RADIATOR.

Specification of Letters Patent.

Patented May v23, 1911..

Application led May 19, 1910. Serial No. 562,225.

To all whom. 'it may co'lnzerfn:I

Be it known that I, JOHN M. FEnDERs, a

citizen ofthe United States, residing at' Buffalo in the county of Erie and State of New ork, have invented new and useful Im rovements in Radiators, of whichl the fol owingis af-gspeciication.

This invention relates to an automobile radiator and hasl or its object the production of a radiator' ofthis character which in my improved radiator. Fig. 2 is a fragmen webs, strips or ns. Fi

tary sectional perspective vlewrof one of the water tubes of my im roved radiator. F1g. 3l is"a similar view of) one of .the radiating 4 is a view similar to Fig. 2 showing a Slight modification of my invention. Flg. 5 is a fragmentary vertical transverse section of my improved radiator, o'n an enlarged scale. Figs. 6 and 7 are vertical sections in the correspondingly numbered lines in Fig. 5. Figs. l8 an 9 are horizontal sections in the correspondingly numbered lines in Fig. 5. Fig; 10 is a perspective view showing a modi ed form of the radiating webs o'r strips.-

' Similar letters of reference indicate corresponding. parts views. g In its general organization, my improved -ra'diatoreomprises an vupper" inlet header or manifold A, 'a lower. outlet header or `manifold B, two side pieces C connecting the opposite ends ofthe manifolds, a lurality of upright water tubes. D arrange in a transverse row between the side pieces and s each connected at its upper and lower ends with the upper and lower manifolds, ref" spectively, and a plurality of horizontal webs, strips or fins E arranged in vertical rtiers in Each ofthe water tubes 4is oblong-in cross section or elongated horizontally from the to the rear side ofthe radiator, so that lthe water' passes through the same in Athe form-,pf a thin film, thereby causing the heat in the same `to/be radiatedmore rapidly. Each waterktube is, preferably constructed of two upright sheet metal plates throughout the severalA the spaces between the tubes: a

or walls d, d which are provided on their opposing inner sides at their vertical edges, and at intervals between the edges, with ribs or beads e, e1, e2. The front and rear ribs e, e2 are secured to each other by'soldering so as to complete the tube and seal the same, while the 'intermediate beads e1 only bear against each other and keep the central parts of thetube walls from collapsing or being pressed an undue extent toward each other, thereby preserving the shape of the tube. The vertical front edges of the tube walls may be' provided withlaterally projecting upright flan es f, f, as I shown, for the purpose of sti ening these edges of the walls and also for givlng the same ya heavier appearance, as shown in Fig. 2. If desired, however, the front edges of the tube walls. may be left/ untlanged,.as shown in Fig. 4:.,

' The radiating webs, strips or fins between adjacent water tubes are spaced apart vertically a distance equal to the distance between 'adjacent water tubes, thereby divid.

ing this space into a plurality lof horizontal air passages which extend fore and aft and each of which is `square in cross section. Each of'these webs may be secured to the adjacent outer sides of the tube walls in various ways but preferably by roviding these walls between their beads with a plurality 4of pairs of horizontal longitudinalA ribs or beads g` which project outwardly. A-

seat for the adjacent longitudinal edge of one of the webs is formed between each'pair p of beads g. l-

v The front and rearl ends of the webs are preferably flush lwith the front and rear edges of the tubes for producing a finished appearance. Each web is provided on each of itsl longitudinal `edges with alternate salient and receding portions or faces k,- hl, Y

as shown in Fig. 3. The salient portion h ofthe webs it into the outerv sides of the.

inwardly bent beads'ia-el; e'2 of the tubes and tubes between thebeads thereof. The webs and ktubes are preferably secured to each -therecedin portions'lz.1 fit into the groves` which are ormed on the outer sides of the and also increasing the soldering area each longitudinal edge of a web is provided with avertical lange. As shown 1n Fis. 3, 5, 6, 8 and 9,-v this iiange is constructe in secf /H tions h2 one of which is arranged adjacent to each receding edge ortion of the web and secured in the seat o the tube between the adjacent beads g.

If desired the web El maybe provided with straight longitudinal edges and continuous attaching and stiifeninganges ns,

as shown in Fig. 10.

By providing ribs or beads on the tubes for the reception of the longitudinal edges of the webs, the parts can be assembled more easily and the structure as a whole` is rendered much stronger.

- The upper ends ofl the water ject upwardly through openings in the bottom or tube sheet of the upper header `or manifold and the lower ends of these tubes project downwardly through openings in the top or tube sheet of the lower header or ,manifold, so that these tubes establish communication between these headers. Al-

' though the Hue sheet of the upper and lower headers may be constructed in various ways, each of these sheets ispreferably built up of a plurality of sections i each of which is constructed substantially like one of the radiating webs E and also secured to the tubes in like manner by soldering each longitudinal edge of a tube sheet section in a .seat formed at the end of a tube between a pair of outwardly projecting beads g arranged on the outer side of a wall of the Owing to the fact that no water comes in contact with the radiating webs, the same may be made of tin or other cheap metal,

thereby confining the use of copper, brass or other: more expensive non-corroding metal to the water tubes and effecting a corresponding saving in the cost of manufacture.

I claim as my invention:

I 7 l. A radiator comprising an inlet header,

on its front edge with longitudina tubes pro# an outlet header, a plurality of water Atubes connecting the headers and provided on their outer sides with a plurality of pairs of outwardly projecting beads forming a seat between each pair of beads, and a plurality of radiating webs arranged in the spaces between the tubes and each provided at its 0pposite lon 'tudinal edges with flanges which are secure in the seats of said tubes.

3. A radiator comprising an inlet header, an outlet header, a plurality of water tubes connecting the headers and each rovided flanges projecting laterally in opposite directions, and radiating webs arranged in the spaces etween the tubes and each provided with langes on its longitudinal edges which stop short of the front end of the web and are secured to the outer sides of the adjacent tubes while the front end of the web is unlanged at its longitudinal edges and lits be tween the corres onding flanges at the front edges of the adjacent water tubes so as to be flush therewith.

4. A radiator comprising an inlet header,

an outlet header, tubes connecting said headers and provided with inwardly indented beads, and radiating webs arranged between the tubes and each provided on its opposite longitudinal edges with salient and receding portions which lit the outer sides of the beads on the tubes and the parts of the tubes between said beads, respectively.

5. A radiator comprising an inlet header,

an outlet header, tubes connecting said headers and provided with inwardly 'indented beads and radiating webs arranged between the tubes and each provided on its opposite longitudinal edges with salient and receding portions which fit the outer sides of the beads on the tubes and the parts'of the tubes between said beads respectively7 and said webs being provided on their receding edge portions with flange sections which are secured to the adjacent outer parts of the tubes.

Witness my hand this 17th day of May,

JOHN M. FEDDERS.j
