The radiator'in which the present invention has been embodied includes al c'oreunit xnadeup of a ynumber of vpreformed plates 19 suitably secured together to afford av series of spaced lwater passages forfthe'iiow ofl air therebetweemwith inlet and outlet headers or tanks' at opposite ends of the Water passages, and a hoop or and anchor or support the assembly in an ornamental shell or casing which -is mounted on the chassis frame of the vehicle.

It is one of the primary objectsof the present invention to provide an improved anchorf relation with each other, 25 arranged with respect tothe 4core that the age strap lorband for supporting the tank and core vassembly in the shell which will firmly hold the associated parts in proper core will be freed Vfrom x the imposition of thrusts or stresses incident to -frame Weaving, road shocks or the like.

@ther objects and features of advantage will become apparent during the course of the is mounted the radiator.`

following specification when taken in connectionvr with the accompanying' drawings illustrating a preferred embodiment of the invention. f

In the drawings:

Fig.x1 is a rear elevation of a radiator mounted upon av vehicle chassis frame and illustrating the application of the invention.

Fig. 2 is a fragmentary enlarged view of a portion of the structure shown in Fig. 1.

Fig. 3 is a detail view illustrating a slight modification. y

Referring specifically to the drawings,the reference numerals 1-1 indicate a pair of longitudinally extending chassis frame members, and 2 is atransverse member on which stance, the kcooling portion or core `3 of the radiatoris shownas of the well known cellular type, preferably consistingl of a number band encircling the core" 15 and .tanks to hold them'in assembled relation 'l portion of the core.

This particular joint isdescribed .more/fully in my pending application for'Patent Serial No'. 388,086. y l, 1^k Each of the straps 13 and le is provided at suitable intervals withl rearwardly and outwardly extending ears 17 for attachment as vbvgmean's of studsj18 tothe rearward edge of the customary ornamental shell or casing gl. i

y19.V A fU-shaped supp'ortingstrap 2 1'se ycuredas bymeans of bolts'QQ to the ,chassis frame member 2 hasits upwardl extending endportions riveted orotherwlse fastened 'to' the sidewalls of the shellj19` wherebyl the shellis supported on the 'frame and turn Disconnection-of' the joint is'presupports, through the ears 17, of the anchor* age hoop or bands, the tank and core assembly. To steady and hold the assembly firmly in the shell or casing, a channel plate 24 may be secured to the bottom strap 127 and provided at opposite ends with slotted feet for engagement beneath the fastening studs 22.

In order that strains and side thrusts received by the anchorage straps 13 will not be imposed upon the sides of the `core 3, it is proposed to provide a lateral offset rportion 25 between the strap portions 12 and 13 of slightly greater dimension than that portion of the core overhanging the side wall of the bottom tank 5, so that the lateral offset portion 25 will contact with and abut the side wall of the tank and the adjacent portions of the side of the core and strap 13 will be spaced slightly from each other particularly at the connection or joint between the tank and core. Thus the likelihood of damage to the thin and delicate metal of the core will be materiallyl reduced and any stresses will be transmitted thru the lateral offset or foot directly to the stronger metal of the header or tank. l

In the event the bottom and side portions of the hoop are formed in separate pieces as may sometimes be desirable, the invention may take the form illustrated by vFig. 3. Here the end of the bottom strap 30 is secured as by soldering, welding or otherwise to the side strap 31 and the lower end of the side strap is inclined outwardly vaway from the side of the core and provided with .a lateral or inturned foot 32 having a dependent flange 33 for abutment with the side Wall of the bottom tank. As in the arrangement previously described, the core and par* ticularly the lower portion thereof secured to the tank will be freed of the damaging strains.

Various other forms of the invention will be apparent to those skilled in the art and there is no intention to limit the invention to the exact details referred to herein.

I claim:

1. In a radiator, a shell adapted to be mounted lon a support, a radiating unit encased within and directly supported through said shell, said unit including a bottom tank having an outturned marginal flange, a Core secured along its underside to said outturned flange with portions thereof overhanging the side Walls of the tank, and an anchorage strap for lmounting. the unit on the shell, having a portion thereof extending adjacent the side of the core with a lateral .attachment projection and another portion inset .adjacent thejoint between the core and outturned flange of the tank for Contact with the side wall of the tank, said inset portion being of slightly greater dimension than the, overhang of the core whereby to hold the side portion clear ofthe core so that thrusts and strains are imposed directly on the tank through said inset portion rather than on the core and the joint between the core and tank.

2. In a radiator, a heat transfer unit, including a tank having an outturned marginal flange, a core having one end joined to saidflange and overhangino the side walls of the tank, and an anchorage band contractible about the core and tank to hold these parts assembled, portions of the band adjacent the joint between the core and outturned flange being inset for a distance slightly exceeding the core overhang for direct thrust engagement with the wall of the tank.

3. A contractible assembly and .anchorage hoop for encircling a heat4 transfer unit of the type wherein the core is offset outwardly beyond the side walls of an end tank, includ ing a strap adapted to extend closely adjaA cent the side of the core, and provided with an inset portion corresponding to but of a dimension .slightly greater .than the core olfset for direct thrust engagement vwith the tank wall.

' In testimony whereof I aliiX my signature.
