This invention appertains to new and useful improvements in pump jacks, and more particularly to an adjustable balance of pump jacks. t
The principal object of the invention 1s to provide a pump jack balance adapted to increase the efficiency of a pump jack thereby j uiring less power to operate the same.
re cther important objects and advantages of the invention will become apparent to the reader of the following specication and claim. t j
Figure 1 represents a fragmentary top plan view of the pump jack and balance.
Fig. 2 represents a fragmentary side elevational viewshowing the pump jack and balance. t i j Fig. 3 represents an enlarged fragmentary Vdetailed sectionalv view taken substantially on the line 3-r3 of Fig. 2.
Fig. 4 represents an enlarged fragmentary detailed` sectional view taken substantially on the line 4-4 of Fig. 2. Y
`Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 represents a frame upon which the bearings 6 are mounted to generally receivethe shaft 7 carrying the pinions 8 8, which `mesh with the gears 9--9 on in dependent stub shafts journalled in the bearings 10 on the frame 5.
The conventional power plant is generally referred to by numeral 11 and drives the shaft and pulleys 13. Each of thev gears 9 has an eccentrically mounted pin 14 projecting outwardly therefrom, and each of these pins is loosely disposed throughthe lower end of a pitman 15, the upper end of the pitmen being secured as at 16 to the horizontal bar 17 wlich in turn is secured as `at 18 to the pump ro 19.
In particularly carrying out the present invention, an elongated arm 20 is secured fxedly at one end to the outer end of one of the pins 14 and it may be necessary that this end portion of the arm be offset at approximately the point 21 to avoid any projecting elements of the pump machinery.

end of the arm 2O may be provided with a polygonal-shaped opening to receive the polygonal-shaped portion 26 of one of the p1ns14, thus preventing rotation of the arm independently of the pin.
It can thus be seen, that with the weight on the arm and the arm projecting from the gear on the .eccentric pin, the pump jack, will be, mechanically speaking, balanced, thus making it possible to operate the jack on less power than conventional jacks of thesame horsepower capacity.
While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous chang-es in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
Having thus described my invention, vwhat I claim as new is In a pump jack, a pump jack wheel, an eccentrically mounted pin on the` wheel projecting laterally therefrom, said pin being of polygonal sh'ape at its portion beyond the wheel and being journaled at its remaining portion through an opening in the wheel, the projecting portion `of the pin being engageable with the usual pump jack connecting rod, an elongated arm having a polygonal-shaped opening at one end for receiving the polygonal shaped portion of the pin, a slidable weight on the arm and means between the weight and the arm whereby the weight can be adjusted on the arm. r v
In testimony whereof I aliix my signature.
