Abstract

184,817. Linneker, J. R. July 16, 1921. Drilling-machines. - A coal boring machine comprises a cutter spindle B slidably mounted in a frame A and driven from a motor C through gearing E, G, H, the cutter spindle being connected to a saddle J sliding on guide rods K and moved by a screw L to feed the cutter; the spindle B, guide rods K and screw L are in the same horizontal plane. The gear H forms a flywheel or an independent flywheel H<1> may be provided. The frame A may be turned by worm gearing P<1>, N<1>, about a vertical pivot N on a carriage O. Holes may be drilled out of line with the cutter spindle B by means of a drill socket R in an attachment S carried by the spindle, the socket R being driven from the spindle throughchain gearing T.
