GATHERING HEAD Abstract of the Disclosure. An improved rotating disc-type gathering head suited for use with underground mining machines includes at least two gathering discs mounted for rotation on an inclined apron in positive engaging relationship at their point of tangency. One of the discs is rotatably driven, preferably by means mounted above the apron. The second disc is rotated in the opposite direction by the first disc to provide the desired flow of mined material. In the preferred embodiment the discs have peripherally disposed intermeshing gear teeth, and the drive means comprises a pinion gear in peripheral engagement with the first disc. Additional gathering discs can be added without complicating the simple mechanical drive system below the apron. -1a-
