Abstract

510,214. Percussive drills and holders; handle fixing. RAWLINGS, J. J., and RAWLPLUG CO., Ltd. April 5, 1938, No. 10378. [Classes 61 (i) and 124] A holder for percussive drills and the like has a tapered or other bore 3 corresponding to the shape of the tool shank and a projection 4 for engaging a flat on the shank. The projection may be made by drilling a hole 1 so as to leave a thin wall which is deformed. A transverse bore 5 serves for a wedge driven in to displace the tool from its holder.
