Abstract
A cutter assembly for a continuous miner adapted for use in the underground mining of coal. The cutter assembly includes a frame adapted to be pivotally supported by the continuous miner, a pair of spaced apart, generally longitudinally directed augers supported by the frame and a transverse auger extending generally between the longitudinally directed augers and rearwardly thereof. The longitudinally directed augers include cutters disposed at the forward end thereof which are adapted to be rotated into cutting engagement with a coal face or seam. A generally U-shaped pan supported by the frame is disposed below the longitudinally directed augers and the transverse auger and has an upwardly slopping rear wall which permits coal to be fed upward to a receiving belt. Drive means are provided for imparting a rotational force to the longitudinally directed augers and the transverse auger.
