Abstract

221,934. Reichwald, A. W., (Schweitzer, E.). Aug. 24, 1923. Drills.-In overhead boring in mines &c., particularly for the formation of blind shafts, and wherein a boring apparatus is carried by an extensible boring bar, a frame 2 is carried by the boring bar 1, and the boring apparatus 5, which may be rotary or percussive, is secured to the 'upper end of the frame by a gimbal ring device 7, 9. so as to be freelv movable in all directions, the centre of gravity of the boring apparatus being placed below the gimbal ring device, whereby the boring apparatus automatically assumes a vertical position. The percussive boring apparatus shown is supplied with actuating fluid from the boring bar 1 through flexible tubes 11.
