.My .invention relatesto a new and improvedradiator construction,` and this case .is a diiision from mzy co-pending applicaftion, Serial No. 493,544,"led May '3rd, 1909.

The main object of the invention relates to improved structural features whereby a radiator may be produced at a mlnimumof withoutsacrifice-to strength or durability.

Afx'diator, as constructed,` will befound to beef particularntility when employed .in

, connection with'fwatercooling systems fon eoolin internal` combustion engines.

Slifphf thin met'el of suitalilolength and ation, this maehinemanipulates a strip -of :metal step by step, as indicated in -Fig. 4, wherein. a slight U- shaped bend, as shown at the left of said figure, is-formed. The next y .51 bend to the'igbt is Veghapedwhile the next bend tothe right, though"`.V-shaped,`is

' ysharper than the lforiner. When the metal. is Vin this condition, the walls of the sha-rp.

Vl-shaped bend are pressed tightlytog'ethr to form a closed plait, as shown by the'ffour finished Vplaitsat the right hand end of Fig. '4. The impprtan'ce of'closing the plaits .will later befsx lained. Not only is the :metal plaited, as reviously described, butf at" a suitable stage -in 'the .'"forming 'of thef plaitsthe edgesof lthe metal .at bo'th Ved es of the'sheetare offset. This will be seen y i referring to. Figs,

be found.

eliminating thel necessit for separate sprslbetween thesevera 4units' and b 4 so structing the `units that integral .o sets 'profvided for efecting the spacing With- -mtitseparate spacers, a very,v substantialV aniountof material andweight is szwedQ-an'l of reat importance.

,l ,Y onforrning the ends of 'the 'linsorplaits to fill out' the ext-ra space' between the va j at the ends formed by'oflsetting the side jwalls Vovl the several units, said 'plaits reinforce saidV side walls completely to the ends', furnishing a maximum of durability, since there is no" chance for vibration that Wouldtend to` crush iny the offset edges of said units/ Again, by contouring the plaits as aforesaid, an efective soldered joint between each of thejplaitsand the ady 'jacent surface of the side wall against which the edge' of the plait bears is absolutely guaranteed, as would not be the case if the' plaits 'were notL thus contou-redyfor as isl well fknown, it is next to impossible to bridge any slibstantial gap with h`ot solder Where the article to be soldered is dipped into the molten metal, as in this case.
