Abstract

1,006,819. Mineral-cutting picks. CHARBONNAGES DE FRANCE. June 5, 1964 [June 20, 1963], No. 23479/64. Heading E1F. To allow of dust suppression by water spraying water is passed along a longitudinal passage 1 through the shank 2 of a mineral-mining pick to enter through a section of reduced diameter a cylindrical central portion 3 of a bore at right angles to the axis of the bore which extends transversely through the head of the pick and has an outwardly divergent portion 32 at each end of the cylindrical portion, the length of which is less than the diameter thereof. The water on entering the central portion is atomized as it strikes the wall of the central portion.
