Abstract

226,925. British Flottmann Drill Co., Ltd., and Sgonina, A. Nov. 12, 1923. Percussive tools. - Live fluid for clearing the bore hole is supplied independently of the actuation of the tool by means of a pipe d on which the piston slides and which is spring mounted in a recess to which fluid is supplied by an inlet i. On depressing the pipe against the spring f the ports h, k register and fluid passes to the bore hole. The pipe d may be constructed as described in Specification 226,924.
