Abstract

324,958. Rayner, G. H. T., and Rayner, P. Nov. 7, 1928. Percussive tools.- A rock drill or the like is provided with a flat annular distributing valve h operating in the manner described in Specification 321,182 and mounted to surround the water tube 11. Twist mechanism is mounted at the forward end and comprises a sleeve 6 which is oscillated by the action of grooves 5 in the piston, which itself is prevented from turning, and rotates the tool holder 9 step-by-step by pawl - and - ratchet gear. Auxiliary exhaust ports x, y in the cylinder, or z, z<1> in the piston, may be provided.
