ABSTRACT:
A standard pipe coupling is formed of two, semi-circular segments that are bolted together to form a circular casing which surrounds the adjacent, axially aligned, end portions of two pipes to be connected. The casing is U-shaped in cross-section to form an exterior base and radially inwardly directed legs which are of substantially equal length. The radially inner edge portions of the legs form continuous, annular, narrow tenons which normally fit into annular grooves formed in the exterior surfaces of the pipes for interconnecting the casing and substantially equal diameter pipes. A diameter reducing insert comprising a flat, thin, segmented ring whose outer peripheral edge is formed with a continuous groove is arranged coplanar with one of the legs, and with its groove receiving the tenon of that leg. The inner peripheral edge of the insert ring forms a tenon which is substantially the same shape and width as, and is aligned radially inwardly of, and coplanar with, the tenon of its leg for fitting within a groove of a smaller diameter pipe. Thus, a predetermined size casing can be used to couple a corresponding, predetermined diameter large pipe to a variety of different size, smaller diameter pipes by selecting an inert whose inner peripheral edge is matched to the size of the particular diameter small size pipe selected.
