Abstract

937. Jacques, G. June 17, 1909, [Convention date]. Percussive drills.-In a hammer drill, a conical part on the front of the piston. directly or through a ball 11, oscillates a spring - pressed arm g carrying a pawl 7 engaging a ratchet 6 on the tool-holder, and sc rotates the tool. A pawl 13 prevents reverse rotation. A guard 15 is provided.
