CHICAGO, ILLINOIS, CORPORATION 0F RADIATOR.

Application 'led May 16,

. To all 'whom t 'may concern:

Beit lmown that we, Louis FABER and PHILIP SCHNi-iininz, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have jointly invented certain new and usefiil"Improve ments in Radiators, of which the following is a specification.

This invention relates to a new and improved radiator, and more particularly'to a. radiator of the type particularly adapted for'use in connection with the cooling systems of internal combustion engines. In such radiators it is now customary to provide a' plurality of tortuous passages so formed as to present a large area for contact with thev air. The efficiency of the radiator is limited by the area'of exposed coolv ing surface and is further' limited by the facility with which -air may reach andpass over such ycooling surfaces.

In certain types fof radiator tively large varea of radiator construction in order to aliord adequate cooling area. In radiators, especially those adapted oriise upon motor vehicles, compactness is an essential feature.`

It is an 4object of the present invention to provide a radiator construction having a plurality of adjacent water pasages, these passages 'connected into a unitary structure `by separating means. the separating means, however, affording air passages adjacent all parts of the surface of the water cooling members.

It is an additional object provme adevicc'of this character in which two-separate air spaces are provided between eachuie fiattened water passages are formed with a number of 1921. Serial. N0. 489,774.

adjacent pair of water cooling members, one such space adjacent each member, the mein.A bers thus being kept out of contact with each other, and the spaces forminor continuous ai r passages bothI longitudinally and transversely.

It is also an object to provide a structure in which this is accomplished by means of a single s 'acing element placed between each pair of a 'acent water cooling elements.

It is a urther object to provide a device of the character described which is com pact and affords a maximum of radiation surface and which is composed of but few and -relatively simple parts and which mag .be manufactured at small cost.-

ther and further objects will appear as the description proceeds. j

Broadly, o ur invention comprises a series ofjuxtaposed water cooling members with a separator plate inter osed between each pair of such members. are laterally dis laced in opposite direc tions, and these ispla'ced portions are attached to the two adjacent water. cooling members. v The major portion of the sepa rator plateis., however, unattached to either such water cooling member, and preferably air passages extending both longitudinally and laterally of the surfaces ofthe water cooling members are provided between each such member and its adjacent separator plates, I'

We have illustrated a preferred embodiment of Vc'iuiinvention inthe accompanying drawing, in which- Figure Ii is a -general view ofthe radiator `structure according to our invention Y 'Y Figure- 2 is a fragmentary view on an enlarged scale showing a portion of the coi1- struction Y Figure 3 is a vertical transverse sectioi: taken on line .3-3 of Fig. 5;

Figure 4 illustrates a series of elements used in forming the radiator; and v Figure 5 is a section taken on line 5 5 of Fi re2.- y s shown in the drawings, the radiator is ortions of theplate formed of a plurality of corrugated plates 6, these plates having their edges? laterally ioo offset from the main body of the plate. Between each air of such plates 6 is located a separator p ate 8 having its edges 9 ollset in a manner generally similar to that ot' the plat`es 6. The offsets on the plate 6 as shown are`o`f such a type that when the plates are juxtaposed hexagonal cells are formed.

As sliown'Din Figure 3, when the edges of the several lates are brought together there is formed 'etween the adjacent plates 6 a channel W adapted to receive water. This channel has portions of alternately greater and less cross section due to the peculiar' configuration of the forming plates.

The spacing lates 8, as best shown in Figure 3, have t eir central or body portion entirel flat, their edges only being deforme or laterally displaced so as to be engaged by anvil attached to the adjacent water passage formin plates. The offset of the edges of the p ate 6 is such that, as best shown in Figure 3, these lates, although joined at the edges to the ates 8, are else- Where separated from sucn lates forming air passages A 4which' are a so of varying cross section as are the water passages. These air passages extend longitudinally of the radiator plates-that is, vertically as shown in Figure 3. Transverse air passages 13 through the radiator are falso formed between the lates.

The radiator may' e preferably manufac tured by plcingjagainst each other a pluralitj7 of sections as shown in Figure 4, in which "a water" tissage forming plate 6 'is placed upon eac side' of a spacing plate 8. The laterally displaced edge portions 10 of V.the plate 8 are alternately brought into contact with the adjacent portions of each of the two water passage formig plates 6.

It will be observed that l.these portions 10 have a depressed portion' 11 formed adjacent thereto. These depressions 11 are short and extend a relatively smallportion of the width of the plate, serving to receive the ends of the de ressed portions 12 of the water passa e' ibrming lates, these latter depressions eing best -s iown in Figure 3. The depressions 12, however, extend suhstantially thev full width of the plates 6, their ends being. pocketed in the depressions 11 upon opposite edges ofthe plate 8. The depressions 12 increase the areaiof the water passage and also by their seating in the' depressions 11' aid in maintaining the plates 6 and 8 in their proper relation both .laterally and longitudinally when handling the"pl'ates in forming thevradiators.

It will be observed that each element, as

shownin Figure 4, is provided with two vertically extending air `passages separated by the lplate 8. It is also provided with .transversely extending apertures 13..4 When two such elements are placed together, the water passage W is formed lief/veen tl-zvrn,

In forming the radiator-a plurality of elements as show-n in Figure 4, of proper length, is placed in a form or jig and the edges of the plates are dipped in molten solder in order to fully close the ends and maintain the plates in proper relation.

The completed radiator element then is placed in the radiator body 14 or has its upper and lower faces connected in any desired manner to radiator body members to form a water tight connection therewith.

Obviously the effective thickness of the water passages may-be varied by varying the amount of the offsets upon theedge of the plates; However', these offsets are limited by the nature of the material and the a cility with which it flows under formingV pressure.

The plates 6 and may be readily formedv by passing strips of the proper .width through forming rolls and may be easily bent and placed into proper `Arelation, `as shown in the drawing.

The structure is very 'simple in design and inexpensive to manufacture, and is very eflicient in supplying both vertically and transversely extending columns of air to-the water cooling passages throughout the exposed surface of the passages.

We claim:
