the art to which it appertains to make and use the same.

.My invention relates to so-called cellular types of radiators, suchas are extensively used in connection with automobilesemploying explosive engines as their motive power. The chief objects of the invention are high efficiency, simplicity of construction and small cost, all with. the use of a minimum amount of sheet metal; and to such ends, generally stated, the invention consists of the novel construction and combination of parts hereinafter described and defined in the claims. I

The improved radiator is illustrated in the accompanying drawings wherein like characters indicate like parts throughout the several views. Referring to the drawings Figure l is a diagrammatic view in front elevation showing a radiator designed in accordance with my invention;

Application filed December 20, 1915. Serial No. 67,780.

In Fig. 1, the radiator frame is indicated by the numeral *1, the upper water chamber of the radiator by the numeral 2 and the lower water chamber of the radiator by the numeral 3, which parts may 'be of well known or any suitable construction. f

The cellular core of the radiator is made up of a multiplicity of thin sheet metal (preferably of brass) tube forming plates that are bent into zigzag form and adapted to be put togetherin pairs to form zigzag water tubes, each of which tubes constitutes one unitand they are arranged to be put together to form the cellular core consisting of the above noted vertically extended zigzag Water tubes and intervening zigzag air cells or passages opening at front and rear en s. indicated by the numeral 4. In vertical cross section, the plates 4 follow zigzag lines forming adj acent surfaces at angles of 120 degrees, thus forming the alternated surfaces of zigzag cells or passages. The said tube-forming plates 4, at their front and rear edges are ofiset at 4*, so that they are brought closely together, and these oints are connected by solder, so that the water tubes 5 formed by the cooperating plates are closed at front and rear of the radiator.

Proper assembling of thetubes to thus form the cells requires accurate alinement or positioning of the tubes with the flat outer surfaces of the tube-forming plates, at least at front and rear of the core, in proper contact. To accomplish this alinement or proper accurate assembling of the units, various devices, such as independent or additional alining plates have been interposed between the units and provided with the proper lateral projections for engagement with the cell-forming .walls of the plates.

In my improved radiator, only the tubeforming plates are used, and the alining devices are formed. by partially severing, from p the said tube-forming plates, alining webs and giving the same the proper lateral projection for engagement with channels of the cell-forming walls of tube formingplat'es of This result may be accomplished in different ways, several of which are illustrated in the drawings.

In the preferred arrangement illustrated in Figs. 2. to 5, inclusive, the offset end por-- tions 4 of the plates 4 are made a little longer than would be otherwise required and The zigzag tube-forming plates are the outer portions 6, on the three sides of each air cell-forming channel, are slit at 6 (see Fig. 2), leaving the web-formin portions 5 connected to the respective p ates 4 onl at the flat surfaces 6 that are to en age wit the corresponding fiat surfaces 0 an adjacent unit or tube. The said web-forming portions 6 are then properly offset by bending the same 180 degrees (under which movement the un'slit portions at .6 will assembled, will, of course, be permanently united by solder, preferably applied at the front and rear edges of the tubes or units.

The construction illustrated in Fig. 6, up

to the point illustrated in Fig. 2 is identical with the first described construction, but in webs 7 correspond to the-web 6, is accomplished by pressing the same laterally, as indicated in the lower portion of Figs. 6' and 7, instead of turning the said webs by the swinging movement described in the first instance.

Fi s. 8 and 9 illustrate a construction like that 1llustrated in Figs. 6 and 7, except that the offset edge portions 4, in lieu of the slits 6*, have parallel pairs of slits 6' which partly sever alining webs 7 corresponding to the alining flanges 7, except that they are located slightly inward from the edges of the plates 4. r

' As is evident, by virtue of the construction above described, highly eflicient alining webs or devices are provided Without adding appreciably to the cost of manufacture of the tube-forming plates themselves and without requiring any intermediate spacing plates or elements additional to or distinct from'the said tube-forming plates. By the use of the said spacin webs pressed from and integral with the tu e-formin plates, the process of soldering is also simp ified, so that not only the amount of sheet metal or material, but also labor is reduced to a minimum, and at the same time, a superior cellular radiator core is produced.

Wh t I claim is:

1. cellular radiator made up of alternately bent zigzag plates united in parallel to form laterally spaced zigzag water tubes,

the said zigzag water tubes being assembled to form intervening air cells, and the said tube-forming plates havin at their edges, laterally pro ecting integra alining portions that engage and fit the cell-forming channels of adjacent tubes.

2. A cellular radiator made up of alternately bent zi zag plates united in parallel to form latera ly spaced zigzag water tubes, the said zigzag water tubes being assembled to form intervening air cells, the said tubeforming plates being united at the edges of the tubes and having, at their edges, laterally pressed alining webs that enga e and fit the cell-forming channels of a jacent tubes.

3. A cellular radiator made u of alter: nately bent zigzag plates united in parallel to form laterally spaced zigzag water tubes, the said zigzag water tubes belng assembled to form intervening air cells, the said tubeforming plates having their front and rear ed es pressed together and united with fluid tig it oints and formed with partially severed laterally pressed alining webs engageable with the cell-forming channels of ad acent tubes. this instance, the ofl'setting of the alining 4. A cellular radiator made u of alternately bent zi zag plates united in parallel to form latera ly spaced zigzag water tubes, the said zigzag water tubes being assembled to form intervening air cells, the said tubeforming plates, adjacent their edges, having alining webs severed therefrom at their sides but integral therewith at their ends, and laterally pressed to a form reverse to the surface from which they were cut, and adapted to engage the cell-forming channels of adj a- 'air cells, said plates at their edges being'slit and over-turned to form integral reversely bulged alining portions that engage with the cell-forming channelsof adjacent plates.

In testimony whereof I aflix my signature -in'presence of two witnesses.
