RADIATOR.

I Specification of Letters Patent.

Patented July 2, 1918.

Application filed October 8, 1917. Serial No. 195,416.

$ all whom it may concern:

Be it known that I, HARRY Soss1t1N, a citizen of Russia, residing at Philadelphia,

in the county of Philadelphia and State of Pennsylvania, have invented. certain new and useful Improvements in Radiators, of which the following is.a specification, reference being had to the accompanying drawings- 1 his invention relates to radiators and more particularly to an automobile radiator core for the purpose of coohngthe water which is continuously circulated through fit described, claimed, and illustrated inthe- Figure 1 is a fragmentary the jackets of the engine cylinders.

It is the primary object of the present invention to provide a radiator core .of novel construction, whereby the bursting of the radiator or separation of the radiator units through expansion of the water will be obiated.

It is another and moreparticular object of my invention to provide a radiator core made up of a plurality of sheet inetal units which are adapted to be assembled and secured together in certain definite relations to provide spaced, vertically disposed, water passages and a multiplicity of horizontally disposed air passages, said units having adjacent revers'ely curved portions constituting the walls of the-air passages and also affording a maximum space between the adjacent units which form the water passages so as to permit of the expansion of the water.

It is also a further object of the invention to provide a radiator core construction consisting of sheet metal units, which may be readily stamped between suitable dies'into the proper form or shape and then assembled in an expeditious manner, where- -.by the manufacturing cost of such radiators may be reduced to a minimum.

With the above and other objects in view, my invention consists in the novel features of construction, combination, and arrangement of parts to be hereinafter more fully accompanying drawing, in which:

. vation of a radiator core constructed in ac- 'cordance with the preferred embodiment of the invention;

Fig. 2 1s a top plan view Fig. 3 is a detail perspective view of one of the separating units disposed between the vertical tiers of air passages;

front end ele-i Fig. 4 is a similar view of one of the units forming the water passages;

Figs. 5 and 6 are fragmentary end elevations of two units similar to that illustrated in Fig. 4, showing the same in opposed relation prior to their assemblage.

Referring in detail to the drawing, 5 and 6 designate the two sheet metal units which together constitute the opposed walls of each vertical water passage of the radiator. Each of these units is bent or stamped between suitable dies to provide a series of spaced, longitudinally extending plaits 7 therein. The section of the metal unit indicated at 8 is curved laterally and upwardly from the plait 7 and is of uniform width throughout'its length. The adjacent portion of the sheet metal unit is rever ely bent or curved-laterally and upwardly from the portion 8, as shown at 9, to the next adjacent plait 7. The point of juncture of the oppositely curved portions 8 and 9 of the sheet' metal units is indicated at 10 and defines a comparatively sharp, lemgitudmally extending edge or vertex dlsposed substantlally midway between adjacent plaits 7. As will be-noted from the drawing, the radius of curvature of the arcuate portions 8 and 9 of the sheet metal units 5 and (3 is the same.

At the opposite ends of each of the units 5 and 6, the metal sheet is slightly offset laterally, asclearly indicated at 11. In assembling the sheet metal units, they are arranged as indicated in Figs. 5 and 6, and brought together so that at the opposite ends of the units, the convex surfaces of the por-" tions'8 of the unit 5 will seat snugly against the concave faces of the portions 90f the unit (3, the corners or vertices 10 of the respective units being disposed in line with the plaits 7 of the other unit. This relative arrangement of these two units 5 and 6 is clearly shown in Fig; 1, and when thus brought together, the intermediate sections of the two units are spaced apart, the curved portions 8 and 9 thereof constituting the opposed walls of the vertical water passages.

The spaced pairs of units 5 and 6 assembled in the manner above stated, are secured together and held in spaced relationby the sheet ..metal separating units 12 shown in Fig. 3 ofthe drawing, said sheet .metal unit also having reversely curved,.'l,opg itudinally extending portions 13 and 13" respectively of uniform widththroughout the length of said unit. 13 designates the edge or vertex formed at the juncture of the arcuate portions 18 and 13. These arcuate portions of the unit 12 have the same radii as the portions 8 and 9 of the metal units 5 and 6. The plaits 7 at their opposite ends are secured to the units 12, as indicated at it, by being soldered. Thus, there is formed between the adjacent vertical water passages of the radiator, the two series of horizontally extending air passages 15. The portions of the units 12 which are opposed to the respective portions 8 and 9 of the units 5 and 6, extend in convergent relation to such portions of the latter units so that each of the air passages 15 has a lower relatively wide section of semi-circular form, and an upper narrow or tapering section. The curved walls or surfaces .of the sheet metal units provide a maximum surface area for the impingement of the air the water as it circulates through the passages formed by the units 5 and 6 between the bottom and top chambers of the radiator ,'will be effectively cooled; It will also be appreciated that by providing the water passages with the curved wall sections, there may be relatively great expansion of the water in said passages without the separation of the radiator units or bursting thereof, as frequently occurs in radiators of that type having the straight water, passages.

From-the foregoing description, taken in connection with the accompanying drawing, the construction .and manner of assembling theseveral parts of my improved radiator core will be fully understood. The form of the sheet metal units admits of the easy-and quick assemblage of the parts of the core in proper relation to each other and also provides an attractive.variation of the ordinary honeycomb design of radiator core. I have herein set forth a particular relative 'arrangement of the curved sections of the sheet metal radiator units semblingthe same but it is-to be understood that in practice, such form and arrangement is susceptible of considerable modification and. I, therefore, reserve the privilege of thereon, so that thereof and of the same and the manner of ascore including complementary sheet metal units each having spaced plaits formed .therein and. portions projecting laterally from each plait and each portion being reversely and arcuately curved, said units at their opposite ends being secured together and the opposed arcuate portions thereof disposed in concentric relation to provide a vertically extending water passage, and an additional sheet metal unit disposed between the units of adjacent water passages and secured to the plaits thereof to provide two series of horizontally disposed air passages between the adjacent water passages.

2. A radiator core including complementary sheet metal units each having spaced plaits formed therein and port-ions projecting laterally from each plait and each portion being reversely and arcuately curved, said units at their opposite ends being secured together and the opposed arcuate portions thereof disposed in concentric relation to provide a vertically extending water passage, and an additional single sheet metal unit disposed between adjacent water passages and also having reversely curved arcuate sections eXtendlng longitudinally radiias the curved sections of the first named units said addiv tional sheet metal unit at the junctures of its reversely curved portions being secured to the plaits of the first named units and in conjunction therewith providing two tiers of horizontally extending air passages between the adjacent water passages.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
