Abstract
232,522. Burton, N. S. Dec. 12, 1924. Bore-hole apparatus. - In well-drilling apparatus the drill pipe has at its lower end a double pin 11, 13, a drill joint 14 being threaded to the smaller pin 13 and carrying at its lower end a preferably fish-tailed bit, while a sleeve 12, snugly fitting the joint 14 is threaded to the larger pin 11 and has formed on its outer surface reamer blades 17, the bevelled lower ends of the blades projecting below the sleeve; the water supply port 15 in the drill pipe communicates with ports 16, 19 in the sleeve, whereby jets of water are supplied immediately in advance of the reamer blades and at both the upper and lower ends thereof. The drill joint 14 has a wrench square 26 below the sleeve.
