Abstract
Abstract A concentric member assembly and an improved method of fabrication thereof including inserting a hollow, externally conically tapered, preferably shouldered wedge means into each end of a preferably metallic, permanently deformable inner elongate tubular member generally centrally aligned within an elongate, preferably metallic tubular outer member to selectively expand the inner member ends into intimate contacting engagement with adjacent internally cinically tapered portions of the outer member inner surface. The wedge means may be suitably arranged either for removal from the inner member after use, or, alternatively, for retention therewithin to provide additional support therefore. The outer member may be inwardly deformed adjacent each of its ends to engage either the adjacent inner member end or the wedge means retained therewithin. The resulting structure may be advantageously employed as a multiple sleeve connecting device or the like.
