Abstract

1,086,701. Mineral-mining machines. COAL INDUSTRY (PATENTS) Ltd. Jan. 7, 1965 [Jan 10, 1964], No. 1248/64. Addition to 987,505. Heading E1F. The mining machine of Specification 987,505 is modified by the provision of two sets of attachment points on the cutter tool boomcarrying turret for attachment of a pair of jacks to rotate the turret about a vertical axis relative to the self-propelled chassis of the machine, this arrangement allowing of a more satisfactory swinging of the turret as compared to that of Specification 987,505.
