TO ALL WHOM IT MAY CONGEBQN Be it known that we,l ADAM GOOD, J'r., and SIMON STBOUSE, both of Titusville, inthe county of Crawford, and State of Pennsylvania, have invented certain new and useful Improvements in Sucker-Rod Joints for Oil- Wells, Ste., of which the following is e full, clcar, and exact description, reference being had tothe accom punying drawings, which make part of this specification, and in whichl Figure l represents a. longitudinal section of' our improved sucker-rod join Figure 2 a transverse section of the same, at the line :c :n of fig. 1, Figure 3' a similar section, at theline yy of fig. 1,.' Figure 4 a similar section, at the line z' .e of' fig.-1, and

Figure a longitudinal section, showing a modification of' our invention, in which the bolts are dispensed with'. lhe object of ,our invention is to provides. simple end efficicnt connection'or joinhf'or lthe sucker-rods of oil-wells, 85e., which shall firmly unite the sections of the "rod, without risk ,of becoming disconnected, or of -lo'sing the' tools in the well, by which accident great expenseis entailed, and the abandonment of the well sometimes necessitated; to which .end our improvement consists in inserting fiat metallic tongue-pieces, in longitudinal slots, in the ends of the sections to be united, said;tongue-pieces'being held in the wood by transverse projections formed upon them, and clamped therein by'a tube, which embraces the end of the section, which tube is made tapering inside, so as to drawthe wood-"together, and hold the tongue-piece firmly therein. The ltube and tongue-'piece urp connected by means of' abolt, which bears against a eollarfon the inside ofthe tube, and screws into a. nut, formed upon the outer end of the tongue-piece, so as to draw the tube further upon the wood, in case of shrinkage, Ste., and the tubes are connected with each other by :bullion-coupling', having a male screw upon cach end, which screws into athrcadcut upon the inside of the tube. t

In the accompanying drawings, which show a convenient arrangement of part Afor'carrying out the objects of our-invention, E represents a portion of one of the sections of a sucker-rod, and C ametallie tongue-piece,4 .inserted in a longitudinal -'slet in its end. The tongue-piece C is held inthe wood 'by means of the transverse projections c, formed upon it.. The outer end of the tongue-piecois enlarged and formed into a nut, C. A tube, made tapering on its inside,isl driven over the section E, which is made similarly tapering towards its end, by whih means the wood'iseompresscd upon the tongue-piece C, and holds it firmly in position. A collar, b, is formed upon' the inside of the tube B, through which nl bolt, D, passes, and beurs against it by means i sfits collnrd. The bolt D screws into the nut C of the tongue-piece, and connects toirmly with the tube di, which can be drawn up further on the section E, when desired, by means of the bolt D and nut C. Byv this means, should the tongue-piece become slack in the section by shrinks-ge of" the wood, it can be readily i tightened. l i 1'- 1 y A i -Y The tubes are connected by the uhion-eoupling A, thc centralpart of which is formed of square or other convenient polygonal cross-section, so as to be turned by a wrench, und having male screws a upon its ends, bywhichit connects with the tubes which are to be united. Fig. 5 shows a modification of our invention, in which the tongue-piece C screws into the tube B, and the tongue-pieces are secured together directly, without the iiitern'reilatiou of thc'nion-'coupliug A. -The projections in this case are made square, instead of curved.

Our invention provides nstrong, safe, and simple joint, and without dangerously wealiening the ends of thesectiongzis is done in many joints in common use.. It is, moreover, applicable to the drilling-poles of oil, salt, or :xrtcsinu wells, insuring the operator against risk of disconnection, onlosiug tools in the well, which, iu such eases, would be very disastrous. In somo joints in common use, rivets `are employed, which become loose and drop out, und, falling in to the pump, injure it to such an extent that tho tubing and pump mustbc drawn out of' the well at great expense. p

Haring thus fully described ourl invention, what we `claim therein as new, and desire to secure by Letters Patent, is-- Y Y i t 4 -As'eombined with the union-joint A, the socketed connection, consisting ofthe tapering tube B, the tongue C, w-itli'h-its enlargements, and the adjusting-screw D, all substantiallyas shown and described.
