To all whom it may concern.-

Be it. known that I, EUGENIO K. HAYES, residing at Kewanee, in the county of Henry and State of Illinois, and a citizen of the United States, have invented a new and useful Improvement in Force-Pumps, of which the following is a full description, reference being had to the, accompanying drawings, in which Figure is a front elevation, Fig. 2 a side elevation, Fig. 3 an enlarged sectional elevation, of the cylinders and piston and receiving-chamber, Wit-h the lifting-rods and the tube broken oil? and partly in section; Fig. 4, atop view of the receiving-chamber; Fig. 5, a bottom view of the receiving-chamber; Fig. 6, a detail, being a side elevation of one of the cylinders partly broken out and the cap-plate removed; Fig. 7, a bottom view of one of the cylinders with the cap-plate removed; Fig. 8, a bottom view of one of the cylinders with the cap-plate in position; Figs. 9 and 10, a top view and a side elevation, respectively, of the walking-beam; Fig. 11, a detail of the handle; Fig. 12, a detail of the cap or fulcrum on which the walking-beam is mounted Fig. 13, a detail of the upper end of the main pipe; Fig. 14, a plan View of the stand; Figs. 15 and 16, a side elevation and a top view,'respectively, of the guide for the piston-rod; Fig. 17, a detail of the upper end of the piston-rod for the attachment of a windmill-rod;'Figs. 18, 19, and 20, details of the clamp connecting the piston-rod with the windmill-rod; Figs. 21 and 22,'side elevations showing a support for the discharge-pipe; Figs. 23 and 24, a side elevation and a top View of a walking-beam into which the handle is slipped.

The objects of this invention are to construct a force-pump, which can be made double-acting or single-acting, as may be desired, and which can be used with one cylinder operated from a handle and the other from a windmill or other motive power, and to improve generally the construction and operation of force-pumps; and its nature consists in the several parts and combinations of parts hereinafter described, and pointed out in the claim as new.

In the drawings, A represents the cylinders, each formed of an annular wall having at the lower end a chamber A, the bottom of which is perforated with a number of holes a, and in contact with the bottom plate on the inside is a screen a for preventing the entrance of sand and other sediment into the chamber and cylinder. The upper wall of the chamber A is provided with an opening ct, leading into the cylinder A, and this opening is controlled, as shown, by aweighted flap-valve a". The upper end of the cylinder A is encompassed by a cap ','through which is an opening for the passage of the piston-rod.

B is the piston-rod, having a longitudinal hole its entire length, and the lower end of this tube or rod carries a piston B, formed,

as shown, of a packing b, inclosed between a rim or flange b on the tube B, and a nut screw-threaded onto the end of the tube.

C is a brass packing-ring,into which the upper ends of the tube or piston-rod B are screwed, and this ring 0 is screw-threaded into the receiving-chamber, the end 0 of the ring forming the seat for a weighted fiapvalve 0. Two cylinders and pistons are used, each similar to the other in its construction, and, as shown, the weighted flap-valves C for the tubes or piston-rods B; are both attached to the same piece of flexible'material O, which material is secured to the bottom of the receiving-chamber by a boltc and a washer c, as shown in Fig. 3.

D is the receiving-chamber of an elongated rectangular shape, having in the bottom two openings to receive the packing-rings C of the respective tubes B, and allow the water to pass from the tubes alternately into the chamber, making a continuous supply, and this chamber on its top plate is provided with a boss d, with a central screw-threaded opening leading into the chamber. The chamber D is of sufficient length to locate the cylinders side by side Without interference with the working of each, and its width is nearly the same as the diameter of the cylinder.

E is the tube leading from the supply-chamber D to the discharge-spout and extending up beyond the point of attachment of the discharge-pipe to form an air-chamber. This tube can be made up of sections of pipe secured together by suitable couplings, and its length will depend upon the depth of the well or other reservoir with which the pump is to be used.

F is the discharge-pipe attached at its lower end to a coupling E on the tube E, and having a discharge-nozzle F.

G is a base-plate, through the center of which the tube E passes, and having at one side a boss or annular projection f, with a circular opening for the passage of the discharge pipe F, and, as shown, the discharge-pipe is locked by a set-bolt f, and, if desired, set-' bolts can be screwed into the collar at the center of G for locking the tube E.

II represents the rods for reciprocating the cylinders A, a rod being used for each cylinder, and each rod having at its lower end a fork II, the arms h of which pass through ears g, one on each side of the cap A", and ears g, one on each side of the chamber A, and 011 the rods h of the fork II are secured collars h, to abut against the top of the plate or cap A, and the lower end of each rod h is screw-threaded to receive a nut h, by means of which the chamber A and the cap or plate A can be drawn snugly against the ends of the cylinder A, forming a close connection around the ends of the cylinder. The fork ll furnishes a connection with the rods h, and also the means for securing the heads to the cylinder, and this fork presents an effectual obstacle against the unscrewing of the parts by which the cylinder-heads might become loosened when the rods H are attached to their operating walking-beam or handle.

I is a guide-block attached to the tube E and projecting outward on each side in line with the rod H, and having at each end a hole for the passage of the rod, so that the rod will not bend or buckle in use.

J is a walking-beam mounted 011 the upper end of the tube E. This walking-beam has a longitudinal slot J to receive the end of a support J" on the end of the tube E, and to which support the walking-beam is pivotally connected by a suitable pin or bolt 1', and, as shown, one end only of this walking-beam is provided with a socket for the reception of a handle; but both ends could be socketed, if so desired. One rod I'I steps or terminates at its connection with the walking-beam end, the connection being, as shown, by means of a pin or pivot j passing through the end of the beam and the rod 11. The other rod His flattened at its upper end and made to pass above the walking-beam for the purpose of attaching the pitman operated by a windmill or other motive power, and this rod H has its end connected to the walking-beam by a bolt j, which can be removed to disconnect the rod from the walking-imam and leave it free to be worked by the pitman. The rods H are further guided and maintained in a direct vertical line by slots 6, formed in the stand or support G.

K is a handle secured to the end of the walking-beam J, the end of the handle entering the socket it of the walking-beam.

L is a clasp provided with cars 1, through which and the upper end of the projecting rod H a bolt or pin can be passed to attach the clasp to the rod, and to this clasp is bolted or otherwise secured the end of the pitman operated from a windmill or other power. (Not shown.)

In use, when the pump is operated by handpower, the operator, by takinghold of the handle K, reciprocates the cylinders A through the rods II, one cylinder rising as the othcris falling, and such movements of the cylinders form a double-acting force-pump by which the water is lifted into the chamber 1), thence passing into the tube E and out through the discharge-pipe F. The downward movement of each cylinder A forces water through the openings (and screen, when used) into the chamber A, and thence into the cylinder A through the valve a", which is thrown up, the valve 0 at the top of the pipe of the descending cylinder being thrown down. At the same time water is discharged into the chamber D through the other cylinder which is being lifted, the valve a" of such cylinder being closed and the valve 0' open, and, as shown, the opening of the valve 0' is stopped or limited by projections (1' depending from the top of the chamber D 5 and this filling of the one cylinder and discharging of the other will occur at each up-and-down stroke of the handle K, making the discharge a continuous one.

The pump can be used as a single-acting pump, by disengaging the rod H, having the flat end, so that the movement of the handle K and walking-beam J will operate but the one rod, producing a filling and discharging of a single cylinder; and both cylinders can be operated independently by disconnecting the rod H with theflat end from the walking-beam and connecting it to a windmill-pitman or other motive power, leaving one cylinder to be operated by the handle and beam and the other by the pitman, thus enabling the pump to be used as an attachment to a windmill or other motive power, and at the same time to be operated by hand independently, so that in case the mechanical device operating one rod becomes useless the pump can still be 01% erated through the other rod by hand.

The employment of the cylinder to do the lifting, instead of the plunger or piston, i11- creases the simplicity and power of the pump,

in that no packing-box is required around smaller cylinders to be used for the samelift, and by having the cylinders operated through detachable rods two single-acting pumps are had, each working independent of the other. The location of the rods which reciprocate the cylinder outside of the pipe through which the water passes leaves the entire inside measurement of the pipe free and clear for the passage of the water, thereby enabling an inch pipe to be used with a greater capacity than a much larger pipe, in which the plunger would be used. The rods which operate the cylinders also through the fork at the lower end serve to hold the heads of the cylinders to the body, and when these rods are secured at their upper ends to the walking-beam it will be seen that no turning can be had to loosen the holding-nuts and disconnect the rods from the cylinders or unfasten the cylinders themselves; and the cylinders being located in the bottom of the well or other reservoir are always submerged, so that the pump is kept primed, all of which features make the pump very reliable and effectual in use.

The pump shown in Figs. 21 and- 22 is of the same general construction as that already described, except that a support G is provided running from a socket on the stand G to a band G, which band clasps or encircles both the tube E and the tube F, and the object of this bracing, furnished by the rod G'- and band G, is to hold the tubes against vibration in use.

The walking-beam shown in Figs. 9 and 10 is formed of a single piece having a longitudinal slot J and a screw-threaded socket is to receive the screw-threaded end of the handle K. This walking-beam could be made in two pieces, as shown in Figs. 22 and 23, the pieces being held apart by interposed pieces to form the slot J, and instead of the handle K being screwed into the walking-beam it can he slipped into the socket is and held therein by tightening-bolts 76', which bolts also at one end serve to connect the two parts of the walking-beam J together, the other end of such walking-beam being connected by a minates at its attachment with the handle,

the handle can be reversed and connected with the other rod, and still have a singleacting pump operated from the handle, and the breakage of the rod to which the windmill is attached can be remedied by reversing the handle and connecting the other rod with the pitman and it will be seen that a doubleacting force-pump with reciprocating cylinders both working at the same time is had, and also a single-acting force-pump, either cylinder being capable of working independently of the other, either by hand or from a windmill or other motive power; or one cylinder can be worked by hand and the other by windmill or other motive power independently, producing the effect of a double-acting force-pump the cylinders of which are operated by independently-acting power.

The rods H each have a connecting-nut m,

l by which the attachment to the walking-beam can be readily changed.

What I claim as new, and desire to secure by Letters Patent, is-

The combination of the cylinders A A, the

tubes B B, provided with pistons B B within said cylinders, the valve-controlled receiving chamber D, the tube E, extending upwardly from said chamber, the beam J, fulcrumed in a support on the upper end of said tube, and the detachable rods H, one of which is 6X- tended above the beam for connection with a wind-wheel, whereby the pump may be made either double-acting or single-acting and the opposite sides be operated either bythe same power or one by hand and the other by windwheel, substantially as described.
