To all whom it may concern."

lie it known that ll, PETER Maristas, a citi` zen of the United States, residing at Chicago, inthe county of Cook and State of lllinois, have invented certain new and useful Improvements in Radiator Constructions, of which the following is a description.

My invention belongs yto that general class of devices known as radiators, and particularly the type of radiator used on automobiles or the like or in connection with'explosive engines for carrying off or dissipating the heat from the cooling fluid employed in the circulating system for cooling the engine. The invention has among its objects the production of a construction of the kind described that is simple, durable, attractive, efficient and satisfactory for use wherever found applicable. Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combination 0f parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts, v l

Figure l is a view in elevation of an autoniobile radiator;

Figure 2 is a front elevation of a portion of the radiator;

Figure 3 is a sectional view taken substantially on line 3-3 of Figure 4;

Figure 4 is a sectional view taken substantially on line 4-4 of Figure 3;

- Figure 5 is a perspective view showing one side of a portion of one of the tubes;

Figure 6 is a similaiview showing the opposite side;

Figure 7 is a view of the preferred form of spacing member; and

Figure 8 is a disassembled view of a spacer and adjacent portions of two tubes.

Referring to the drawings,- 1 represents the usual shell over an automobile radiator giving a finish to the same and within which are usually arranged the tanks which are connected with the circulating system, or as desired. 'llhe radiator part 2, which is the subject matter of the present application is ordinarily mounted within shell l, it being understood that the part l and associated parts form a part of the cooling system and need not be described in detail, but may be as referred. The radiator consists of a plurahty of tubes whichare spaced from each other so as to permit the passage of air around the tubes so as to take up the heat therefrom. The tubes in the preferred construction consist of mating parts 3. These parts are formed as at 5 and 'thence offset at the front and back edges at 6 to provide what may 'be termed side or edge flanges 7-7. lf also prefer to groove or form ridges 8 in the tube parts 8 so as to form a series of similar cha-mbersor depressions 9. 'lhe several ridges may be indented or similarly formed as at l() so that therev may be also a free passage of water or the cooling Huid through the tubes. The tubes are arranged together with the ridges S'Opening inwardly,

-as indicated and most clearly shown in Figures 3 and 4. Referring t0 this ligure it will be noted that the indentations are arranged alternately Vso that the passage is tortuous, this also increasing the cooling area. With the indent-ations 8 turned inwardly, this provides a series of notches or grooves on the exterior faces of the two tubes. Arranged between adjacent tubes is a spacer 4 which preferably consists offa sheet 16 substantially corrugated, or that is, crimped or bent, preferably as shown, substantially zigzag, or to' provide a plurality of tl-shaped passages when the spacer is in place. As shown, the same is formed with the edges 11, the saine being preferably indented at 12 as most clearly shown in Figure 7. The edges are preferably formed U-shaped as at l4-15, but are formed with 'flat faces so that the faces 14`may engage and closely fit the flanges 7 of the tubes. The several tube parts 3 are secured together by soldering, brazing, or the like, and the spacers 4 arranged between adjacent tubes and secured thereto in a similar manner. It will be noted that the edges 1l fit into the grooves formed by the indentations 8, the notches or indentations 12 in the spacer clearing or straddling the ridges formed by the indentations l0. rlFhe spacer and tubes thus substantially interengage and when theJ parts are all secured together a very strong, rigid and durable, as well as most attractive construction isproduoed.

It will be noted by referring to Figure 3 that as the waterpasses through the passages b in the tubes and the air through the lbb lll@

' assaces a formed in the s )acers between the circulated or diffused in the radiator so asl to contact with substantially all of the outer Walls of the tube. may flow almost directly through the tubes through spaces formed at the indentations 10 (see Figure 4) and this has a tendency to thoroughly circulate the water inthe radiator so that the device operates very efiiciently. The same has a very attractive appearance.

Having thus described my invention, it is obvious' that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact construction, arrangement and combination of parts herein shown and described or uses mentioned. What I claim as new and desire to secure by Letters Patent is l 1. A plurality of tubes each comprising a. plurality of plates offset between their edges to substantially provide a channel web a-nd a pair of side flanges, said tubes secured together at their flanges, the plates having inwardly extending ribs between the fianges and arranged with the ribs of one disposed substantially midway between the ribs of the other', said ribs terminating flush with the plane surface of their channel webs, and a spacing member arranged between the tubes and secured thereto, said spacing member having means interengaging with said tubes for preventing relative lateral movement therebetween.

2. A plurality of tubes each comprising a plurality' of plates offset between their edges to substantially provide a channel web and a pair of flanges, said tubes secured together along their flanges` the plates having inwardly extending ribs struck up from the channel webs between the flanges and arranged with the ribs of one disposed substant-ially midway between the ribs of the other, said ribs terminating flush with the plane surface of their channel webs, spaclng members arranged between the tubes and secured thereto, each of said spacing members comprising substantially a corrugated plate having its edges U-shaped with the center V-shaped, the V-shaped edges of the spacing memberl alternateljY engaging the adjacent tubes at the exterior' of the ribs.

A portion of the water 3. A pluralit of tubes, each comprising a plurality of pla to substantially provide a 4channel and anges along the sides ofsaid channel, said plates arranged together at their flanges, the plates having inwardly extending ribs between the flanges with transverse indentations on. the exterior of said ribs, and said plates beingarranged with the ribs of one disposed substantially midway between the \ribs of the other, spacing members arranged between the tubes and secured thereto, cach of said`spacing members comprising substantially corrugated plates having their edges U-shaped with the center V-shaped, the V-shaped edges of the spacing member alternately engaging the adjacent tubes at the transverse indentations at the exterior thereof.

4. In a radiator, a plurality of tubes, each having a plurality of longitudinally spaced indentations extendilnT across its width` and longitudinally extendlng ribs at spaced in` tervals in said indentations, and spacing members arranged one ybetween adjacent tubes, said spacing members being constructed to interengage said ribs and indentations.

5. In a4 radiator, a plurality of tubes, each tube comprising two parts arranged together, said tubes having a plurality of longitudinally spaced indentations extending across its width at opposite sides, and longitudinally extending ribs at spaced intervals in said indentations and forming side walls thereof extending interiorly of the tubes, and spacing members arranged one between adjacent tubes` said spacing men1- bers constructed to interengage said ribs and indentations.

6. In a radiator, a plurality of tubes. each tube comprising two parts arranged together, said tubes having a plurality of longitudinally spaced indentations therein extending across the width of the tubes on opposite sides thereof', a series of longitudinally extending ribs at spaced intervals in each of said indentations` and spacing members. arranged between the adjacent tubes and constructed to engage therewith at the indentations therein, the spacing members being formed with laterally spaced longitudinally extending indentations engaging said ribs on the tubes.

`In testimony whereof` I have hereunto signed my name in the presence of two subscribing witnesses.
