Abstract

842,701. Mineral-mining machines. COLMOL CO. May 29, 1956, No. 3344/60. Divided out of 842,700. Class 68(1). The boring heads of a mineral-cutting machine are so mounted on a mobile chassis that the heads can be advanced forward into a mineral seam a limited distance, the chassis remaining stationary during movement of heads. For further details of the construction of the machine see Specification 842,700, which is referred to.
