Abstract

227,664. Holman, A. T., and Holman, K. J. March 3, 1924. Forging and sharpening rock drills; dies.-In a forging-machine for shaping and sharpening rockdrills of the type wherein the drill bit is held between a pair of jaws while a reciprocating dolly operates on its end face, the movable jaw is connected to a pair of pistons arranged in tandem. The jaws 19, 22 are carried by a piston 14 and the top of a cylinder 11 respectively, a piston 13 in the cylinder 11 being connected by a rod 15 to the piston 14 which has side extensions engaging recesses in the cylinder 12 to prevent rotation. A third piston 31, engaging but unconnected with the rod 15, is actuated by a constant-pressure air supply to open the jaws. The jaws may also carry dies 33, Fig. 3, to shape the drill-bit before it is acted upon by the dolly 25, and a gauging stop 36, adjustable at 37, determines the penetration of the work into the conical die to limit its diameter. The dies and acting surfaces of the jaws are secured to the piston and cylinder by bolts 35, end plates 34 and undercut recesses 20.
