forming an interior air passage by which the vertical water passage is divided, thus reducing the cross sectional area of the column of water by subdividing it, thereby enabling a rapid and eflicient cooling of the liquid.
Further, the invention resides in the salient features of construction and formation of the radiator core hereinafter described and claimed, reference being bad to the accompanying drawing wherein- Figure 1 is a fragmentary front elevation of the radiator core embodying the present invention Fig. 2 is a plan view of the blank from which the component parts of the radiator are formed;
Fig. 3 is a vertical section on line 38 of Fig. l;
Fig. 4 is a transverse section on line 44 of Fig. 5; and
Fig. 5 is a vertical section through Fig. a on line 5-5 further disclosing the construction.
Each core section of the radiator is constructed from a sheet of metal, such as brass, which has raised contact spots 1 along each edge alined with those along the opposite edge. The blank is then bent or folded upon itself transversely so that its ends will overlap for securement and the contact spots 1 will engage corresponding spots 011 the same edge of the blank to form closed seams at the front and back edges of the core sections 3. Intermediate the spots 1 or the alined seams is a vertical passage l establishing communication between the superposed and horizontal air passages 5. The area of these vertical passages may be varied as to size by increasing or decreasing the size of the spots 1 which will lengthen or shorten the closed seams.
Specification of Letters Patent.
Patented Feb. 28, 1922.
Serial No. 333,537.
In this connection it will be noted that the raised portions 1 are ovaloid, tapering to the edges of the blanl This area of contact between the folded portions of the blank permit the flaring of the ends of the horizontal air passages 5, as depicted in Fig. 4, the edges at the widest points of the flares being slightly raised for forming ribs, as at 6, to firmly seat on the flattened seams. Ordinarily the sections have solid contact with each other throughout the points of contact as indicated at 7 but by the improved construction this solid contact is materially lessened and in addition a vertical air passage is interposed so that the air in passing through the horizontal air passages can also flow vertically through the passages l-which are substantially axial of the duplex water channel at the points of contact. This added air passage materially adds to the cooling surface for the water which is carried through the serpentine vertical passages 8 from the top to the bottom boxes not here shown but which may be of the usual or conventional type.
Having thus described my invention, What I claim as new and desire to secure by Letters Patent is:
1. A radiator comprising core sections each formed from a sheet metal blank having ovaloid raised contact spots along its opposite edges, said blank being folded transversely to bring the contact spots together and thereby form closed seams and,
superposed horizontal air passages having communication with each other by means of a vertical air passage between the front and back closed seams said sections providing water passages therebetween.
2. A radiator comprising a plurality of sections defining water passages, each section formed from a sheet of metal having marginal o'valoid raised portions for seating on opposing ovaloid portions of the adjacent section to provide front and back closed seams with an interposed vertical air passage establishing communication between upper and lower horizontal air passages.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
