' RADIATOR FOR eirromoisrtns.
T 0 all whom it may concern:
Be it known that I, THOMAS J. Kmion, a:
citizen of the United States, residing at Toledo,-in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in, Radiators for Automobiles, of which I declare the following to be a full, clear, and exact description.
This invention relates to improvements in radiator cores, such as are employed in of radiators for automobiles. The principal object of this invention is to provide a radiator construction in which the cost of the metal employed can be reduced without lessenin the effective radiation. Another object o my invention is to provide a radiator construction, which operates very efliciently to cool the water of the en 'ne cooling system, and which can be pro need and assembled rapidly and conveniently in large quantities and at a low cost.
j of this specification, on whic Further objects and objects relating to economies of manufacture and details of construction will definitely appear from the detailed description to follow.
I accomplish the object of my invention in one instance by the devices and means described in the following specification but it is evident that the same may be varied widely without departing from the scope of the invention, as pointed out in the appended claims.
A' structure constituting a preferred embodiment of my invention is illustrated in the accompanying drawings, forming-a part Fig. I is a view in front elevation of a radiator embodying my invention.
Fig. II- ie a detail, fragmentary, sectional View taken substantially on the line II-II of Fig. III, showing a portion of a radiator core constructed in accordance with my invention.
Fig. III is a detail, fragmentary,'section alview, taken substantially on the line TIL-III of Fig. II.
F'ig. IV is a detail, fragmentary view in side elevation, of one of the water tubes.
Fig. V is a detail, perspective view showing one of the water tubes and a'spacer between the water tubeand the next adjacent water tube, and the connection of said tubes to the lower header.
Fig. V1 is a detail, perspective new, show-' Specification of Letters Patent.

ing the connection of the water tube up or header.
n the drawings, similar reference n'umerals refer to similar parts throughout the several views, and. the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.
to the Considering the numbered parts of the drawlngs, the radiator 10 comprises an upper header 11 and a lower header 12, which are connected by the flat elongated water tubes or passages 15. The headers 11 and 12 are open at the bottom and top respectlvely, and provided with the in-turned flanges 13 and 14, which engage the tops and bottoms of said water tubes respectively, and as said tubes or passages form the sole connections between the upper and lower headers 11 and 12, thewater of the engine cooling system which passes into the upper header l1, flows downwardly through the tubes 15 to the lower header. as it is forced through the system.
In order to provide an effective radiator, it is desirable that as large a radiation surface as possible should be provided which is exposed to the current of air passing through the radiator to cool the water contained in said tubes or passages. Each of said water tubes 15 comprises the end portions 16, which are pressed together and in which are located the joints of said tubes, said tubes being otherwise seamless and without joints or cracks, and each of said tubes isprovided at intervals with the laterally extending fins 17, which extend at right angles thereto and form hollow branches or arms, as clearly appears from Fig. II of the drawing. Intermediate the laterally extending arms or fins 17, grooves or depressions 18 .are provided in the side walls of the tubes 15, in order to increase the radiation surface thereof. These water tubes are assembled together relative to the upper and lower headers, with the flat end portions 19 of said laterally extending arms or fins 17 resting on the flanges l3 and 14: of the upper an lower headers respectively, and flat spacing strips 20 are interposed between each pair of tubes, with the edges of thelaterally extending arms or fins 17 engagin said sheets, as clearly appears from Figs. I and V of the drawings.
A These strips of metal 20 not only serve to space the .water tubes relative to each they ' the laterally extending arms or fins'on the water tubeand'take heat. therefrom, thus heating their surface which is'exposed tothe current of airpassing through the radiator. The distancebetween the pointsat which said sheets'20 en age the laterally extending fins'or arms 1? of the water tubes is such that they act as efficient radiation surfaces, since these points are close enough together so that heat is readily transferred by convection to the strip of metal, and at the same 'time, the strips will take up. as
much heat from the tubes as they can readily give up to the cooling air currents so that; .eflicient radiation is secured.
The strips of metal 20 do not need to'be made of the same material as the tubes 15,'.
but may be made of a cheaper or less expensive material since they 0 not come into contact with any water, and act merely as spacers and radiation surfaces; The ends of the tubes are dipped in solder, after the whole radiator core is assembled together, which serves to close the seams and joints at the ends thereof, and to fasten thetubes with relation to the spacing strips 20, and this also serves to seal the upper and'lower-headersand fasten the tubes relative thereto. Since there are no seams in said tubes, except at the ends thereof, it is only necessary to dip the ends thereof in solder and this means a consequent large saving in the amount of solder necessary in the manufacture of radiator core.
I am aware that the particular embodiment of my invention, which I have here shown and described, is susceptible of considerable variation, without departing from the spirit thereof, but I have found that this gparticular embodiment is desirable, and
therefore I desire to claim my invention both specifically and'broadly, as indicated by the appended claims.
Having thus described my invention, what I claim as new, andv desire to secure by Letters Patent, is
1. In a device of the character described,
ing therein, -a water tube unit connected therewith comprising a flat tubular portion,
and a plu ality-of hollow arms communicating thegewith and extending therefrom, the lower said header and spanning said opening.
0st of said "arms resting. upon 2. In a deyice'of the character described, 2 the combination of a header havingan opening therein, a plurality of water tube units in communication therewith, each of, said units comprising a flat tube having hollow arms, extending laterally from opposite sides thereof, a Separating plate between adjacent units, the'ends of the lowermost arms of said units andsaid plates being secured directly to said header and serving to close the opening therein. f I
3. In a device of the character described, the combination of an upper and a lower header, a water tube unit for connecting said headers comprising a flat tube having a plurality of laterally extending hollow arms communicating therewith, the uppermost and lowermost arms having. their walls pressed together at their end portions and secured to said headers.
. .41. In a device of the character described,
the combination of an upper and a lower header having opposed openings, i iplurality of water tube units each comprising a inglaterally from each side thereof, metal plates contacting with the outer ends; of said arms and separating adjacent units, the uppermostand lowermost arm of each series having its walls pressed together and secured to the adjacent header tov close the opening therein.-
5. In a device of the character described, the combination ofa header having an openi'ng therein, a water tube unit connected therewith comprising a fiat tubular portion and a plurality of hollow arms. communicating therewith and extending therefrom, certain of said arms engaging said-header and spanning said opening. 7
