Abstract: Structural connector for tubular members used in trusses and the like comprises a one-piece forged element comprising at least a portion of a tubular primary member with a longitudinal central axis and a pair of first and second tubular secondary members integrally connected to one side of the principal member. The secondary members have longitudinal central axes coplanar with the axis of said portion of said primary member and the axes of the secondary members intersect each other at a point displaced to the same side of the axis of the primary member where the secondary members intersect one another.

Abstract: In a connector, as used to interconnect structural members in a trusswork, an elbow and a pipe, which may be another elbow, are provided with suitable slots receiving a plate, and the elbow, pipe, and plate are welded together.

Abstract: In a double-sigmoid connector, as used to interconnect structural members in a trusswork and comprises a pair of arcuate elbows joined to each other at their outer peripheral midsections, a pipe extends through an opening in the outer peripheral midsection of each elbow and is joined to each elbow so as to join the elbow to each other.
