Abstract

556,760. Chucks. NATIONAL MARKING MACHINE CO., Ltd., and CUNNINGHAM, W. C. April 17, 1942, No. 5144. [Class 83 (iii)] A chuck body 1 has three pairs of lugs 24 between which are pivoted at 5 jaws 4 each having two V-serrations, the parts 6 of which, in the closed position, are parallel to the axis whilst the part 7 curves inwards. Notches 8 in the jaws are engaged by a disc 9 carried by an axially guided stem 10, a spring 13 normally moving the disc to open the jaws. The body 1 is axially movable in a back plate 20, and when moved rearwards against a spring 23 clutch jaws 21 engage and the chuck is driven. Chucking of the work and subsequent rotation of the chuck is effected by freeing the work axially by the tail stock spindle 17. The jaw parts are enclosed by a cover 14. In a modification the clutch part is omitted and the pairs of lugs 24 are replaced by a slotted annular projection.
