PUMP JACK;
Application filed August 14, 1919.
To all whom it may concern.
Be it known that I, ERNST A. H. JACOB, a citizen of the Republic; of Germany, residing at San Antonio, in the county of Bexar and State of Texas, have invented a new and useful Pump Jack, of which the following is a specification.
This invention relates to improvements in pump acks, and more particularly to the gearing construction, used in connection therewith.
The primary object of the invention, is to provide a pump jack having gearing con structed to convert rotary motion into reciprocating motion, thereby eliminating the usual jerks, and vibrations prevalent, during the operation of the pump jacks, now in use, and in which cranks and levers form a part of the operating mechanism.
A further object of the invention is to provide a pump jack having means for imparting a continuous, uninterrupted movement to the movable elements of the jack, thereby eliminating undue wear directed to the sucker rod.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed without departing from the spirit of the invent-ion.
Referring to the drawings Figure 1 illustrates a side elevational view of a pump jack constructed in accordance with the present invention.
Figure 2 illustrates a vertical view taken through, the pump jack.
Figure 3 illustrates a sectional view taken on line 33 of Figure 1.
Figure 4: illustrates a sectional view taken on line H of Figure 2.
Figure 5 illustrates a. sectional view taken on line 5-5 of Figure 2.
Figure 6 illustrates a sectional view taken on line 6-6 of Figure 8.
Having reference to the drawings in detail, the support includes the base 5, and upwardly extending side bars 6, formed of suitable material and having their lower ends connected to the base 5 as at 7, the upper ends thereof, having connection with Specification of Letters Eatent.

Serial No. 317,522.
the horizontally extending angle bars 8 and 9, as at 10, the opposite ends of said hori- Zontally extending angle bars 8 and 9 hav ing connection vwith the vertical side bars 11 of the pump jack frame, which have their lower ends terminating at points adjacent the base 5, and connected thereto, as by an 'le irons 9.
fiisposed on the inner surfaces of the side bars 11, and extending longitudinally there of, are the guide ways 18, the same being secured to the side bars 11 by means of the bolt-s '14, passing through suitable registering openings, formed in the side bars 11. and guide ways 13. I
The pump ack, operating within the frame, includes the heads 14 and 15, each of which being provided with an inner curved wall 15, and as shown, said heads are supported in spaced relation with each other, by means of the guide bars 16, and 17, which have their ends connected to the side edges of the respective heads 14 and 15', as at 18.
The rack bar, forming an important feature of the present invention, includes vertically extending side bars 19, disposed on opposite sides of the heads 14 and 15, and have connection with the central port-ions thereof as at 20 and 21, thus dividing the space between the guide bars 16 and 17, into runways, for purposes to be hereinafter more fully described.
A boxing 22, has connection with one of the ends of the side bars 19, as at 28, which boxing, is apertured to receive the upper extremity of the pump rod, 24, which pump rod, as shown by Figure 4 of the drawings,
has a threaded portion 2 1 which cooperates with the nuts 25 for securing the pump rod against displacement with relation to the boxing 22.
Between the side bars 19, are the horizontally disposed fingers, or bars 25, arranged throughout, substanitally the entire lengths of the side bars 19, in spaced relation with each other, to provide a rack, which is adapted to cooperate with the pinion 26, keyed to one end of the shaft 27, which shaft 27 operates in the bearing 28 and has connection with the relatively large gear wheel 28', also keyed to the shaft 27. Extending into the runways, are the lugs 5, which contact with the bracket 29, for restricting lateral movement of the pinion 26 within the run way.
The bearing 28, is provided with a depending bracket 29, terminating in a collar 30, which collar is mounted to oscillate on the horizontally disposed stationary shaft 31, suitably supported on the frame, and on which shaft is fitted, the relatively small gear wheel 32, meshing with the relatively large gear wheel 28, for transmitting motion thereto.
As shown, the relatively small gear wheel 32, is provided with a substantially long hub section 33, extending laterally and having connection with the hub of the belt pulley 34, which is keyed to the hub section 33, whereby movement of the belt pulley 34:, transmits rotary movement to the gear wheel 32.
Disposed adjacent the belt pulley 34 is the belt pulley 35, of a diameter equal to the diameter of the belt pulley 34, which belt pulley, 35 is mounted to revolve freely on the power shaft 31 whereby a power belt not shown, and which has connection with a suit-- able power generating element, runs nor mally idle on the belt pulley 35, until it becomes necessary to cause the operation of the pump jack, whereupon said power belt, is shifted, that is after the same has attained a predetermined speed, to the power pulley 34:, with the result that the rack bar moves vertically within the guide ways.
It follows that the sucker rod, which has connection with the lowerend of the rack bar is moved steadily and freely within the well casing, not shown.
In operation,'rotary motion of the power shaft is transmitted to the pinion 26, through the gear wheels 28, 32, and shaft 2'7, with the result that the rotary movement of said pinion 26, which has connection with the bars 19, causes the pump jack proper to move the limit of its vertical stroke in one direction, whereupon the pinion 26 contacts with the inner curved wall of the head which is now adjacent the pinion 26, causing the pinion 26 to move laterally, or oscillate on the shaft 29, into the run-way on the opposite side of the rack bar, with the result that the jack proper is moved to the limit of its stroke, in the opposite direction.
Having thus described the invention, what is claimed is In a pump jack, a frame, guideways sup ported by the frame, a pump jackingincluding guide bars movable within the guideways, heads connecting opposite ends of the c i guide bars, each of the heads having a curved inner surface, side bars having connection with the heads at points intermediate the ends thereof, horizontal bars connecting the sidebars, a pinion adapted to move between the horizontal bars and guide bars, an arm supporting the pinion, means for rotating the pinion, and said pinion adapted to contact with the curved surfaces of the head to move the pinion to opposite sides of the horizontal bars In testimony that I claim the foregoing as my own, I have hereto afiiXed my signature.
