Abstract

474,379. Rock-drills. STEVENS, A. H. (Cleveland Rock Drill Co.) April 29, 1936, No. 12189. [Class 124] A rock drill 96 is mounted to slide on a guide 74 which is carried on a tube 60. This tube is mounted to rotate about its axis in a casing 56 by worm gearing, and the casing can itself turn on a second casing 43 by loosening bolts 59. This casing is mounted to turn on a tube 39, the ends of which are secured to members 40 which can be adjusted in position in the circular grooves in the member 35 attached to the trolley frame 20. The angle between the frames 74 and 60 can be adjusted by the screw 89, the upper end of which is secured by an adjustable clamp 93.
