iclaim. (caso-54.5)
Application December sociated therewith vertically disposed cylinders and pistons operating therein which are connected to the pump rod in the 'I'he invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompany'ing drawing and specically pointed. out in the appended claim.
In describing my. invention in detail. reference will be had to theaccompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in' which:
Figure 1 is a side elevational view of a hydraulic pump jack embodying the features of the present invention.
Figure 2 is a top plan view thereof. Figure 3 is an end elevational view.
Referring to the drawing for a. more detailed.v
the improved hydraulic pumpA jackA is generally designated by the reference description thereof numeral 5 and includes a pair of horizontally disposed parallel extending members 6v which are positioned on the ground adjacent the well caswell whereby the the same being connected by means oi.' a cross b ars II.
connector bar I2, as indicated at 28, said plunger 4 ing 1. The members s are united by means of 8 and 9, respectively. connected by any desired means. Members 6 adjacent the are formed with enlarged portions III through which bars II. are
lslidably mounted. Connector bars I2 and I3, re-
spectively, are attached to each end of the slide bars II the same being held thereon byJmeans ofnuts, or the like, I4. `As best shown in Figure 2 ofthe drawing, the slide bars. II are mounted directlyabove themembers Gand are held spaced therefrom by means of the connector bar l2. Attached to the forward connector bar I3 is a pull rod I5 leading to a source of power, not shown, and Arepresenting actuating means whereby reciprocation may' be imparted to the slide'bars I 'I for actuating the plunger I6 within.
or the like, 26. The polish W. Bragg.
the horizontally disposed The cylinder I'I is disposed substantially centrally of the members Band is held on one end by means of the transverse beam 9, said cylinder adapted to contain a quantity of fluid such as oil, or the like. The other end of the cylinder I1 is connected with a substantially Y-shaped head Iuformed with a conduit I9 in communication with saidl cylinder. The head It is formed with end blocks 20 which extend beneath enlarged portions I inwardly from the ends of the side members 6 and are attached thereto.
Vertically disposed 4cylinders 2l and 22 are mounted on the head I8 and are in direct communication with the conduit I8. Pistons 23 and 24 are mounted within the cylinders 2l andv 22 bar 25 held on said pistons by means of nuts.
rod 21 which is actuated for pumping the well 'I is connected to the cross bar 25, as indicated at 28, whereby movement of the pistons 23 and 24 will actuate the bar 2li In the operation of the device, power is applied to theplill rod I5 for Since the plunger I8 is attachedto the will reciprocate within the piston I1 to force theiiuid through the conduit I8 into the vertically disposed cylinders 2| and 22. The force oi' the iluid will raise the pistons 23 and 24 and the cross bar 25 for actuating the polish rod 21. As best shown in Figures 2 and 3 of the drawing.
the .shape of the head I8 permits it to surround -the well casing. y'l and the entire pump jack 5ba-n be moved to various positions within the radius of the horizontally disposed cylinder- I1. Due to' the formation of the pump jack, the head will also ilt around the well casing 1 in such a manner as to arrange the upright cylinders 2| andi 22 at diametrically opposite sides of the polish rod 21.
Also it will be understood.. 0f course, by those ^f..kl;11ed in the art that variations inthe hereinabove-described device involving the substitution' of substantial equivalents for the devices zdescribed' are intended to be comprehended within the spirit of the presentlnvention and that the invention is capable of extended application and is not coniined to the exact showing of the the drawing nor to the precise construction describednand, therefore, such changes and modi'- fications may be made therein as do not aiiect cylinder llvto be here.-A inaiter more fully described.
