<p>FIVE PIECE BRAKE LEVER CONNECTION A brake lever connection is formed from a tube with a two-piece welded to each end, each jaw having laterally spaced side portions merging at one end into end portions engaging each other to form the inner end of the jaw, which has a first frustro-conical surface tapered toward the other jaw and merging into a smaller diameter frustro-conical surface tapered less sharply. The larger end of the smaller conical surface has about the same diameter as the inside of the tube, into an end of which the smaller conical surface is inserted. The end walls of the tube form with the first conical surfaces annular recessed filled with welding metal that joins the jaws to the ends of the tube.</p> |
