RADIATOR.

To all whom it may concern.-

lle it known that I, Fnrrz JoHNsoN, a citizen of the United States, residing at Fountain, in the county of El Paso and State of Colorado, have invented new and useful Improvements in Radiators, of which the following is a specification.

This invention relates to radiators for motor vehicles, in general, as well as other vehicles, the main object in view being to produce a radiator in which leaks may easily be repaired without requiring the taking down of the entire core of the radiator.

The improved radiator is of such construction that any one of the vertically extending water tubes may be removed and reinserted without disturbing any of the other water tubes. This renders it a comparatively easy matter to make thorough and lasting repairs without requiring skilled labor.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts, as herein described, illustrated and claimed.

In the accompanying drawing:

Figure 1 is a front elevation of the improved radiator.

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

Fig. 3 is a vertical transverse section thereof.

Fig. d is a detached perspective view of one of the water tubes.

Fig. 5 is an enlarged fragmentary section through one of the end joints of a tube and header.

Fig. 6 is a fragmentary perspective View of one corner of the radiator with the adja cent side plate removed.

Fig. 7 is a fragmentary perspective view of one of the side plates.

The improved radiator comprises an upper header 1 and a lower header 2, side plates 3 and a core consisting of a plurality of vertically extending water tubes 4 which communicate at their upper and lower extremities with the top and bottom header 1 and 2.

To the above end, the bottom plate 5 of the top header and the top plate 6 of the bottom header are formed with parallel elongated punched or flanged openings or couplings 7 each of said openings being arranged between flanges 8 which, when the Specification of Letters Patent.

tubes are combined therewith, are embraced by the walls of the adjacent extremities of the water tubes. There are end openings 8 at the ends of the flanges S. The couplings 7 are closed at their ends, and these couplings are adapted to be slid between the flanges 8, through the openings 8, when the tubes are moved horizontally.

Each watertube extends in a vertical direction between the top and bottom headers and is formed to provide a vertical straight continuous and unbroken water channel 9. In order to give a honeycombed appearance to the radiator and also increase the water cooling efficiency thereof, each of the water tubes is provided at intervals throughout the height thereof with pairs of oppositely extending wings 10 which are perpendicular to the tube and arranged so that the wings of one tube are in horizontal alinement with the corresponding wings of the adjacent water tube. The wings are of hollow or double formation so that as the water circulates through the vertical portions of the water tubes it also finds its way into and out of the tubular wing portions thereof. The wing portionsare, of course, subjected to the air passing through the core of the radiator as well as the walls of the tubes themselves. As each vertical water tube has a separate and independent connection with the top and bottom headers and no connection with the other tubes, at its opposite sides, it will be seen that any desired tube which has sprung a leak may be removed from the radiator without disturbing any of the other tubes. When restored to place, it is only necessary to solder the upper and lower extremity of the reinserted water tube. As will be seen from Fig. 3 the closed ends of the flan ed couplings 7 close the open ends of the flanges 8. These. parts are soldered together to make a water-tight joint. \Vhen a water tube is removed, it may be repaired at the greatest convenience.

Extending upwardly from the opposite ends of the bottom header of the radiator are side plate attaching flanges 11, formed with bolt receiving holes 12. Other corresponding flanges 13 extend downwardly from the opposite ends of the top header and are likewise formed with bolt receiving holes 14. The side plates 15 are provided fasten the side plate to said top and bottom flanges just described. Each side plate is formed at the front and rear thereof with inwardly extending flanges 19 and 20 to improve the appearance of the radiator casing and provide rests for the engine covering hood, in automobile practice, and each of the side plates is further provided with a' 1 ing lugs as shown in Fig. 1 of the drawings and in others of which the radiator is simply bolted to the frame or chassis of the vehicle. The shape of the top of the radiator may also be varied to suit difierent manufacturers.

I claim: In a radiator, top and bottom headers said headers being provided upon their adjacent sides with couplings which extend in-.

wardly toward each other said couplings being elongated and having their ends closed, and a plurality of vertical tubes adapted to be arranged between the headers, said tubes being provided at their opposite ends with upwardly and downwardly extending pairs of spaced flanges, said. pairs of flanges being elongated and adapted for the reception therebetween of the elongated couplings, said flanges having openings at their ends so that the tubes may be inserted in place by a substantial horizontal movement with relation to the headers.

In testimony whereof I aflix my signature.

FRITZ JOHNSON.
