BURLING It. ROGERS, OF BALTIMORE, MARYLAND.

RADIATOR CONSTRUCTION.

Application filed February 28, 1921.

To all whom it may concern:

Be it known that I, BURLING T1. Rooms, a citizen of the United States, residing at Baltimore. in the State of Maryland, have invented certain new and useful Improvements in Radiator Constructions; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to radiator construction.

Among the objects of my invention are To provide a radiator having large cooling surfaces which are provided without the use of a large amount of material.

To provide a radiator having the parts so constructed and arranged that the water to be cooled must follow a tortuous path and be entrained in suitable pockets at various locations during its passage through the radiator in order to provide a maximum of time for the radiation of the heat from the water.

To provide a radiator having but small resistance to the passage therethrough of the cooling medium.

In carrying out my invention I make use of the instrumentalities illustrated in the accompanying drawing, in which:

Figure 1 is a partial front view of aradiator constructed according to my invention and suitable for use on an automobile.

Fig. 2 is a perspective view of the tube used in the construction of my improved radiator.

Fig. 3 is a perspective view of a portion of one of the strips used in the construction of my improved radiator.

Fig. 4C is a central section through one of the elements of my improved radiator shown in Fig. 1, the section being taken in a plane parallel with the face of the drawing.

In the drawings: 7

5 represents the top header and .6 the bottom header of the radiator. These headers are each shaped as usual in the form of a hollow metallic box, the upper header 5 being provided as is usual with a pipe for the influx of water or other cooling medium thereto, and the lower header being provided Specification of Letters Patent.

Serial No. 448,351.

with a similar pipe for the ettlux of said medium therefrom. Neither of these pipes are illustrated. I

The bottom of the header 5 is provided with a plurality of spaced slots such as T and the top of the header 6 is provided with a plurality of spaced slots such as 8, the slots 7 and 8 being in alignment.

Each element of my improved radiator is composed of strips such as 9 and 10. These strips are each provided with a plurality of flat portions such as 11 alternating with a plurality of crimped portions 12. The tube 13 has the cylindrical body 14 and the ends 1515 swedged to fit within the crimped portions 12 when the latter are assembled together as shown in Fig. 1. The flat portions 11-11 of oppositely disposed elements are soldered together and the crimped portions 12-12 are soldered to the ends 15 of the tube 13. The ends 15-15 of the tube 13 are made of such lengths parallel to the axis of said tube that the inner edges of said ends will extend inwardly to about the ends of the crimped portions 16, which crimped portions are in substantial alignment with the flat portions 11-11.

The crimped portions 1616 are provided in order to provide an opening for the cooling medium to circulate and also in order to provide pockets in which the speed of the cooling medium will be slightly reduced and thereby provide more time for the radiation of heat therefrom.

The strips 9 and 10 are each provided with bent ends such as 17 and the latter are soldered to the headers 5 and 6 so that the end crimped portions 16 will be in substantial alignment with the slots 7 and 8.

Thus it will be seen that I provide a simple, cheap and effective radiator having but few parts.

While I have shown but one embodiment and application of my invention, yet it is to be understood that many changes may be made therein without departing from the spirit thereof.

The air circulates through the interior of the tube 13 and between the crimped portions 12 and 16 of adjacent elements.

I claim An element for a radiator comprising a pair of oppositely disposed strips, each strip having a plurality of fiat portions alternating with a plurality of crimped portions, orimped portions between said first named crimped portions and extending between said flat portions, and a. tube mounted between said first-named crimped portions having ends to fit said first-named crimped portions, said flat portions being soldered together at their ends and the ends of said 10 first named tube being soldered to said t-riniped portions.

In testimony whereof, I aflix my signature.
