Abstract

567,324. Chucks. ARON, E., and VIDAL, C. H. July 2, 1943, No. 10811. [Class 83 (iii)] Chucks with radially moving jaws, particularly self-centering chucks, have the operating key arranged to engage parts of the mechanism with different mechanical advantage to provide for a rapid adjusting movement and a powerful tightening movement. Jaws 10 are guided by ribs 13 in radial slots 11 and are formed with arcuate teeth to engage worms 15 combined with pinions 16 meshing with a common crown wheel 20. The pinions 16 are pinned at 18 on spindles 17 formed with squared recesses 19 for a key. Also meshing with the wheel are a number of pinion shafts 25, the pinions 24 having a less number of teeth than the pinions 16. Squared recesses 27 are provided for the key. When the key engages any of the recesses 19, the jaws are moved more rapidly than when a recess 27 is engaged. In a modification, the pinion shafts 25 are replaced by recesses to receive a pinion key directly engaging the wheel 20 and the recesses 19 are formed with internal teeth to engage the pinion key.
