Abstract

329,269. Thomas, C. S. Dec. 12, 1928. Hand and breast drills; sockets.-A drill formed to engage the spindle of a brace &c. in the manner shown is prevented from disengagement by a sliding sleeve 3 shaped to fit the two parts and counterbored at 3<c> to receive a spring confined within an outer sleeve secured at 5a to the handle spindle. Pins or projections 3<e> on the sleeve 3 engage slots in the outer sleeve to limit relative motion and transmit torque. The spring maintains the parts in driving relation but permits the sleeve 3 to be pressed back for removal of the drill.
