Abstract

575,664. Work-holders for grinding machines. CLARK, R. H. March 30, 1944, No. 5906. Convention date, March 1, 1943. [Class 60] A block is furnishec with a socket for re ceiving the screw-cut ting tool to be ground and with faces and back at such angles thereto that the tool is cor rectly presented to the grinding wheel when the block rests on the appropriate face. As shown, the tool C is secured in the socket by screws 15 and the block has pairs of faces A, B, on opposite sides and a sloping back 13 ; the base has two faces 22, 23. The faces A are at an angle of 60‹ for standard V threads, the faces B, for Acme threads being at 29‹. When the block rests on the face 22, a surface 20 parallel to the axis of the tool is ground ; when the surface 23 is used a downwardly and rearwardly sloped surface is ground. The surface 13 is used for grinding a front surface on the tool for forming the root of the thread. The tool may be secured in the socket together with a member 60, Fig. 10 having a sloping surface 62 for offsetting.
