Application filed May 24,

To all whom it may concern: 1

Be it known that 1, Greece A. Houseman, a citizen of the United States, residing at Shreveport, in the parish of Caddo and State of Louisiana, have invented a new and useful Radiator Core, of which the following is specification.

The device forming the subject 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. I

The invention aims to provide a radiator core, the constituent members of which may be made out of a continuous strip, tubes being formed, and each tubehaving an inter nal partition, :1 sinuous passage for the liquid being provided.

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

"With the above and other objects in view,

which will appear as the description procoeds, the invention. resides in the combina tion and arrangement of parts 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 inven tion, parts being broken away; Figure 2 is a transverse section; andFigure 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 being denoted by the numeral 1, the side member 1 being prolonged to form a side member 2, the side member 2being extended to form a side member The side member is bent and extended to fashion an shaped partition 4 merging into a side member 5 which, in its turn, is continued to constitute a side member overlapped upon the side member 3, the side member 3 being disposed opposite to the side member 1 and the side member 5 being disposed opposite to 1921. Serial no. 472,112.

. cated at 6, theside member 2 being bulged inwardly as at 8. These inwardly bulged portions 6 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, there results, between the banks of the tubes, a sinuous passage 11 through which the liquid to be cooled passes. The inwardly bulged portions 6 and 8 do not extend to the ends of the tubes, the ends of the tube being left plain, as shown at 9, so

that when one bank of tubes is placed. against another bank, the radiator core will be closed at its ends. Owing to the fact that the E-shaped partition or fin 4: is pro vided, a maximum conducting surface is af forded, 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 remaining stationary at any one place. In view of the fact that each bank of tubes is made of a single strip of metal, the bank may be of any desired extent, that is, there may be 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 immersed in a composition composed of soldering flux and hot solder, a thorough coating both inside an dout being the result, and the constituent banks of tubes being held together securely. The device affords a large amount of heating surface with the expenditure of aminimuln amount of material, and a repair of the structure maybe brought about at any time without difficulty.

I claim 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 connecting spaced portions of the tube and located within the tube, the partition being reversely curved to give the partition an shape in cross section and to form longitudinal concavities in In testimony that I claim the foregoing as thepartition, opposed portions of the well my own, I have hereto aflixed my signature 10 of the tube being bulged inwardly, out of in the presence of two Witnesses.
