Abstract

175,542. Rayner, G. H. T., and Rayner, P. Feb. 25, 1921. Drills.-A hand or power driven drill for operating on rock or coal is attached to a support p which can turn on ball bearings round a central fixed support a. A toothed ring or segment f, which may be renewable, is bolted to the support a, and a worm 7, mounted in a box u, is carried by the support p and gears with the ring f. To adjust the worm horizontally and vertically, lateral play is provided, as shown at w and 4, round the bolts which hold the box to the support p. A handle (not shown) is attached to the worm shaft.
