1,026,097. Mineral-mining picks. CHARBONNAGES DE FRANCE. Aug. 4, 1964 [July 23, 1963], No. 30692/64. Heading E1F. The disposition of picks in groups spaced from each other axially of and about the curved periphery of a cutter drum is such that in the face of mineral being mined by the drum there is formed by each group of at least three picks a groove having a width equal to the combined, individually equal, cutting widths of the picks, each groove having a depth not less than the thickness of the ridges left between adjacent grooves.
