l Specification of Letters Patent.

Patented Apr. 5, 1921.

Application filed January 16, 1918. sem No. 212,088.

To all whom 'it may concem:

Be it known that I, CARL MCNEELY, a

citizen of the United States, residing at vention being to produce a radiator embodying top and bottom headers and connecting water tubes in communication with said headers, the construction of the radiator embodying walls of such formation and rela- I the fracture or in tion to each other as to present eflicient cooling surfaces of large area in small space as well -as prevent the bursting or fracture of said walls when the water freezes in the radiator.

r A radiator constructed in accordance with the present invention will maintain itself in a water-tight condition notwithstanding the frequent freezing of water therein, thus greatly reducing the expense of motoringv and the trouble and annoyance incident to "ury of the\rad1ator and fre uent repairs, ue to freezing. 1

ith the above and other objects in View,

the invention consists in the novel construction, combination and arrangement of parts,

herein described, illustrated and claimed.

' drawings In the accompanying V Figure 1 is a front e ovation of aradiator embodying the present invention.

Fig. 2 is a vertical transverse section through the same.

Fig. 3 isa horizontal cross section-on the line 3-3 of Fig. 2.

Figs. 4 to 8 inclusive are cross sections through different forms of water tubes.

The radiator contemplated in this invention comprises top and bottom headers 1 and' 2, respectively, and water tubes 3 which I ordinarilyextend vertically between the top and bottom headers and are in constant communication therewith.

In carrying out the present invention, the

dished curvilinear front and-rear walls i'and linear wa tube j ments 5, respectively and also comprise an inwardly dished curvilinear bottom wall 6.

The top wall 7 is shown as flat so that the curvilinear in cross section.

Each of the water tubes 3 connecting the 1 top and bottom headers and communicating therewith vforftransferringthe water. from one header to the other, is also formed with a pluralitliyfof inwardly dished \and. curviof lbein the same as the inwar indicated in Figs. 4 to 8 inclusive,'e ach of the tubes 3 may be of various shapes in cross section, the'cssential feature being that each, 1 i I comprises one or more inwardly dished lllthe object and pu ose therev dished. .walls o the top and bottom hea ers. As

wallswhlch is capable of being pressed out- 'wardly when water' freezes therein without fracturin or injuring such; wall and the tube of w ich it forms a part.

From thef'fore it-will now be understoo that each of the water circulatingcompartments of the radiator embodies one or more inwardly'dished v oin'g'description'taken inv connectlon' with t e accom anying drawings walls preferably curvilinear in cross section.

Such a wall presents a largercoolin area than a-flat surface" and allows fort e expansion' of the water asit freezes and subsequently enables ice to thaw without in any way injuring said. wall or walls of the water;

.compartment.

.' I claim; v a

1. In a radiator, the'oombination of a top header, a bottom header, and a series of vwater tubes connecting saidv top and bottom headers and communlcatingtherewith, said ,top and bottom'headers constituting water top header 1 is provided with inwardly-- compartmentsand each"of= said compare thereby presenting an enlarged cooling surface Within a given space and allowing such portion of each compartment to bend out- Wardl under excessiveinternal pressure.

2. ii a radiator, the combination of a plurality of Water compartments including a top header, a bottom header, and a plurality of Water tubes connecting said top and bottom headers and communicating therewith, each of said headers embodying a plurality 10 of inwardly dished Walls of curvilinear for- CARL McNEELY.
