Claim 1

THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS: 1. A method for joining a plurality of plate-like structures parallel to each other, including, forming aligned holes through the plate-like structures, forming each of a series of generally cylindrical metallic bodies, (a) with a diameter larger than the diameter of the aligned holes, (b) with an axial bore extending inwardly from one end of the body, and (c) with a neck extending outwardly from the other end of the body and having, (1) its outward end with a diameter substantially that of the aligned holes through the plate- like structures, and (2) its section between the face of the body from which the neck extends and its outward end reduced in diameter, inserting the neck of each body through the hole in one of the plate-like structures and extending the neck into the axial bore of a second of the bodies in capture of the plate-like structure between the end faces of the two bodies, and upsetting the second body from external of the body on its axial bore end so as to protrude a portion of the second body intotthe section of reduced diameter of the neck to lock in union the adjacent bodies for permanent capture of the plate-like section between them.
