Abstract
391,295. Chucks. WARD & CO., Ltd., H. W. and WILLIAMS, W. T., Dale Road, Selly Oak, Birmingham. March 10, 1932, No. 7172. [Class 83 (iii).] In a machine-tool chuck of the kind in which gripping pieces are moved radially by means of balls, wedges, levers, &c. operated by an axially sliding member, a fluid-pressure cylinder surrounds the chuck and contains a piston connected to the sliding member. Segmental gripping pieces d are contained within a flexible sleeve c which is compressed for gripping by means of balls f operated by an annular bevelled surface g on a slidable sleeve e. A flange i on the sleeve e is moved axially in both directions by a non-rotary member h carrying a piston k slidable within a cylinder l connected by bolts to the headstock m which supports the rotary spindle b, a ball thrust bearing j being placed between the flange i and member h to take the thrust in the closing direction. The gripping pieces d are retained within the sleeve c by means of a flanged ring d<1> screwed on a bush a which is secured to the spindle b and carries the balls f. Specification 221,455, [Class 83 (iii), Metals, Cutting], is referred to.
