OPERATING HEAD FOR PUMPS AND LIKE.
Application filed April 29, 1925. Serial No. 26,684.
This invention relates to an operating head for transmitting reciprocating motion from a source of power to a driven element through a walking beam. The present invention is disclosed as applied to a pump operating head for transmitting motion to the sucker rods of a reciprocating pump. Due to the arc of travel of any fixed point on a walking beam, rods directly connected thereto will be sprung laterally back and forth at each stroke.
tionable in a short stroke pump as a long stroke pump because of the shorter lateral movement. The present invention has for its primary object the provision oi a hanger structure whereby a pump polish rod connected to the walkinggbeam will have the pull of the latter continuously transmitted thereto in a straight line. Another object of this invention is to provide a structure which will cause the rods and pump piston to be turned. The objects together with other objects and corresponding accomplishments are obtained by means of the embodiment of our invention illustrated in the accompanying drawing. in which:
Fig. 1 is a side elevation showing a fragment of a walking beam and a polish rod with my improved hanger secured thereto; Fig. 2 is an enlarged View in section of the hanger; Fig. 3 is a section as seen on the line 33 of Fig. 2; and Fig. 4 is a section as seen on the line 41 of Fig. 1. Figure 5 is a section as seen on line 5-5 of Fin. 2.
Referring more particularly to the draw ing, 5 indicates a Sampson post upon the top of which is mounted in the usual manner a. walking beam 6. The end of the walking beam is bifurcated to provide legs 7. Secured t0 the walking beam at the end thereof is a frame consisting of side plates 8 carrying rails 9 of suitable curved form and disposed belowslots 10 in the plate. The rails 9 are of channel form.
Riding on the rails is a carriage comprising; an axle 11 having" stub shafts 12 upon which are journalled wheels 13. The axle 11 is underslung and is provided at the center with an opening and bearing; for a s eeve 14: having intermediate its ends a ratchet wheel 15 with laterally extending teeth. The lower end of the sleeve is suitably threaded to receive nuts for holding the sleeve in position upon the axle, The up- This is not as objec-.
per end of the sleeve is likewise threaded to receive nuts. Journalled upon the sleeve 14- is a collar 16 disposed at one end 01 an arm 17. At the other end of the arm 17 are a series of apertures adapted to receive a pin 18 which may be disposed in a selected hole. Bridging the plates 8 is a rod 19 arranged to be engaged by the pin 18. The carriage is arranged to roll back and forth along the rails, and at the end of the inward travel. pin 18 engages rod 19. Extending radially of the collar 16 is an arm 20 having a ratchet pawl 21 at the end thereof en-' gaging the teeth on wheel 15. Thus, move ment of the arm 17 in one direction will cause the pawl to engage the ratchet wheel and turn the latter. to the arm 17 in such a manner as to tend to cause the pawl to be advanced. Engagement of pin 18 with rod 19 causes the pawl to be retracted. Extending from the axle 11 is an arm 23 having pivotallv mounted thereon a pawl 2 1 engaging the ratchet wheel. This pawl is arranged to prevent retrograde movement of the ratchet wheel. A square sleeve 25 s idably extends through a square opening; in sleeve 14. The upper end thereof is provided with a head 26. and interposed between the head and the axle is a compression spring" 27. Extending through the sleeve is a sucker .rod' 2S'having a head 29. the head 29 will arrest any downwardmovement of suckerrod 28 and permit adjust ably positioning the latter and holding it in place by a set screw 30. An upward pull upon the axle will cause the sucker rod to be moved upwardly. The weight of the polish rod sucker rod, and attached parts will cause the latter to move downwardlyby gravity and maintain it in position upon the carriage. The carriage rolls backwardly and forwardly upon the rails, and to pre vent the axle from becoming disaligned,
. At the end of each inward oscillation of the carriage, the pawl arm 17 isarrested by the pin 18 striking rod 19 There is EtCllSlHOlling action due to spring 22. The energy stored in the springaids in starting the car- 'ria e rollin in the 0 osite direction,
Each complete oscillation of the carriage causes the pawl and '"ratchet to turn the polish'rod and connected parts, thereby rotating thepiston withinthe pump, which is advantageous in producing even wear.
