Abstract

1,042,780. Drill string joints. RUMANIAN MINISTRY FOR THE PETROLEUM AND CHEMICAL INDUSTRY. Sept. 28, 1964 [Sept. 27, 1963], No. 39463/64. Headings F2G and F2U. In a drill string joint the end of an upper pin member having an elliptical portion 2 and a smaller cylindrical end 4 with an intervening recessed portion 3 is inserted into an elliptical bore in the end 7 of a lower box member having side openings into which are inserted locking members 6 with lugs at their lower ends entering the recess 3, the members 6 being held in position by an encircling spring 15 and an external sleeve 11 and locking ring 12. The arrangement permits drive in either direction of rotation.
