Abstract

356,438. Percussive drills. RAYNER, G. H. T., 14, Broomhall Road, and RAYNER, P. T., 37, Ashland Road, both in Sheffield. Aug.16,1930, No. 24611. [Class 124.] In a fluid-actuated percussive tool having the distributing valve chamber 14 formed between the cover 13, and a bearing member 11 keyed to the cylinder, the valve and the twist mechanism 6, 9 being concentric with the cylinder, the pressure fluid at the rear end of the cylinder passes through the twist mechanism and holes 21 in an abutment ring 4. This ring and the ratchet ring 9 are keyed together and to the ring 11, to prevent rotation. A tube 24 supplies flushing water to the drill.
