BALANCED PUMP.
Application l'ed May 12,
The invention relates primarily to de ep well pumps and has for its object to provide an exceptionally simple and inexpensive, yet an efiicient and reliable pump of this character which, with a predetermined stroke, will elevate an unusually great amount of water, and is so balanced that very little power is necessary for effecting its operation.
ldith the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawing.
Fig. 1 is a side elevation partly in section on line 1-1 of Fig. 3.
Fig. 2 is a fragmentary side elevation partly in section looking in the direction indicated by the arrow A of Fig. l.
Fig. 3 is a horizontal sectional view on line 3--3 of Fig. 1.
Fig. 4 is a detail vertical section on an enlarged scale., as indicated by line 4-4 of Fig. l.
The pump embodies two strings of tubing 5-5, appropriately guided by rollers or other desired means 6 and connected by pitmen 7 to a. walking beam 8 which maybe operated in any desired manner to produce opposite reciprocation of said strings of tubing.
For the strings of tubing 5-5a, two pump cylinders 9-9l respectively, are provided., said cylinders being rigidly connected with the tubing by appropriate branched {couplings 10--10L provided respectively with inlet and discharge valves 11-12 and 11a-12a.k Slidable in the cylinder 9, is a piston 18, and a similar piston 13a is slidable in the cylinder 9d. These pistons are provided with upstanding piston rods 14k-14a whose upper ends are turned horizontally and provided with contractible collars 15---15a respectively. Collar 15a is secured around the tubing string 5 and collar 15 is secured around the tubing 5. Hence, reciprocation of the tubing string `5 serves to reciprocate the piston 13a associated with the string of tubing 5, Similarly, reciprocation of this string of tubing 5 reciprocates the piston 13 associated with the tubing string `5. Hence, I obtain a double ac-l tion from the pump, as when either piston is moving in one direction, its co-operating cylinder is moving in the opposite direction. Moreover, the two strings of tubing being constantly filled with water, effectively balance each other and hence only a small 192s. serial No. 277,298.
amount of power is necessary to operate the pump. With a stroke of given length, the pump will elevate a great deal more water or oil. than .pumps heretofore devised with the same stroke, and this increase of efficiency is obtained with the expenditure of less power.
Excellent results may be obtained from the general construction shown and described and such construction may therefore be followed. However, it is'to be understood that the present illustration is primarily for illustrative purposes, and that within the scope of the invention as claimed, numerous variations may be made.
I claim 1. A pump comprising two strings of tubing, two cylinders rigidly connected with said strings respectively, inlet and discharge valves yfor said cylinders, pistons in said cylinders co-operable with said valves in effecting fluid flow through said strings of tubing, means for oppositely reciprocating said strings of tubing, and means directly connecting each string of tubing with the piston associated with the other string.
2. A pump comprising two strings of tubing, two cylinders offset from and rigidly connectedv with said strings respectively, inlet and discharge valves for said cylinders, pistons in said cylinders co-operable with said. valves in effecting fluid flow through said strings of tubing, piston rods rising from said piston to points above said cylinders, means securing the piston rod associated with each string of tubing to the other string, and means for oppositely reciprocating said strings of' tubing.
3. A pump comprising two strings of tubing. two cylinders offset from and rigidly connected wlth said strings respectively, inlet and discharge valves for said cylinders, pistons in said cylinders co-operable with said valves in effecting fluid iiow through said strings of tubing, piston rods rising from said pistons to points above said cylinders, the upper ends of said rods being laterally directed and having contractible collars, the
collar of the rod associated with each string of tubing being secured around the other string, and means for oppositely reciprocating said strings of tubing.
In testimony whereof I have hereunto affixed my signature.
