Abstract
1296924 Boring earth MISSION MFg Co 24 Feb 1970 [6 March 1969] 8918/70 Heading E1F A percussive drill bit has first cutter elements 14 on the bottom surface and at least one gauge cutter 57 movable sideways of the bit by the percussive drive means. The or each cutter 57 comprises an insert on a plunger 53 urged by a spring 55 so that a boss 58 extends into a passage 59. When fluid pressure in lower working chamber 39 and thus in passage 59 is high enough, the boss moves out of the passage allowing the fluid pressure to act against the whole cross-section of the plunger to cause the insert to move outwardly to engage the side of the hole. The bit is percussed by hammer piston 24 reciprocated by fluid alternately entering upper and lower working chambers 36 and 39 through supply ports 42, shuttle groove 27 and ports 34 and 35 or 37 and 38 respectively. The fluid in the chambers 36 and 39 is exhausted when piston 24 uncovers ports 44 and 45 respectively leading to an exhaust passage. In a modification passage 59 may be connected to upper working chamber 36.
