Abstract
694,963. Percussive drills. HOLMAN BROS., Ltd., HOLMAN, A. T., ORAM, M., and JAMES, E. B. Dec. 27, 1950 [June 19, 1950], No. 15256/50. Class 124. A dust eductor system for dry drilling apparatus comprises a hollow drill steel, a drill having a passage aligned with the steel and passing straight through the drill, a hose connected to the back of the drill and delivering to a filtering unit, and a vacuum creating device to establish a partial vacuum throughout the system. As shown, a hollow steel 2 having a bit 1 is connected to a drill 3 which has a straight through passage in communication with a pipe 5 discharging into a filtering unit 7a, 7c, 7e, the parts 7a and 7c collecting the larger particles and a bag 7e the dust. An ejector may be incorporated in the drill or in the pipe 5 adjacent the drill, and may start operating before the drill. The drilling may be transferred from the filtering unit to a wagon and removed. In a modification, Fig. 3 (not shown), the bag 7e may be replaced by a pipe discharging some distance away from the drill. The drill bits, Figs. 7-14 (not shown), are arranged with holes through which the drillings may be withdrawn from the drill hole, each of the holes in the bit being of a diameter smaller than that of the hole in the hollow steel. Specifications 695,009 and 695,010 are referred to.
