To all whom it may concern:

Be it knownthat I, GEoRo-E'A. HOUSEMAN, a citizen of the United States, and a resident of Shreveport, in the parish of Caddo and State of Louisiana, have invented certain new and useful Improvements in Radiator Cores; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. I

The device forming thesubject matter of this application is adapted to be employed for cooling, heating or condensing, the structure being of peculiar utility when embodied in the form of a core for the radiator of an automobile.

The invention aims to provide a cellular radiator core, the constituent members of which may be made out of a continuous strip, tubes being formed, and each tube having an internal partition, a sinuous passage for the liquid being provided.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

\Vith the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of arts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in perspective, a device constructed in accordance with the invention, parts being broken away.

Figure 2 is a transverse section.

Figure 3 is a side elevation, the line 2-2 in Figure 3 indicating the cutting plane on which Figure 2 is taken.

In putting the present invention into practice, a strip of metal is provided, and the same is bent upon itself to form the outer wall of a tube, one side member of the tube bein denoted by the numeral 1, the side mem r 1 being prolon ed to form a side member 2, the side mem r 2 being extended to form a side member 3. The side member 3 is bent and extended to fashion an S-shaped-partition 4 merging into aside member 5, which, in'its turn, is continued to constitute a side member 10 overlapped upon the side member 3, "the side member 3 being disposed opposite to the side member 1 an the side member 5 being disposed opposite to the side member 2, as shown clearly in Figure 1 of the drawin s. The side member 10 ofany one tube orms the member 1 of the tube next adjacent thereto, the construction being continued to any desired extent, so that each bank of tubes is formed from a single strip. 1

Referring to Figure 2 and comparing that figure with Figure 1, it will be noted that the vertical side member 5 is bulged in- \vardly to form a channel as indicated at 6', and the vertical side member 2 is bulged inwardly to provide a channel as indicated at 8. These inwardly bulged portions or channels (3 and 8 are not located opposite to each other, and, consequently, when one bank of tubes is placed against another bank, as shown in Figure 2, theinwardly bulged portim' or channel 6 of each tube stands opposue to and complements the noninwardly bulged portion or rib of the adjacent tube in the same horizontal row, so that there results, between each of the vertical banks or rows of the tubes, a sinuous pass.(ge 11 through which the liquid to be coole passes. The inwardly bulged portions 6 and 8*do not extend to the ends of the tubes, the ends of the tubes being left plain, as shown at 9, so that when one vertical bank of tubes is placed against another bank in assembling the cellular radiator core, the liquid .or water passa between said banks will be closed at its en 5. Owing to the fact that the S-shaped artition or fin is provided, a maximum con ucting surface is afforded, and the tube, at the same time, is reinforced and strengthened. The sinuous passage shown at 11 promotes the operation of the device, in that no eddies result; no large body of liquid remains stationaryat any one place; and, sincethe water is forced to follow the sinuous path of said passa e and has no direct, straight path theret irough, the flow of the stream through the sinuous passage brings substantially all the water or liquid into frequent and continuing contact with the metal walls of the passa e, thus insuring a rapid temperature interc ange and a quick loss of heat through cavities in the partition, of the wall of the tube being bulged the radiation of the metal of the core. In

view of the fact that each bank of tubes is made of a single stri of metal, the bank may be of any desire extent,that is, there may as many or as few tubes therein as the manufacturer may desire. After any desired number of banks of tubes have been assembled as shown in Figure 1, the same are immersel in a composition com osed of solderin flux and hot solder, a tlorough coatin oth inside'and out being the result, and t e constituent banks of tubes being held together securely, The device affords a large amount of heating surface with the expenditure of a minimum amount of mate rial, and a repair of the structure may be brou ht about at any time without difliculty. I fiaim as my invention 1. A radiator unit embodying a tube fashioned from a single strip bent upon itself to form, in a one piece structure, the outer wall of the tube and a partition connectin spaced ortions of the tube and \locat within t e tube, the curved'to give the cross section and to form longitudinal conopposed portions inwardly, out of alinement with each other, in spaced relation to the ends of the tube and in alinement with the concavities' of the partition, to form, in the completed radiae tor a sinuous water passage.

2. A cellular radiator core comprising a plurality of tubular members, said tubular members being substantially rectangular in cross section and being arranged'in vertical partition bein" reversely' partition an shape inand horizontal rows, the several tubular members having their opposed, vertical side wallsintermediate their ends formed to provide lon itudinally extending complemental ribs an channels whereby vertically dissed passageways are provided between adacent vertical rows of tubular members, and each tubularmember being provided'intermediate said side walls with a longitudinally extending fin S-shaped in cross section connecting its top and bottom walls.

3. A cellular radiator core com rising a plurality of tubular members, sai( tubular members being substantially rectangular in cross section and being arranged in vertical and horizontal rows, the several tubular members having their opposed side walls intermediate their ends formed to, provide complemental ribs and channels whereby vertically disposed passageways are provided intermediate said walls, and an intermediate,

S-shaped in cross section connecting the top \and bottom walls of each tubular member,

the several tubular members in each vertical row being fashioned from a single strip bent upon itse f, to form in one piece the tubular structure including said fin.

In testimony that I claim the foregoing as my invention, I aflix my signature in the resence of two witnesses, this 10th day of arch, A. D. 1923. r
