Abstract

266,913. Karmazin, J. March 13, 1926. Radiators.-A flat strip of metal is stamped into shape and assembled to form water-cooled radiators for internal combustion engines. The strip 15 is drawn from a roll 40 under a roll 42 through a lubricating bath 41 and between dies 23 by feed rolls 54, 55 continuously driven from a pulley 21. The upper die carries tools 25 which flatten the strip, a series of tools 26 which form progressively staggered tubes 33, punches 27 perforating the bottoms of the tubes having wings 341 connected by a diametral bar 341<a>, punches 28 perforating holes forming air-circulating projections 35, and notching cutters 29 for trimming the edges of the strip. Spring ejectors 81 raise the strip from the bottom die plate. The die 23 carries projections which engage the notches made by the cutters 29 to arrest the strip at each operation. The lower feed roll 54 is grooved to allow of the passage of the tubes and the bottoms of the grooves are shaped to bend the wings 341 vertical. The elements are detached from the strip by a shear blade 621 reciprocated by an adjustable cam driven by worm gearing from the shaft 20. A stacking device comprises a framework 79 carrying a table 81 lowered by a screw 82 rotated from the shaft 20 and carrying a pin 91 actuating trip gear 92 throwing out a clutch and stopping the machine when the complete radiator has been assembled. The elements are forced together, between a plate 80 and the table, by hand actuation of the screw 82. As the strip used has a slight taper the punches in the two rows are of different lengths, the roll being held in either of the positions shown in Fig. 1 according to the manner in which the roll is wound. Specifications 201,934 and 270,609, [both in Class 64 (iii), Surface apparatus &c.], are referred to.
