Abstract
809,515. Chucks. WARSITZ, E., [trading as MASCHINENFABRIK H. E. WARSITZ]. April 18, 1956, No. 11830/56. Class 83 (3). A chuck wherein the jaws 3 are adjustable jointly or individually, comprises screwthreaded spindles 5 rotatable individually for adjusting the jaws separately, and jointly moved radially by rotating nuts 13 on the spindles to effect adjustment of all jaws simultaneously, the nuts being rotatable through irreversible gearing 21, and the spindles being mounted in the jaws or jaw-carriers 2. The heads 4 of the screws 5 are retained in the jawcarriers 2 by ball-bearings 6 and, for adjustment of the jaws jointly, are prevented from rotating by the engagement in serrations 7 in the heads of serrated-plates 8 operated by screws 10 in the carriers. The screws 5 are then moved radially by rotating the nuts 13, which are formed as worm-wheels engaged by worms 21 interconnected by bevel-wheels 22 and rotated by a key-recess 23 in a sleeve 24 on one of the worm-shafts. Ball-bearings 16, 18 locate the nuts between lower seatings 15 and upper seatings 17 screw-threaded into bores 14 in the body 1 of the chuck. The appropriate locking- plate 8 is freed to allow rotation of the corresponding screw by its key-recess 12, for adjusting a particular jaw independently of the other jaws. The jaws may be integral with the carriers or secured thereto by screws.
