Abstract

171,916. Hundrieser, H. Dec. 29, 1920. Drilling-machines; drills.-A tubular rock drill c is rotated by either of two bevel pinions i, h, a nut d on the central fixed spindle b being simultaneously rotated so as to feed the drill. The end of one of the pinion shafts is guided so as to be prevented from rotating as the housing k advances with the drill. The larger pinion i is used for withdrawing or for giving a quicker feed in soft rock. The stepped formation e is to accommodate drills of different sizes.
