Abstract
3140. Krolik, J. Feb. 15. Drilling.-A hand-driven machine for cutting coal comprises a number of rotary drills mounted in a casing which carries two disk cutters, the casing being advanced and the drills and cutters rotated by means of the same shaft. A screwed spindle c mounted in a frame a and driven by wheel gearing b carries at its outer end a casing e which may slide forward and is prevented from turning by means of guide-rods g. The spindle c and shafts o, p journaled in the casing e carry cutting-bits and are rotated by means of sprocket-wheels m, x, n, y and chains z. The disk cutters k, l, carrying detachable cutters q, are mounted on a vertical shaft driven from the spindle c by means of a worm h and a wheel i.
