Abstract

214,171. Arbon, P. Nov. 8, 1923. Bore - hole apparatus.-In well.drilling apparatus, the temper screw is operated by a member M carrying a bevelled spring-pressed pawl L<1> engaging a ratchet wheel W. on a collar secured to the screw by set-screws A; the pawl is rotatable in its housing so that it may drive the collar in either direction or lock the member M and collar against relative rotation in either direction.
