1 Claim.
1 The present invention relates to new and useful improvements in pumps of a type used for deep 'jwater wells and including power-operated means for the pump rod, and the invention has for its primary object to provide a counterbalance walking beam having its inner end connected between the power plant and the pump rod, the walking beam exerting its influence on the pump rod during the up-stroke of the latter and to thus aid in the operation of the pump.
An important object of the present invention is to provide a counterbalancing attachment for pumps of this character and by means of which the pump may be operated by considerably less power than is normally required.
A further object is to provide an apparatus of this character of simple and practical construction, which is eflicient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.
Gt-her objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure 1 is a side elevational view.
Figures 2 and 3 are vertical sectional views taken substantially on the lines 2-2 and 3-3 of Figure 1.
Figure 4 is an enlarged fragmentary side elevational view of the bearings for the walking beam.
Figure 5 is a transverse sectional View of the adjustable connection between the pump jack and the pump rod and taken substantially on a line 5-5 of Figure 1.
Figure 6 is a fragmentary sectional view taken substantially on a line 6-6 of Figure 5.
Figure 7 is a top plan View of the weight box carried by the walking beam.
Referring now to the drawings in detail, wheren for the purpose of illustration I have disclosed a preferred embodiment of the invention, the
therein and extending upwardly therefrom. A power plant I, which may be in the form of any suitable type of engine, is supported on a base 8 adjacent the pump and includes a crank, 9 connected to a pair of spaced parallel lower pump arms I 0 by means of a pivot pin I I, the upper ends of the arms being pivotally connected to the angular end I2 of the inner end of a walking beam I3 by means of a pin I4.
To the inner portion of the angular extension I2 is also attached the lower ends of a pair of upper spaced parallel arms I5 by means of a pivot pin I 6, the upper ends of the arms I5 being pivoted on trunnions I I projecting outwardly from opposite sides of a collar I8 secured in vertically adjusted position on the pump rod 6 by means of set screws I9.
The walking beam I3 is pivoted adjacent its end provided with the extension !2 by means of a bearing 20 attached to the under side of the walking beam I3 by upwardly diverging arms 2! and braced by means of a block 22 positioned between the bearing and the walking beam, as indicated in Figure 4 of the drawings.
The bearing 20 is pivotally mounted on a pin 23 extending transversely between upstanding blocks 24 secured on the upper end of an upstanding support 25 which may be in the form of a trestle, as illustrated in Figures 1 and 2 of the drawings,
As will be apparent, the walking beam is pivoted at a point to provide an inner short end and an outer long end and to the outer end of the walking beam is secured a box 26 adapted to contain suitable objects to increase the weight thereof.
In the operation of the device, the weighted end of the walking beam I 3 will exert its influence in an upward direction on the pump rod 6 during the up-stroke thereof. In this manner the weight of the pump rod will be counterbalanced by the walking beam and accordingly the pump may be operated by considerably less power than would normally be required.
The collar I8 may be adjusted vertically on the pump rod 6 to adjust the stroke of the pump.
It is believed that the details of construction and manner of use of the device will be readily understood from the foregoing without further detailed explanation.
Having thus described the invention, what I claim is:
A counterbalancing attachment for pumps of the class described and including a vertically reciprocable pump rod, a walking beam pivoted intermediate its ends to provide a relatively short inner end and a relatively long outer end, a weight carried at the outer end of the walking beam, a 4
power plant positioned beneath the inner end of the walking beam, a downwardly inclined extension on the inner end of the walking beam, 11 lower arm pivotally connecting the power plant to the lower end of said extension, an upper arm pivotally attached to the inner end of the walking beam and extending upwardly therefrom, a collar adjustably mounted on the pump rod, and means pivotally connecting the upper end of said upper arm to said collar.
