Abstract

186,935. Peters, W. W. Oct. 6, 1921, [Convention date]. Drills; chucks; sockets.-Broken ends of twistdrills, milling..cutters, reamers, wood-bits, &c. are utilized by grinding square the end of the broken piece and securing it in a chuck by means of a collet. Various forms of collet are described. The brass &c. collet 11, Fig. 2, is cast in the end of the drill 10, and is subsequently turned to fit the socket. In some cases the cast socket may be removed from the shank for general use. In the case of drills &c. with plain shanks, grooves or flats may be ground in or on the shanks to provide additional grip for the cast metal. The collet may also be formed in halves, 21, Fig. 5, or in quarters, 23, Fig. 7, the terminal portions being shaped so as to engage the flutes of the drill &c. A split ring 26, Fig. 8, may be used to retain the various sections of the collet in their assembled positions. In each form the collet is provided with a groove 16 for driving engagement with a feather 19, Fig. 2, on the chuck, the collet being secured in the latter by means of a screw cap 17.
