Abstract
695,009. Percussive drills. HOLMAN BROS., Ltd., HOLMAN, A. T., ORAM, M., and JAMES, E. B. Dec. 27, 1950 [June 19, 1950], No. 20471/52. Divided out of 694,963. Class 124. A rock drill for dry drilling has a straight tube located between an outlet at the back of the drill and an orifice in the anvil and is supported at one end in the anvil and at the other in a sleeve passing through the valve chest so that dust passes from the drill bit through a hollow steel and the tube to the back of the drill. As shown, a straight tube 3a is supported at one end in an anvil 3b and at the other in a sleeve 3c which may be so fitted in an outlet passage 8 at the back of the drill to form an ejector. The internal diameter of the tube 3a may be greater than the diameter of the hole in the steel. Specification 694,963 is referred to.
