Abstract

733,596. Earth-boring apparatus. COCHRAN, J. F., MIDDLETON, J. I., and JAQUES, N. D. Sept. 14, 1953, No. 25359/53. Class 85. An irisert E in an earthboring drill string may function as a stabilizer, a centraliser, or a fulcrum to the drill string, and comprises a tubular steel body E of at least the same outside diameter as the adj acent portions of the drill string, a plurality of ribs G detachably mounted on the body E, and shoes J, faced with wear-resisting material 46, secured on the ribs G. The shoes J, which have curved faces concentrically disposed about the axis of the body E and lower end portions extending inwardly towards the body, are formed to fit on projections 50 on the ribs G, which are circumferentially spaced around the body at an angle to the axis thereof. Each rib is formed of an easily drillable material, and has a tongue 31 to engage a groove 30 in the body, the tongue 31 and groove 30 having complementary tapers in an upward direction. Stops 39, 40 limit the movement of the tongue in the groove.
