STICKER-ROD JOINT.
Application filed March 13, 1920. Serial No. 365,454.
To all whom it may concern: i Be it known that I, GUS ADAMS, a'citizen of the United States, residing at Br ea, in the county of Orange and State of California, have invented a new and useful. Sucker-Rod Joint, of which the following is a specification. 1 The invention relates to joints for sucker rods and the like and is more particularly directed to that type of joint most generally employed for connecting together sections of oil-well sucker rods. I
An object of the invention is to provide a joint for sucker-rods and llllB lllIG in which the cooperating'rod ends are'of duplicate size and contour. j Another object is to provide a joint having no screw threads. I 1
Another object of the invention is to pro vide a joint of the above character adaptable for speedy manipulation.
,A further object is to provide a joint of great-strength and simplicity, and suscepti' ble of convenient operation. I
Another object is toprovide a joint having means for securing the sections togetherby direct transverse clampingtension.
' Another object is to provide a joint having a split clamping member combined'with means for expanding said member in conv necting and disconnecting the-joint.
Another object is to provide a joint in which the two cooperating rod ends are of duplicate size and contour.
Va-r1ous other objects andadvantages will be more fully'a parent from the following description of t e accompanying drawings which form part of this disclosure, and
which illustrate a' preferred form of embodiment of the invention.
Of the drawings: v a Fig. 1 is an elevation of the upper end of a rod' section which will herein be referred to as the lower section.
a rod section which is to be connected to the section in the well, the clamping member and the cooperating expanding device.
Fig. 3 is a top plan view of the parts shown in Fig. 2.
Fig. 4 is an elevation of the rod shown in i Fig. 1 looking at the face of the serrated surface.
Fig. 5 is a side elevation of the split sleeve member showing the longitudinal split theres member "shown in section;
rod sections" ot-a'modified form.
panding*'jaws indicated in dotted line's. v F ig. 6 is an elevation of two sucker rod sections joined together, with the clamping Fig. 7 is a sectiorron line zfl-w of Fig. 6'; I
in, withthe expanded position' of the ex- Fig.8 isafvieiw similar to Fig. 6 showing into the well. 'Each section has an enlarged end transversely out to provide coincidently I contoured inclined c'ooperatingsurfaces 3 having teeth orfserrations adaptedto inter, mesh when the rod ends are brought together. It will .be' noted that theserrations 'or teeth of both rods are dentlcal thereby permitting them to be formedor machined with the same dies or machine tools. This is'an important item in the pro- 'duction cost of these rod sections: an'dit is 0t further importance in this regard that'jthe sections have'no screw threads.
With reference to Figs. 6 and "7 which 1 show the two sections 'connectedflle designates a clamp sleeve. This sleeve, whichv shown in detail in. Fig. 5, is [splitlongitud nally as] indicated 'atf5, and is of a, normal internal die f ameter'which is slightly less thanthe external diameter of-the cooperating enlar ed ends of therod sectiona The walls of'the sleeve are of; a suitablenthickn'ess and the' sleeve is formed of snitable'materiah to provide a relatively powerful inherent,eon-
tractible tension normally tendingto contract the sleeve to its normal dlameten To pp y the sleevewtothe v rod d it must first .bej'expanded then placed in position as in Fig. 6, andthen the'expanding means :must be disengaged to allow the inherent contractible tensionof the sleeve to act Fig. 2 is an elevation of the lower end of Fig. j upper rod section will then be properly intermeshed with the lower rod section, after which the sleeve will be again expanded, slipped in place and then released to clamp the sections together.
As shown in Fig. 5, the opposed edges of the sleeve wall, adjacent the split 5, are beveled to provide f-shaped throats 7 into which the expanding device engages to expand the sleeve.
The expanding device shown comprises a housing formed of two plates 8, 9 fixed together and maintained in spaced relation by three shoulder-studs 12, 12, 13, the plate 8 having a semi-circular forward end 10 providing a sleeve receiving channel and having inturned edges 11, 11 retaining the sleeve therein. The plate 8 extends rearwardly, terminating with a handle 14, and the entire housing may be swung on a chain 15 if desired.
A rock shaft 16 is journaled in the plates 8, 9 and is provided with an external operating lever 17 and a double operating; cam 18 between the plates.
Opposed expanding jaws 20, 20 are positioned between the plates 8, 9 and are re spectively journaled on the studs 1* 12. Each jaw has a forwardly extended wedgeshaped nose 2'1 which will be in alignment with the adjacent ll-shaped throat 7 of a sleeve when said sleeve is positioned within the sleeve receiving channel ofthe plate 8, (indicated in dot-ted lines in Fig. 5), and a rearwardly extended arm 22 adapted to be engaged by the cam 18. Springs 23, 23 attached to the awe and engaging transverse pins 24, 24 tend to maintain the arms 22, L2 of the jaws in contact with the operating cam 18.
With the parts positioned as shown in Fig. 2, it will be evident that if the operating lever is turned the jaws 20, 20 will close, their wedge-shaped noses 21 entering the V shaped throats 7, 7, of the sleeve 4a to expand the sleeve to a diameter which will allow said sleeve to slide freely over the enlarged rod -ends.
In Fig. 8, I have shown the rod ends pro vided with shoulders which will tend to prevent longitudinal displacement of the clamp ing. sleeve by accident or otherwise.
The above structure provides a rod joint which has no screw threads and in which the rod ends are clamped together by direct transverse clamping tension ofv an inherently contractile clamp member. The ends of the severalrod sections being of duplicate size and contour, further enhances the value of the device both from a standpoint of simplicity of structure as well as cost of manufacture and convenience and speed of manipulation.
It will be evident that the exterior surfaces of the rod ends or the interior surface of the clamp member, or both, may be ronghe'ned or transversely corrugated to guard against longitudinal slippage of the parts, without departing from the broad scope of the present invention, and also that various different types of expanding means may be employ ed. I
Of course while I have described the joint herein shown as a sucker-rod joint it is to be understood that it is not confined to such specific use as it is equally as well adapted for other uses as it is for use on oil well SULlZQY-lOClS.
