Abstract
247,445. Rawlings, J. J., and Rawlpug Co., Ltd. June 13, 1925. Fixing by self-grip sockets.-A handle a for a percussion tool such as a drill having a bore b serving as a tool socket is provided with a hole c extending obliquely from the end of the bore to the outside of the holder so that a punch or drift may be inserted therein for knocking the tool shank out of the bore. In the construction shown in Fig. 1 the oblique hole c is formed by drilling, and in that of Fig. 3 a recess d is milled at the outer end of the hole. Or, a recess e, Fig. 5, may be formed by stamping or punching.
