Abstract

120,042. Locomotive Superheater Co., (Assignees of True, C. H., and Brandt, C. H. W.). March 24, 1917, [Convention date]. Tubes.-An incomplete bend, Figs. 2, 3, formed from two tubes by the process described in Specifications 6304/15 and 100,223 is completed by first applying external pressure in the region of the points 1 to bring the open end to circular form as in Fig. 5, and then closing by swaging. The swaging is preferably performed by dies 3, 4 which are rotated and at the same time alternately opened and closed, the heated end of the bend being fed axially into the dies. An axial opening 5 is provided to receive excess metal, forming a solid projection 6 which may afterwards be removed. The bulges 7 in the bend may be removed by pressure in dies adapted to give the finished bend any desired form.
