To all whom it may-concern;

Be it known that, we, Planer C.

The metal is Couplings; and we do declare the 'followin caused 'to fill the countersunk portion at the inner end of'the sleeve by the upsetting tool which flattens, the metal-in the countersunk part and at the same time a fillet 5 is formed thus giving the sleeve and red at suitable finish 'at this point: As the heated nu't'al contracts longitudinally the squared eveled portions of'the rod are drawn imvardlwwith tremendous force, bringing the sleeve and rod into a 'union nearly as close as if the parts were integral. The protruding?en- ,larged end of the rod is threaded, as at 6. Two opposite sides of the sleeve are flattened, as at 7, to afford parallel surfaces to be engaged b'v a suitable wrench. S is a be; the axial bore of which is'threaded invention, such as will enable otli'ers skilled in the art ,to which it. appertains to nialre 'and use the sanie, reference being bad to the accompanyingdrawings, .and',to the letters and figures 'of reference inarked thereon, which form a part of this specification.
