Abstract

1,231,317. Drum-type mining machines. EICKHOFF MASCHINENFABRIK U. EISENGIESSEREI m.b.H. GEBR. 5 Aug., 1969 [22 Aug., 1968], No. 39027/69. Heading E1F. A coal-cutting machine comprises a cutting drum 3 and a clearing plate 6 which is pivotally mounted adjacent one end by pivoted links and, intermediate its ends, by struts 16 to the body of the machine for movement by a ram 8 between a position in which it extends transversely to the direction of travel of the machine and a position in which it extends substantially in the said direction. A second similarly mounted and operated clearing plate 7 is provided, the plates 6, 7 being on opposite sides of the drum for alternative operation in dependence upon the direction of travel of the machine. Each plate has movable drop plates provided at its lower end.
