Abstract

693,691. Making cycle-frame lugs. PHILLIPS & CO., Ltd., J. A. April 24, 1951 [May 2, 1950], No. 10761/50. Classes 83 (ii) and 83 (iv). Stamping.-Cycle - frame lugs are pressed from a flat blank in a series of shaping operations to form an inclined dome-like boss 23, Fig. 14, which is slotted longitudinally at 33 and formed to an open-ended socket 35, Fig. 17. The boss 23 is pressed in successive stages by cup-shaped press-tools which successively increase the angle of inclination of the boss and after slotting, the socket 35 with lugs 34 is formed by forcing a plunger through the slotted end. The wings 24 of the blank are cut away at 29, bent to cylindrical shape, and welded or brazed together. In a modification the wings 24, Fig. 21, are pressed to form ears 45 with apertures 49 for a clamping bolt used to secure a tube within the lug.
