Abstract
173,261. Elder, J. Aug. 13, 1920. Junction-pieces; branches and mains, connecting; spigot-and-socket screwed joints.-A coupling suitable for jointing two or more pipes situated in cramped positions, comprises a body 35 screwed to one pipe 37 and containing a nipple 34 with a tapered screw-thread at each end and adapted to engage, in making the joint, with screw-threads on the body 32 and the second pipe 20. The clearance in the body for the longitudinal movement of the nipple is at least equal to the combined length of the threaded portions of the nipple. The coupling with modifications may be employed for connecting three or four pipes or establishing a cross-connection between two parallel pipes. In the case of a four-way coupling, two of the nipples may be nested one within the other during transport. In a further modification, a wedge-shaped bushing 43<1>, Fig. 11, is inserted between the body and the nipple, the screw-threads on the surfaces of the bush being of opposite bands to ensure that the screwing up of the nipple tends to tighten the bushing in the body of the coupling.
