Abstract

542,450. Hollow rivets. LINREAD, Ltd., and LYNALL, E. H. July 25, 1940, No. 12132. [Class 89 (i)] [Also in Group XXII] Tubular rivets and distance pieces, particularly those of aluminium alloy are bent up, from sheet metal, with a longitudinal seam provided with closely fitting dove-tailed interlocks. A blank, Fig. 5 is first bent up to the section shown in Fig. 8 and then whilst supported on a mandrel is rolled up into tube form and whilst the blank is supported also at its ends sufficient pressure is applied to cause the metal to interlock at the edges also as shown for example in Fig. 9. More than one dove-tail may be provided.
