Abstract

166,614. Collier, W., and Rees, M. April 27, 1920. Percussive drills.-For removing dust from a bore hole a divided hinged cylinder A fastened by a clip is placed round the drill, being packed by a divided rubber ring, and carries a branch B joined to a suitable pipe. A compressed-air jet C is used to suck out the dust.
