Abstract

564,234. Percussive drills. JONES, J. R. June 15, 1943, No. 9533. [Class 124] For laying the dust produced by a percussive drill, the nozzle 17 of a water atomizer fits into the side of a metal cone 18, or conicalended cylinder, surrounding the drill steel 19 and fitting into the mouth of the borehole. The water may be atomized by means of compressed air from the supply which operates the drill.
