Abstract

338,146. Abegg, W. A. June 13, 1929. Borehole apparatus.-In a. well-boring drill of the roller cutter type, the cutter 12 and a bushing 13 have registering annular grooves 22, 21, an opening 40 leading through the cutter to the groove 22. The notched end of a heated member 23 is inserted through the opening 40 and the notch is engaged by a pin 30 inserted through an opening 31 in the bushing. The cutter and bushing are then relatively rotated so that the member 23 is drawn into the grooves 21, 22, the member 23 being then cooled by oil &c. admitted through the opening 40, whereby the member 23 is shrunk on to the bushing and holds the bushing and cutter against relative axial movement. The openings 31, 40 are then plugged. A flange 17 is provided at the outer end of the bushing, the flange being provided with notches 19 to receive a tool to facilitate threading the bushing on to a stud 15. The flange bears against a washer 20.
