SUCKER-ROD ELEvA'roa AND WRENCH.

Application filed August 11, 1922. Serial No. 581,220.

To all whom it may concern: I

Be it known that I, BASIL Rose, a citizen of the United States, and a resident of Louisa, in the county of Lawrence and State of Kentucky, have invented certain new and useful Improvements in Sucker-Rod Elevators and Wrenches, of which the followin is a specification.

My invention is a'sucker rod elevator and wrench, and it consists in the combinations, constructions and arrangements herein described and claimed.

An object of my invention is to provide a sucker rod elevator and wrench which will afford facilities for adjusting and elevating sucker rods in wells expeditiously, conveniently and without possibility of a sucker rod engaged by the device becoming disconnected therefrom while being elevated or adjusted A further object of my invention is to provide a device of the character described which embodies means operated automatically upon the placing of the device in position to raise a sucker rod to lock the device in engagement with the sucker rod.

A still further object of my invention is to provide a device of the character described which is relatively simple in construction, not likely to get out of order easily and thoroughly practically commercial.

()ther objects and advantages will be apparent from the following description, and the novel features of the invention will be particularly outlined in the appended claims.

My invention is illustrated in the accompanying drawings, forming a part of this application, in which;

Figure 1 is a perspective view of a sucker rod elevator and wrench embodying the invention, a handle comprised in the device being shown in the plane of the carrying block also comprised in the device,

Figure 2 is a longitudinal central section through the device, a portion thereof being broken away,

Figure 7 is a relatively enlarged fragmentary perspective of an end portion of one of the arms of the handle comprised in the device,

Figure 8 is a relatively enlarged fragmentary sectional view, the section being taken substantially along the line 8-8 of Figure 1, and I Figure 9 is a perspective view of a locking pin comprised in the device.

n carrying out my invention, I provide means adapted to releasably engage and hold the noncircular relatively reduced portion of a sucker rod or the like so that the latter may be elevated in a well and adjusted or repaired. Such means include a rod engaging member 1 having the form best seen in Figure 3 and a carrying block or member 2 by means of which the rod engaging member 1 is rotatably supported and with which the rod engaging member co-operates. The carrying block 2 preferably comprises a pair of superposed similar sections 3 and 4 respectively, each of the sections having a central bore 5 merged adjacent to one end or face of the section into a counter-bore 6. A radial slot 7 extends from one edge of each of the sections 3 and 4 through the walls of the bore 5 and the counter-bore 6, the slots 7 having straight substantially parallel side walls between which the non-circular portion of a sucker rod of ordinary construction may be moved. As stated, the sections 3 and 4 are arranged in superposed relation so that when the bores 5 thereof are in axial alinement, the slots 7 thereof are in register and the counter-bores 6 are also in register and in open communication with each other. Dowel pins 8 or like fastening means are employed to secure the sections 3 and 4 of the carrying block or member together in superposed relation as shown.

The rod engaging member 1 comprises a substantially cylindrical body 9 adapted to be received in the compartment provided by the counter-bores 6 of the connected together sections 3 and 4 and to rotate in such compartment. The body 9 has relatively reduced axially aligned substantially cylindrical portions 10 extending from the opposite ends thereof in concentric relation to the body 9 and being adapted to extend through and rotate in the bores'5 of the sections of the carryin block. A slot 11 extends radially into tie body 9 and into the aligned reduced portions 10 of the rodengaging member. The slot-ll has straight side Walls spaced apart to register with the OOIIGSPOIlCllIlg side walls of the slots 7 when the rod engaging member 1 is rotated to a certain position in respect to the carrying block 2. It of course will be understood that the sections 3 and 4 of the carrying block are not assembled and secured together until the rod engaging member 1 has been interposed therebetween and positioned in respect thereto as described.

The body 9 of the rod engagingmember has an arcuate portion of its peripheral wall cut away at 12 to provide a clearance space for a stop member 13 which extends into the compartment provided by the counter-bores 6 from a pocket defined by a complemental dove tail mortise 14 in the walls of the counter-bores 6. Spaced radially extending shoulders 15 and 16 are defined at the ends of the arcuate clearance space provided between the adjacent walls'of the cut away portion of the body 9 and the counter-bores 6. The rotation of the rod engaging member 1 within the compartment provided by the counter-bores is thus limited because'of the engagement of the stop 13 with the shoulders 15 and 16. When the rod engaging member 1 is in. the position in which illustrated in Figures 1 and 4, the slot 11 is in register with the slots 7 anda non-circular portion of sucker rod or like member may be moved through the alignedslots into engagement with the end or bottom wall of the slot 11. The carrying block 2 may then be rotated about the axis of the rod engaging member 1 until the latter is in'the position in respect thereto illustrated in Figure 5. At this time, the slot 11 is out of register with the slots 7 and the non-circular portion of the sucker rod will be held against movement from the slot 11 into the slots 7 .The carrying member 2 is fashioned to provide straight parallel edge portions 17 and 18, respectively, which are also parallel with the walls of the slots and are merged at their ends remote from the entrance to the slot 7 one into the other by a curved or arcuate portion of the carrying block. Laterally extending shoulders 19 are provided at the ends of the straight parallel portlons 18 of the edge walls of the carrying block for a purpose which .will be hereinafter set forth.

The carrying block 2 is provided with axially aligned trunnions 20 which extend therefrom at points adjacent to the shoulders 19 and at right angles to the parallel side walls of the slots 7. The trunnions 20 may be partially formed on the sections 3 and 4 as shown and are journaled in openings 21 formed through parallel end portions of divergent arms 22 comprised in a tion 23 of a handle which is generally at 24.

The handle 24 includes in addition to the parts described a shank portion 25 which is of non-circular cross sectional contour and tapers uniformly from its juncture with the yoke portion 23 to its end. The handle 24 preferably consists of two eomplemental longitudinal sections, each of which includes one of the half portions of the shank and being secured together by dowel pin 26, screws or like fastening means.

An elongated loop or ring 27 has an enlarged portion 28 at one end provided with an opening 29 therethrough which is in axial alignment with the longitudinal axis of the loop or ring. A headed pin 30 has the shank thereof extended through the opening 29 into an axially aligned socket 31 formed in the end of the shank portion 25. A washer 32 may be interposed between the head of the pin 30 and the inner wall of the enlarged portion of the loop or ring. The pin 30 may be removably held with the end portion of the shank disposed in the socket 31 through the agency of one of the dowel pins or screws 26 which is arranged to extend transversely through the end portion of the pin. The arrangement is such that the ring or loop 27 is swivelled on the shank of the handle.

esignated oke por- It is desirable that the rod engaging membox 1 shall be releasably held in the position illustrated in Figure 5 when the handle 24 is disposed at right angle to the position illustrated in Figure 1, or in other words in a position to elevate a sucker rod engaged by the member 1 in the manner described. To this end, my invention provides a locking pin 33 having a shank portion adapted to slide in a radial bore 34 formedthrough the walls of the carrying block 2 so that the inner end portion of the'shank which is rounded and which is indicated at 35, will extend into the compartment provided by the counter-bore 6 and into the slot 11 of the rod engaging member when the latter is in the position shown in Figure 5 to prevent such rotation of the rod engaging member rounded end portion of the shank of the locking pin being engaged by a side wall of the slot 11 and the locking pin moved outward by a camming action until the rod engaging member 1 is free to be rotated to the position illustrated in Flgures 1 and 4:. Obviously, spring means not shown may be provided between the head 36 ofthe locking pin and the shoulder 38 to urge the locking pin outward. \Vhen the handle 24 is in a position at right angles to that illustrated in Figure 1, the outer end of the enlarged portion of the bore 34 will be obstructed by a portion of the adjacent wall of one of the arms 22 so that the locking pin will be held against movement from looking position. However, when the handle 24 is in the position illustrated in Figure 1 in respect to the carrying block 2, the locking pin 83 may move outward since the head portion thereof may enter a recess or cavity 39 which is formed in the inner wall of the adjacent arm 22 in position to then register with the enlarged portion of the bore 37 and to be out of registration with the latter when the handle 24 is swung from the position illustrated in Figure 1 to lifting position disposed at right angles thereto.

From the foregoing description of the various parts of the device, the operation thereof will be readily understood. The device can be instantly adjusted in engagement with the non-circular portion of a sucker rod of ordinary construction when the handle is in the position in respect to the carrying block 2 illustrated in Figure 1. The carrying block 2 is then rotated about the rod engaging member 1 until in the position in respect thereto illustrated in F igure 5. The handle '24 is then swung upwardly against the radial projections 19, at which time the head of the locking pin will have been engaged by the inner side of the adjacent arm 22 of the handle and forced inwardly so that the locking pin will be in looking position as shown in Figure 5. The engaged portion of the sucker rod will then be held against accidental displacement and may be rotated or elevated in order that adjustment thereof or repairs thereto may be effected.

Obviously, my invention is susceptible of embodiment in forms other than that illustrated in the accompanying drawings and I therefore consider as my own, all modifications and adaptations thereof which fairly fall within the scope of the appended claims.
