JAMESA.WIII'.|2Ev OFk LocKPon'r, yNEW YORK, AssIGNoR To HARRISON RADIATOR fi CORPORATION, OF LocKPoB-r,y NEW YORK, A oonronArioN or `NEW YORK PATENT FFIC pnAi-)IATOR AssnMBLY Application inea'Augusty 214, i929. serial No. 388,085.v
This' invention v:relates to radiator' strucf iuresand particularly to the constructionof tliege'neral-type of radiatorthat forms a part ofthe cooling-system ofan internal' combustion engine such -as is used oninotor vehicles. V
As ordinarily constructed, these radiators include acore Vor heat radiating element'and a pair of tanks at opposite ends ofthe core constituting inlet y and ,outlety headers for the vcore,`and' the present invention has todo with aband or hoop to'fencircle and "hold the tanks and core in proper" assembled relation and afford a connectionjwith theusual i' ornamental'shellorvcasing.l
One of the objects of the'inve'ntion is to provide animproved connection between ad# jacentfend portions of the' hoop which will l eliminate loose parts to be assembled,'reduce 1 the number of'part's required, simplify manufacture, lessen production costs, facilitate assembly, and insure a positive'interlockbetween the parts.r ,K
' A further object is toprovide' an imqaroved yconnection involving interengaging wedge or cam surfaces lmovable'fone on the other to effect the contractionv of the hoop tightly about the corefand tank assembly. i
' Additional objects and-features of advanj tage will become apparent during vthe course 'of thev followingspecification 'when taken in accompanying drawtion applied thereto.
Fig. 2 is a side elevation 'of the radiator shown in Fig. 1. f j
.1 Fig.'3 isa fragmentary detail View of a portion of the structure shown in Fig. 1, onl an enlarged scale.` .A Fig. 4 is a detail perspective'view of the interlock-'between adjacent ears of the strap.
Fig. 5 is `a side elevation of the interlock. Referring to the drawings, the radiator in the present instance, is'shown as comprising a pair of spaced inlet and outlet headers l and 2 respectively, having interposed therebetween a core or heat radiating element 3' preferably of thewell-known cellular forma# tion, comprising a number of preformed ylates arrano'ied in s aced' oairs to rovide water passages connectingV the headers with spaces for air flow between the several pas` sages. To hold the core and tanks in proper- [assembled relation andto'also provide an anchorage therefor,it isproposedt'o surround V the core and tank assembly with an en- I circling hoop or band. .This band may coin'- i prise a single strap secured together at ad- ]acent ends or a number of straps suitably ysecured together. 'In the instant case, the
hoop comprises al top portionv 5, side portions -6-6, and a bottom portion 7*. At
thefloweryend of each side "strap 6A there is preferably provided a lateral offset 8 for engagement with the side wall of the tank 2 to space the adjacent portions of the strap and side of the core from each other so thatstrains andside thrusts in the straps arey transmitted to the lower tankQ rather than onV the thin and more vdelicate metal of the core; Thelowermost extremities ofthe side of the core in a vmanner to be later referred to.
The present invention lis particularly'con-v `cerned-with the` connection between the upi per ends of the side straps Gand the adjacent endsof the top strap 5. Thezembodiment of ,c 1
the invention as shown kin thedrawings involves the formation of reverse-ly bent flanges 10 and' ll on the straps 5 and6 respectively, which provide channeled end portions on the respectivestraps which openupwardly in one instance, 'and downwardly in the other, and l which oppositely Opening channeledy portions are adapted for internesting engagement.` IThe line on which the respective flanges are reversely bent is inclined or diagonally disposed so that there are afforded wedge or cam Vsurface which ride one on the other when they Y two straps are moved laterally relative to each other. The wedging action which takes Y place duringthe assembly of the vparts be- 'causeof the inclined' cam surfaces, serves to contract the hoop and draw the straps tightly about the core and tank assembly. This connection eliminates all loose parts such as bolts and nuts, and provides a simple and economical yet very effective and efficient joint. No tools nor special skill are requirec., and the connection can be effected in a minimum amount of time.
It will be noted that the end portion of the strap 5 at the lower part of the incline is projected laterally beyond the side of the strap 6 to afford a projection or ear 13 which, after the parts are brouoiht into proper wedging relation, may be bent through substantially 90 from the plane ofthe straps to thereby close the channel formed by the flange 11 and prevent disengagement of the internested parts. For the protection of werk- Inen, sharp edges are eliminated on this tab 13 as far as possible, and the corners are rounded. It will be obvious, of course, that in the event it should ever become necessary to disassemble the radiator, the ear 123 may be readily bent back its original position to open the channel and allow the cam surfaces to be slid olf one another.
In addition to holding the tanks and core in assembled relation, the encircling hoop may also be utilized to anchor or mount the assembly in a radiator' shell. For this purpose there may be provided on the'straps 5 and 6 rearwardly and outwardly extending ears or feet 15 for attachment as by means of screws or studs 16 to the rear edge of an ornamental. shell or casing 1'?, which supported by the strap 18 riveted or otherwise secured as at 19 to the shell and passing beneath the lower tank 2. A pair of studs or bolts 2O connect the strap 18 with a support or chassis frame member 21, whereby the shell is mounted on the frame and in turn supports through the anchorage hoop the heat radiating unit. 'llo steady the unit in the shell, the lower strap 7 of the hoop may be provided with projection er feet for insertion beneath the heads of the fastening studs 20.
lVhile the above description has been more or less specific as to structural det l.is to be understood that the invention is not limited to the exact details described, but that such modifications may be made as come within the scope of the appended claims.
I claim:
1. In a radiator seructure, the combination with an assembly of a heat radiating unit and headers therefor, of a band surrounding the assembly and having interengaging inclined surfaces movable one on the other to contract the band and means to prevent the disengagement of said inclined surfaces.
