Abstract

1305004 Boring earth &c INSTITUT GORNOGO DELA SIBIRSKOGO OTDELENIA AKADEMIINAUK SSSR 22 April 1971 10662/71 Heading E1F A pneumatic ground-burrowing device comprises a housing 1, a striker 2, an air supply member 7, and working chambers 5, 6. When the device is burrowing the pressure of the supply forces a slide 11 to move to close holes 10 so that air is supplied to and exhausted from the chamber 5 through holes 9, the striker reciprocating and striking the pointed end of the housing. During withdrawal of the device the pressure of the supply is reduced to permit a spring 15 to move the slide to the position shown, the striker reciprocating and striking the end of the housing formed by a flange 8 on the member 7.
