Abstract

20,894. Hall, R. W., and Pearse, D. Sept. 26. Drills.-A rotary coal-boring machine for drilling long holes against water or gas in mines is secured in place by means of a flanged tube K, engine packing P, wooden lagging O, cement J, and a pair of backstays E. A hand-pump T supplies water through a sleeve C, the drill rods, a non- return valve N in the bit, and back through the tube K and stop-valve R to a discharge cock not shown.
