RADIATOR FOR AUTOIVZOBILES.

' Application filed May 5,

T uZZ-wizom it may concern:

Be it known that I, lVILLIs BYRON Conn-xiv, acitizen of the United States, residing at Colorado Springs, inthe county of El Paso and State of Colorado, have invented a new. and Improved Radiator for Automobiles, of which the followingis a specification. H

One object of iny invention is to provide 1 a radiator for automobiles ciances of bursting by freezing are minimized. A second object of my invention is to haveallsoldered joints exposed enter orly so that should the radiator, from any cause, spring a leak the seams may-be accessible-for mending without tearing the radiator to pieces to expose the leaks.

I attain these objects bythe mechanism illustrated in the accompanying drawings,

in which- Fig. l is a diagrammatic elevation of the front of the radiator. Fig. 2 is an elevation of one of the spiral fins shown in Figs. 3 and 5. Fig. 3 is detailed elevation oi part of the radiator showing some of the spiral fins, shown in Fig. 2, inserted. Fig. l is a perspective of a part of one of theair tubes shown in Fig. and shown in detail in 5. Fig. 5 is a perspecti e in detail of one or".

the air tubes shown in Fig. 8 and in Fig. T

on the line 8 8. Fig. 6 is a sectional eleva tion of T on thelineS-S. Fig. 7 is detail front elevation of part of the radiator shown in Fig. 1. 8 is a perspective detail of part of an air tube 1, and part of the face plate 3. I

Similar numerals refer to similar parts throughout the several views.

The air tubes 1, 1 passing from front to rear of the radiator, the spiral fins 2, 2 lo-' cated in the said air tubes, the'front' raceplate 3, the rear face-plate i and the enclosing radiator shell member 7 constitute the principal parts and framework of the said radiator. The body oi the tube 1 is adapted to fit the perforation 12 in the face plates 3 and at. The flange 6 on the tube 1 is adapted to lie upon the exterior edge of the. perforation 12 and is soldered the oint 5. lhe flange 11 on the said face-plate is adapted to be soldered .to the side-plates 10 of the radiator shell 7. The horizontal expandible connecting ribs 8 and the upright expandible connecting ribs 9 of the face-plates 3 wherein the and t admit of expansion of 1919. Serial No. 294,912.

the said faceplates adapted toequalthe e21 I pansion of the water in theradiator when. ireezing as shown by the convex surfaces of saidribs, which.in their aggregate form the I face plates, at 9- in Fi 2,.and at 8 in Fig,

4, showingthe curved einbossedlribs susceptible of expansion. The flattenedtubes l;

. admit of a great degree-ofcompression and are therefore adapted to relieve. strains in other dlrect ons. The sp1ral fins 2, 2- are placed in the air tubes 1, 1 to transmit heat from the walls of the said air tubes, andarel and are flanged as shown at G, 6, outside of the face "plates and are soldelred between the said langes and the outs de"oi the face plates. Ittvil'l be noted that thereareno internal seams, that all joints 5, 13 areex ternal and accessible for mending.

-..ving described. my. invention, what I claim and desire to secure by Letters Patent is: j

1. In a radiator of the class described, a combination of front and rear exp-audible face-plates, a plurality of flattened compressible air tubes secured to and extending thru both upright and horizontal corrugations'in said race plates, and spirally "formed fiat line extending through said air tubes.

2. Y In an automobile radiator of the class described, provided to withstand freezing and heating, the combination of a front plate and a back plate, having registering holes injthe two said plates provided to receive the ends of connecting air-tubes, fiattcned compressible air tubes passing through said holes and connecting said' plates, impressed embossed ribs in said plates extending uprightly and transversely acros's said plates between the termini of said tubes, and provided to allow the expansion of said plates by frost without bursting the plates, outwardly turned flanges on the ends of said tubes provided to form a tight head-for aid holes and to form a recess for solder, spirally it'orined flat fins extend: ing through said'tubes and attached to the sides thereof and provided to transmit the heat of the tubes to the atmosphere.

said. face-plates andat an angle thereto 3. An automobile radiator comprising a face plate and a back plate of the same size and provided with an equal number of registering elongated slot holes, a multiplicity extending across said plates in transverse directions between saidtubes and provided to allow the expansion of said plates without rupture, and spirally formed fiat fin members extending through said tubes and provided to transmit heat from said tubes to the engaging air. Y

4. In an automobile radiator of the class described, the combination of 'a face plate and a back plate, an enclosing shell member tightly secured atits enclasping edges to the edges of said plates and forming a chamber between them, a multiplicity of flattened seamless tubes passing through both of said plates and uniting them, outwardly projecting turned flanges on the ends of the tubes engaging said plates and forma ing a head'and a recess for solder, deeply impressed curved embossed ribs extending across said plates in transverse directions between said tubes and provided to allow the expansion of said plates without rupture,

and spirally formed fiat'fin members extending through said tubes and provided to transmit heat from said tubes to the passing air.

5. In an automobile radiator of the class them, a multiplicity of flattened seamless tubes of metal extending through registerspira'lly twisted flat fin members extending through said tubes and provided to engage the cooling air to conduct the heat from said tubes, outwardly extended flange members 'ing holes in said plates, a multiplicity of formed on the ends of the tubes and forced against the outer surfaces of said plates and Y forming a recess for solder, and a multiplicity of impressed embossed ribs in said plates and extending in transverse directions to each other between said tubes and provided to allow for expansion without a rupture.
