Abstract
522,765. Percussive drills. CLIMAX ROCK DRILL & ENGINEERING WORKS, Ltd., and ST. STEPHENS, R. DE H. Dec, 15, 1938, No. 36606. [Class 124] In percussive rock drills having a water supply tube passing through the anvil block into communication with the hollow bore of the drill steel, the anvil block is provided with a recess at its striking end or has an extension member with a recess and the drill steel fits into. the recess. The water tube e passes through the piston b into the anvil block c which has a recess h, or an extension member l with a recess n, and the drill steel d with hollow bore g fits snugly into the recess to prevent entrance of air. The extension member may be a block of rubber recessed so 'that the drill steel fits into it and is in contact with the striking end m of the anvil block proper.
