Abstract

24,707. Dehu, A., and Pestiaux, E. Oct. 31, 1912, [Convention date] Coal-cutting machines. -In a mining-machine of the type comprising a pair of parallel boring-tools 2 and an intermediate cutter-bar 1, the tools and their operating mechanism are mounted on a carrier sliding in guideways on a base member 13. Debris is conveyed away by screw - threads 17. The tools are driven by a motor 7 which also drives a feed - nut 15 moving on a stationary spindle 14.
