Abstract

120,010. Aktiebolaget Atlas Diesel, and Andersson, G. Oct. 25, 1917. Percussive drills.- In a pneumatic rock drill with a rotatable cylinder and passages disposed in the wall of the cylinder whereby water is supplied to the hollow bit, packings are provided at the junctions of the passages. In the form shown, the cylinder 1 is enclosed in an outer slidable casing 17 and is intermittingly rotated therein by a reciprocating piston 22 engaging with a ratchet ring 23 which acts through pawls carried by the rear head 27 of the cylinder. A nozzle 35 carried by the casing 17, extends, with packings, into the rear head 27 and supplies water through passages 29, 26, 28, a screw nipple 32, packing 33, and the anvil block 3 to the hollow drill 6. Packings 30, 31 are provided at the junctions of the passages 29, 26, 27.
