RADIATOR CONSTRUCTION. I

Application filed September 25, '1925. Serial No. 58,539.

My invention relates to radiators and particularly to radiators" suitable for use in automobiles, aeroplanes and the like. The invention has among its other objects the produc- 'tion of devices of the kindv described which In the' drawings, wherein like reference.

' characters indicate like or corresponding parts; Figs. 1, 2 .and 3.are fragmentary views in elevation of a plate adapted to form parts of a radiator embodying the invention, the plate being shown in varlous stages-of manufacture;

Fig.

Fig. 5 is a fragmentary section" taken th-rough'a radiator embodying the invention; Fig. 6 is a' section taken on line.66 of Fig.5;and

FFig. 7 is asection taken on line 77 of ig. 5. As illustrated in Figs. 5, 6, and 7, a preferred form of the invention is embodied .in a radiator comprising a plurality of tubes 10 and plates 11, the tubes 10 being passed through apertures 13 in the plates. The tubes 10 are preferably formed from flat sheets of metala-nd are preferably of elongated cross-section, the front and rear edges of the tubes being rounded, the side edges of is a section taken on line H f the sheets being brought together to form.

lap seams 10.- I

In Figs. 1, 2 and 3, I have illustrated a 5 method whereby I preferably form the apertures 13 in the plates 11. Thus, in Fig. 1 I have shown the plate 11 provided with a plurality. of slits 15 extending transversely of the plate, the slits 15 being punched or stamped in the late by any suitable a pa- ;ratus (not shown After the slits have heen formed in the plate 11, those portions of. the

plates disposed intermediate thefslits are stamped or formed into elongated arcuate bulges 17 which are Fig 6 and 7.

most clearly shown in 'No. 58,542, filed Septem from the spirit of This draws the v1 5 into pointed ended slots 19 which are-illustrated in Fig. 2. The ends of each slot 19 are then rounded, as illustrated in Fig. 3,.to correspond to the rounded ends of the tubes 10, the material at the ends of the slots 19 being upset to provide 'arcuate flanges 21 adapted tocngage the tubes 10.

After the tubes 10 have been inserted in the apertures 13 .of the plates ll they are preferably soldered to the plates by practising the improved method more full described in my ,copendin application, erial er 25, 1925. Briefly each plate 11 is preferably coated with any suitable substance to which solder does-not readily adhere. This may be done before or after the apertures 13 are formed in the plates, but preferably before, so that the edges of the slots'13 and the inner surfaces of the 'arcuate flanges 21-will present clean surfaces to the tubes. ,If the coatings are applied to the plates after the slots 13 are formed therein, the edges of the-slots 13 and the. in-

ner surfaces of the arcuateflanges 21 may be cleaned by brushing them. A ter the tubes and then dipped a short distance into a'bath of fused solder, whereupon the solder rises along the tubes at those points where the plates 11 nor does it tend to spread itself over I those surfaces of the tubes disposed inter mediate the plates 11, except that the lap seams are soldered during one dipping operation.

Having thus described my invention, it 'is 18 held in substantially horizontal position,-

plates will be properly a and plates have been assembled, the radiator obvious that various immaterial modifications may be made in the samewithout departing my invention; hence I do not wish to be understood as limiting myself tothe exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.-

What I claimas new anddesire to secure by Letters Patent .is:' e

A method cramm ng a radiat r com ri ing a plurality of plates and substantially the tubes by io rmingthe excess material into fiat sided tubes passed through apertures in flanges at thecnds of the aperture and into 10 said plates, which method comprises formbulges adjacent the aperture, and inserting ling a plurality of substantially straight slits said tubes through the apertures in the in the plates While they are fiat in such manplates. t ner that substantially all of the material is In testimony whereof, I have hereunto left in the plates, .forming each of said slits signed my. name.
