Summary:A mineral winning machine composed of a frame slidably guided in gantry-fashion on a conveyor and a carriage displaceably supported within a guideway at the top of the frame. The separation between the carriage and guideway tapers to permit the carriage to move from side-to-side in a horizontal plane under the action of two piston and cylinder units. The carriage supports an arm pivoted to swing in a vertical plane under the action of a further piston and cylinder unit and two rotatable cutting cylinders are disposed on a shaft at the end of the arm. Each cutting cylinder is of cage like construction and formed from two axially offset rings adjoined to the shaft by radial spokes and interconnected by transverse webs. The rings and webs carry cutter bits and during use, mineral detached from a face can pass into the interior of the cutting device to be subsequently thrown out into a conveyor by the movement of the webs.
