Abstract
1,129,051. Mining machines. COAL INDUSTRY (PATENTS) Ltd. 8 Nov., 1965 [6 Nov., 1964], No. 45353/64. Heading E1F. The picks mounted on the end face of an axially sumpable, rotary cutter head of a mining machine project ahead of the end face to beyond the forward reach of a ring of picks mounted around the periphery of the end face, all of these picks being so disposed on the end face that the orbital path of the point of each pick is separate from that of the other points.
