RADIATOR CONSTRUCTION.

To all whom it may concern Be it known that I, ALEXANDER W. FIN- LAYSON, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Radiator Construction, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to radiators and refers more particularly to a radiator construction such as adapted to the cooling systems of automobile engines, although the invention in its broader aspects is not necessarily limited to the particular use mentioned.

Among the objects of the invention are to provide a construction which can be built up of a plurality of independently formed sections, preferably cast from aluminum or like material; to provide a construction in which access can [be had to any of the sections independent of the other sections; to so construct and arrange the parts that one or more of the units can be closed off from the cooling system so as to permit of varying the amount of radiating surface employed; to provide a construction in which the water in passing through the system is compelled to baffle back and forth in such a manner as to greatly increase the efliciency of the radiator; to provide a construction which has greater rigidity than radiator constructions now in use and which can be economically manufactured and assembled; and in general to provide an improved and simplified radiator construction of the character above referred to.

The invention also resides in such details of construction and arrangements and combinations of parts as will more fully herein- Fig. 4c is a plan view of one of the center units Specification of Letters Patent. 1 Patented July 29, 1919.

Application filed July 5, 1917. Serial No. 178,560. v

Fig. 5 is a plan view of one ofthe end units;

Fig. 6 is a front elevational view partly in section of the lower header;

Fig. 7 is a view of the upper header similar to Fig. 6;

Fig. 8 is a top plan view of the upper header; 7

Figs. 9 and 10 are detail views of one of the tank plugs.

Describing in detail the particular construction shown in the drawings, and re-. ferring first to the general assembly, A designates an automobile radiator having the usual open panel B, within the center portion of which there is exposed the cooling surface C. The cooling surfaceis built up of a plurality of independent center sections D, and end or side sections E, the particular construction of which sections is shown in detail in Figs. 2 and 3. At their upper ends these sections are connected into an upper header F and at their lower ends into a lower header or tank G. The latter is provided with the usual pipe connection H, while the upper header has in addition to the pipe connection I, the usual filler opening I.

In the operation of the radiator the cool- 'ing fluid is inserted through the filler opening and flows from one header to the other through the various radiator sections and then from the pipe connection to the jacket of the engine or other member to be cooled.

Describing now in detail the construction of the units and their assembly with rela-' ton to the headers, it will be noticed in Fig. 2 that the center units are formed with a main vertical portion J having laterally extending side flanges J and J these flanges being spaced apart a sufficient distance to receive the projecting flanges of the next adjacent section, as shown in Fig. 2, and to also leave the necessary air spaces through which the air can flow over the cooling surfaces formed by the walls of the flanged portions. In order to produce a more efficient cooling action, each of the flanged portions is provided with a sheet-metal baflle plate K saidflanged portions being cast around the baflie plates. In theformation of the unit, these baffle plates are mounted upona hollow rod L which also forms a spacer rod to hold the plates in proper spaced relation when the section'is oast; Near their outer ends the baffie plates are provided with passages L L and L, the arrangement of par-ts being such that asthe water passes from the main upright part J, it is compolled by the baffle plate to flow transversely throughout the length of the flange, first on one side of the baffle plate and then returning on the other side in order to reach the next part of the main vertical portion J.

The construction of the end units E and E is similar" to that of the center units eX- cept that one of the flanges J and J 2 is omitted and the end of the baflle plate similarly received in a short recess J At their upper and lower ends the main parts J of the sections are enlarged and internally threaded at M and M respectively to receive the cooling section connecting nipples N. These nipples have an enlarged head N which is drawn tightly against the seats N in the headers. Thus when the main upright portion J of the section is brought into registration with the seats N in the upper and lower headers and the connecting nipples screwed into the threaded portions M and M, the unit will be locked tightly to the headers and will have internal communication to the headers through the openings N in the connecting nipples. To fa-.

cilitate the assembly and also the repair or replacement of any section the upper header is provided with a series of enlarged threaded openings 0 in registration with its seats N these openings being of suflicient size to permit the insertion of the connecting nipple through the opening, whilethe lower header G is provided with a similar set of threaded openings 0' through which the connecting nipples for fastenin the lower ends of the cooling sections can lie inserted.

The threaded openings 0 and O are closedby suitable tank plugs 0 these plugs preferably having a wrench-receiving portion 0 by which they can be screwed into 1 orout of the threaded openings O and O.

that the flanges J and J are of reduced Not onl'y"does this arrangement of the connecting nipple facilitate the assembly and independent repair or renewal of the units, but it also permits of the closing off of any section or sections from the cooling system by simply substituting for the usual connecting nipple N a nipple N having a closed head, that is, one in which the passage N is omitted. It is therefore possible to regu-i late the amount of cooling surface by simply'sub'stituting onetype of nipple for the other and also in case of injury to one of the'sections, that particular section can be cut out of the system by putting in the closed end connecting nipple. The particular shape of the units is shown in the top plan views, Figs. 4 and 5, wherein it is seen duction in the width of the rear portion in view of the enlargement of the end portions of the members J.

From the above description it will be apparent that a radiator constructed in accordance with my invention can be cast from aluminum or other desired material and that even in the assembled arrangement the sections remain independent, that is, they can be independently detached for repair or renewal and that any desired section or sections can be easily cut out from the cooling system. Various changes, however, in the details of construction and arrangements and combinations of part-s can be made within the scope of my invention.

What I claim as my invention is:

1. In a radiator, a unit comprising an integral cast metallic member having a central longitudinally extending portion formed with a series of enlargements therein and sheet-metal baflle plates respectively located within said enlargements.

2. In a radiator, a unit comprising an integral central longitudinally extending portion having a series of enlargements therein, balfle plates located respectively withinsaid enlargements and a member arranged within the central portion of said unit and connecting said battles in a fixed relation. V

3. A radiator, comprising top and bottom headers, a plurality of units connecting said headers having open ends registering with openings in said headers, nipples extending through said openin s and detachably engaging the ends of sald units, the'lower face of the lower header and the top face of the upper header being ap'ertured in registration with said units giving access through the headers to said nipples whereby 'said units are independently detachable. I i 4.. A radiator, comprising topand bottom headers, a plurality of units connecting said headers and having open threaded ends regunits to give access" through said headers to said nipples to permit of separately detaching said units from said headers.

In testimony whereof I afiix my signature.
