3 Claims.
This invention relates to improvements in an attachment for pump jacks and refers more particularly to a pivoted link to be positioned between the upper and lower beams of a pump jack and so arranged to move the pivot of the upper beam laterally to compensate for the lateral movement of the upper end of the sucker rod where it is pivoted to the upper beam, thereby producing a straight line lift of the sucker rod or polish rod.
In the usual type of pump jack where a number of polished or sucker rods are being manipulated from a single power source through pump jacks, difiiculty is encountered in maintaining the stuffing boxes at the casinghead due to the lateral movement of the sucker rod when it is raised and lowered by the jacks.
Pump jacks have been devised, which produce a straight line lift of the sucker rod but these jacks are more expensive than the jacks which. are used. The present device oiiers a simple link mechanism which can be mounted upon the common type of pump jack and which will produce a straight line lift of the sucker rod by an arrangement which is relatively inexpensive but as efiecg5 tive as the more expensive types of pump jacks which accomplish a similar result.
Fig. 1 is a side elevational view of the device.
Fig. 2 is a view taken along the line 2--2 in Fig. 1 looking in the direction of the arrows.
Referring to the drawing, at 1 is shown the top of an oil well casing equipped with a delivery connection 2, and stufiing box 3. Through the top of the stuifing box extends the sucker or polished rod 4. Adjacent to the casing is positioned a jack which consists of horizontal frame members 5 and vertical supports 6, held in position by diagonals 7. On a pivoted bearing 8 mounted on the lower frame members is the lower beam 9. This lower beam is tilted on its pivot by means of shackel line 10. The lower beam has connection with the shackle line through members 9a and 9b which form a part of the lower beam assembly. An upper beam 11 has connection with the lower beam through a vertical member 12. The upper beam is connected to the sucker rod at a pivoted bearing 13. The tilting of the lower beam raises and lowers the upper beam which in turn reciprocates the sucker rod 4 and pumps the well.
At 14 on the vertical frame member 6 is pivoted an angled link 15; One arm of the angle link has pivoted thereon at 16 the upper beam 11. The extremity of the other arm has connection with the tilting lower beam through a member 17 in which is interposed turnbuckle 18. This con- 55 nection 17 between the angle link 15 and the lower beam is connected to the frame of the lower beam at a point adjacent to that at which the shackle line 10 is connected to the frame of the lower beam or at a pivot designated as 19.
Additional pivot points are provided on the vertical support member 6 and on the vertical arm of the angle 15, to provide for adjustment of the jack.
In operation the shackle line 10 moving horizontally tilts the lower beam on its pivot 8 ver- 5 tically moving the connection 12 between the lower and upper beam. The tilting of the lower beam moves the pivot 19 in an arc to the left and due to the connection 1'7 moves the angle link 15 on its pivot 14 so that the pivot 20 where the link 17 connects to the angle link 15 is lowered. This lowering of the pivot 20 moves the pivot 16 to the right. As the upper beam 11 is pivoted to the angle link at 16 it is moved to the right and this distance of lateral movement is adjusted to compensate for the lateral movement to the left that the sucker rod would normally have if pivoted on the vertical support 6. In other words, the sucker or polish rod is given a straight line lift and the reciprocation of the rod is in a straight line vertical direction, rather than in a slight are, as is the movement of the rod when the upper beam is pivoted directly to the support 6. The function of the turnbuckle is to shorten or lengthen the connection 17 between the arm of the angle link 15 and the lower meam to adjust the lateral movement of the pivot 16 and effect a straight line movement of the sucker rod.
The device is inexpensive, rugged, and may be applied to the common type of pump jack with little difficulty. I
I claim as my invention:
1. In a pump jack assembly, the combination including a base, an upright supported by said base, a bell crank lever pivoted on said upright, a pumping beam pivoted to said lever, a pump rod connected to said beam, a jack pivotally mounted on said base, a link connecting said jack and said beam, and means interconnecting said jack and said lever whereby the pumping beam pivot is shifted to impart a straight line reciprocation to the pump rod.
2. In a pump jack assembly, the combination including a base, an upright supported by said base, a bell crank lever pivoted on said upright, a pumping beam pivoted to said lever, a pump rod connected to said beam, a jack pivotally mounted on said base, a link connecting said jack and said beam, and a link adjustable in length pumping beam pivotally mounted on said beH crank lever, a connection between one leg of said pumping jack and said bell crank lever, a link connected to the other leg of said pumping jack and said pumping beam, and a pump rod connected to said pumping beam..
