Abstract

331,498. Hall, J. A. March 2, 1929. Sockets.-A socket for holding a drilling or other cutting tool is screwed on a spindle d and comprises a body a having a tapered recess m for receiving a conical shank ! on the drill c and a screw cap b provided with an elongated aperture h to receive a rectangular collar k on the drill. Internal shoulders j<1> on the cap are engaged by the collar k when the drill encounters resistance to rotation, thus serving to screw the cap on the body and secure the drill. For rotation in the opposite direction shoulders j<2>, Fig. 3, are provided on the cap, and recesses e, f are provided in the body and cap respectively to allow release of the drill by means of a tool inserted therein. The collar k mav be formed on an extension rod instead of on the drill itselt and may have a shape other than rectangular and according to the Provisional Specification the cap b may be moved axially on the body by means other than a screw thread
