Specification of Letters Patent. Patented Dec. 141i, 11915;

Application filed January 21, 1915. Serial No. 3,502.

To all whom it may concern Be it known that 1, FRANK FOLEY, a citizen of the United States, and a resident of Mayview, (Gillett post-otfice,) in the county of Arkansas and State of Arkansas, have made certain new and useful Improvements in Pumps, of which the following is a specification.

My invention is an improvement in pumps, and the invention has for its object to provide a pump having a double piston or plunger together with mechanism for operating the pistons or plungers in opposite directions, and wherein a particular form of piston or plunger is provided, oli'ering'a minimum resistance to the up'flow of the water on the downward stroke of the piston and a maximum of lifting power on the upstroke.

In the drawings: Figure 1 is a side view of the improved pump with parts in section, Fig. 2 is a partial section showing the guide mechanism, Fig. 8is a top plan view partly in section of the block to which the plunger rods are connected, Fig. 45 is a top plan view of one of theplungers, Fig. 5 is a side view of the same, Fig. 6 is a bottom plan view of one of the plungers, and Fig. 7 is a vertical section of the said plunger.

The embodiment of the invention shown in the drawings comprises a pump consisting of a cylinder 1 having an outlet pipe 2 near its top, for permitting the discharge of the water raised and a pair of pistons or plungers 3 and t are arranged within the cylinder, the said pistons being mounted to move in opposite directions and the rod 5 of the piston 3 is hollow or tubular to permit the passage of the rod 6 of the plunger 4. The operating mechanism for the plungers or pistons consists of a standard 7 having journaled thereon walking beams 8 and 9, the beams being journaled intermediate their ends, the beam 8 at the top of the standard and the beam 9 near the top but spaced apart from the beam 8 in such manner that the The standard 7 is secured to a suitable base 10, the standard having laterally extending lugs 11 resting upon the base and secured thereto by bolts and nuts 12.

ri'suitable motor (not shown) is provided for operating the pump and the motor is connected to a pulley 18 suitably mounted adjacent to the standard by means of a belt 1 1. The pulley 13 is secured to a shaft 15 journaled in the bearing brackets 16 at the opposite end of the base from the cylinder and on the opposite side of the standard 7, each bracket having laterally extending lugs 17 resting on the base and secured thereto by bolts and nuts 18.

The shaft 15 is provided at each end with i a crank arm 19, the arms being secured to the shaft by keys 20 and the arms extend in opposite directions, as shown. Each arm is connected to a walking beam by means ofa link 21 and 21 respectively, the link 21 being connected to the beam 8'wliile the link 21 is connected to the beam 9. It will be evident that when the shaft is rotated the walkbeam is connected to a piston or plunger the pistons will be reciprocated. Since the crank arms 19 extend in opposite directions the walking beams will. be oscillated in op- .ing beams will be vibrated and since each posite directions. The pump cylinder 1 eX tends above the base 10 and each walking beam 8 and 9 is in fact composed of two levers spaced apart from each other and rigldly connected.

As shown 1n Fig. 2 each of the levers constituting the beams 8 or 9 as the case may I be is connected at the end remote from the shaft 15 with one end of a link 22, the other end of the link having an opening for receiving one of the journal pins 23 of a connecting block connected to the adjacent plunger rod. This block is sectional, each journal pin 23 being threaded into the socket of a sectional bearing 24. The sections of the bearing embrace the upper threaded ends of the rod 5 or 6, as the case may be, and the sections are clamped together on the rod by bolts and nuts 40.

Above and below the bearing sections,

nuts 41 are threaded onto the rods, and itlink 22, the links being arranged at the outer sides of the sockets of the bearingsections 24: and then through a collar 12, and a flange wheel 4-3 is journaled on the outer end of each journal pin. The collars 42 act as spacing members to space the wheels 13 apart from the links 22, and these wheels are arranged wlth the flanges outward, as

shown more particularly in Fig. 2. Each wheel 42 moves between the members of'a palr of spaced guide bars 44, .a pa1r; .'of gu de bars being arranged at each side of the cylinder and extending outwardly from the base 10. The bars are rigidly connected in any preferred manner and the inner members of the pairs, that is the bars adjacent to the standard 7, are braced against the standard by upper and lower braces 45.

Each brace has its ends bent laterally as shown at 46 and fitting against the adjacent bar or standard and the angular portions are secured to the bars or the standards in any suitable manner. The flanges of the wheels 43 prevent longitudinal movement of the journal pins 23, thus holding the connecting blocks which are in effect cross heads to a rigid up and down movement. With this arrangement there is no lateral play of the plunger rods at their upper ends, and the plunger rods and plungers are constrained to a true vertical movement.

The plungers 3 and 4 are similar, differ ing only in that the upper plunger has an opening at its top and that the rod connected thereto is tubular. Each plunger is coneshaped and they are arranged in the cylinder with thelr bases downward. The outer wall of the plunger is stepped, as shown in Figs 4 to 7 inclusive, and each piston consists of bars 25 secured to the rod 5 or 6, as the case may be, in spaced relation and 'at right angles of 90 with respect to each other. The bars extend downwardl and outwardly, the upper end of each bar being beveled as shown at 26 to fit against the periphery of the adjacent rod, and the outer side edge of each bar is provided at spaced intervals with vertical faces 27, the bottom of one face being connected with the top of the preceding face by an inclined face 27. The vertical faces 27 and the inclined faces 27*" of the bars are in register and a cylindrical ring 28 is secured to the bars at each series of vertical faces. Each series of inclined faces of the bars forms a. support for a series of valves 29, each valve being curved transversely to fit against the faces and having its side edges shaped to fit against the side edges of the adjacent valves and the said valves close against the inclined faces of the bars. Each valve is hinged to the next lower ring 28, and the ends of the valves are beveled, as shown at 30 at each end, to fit against the upper edge of the next lower ring 28 and to fit against the outer face or periphery of the next upper ring 28. a

"A series of hinge leaves 31 is connected With each ring 28 except the lowermost and each valve is provided with a hinge leaf 32 at its center, the leaf being connected to thecadjacent leaf 31. The hinge leaves are connected by pintles 33 and a spring 34 is secured to each leaf 31 at one end, the free end of the spring beingspacedoutwardly from the outer face of the adjacent leaf an upper portion inclined inwardly slightly,

the arrangement being such that the valves cannot open into vertical position as indicated in dotted lines in Fig. 7. The lowermost ring 28 has its lower edge beveled on the inner surface thereof, as shown at 36, and the outer surface is provided with an annular groove 35 for receiving a packing ring 37. The valves 29 at the lowermost rings are hinged to the upper edge thereof directly, the hinge leaf 32 of the said valves being pivoted to the ring instead of to an other hinge leaf. The springs 34 are also secured to the upper edge of the ring at this point to leave the periphery of the ring uuobstructed.

In operation, when the crank shaft 15 is rotated the walking beams will be oscillated in opposite directions to cause the plungers or pistons 3 and 4 to be simultaneously reciprocated in opposite directions, one piston making the up stroke when the other makes the down stroke. As each piston moves downwardly the valves 29 thereof are moved upward by the water which passes freely between the rings 28 and through the openings between the rings. The rings having their wide dimension vertical offer but slight resistance to the passage of the water. On the up stroke of the piston the valves close against the inclined faces of the arms and the water above the piston is lifted with the piston.

The springs 34 limit the opening movement of the valves to a position a little less than vertical, so that on the up stroke of he piston the action of the water will swing the said valves inwardly to closed position. The plunger rod 6 of the lower piston passes through the tubular rod 5 of the upper piston and since the two rods are held to a rigid up and down movement there can be no interference between them.

I claim:
