RADIATOR.

To au whom t may concern. Be -it known that I, PRIMM R. Hiiwmorne, America, residing at Battle Creek, in the county of Calhoun and State of Michigan,

have invented a certain new and useful Radiator, of which the following lisa specifica.- tion, reference being companying drawing. t 1'0 This invention. relates to radiators de`- signed for-iisein connection with internal combustion motors, the object in view being to provide a radiator which will be economical to manufacti'ue, and efficient and economical in its operation. 1 A Jfurther object of the yinvention is to provide for 'a denite and regular path of circulation-.cfg the cooling medium throughout the entire;radiator structure, causing the through the radiator mathinjstream which is. constantly in motion, the directionpof travel. et the stream beinglar el late ally or vcrosswise with re speettot e direction ofthe draft or current ofv-.air passing'between thev sections of the .radiatorj'. ,Ac further obj ect' of Ajovide al radiator which the invention is 4to will eliminate the rination of pockets in various portions of .'ilgfqtbe.A structure, preventing the accumulation fof the cooling medium at any point throughfout thesystein, thus securing a uniform reduction in temperature of the cooling inediiun. l

"Afurther object is to arrange the cooling Y sections in such a way that the soldered4 'seams'for joints thereof are accessible at all times,.and, therefore, adapted to be repaired, without tearing.` down the radiator.

A further object of the invention is to provide a-radiator made up ofinterchan'ge lable parts oir-sections, so that it is possible i to rmnoue any part or section of the radiaj toi-,..ind to add to or subtract from lthe number of sections in accordance with the volunie of cooling medium to be handled, and A the horsepower of the motor in connection v with'whch, the radiatoris used. v:[t'is also possible,in case of accident or leakage of one oftheisections, to remove-the saine, which will lessen the eiiiiency of the radiator only inl proportionitothe surface of the section removed. l

.Afurther object is to produce a more rigid a citizen of the United States ofA :hereinafter described. had therein to the ac- .,as illustrated in Figs. v1, 2 and and substantial construction of radiator Specification of Letters Patent.

which will effectively guard against the injurious effects of internal pressure, and to provide means for lirmly clamping together the sections of the radiator with any desired pressure, the latter being limited vonly by the tensilestrength of the tie bolts or studs,

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts, as will be hereinafter more fully described,

pended.

In the drawings: Figure 1 is a horizontal section through one of the cooling sections of the radiator of this invention, showing the combined braces and baii'les in plan view. Fig. 2' is a vertical longitudinal section; through a pair of superimposed cooling sections. Fig. 3 is a vertical transverse section through the same. Fig. L is an enlarged vertical longitudinal section through a complete radiator, Ataken in line with the tie bolts or studs of two of the'hollow columns. Fig. 5 is a detail vertical section taken diametrically of a portion 'of one of the columns. 'Fig 6 is a detail vertical section,

showing the 'means for draining the raf diator.

The radiator contemplated in this invention comprises a `vertical series of hollow cooling sections l, 2, 3 and 4, the same being superimposed 4or arranged one above the other, as shown in Fig. 4, and being spaced at a suitable distance apart to allow acurrent of air to pass between the sections.

. Each section comprises a top sheet 5, and av bottom sheet- 6, said sheets being of sheet metal of light gage, the .top sheet having its marginal edges bent downwardly, as shown `at 7, while the marginal edges of the lower sheet 6 are bent around the out-turned bottoni edges of the top sheet, the seam or. joint extending around the entire margin of each cooling section being soldered to prevent leaka e.` f

Fac cooling section is internally braced,

3, by combined bracing and baffle strips, 8, each of which is illustrated as of L-shape incross section, as seen .in Fig. 2, said strips 8 eX- killustrated in thel accompanying drawings, and pointed out in therclaims hereunto ap-v tending transversely with relation to the direction ofthe current of air passing between the cooling seotionsas will hereinafter apf that the cooling medium passing from onev end of the cooling section to the otheris forced to take a circuitous path and to move back and forth across the raidiator and transversely of the direction of movement of the air current passing between the cooling sections.

The cooling sectionsare spaced at a suitable distance apart by lmeans of spacing` strips 9, which, it will be observed, extend transversely to vthe direction in which the strips S run. These strips 9 run in a fore and aft direction, or in other words, in lines parallel to the direction of movement of the current of air passing between tti cooling sections. Therefore, the cooling .nedium passing between the strips 8 is carried back and forth in planes transverse to the path traveled by the air current.v This results in more thoroughly subjecting the cooling medium to the cooling action of the air current, the cooling medium, such as water, being spread out in a broad thin sheet, during the progressive movement' thereof through each cooling section and through the several sections superimposed one above the other. In addition to the features hereinabove described, each cooling section is provided with openings 1() and 11 in alinement with eachother in the top and bottom sheets, as shown in Figs. 1 to =l,.inclusive, the said openings being adapted to receive the heads or sections of the columns now to be described.

Referring now to Fig. et, the cooling sections are shown'as connected to a pair of vertically extending hollow columns A and B, each olui'nncomprising a cap nozzle 12, and a base nozzle 13. Each column, between the top and bottom nozzles thereof, is provided' with a vertical series of heads 14 which are spaced apart by means of spacing rings 15. Two types ot these heads are employed in the series ot hollow columns.

V()ne type has an open center, while the other type has a closed center, lor in other words, 1s provlded with a horizontal partition 15 formed with a. central hole 16 to receivc one of the tie bolts or studs 17, by means ot which all parts of the hollow column are tied together and .caused to c lamp the cooling sections 1, 2, 3 and 4 tightly m place. Each column head or section is externally rabbeted at its top and bottom, as shown at 18, leaving a central body portion 19 which is of" just sufficient size to tit ,into one of the openings 10 and 11 ot the cooling section, the width of the central portion 2O of each head or section being the same as the distance between the top and bottom sheets 5 and 6 of each cool ingsection, as clearly shown in Fig. L1. Gaskets 2l in the form of rings of rubber or other suitable material are interposed between the'spacing rings 15 and the column heads or' sections, asshown in detail in Fig. 5, so as te form tight joints at such points, and each column head or section is provided with lateral openings 2 2 therein, extending all around the peripheral wall'of the section orhead, so as to allow for the circulation ot' the 'cooling medium between the cooling sections and the column sections. As shown in Fig. 4, the 'top column section or head, at the left hand side of the figure, is of the closed center type, and the column head or section, at the'right hand side, is of the open centertype. In the next lower cooling section, the relative arrangement of closed and open heads is reversed. That is to say, the closed head is at the right hand and the open head is at the left hand. This alternate arrangement of openand closed heads is preserved throughout the' entire series of cooling sections, the object lbeing to force the cooling mediumv to follow the direction indicated by the arrowsin Fig. el; that is to say, the cooling medium entering through the inlet E23 of the nozzle A is,A arrested by the partition 1'5" of the first column section or head met with,` and is forced through the openings 22 lengthwise of the top cooling section 1. The cooling medilnn `then passes 1n through the v,lateral openings QQ of the column head orsection'at the opposite end of the cooling section, and thence downwardly into the column section or head below. which is of the closed type, and, therefore, forces the water to pass in a reverse direction through-the next lower cooling section. This relative arrangement of parts is carried out throughout the entire series of sections, so that the water passes back and forth through all of thel sections, until it finally issues through the outlet 24 of the base nozzle 13. Under the preferred embodiment of the invention, each tie bolt or stud 'i7 is threaded at its lower end, as at Q5. and screwed into a threaded opening in.

the base nozzle, while the upper nd thereot' is threaded to receive a clamping nut 26. The cap nozzle A is also formed with a stuffing box 27, in which is placed packing Qt, and a gland 29 for compressing the packing around the tie bolt or stud 17, the gland being pressed inwardly by means of the nut 26 simultaneously with the operation of clamping all of the sections of the Leaders radiator together. ln order to provide for drainage of the radiator and prevent the freezing of the same, the central opening 16 in each column head or section of the closed r, vpe4 is slightly larger than the, external diameter of the tie bolt or stud ll', as shown in F ig. 6. Therefore, when the coolingmediem, such Water, at rest and the bottom connection of the radiator left open., the i iter will find way downwardly through the holloov col umns into the base nozzles 13 and outimrdly through the openings 24, into one of? which a threaded plug or stop PEO may be. ewed, shown at the right hand end ot l. is to the arrangement of the open and closed column heads or seelions. it will be' observed that all of the-coolsections; are identical, but in assembling the cooling sections, they are alternately turned end lor end. as shoivn in Fig. e. `which has the eliect or" bringing the closed and open sections of the column into the deed arrangement to effect the definite path circulation oi the cooling medium, as hereinabove described. if desired, a forced circulation et the cooling medium maj;l be obtained by the use oit a suitable force pump (not shown).` Such pump is not absolutely necessary, however, as it possible to use 4the ordinary thern'io-siphon system of circulation Withthe radiator hereinabove described. y

From foregoing description, it Will new be seen that a forced definite and regulA i path of circulation is provided for the if `ne n ed: n, and that it is carried in a stream "inv oli-gh the cooling sections, the direction of travel being back and forth, sversely and longitudinally of the :ling notions, the cooling medium, during ,-ortion o its being directed back *i n' transversely with respect to il movement of the draft or more quickly and efficiently ed to ay niiuimum, and the Ction ot temperatnre obtained .e entire body ot the cooling the cooling sections said sections may uer. thus enabling lthe tepairs may also out taking down the rae the fact that the soldered :tions areall at the insbe-re described allows large amount of cooli ff to the dr or' air, and i. a amount of eoolin passing between the cooling medium on account of the definite path of I movement of the thinstream passing through the sections ot the radiator. .Y I Y T he construction, hereinabove particularly described and illustrated in the drawings, also results in a more rigid andsubstantial construction of radiator, as the sheets of which the coolingsections are composed are thoroughly-braced both against internal and external pressure. b
