Abstract

165,956. Brown, W. T. April 8, 1920. Chucks.-In drill-chucks adjusted by screwed sleeves, balls or other antifriction members engage corresponding helical grooves in the screw members, stops being provided to limit relative movement between the parts. In the drill-chuck shown in Fig. 2, balls 18 are placed in corresponding grooves 5 in the central part 1 and rotary outer parts 4, 11, and the balls are confined by pins 19. The rotary outer part is formed of concentric portions 4, 11 and a cover 8 secured together by screws 12 &c., and the gripping jaws 10 are placed in radial slots in the end of the part 4 and engage the flat end of the part 1 and the internally coned end of the part 11. The jaws are opened by a spring 16 threaded through eyes in them.
