Abstract
1,232,932. Shaft couplings. PHILLIPS PETROLEUM CO. 14 Feb., 1969 [16 Feb., 1968], No. 8157/69. Heading F2U. A telescopic coupling for a drill line is provided with an external sleeve of sufficient length to totally enclose the coupling when fully extended and also provide additional stiffness against lateral bending. As shown the ends of adjacent pipes 12, 13 carry screwed sleeves 14, 24 with a splined connection 24, 25, extension of the members being limited by a bush 22 screwed on to the lower end of sleeve 14 and providing an abutment shoulder 23 for a flange at the upper end of sleeve 24. The external protective sleeve 33 is attached at its upper end to a screwed adapter 17 between pipe 12 and sleeve 14.
