Abstract
720,368. Angular bending. DUNLOP RUBBER CO., Ltd. July 11, 1952 [July 20, 1951], No. 17221/51. Class 83 (4). In apparatus for the production of shaped loops of wire for cycle tyre beads an intermittently rotated former carries clamping and shearing means operated during a dwell between rotations. The former comprises a back plate 26 with pivoted sectors 28, 29 linked to a radially adjusted sector 27. The former is mounted on a shaft 39 rotated with harmonic motion by a slider crank mechanism, Fig. 4 (not shown). The former is held stationary between rotations by a spring-urged locking pin. A cam 37 operating the clamp 35 and a plural cam 38 operating the shearing mechanism 36 are mounted on a shaft 39. The cam 38 lifts a rod 74 to raise a pivoted blade 71 co-operating with a block 70 in position to shear the wire and lifts a shear operating rod 75. An edge cam 68 operates the rod 75 to effect shearing. The cam 38 also raises a rod 79 after shearing to lift a gripper 72 vertically and to swing it clear of the wire to allow the forward loop to be removed. A push-rod 82 is then operated by cam 37 to project a bolt under the loose end of the wire to position it under the clamp. In order to compensate for slight shortening of the wire after shearing the free end of the wire is deflected over a projection 34 on the back plate 26 by displacement of a guide 25 with spring jaws. The free end of the wire is fed through guide 25 and is clamped by the clamp 35. The former is then rotated and a loop is formed. At the dwell period cam 38 lifts and swings the blade 71 to effect shear and clamp 35 is released by push-rod 79. The loop is removed and bolt 83 through cam 37 positions the stock for clamping. Specifications 720,367, 720,369 and 720,370 are referred to.
