TO (all whom it may concern:

Be it known that I, Animus P. AnnunsEN, a citizen ofthe United States, residing of the honeycomb type, the primary objectbeing to provide a construction embodying simplicity in fabricationand. possessing great cooling facilities;

An equally important ob ect resides in the formation of the radiator units from a strip or sheet of material which is shaped and cut in a single operation and from which the several lengths forming the units are severed, the length of each section varying according to the size of radiator to be constructed.

The invention further resides in the features of construction hereinafter described and claimed, reference being made to the accompanying drawing wherein- Figure 1 is a fragmentary perspective view of a radiator water element con-' structed in accordance with the present invention;

Figure 2 is a similar view of the sheet from which the radiator is fabricated, viewin the sheet from the spacing end; and

*igure 3 is a perspective view of the sheet from the opposite end.

Referring more in detail to the accompanying drawing, the sheet 1 of light metal,

preferably light brass, and of. a suitable width and length, the latter being sufficient to produce several units, is'.passed through dies to cutandform the entire length into the configuration depicted in Figures 2 and 3, producing the corrugations with the raised solid webs 2 atone end and similar webs 3 at the opposite end. The webs'3 are slitted lengthwise of the sheet and, in the same die-cutting and shaping operation, the outer portions are shaped in the opposite direction to produce the spaci'ngwebs 4 which are reinforced bythe strengthening ribs 5. Each of the webs constitutes onehalf of a hexagon having a pair of vertical sides and pairs of upper and lower inclined or converging sides, the ribs 5 occurring in one of the inclined sides so as to leave Specification of Letters latent.

the yerti'cal uninterrupted iwhereby they mayv t c'al sides .of adjacent webs.

assembling the sections into which the orlginal sheet is divided,the adjacentjsec itions are reversed to bring the spacing webs f .ofonesection opposed to; the :webs 2 of the next adgacent section, thereby providing a spacing web at each side and the front and back of theQ ig-zag ywater'course I v solid contact with the; ver

6 as defined. by two fassembled sections. a Thus, when two sections are in assembled relation, the web portions. 7 will engage the web portions 8. and theweb portions 9 will engage the web portions 10- thereby definng the. vertical, Zig-zag watervpassage 6.

When two water courses; are assembled the web portionskllof the spacing webs will engage the n reb; portions {10, outwardly of and ontheoppos te side of the pointof contact between "the web portions 9 and 1(). Thus, the solid web portion 10, while 1 engaged only by auhalf-width web portion on one side in the make-up of a water course, is reinforced throughout the re m'ainder of its width by. the outwardly dis-" Y posed, half-width web portion when the watercourses are assembled; I

1th a sultable number of the sheets or sections assembled, they are held together in a form and dipped in solder to a depth sufiicient to secure the parts firmly together.

The depth to which the sections are dipped" n solder is indicated at.12 in Figure 1.

The construction of the radiator is extremely simple since the, originalfsheet may practically be of any length, in fact of such a length as to form all the elements of the Y radiator. The structure forms a very heat honeycomb type and by reason of the spacving webs 4 large zig-zag air spaces'or openings are formed so that the radiator has great cooling facilities. Having thus described my invention, what I claim as new and desire to secure by L t. ters Patent is v s:

1. A radiator comp-rising zig-z'ag water and air courses each water course defined by two nesting sheets of metal corrugated and having raised webs at each slde to space the intermediate portions of the sheets, the web) at one side only of each sheet and at relatively opposite: sides being slitted atintervals lengthwise of the sheet and the outer portions of the slittedweb being pressed in the opposite direction to form spacing webs for the adjacent Water courses on both sides.

2. A radiatorcomprising a plurality of section corrugations, saidflat sides of the spacing ribs adapted for seating against the outer faces of the uninterrupted webs of an adjacent section. i

3. In a radiator, a plurality'oii Zigzag Water courses each definedby a pair of correspondingly shaped sections of sheet metal having ofiset Webs uniting the pair of sec- 1 tions along their edges, port-ions of the Webs along the opposite edges of each course be? ing struck out in an opposite direction only to form spacing Webs for spacing adjacent courses at the front and rear edges of the Water course. I i

' 4. A radiator comprising a plurality of Zig'aag'Water courses, each formed of a pair of metal sheets having abutting ofiset edge webs at each side, portions of one eb only of each sheet being correspondingly stamped out in the opposite direction away from the Water course to form a hexagon "With the opposed portions of the Web from TWillCil said first portions Were formed, the

stamped web of one sheet being on the opposite side of the Water course andyattheopposite edge thereof to the corresponding Web of the companion sheet.

5. In a radiator, a length of sheet metal. bent back and forth to form relatively offset, parallel portions joined by inclined sides the edges of the length being offset to form webs and one of the Webs being lengthwise slitted at intervals to divide the Web into inner and outer series of Web sections, one series being pressed in the reverse direction to form portions parallel with theaforesa-id parallel portions and jo'ined'tothe other sev rles of Web sections by inclined sides certain of the latter being provided With strengtheningribs. i f i In testimony whereof I have signed iny name to this specification in the presence of two subscribing Witnesses.
