Abstract
17,085. Maquet, C. Aug. 8. Metal tubes.-Consists primarily in the manufacture of heat-radiators consisting of metal tubes carrying a series of thin metal gills. For fixing the gills without soldering or brazing, each gill g, stamped out of sheet metal, is, after its central aperture has been burred out, threaded upon the tube a, Fig. 1, supported on a mandrel. The burr is then forced back into the plane of the ring by means of the mandrel A, and the gill thus secured to the tube by gripping. Between each gill the stay b and the scissor-shaped anvil d is placed. The process may be reversed, as shown in Fig. 5, and a mandrel with a coned head B employed for expanding the tube and fixing the gills. The head B may be replaced by an inclined ring which turns on its axis like a screw ; the ring, .however, may be perpendicular to the axis of the mandrel.
