Abstract
292,507. Bundy, H. W. June 20 1927, [Convention date]. Tubes.-A tube with a spiral fin useful for the transference of heat, e.g. in mechanical refrigeration devices, automobile radiators &c. is formed from strip stock, Fig. 1, which may be previously tinned or which may be drawn through an acid bath 2, a solder bath 3, and a cooling water bath 5. The stock 1 is then drawn over a'guide roller 6, and between rolls 7, 8, Figs. 1 and 8, which gives it an angular configuration, after which it is coiled on a spinning arbor 12, the fin portion being crimped by co-operating rolls 15, 16. Rollers such as 20, 20<b> in the form of spirals then shape the tube, as shown in Fig. 3. Acid is then supplied by a spray 22, and the tube given a coating of solder from a bath 24, excess being blown off by a nozzle 26. The tube is cooled by a bath 27 and then passes through rollers 28 which serve to draw the tube along. The convolutions may overlap, as shown, to form a double-walled tube, or may overlap just sufficiently to secure them together.
