Abstract
588,515. Chucks. NEILL & CO. (SHEFFIELD), Ltd., J., and BURGON, F. H. Feb. 26, 1945, No. 4728. [Class 83 (iii)] In a bevel-closing chuck rotation of an external sleeve causes the gripping-jaws to move radially. The jaws 10 are slidably mounted in inclined guides formed by slots in a truncated carrier 12 and are retained by a tapered surrounding housing 13 secured to the carrier by setscrews. The jaw assembly is slidably located within a recessed body 20 integral with a shank, a hardened steel ring 22 seated at the bottom of the recess forming a stop plate to the ends of the jaws, contact being maintained by a spring 16 in a recess in each jaw acting against anchor pins 19 in the housing 13. A spring 26 urges the carrier away from the ring 22 and against the lip of an external sleeve 24 which engages a shoulder on the housing, the sleeve being threaded over the body 20. Rotation of the sleeve moves the carrier into the recess, the jaws being constrained to move radially inwards by the ring 22. On reversing the sleeve, the spring 26 pushes the carrier out of the recess, and under the influence of springs 16 pushing the jaws against the ring 22, the jaws are opened. The pins 19 may be replaced by a dished washer.
