Abstract

1313899 Earth boring impact tool INSTITUT GORNOGO DELA SIBIRSKOGO OTDELENIA AKADEMII NAUK SSSR 9 July 1970 [19 Jan 1970] 33275/70 Heading E1F A pneumatically operated impact-action selfpropelled mechanism for driving holes in the earth comprises a housing 1 containing reciprocable impact member 2 engaging stepped sleeve 7 mounted in housing 2 by shock-clamping elastically-deformable bush 9. In use, compressed air from hose 14 enters chamber 6 and drives member 2 forward to strike housing 1. Ports 8, uncovered just before the impact, pass compressed air to chamber 5 to return the rebounding member 2 against the resistance of the compressed air in chamber 6. At the end of the return stroke air exhausts from chamber 5 through ports 8 and passages 13 in the bush to atmosphere. The operating cycle is then repeated.
