Abstract

165,249. B.S.A. Tools, Ltd., and Brown, W. T. April 9, 1920. Chucks.-Jaws 13 sliding in inclined guides in the body 5 are actuated by a conical scroll on the end of the shank 1 rotatable but not axially movable in the body as controlled by a race of balls 7 inserted through a hole 8 and retained by the inturned ends of a spring ring 9 seated in a groove on the body. The jaws may be circular in section and grooved to engage a pap-screw 17 or may be angular, pap-screws then being unnecessary.
