RADIATOR FOR AUTOMOBILES.

Specification of Letters Patent. P t-in ated Sept. 21, 1909.

Application filed August 30, 1907.

Serial No. 390,769.

To all whom it may concern:

Be it known that I, FRANK Tom), a citizen of the l nited States, residing at ()hicago in. the countyof Cook and State of Illinois, have invented certain new and useful improvements in Radiators for Automobiles, of which the following is a specification.

In practice dittie'ulty has heretofore been experieucet'l in repairing breakages and leaks, especially in an. interior and not easily accessible part of the radiator. Those falniliar with the art are aware that insome insta'nces the matter of repairing a slight leak in an inzwcessible part involves not only a considerable expense but also a distigurw tion of the radiator which makes it undesirable for further use.

'lhe object of the present invention is to provide a radiator that involves the con.- .-.truction unit system; or in other words a system enabling the radiator to be constructcd or reconstructed ofstruetural units having uniform characteristics.

An nn 'mrt'ant and peculiar feature of the t ment or unit which may happen to become disabled. I So far as I am aware this has never been done in actual practice; and the. desirability of it is self-evident.

The present invention involves among other things a construction of such a' nature that should one of the elemental units of the radiator become disabled upon the road or in a. loealitywhere repairs of the nature retpiired are impracticable a dummy can be substituted without impairing the operativeuess of the radiator and without any dismlvantage thereto with the exception of the diminution of its capacity to the extent of the ren'ioved active elemental unit.

'lhese being the objects, the invention consists in the features of novelty that are hereinafter described with reference to the accon'ipanying drawings, which are made a part of this spcciticatioi'i, and 111 which Figure 1 1s a front elevation of a radiator embodying the invention in its presleeve omitted. Fig. 5 is a perspective View of the top or cover of the header. Fig. (3 is a transverse section of a header. Fig. 7 is a perspective view of a bracing sleeve. Fig. 8 is a fragmentary vertical section of a radiator embodying the invention and showing the use of dummy headers. Fig. 9 is a perspective view of the middle portion of a dummy header. r

A represents the ei'tston'iary casing or-out-e5 side jacket of the radiator of an automobile. in the present. instance it has an upper or inlet chamber a into which the water is admitted from the jacket of the motor and an outlet chamber 1) from which the water, having been coiled escapes, returning to the jacket of the motor. The characteristic of the present invention resides'in the manner of assembling the parts going to make up the radiator. From the chamber a the .water passes in the first instance through a passage G into the so-called headers D of the radiator, whence the circulation takes place in the customarymanner. The passage C opens into one of the headers D and these headers are all coupled up in such manner that when the water enters one it passes freely from that one into the other, and soon in' series. These headers have interposed be--. tween them eiastie packinf s E, which are for bj the sole purpose of i'naking water tight joints between them and are tied together by bolts i whieh aredistiiosed longitudinally with respect to the direction of the operation of the machine. The passage C is so constructed that it enters into the bolt construct'ion forming a part of the connection between the several headers. In other words the passage C- is formed in a casting, a part of which receives the tie-bolts F. These tie-bolts are surrounded by elongated sleeves G which are perforated in order to permit the flow of water through them but otherwise perform the sole function of bracing the sides of the headers D in opposition to the resistance of the tie-bolts by which they are tied together.

As already intimated the purpose of this invention is to provide a separable and segregable structure, so that in the event of the destruction or disabling of any element ofthe radiator, the disabled element may be removed and I have therefore provided dummy elements H which may be Sl1bStl-',-'

tuted for the headers G. The efiect of this is that should the front section, become disabled and the operator being without asirnilai: section to replace it, he may replace it by the durnniy sections-"H which restores the radiator to the operative condition, but simply reduces its capacity to the extent of the removed section.

Another decided and very material advantage oi? the construction shown is that when a damaged section of the radiator requires to-be removed it can be done with facility, the radiator in its entirety being made up of a number of absolutely similar units, anyone which can be removed or l5 replaced with. facility. From the headers I) the" water passes downward tl'irough the radiating tubes 1 and into the lower headers D and thence to the outlet J. The lower headers are con- QOstructed and arranged precisely like the up or headers, and have similar accessories,

which bear the same reference letters as the accessories of the .upper headers, plus the f. prime mark Whatl claim as new is: i 1. In a radiator thecombination of a plurality of circulating tubes, each having.

at each of its ends, respectively, a headersection, means for forming tight oints between the header sectlons, upper and lower water chambers, tubes passingthrough the upper and lower header-sections, and a duits, header-sections communicating with into close contact with each other, perforated tubes disposed horizontally and passing through said header-sections, and in-let and out-let passages communicating with said horizontal conduits, "respectively.

4. In a radiator the combination of a plurality of vertical circulating tubes or condui'ts, header-sections with which the upper and lcwer-endsof said conduits communicote, respectively, an upper, or in let ohamher, a water jacket, iii-passage leading from the Water jacket, a perforated tube arranged within the headers at the. upperends of the conduits, a tie bolt adapted to draw the header-sections togetheigand 'dummy headere sections adapted to be inserted, in the place of disabled activeheader sections.
