RADIATOR FOR COOLINGj FLUIDS.

To all whom 'it may concern.'

Be it known that We, GEORGE I. ONIoNs and Gonrlunn ADoLPHsoN, both citizens of the United States, and residents of Bualo, in the county of Erie and State of New .York, have invented certain new and useful Improvements in Radiators for Cooling Fluids, of which the following is a specification. p.

yOur inventlon relates to heat-radiators, -of

,the ltype used in motor-vehicles for cooling the circulating fluid passing around the engine cylinder.

The primar object of our invention .is the production of a highly efl'icient tube heatradiator which can be more economically manufactured than-radiators of -a similar type now in use, and which provides in its construction for a more effective and durable connect-ion between the.4 air-tubes.'

Other objects are the provision of tubes which can be quickly and accurately assembl'e'd without the use of skilled labor and which, when' assembled, present an even front and rear surface; to provide combined strengthening and separating means at the ends `of the tubes; 'to provide the walls' of the tubes, at least in part, with. diagonal grooves, and to otherwise improve on heat- .through one end of one of the tubes.

radiators with a v'iew of reducing the cost of production while increasing its durability and efficiency.

lVith these objects in view, our invention consists in the construction, arrangement,'

and combination of parts to be hereinafter described and particularly pointed out'in the subjoined claims.

Fig. 2 is an enlarged horizontal section' taken through a` number of assembled tubes lying in thesame horizontal plane.

one end of a' tube showing a modified form of separator.

Referring now to the drawings in detail, similar letters of'reference refer to similar parts in the several figures.

The reference letter A designates the veasing of the radiator. having a dome or inletchamber B at its upper end, an outlet-chamber C at its lower end and air-chambers D at the sides. Within the space formed by said chambers are air-tubes 'E so arranged and separated that .spaces F are formed between them which serve as water-passages connecting the inlet-chamber with the outlet-chamber. The tubes are preferably arranged in horizontal rows with the centers of the tubes of alternate rows in-the same plane.

In order 'to form the water-passages F, suitable spacing-means must be employed at .the ends of the tubes, and for this purpose we provide each tube at opposite ends with spacing-devices or separators in the form of collars G which are slipped over the ends of the tubes with the collars of adjoining tubes in Contact. These collars, in addition to acting as separators'to form the water-passages F, also servie to strengthen the ends of the tubes where they are most. liable to damage.

In order to assure proper placement of the collarsuG- upon the ends of the tubes, they have inwardly directedflanges H-at their outerends lwhich bear against the edges ofthe tubes and serve as stops, so thatin placing the' collars on' 4the tubes, it is simply necessary to slip them onto the tubes until said tlanges strike the ends of the same. As the'tubes are allofexactly the same length, a perfectly even front and rear surface is thus obtained for the block of assembled tubes, without the exercise of any great vcare and without. the employment of skill-ed labor` -As the metal of which the .air-tubes are Y, formed is ,very thin, it is desirable 'that thel i fiangcs l-I extend bevond the innerv surfaces of the tubes` particularly owing to its being rather' difticult to form sharp angles on the collars with flanges extending only to the inner surfaces of the tubi-is. The portions of the flanges extending beyond the inner.' surfaces of the tubes'we recurve'or bend inward. as at I, and this greatly strengthens the tubes and prevents the walls of the latter being bent or forced away 'from the outer Moreover. it greatly minimizes the possibility for leakage, to

which radiators 'of this type are susceptible K cause a whirling motion of 'the air pass 4i5 are applied to the tubes, the latter are asand shape to lit into thecasing of the radi- 4ends of the water-passages between the when brought in contact with an object by collision or otherwise. A

The tubes herein shown are of rectangular formation in cross-section; and are formed of thin copper blanks J having several longitudinal rows of diagonally disposed grooves K, which are preferably arranged at an angle of `fortylive degrees to the longitudinal, and When said blank is bent on the dotted 'lines L, shown in'Fig. 8, to form the tube the grooves will be on three sides of the tubei 'i The grooves thus formed are on the insultil of the tubes and' as these grooves are stamped in the blank, they form ribs K1 on the outer sides of the tubes. The grooves ing through lthe tubes and also increase the interior surface area, thus aiding considerablyin cooling/ the rWater passing betweentHetubes. If desired, the tubes may be made hexagonal, octagonal, or given any other crosssectio'nal forni; the spacing-collars beijng, of course, of corresponding'formation The sizes of the Water-passages may be varied by using .collars of thicker o1' thinner metal, as may be desired; and the tubes may be arranged in any position relative to each other,.'so long as the Waterassage betweenV the tubes connect the inletc iarnber A of the radiator With theoutlet-chainber B thereof.

In Fig. 9,. We have shown the flanges .H onthe collar terminating Hush Wit-h the inner surface of the tube to which it is applied., but it will not be possible to. providethe collar with such sharp angles, withoutv an additional operation in the stamping of theV salue. In. some cases this modified form may be desirable., and when costof production is not considered, may be preferable to some'users, since it does not restrict the area of the openings through the tubes.

The collars may be made atight fit over the tubes, or they may be soldered to the tubes; and in either case, after the collars* sembled into block form of the desired size ator, and when so `assembled and4 held to gether. by suitable means with the exposed ends of the tubes in perfect alinement, the 4front and rear faces of the block of tubes are dipped into-molten solder so that they unite in a secureand Water-'tight manner.

From the foregoing description, it will be understood that the heated' Water enter'- in'g the radiator is deliveredl to, the upper open-ended tubes. Irfpassin through said -passages, the Water4 iscooledz y the cool air passing through said tubesi-and escapes throughthe lowernnds of said passages into the outlet-chamber, from which it is deliv ered to the motor.

Having thus described our invention, what we claim. isfl. A device of the character described having a plurality of assembled air-tubes; said tubes being united at their ends in a Watertight manner, each tube having spacing co1- lars fitting onto opposite-ends and contacting with the collars of adjoining tubos to -form water-passages between the tubes, said collars bein bent inward over the edges of the materia formingl the tube and recurved to enter the tube.

2. A device of the characterdescribed having a plurality of assembled air-tubes, each tube having spacingeollarsy fitting onto op posite ends and having their 'inner sides 1n contact with said tubeslar'id their outer sides in contact with the collars of adjoining tubes to forni Water passages? between the latter, each collar'- having the outer ends of its Walls bent inward to face'the edges of said tubes. 3. A device of the character described haw ing a plurality of assen'ibled airtubes, each tube having spacing-coilarsiitting onto opposite ends and contactingfwith the collars ward' over` the edges ofthe tubes and rovided 'Witha short return portion fitting into the tube, said return portions being shorter thanthe walls of said collars..

et. A radiator comprising a lurality of parallel tubes-each tube having its ends sun rounded by collars which engage'v'vith the eollars of adjacent tubes and each collar be- "ing provided at its outer end with anv 1n ternal reversely-folded fia-nge- Which turns around the' adjacent end of the respective tube and engages with the inner side of the same.

5. A radiator comprising ,a plurality of paralleli' tubes of hexagonal form in cross section, and hexagonal collars arranged on the outer sides of the'ends of each tube and enga 'n'gvvith their flatsides againstvcorrespon Vingiiat sides of the collars of adjacent tubes and eachcollarhaving its outer end provided with a ilangevvhich is' turned inwardly against the inner side of the respective tube.
