PUMPING ArrAnA'rUs.

Application filed July 21,

To all whom it mag concern; I

Be it known that I, IVA C. BELL, citizen of the United States of America, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Pumping Apparatus, of which the following is a specification.

This invention relates to new and useful improvements" in pumping apparatuses.

The invention has to do with that type of ,pumping apparatuses wherein the liquid is A further object is' to reduce lost motion and-to utilize substantially all of the applied power.

' Another object is to provide an apparatus for-elevating any liquid such as oil, water and the like with any fluid pressure such as steam, air and-the like.

A construction deslgned to carry out the invention will be hereinafter described to-- gether with other features of the invention.

The invention will be more readily understood from a reading of thefollowing specification and by reference to the accompanying drawings in which an example of the invention is shown, and wherein:

Fig. 1. is a diagrammatical vertical sectional view of an apparatus exemplifying the invention,

' I Fig. 2 is a cross-sectional view on the line 22 of Fig. 1, r Fig. 3 is a cross-sectional view on the line 3-3 of Fig. 1,

Fig. 4 is an enlarged view'of thevalve controlling head, and j Fig. 5 is a transverse sectional view taken on the line 55 of Fig. 4.

In the drawings the numeral 10' designates a transverse manifold from the top of which:

vertical cylinders 11 and 12 respectively ex tend upwardly; while vertical cylinders 11' and12' depend from the bottom of the'mani fold. The upper and lower cylinders are axially alined and while the lower cylinders j are-of less diameter, they are concentrically disposed with relation to the upper cylinders. Each lower cylinder has a check valve 13 in its bottom which is otherwise closed.

1924. Serial No. 727,307.

Liquid conducting

pipes

14 and 15 respec-.

tively' extend from the lower ends of the I lower cylinders to the upper ends of the upper cylinders, in crossed relation. The pipe 14 extends from the cylinders 11' to the cylinder 12; while the pipe 15 extends from the cylinder 12 to the cylinder 11. The

pipes

14 and 15 each have a check valve 16 at their lower ends.

In each upper cylinder is a piston head 17 connected by a piston rod 18 with a piston head 19 in the lower cylinder thereunder. The

pipes

14 and 15 and the rods 18 pass through the manifold. A deflector 20 is disposed in the manifold between the cylinders 11 and 12. At the upper end of each upper cylinder is an exterior by-pass pipe 21, having its ends entering the cylinder. Each pipe is long enpliliglfi to by-pass fluid from.

above to he reaches the upper purpose'of the y liquid below head 17 and thus maintain a solidicolumn of liquid between the heads- Unless some means was provided for restor- -pass pipe 21 is to supply 1 ing the liquid which .leakspast the piston rings, the solid column andbalance ,would be lost." Also these by-pass pipes afiord means for initially filling the cylinders between the

heads

17 and 19.

The

parts

17, 18 and 19 will be referred to as pistons and these pistons work oppositely, that is one is up when-the other is and when-fluid is force'dout of a lower cylinder by the .down stroke of the piston it will be displaced through the pipe 14 or '15 into the top of the upper cylinder, with which the pipe is connected.

excess of fluid from one uppercylinder will be forced throughthe manifold to the other upper cylinder, the excess being due to the greater capacity of the upper cylinders.

From; this it will be seen that the pistons are balanced and only enough pressure need has a plied onthe down stroke to displace t e ui Also upon-the down stroke of a piston the I A extends upwardly, while a pipe 23 extends 22 and 23 will also be filled. Thus any dls- From the top of the cylinder 11 a pipe 22 upwardly from the cylinder 12. These pipes enter a valve housing 24. The pipe 22 con- H nects with the bottom of av two-way valve case 25; while the pipe 23 connects with the bottom of a two-way valve case 26. A 'discharge pipe 27 leads from the case.25, while a similar pipe 28 leads from thecase 26. A fluid pressure supply pipe29 has branches leading to the'cases and entering at points spaced apart about ninety degrees.

In the case 25 is a rotatable gate 25' and a similar gate 26' is mounted in the case 26. The discharge pipes lead from the cases at substantially ninety degrees from the'entrance of the

pipes

22 and 23. The gates have their shafts 31 connected with arms 32 exteriorly of the housing (Fig. 4). These enters the valve cases and 26. The gate ,7 26 cuts oil the escape of the fluid .from the arms have their upper ends pivoted to a connecting bar 33, whereby-they are swung in unison. A shifting lever 34 'is fulcru'med on a stud 35 on the side of the housing 24 and has a slot 36 at its upper end receiving a headed pin 37 As is shown in under pressure supplied from the pipe 29 case 26, but permits the elevating liquid from the pipe 23 to'discharge through the pipe 28. The fluid under pressure from the case 25 passes into the pipe 22, the discharge 27 being cut oil by the gate 25. The fluid pressure depresses the piston in-the cylinders 11 and 11.

. When the piston starts down as described the valve 13 at the bottom of the cylinder 11' is closed and the valve 16 is opened, thus the liquidbelow the head 19 in said cylinder is forced out through the pipe 14 into the top of the cylinder 12. The liquid below the head 17 in the cylinder 11 fills the cylinder 11' above the head 19 as the piston descends, but as the capacity of the cylinder 11 is considerably greater than that of the cylinder 11', there will be an excess or surplus of liquid which will be displaced into the manifold and the cylinder 12. This displacement will be suflicient to counterbalance the piston in the cylinders 12 and 12', which will be elevated in proportion to the descent of the first piston. v I

As the piston in the cylinders 12 and 12' is elevated it will displace the ffluid above the head 17 in the cylinder 12 as well as the. liquid entering from the pipe 114. I This' .liquid will be elevated in the ipe 23 and discharged from the-pipe 28. ile the piston in the cylinder 11 is descending the pipe 15 having been previously-filled, will be so held. While the pisten-iinrt egcylinder 12 is rising it will draw in liquld 'tlirough the valve 13 in the bottom of said cylinder. At all times a solid body of liquid-will be pres- Fig. the elevating fluid lent on both sides of the piston heads 17 and 19 and they will counterbalance. The pipes placement of the liquid will also move the the lower slotted end of'the lever 34. The

left hand end. (Fig. l) of the cylinder is connected with the pipe 22 by a pipe 41; while a pipe 42 connects the pipe 23 with the right hand end of the cylinder. Each of the

pipes

41 and 42 includes a spring pressed pressure valve 43.

As is shown in Fig. 1 the piston head 39 isat the left hand end of the cylinder 38. The pipes41 and 42 are small and the fluid entering said pipes willunseat the valves 43 at a predetermined pressure. So long as liquid is being elevated in the pipe 23 atpipes 41 full capacity the pressure in the and '42 will be substantially equal and the piston will be held in the cylinder 38 as is shown, but when the pressure in the pipe 22 becomes greater at the endbfthe up stroke of the piston in the cylinder 12, the fluid from the pipe 41 will enter the right hand end of the cylinder 38 and displace the piston head 39, thus shifting the lever 34 and valves.

It is pointed out that the pipes and cylinders of the pump need not be arranged as shown in the drawings and any suitable and 1' operable arrangement may be made as the conditions of the wellmayrequire. What I claim, is: 1. In a balanced fluid column pumping apparatus, a pair of vertical containers connected for displacing fluidintermediate their ends from one to the other and also connected for displacing fluid from the lower end of each to the upper end of the other, andoppositely disposed pistons, one of the pistons being suspended in one container and the otherpiston disposed in fluid from one column to theotherlto elevate the fluid inv the last named column.
