Abstract
717,094. Coal-mining machines. GEWERKSCHAFT EISENHUTTE WESTFALIA. Sept. 5, 1952 [Oct. 27, 1951], No. 22422/52. Class 68(1) A coal-mining machine in which is incorporated a plough 12 is drawn to and fro'along the mine face 10 by endless traction means, e.g. a chain arranged in two runs, 13, 13<SP>1</SP> moving in separate guide channels 14, 14<SP>1</SP> which are arranged one above the other and are secured to the side of a face conveyor 20. The connection 15 between the plough and one of the runs of the chain extends through a slot 16 or 16<SP>1</SP> formed in the channels. The connection may be to one run only of the chain, the direction of motion of the chain being reversed at suitable moments, or the direction of motion of the chain may be constant and the connection changed, either manually or automatically, from one run to the other to reverse the motion of the machine. To assist in the guidance of the machine a claw 17 extends from the machine over a bar 18 secured to one or other of the channels 14, 141.
