ATTO RNEY Patented May 2, 1950 Fred M. Young, Racine, Wis., assignor to Young Radiator Company, Racine, Wis.

Application September 12, 1947, Serial No. 773,612 6 Claims: (01. 257-125) The principal objects of the present invention are to provide a cradle within which to secure together suitably designed headers of a radiator and form a unit structure with maximum strength and longevity, particularly where the device is subjected to vibrations, such as when mounted on a tractor, truck, engine support and the like.

Other objects of my invention are to provide a unit structure having means for securing it to the supporting frame in a manner whereby the unit will be firmly held to the supporting frame, and without imparting harmful strains to the radiator tanks and the core, whereby the connections are made between the cradle and supporting frame by means of detachable bolts which bind the cradle firmly to the frame.

Generally stated objects of the present invention are to provide a U-shaped cradle structure with means whereby the headers of the radiator are firmly held in the cradle in a manner which will protect the radiator headers and core against injury from vibrations and strains.

To these and other useful ends my invention consists of parts, combinations of parts or their equivalents and mode of assembly as described and claimed and shown in the accompanying drawings in which:

Fig. 1 is a front elevational view of my improved radiator unit illustrating the holding bolts after being inserted in the opening in the cradle.

Fig. 2 is a side elevational view of the unit as shown in Figure 1 less the holding bolts.

Fig. 3 is a bottom view of the unit shown in Figure 1.

Fig. 4 is a sectional view taken on line 4-4 of Figure 1.

Fig. 5 is a sectional view taken on line 5-5 of Figure 2 showing the right hand lower corner of the unit.

Fig. 6 is an enlarged sectional view of the outlet fitting shown in Figures 1, 2 and 3.

Fig. 7 is a fractional section of the inlet connection to the upper header illustrating the manner of securing it to the header, and Figure 8 is a rear view of the lower header outlet.

As thus illustrated the upper header is designated by reference character A and the lower header is designated by reference character B. The cradle in its entirety is designated by reference character C and the radiator core is desig-- nated by reference character D.

Core D of my device comprises preferably three rows of flattened tubes In with the wide sides of the tubes arranged transverse of .thecore as shown in Figures 4 and 5, the tubes extending through a multiplicity of closely spaced fins H. The headers have somewhat similar tube plates l2 and I2 with flanges 9 through which the ends of tubes l0 extend, and are bonded thereto as illustrated in Figures 4 and 5.

Header A is shaped about as shown in Figures 1 and 2 with spaced inwardly projecting emboss ments [3 so as to add strength to the header, the ends of this header being tapered as at I4 and the header being provided with a projection 45, having a closure cap l6. An over flow tube I1 is secured to member I5 as indicated in Figure 2, this over flow being bent downwardly as illustrated in Figure 2,the end terminating preferably as at l8 and being connected to a long drain pipe I!) shaped about as shown by dotted lines in Figure 1, the upper end being connected to tube 17 preferably by a synthetic sleeve 20.

Tube l1 preferably extends through header A (see Figure 2). Tube I9 because of its shape and manner of connection to tube l1, may be made of low priced material such as steel or the like, and is clearly replaceable if injured. Tube I9 is secured to the side plates of the cradle as will hereinafter appear.

Upper header A and its tube plate 12 is considerably Wider than tank B and is provided with an inlet member 25, the lower end being circular in cross section and adapted for convenient connection to a rubber hose which is connected to the engine jacket. The rear side 26 of header A is flat, and the upper edge of this header is depressed somewhat as at 27 and having secured thereto a bracket 28 for holding the engine hood into position. The forward end of member 25; is secured to the header as follows (see Figure 7) :1

It will be noted that the part that extends into. the header is considerably narrower than the: rear end of this member; therefore the part that. fits into the header is necessarily considerably,-

wider than its depth. This part is therefore ob-- long in shape (not shown), the opening being; flanged as at 29 and is adapted to fit snugly around the inlet 25 at this point and being bonded thereto. The inner end of inlet 25 at its top extends upwardly and rearwardly as at 3E! and is adapted to lie under member 21 as illustrated and is preferably bonded and riveted to this member at the point of contact. The forward end of member 25 is cut away at an angle as at 32 making it possible to insert the forward end of member 25 into flange 29, after which member 30 may be bonded and riveted to the header.

it will beseen thatmember 25. will be firmly held to the header by member 30 and flange 29, Whereas without member 30 member 25 would not be stable enough for the purpose.

It will be seen that I have provided an upper header having an inlet with adequate capacity and strength and a novel over flow pipe.

On the forward side of headers A and B I provide a buffing or rubbing strake 33 having a length a d pe about s h w in Figu es :1 an .2 and being spot welded or riveted to the header plate and preferably bonded to this plate. This strake is provided to prevent contact of theheader with fitting members or accessdries might result in injury to the thin delicate material of the header.

Lower header B is provided with a header 7 plate l2 having flanges 9 through the lower ends of tubes l6 extend and to which the tubes are bonded.

I will now describe the shape of header plates 2 and J2 the m nne f at achin p ates to the h ad tan s Th re imeters .of heade s a d I 2 ar sh p ass o-wh in Fi u e i a d whe ein ima es 42 are co nected to plates nal-2 y means at :n ie tiqns 43 which f wells into h ch flan es 4 at the h ad r t nk ext nd he. side an end wall of ach he der ta k being extend d out rd y as a 5.- Thn it w l be s e ha when the ta k is p ope ly s ned as illu t a e the e wi l b a a c m lation o b n ma eria 435 iv rm s'atriple h d e w en the ader plates and he der so fa s th hcadar -r lates are, c c n d, ya som hat s m lar and the e o z t i n th u h ne ssa to. il ustrate in detail an upper header.

' An end portion of the upper endof *the rear flan e o mem ers 55 s=cut awayso as to; clear the header. To take the place of this-cut away portion, I provide :plates 1'61, which are shaped about. as shown in :Figure 2, then forward :edges being welded; to members 55 as Eta-6'2. Theup! per edges. of members i6l'lie on the ends of the rear portion of headers A and have soldering holes .63 so these members may be firmly-bonded to member A. These members do notcontact inwardly. slightly as at :65. I providea heavy 7'5 U-shaped bracket 66, the ends of which lie under the ends of the base of members 55 and are riveted thereto as at 61, the base lying against the bottom of header B. The lower ends of the flanges of members 55 are shaped as shown in Figures 1, 3 and 4. These members are offset inwardly slightly as at 69 having downwardly extending'portions 1076 which lie on the sides of tanlcgB, each having solder holes 68 to facilitate the bonding operation. The lower ends of members ID are folded under member 65 as at H, {see Figures 2 and 3) and being spot welded or riveted to member 66 and bonded thereto if thought desirable.

Member 6,6 has openings 15 which are large enough to freely receive the heads of bolts 16, hcli heins carr ge bolt typ w sq shanks "Tl. Openings 15 are on their inner sides provided with cut away portions 18 forming keys for the reception of sljranks l1. Embossments a? and "A1 ar made r e e o gh to c e t c of bolt 16 wh h y a in rt d nt gs l5 and moved to-th position shown in a I e 3 st) there is never a contact between these hea ahd he hettom of t ta .I il be. n ted that e flanges o c n C are iurther apart than the, width .of header B and that these flanges are therefore offset inwardly as at 66. It will also :be noted that the up u ned, ends o b ck i are s a e a s t distance from the ends of the lower header B, h r ore s i ht va -when x si nan ant a tion betwe n memb s I) an Q w l be e m t ed,

Under some circumstances it may be desirable to prevent metal. .to metal contact between the bottom of header B and member 66. Wherrthis is thoughtzdesirable a thinsheetof yielding material 19 is provided-to accomplish this result (see FiguresA andz5).

I will noW describa-the outlet element offmember- B.

Member B is out away in its-rear lowercorner betweenpoints a'nd' 361(se6'Figllre6) thuspro viding an elongated Leshaped opening the header tank: An -element 8 is -fian-ged as at? and 89. Flange 88 is--adapted t9surroundthree which registers with flange 89 and with the rear surface of the tank Which surrounds three side of the cut away portion on the rear of the tank and being bonded to these parts.

Thus it will be seen that an elongated opening in the tank is provided having area about equal to the area of member 556 so as to form a free outlet for the cooling liquid and a reinforced connection between member 9% and the tank.

It will be seen that the flanges of members 55 shield the corners of the flns. In order to make full use of the corners of the core I provide openings 92 in the flanges thus to provide free air passageways through the corners of the core so as to provide maximum heat exchange capacity for the core.

It will be seen by scrutinizing the various figures that applicant has provided a un t which conforms to the preamble of this specification; that the unit is easily manufact ed at low cost and neat in appearance and eflicient and well protected. for storage and shipping purposes.

It will be understood that applicant does not wish to be limited to the specific design disclosed; that many minor detail changes can be made without departing from the spirit and scope of my invention as recited in the appended claims.
