Abstract

323,963. Marks, Sir G. C., (Ingersoll- Rand Co.). March 5, 1929. Percussive tools. - In order to put the twist mechanism into or out of action as desired, the head 0 of the twist-bar co-operates with a ratchet ring R which may be held fast by turning a rod U into the position shown, so as to engage one of a number of grooves W in the ring. To put the twist mechanism out of action, the rod U is turned to bring a recess Y therein adjacent the ring, when the latter is free to turn in its seating S. The device is stated to be advantageous for broaching between adjacent holes or for reinserting a drill into a deep hole.
