a modified formofthe air conchanism with parts shown in sec- In the drawing, reference character l() represents the bore of a well in which a portion of the pumping apparatus is placed, this portion consisting of cylinders 11A and '12 mounted in superposed fashion butseparate from each other. The cylinders are provided with integral partitions 13 and 14 respectively dividing the cylinders into two parts,

the larger of which forms Vthe inlet sideand the smaller partition 13 in cylinder llextends the. full length and completely separates the inlet from the outlet side. In the lower cylinder 12, the partition 14 extends downwardly. but

the discharge side thereof. The

does not reach the bottom thereby allowing liquid to flo w from one side to the other. The' cylinders are provided`with narrow4 inlet openings 1 5 and 16 respectively extending almost the entire length of the cylinders, each provided with inwardly extending valve seats on wh ich rest flaps 17 and 18 these being ing fluid to the cylinders from a control mechhinged at 19'and 20 and operating within the cylinders. The length of the cylinders may vary and in order to insure quick filling any number of additional inlet valves may be used, h5 A pipe 21 connects the discharge pipes of the two cylinders and is provided Vwith a one-way lvalve 22 which permits' liquid to pass from the discharge side-ofcylinder 12 s p to the discharge side of cylinder 11 and out- 60 ward to a common discharge pipe23to any desired p-oint, this pipe 23 being connected to thevupper end V of the discharge side of cylinder 1 1. 4

A pipe 24 is connected tothe bottom of cylinderll and is'joined to pipe 21 at a point 25 intermediate the valve 22 and the lower end of the discharge side ofcylinder 11 and is provided withya one-way valve 26, similar y tovalve 22, permitting liquid to pass fromthe 70 cylinder llto pipe 21, hence outward through the common discharge 23. Pipes 27 and 28 connected to the upper. ends of the cylinders 11 and-12respectively and convey the operatanism as will now be described.

h The control mechanism consists of a valve structure 29,. The upper portion 30 is provided with anoutwardly extending flange 31 on its lower edge and an arm 32,. The lower portion 33 is cup-like inl .structure and has a iiange'34, corresponding to iange 31, on its upper e-dge by which the parts 30 and 33 are secured together by any suitable means. The center portion 35.01 the valve is nested in the lower portion 33 and provided with packing rings 36 to form a tight but rotatable connection withrespect to the upper andlower portions.A The center portion is provided i with inlet passage ways 37'and 38 each dia- 90 metrically opposite exhaust ports 39:and'40A respectively. The inlet passages extend through this portion and in line with the cor-y` responding passages in the upper and lower 9,. portions' depending on the position of the center portion). The exhaust ports extend partially into the center portion and are turned at right angles to the outside edge. Corresponding ports 41 and 42 are'bored in the lower section to conform with the exhaust ports 40 and 39 respectively.

A lever 43, extending through a slot 43 in the lower portion 33 is connected to the center portion and is operated by a rod having a slotted bar 44 on one end and connected at the other end to a piston 45 operable in a cylinder 46. The piston 45 is operated by means of compressed air from the pipes 27 and 28 and conveyed to each side of the piston by pipes 46 and 47. The needle valves 48 and 49 control the flow of the air to the cylinder 46.

A pin 50 secured to thelever 43 extends into y the slot in the bar 44 serving as a connection between the rotating portion 35 and the piston 45. A pin 51 of greater length than Ypin 50 is'xed to the lever 43 and spaced from the slotted'bar 44 at a distance to move without engaging the bar. A similar pin .52 is secured to the arm 32 and a spring 53 is connected between the last named pins serving to snap the mechanism back and forth as the spring moves in and'out of parallel alignment with the lever 43.

The lower portion ofthe valve structure is connected to pipes 27 and 28 and the upper portion'to p'i es 54 and 55 which merge into a single supp y pipe 56 connected to av tank 57 of compressed gas or air and supplied by the pipe 58 from a compressor not shown.

Inthe modified form Fig. 5 a valve operating on the same principle as that just 'described is 'shown but of slightly dil'erent structure. The valve consists of a sliding central portion 59 provided lwith passages 60 and 61 and exhaust'ports 62 and 63. a The upper section 64 p and the lower section "65 are secured together by an'ysuita'ble means. A bar 66 is secured or 'madeintegral with the sliding section 59 and is provided with a pin 67 at its free end. The slotted end 68 of the piston rod 70 engagesthe pin 67, .said slotted end68 being actuated by a piston 71v on the piston rod 7 01 operating in cylinder 72. The piston is operable by compressed air4 or gas from lines 73 and 74 connected to line 75 and 76 respectively which carry air to the main cylinders in the well from the control valve. Pipes 77 and 78 supply the main valve with compressed air from a suitable supply.

A curved bracket 79 is mounted on the upper section 64 of the vvalve and is provided with a link 80 pivoted to its free end Aa't'81.v

The link 8O is provided with a: slot 82 which engages -a ypin 83 on the bar 66. The free end of the link 80 is connected to a point 84 of the bracket 79 by a spring 85 in a manner to move with the bar 66 t'o the right or left as the case may be and cause afsnapmovement ofthe bar 66 as the .spring 85 moves in Vand out'of parallel alignment with respect to the link 80.

The operation of the above described apparatus is as follows Compressed air or gas flows from the supply tank or any suitable source through the main pipe line 56 and hence to the valve which is in the position as indicated by Fig. 2. The passage way 38 is in line with the pipes 53 and 27 permitting the operating fluid to flow into the pipe 27 forcing the valve 17 shut and the liquid which is in the cylinder 11 through the pipe 24, pipe 21 and then outward through the pipe 23. Valve 22 prevents 'the liquid from entering the cylinder l2.

VAt the same time part of the compressed air enters the Ipip-e 46V and the piston 45 is gradually moved to the right forcing the slotted bar 44 carrying the lever 43, and rotating the section 35 slowly in a counter-clockwise direction until the spring has'passedfa line parallel with the lever and then it will snap to its extreme position due to the vaction of the spring. As the compressed air enters the cylinder l1 the valve 18 lin the cylinder 12 opens, the incoming water forcing the trapped air upward through the pipe 28 which is in line with the exhaust port 40. As soon as the piston 45 has reached the position opposite to that shown in Figure 2 the passageway 37 Vis then in line with the pipes 28 and Y55, the exhaust port y39 lines up with the pipe 27. Air is forced through the pipe 28 to the cylinder 12 forcing the valve 18 shut and the uliquid outwardly through the discharge side into the pipe 21 and thence to the discharge pipe 23. vThe valve 26 prevents theliquid from entering the cylinder 11. Meanwhile the incoming water against the valve 17 in the cylinder 11 forces the air out of this cylinder through the ,pipe 27 to the exhaust port 39, thus completing one pumpingstroke of the pumping apparatus and which always insures constant flow of water from lthe cylinders. The rapidity of operating is controlled by the needle valves 48 and 49 to the valve operating piston. The form shown in Figure 5 operates substantially the same in principle excepting for alsliding horizontal rather than rotatable control valve.

It will be obvious to those skilled in the art that various `changes may be made in my device without departing from the spirit of the .inventionand therefore I -do not limit myself to what is shown in the drawing and described .inthe specification, but only as indicated by the appended claims.
