This is a coupling arrangement which is usable in an overhead irrigation system of the traveling or moving type more commonly known as center pivot and laterally moving irrigation systems. The present coupling arrangement is connected between the slightly spaced ends of two pipes which are generally aligned. A flexible coupling in the nature of a mechanical interlock is positioned within and between the ends of the pipes and a sealing arrangement is disposed around the coupling with the coupling itself being constructed and arranged to provide for and accept misalignment to some degree between the pipes and also for some swiveling. This is also an alignment arrangement for irrigation systems.

In a pipe joint, two generally axially aligned pipes terminating in planar ends which are in substantial spaced relation to each other, a gimbal ring between the pipe ends and of an outside diameter on the order of and no greater than the outside diameter of the pipe ends and of an axial extent such that it does not axially overlap the pipe ends, two pairs of coupler bars, 180°apart having inner and outer ends, and means connecting one pair at their outer ends to one of the pipe ends and the other pair at their outer ends to the other pipe end and means pivotally connecting said bars at their inner ends to the gimbal ring, one pair being spaced about 90°from the other such that their pivot axes are generally perpendicular to each other, and a sealing sleeve in sealing engagement with said pipe ends and surrounding the ends of both pipes, the gimbal ring, and the coupler bars.
