Abstract

470,485. Making pipe fittings. CORNELL, E. S. Nov. 8, 1935, No. 30987. Void. Convention date, April 2. [Classes 83 (ii) and 83 (iv)] Stamping.-T and like metal (copper) fittings are made from a tubular block with thickened side 10a which forms the branch of the T. The blank with mitred ends is pressed in a split die 11 by shouldered plungers 14, 15 and oil or water 16, the plungers slightly shearing or upsetting the metal at 17 to make a fluid-tight joint, to form an initial bulge 10A. The ends are then cut square and the tube re-pressed in similar dies, Fig. 5, but with a top concave faced plug 21, to increase the bulge, after which a hole 23, Fig. 6, is punched in the dome and enlarged to full tube size by a ball 24 forced up by oil pressure and the pressure of the arcuate face 25a of a plunger 25, or by a stem screwed into the ball by which the ball is pulled through the hole. The bores of the T may then be machined to size.
