Abstract

1,141,616. Percussive drills. GEBR. BÍHLER & CO. A.G. 10 May, 1966 [10 May, 1965], No. 20639/66. Heading B4C. [Also in Division E1] In a deep-well drill activated by a hammer piston 7 reciprocated by compressed air controlled by a valve 12, air is exhausted, at each end of the piston stroke, through ports 9 into a tube 8 passing through the piston and its cylinder 4. The air passes through the drill-bit 16 for scavenging. Compressed air may be passed continuously down tube 8 and helps to eject the exhaust air from the cylinder.
