Abstract

808,787. Chucks. BURNERD & CO. Ltd., F. Aug. 15, 1957 [Nov. 9, 1956], No. 34308/56. Class 83 (3). An adjustable work-stop, for a hollow spindle chuck, comprises a disc 1 having at least three spring-urged balls 5 in equally spaced radial holes 4, and a central screwed hole engaged by a screwed stop 8, having a rounded head 9. The stop 8 is lockable by a radial screw in the disc or, alternatively, by a nut 11. The disc slidably fits an axial bore 2, and abuts a shoulder 7 of the chuck 3, and is held by the balls 5 engaging an annular recess 6 in the chuck, the width of which is less than the thickness of the disc to facilitate removal. The disc may be replaced by an extended cylinder having two diametrically disposed spring-urged balls. Specification 735,703 is referred to.
