A. WILSON ROD JOINT Filed May 19, 1925 Patented -May 29, 1928.

ROD JOINT.
Application filed May 19, 1925. Serial No. 31,2ss.
This invention relates to new. and useful improvements in rod joints.
The object of the invention is to provide a quick-detachable coupling, whereby the joint may be readily made up and quickly disconnected.
A particular object is to provide a rod coupling of the box and pin type having spaced threadpanels on the pin adapted to be inserted between spaced thread panels of the box and meshed therewith by a panel rotation of said pin.
A further object of the invention is to provide shoes on the lower end of the pin and guidesat the bottom of the well of the box,;.whereby vthe thread panels are automatically reglstered for meshing when the pin is inserted in'the box. 7
Another object of the invention'is to providea plurality of threads, whereby an adequate interlocking and axial ali'ning' of the pin and box is assured when the coupling is assembled. I
A construction designed to carry out the invention will be hereinafter described together with other features of the invention.
The'invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an exampleof the' invention is shown and, wherein: Fig. 1 is an elevation of a joint constructed in accordance with my invention.
Fig. 2 is a vertical sectional view of the same on the line 2-2 of Fig. 1, i
Fig. 3 is a vertical sectional view taken on the line 33 of Fig. 2,
Fig. 4. is an underside view of the pin, Fig. 5 is a plan view of the box, Fig. 6 is a perspective view of the lower end of the pin, I c
Fig. 7 is a transverse vertical sectional view taken on the'line 7-7 of Fig. 5,
Fig. 8 is a vertical sectional view of the or end of the box taken on the line 8-8 ig. 5, and r Fig. 9 is an elevation of the upper portion of the pin at right angles to 1g. 2.
.In the drawings the numeral 10 designates a pin member which has a screw threaded socket 11 at its upper end to receive the u per section of the pump rod (not shown). The pin'member constitutes one portion or element of the joint; while a box member 12 constitutes the. other element or portion of the o1nt. Each of the members 10 and 12 have wrench faces 13 on opposite sides and when themembers are coupled these.
faces stand in substantially the same .or parallel vertical planes; thereby indicating the coupled position.
The box has a screw threaded socket 14 A on itslower end for receiving the lower'section of the pump rod (not shown). The
member 10 has a depending tapered pin 15.
The box 12 is formed with a countersunk well 16' forreceiving said pin. The pin is formed with mutilated screw threads 17 arranged in two panels each occupying approximately one quarter of the circumference of the pin and dis osed diametrically opposite each other. This providesgaps between the panels.
The panels are formed of coarse threads, the convolutions of which are preferably spaced'sufiicientl toadmit the forming of a second thread 0 the same pitch, intermediate said convolutions. The second thread is started diametrically opposite from the first thread. Fromthe foregoing it will'be 'seen that one of the threads begins at the I lower end of one panel; while the other thread beginsat the lower end of the .dia metrically opposite panel. By thisarrangement ample thread hearing is had and a coarse. thread is available.
The well 16 is provided with double threads 18 which are mutilated. and formed I into diametrically" opposite panels having approximately the same'width as the gaps between the panels of the pin, or a little 7 clearance, so that the pinmay be easily inserted in the well 16; its threads 17 being received in the. aps of the well. The members are couplecTb rotating the pin member to-mesh the threa s. T
A very important feature of the invention is the provision of a pair of shoes or extensions 19 on the bottom of the pin. In formmg these shoes it is preferable to start the threads-17 short of the lower end of thein. To receive and support the shoes at the bottom of the well convolute seats or shoulders 20 are formed contiguous, to the threads 18. Each seat extends convolutely' under the panel inits forward path and sligllitly beyond so as to give full clearance. shoe has its advance edge or shoulder 20 so each terminating short of the advance edge of its panel thereabove, but 'this'is subject to variation.
The shoes 19 have their under surfaces or faces beveled inwardly and downwardly toward the center of the pinand the seats 20 are correspondingly beveled; however this is subject to variation. The threads 17 are spaced in such relation from-the faces of-the shoes as to readily mesh with the threads 18 when the. shoes ride down the seats -20 upon rotation of the pin member 10. It is necessary that the shoes 19 and seats 20 have such inclination'or pitch as to properly support the threads 17 for entrance between the threads 18 whenthe pin member 10 is rotated.
When the pin 15 is inserted in the well 16 of the box the shoes 19 will engage upon the seats 20 at the bottom of the gap between the panels of the threads, 18. It will be noted that the shoes and seats each have a greater radial extension or bearing surface than the threads and thus take the impact and sustainthe load which would otherwise be imposed uponthe threads. By use of the shoes and seats notonl is the load sustained, but the pin threa s are supported in position to readily mesh with the box threads without the necessity of lifting or otherwise adjusting the pin member.
The joint is tightened by a quarter turn or rotation of the pin member and this is limited by the contact of the tapered walls I of the pin 15 and the well 16, or by an interlocking of the threads due to the pitch of the shoes and seats or by the shoulder 22 at the upper end of the pin 15binding upon the upper flat edge of the box, or in any other suita lemanner. It will be noted that the thread panels 17 of the pin terminate short of the shoulder 22 which leaves an integral guide collar 23 at the upper end of the well.
The threads 18 v of the well 16 terminate short of the upper end of the well, thus leaving an annular space or socket for receiving the collar 23, which thus becomes a guide for centering the pin before it is rotated to mesh the threads.
Tests have demonstrated that the members 4 10 and 12 will not unscrew when the rod is.
rotated in a reverse direction and a wrench taper as where a continuous thread is employed.- I
I have shown the box formed with a reduced portion 24 having an annular shoulder 24 at its bottom. This :portion forms a mandrel for a guide sleeve 25 which snugly fits the same and rests upon the shoulder. lhe sleeve may extend to the shoulder 22 of the member and thus be held against rotation or it mayterminate short of said shoulder and be free to rotate. The sleeve is provided with helical guide ribs or vanes 26 on its outer surfacefor spacing the joint from the walls of the tubing. As the guide forms the subject matter of'a se arate application filed of even date herewit no claim to the said guide is herein made and the joint may be made without said guide. Y
It will be seen that when the members 10 and 12 are coupled the wrench faces 13,as before mentioned, will stand in approximately the same vertical plane. .When the pin member is 'ven a quarter turn to unmesh the threa s so that the pin' can be lifted from the box, the up er wrench face willkbe at substantially rig t angles to the lower face, thusv indicating the uncoupling position. The wrench faces may thus be used as indicators for the coupled and uncoupled positions. P Various changes in the size and shape of the different parts, as well as modifications and alterations ma be made within the scope of the appen ed claim.
What I claim is:
In ajoint for pump rods, 9. solid, in for a box, said in having longitudina thread panels on iametrically opposite sides, and shoes extending radially outward from the axis at the bottom of the pin and having incl'ined faces on theirunder sides, the threads being disposed at the fpitch of said shoes and terminatln'g short 0 the shoes.
In testimony whereof I aflix my signature.
ROBERT WILSON.
