Abstract

1279112 Rock drilling apparatus GARDNERDENVER CO 23 June 1969 [20 March 1969] 59605/71 Divided out of 1279111 Heading B4C The subject-matter of this Specification is identical with that described in Specification 1,279,111, but the claims are concerned with a rock drilling apparatus in which a rock drill is fed reversibly along an elongate support by means of a feed motor, and in which conduit means in communication with a pressure fluid source and the feed motor for supplying fluid to feed the drill forwardly along the support includes automatic regulator means which in operation continuously regulates the pressure of fluid supplied to the motor to a predetermined percentage of the pressure of fluid supplied by the source.
