Application April 21, 1937, Serial No. 138,182 . 15 Claims. This invention is broadly a connector for use in attaching a well pump polish rod to an operat ing structure, such for instance as the working beamof a deep well pump. More especially the invention is a pump rod adjuster and valve spacer. Deep well pumps commonly involve a standing valve and a working valve and it is very often necessary or desirable to change the distal rela 10 tion of the valves, and it has been proposed to accomplish this change by axial shift of the polish rod as to the operating pump beam. An object of the present invention is to provide an extremely simple, very substantial and highly 15 effective connector of this class which is char acterized by ease of adjustment to readily pro vide for the desired relational change of the spatial distance between the valves. A further object is to provide for an angular adjustment of the polish rod, and its suspended associated 2O pump parts so as to vary the working zones of contact from time to time to distribute the wear of the engaging surfaces. An additional object of the invention is to pro vide for the positive and ready angular adjust 25 ment of the rod and its pendant parts and to (Cl. 255-18) head being provided with stop latches ‘I, or other suitable means, to prevent accidental dislodg ment of the links from the body 6. Concentrically swivelled in the head or body 6 is a barrel 8 having‘ a top rim 9 seating on an anti-friction ball bearing 10 in the body; this being of generally cylindrical form. The barrel 8 has a reduced, ?at-sided portion 8a extending below the bottom of the body 6 to removably receive a transverse handle H which is held in 10 place by a nut l2 screwed onto the externally threaded end of the barrel 8. The body _6 is provided with means whereby it may be locked to the barrel 8 against relative rotation except for intentional adjustment of the 15 barrel in the body 6. As here shown the body 6 is provided with a lateral or radial pocket l3 having» transverse mouth slots l4 and opening to the body bore in which the barrel 8 is turnable. Fig. 2 shows a bolt of one type in detail as work 20 ing in and passing through a bearing ring l6 against which rests an expansion spring I‘! react ing against a shoulder of the bolt l 5a so that this is normally pressed inward and is stopped by its cross pin 15*’ engaging in slots I4 of the radial 25 pocket in which the bolt [5a is reciprocable, as later set forth. A bolt l5 of this type is opera tive in the pocket l3, Fig. 1, and its inner end interlocks in a bolt hole 811 in the rotative barrel. When the barrel is to be turnably released the bolt [5 is pulled outward so that its cross-pin I 5*) may be turned out of register with the slots I4 and then rested on the rim of the~ pocket mouth, as shown in Fig. l, with the inner end of the bolt provide for the locking of the rod adjusting means as to a main body element of the connector. Also an object of the invention is to provide a 30 highly ef?cient means to secure the attachment of the sucker rod to the connector for the loads and stresses of use in pumping. The invention consists in certain advancements in this art as set forth in the ensuing disclosure 35 \ clear of the barrel 8. 35 and having, with the above, additional objects The bore of the barrel 8 is provided with screw and advantages as hereinafter developed, and whose construction, combination and details of threads 8° and these are engaged by means pro vided to rigidly, axially hold the usual polish rod means, and the manner of operation will be made 3 to the lower end of which the pump rod string manifest in the description of the herewith illus (not shown) is connected. The rod holding 40 trative embodiment; it being understood that 40 'means includes an elongate sleeve [8 screwing into modi?cations, variations and adaptations may be resorted to within, the scope, principle and spirit of the invention as it is more directly claimed hereinbelow. Figure l is a sectional elevation of the con nector as applied to a polish rod of a pump. Fig ure 2 is a sectional detail of a locking bolt of the assembly. Figure 3 is plan of a bolt engaging ring forming a spline of the connector parts. Pump beams have divers types of links 2 for 50 attachment of the pump polish rod 3 by one form or another of connecting units. In the instant case the links 2 are engaged 45 under heavy hooks 5 projecting from opposite 55 ‘sides of a main connecting body element 6; the the threads 80 of the barrel, its ends extending beyond the barrel. The rod 3 slidably ?ts in the bore of the sleeve l8 and means are provided to securely clamp the rod 3 at the desired place in 45 the sleeve. The clamp device includes duplicate chuck thimbles 20 each having a cylindrical bore and being threaded at 23 on the ends of the sleeve 18. Slidably mounted in each thimble 2B is a pair of cylindrical bushings 2| each conically bored complementally to and receiving a chuck skein 24 having endwise converging portions fitting in the respective bushings 2| and being longitudi nally slotted inwardly from each end. When 55 2 2,114,090 the thimble 20 is screwed well onto the near end of the sleeve N3 the ends of the pair of bushings 2 I, therein, will abut, one against the. near end of the sleeve I 8 and the other against an internal shoulder 20a in the thimble 20 with the result that the slotted skein will be positively contracted, ceive and hold the rod, a barrel in which the sleeve is turnably threaded, a body in which the barrel is turnably supported, and means inter locking the sleeve and the barrel to the body against rotation. 5 by the bushings 2|, onto and clamp the polish which said means provides for releasing either rod 3 so that it is carried by the screw sleeve l8 and may be raised or lowered, or rotated there the barrel or the sleeve for relative rotation as to 10 by at will. The slots 22 of the skein extend past each other to give desired ?exure. Means are provided to positively rotatively in terlock the rod carrying screw sleeve I8 to the main body 6 to insure the feeding of the screw 15 sleeve up, or down, to raise or lower the rod 3 as desired. This means includes the spring-set latch bolt 158*, Fig. 2, mounted in the upper end of the body 6, and whose inner end engages in one or another of notches 26 provided in the rim of 20 a dog-ring 21 which is sunk in the top end of the body 6 and retained between the upper end of the barrel 8 and a flush plate 28 fastened in the top of the body 6, as by screws 29. The dog ring 21 surrounds the sleeve loosely and has an 25 internal dog or spline 21*‘, Fig. 3, slidably ?tting in a longitudinal key-way [8a in the sleeve l8. If it is desired to angularly adjust, or turn, the polish rod 3 and its suspended pump parts in a well it is only necessary to draw the bolt l5 30. from looking engagement with the barrel 8, in bolt hole 8*’, and turn the bolt IE to carry its cross-pin l5b away from its pocket slot M, Fig. 1, so that the bolt may rest in open position. At the same time the upper bolt l5a is similarly 35 drawn to release the dog-ring 2'! and turned to open-rest position. It is now possible to turn the lever II and by it the threaded barrel 8 and the friction of the rod loaded sleeve l8 on the threads 8° of the barrel will cause the sleeve 18, with the sucker rod ‘string, to be turned with and by the rotated barrel 8. Therefore, the rod and its attached pump parts will have been angular ly shifted on or as to bearing surfaces engaged thereby. Following this adjustment the bolts 45. l5—-—l5a are tripped to spring into normal look ing relation with parts 8 and 21, respectively to prevent undesired rotation of the rod clamping sleeve as to the connector body 6. To effect a longitudinal shift of the sleeve I8 50 without releasing the rod 3 in the chucks v2f] it is only necessary to draw the bolt l5 and turn it to open rest position of its pin l5b, thus unlocking the barrel 8. The barrel is now rotated by the hand lever II while the dog-ring 21 is still bolted 55 at 15a to the body 6 with the result that the threads 8% react to raise or to lower sleeve 18, ac cording to the direction of rotation. When the desired axial shift of the rod 3 is completed by action of the barrel on the screw 60 sleeve, the bolt I5a is again tripped to engage and lock the dog-ring 27 to the body '6. Angular adjustment or longitudinal shift of the sleeve [8 and its clamped rod 3 may be ac complished at will without it ‘being necessary to 65 stop the pump action or break down the con nector in any way. The operation of the lever I l is preferably timed on the down stroke of the pump rod apparatus, that is, following the lifting or load stroke since the friction of the threads 70 of the sleeve I8 is then much reduced below the lifiting friction.
