My invention relates. to vpumping jacks designed particularly for oil wells, but adapted to other apparatus.
rl`he principal object vof this invention is' to provide a pumping jack w-ith links connected between the jack frame and the pump rod so` as to provide an approximately straight line travel of the pump rod.
Referring to the accompanying drawings,
lo Fig. l is a side elevation of a portion of a pumping jack containing my invention, parts being broken away; Fig. 2, an end elevation of the upper portion of Fig. 1
` shown on an enlarged scale; Fig. 3, a side I elevation of the upper lett hand portion ot Fig. 1, the'scale being the same as in Fig. 2;
Fig. 4, yadiagrammatic view showing theposition of the links and adjacent parts when the pump rod is at its extreme posi- 2@ tions; Fig. 5a section Onthe line 5-5 on Fig. 2; Figf, a section on the line 6-6 on Fig. 2; Fig. 7, a view similar to Fig. 2, but showing a modification; Fig. 8, a side view of Fig. 7 and Fig. 9, a section on'the line 9-9 on Fig. 7.
@n the drawings, 1 designates avvertical standard or post upon which the oscillating' frame 2 is pivoted by means of the horizontal pin or shaft 3. The frame comprises the 3o upper horizontal member 4, the. vertical member 5 and the diagonal member 6 which are connected together to form a' triangular frame. The members l and 5 are jointed at a right angle ,and the pin 3 is located near this angle. The lower portion oi the member 5 has attached thereto the pull rod 7 designed to beconnected to a suitable reciprocating power device' for causing the oscillation of the frame 2 on the pin 3. l
8 designates the upper portion of a pump having the pump rodV 9. Thelend oi the member d farthest from the pin 3 is provided with a pair of bearings 10 for the trunnions 11 projecting from the sides of the upper end of the link 12. "llhe lower 'end of the link l2 has the oppositely-extending trunnions 13 which receive the upper ends of the members 14of the link 15. 16 is a swivel-block having trunnions 17 in the 5@ lower ends of the members 14. rlhe pump rod 9 extends 'upwardly through the swivelblock 16 and' is supported thereby in any suitable manner, as by the clamps 18 surrounding the pump rod, the lower clamp resting on the top of the swivel-block and .j
the upper clamp resting upon the lower one. The end of the frame supporting the link 12 is provided with an abutment 19 pendent .on the member 4 and having its outer face or edge 20 substantially at right angles with the member 4 and standing, when the member d is horizontal, substantially across an i. imaginary horizontal plane which includes the pin 3. The lower end of the link 12 adjacent to the face 2O is provided with the ou lug or stop 22 which engages the face 2G whenthe frame 2 is at or above its central or horizontal position. rFhe thichiess of .the lug 22 is such that the upper ends of the link members 1t cannot. engage the face 7@ 20, because their ends would by rocking engagement with the face 20 soon wear a hole in it and make the apparatus inecient or inoperative.
rllhe lowerends ot' the link members 14: are provided with the lugs 23 adjacent to the face 20. yilhe ends of the lugs nearest to the face 20 are connected together by the cross-bar 24: which is secured to the lugs and l u engages the face 20 when the trame 2 is eo at or above its horizontalposition, as shown on Fig. 1. The lugs 23 and the bar 24E serve as a stop carried by the link 15 prevent the swivel-block 16 from rocking engagement withthe face 20 which enga ement would soon injure or destroy the sai face.
The link 12 has in its outer or right hand face the longitudinal groove or channel 21 extending from end to end of the link to receive the pump rod 9, the groove being deep enough to allow the axial center line of the rod to lie on a line connecting the axial centers of the trunnions 11 and also in a line connecting the axial centers of the trunnions 13 when the links 12 and 15 are vertical as shown in Figs. 1- and 3. The groove allows the link 12 to move to the right away from the rod 9 as the frame member 4 moves above its horizontal position as shown in dotted lines in Fig-'4. tto
The axial center ofthe rod 9 lies also on a line connecting the centers of the trunnions 17. -When the lug 22 is in engagement with the abutment 19 as shown, the centers of the trunnions 11, 13 and 17 lie in an arc drawn from the center of the pin A horizontal line drawn from the center of the pin 3 when the arm is substantially in its central position lies between the pivots" 13 and 17 and atlright angles to the axial center of the rod 9. Thus the pivot 17 will remain substantially in verticalfalinement with the axial center of the rod as it travels during the swinging of the arm 'between its central position shown in Fig. 1 and its upper position shown at the upper part of Fig. 4. Vith the frame member 4 horizontal, the stop bar 24 rests against the abutment 19 and the centers of the trunnions 13 and 17 are in a vertical plane which includes the vaxial center of the pump rod 9. If the pump rod 9 is allowed to descend, the abut ment moves slightly to the right while the trunnions 17 move downwardly substantially vertically. After the abutment has moved downwardly for some distance and at about the time the trunnions 11 move outwardly so as to be in substantially vertical alinement with the pump.rod 9, the abutment moves slightly away from the upper ends of the link l5 so that the trunnions 13 continue downwardly substantially vertically. Also the trunnions 11 move ,downwardly in a substantially vertical plane standing in the axial center of the pump rod. Then the frame has moved to lower the pump rod to its lowest position the parts would be as shown in the lower portion of Fig. 4. Hereall of the trunnions, 11, 13, and 17 are shown one above the other in a substantially vertically plane which includes the vertical central line of the pump rod. During the downward' movement of the pump rod from its said central position, `the arc movements of the trunnions are so small as to be negligible and the lateral movements of the pump rod are so small as to permit the pump rod to move through the pump Without any added appreciable friction due to such lateral movements.
The link l2 has inits outer or right-hand face the vertical groove or channel 21 extending from end to end of the link to receive the pump-rod 9, the groove being deep enough so that when the links 12 and 15 are lboth vertical the. axial center of the rod intersects imaginary lines connecting the axial centers of the trunnions 11 and 13. The axial center line of the rod also intersects an imaginary line connecting the trunnions 17 The rod 9 is held inl a groove in the swivel-block by the cap T he groove 21 allows the link 12 to move to'the right Vaway from the rod as the frame member 4 moves above its horizontal position as shown in Fig. 4. The links 12 and 15 are in tandem and are suspended from the trunnions 11 which are parallel with the trunnions 13 and 17the trunnions all being horizontal and at right angles with the frame member 4 and parallel with the pivot pin 3.
On Figs. 7,-8, and 9 a modification is shown wherein the stop 22 of Figs. 1, 3, and 5 is replaced by the enlargement 26 on |the lower end of the link 12, this enlargement by engaging the face 20 prevents the oscillating upper end of the link members 14 from engaging with the face 20 ofthe abut- `ment 19. Thelower ends of the link members 14 have the enlargements 27 which engage the face 20 to keep the oscillating swivel-block 16 from contacting with the said face and injuring the same.
