MODINE, OFRACINE, WISCONSIN, ASSIGNOR TO MODINE MANUFACTURING COMPANY, OFv RACINE, WISCONSIN, A CORPORATION OF WISCONSIN RADIATOR Application filed May 28,

My invention relates to radiators and particularly to automobile radiators.

The invention has among its other objects the production of a device of the kind described which is durable, efiicient and of sim plified construction.

A particular object of they invention is to provide a device of the kind described having improved reinforcing means.

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 of parts herein shown and described, and more particularly pointed out in the claims.

In the drawing, wherein like reference characters indicate like or corresponding parts, a

Fig. 1 is a. front elevation of an automobile radiator embodying the invention;

Fig. 2 is a fragmentary section taken through the improved automobile radiator;

Figs 3 is a section taken on line 3-3 of Fig. 2.

Referring for the present to Fig. 1, the reference character 10 designates generally an automobile radiator embod ing the invention, the radiator being preferably provided with a filling spout ll'and the usual shell 13, or the equivalent which is provided with a. relatively large aperture 14. Asshown, the

4 radiator 10 preferably comprises upper and lower tanks 31 and 32, respectively, which communicate with each other through a plurality of tubes 34, the tubes'34 being preferably formed of relatively thin sheet metal. The ends of the tubes are soldered or otherwise secured in plates 38 which are in turn secured in any suitable manner to the tanks 31 and 32. soldered to the tubes 34 and disposed intermediate the plates 38 are a plurality of cooling fins 35 which are also pref erably formed from relatively thin sheet metal. provided with a plurality of a ertures 36 through which the tubes 34 exten interposed between the plates 38 and so- It will be noted that each fin 35 is 1926- Serial in. 112,315.

cured thereto by anysuitable means, such as for instance solder or the equivalent, are substantially U-shaped bars or members 41 and 44 one of which also preferably engages the ends of the fins 35 and are preferably sold'ered thereto. The bars are preferably formed from heavier material than the tubes 34 and the fins 35 and are adapted to reinforce the radiator core to prevent injury thereto when the automobile is driven over -a rough road or collides with another vehicle.

To assemble the plates 38 with the tubes 34, the fins 35 and the bar 40, I may practice my improved method described in my copending are perfectly soldered, a coating of suitable matter being first applied to the surfaces which are not to be soldered. However, I prefer to assemble the plates 38 with the tubes 34 and the fins 35 and to subseguently secure the bars 40 and 44 in place. 11 Fig. 2 I have indicated at 46 the solder which secures the bar 44 to the plates 38.

The reinforcing device 40 is comprised of the members 41 and 44 which are interposed betweenthe plates 38 and said reinforcing devices preferably include a hollow member 41 provided with a foot 42 soldered to the plate 38 mounted upon the tank 32. As

shown, the hollow member 41 extends through the outermost apertures 37 in the ends of the fins 35, the hollow member 41 being preferably of the same cross section as the tubes 34. In practice the fins 35 are soldered to the hollow member 41 and in some instances I prefer to solder the hollow member 41 to the fins 35 at the same time that I solder the tubes 34 to the fins. Extending into the uppermost end of each hollow member 41 is a -bent bar 44- which is preferably soldered to the tubular member but which may be secured to any other suitable means. The bent bar 44 is preferably soldered to the uppermost plate 38 as indicated at 46. Obviously, the several soldering operations may be simultaneously performed by practicing the improved method which is described in my aforementioned copending application, but I prefer to assemble the reinforcing devices 40 with the remaining parts after the tubes have been assembled with the fins and plates.

As shown in Fig. 3, the hollow member 41 is preferably formed from a single sheet of metal which is so folded that the member has a substantially U-shaped cross section. It is obvious that the hollow members 41 and the bent bars 44 may be readily assembled with the remaining parts of the radiator core as the bent bars may be telescoped into the hollow members 41 during the assembling operation.

Having thus described my invention, it 'is obvious that various immaterial modifications may be madein the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned.

hat I claim as new and desire to secure by Letters Patent is:

1. A radiator comprising spaced tanks, tubular members interposed, between the tanks and communicating therewith, telescoping reenforcing means interposed between the tanks and rigidly secured thereto, and cooling fins secured to the tubular members and to the reenforcing means.

2. A radiator comprising spaced tanks, tubular members interposed between the tanks and communicating therewith, and telescoping reeinforcing means interposed between the tanks, said reinforcing means being secured to said tanks solely by solder.

3. A radiator comprising spaced tanks, tubular members interposed between and communicating with the tanks, cooling fins attached to said members, and reenforcing means interposed between the tanks and rigidly secured thereto, said reenforcing means comprising a hollow member secured to one of said tanks, and a bar projecting from the hollow member and rigidly secured to the other of said tanks, said fins being connected to the hollow member.

4. A radiator comprising spaced tanks, tubular members interposed between and communicating with the tanks, cooling fins attached to said members, and reenforcing means interposed between the tanks and rigidly secured thereto, said reenforcing means comprising a hollow member secured to one of said tanks, and a bar projecting from the hollow member and rigidly secured to the other of said tanks.

In testimony whereof, I have hereunto signed my name.

ARTHUR B. MODINE.
