Abstract

219,861. Rengman, T. Nov. 22, 1923. Turning; chucks.-A device for holding a drill, reamer, milling cutter, countersink, &c. for operation in a lathe comprises a casing 8 having a central aperture 3 to receive the drill &c., which is gripped by crescent-shaped jaws 2 mounted in recesses in a disc 13 rotatable in the casing by a screw 10 and a nut 5 engaging the disc, the jaws receiving an oscillatory movement through pins 9 attached to the casing and passing through slots 11. The casing is made in two parts stayed by pins 7, two of which pass through slots 12 in the disc to limit its rotation. A tommy-bar 14, inserted in an axial hole in the end of the screw 10, may be used for rotating the latter.
