sesses a large capacity for the circulationv of i the cooling water, and effects a thorough cooling of' such water. The invention further comprises novel and eflicient means, for removing any damaged section of the radiator without.distal-tong the remaining sec tions.

In the accompanying drawing:

Figure l, is a perspective view of an automobile radiator embodying my invention',

Fig. 3, a horizontal section on line 3-3 Fig. 2 with the tlanges of the front plates partly broke-1i away;

A Fig. 4,' a vertical cross section on line 4 4 Fiv. 3;

Fig. 5, a perspective view of oneof the de tachable cooling units, and

Fig. 6 an enlarged. cross section through The radiator, as shown, isof the socalled torpedo type, being composed of two wings, that join at an acute angle. It comprises essentiall a pair 'of converging upper water cham rs 2 having o en bottoms, and a pair of corresponding y arranged lower water chambers 3 having open. tops. At Vthe rear ends-the two chambers 2, 3 of each wing abut against a common back plate A, while at their forward en'ds all the four chambers abut against a common upright member 5, the whole forming a frame.

Above this frame there is mounted a hood 6 l that spans both of the wings and is furnished with a filling nozzle 7.

Between the water chambers 2, 3 of each wing are interposed a i,plurality of cooling units each composed o a front late 8, a rear plate 9, and a plurality of tu es 10, set into said plates, and adapted for the passage of thoP cooling, air. The front plates 8 are considerably longer than the rear plates 9 (Fig. 5), and abut'at their forward edges against the upright member 5, while the rear plates 9 of one wing will at their forward edges abut against t e forward 'edges of the other wing. In this way, there will ,be formed at the nose of the apparatus, an additional upright water chamber 11, which is devoid of i111 air tubes so as to retain its maximum capacity. This upright water chamber 'l1 communicates at its u per end with the converging front ends of t e u per water chambers 2, at its lower end wit the converging front ends of the lower water chambers 3 and at its inner end with the several l units' constituting the air-cooled members 8, 9, 10. The hot water from the motor cylinders is admitted to the top of chamber 11 or to either one of' the upper chambers 2)& y inlet nozzle 12, and is withdrawn from either one of the lower chambers 3 by an outlet nozzle 13. In this way a circulation will take place, part of the water passing through, to t e the cooling units to be here subjected action of the air pipes, while part ofthe i 'water will flow through the u right chamber 1l, to be here cooled by the raft or cooling air currents induced bythe motion of machine through space, the water being also4 free to flow directly between the upright chamber and the cooling units.

y Thus it will be seen that the capacity of the radiator is large relatively to its size,l while all of the' circulating water will be thoroughlycooled.

The several cooling units are made removable from each other so that'any one that may have become defective through collision or otherwise, may be replaced without disf turbing the remaining perfect unita To this effect, the front plates 8, are provided with horizontal rearwardly extending flan s 14, while the rear plates 9 are provide with horizontal forwardly extending flanges 15, the flan es 14 with the construction shown, protruding beyond the ianges 15.'

lVhen the several units are fitted within the frame, the two flanges 14 of two adjoining units will overlie each other, as will 'also the flanges 15. By now soldering the overlying flanges together, the units will be connected in a water tight manner,'the flanges furn'ishin an ample surface for the rece tion of t e so1der.When any one of e units is to be replaced, thesolder is removed by the application of a solderingl iron.

Though I have shown a. number of coolin units to be incorporated into each wing o the radiator, e sin 1e unit may be so emplayed, Whenever t e removable feature of the cooling members is not desired.

I claim: l

A n automobile radiator composed of u pair of converging upper water chambersfa:

p air of 'convergm ower water chambers, and cooling mem ers' interposed between said chambers, each cooling member being .formed of a rear plate, a front plate proj ecting a distance beyond the rear plate, and a plurality of air tubes set into the plates the forwardly projecting ends of the front pietes forming an u right water chamber at the 'nose-ofthe ra infor.
