Abstract

1,115,827. Mineral-mining picks. GEWERKSCHAFT EISENHUTTE WESTFALIA. 7 Nov., 1966 [8 Nov., 1965], No. 49780/66. Heading E1F. A mineral-mining cutter plate, preferably trapezoidal in shape, is provided with a protuberance that, when the plate is entered into a socket in a shanked holder, enters into an aperture in the leading wall of the socket to hook into the aperture to retain the plate in abutting relationship with the rest of the socket against forces acting on the plate during cutting of mineral thereby.
