Abstract
121,352. Rudge-Whitworth, Ltd., and Pugh, J. V. Dec. 14, 1917. Tubes. - Metal tubes are trapped or closed at the ends, particularly for forming connexions in tubular structures, so that the closed end is not greater than the original diameter of the tube. The tube end is compressed at a, Fig. 1, to figure of eight form, and is then flattened by pressure at b to the form shown in Fig. 3. Modifications are described in which the closed ends are of flattened U-, S-, and other form. A modification is described wherein the tube is cut at a before flattening so that two flattened portions c, d, Fig. 2, are formed. A tubular liner may, if desired, be inserted in the end of the tube before the trapping process is performed. The tube-end may be brought to the form of a square with rounded corners as a preliminary step to forming the figure of eight, and circular rods may be inserted to preserve the internal form during compression at a,
