Abstract

610,687. Chucks. ROGERS, G. V. April 15, 1946, No. 11475. [Class 83 (iii)] A chuck of the type divided transversely in a plane perpendicular to its axis into a body section 1, Fig. 1, and a detachable front plate 2 divided radially into identical sectors 6 forming between them jaw-receiving slots 4, has the sectors hardened and ground to precise dimensions. To facilitate accurate assembly, an annular rib 7 provided on the body fits a corresponding groove 8 in the sectors. As applied to a chuck with independently movable jaws, the jaw-actuating screws 21, Fig. 7, are housed in radial recesses in the body and formed with two recesses 24 to receive two sections 25, 26, Fig. 8, of a thrust bearing. Tu prevent fouling of the jaws, the front section is cut away as shown at 30. The sectors of the plate 2 clamp the two sections together in a retaining groove in the wall of the screw recess in the body. In a scroll chuck, chromium plating is applied to the scroll thread which has rounded corners to prevent chipping and to the bearing surface on which the scroll is rotated by a pinion 16.
