Abstract

12,270. Hill, J. W. May 29. Coupling-links; shackles.-The link is made in halves A', A', Figs. 3 and 4, which have abutting heads a<1>, a<2>, a<3>, a<4>. The halves are held together by a box-like part consisting of the halves B<1>, B<2>, suitably recessed to fit the heads a', a<2>, a<3>, a<4> and the reduced sides l of the link halves. The parts B', B<2> are secured by the screw D or by a stud rivet or the like. The head d' of the screw fits into the recess n on the part B<2>. The lead washer o placed on the square part d<2> of the screw engages channels p in the sides of the hole f<1> in the part B' to lock the screw. The screw may be locked by other means. For small links, the pin q, Fig. 1, is preferably stamped in one piece with the part B<2> and is riveted on the outside of the part B<1>. The parts A<1>, A<2>, B', B<2> are preferably made as steel stampings.
