Segmented transition coupling
First Claim
Patent Images
1. A coupling segment for use in conjunction with an identical coupling segment to provide a transitional segmented pipe coupling;
- said coupling segment having end faces respectively inclined oppositely relative to an X-Z plane of said coupling segment; and
,means at one end only of said coupling segment prohibiting assembly of said one end of said coupling segment to a said one end of an identical coupling segment;
said means comprising an abutment integral with said one end of said coupling segment and positioned adjacent one axial side of said coupling segment, and a projection integral with said one end of said coupling segment and positioned adjacent an opposite axial side of said coupling segment;
said abutment and said projection each being positioned radially outwardly of the associated said end face;
said projection extending perpendicularly above the adjacent surface of said end face in a direction tangential to said coupling segment;
said projection being freely moveable relative to an opposite end of an identical said coupling segment to permit both axial movement of said one end in the direction of the X-X axis of said coupling segment, and also to permit rotational movement of said coupling segment about the Y-Y axis of said coupling segment.

Abstract
Coupling segments of a segmented pipe coupling have dissimilar ends that are interfittable with ends of an identical said coupling segment in only one specific orientation of said coupling segments, and which are antagonistic to the interfitting of said ends of said coupling segments in all other positions of orientation of said coupling segments.
