ABSTRACT:
A drum cutter includes a machine body having at the opposed ends, pivot shafts extending parallel to the mine floor at right angles to the direction of travel by the machine body along a coal face. Two support arms each include two laterally-spaced bores at one end thereof to selectively receive a projected portion of a pivot shaft extending toward the mine face. A lever is mounted onto each of the support arms adjacent the bores in the end thereof. A cutter drum projects from the free ends of the support arms at the coal side of the machine body. Hydraulic jacks, supported by the machine body, are coupled to the levers for pivoting the arms to position the cutter drum supported thereby. A motor is supported within a casing attached to the stow side of each support arm. The motor is coupled through gearing to the cutter drum. The projected end of the casing is supported by a bearing member secured to the extension of the machine body and provided with a bore to receive the pivot shaft.
