Abstract

645,529. Chucks ; mandrels. MINISTER OF SUPPLY. Nov. 29, 1948, No. 30977. [Class 83 (iii)] A chuck comprises a plurality of semicircular jaws 9 which are moved to grip a workpiece 15 by means of members 5 provided with teeth 6 engaging teeth 10 on the jaws, the members 5 being moved radially by means of a scroll 1 rotated by means of a bevel pinion 2 engaging teeth 3 thereon. The jaws are mounted in guides 8 formed in the chuck body and are supported for part of their length in recesses 16 in a mandrel 17, the latter being formed with a centre 19 to receive the tailstock point in cases where the workpiece has an axial opening. In a modification, the scroll and members 5 are replaced by pinions each engaging one of the jaws.
