Abstract

759,856. Chucks. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 17, 1954 [June 19, 1953], No. 17093/53. Class 83 (3). Operating - mechanism for a collet having radially-sliding jaws 6 comprises a longitudinally-movable tube 9 which carries a conically-formed cam 7 and can be moved axially by a transverse wedge 16 while the collet is rotated. The collet 6 is of the type described in Specification 735,703. The tube 9 is moved axially against the force of a spring 12 to close the collet by the wedge 16, operated by a fluid-pressure device 21. The work 23 may extend right through the tube 9 or be located in the collet by a stop 25. A swarf-protection ring 24 is fitted. A collet for gripping work internally is operated by a cone 38, Fig. 5, and may have a stepped outline for gripping workpieces of various diameters.
