Abstract

319,179. Brunzel, K. Feb. 7, 1929. Percussive drills.-The finer dust is sucked out from a bore hole through the hollow drill shank 4, through which a current of air is induced by the exhaust air from the drill, which is provided with pipes 24, 25 connecting the exhaust ports 1<1> with an injector device 23 whereby air is sucked through the shank to a space 17 and thence to an outlet 26. The space 17 is formed in a yellow metal ring carried between packing washers in a two-part housing 12 on the front end. The larger particles of dust are left to work their way out along the drill shank. In a modified device the conduit for the suction-inducing current is inside the barrel. The shank is suitably perforated as at 32, for the passage of dust.
