ABSTRACT:
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.
