Abstract

1,252,128. Mineral-mining picks. AUSTIN HOY & CO. Ltd. 18 Nov., 1968 [22 Nov., 1967], No. 53263/67. Addition to 1,142,141. Heading E1F. To permit of a mineral-mining pick being mounted on a projection of a machine-mounted support comprises a body 2 having a circular cross-section recess 6 of a diameter at its inner end that is not substantially less than the diameter at its outer end and one or more cutter edged projections 3 extending from the body forwards in the direction of the motion to be of the body and each being of smaller dimension than the body in a direction at right angles to said direction. The projections may be symmetrically or asymmetrically arranged on the body. The recess and body preferably have complementary taper. A water passageway extends from the recess through the body which has at the rear a pierced tongue 1 for securing in a recess in the projection.
