' RADIATOR.

Specification of Letters Patent.

Patented Mar. 6, 1917.

Application filed October 23, 1915. Serial No. 57,457.

To all whom it may concern:

Be it known that I, JOHN.B. GABRIELSON, a subject of the King of Sweden, residing at the city of Jamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Radiators, of which the following, taken in connection with the accompanying drawings, is a specification.

The invention relates to radiators for motor driven vehicles, and the object of the improvement is to provide a radiator core construction in which the water ways are substantially unobstructed yet provision is made for alining and holding the different plates upon one another in spaced relation in assembling said plates so as to form zigzag or serpentine water ways which extend around crosswise air flues so that when the sheets are assembled together they may be dipped in a solder bath thereby uniting all the parts in perfect alinement and in the spaced relation required for the thinv sheet metal water ways; and the invention consists in the novel features and combinations hereinafter set forth and claimed.

In the drawings, Figure 1 is an elevation of the front end of an automobile showing a portion of the radiator core with the air flues therethrough. Fig. 2 is a perspective view of a portion of the air flues, the upper edge being shown in sectional perspective at line W in Fig. 3. Fig. 3 is an enlarged elevation of a portion of the front of the radiator core, a portion of said core being shown in vertical section at line Z Z in Fig. 4. Fig. 4 is a sectional view at line W W in Fig. 3. Fig. 5 is a sectional view at line Y Y in Fig. 3; and Fig. 6 is a sectional view at line X X in Fig. 3.

Like characters of reference refer to corresponding parts in the several views.

-The numeral 10 designates the radiator which is made the size desired for cooling the water in the motor. The numeral 11 designates the casing or hood for: the core 12, which casing has a reservoir 13 at the top of the core 12 and a reservoir 14 beneath the core 12 from which the water returns to the motor after passing through the water ways 15 of the radiator core from the 'top reservoir 13.

The core 12 of the radiator is made up of zigzag water ways 15, the opposite walls of which are formed by strips of sheet metal 16 which are bent in the serpentine or zigzag' shape shown, the edges 17 being attached to one another by dipping in a solder bath while the central portion from the top to the bottom of each metal sheet '16 isbent to first one side and then the other as hereinafter described, so as to form a water way 15 of substantially uniform volume throughout its entire course from the top to the bottom of the radiator, that is, one in which the side walls are substantially equally spaced from one another and are bent in the same serpentine form. 1

The shape or design of each pair of serpentine metal sheets consists of vertically flat spaced portions 18 for contacting surfaces of the adjacent sheets, said fiat vertical contact portions being connected by a double or reverse curve formed by the union of a convex and concave line, which is often called an ogee outline. The design gives a pleasing form to the air tubes and provides a strong bracing construction for the continuous sheet metal strips 16 which form the walls of the water ways and a plurality of which make up the core 12.

In order that the flat surfaces 18 may be continuous from the. front to the rear of the radiator core 12 and form a strong bracing support, it is apparent that the bent out or spaced central portion for the water way must be placed on alternate sides of said straight portions 18. In order to change from one flat contacting surface '18 to the full inner sidewise bend, said sidewise bend in each sheet metal strip must change from the straight strip of metal in which there is no sidewise bend to a full sidewise bend which is the full crosswise width of the water way. This is preferably accomplished gradually throughout the ogee bend; hence the side walls throughout the ogee bend would start with the full bend on one side and no bend on the other and gradually change to the opposite sidewise bend in l which the sheet of metal which had no sideother, each of the two strips forming a zigzag water Way having the teats so contacting as to hold said sheets in the spaced relation required for a water way of uni} form volume. It is apparent that the line of sidewise projecting teats 21 and 21 form centering or alining points in the assemblage of the strips 16 which hold said strips firmly in perfect alinement so that the entire core may be quickly and easily assembled and dipped in the solder bath, thereby making the contacting alinement permanent 1 by attaching said sheets firmly to one anthe teats 21 of said inner other.

. The inner plates 16 have contacting flat, top, bottom and intermediate surfaces and plates snugly nest one within the other, while the teats 21 of the outer plates 16 cooperate with the teats 21 and serve to hold the outer plates spaced from the inner plates as shown in Fig. 4.

I claim as new:

-1. In a radiator an inner pair of plates having top, bottom and intermediate flat contacting surfaces and shaped to .conjointly form air flues between said surfaces, said top, bottom and intermediate surfaces having interengaging concavo-convex teats, said teats being snugly nested one within the other respectively, and an outer pair of plates having top, bottom and intermediate flat surfaces registering with the corresponding surfaces of the inner plates and forming water passages with the latter, said fiat surfaces of the outer plates having concavo-convex teats registering with the corresponding teats of the inner plates, the convex faces of the teats of one outer plate being shaped and engaged in the concavities of the teats of the adjacent inner plate so as to space said last named plates, and the convex faces of the teats of the other nameaa inner plate being shaped and engaged in the concavities of the teats of the other outer plate so as to space said last named plates.

2. In a radiator, inner and outer-"spaced pairs of plates shaped to provide inner air flues and outer water passages, the inner pair of plates having'fiat contacting surfaces formed with concavo-convex teats snugly nested one within the other, the outer pair of plates having flat surfaces disposed opposite'the respective flat surfaces of 'the inner plates, and concavo-conver: teats formed on the flat surfaces of the outer plates and registering with-the correspond ing teats of the inner plates, the convex faces of the teats of one outer plate being engaged in the concavities of the teats of one of the inner plates and shaped to space said last named plates and the convex faces of the teats of the other inner plate being engaged in the concavities of the teats of the other outer plate and shaped to space said last named plates.

3. In a radiator, an inner pair of plates having top, bottom and intermediate flat contacting surfaces, and substan- 'tially S-shaped' connecting surfaces between the successive flat surfaces, an outer pair of plates having top, bottom and intermediate flat surfaces registering with the corresponding flat surfaces of the inner plates and substantially S-shaped connecting surfaces between the successive fiat surfaces of the outer plates which last named s-shaped parts register with parts to form water passages in conjunction therewith which water passages cause a retarded and serpentine flow of the water, the contacting surfaces of the inner pair of plates having teats snugly nested one within the other, and teats on the fiat surfaces of the outer plates cooperating with the teats of the .inner plates to maintain the outer plates in their said spaced relation to the inner pair of plates.

In testimony whereof I have afiixed my signature in the presence of two witnesses.
