Abstract
695,010. Percussive drills. HOLMAN, BROS., Ltd., HOLMAN, A. T., ORAM, M., and JAMES, E. B. Dec. 27, 1950 [June 19, 1950], No. 20472/52. Divided out of 694,963. Class 124. A dust eductor system for mines wherein the dust created at the drill bit is removed by suction comprises a common conveyer pipe line connected to a number of drills by hose pipes and terminating in a vacuum creating apparatus. As shown a series of drills D<SP>1</SP>-D<SP>6</SP> are connected by hoses to valved points DU<SP>1</SP>- DU‹ on a pipe line P which is connected at its other end to a cleaning system CS<SP>1</SP>, CS<SP>2</SP>, F and an extractor fan VG. The cleaning and vacuum creating systems may be situated at some distance from the rock being drilled. The cleaning system may comprise two cyclone separators CS' and CS<SP>2</SP> and a filter F. A vacuum relief valve 15 may be included in the pipe line. The drills used may be of the type described in Specification 695,009. Specification 694,963 also is referred to.
