Fig. 6 is a view similar to Fig. '5 'of a further modification of the invention.

Referring to the 'drawings v in 'detail a .pair 'of spaced parallel well pipes ill and I2 are provided adjacent their lower ends with pumping cylinders M 'and 'F6 respectively. The lower ends fof -lthe pumping cylinders 14 and" |16 are respectively `eqlipl'iel with foot valves |8 and 2 0 which are disposed adjaoent the bottoni 'oi the 'well 'and below tll'e water level therein s'o that s V'the 'pistons v within iii-e eyliiiderslc reciprocate Wa-- ter will be drawn into the cylinders through the fro-Qt valves. Whileit is mit absolutely "essential the operation o i the device it is pieierredthat "the root Vvalves 18 and 26 be or the tall c liek ltype lflvil'g springs which advance the balls against the 'valve seats. A

Carried bythe upper ends or 'the well vpipes ip and 'l2 are upper pumping cylinders l22 and i254 respectively, the upper `'ends of whichopen into a "Gap 256 having a b'o'tt'ono 2'8 which entends bett/een the cyilnd'ers 22 and 24 and 7f orms asl 'p portiera "bearing "3 0 the purpose of which will b 'llibre hiele'aflel described. Muiltd fT rocking nlotion in 'the bearing '30 is a spherical bearing inc rilber =3 2 carrying oppositely 'extend-v ing arl'lls 31! and 136, the ends of whichreinote from the bearing member 32 y'are pivotally coluplea to piston rods `all and Aim respectively which Ain turn are vrespe'ctively connected to pistons 'E2 and i4 which work respectively in 'the cylinders .22 and Zas will be readily understood uponlee erenc'ejtb Fig. l. A radially extending arm A6 is carried by the bearing member 3.2 'and is colln'ected through a 'suitable link 48 to lever TBD which is pivotally supported at 52 o'n a bracket 54 carried by th'e cover 26. It 'will thus "b'e 'seen that as the lever '50 ismOVe'd about its pivot '152, the arm if will be cscillared thereby 'causing the. bearing Member 32 and 'arms S ll'd 3'6 t0 "O'S'l` late in the manner of a walking beam.

Carried by and extending between the lower cylinders i4 and I6 is a bearing 56 in which a bearing member of spherical formation 58 is mounted to oscillate. Like the bearing member 32, the bearing member 53 is provided with oppositely extending arms EI) and 62 which move in arcuate paths within cylinders I4 and I6 respectively and are connected through the inedium of connecting

rods

64 and 66 with pistons 68 and 'I0 which work in the cylinders I4 and I6 above the walking beam comprised of the bearing member 58 and the

arms

60 and 62. t will thus be seen that columns of water standing within the pipes IU and I2 between the

pistons

42 and 68 and between the pistons 44 and 'Ill will cause the pistons in their respective cylinders to move in unison.

Formed in the cylinder I4 are longitudinally spaced ports 'I2 and 'I4 which are located respectively `below and above the length of stroke of :s ,the piston 68, and formed in the cylinder I5 and extending through the side thereof in longitudinally spaced parallel relation are ports 'f6 and 78 which are respectively located below and above the limit of the stroke of the piston 'I0 in s vthe cylinder I6. It will thus be seen that water entering the cylinder I4 through the foot Valve IE thereof on the upstroke of the piston 58 will be expelled from said cylinder through the port 'I2 upon the down stroke of the piston 68. .Likewise water admitted to the cylinder I6 through the foot valve 2|) during the up stroke of the piston I0 will be expelled through the port 'I6 upon the down stroke of the piston 'IIL Mounted adjacent the well bottom near the cylinders I4 and I5 is a water box designated generally 'I'I which comprises a front wall lll, a

`rear wall Bil, side walls 82 and top and bottom walls 84.

This water box forms a hollow rectangular structure which is separated by a partition wall 85 into separate chambers or compartments A and B. A pipe nipple 81 communicates through the port 'I2 with the cylinder I4 and extends through the wall I9 of the water box 'I1 and into the chamber B, and carried by the end fof the pipe nipple 81 within the chamber B is a .check valve 88 which is designed to admit water from the cylinder I4 into the chamber B, but

arrest the discharge of water through the nipple 31 into the cylinder I4, A .pipe nipples@ com- 'municates with the cylinder I4 through the port 'I4 and opens into the chamber A as will be readily understood upon reference to Figs. 2 and 4. A pipe nipple 90 establishes communication between the cylinder I5 below the piston 'I0 and the chamber A `and is equipped with a check valve 92 (Fig. 4) which prevents the discharge of liquid from the chamber A into the cylinder I6. A pipe nipple 94 establishes communication through the port i8 between the cylinder I6 'above the piston 'I0 and the chamber B so that as the pistons 63 and 'I0 reciprocate in their respective cylinders I4 and I6, on the down stroke of the piston 68 in the cylinder I4, waterwill be lforced through the check valve 88 and into the 'chamber B, to be discharged through the nipple 94 and port 'I8 into the cylinder I6 above the piston 'IU working therein. Simultaneously through 4the walking beam coupling between the pistons `B8 and 1U, the upward movement of the piston I0 will fill the cylinder I5 with water through the check valve 20, so that upon the down stroke of the piston 10, the water contained in the -cylinder I6 will be expelled through the pipe nipple 90 and check valve 92 into the chamber A. The water expelled from the chamber A will find its way through the pipe 89 and the port 'I4 into the well pipe I0 above the cylinder I4 while the water which is expelled from the chamber B will find its way through the pipe nipple 94 into the well pipe I2 above the cylinder I6. rhe water thus expelled from the chambers A and B will form water columns in the well pipes I0 and I2 beneath the

pistons

42 and 44 in the

cylinders

22 and 24 respectively.

A water lbox designated generally 96 is carried by the well pipes I0 'and I2 adjacent the

cylinders

22 and 24 near the upper end of the well hole, and comprises front and back walls 98 and I respectively and side walls |62, y|34 and top and bottom walls I. A horizontally extending partition wall |08 extends across the water box 96 between the end walls |02 and |04 adjacent the top IIlS to dene a chamber E and a partition wall I I0 cooperates with the horizontal partition wall |03 in separating the lower portion of the water box 86 into separate compartments C and D. A water discharge pipe I S2 communicates with the compartment E through the wall Iil4 of the water box 96 and communication between the compartment E and the compartments C and D is established by check valves |I4 and IIB respectively which prevent the discharge oi water from the compartment E into the compartments C and D while permitting the flow of water from the compartments C and D into the compartment E for subsequent discharge through the discharge pipe II2. Establishing communication between the compartment C and the cylinder 22 below the piston 42 is a pipe nipple |I8 carrying at its end within the compartment C a check valve I2ll which prevents the egress of water from the compartment C into the cylinder 22 and a similar pipe nipple |22 establishes communication between the cylinder 24 and the compartment D below the piston 44, and like the pipe nipple IIS is equipped with a check valve |24 which prevents the discharge of water from the compartment D into the cylinder 24. A pipe nipple |26 establishes communication between the compartment D :and the cylinder 22 above the piston 42 and a similar pipe nipple |23 establishes communication between the compartment C and the cylinder 24 above the piston 44 working therein.

In the preferred form of the invention, the pipe II has communicating therewith a priming valve |30 which opens into the chamber C while the pipe |22 is likewise equipped with a priming valve |32 which opens into the chamber D. Each of these valves is equipped with a turning rod |33 and a handle |34 by means of which the valves may be turned to open or closed position.

In use, with water standing in the pipes I and I2 between the cylinders 22 and I4 and 24 and I6, it will be evident that when the lever 5i) is rocked vabout its pivot 52, the walking beam at the upper end of the well will reciprocate the

pistons

42 and 44 in their respective cylinders 2'2 and 24 so that the water within the pipes will react against the pistons 68 and 'I0 to cause them to reciprocate in their respective cylinders I4 and I6. As the water is drawn into the cylinder I4 through its respective check valve I8, the piston 'I0 descending in its respective cylinder I6 will force the water below it into the chamber A through the check valve 92, thus causing the water standing in the chamber A to `be discharged through the pipe 89 into the pipe II) so that it will ow upwardly, thus creating pressure on the column of water standing within the pipe I0 and forcing said water through the pipe nipple assises 'fiile and :cheek kvalve m trito the oompartment the end of the @cylinder 122 above 'the piston '42 "Working therein Iiilled water, the thereinto tiaig'h the check Valve |24 'wh and its way through the check naive 1116 .into the eonipainaent n to discharged through the .pipe ritz.. .as the 'lasten 44 :nieves downwardly within its cylinder 228., lpressure be exerted the piston .11 to downwardly and thereby the cylinder is through the onecle naive e8 to be the .'{Jit 16 80 and the valve V92 finto 'the chamber with 'the chamber .a filled with waiter, will be evident tira/tv the fioiving through the valve 8i' will force water out through the 89 into 'the 'cylinder N :and .pipe dil upwardly 'and into the ichamber throgiithe rppe i! 8 and chieck valve :|28 so time water 'drawn into the cylinder i|=6 through the fcheck valve :28 will be eventually discharged :ti-om the chamber .E `and discharge Spine di 22a`t1the topo thenrell.

Like the water box 96. the water box |86 is equipped with a discharge pipe |88 through which water pumped by the pumping mechanism is discharged for subsequent use. The structure illustrated in Fig. operates in a manner corresponding to the operation of the structure illustrated in Figs. 1 through 4 inclusive with the pistons |40 and |42 being actuated by the movement of the columns of water within the pipes |56 and |58.

In the further modication of the invention illustrated in Fig. 6 a pair of Well pipes |90 and 92 are provided at their lower ends with cylinders |94 and |96 respectively in which pistons |98 and 208 are mounted to reciprocate. A
