Abstract

287,785. Roggwiller, J. Sept. 2, 1927. No Patent granted (Sealing fee not paid). Attachments for drilling. -In a yielding-drive drill chuck the two jaws k, l, are operated by a transverse screw and are slidable in a body i rotatably mounted on the hollow base a, axial movement of the body being prevented by keys f secured to the base by screws e and engaging an annular recess in the body. Sockets h in the jaws receive plungers d pressed by springs g into a diametrical groove b<1> in a driving plate b attached to the base by a screw c. The sides of the groove are inclined to allow the plungers to ride out under excessive torque, the inclination of the sides becoming steeper from the centre towards the ends of the groove so that the limiting torque will be greater for larger drills.
