Abstract

330,433. Capeliushnicoff, M. A. July 13, 1929. Borehole apparatus.-In apparatus in which a boring tube 1 is rotated by a hydraulic motor from which the water then passes through the tube 1 to cool the tools and remove debris, a head 2 is threaded to the tube 1 and has depending jaws 3, 4 between which cutters 7, 8 are pivoted, the cutters having toothed segments 9, 10 engaging teeth 15 on a piston 13 sliding in the boring tube 1 and controlling ports 12 leading to a recess 11 in the head 2; ports 18 lead from the recess to the cutters. Stops 19 limit movement of the cutters. In use, on admitting fluid, the piston 13 is first depressed to expand the cutters and thereby opens the ports 12 to permit circulation of the fluid, so giving an indication above ground that the cutters are expanded.
