JULIAN P. LYON, F DETROIT, MICHIGAN.

RADIATOR.

Application tiled December 20, 1913.

Ylie it lmown that 1. JI'LIAN P. LYON, a eitixen oti the l'nited States of America, residing at Detroit. in the eounty of Wayne and State of Miehigan. hare invented certain new and useful improvements in Radiators. ot whith the 'following is a specitieation, retlrenee beiner had therein to the accompanying drawings.

My invention relates to radiators and more inlrtieularly to radiators employed in eonnertion with explosion engines.

The invention has amongv the objeets thereof to provide an elieient and durable strueture; to provide sueh a structure that may be easil) and eheaply manufactured; to provide a eonstruetion in whieh the cooling; etlirieney is materiali)l inereased over radiators now in general use: to eliminate to a material extent the coating ot' solder on the surt'aees exposed to the air eireulating*r through the radiator: to provide a strneture in whieh the water tubes are free, from soldered joints: intermediate the sidesl ot' the radiator: and further to provide a diamine. lsimple and ellieient water tube.

(ither olyieets of the intention will more fully hereinafter appear.

"he invention resides in the peeuliar ('onstruetion. arimrgements and eombinations ot parts, as will more fully hereinafter appear and as pxutivularly pointed out in the rlaims.

l'n the draw'ingsM-lfigure l is a pei-speet'ive view ot' a portion of a radiator embodying the intention: Vig. 2 is a fragmentary vin-tieni seetion ol. the strut-ture shown in Fig, E 1 Vig. I is a plan view ot' one of the,

"iig", l is :i seltion ou the line .www of f: Vig'. 5 is a perspeetive view of one of this. and liff. H is an enlarged fragmentarv eiioual view.

iieierrngg to the one embodiment ot the intention .shown in the drawings. A\ designa tile inner plate of one header of the ramaflor and B the inner plate of the other header.

t' are a plurality ot spared water tubes havungY their top and bottom edges eonnerted respeetirely to the members A\ and B. as will more i'uily hereinafter appear. "the tubes t are eul'h formed from a piero ot liat metal l'olded upon itself to form a fiat tube. the bend ll #losing one edge of the tube while the free ends E F are preferably return bent and preseed together to close the Specieation of Letters Patent.

opposite edge. One end of each tube is inserted through a slot G in the member A and the opposite end of the tube is similarly engaged with the member B. The ends of -the tubes are suitably Connected to the headers preferably by bending out the marginal edges H I that project through the header plates. and then closing the joint; between the plates and the tube by solder.

Arranged between the tubes are a series of spaced tins J. each of whieh is composed ot a plurality of strips l( that tit between adjaeent tubes. ,Preferably the tubes C are ot' a length to extend from the top header to the bottom header` and ot a width to eX- tend from front to haelt ot' thel radiator. I (ind it desirable to form the tins J eaeh ot a single piet-e ot' metal preferably of a width to extend from front to bark of the radiator and ot' a length to extend eompletely from end to end ot the radiator, The metal iS slit to form the strips K and preferably the members l( at their front ends are integral with a eonneeting seetion L whieh is interlorked with the t'ront edges of the tubes as by providingr slots al in the front edges of the tubes whieh receive the eonneetin;r portions. the eorresponding slots in adjaeent tubes being in horizontal alinement. In order to strenuthen the portion L the latter is preferably bent downward and then return bent so as to form the section L of several plies ot metal. This arrangement not only adds strength to the fin but also, since the forward edge of the tube is composed of several plies of metal. f "i ves the radiator the anpearanee of ay eomparatively heavy structure. I `urthermore the eomparatively heavy interenqaging portions ot' the tube and the fin will permit the fin of the radiator to stand a eonsiderable thrust, w ithout damaging' the parts.

The sides of the strips l( are in Contact; with the sides of the tubes. and in order to inerease th(` etlieieney of the heat-Conducting joint between the tubesand the sections K, the edges of the latter are turned at substantially risrht angles. formingr Hanges N of materially greater width than the thickness ot' the metal. and the outer faees t) of Whieh bear against the tubes. The flanges N serve the additional t'unetion of reinforeing and strengthening' tht` seetions K. thereby permittiu;r the tins to be formed of eomparatively thin metal. inet-easing the eooling etiiciency of the fin. Preferably the end P of the sertionsy KY also turned so as to add additional strength to the .strips K.

llaeh oi the .sides (Q ll ot the tubes are preferably provided with a series of cells H pressed outward therefrom and which are arranged in horizontal rows 'l` extending. iu the structure illustrated. trom front to bael; ot' the radiator. the cells of the rows in one side being out of registration with the wells ot the corresponding rows ot the oppwite side. as: shown in Figs. El and 4. the eorrespoiuhng rows upon oppositie sides. however. are in ahnement. These row`1 "l` are spaced `sullieiently to torni channelf` l` between adjaeent rows. of a width to nicely reeeire the ttanges ot the strips K, thereby retaining the latter against vertical movement.

l find it desirable to so bend the flanges N that when the si rips K are engaged with the tubes. the flanges will tend to spread. which will n'iaintain a tight joint between the tubes and the flanges, rthis not only will insure the tubes and the sections K being in heat-condite(ing eontaet at all times. but will also avoid play between these parts, and as the metal ot the tubes and the tins expands when the radiator becomes heated. in use the joints between the tins and the tubes are tightened. Furthermore the connection between the tubes and the tins before described permits a proper joint to be maintained between these members without the use ot solder, materially increasing the heatemiduetirity ot the joint overa soldered one, as will be readily appreciated.

For certain uses I find it desirable to provide the strips K with openings 'l` so as to allow a circulation ot' airvertieally ot' the radiator. as well as laterally. In forming these openings in the strips preferably the metal is merely ruptured so that the area ot the surt'aee ot the strip which is exposed to the air circulating through the radiator is not redueed. Similarly it will be noted that all the metal of the blank from which the tin .T is formed is used. since the turning of the flanges N provides the necessary width to the slots for receiving the tube..

The sides ot the tubes may be spaced in any suitable manner, but spacing is ede@ tively :momplished by forming one or moron-pret'erably a pluralityf-ot' inwardlyextending projections U on the tube sides. as will be best seen upon reference t,o l `igs. S and 4.

ln assembling the radiator the tubes are engaged with the header plates and the edges H I spread. The tins are then engaged with the, tubes. which may be easily and readily accomplished since the channels U form guides which properly position the -strips ot the. tins. Preferably in sealing the joints and eonneeting they parts together, the top and bottoni of the radiator are merely dipped sutliciently to seal the joint between the plates and the edgesI ll I, the front side merely sutlieient to .seal the joints ot the tubes closed by the edges E F and solder the connecting portions L to the tubes, and the back side dipped to attach the tree ends ot the strips K to the tubes. This manner ot dipping not only saves solder, thereby reducing the cost of manufacture and also the weight ot the radiator, but increases the cooling elliciency. since neither the tins nor the tubes are coated with solder. The connecting together of the parts and the sealing ot' the joints, however, may be effected in any suitable Way and it might be found desirable, for certain uses, to dip the entire radiator after the partshave been assembled.

From the foregoing rflescription it will be readily apparent that the radiator is one that may be easily and cheaply manufactured and readily assembled. and that an exceedingly durable structure is provided; also that there are no joints in the tubes interlnediate the sides of the radiator but that they seam of the tube positioned so as to be readily accessible in ease the seam leaks.

wWhile l have shown and described the preferred torni of my invention, I do not desire to limit my protection to the particular construction illustrated, but consider the invention to be ot sutlieiently broad scope to cmbody various modifications. v

'hat I claim as my invention ist-- l. ln a radiator the combination ot' va plurality ot spaced tubes, each ot` a width to extend trom trout to back of the radiator and each having two substantially parallel slightly spaced side walls, the spacing being substantially uniform throughout the width of the side walls` eaeh side wall having a plurality ot cup-shaped cells arranged in ho1i'/:ontal rows extending from' front to baek of the tube., the rows being.spaeed and the correspondingy rows upon the two side walls ot the tubes being opposed whereby guides are formed, and fin strips extending from front to back of the radiator and positioned in the guides formed by adjacent. rows in the cells. the sides ot the strips being in substantial uninterrupted heat-conducting oontaet with the side walls ot the tubes.

Q. ln a radiator the combination with a plurality of spaced tubes, each ot a width to extend trom t'ront to baci( otI the radiator, the forward end of each tube having a rebent portion Closing the seam and forming a reinforced seam to elose the same and the seam haring a plurality of spaced slits, the corresponding slits in the seams of the tubes being alined, ot' a plurality ot fins each having a plurality of strips arranged between ther tubes and ot' a. width to extend from tront to haelt ot the radiator and each En connecting the strips and extending t ansllt) versely of the tubes, said connecting part In testimony whereof I ax my signature being follded to provide a plurality of plies in presence of two witnesses.
