An'rbmoBILn-mnwroa Specification of Applicatitn flfe'd May 17,

To all whom it may cmwem:

Be it known that I, Kmb mnm M. BOB- Imi'i, citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Automobile ltediw tors, of which the following is a specification.

My invention relates to fllild ooolin apparatiis 0r eendensers and particular y to radieters for use in connection with exlosive engines and it is especially adapted for automobile use. The invention, however is not limited to such use, but may be emp o'yed'in connection with refrigerating apparatus or may be employed as a radiator for heating purposes.

The olfij'ect of the invention is to sim lify the strnctiire as Well as the means and mode of e eietion 6f deviees whereby they Will net trul "be ehe'apened in 'eoastruetien, but will be more 'e'fiieieht and economical in operation and unlikely to out of repair.

intermediate the sueceedin conduits of the reuiet'ea Fig. 9 is a detail seetienel view (if two radiator conduits with the interposed spacer or fin plate. Fig. 10 and Fig. 11 are detail Views of modifications of the radiator members.

Like parts are indicated by similar Charaetei's of reference throughout the several views.

The radiator forming the subject matter hereof is of the cellular type, presenting a front surface of pleasing appearance divi ed into a multitude of rectangular cells of substantially equal proportion. The particular shape of the Cell is optional end may be varied at will. In constructing the radiator there is employed a main frame having in the upper portion thereof a receiving chamher 1 and in its lower portion a di pensing chamber 2 connected with the receiving chamber by a plurality of conduits through whieh the water passes from the chamber '1 to the chamber 2. These -conduits ma be either continuous from one chamber to' the other, shown in Fig. 1 of the drawing, or they may be short lengths and arranged in tiers separated by intermediate Water spaces or auxiliary chambers common to all the eonduits of the tier in the manner well known in radiator constructions. The length of the conduits is immaterial so far as this particular construction is concerned andma'y be proportioned to 'agi'ee with the condition and the degree f heat to be overcome. The conduits are formed by arranging a plurality of similar members side by side but separated one from the other to form intermediate said members Water spaces er passages. The members are arranged in pairs and each pair constitutes a unit. These units are then arranged side by side to inclose, intermediate the sneceed= ing units,' air spaces end the units are com nec'tfed one to the other into an integral strilcture.

The rsdietor members are seen formed freme single sheet or stri of material cut and bent into the forth as illustrated in the di'atviifgs and hereinafter described. These iadiator members are identical in construeby side and joined one to the other by soldering, welding or by any other method to form a single integral or unitar structure. The members may be made 0 any length .and any number of units may be joined together, thereby permitting radiators of any desired size or proportion to be readily construpted. Each of the radiator members comprises a plate or Wall portion 3 oflset longitudinally as at 44 to form a longitudinally disposed shallow channel 5. The opposite edges of this plate or wall 3 are bent into laterally projecting flanges. One of these flanges is serrated or notched to form a series of tongues or independent fingers 6 while the other flange of the plate or wall is perforated to form a plurality of spaced laterally projecting fingers or bars 7 which, as shown in the drawings, are preferably connected at their extremities one with the other by a con tinuous bar or strip formed integral therewith, as indicated at 8. The connected space bars or fingers 7 form a latticed or ladder like structure. As shown in the drawing, the transverse fingers or bars 7 are preferably U shaped in cross section. This gives the structure a more finished appearance and renders the bars or' fingers more stanoh and stiff. The members thus described are formed from a single blank, as shown in Fig. 7. This blank. is notched or recessed along one edge to form the tongues 6. These tongues, of course, during the formation of the member are bent laterally to a plane substantially perpendicular to that of the main wall portion 3. The main or wall portion 3 is bent or'oflset, as indicated in Fig. 7, to form the offsets or edges 4-4 of the channel 5. Adjacent to its opposite edge the blank is provided with a series of substantially H shaped incisions alined one with the other. 1 TheseH shaped incisions are separated one from the other by intermediate uncut ortions of the blank. The flaps 9, formed by the H shaped incisions, are bent to positions perpendicular to the planes of the blank to form the'sides of the U shaped or channeled fingers or bars 7 the face or front of which is formed by the uncut portion of the blank intermediate the succeeding incision. Not only are the flaps 9 bent to positions perpendicular to the plane of theblank, but the uncut portions intermediate the incisions, forming the face of the bar 7 are also bent laterally and the extreme uncut marginal portion of the blank, indicated at 8, is bent to position perpendicular to the plane of the finger 7 and parallel with the body of the blank, as shown in detail in Figs. 2 and 3. In lieu of the H shaped incisions in the blank said incisions may be formed substantially U shaped with all the excess of material forming the flaps upon one side of the transverse incision. This single fia-p,.being bent at r ght ang s, wi produce a finger or bar having an L shaped cross sectional form, as shown in detail in Fig. 11. This is a mere detail of construction and does not change the function of the parts. The radiator members having thus been formed, as shown in detail in Figs. 2 and 3, the succeeding members are-reversed in relation one with the other and are placed together with their hollow or channeled sides adjacent and in registry. In this position the tongues 6 of one member will extend laterally beyond the plane of the other member and will overhang the spaces intermediate the succeeding transverse bars or fingers 7 of the adjacent members. The rela tion of the parts at this stage is shown in plan view at the left in Fig. 4'. The fingers 6 are then struck down through the openings intermediate the bars or fingers7 to clench the fingers of each member around the edge of the adjacent member. This relation of the tongue 6 and the fingers or bars 7 is best shown in Fig. 5 and the clenching or iiiclosure of the edge of one member within the tongue of the other member is best shown in detail in Fig. 6. The tongues of each member are bent over the edge of the adjacent member which secures said members into pairs, each pair forming a unit. The

registering channels 5 of the adjacent members constituting each unit forms intermediate said members the water space or conduit. This is the water space or conduit which, in the finished product, forms the means of communication between the chambers l and 2. The unit thus formed comprises the conduit or parallel wall portions aving oppositely extending open or ladder like flanges projecting-in opposite directions from opposite edges. These units, each constituting a pair of members, are thenarranged side .by side with theladder like or open flanges of each unit contacting with the adjacent units on either side. The series of units is extended to form the structure of the desired proportions. The units, having been thus assembled, are held in contact one with the other and are united by solder ing, welding, sweating, or preferably by a closed seam throughout the length of the conduit. The open orladder like flanges of succeeding units, 'which are assembled with thetransverse bars or, fingers of such flanges in alinement or in registry ,one with the other, form a latticed or cellular front of pleasing appearance; The inward extending flanges 9 of the fingers or bars 7 give to sald bars a massive appearance and serve to strengthen and stiifen the structure. The fingers or bars 7 being substantially equal in width to the thickness of the vertical seams formed by the juncture of the marginal bar 8 of one unit with the overlapped seam of the succeeding unit and the transverse fingers or bars of one unit being arranged in alinement with the succeeding unit forms a transverse barred structure of uniform appearance. The structure, as thus far described, forms a complete radiator within itself having, however, intermediate succeeding conduits, air spaces of considerable extent. It is desirable in actual practice to break this air space up into a plurality of compartments or channels. To accomplish this and to provide additional radiating space with which the air comes in contact, there are preferably provided intermediate succeeding conduits independent corrugated fin plates 10, as shown in detail in Figs. 8 and 9. In these figures the intermediate fin plates comprise a continuous plate bent upon itself through a zig zag formation and inserted between the succeeding conduits. This zig zag plate not only serves to break up the large air space into separate compartments or channels and afi'ords additional radiating surface, but it also forms an intermediate bracing member which tends to support the lateral walls of the conduit. The particular shape of this intermediate fin plate is not essential as it is obvious that many other forms of plate will readily occur to any person skilled in the art. It is to be understood that in finishing the core the open or ladder like flanges are removed from the terminal units.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable but which obviously is susceptible of modification in its form, proportion, detail construction, or arrangement of arts Without departing from the princip e involved or sacrificing any of its advantages.

While in order to comply with the statute the invention has been described in language more or less specific as to certain structural features, it is to be understood that the invention is not limited to any specific details but that the means and construction herein described comprise but one mode of putting the invention into effect and the invention is therefore claimed broadly in any of its possible forms or modifications within the scope of the appended claims.

Having thus described my invention, I claim:

1. A radiator member comprising a plate having oppositely disposed laterally projectin flanges at its opposite edges, one of said anges being serrated to form a plurality of tongues and the other flange being perforated, substantially as specified.

2. A radiator including a plurality, o members each comprising a plate having a laterally disposed serrated flange on one lineal edge and an oppositely disposed perforated flange upon the opposite lineal edge, said members being arranged in pairs with the tongues of the serrated flange of each member projecting through the perforations of the perforated flange of the other member and clenched about the edge of the opposing.

plate of the pair.

3. A radiator including a plurality of members each comprisin a plate having on each lineal edge thereo a series of oppositely laterally disposed spaced projections, the projections upon one edge being staggered or offset in relation with those of the opposite edge, said members being arranged in pairs to form conduits with the projections of one member clenched about the edge of the other member intermediate the spaced projections thereof.

4. A radiator including a plurality of conduits, each conduit comprising two plates arranged side by side to form an intermediate water passage, laterally disposed integral projections on each of the plates forming' transverse space bars intermediate succeeding conduits dividing the intermediate space into cellular formation, and a plurality of integral tongues on each plate on gaging about the edge of the opposing plate intermediate said space bars.

In testimony whereof, I have hereunto set my hand this 30th da of A ril, A. D. 1915.

KINDER AN BOBLETT.
