Abstract
670,816. Mining-machines. MARCEROU, P. Nov. 3, 1949. No. 28134/49. Class 68 (i). A rock cutting machine comprises two parallel disc cutters 12, 13 located at a distance from one another and equidistant from either side of a carrier and driving arrangement 1, 2, 3 provided with a conical cutter 21 and two drum cutters 17 mounted one on each of the other two sides of the carrier 1. The cuts made by the cutters 21, 17 connect up with those made by the cutters 12, 13 so that the carrier and driving arrangement may enter the face. All the cutters are simultaneously driven from the shaft 3 by suitable bevel gearing mounted in the carrier. Rotary borers may replace cutters 17, 21.
