Abstract
1275537 Boring earth &c ATLAS COPCO AB 30 April 1971 [30 April 1970] 12467/71 Heading E1F In a core drill having a core barrel (not shown) transported through the drill stem 1 by a wire line tool 8, a latch 6 has parts 9, 15 respectively engaging forwardly and rearwardly facing shoulders 11, 17 on the stem to hold the barrel during coring and has a part 10 engaging the tool during transport. Two latches pivot on a pin 7 carried by a swivel 4, supporting the barrel, the latches being urged by a spring 16 to engage the tool which has a latch-release sleeve 14. In a modification the latches engage within a hollow depending part of the tool.
