l `To all, 'whomvr may concern:

, vBe' it'lrnow'rn that I, LEON LozIANo, a citizeyn of France, and residing at Paris, France, have invented certain new and useful Improvements in Radiators, of which the following is a specification.

l Thisinvention relates to radiators'of the type lrnown as ribbed radiatorsf? which have ribs-located at intervals in the air passages and which are connected to the walls of the water ducts, so as to increase the radiating surface, and also to impart rigidity to the structure..

, ,such exclusive use.

y The invention is particularly adaptable Vfor use in automobiles, but is not limited to The objects I have inlview are to increase I the rigidity and strength of the radiator,

decrease the expense of manufacture and reduce the weight of theradiator, and, at the Sametime, increase its efliciency. These .and further objects will more fullyappear from the following specification and aci "plied to an automobile radiator. Fig. 2

In-the embodiment chosen for illustrationg; ehr plate has a straight and pal-allelfpertlo i of its longer sides, indicated-.at 6.' y each straight and .parallelrportiolh:s va

of the water duct. In the embodimefitchoseh for illustration, each plate' .isprovi-dedwith a fiange 8. The flangemaybe .made ystriking up the material atthefedgexo ,th i.p'lalte n the embodiment chosen for illustration, the portion 9 of the flange 8 which is conterminous with the straight and parallel portion 6 of the plate, is straight, and its free In other of uniform height throughout. The portion 10 of the flange which, in the embodiment chosen for illustrationfis'shown as cont-erminous withl the curved -or bent portion 7,l vis `of less'width or lheight thanthe portion 9,

of the flange. When the plates are piled to form a section, as shown in Fig. 7, openings 11 are disclosed between the plates, such openings being conterminous with the lower portions -10 of the flange. 'The height of the portions 9 of the flanges of the plates will determine the distance at which Vthe plates are spaced apart. The height of the lower portions 10 of the flange, will deterl mine the width of the openings 11. These flanges may be so low at the portion 10 that they are of negligible height, in which case the openings 11 will be of the maximum width, with a given spacing of the plates.

The plates 5, which constitute a section which, in theembodiment chosen for illustration, is as high as the radiator, are piled together as shown in Fig. 7, and `are suitably spaced. Each plate will rest upon the high portion 9 of the flanges of the plate below it. In addition to the flanges, each plate is provided with lips 12, adjacent to each en'd. These lips maybe conveniently formed by continuing the flanges 8 beyond the ends of the plates, as shown. but they are not necessarily so made. The' plates constituting a section are assembled, as

shown in Fig. 7, and sheets 13 are placed against each side -of the pile or bundle. These sheets 13 are preferably as wide as the length of the plates, and as long as the height of the pile. 'Ihey are preferably made of very thin brassorcopper, so that they will be pliable and, atthe same time, Will -not be corroded by the action of the Water. The sheets are placed in position against the sidesof the pile of plates, and engage with the edges of the plates 6. The edges of the-sheets lie under the lips 12. These latter lips are bent down so as to grasp the edge of the sheet, holding the latby a hammering or pressing operation so that vthey are ,forced tightly and closely against the edge of the sheets. In order to assist in holding the plates in proper position to apply the sheets, the device illustr-ated in Fig. 8 may be employed. 'This device consists of a `comb 19, of any suitable material and of such a shape that the interstices between the fingers of the comb are spaced the same as the plates Will be inv the finished section.

After the sheets 13 are 1n place and secured by the lips, Vthey are forced into close -engagement with the side edges of the plates 5. AnyV suitable tool or mode of operation such engagement. As an additionalrefinement of the invention,"I prefer to force the I may be used 'for forcing these sheets into 'l materialy of the sheets into the spaces 1.1,

so that the materialis distorted at these places and is formed inthe shape of corrubined, the juxtaposed sheets 13, ofopposing sections, will define the water ducts. In other Words,onehalf of each Water duct is, formed of the curved or bent depression in the side of the section, said depression extending throughoutthe height of the sectio`n. Solder is now applied to the sections, adjacent to the edges of the 'sheets 13 and the ends of the plates 5, to hold the parts together. A convenient Way of doing' this is to dip one face of the massed sections '-f into a bath of solder to such a depth that the solder will enter the spaces between the contiguous ,lips 12, and will also enterA the spaces .between vthe abutting straight portion 6,]at 15, as shownin Fig. 3. The other falce of the mass ofsections may then have solderapplied to it inthe same manner. The radiator is now complete, with tbe addition of the top and bottom manifolds18. As the water willcome in contact witlrthe upper and lower plates of the sections, these plates 16 are best made of brass or copper. In order to produce a proper finish and to prevent the water from leaking out ofthe manifolds into the air passages, #the upper and lower edges of the sheets 13 are bent over against the upper and lower plates ,16, as indicated at 17 (Fig. 10).

Wy improved radiator is exceedingly strong, remarkablyA durable, 'very eflicient,

and extremely cheap to manufacture. The

greater portion of it is constituted of 4the are heid in'position and may be distorted into close and intimate contact with the edges of the plates 5. The degree of contact between the sheets vand plates determines the thermal eiiiciency of the radiator, therefore, this close contact of the sheets and rectangulary shape,

plates produces a high thermal etfciency. The lips 12 also permit the use of very thin sheets 13, because they hold them in place while the elements of the sections are being assembled, and also hold them in place when the several sections are being held togetherv during the soldering operation. Vhile the radiator is in use, any pressure of water Within the water ducts will tend to force the sheets into more intimate contact with the edges of the plates.

I regard the corrugation of the sheets as important but not essential. It greatly increases the strength of the radiator, causing more intimate contact between the sheets and edges of the plates and increases the thermal eiiicienc'y, as the air can come into direct contact with the sheets. I regard the flanges of the plates as important, but not necessary, as the plates may be held in properly spaced position by means of the comb 19 during the assembling of the parts, consequently, the flanges may' beomitted if desired. It is also not necessary to make them of the shape shown, as the portions 10, of the flanges, may be `omitted, as well as the portions 9. But the lips 12 must necessarily remain.

While I have described my invention as applied in connection with radiators for automobiles, it is apparent that it may be utilized for other purposes,-not only for cooling water, by the passage of air through the air passages, but for heating air, bythe use of hotfwater. The radiator may be used also fdr other purposes, such as a condenser.

v In accordance with the provisions of the patent statutes, I have described the principle of my invention, together with the apparatus whih I now consider to represent the best embodiment thereof; but I desire to have it understood that the apparatus shown is merely illustrative and that the invention can be carried out in other Ways.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is :a
