Abstract
430,583. Percussive tools. WOLF & CO., Ltd., S., and RICHARDS, H., 115, Southwark Street, Blackfriars Bridge, London. March 5, 1934, No. 445. [Class 124] A rotary drill 1 is converted for use as a percussive drilling unit by the substitution of the front end 6. This contains a face cam 16 rotated by the drill spindle through gearing and engaging a fixed cam 15. The blow is struck by a spring 21. The steel 9 is intermittently rotated by the pawl 24, which is eccentrically mounted on the rotating shaft 22.
