RADIATOR.

Application led June 21,

My invention relates to radiators and has among its other objects the production of Vdevices of the kind described which are convenient, durable, etlicient and satisfactory for use wherever found applicable.

A particular object of the invention is to provide anv improved device of thekind described comprising sheet metal stampings which can be quickly and easily assembled with each other. e .i Another particular object of the invention is to provide a radiator for an automobile or the like having improved means for causing the air passing through the radiator to come into Contact Awith all portions of the water tubes thereof. v

rMany other objects and advantages of the construction herein shown and will be obvious f to those skilled in the art from the disclosure herein given. To this end my invention consists in the novel construction,arrangement and combination of parts herein shown and described, and` morey particularly pointed outin the claims. i

.In the drawings, whereinV like reference l characters indicate like or corresponding lparts:` Y

Fig. 1 is a fragmentary front elevation, 'partly in section, of van automobile radiator embodying the invention;

Referring for the presentto Figs. 1 to 5, Y

inclusive, wherein I `have shown'onefform of the inventionV embodied in an automobile radiator designated generally by the reference character 1Q, the' reference characters 12 and 13 designate the upper and lower tanks, respectively, of the radiator.

tanks 1,2v and 13 communicate with "each Awhich are preferably formed from relative- 1y thin sheetmetal and are preferablyl yot' described The 1,926. Serial No. 117,252.

elongated cross section, as best shown in Figs. 2 and 3. The tubes 14 are preferably formed with a seam 16 extending longitudinally of one edge thereof, the seam 1,6 being i the central'portion of the tube.` This aids in the exchange of heat from t-he water t'o the air flowing through the radiator. ,The longitudinal edges are preferably arcuate as at 18, one arcuate edge 18 having the seam* 16 formed therein. v 'lfheseamv 16 preferably projects outwardly from the tube so that it may be quickly and easily soldered, or re-k solderedif'it becomes damaged in use".`

The upper and lower ends of the tubes 14 preferably' project tln'cugh header plates 19 and are preferably, soldered thereto, the

plates being soldered or otherwise secured to the tanks 12 and 13. However, it is readily understood that in someinstances I may prefer to dispense with the header platesb 19 `and solder the tubes 14 directly 'to they tanks 12 and 13.

Associated.l with the tubes 14 and prefera.

bly soldered thereto are aplurality of cooliing fins 22 which in this embodiment of the l invention are stamped from relatively thin l, thereto, each iiny being soldered to onek vof the pair of fins soldered vto an adjacent tube 14.

in the same plane, and a plurality of spaced portions 25 disposed ,in a substantially paralflel plane. The portions 25 are disposedl intermediate the .portions 24 and arejoinedl thereto vby,.inclincdportions 26.. Formedy 1n each portion 24 is a relatively large depression 28 .adapted to` accommodate one-half of the circumference of one of the tubes 14,

I Each of the 22 comprises4 a plurality of spaced portions24 disposed substantially .a smaller depression 29 forming an extension f.

- onehalf of the seamy 16. The depressions other through a plurality vof water tubes 14 i' 28 and 29 are best shown in Figs. 3V and 5,A Fig. 5 being view of one of the fins 22 look# i at the side thereof in vwhich therdepresv inthe portions is formed into ribs 35.

sions are formed. Rows of hollow buttons or projections 31 are preferably stamped in the portions 24 and 25 to facilitate the task of aligning the fins with each other during theassemblyof the radiator, theconstruci tion being such that the projections formed upon one fin will extend into in the projections formed upon the other fin (See Fig.`

3). However, it is to be understood that in the preferred embodiment of the in-vention the fins are identical in construction and it is only necessary to reverse oneof the fins with respect .to another when it is desired tohave the projections of one extend into the projections of the other. p

"Formed in the portions 25 are deflecting portions 33 which are adapted to guide air `passing through the radiator so that the air fiows aroundthe rear edges of the tubes 14 l(see Fig. 2). This insures. that there will bean efficient exchange ofheat through the rear` edges of the tubes 14 and the air Jpassing through .the radiator. The surplus metal .which also VContact Awith airpassing through thelradiatorand aid 'in the exchange of heat between the water tubes and the air.V In y the preferredrembodiments of the invention the fins 22 Vare soldered to each other and to the tubes 14- so that the assembled struc- V ture is relatively rigid.

Y In Fig. 6 I have shown another form of the invention einbodiedin radiator construction wherein a row of front water tubes V40 dered atanytime should they need repair- Soldered to the tubes 40 .and 41 are a ing.

plurality -of cooling fins which vresemble the aforementioned cooling fins 22 in structure but differ therefrom by being provided with both frOIlt'and rear depressions 47, for accommodating the front and reartubes 40 Eand 41, respectively. vThe cooling fins 45 falso differ in `construction from thefins 22 vby. being provided with two rowsof deflecting portions 49 in place of the deflecting portions 33 provided in .the fins 22, v`The front deflecting portions 49 insure that air passing through the radiatorwill be brought intointimate contact with the rear edges of ythe ,front .tubesj40vandthe rear defleoting `portioiis49 insure that the air will come in yContact ywith the rearwardly disposed edges `of vthe-reartubes 41. With the .eX- ceptions noted, the fins 45 are substantially identical with the fins 22 and may be assembled with the tubes 40 and 41 in substantially the saine mannery as the fins 22 are assembled with the tubes 14.'

Having thus described 1my invention, it is obvious that various immateriall modifications may be made in the same without departing from the spirit of my invention; hence I dov not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.
