Abstract

14,592. Hopkinson, E., and Hopkinson, A. A. June 29. Undercutting &c.-A tool-holder for use in connection with coal-mining machines of the chain-cutter type is made in two parts hinged together and provided with a recess for the reception of the end of the tool, the two parts of the holder being held in closed position by means of a pin. A link part A attached to the chain by means of pins is provided with a saddle-shaped piece H, and carries a hinged cover B formed with an aperture D and a recess d in which may fit the out-turned end e of the tool E. When the cover B is in closed position, a pin is inserted in the holes J and serves to lock the cover B and the part A together. In a modification, the part B is provided with two holes in which may fit two cutting-tools.
