Abstract

1,040,566. Mineral-mining machines. COAL INDUSTRY (PATENTS) Ltd. Nov. 9, 1962 [Nov. 14, 1961], No. 40684/61. Heading E1F. On the self-advancing body of a mining machine is so pivotally mounted an arm that it can be swung in a plane parallel to a face of mineral to be cut and the arm carries one or more driven rotary cutters that rotate about an axis or axes parallel to the pivotal axis of the arm and on each cutter is mounted one row only of picks, which extend forwardly of the cutters to remove a shallow cut of mineral from the face as the arm is swung parallel to the face.
