Abstract

1,067,035. Mineral-mining machines. COAL INDUSTRY (PATENTS) Ltd. Feb. 17, 1964 [April 16, 1963], No. 43437/62. Heading E1F. To eliminate sparking and wear of the cutter tip of a cutter tool moving in a circular path the drive of the mineral-mining machine for said tool is such that the linear velocity of any part of the tool does not exceed 300 feet per minute. Preferably the velocity is in the range 60-120 feet per minute. Such a drive is incorporated in a cutter drum machine as disclosed in Specification 1,040,566.
