fig. comprising a plurality of sections designated 4 screwed together as at 5, the lowermost section being preferably provided with any suitable form of trap as at 6.

munication therewith, are the vertically disposed suction cylinders 8 having at their upper ends removable caps 9. The ends of the cylinder 2 are projected slightly beyond the cylinders 8 and there receive removable closure caps 10. Said chamber 1 and tubes 8 communicate through the medium of connecting tubes 8. Chamber 1, cylinders 2 and 8 and one section of the suction tube 3 are preferably formed as an integral part of said integral structure, and has therein a suitable vent valve as at 11. A cross-head 12 is provided to be mounted adjacent the upper end of the cylinder and packing nuts 13 are adapted to screw onto the stuffing boxes 14 provided around the rod having extensible movement into and from the several cylinders.

Extending through the cross head 12, chamber 1, cylinder 2, and into the suction chamber, is a hollow rod designated 15 on which is suitably fastened a suction head 16. \Vithin the tubular rod 15 is slidably mounted a rod 17, the end of which extends somewhat below the end of rod 15 and has provided thereon a suction head 18. The suction head 16 may be of any suitable construction as to draw up the water on the up stroke and to permit the passage of water therethrough or past the same on the down stroke. As shown in the drawings, the suction heads 16 and 18 are made of suitable flexible material such as leather, so that their outer wall will yield inwardly on the down stroke to permit the upward passage of water between the head and wall of the tube bore. At the upper end of the rod 17 is fastened a cross piece 19 as by means of a set screw 20, which cross member is likewise fastened by a set screw 21 to a rod 22. To the lower end of the rod 22 and t0 the upper end of the tubular rod 15, are fastened cross arms 23 as by means of set screws 24 engaging the proper rods 15 and 22. On each cross arm 23 is fastened as at 25, rods 26 which extend and slide through the cross head 12, stufling box let, caps 9, and thence into the pump cylinders 8,.being provided at their ends with suitable upper suction heads 27, as are the suction heads 16 and 18, the suction heads 27 are constructed to draw up or elevate the water on the up stroke and permit the passage of the water therethrough, or past the same on the down stroke. To this end said heads 27 are preferably made of flexible material, such as lOQ leather, so as to yield similarly to the. heads 16 and 18. It might be here stated that the tubular rod 15 extends through the cross head 12, the central extension thereon, and the stufling box 14 of the discharge cham ber 1. Thus it will be realized that the eX- tensions, glands, and packing form suitable packing or stufiing boxes for the piston rods 26 and tubular rod 15.

In the cylinder 2 is mounted for lateral movement, a valve device adapted at times to cut off communication between tube 3 and cylinders 8, having at opposite ends, heads 28 being fastened together by means of a connecting member 29, being formed intermediate its ends to provide an elongated slot 30 through which the rods 15 and 17 pass, asbest seen in Fig. 2. I Within the chamber 2 is preferably provided, interior-1y extending annular flanges 31 which form abutments to limit the sliding movement of the heads 28.

Fastened to the cross head 12 are the arms 32 of an inverted V-shaped bracket to which is pivoted at its upper end on a pivot member 33, an operating lever or handle designated 34. The lever 34: has adjustably fastened thereto, clamp blocks 35 as by means of the set screws 36, to which blocks are pivoted at 37, pitman rods 38 also pivoted as at 39 to the cross arms 23.

In operation, the operating lever 31 is rocked or moved vertically through manual engagement, which action causes the alternate raising and lowering of the suction heads 27 and suction heads 16 and 18, it being clear that the pitman 38 of one cross bar 23, effects the movement of the rod 17 through its connection thereto by means of the'rod 22 and connecting member 19. The other pitman 38 by means of the other cross arm 23, causes the shifting of thetubular rod 15 and suction head 16 carried thereby, and which latter arm 23 also causes movement of the other piston 27 through its connection thereto by means of its rod 26. one set of connected upper and lower suction heads move simultaneously upwardly, the other set of connected upper and lower suction heads move simultaneously downwardly, the flexible construction of the heads 16 and 18 and 27 permitting the water to act against the same and contract them so that the water may gush or flow upwardly around the same. Thus while one set of upper suction heads and lower suction heads is on the up stroke creating a suctiion, through the pump and lifting the water, the

other set of upper suction heads and lower suction heads are on their down stroke. This action is alternate. By means of this arrangement there is always a suction in the pump which causes a continuous and even flow of water to pass through tube 3, cylinders 2 and 8, tubes 8, chamber 1, and

from the same through the opening at I When one of the'heads 27 moves upwardly on its up stroke and creates a suction through the pump, the valve device having the heads 28, is shifted longitudinally so that the head 28 adjacent the other cylinder, will cut ofi all communication therewith. Upon the down stroke of this same upper suction head the other upper suction head will start to move upwardly which will thus draw the adjacent head 28 away from its seat or flange 31, to permit the proper suction through the pump. l/Vhile the heads 27 descend, the valve heads 28 are in such position as to close communication between the proper chambers 8 and tube 3, whereby the water pumped into the tubes 8 is prevented from back-flow into tube 3, Likewise the construction of the heads 17 and 18 prevent the return of backfiow of the water after'being pumped past the same into tube 3.
