RADIATOR REENFORCEMENT Filed Sept. 15. 1924 I V erbium;

COMPANY, OF DETROIT, MICHIGAN, A- CORPORATION OFfIYIICI-IIGAN RADIATOR nnnunononiuniyr q Application filed September 15, 19241" sriaifiubfirsareaf The invention relates to the constructionof radiator cores and has for its object the reeniorcement and mechanical strengthening of the structure and particularly the connection between the upper and lower tanks. To this end the invention consists in the construction as hereinaf'ter set forth.

lVhile my improvements are applicable to various types of radiator core construction, I shall specifically describe its application to the fin and tube type, in which a series of vertically extending tubes have a series of laterally extending fins sleeved thereon and soldered thereto, the upper and lower water tanks being formed by header plates secured to the tubes in the same manner as the fins and having the tank bodies soldered to said header plates. Such construction is mechanically Weak and it is one of the objects of the present invention to reenforce the same.

In the drawings:

Figure 1 is a cross section through a portion of radiator to which my improvements are applied;

Figure 2 is an end elevation;

Figure 3 is a perspective view of the reenforcement strip,

As shown, the radiator is formed of a series of vertical tubes A-and a series of laterally extending fins B spaced to form the intermediate air cells C and soldered upon the tubes. D and E are respectively the top. and bottom headervplates, which are similar'to the fins but formed of heavier gauged metal, being also provided with the marginal flanges F for attachmentto the tank bodies Gr and H.

My improved reenforcement comprises a' metallic strip I, preferablyof heavier gauged metal than that used in the construction 01 other parts of the core. This strip is formed with an upper portion J which is curved to conform to the shape of the upper tank G, a lower portion K fashioned to fit around the lower tank Hand an intermediate portion L extending between said tanks. This interme diate portion is of greater width and is bent I to form the outwardly-extending flanges M-or a channel-shaped horizontal section. The flanges M are tapered ofi at their upper and lower ends, as indicated at O and P, but extend to 'slightfly overlap the tanks G and To further increase the reenforcement or the core the strip'I is'p rovid'ed withstruckout portions Q and R, which extend inwardto lie adjacent respectively to the upper and lower headerplatfeslj) jandjE. These portions Q, and R thus'form' angle'flanges, which together with the portions J and K are soldered to the tanks. This forms a rigid connection, while the trussing effect of the intermediate por-' g tions L with the angle flanges M will impart rigidity to the whole structure.

It is obvious that the reenforcement just described can be easily formed and applied to the core without any other change thestructure.

What I claim as my invention is:

1. The combination with a radiator core in cluding'top and bottom tanks, of a reent'orcement comprising a strip arranged at the side" of the radiator having portions overlapping and secured to said tanks, and an inwardly extending angle flange bracing the horizontal wall or each of saidtanks.

2. The combination with a radiator core in- 7 eluding top and bottom tanks, of a reenforcement therefor comprising strips arranged atv the sides of the radiator overlapping and a secured to said tanks, and angle flanges pro- 7 jecting inward from said strip respectively 0 secured to the bottom of the upper tank and top of the lower tank;

' 3. The combination with: a radiator core including a tank, of a reentorcement therefor comprising a strip having a portion overlap- "s5 ping and secured to the side of sa1d tank and provided with a struck-out portion lying in juxtaposition to the horizontalwall ofsaid tank.

including top and bottom tanks,-of a reentorcement comprising a strip extending be tween said tanks and secured thereto, said 4. The combination with a radiator core forcement comprising a metallic strip extending at the side of the radiatorbetween said top and bottom tanks, overlapping and secured to the same, the portion of said strip intermediate said tanks being outwardly flanged to form a channel section, and an angle flange projecting inward from said strip and secured to a horizontal wall of the tank.

6. The combination with a radiator core includin g top and bottom tanks, of a reenforcement therefor comprising a strip arranged at the side of the radiator, and means carried by the said strip for embracing the ends of the said tanks and for spacing the bottom of the upper tank from the top of thelower tank. V

7 The combination with a radiator including upper and lower tanks, of a reenforcin'g member having portions embracing one of the c said tanks and spacing the one tank from the other.

In testimony whereof I 'aflix my signature.
