Abstract

388,916. Percussive drills. ARMSTRONG, WHITWORTH, & CO. (ENGINEERS), Ltd., SIR W. G. and SWEETSER, E. H., Scotswood. Works, Newcastle-on-Tyne. Jan. 28, 1932, No. 2613. [Class 124.] The front head 3 of a percussive drill has wedgeshaped internal surfaces to receive a wedge-shaped split collar 4 surrounding the steel. Any attempt to withdraw the steel is prevented by the collet falling and becoming wedged in the lower end of the part 3 unless it is prevented by the catch 6 engaging the part 4a of the collet. The catch is maintained in its inward position by the spring- pressed plunger 9.
