Abstract

480,513. Making gilled tubes. BERG, A. J., and HUSE, J. O. Aug. 18, 1936, No. 21696/37. Convention date, Feb. 14, 1936. Divided out of 480,440. [Classes 83 (ii) and 83 (iv)] [Also in Group XIII] Gills for heat-exchange tubes are made from a block 10 of metal partially divided by staggered cuts from opposite sides. The block is intermittently fed along a guide (not shown) to oppositely arranged radial cutters 13 on a rock-shaft 11. The cutters are arrested in the mid-position to allow the block to be fed. The cut block is axially expanded and secured to a heat-exchange tube.
