CHARLES WM. OWSTON, OF DETROIT, MICHIGAN, ABSIGNOB TO MUCORD RADIATOR & MIG. 00., O! DETROIT, MICHIGAN, A CORPORATION OF MAINE.

RADIATOR.

Application filed July 14, 1924.. Serial No. 725,799.

To all whom it may concern: a

Be it known that I, CHARLns WM. O ws'roN, a citizen of the United States, reading at Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Radiators, of which he following is .a specification. v

This invention relates to radiators for automobiles and other motor vehicles and has particular reference to the manner of providing an opening in one of the walls of the upper tank for passage of the over-flow or vent tube.

In the accompan ing drawings Fig. 1 is a rear e evational view of a radiator embodying the features of my invention'; I v Fig. 2- is a fragmentary perspective view of the upper tank, showing the tube open- 111 Fig. 3 is an enlarged sectional view through the walls of the tank at the-opening, on line 3-3 of Fig. 2; and

Fig. 4 is asectional view on line 4-4 of Fi 3.

The radiator shown in thedrawings has an outside casing or shell 1 containing a core The core may be of the fin and tube or of thecellular type and has upper and lower water tanks 3, 4. Belting stri s 5 are carried at the sides of the core an are secured to the shell for suspending the core therein.

The vent tube 6 is at the rear of the radiator and has its upper ortionextending into the top tank 3 throug one of its walls. In the particular type of radiator shown, the tube extends obllquely through the rear wall 7 of said tank between one end of the tank and its water jacket hose fittin 8. The

opening in said wall for the tube, in accordtank is bent inward, while the metal ortion 7" on the opposite side of the slit is ntoutward, as shown in Fig. 3. These portions are also given a curvature conforming to that of the tube 6 and provide an open- Moreover, in making the opening in this manner, the actual opening in the plane of the slit approximates the diameter of the tube and is one which bears substantially continuously around the entire circumference of the tube so that packing (Li-the ea s, as

opening with 'solde'r to prevent heretofore, is avoided. The edges of this opening being in a plane transverse to the portion of the. tube extending therethrough allows for this continuous contact, as shown in Fig. 4.

With the tube 1 in close to or against the tank wall 7 an tfien goin through it obliquely, the elliptical or rat er elongated oval opening heretofore made in said wall did not have all around contact with the tube. This made gaps between the tube and the edges of the opening, with the result that v packing of the opening around the tube with solder was required tosecure a water ti ht joint. With my invention, there is a re atively large bearing area of tank wall for theiube, not only (providing a support for the tube but provi ing a proper and tight o1ut.

Following the customary ractice, the upper end of the tube 6 exten s into the filler neck 9, of the radiator, "a shown in dotted linesin Fig. 1 'to'beabove the water level.- The lower en core and directs theoverflow downward, as shown'.

I claim as my invention: -1. In a radiator, the combination of a tank and an overflow tube extending there- I through, the tank having one wall rovided with a slit and the metal portions o thewall on op osite sides of the slit being respectively bent inwardly-and outwardly from the or the 60 of the tube is outside the 5 plane of the wall to conjointly form an opening for receiving said overflow tube, and opposed bearing surfaces for the said tube, the diameter of the opening being substan-. tially ual'tojthe outside diameter of the tube an the bent ortio s. h

metal adjacent the opening extending in parallel planes at an angle inclined to the plane of the wall.

2. In a radiator, the combination of a tank and an overflow tube extending therethrough, the tank having one wall provided with a slit and the metal portions of the wall on opposite sides of the slit bein respectively bent inwardly and outward y from the plane of the wall to conjointly form an opening for receiving said overflow tube, and opposed bearin surface for said tube, the diameter of t e opening being substantially equal to the outside diameter of the tube and the bent bearing portions of the metal adjacent the opening extending in arallel planes at an angle inclined to the p ane of the wall, said bent bearin portions of the wall being curved to snug y fit the tube on opposit sides thereof throughout the lengths of said portions.

3. In a radiator for motor vehicles, the combination of a core having a tank, and a vent tube having a portion extending into the tank obliquely through one of the walls thereof, said wall having an opening for the tube to pass through, said opening being formed to have its edges in a plane transverse to the tube portion extending there- 'through and having substantially continuous contact with the tube all around the same, said wall having tube bearing surfaces on opposite sides of'said opening.

4. In a radiator for motor vehicles, the combination of a-core having a tank, and a vent tube having a portion extending into the tank obliquely through one of the walls thereof, said wall having its vent tube opening formedby slitting the tank wall and then pressing the wallp'ortions on opposite sides of said slit out of the plane of the wall and in opposite directions to provide relatively wide bearing surfaces for the tube and cause the vent opening to fit all about the tube.

In testimony that I claim the foregoing as my invention, I aflix my signature this 28th day of June, 1924.

CHARLES WM. OWSTON.
