Abstract
472,062. Joining edges in making tubes or other structures. GLACIER METAL CO., Ltd., and BATE, J. April 24, 1936, No. 11730. [Classes 83 (ii) and 83 (iv)] In a method of interlocking the edges of metal structures, particularly tubes, the edges are formed with projections 1, Fig. 1, and recesses 3 which are shaped so that on pressing the edges together the projections engaging in the recesses are bent or deformed in a lateral direction to interlock with the recesses, each projection being shaped to have one straight side 1a, Fig. 1, disposed perpendicularly to the edge, and the other side 1b of curved shape, and the co-operating recess is of similar shape but with its straight side 3a disposed at a small angle to the perpendicular. The projections and recesses may be disposed alternately right- and left-hand and may be disposed alternately on opposite edges. Edges may be connected of single layer metal or of metal having two layers united together. Specification 6824/97, [Class 83], is referred to.
