To all if-hom. if. may ooit/:ern:

Be it known that I, FirxnirJu'rimsoii, a citizen of the United Status, and resident of lliilwaukw., in the county oi lvlilwaukee and Stato oi" lVisconsin, have inronted new and usoiul linprovenients in Cooling-Radiators, of which the following is a dosoription,.ref orence being had to the aoemnpanying drawings, which are a part ot this specification.

The invention` relatos to radiators for cooling he circulating water or other finir?, used for reducing the ivniporatnre ot the qvlindurs of an inirrnal roinhnstion isi' gine, and is more partiifularlj.' tlvsinnml for nso on automobiles.

At present tno ronnnon praifthfv in railiator Construction is to foi-1n the water and air passages b v using soldered or otherwise rigidly sornrod toM gethor and to the, radiator tank to form a yt;onsidrrablr-J- difficulty with radiatorsoi this kind arises when, through Some Cause, a leak occurs, for in suoli a Caso it becomes necessary to partially or wholly dismantle tho radiator to repair the loak. it is tho'ossontial. ohji-ot ot the prisent, invantion to obviate this liflieulty by providing a. radiator whirh is mailiup ofa plurality oi Separate iiukipendont radiator units which can be easily assembled together to t'orin the radiator and in which any one ot thev units may-be readily rrniovod and roplaead if a. leak occurs, or if a new unit is not available tho remaining' units niav he assembled to constitute-the radiator.

A `further object. ot thin invention is to irovide a radiator which may he standardized, that is, by making the radaor of inde1 pendent radiator units of different, sizes, these units. may be keptfin stock by the d'otih ers and make it easy to f a' oar owner to reA oral features hereinafter n `portionlariy defined by claims at the oonm pair his radiator., if a leak occurs, by par chasing a new unit which, because of the simplicity of construction of the device, he

may put in the radiator hin'iself' in the place of the defective unit.

, The invention is further. designed to pro vide a radiator oom osed of a plin-zi'litji-v of i dependent uniti-3 w 'eli are readily removable ai'niili'eplaoeable so that. little time'is taken npl in repairing the radiator..

The invention further consists in the sevsietforth .and more cinssion. hereof.

,in general, the device comprises a supporting' traino, oppor and lower tanks so- :foreii to the traino. and a plurality of indo pendent removable radiator units coinmunb rating-r with thc upper tank and the lower tank Thil upper tank forms thesupply tank for the radiator units and the lower tank constitutes the outlet from said units and connections are also providedfor Coniiooting up the radiator to thociroulating system for coolingthe engine..

Thr frame vonsists of upright supporting ineinhirs or platos f3 which may be Secured to any suitahlr support. as the Side frame members' ot an autoniohile and ineans for eonnorting Vtho-suppl,"and outlet tanks to said nwinhers. This moans comprises an uppir plate 7 which is scoured at its Sides R to the 'upper portion oi thoI mumbai-seti in any suituhlol manner. as h v rivets 9, and whit-h is 4provided with a hack portion 10 haring a pipe connection 1l formed therein for wearing ono ot the pipes in the circulating; System (not shown) thereto, and a lowor platt', 12 which is secured at its sides ifi to tho lower portion of the members 6 in any suitable manner, as` by rivets .14, and

which provided with a back portion 15 having' pipe connections 1G formed therein for oonnecting up some of the pipes in the circulating system .(not shown) thereto.

Tho upper or supply tank or reservoir 17, secu-red to the upper plato 7 by bolts 18 4wl'iich pass through apertures 19 in the sides of the tank and through sleovos 20 Within tho tank, secured thereto by soldering or otherwise to make the tank water tight, and whifh bolts also pass through v'zi/rubber gasket 2i secured at the hack side of the tank and throl'igljl apertures Q2 in the back portion 10, said bolts being secured to the baul-z of the plate 7 byinnts 23. The .gasket 21 is provided. with .an aperture 24 in wmlif 10olv inunication with the pip.; 11 and the tank '1T with an inlet 2V communicating with the pipe. 11, through the. aperture 24. The tank 17 :is prorided with a filler opening 17 and with a plurality of feeding channels 26 formed by depending side portions 27 ot' the bottom of the tank, and a transrerselyextending notched. filler plate 28 secured thereto to ,torni a water tight compartment. These. channels hare oppositely disposed outlets 2).

The. lower outlet or collecting tank or conduit 30 is secured to the lower plate 12A by bolts 3l which' pass through apertures 32 in the sides ot this. tank and through sleeves Sltwithin the. tank. secure-d thereto by soldering or ottu-rwise to make the tank water-tight, :unl which boltsl also pass through a rubber gasket ill secured at the back side oi the tank and through apertures 35 in the back portion 15` said bolts being secured to the back ot' the plate 12 by nuts 3G. The. gasket 2H is provided with apertures it? adjacent the pipe connections 1G and the tank Il() is provided with apertures 3S in communication with the pipes '1G through said apertures 3T, The tank provided with a pluralit.. \v ot' inlet channels 39 formed b V upwardly projecting portions 40 of the top ot' the tank and a notched filler plate 41 similar to the plat-e 2S secured thereto to form a water-tight compartment', said channels beingpretcral'ily disposed in the central portion ot' the top ot the. tank. These inlet channels 239 hare a pluralit \v of oppositely disi'iosed inlets 'lhe tank 30 also has compartments ltformed in onev ot the sides thereof and a suitable torni of heater, such as an acet \'lene gas burner 44 ma.)7 be disposed in each o1" said compartments to heat the liquid in the tank during times otl cold weather when there. is liability ot the cooling` liquid freezing. Each ot these burners 44 is eonneetiul to a. suitablel source of tuel supl'ily, not shown.

The circulating means between the upper and lower tanks comprises a. plurality of indepeiident removable radiator units 45. -Each unit. 45 consists ot a hollow member formed of oneI or more plates 46 to form a channel 47. For the purpose of circulating air through the units, their sides are punched in numerous places to form air channels 4S. These channels tti are torn'n-*din verticallv extending rows, the. channels in adjacentrows being arranged in staggered relation. While the holes or small air channels 4S thus formed may-be, of any desired shape, I pre for to form them, as shown in Fig. 5, in which there, is a. central orifice. 49, a section ot {.lgraduall)7 decreasing capacity in the direction of air flow 50, and a. section ot 'gradually increasing capacit)r in the direction 'of flow 51. Such channels in etlecty form small Venturi tubes and as is well `provide. a flange 52 on one side 'which is crimped down adjacent. the aperture made 1n the other slde, as shown 1n F1". 5. The

top and bottom of each radiator unit is proi vided with filler pieces 53 and 5t, respectively, preferably of metal secured within the hollow of the plate or plates '.tG by solderinff. The top filler piece and the sides of the plates are. provided with n notch or channel 55 and the lower tiller piece and the sides ot the' plates with a notch or channel 56 which channel, through means hereinatn ter described. communicates with the upper and lower feed channels 2G andBQ. respectirelr. Thus the tiller pieces provide solid ends tor each ot' the units and the channels therein communicate with the hollow 47 of the unit.

From the foregoing' description it will be noted. that the channel -IT :t'ormed by the plate or plates 4,6 and provided with the upper and lower ller pieces and the air channels extending through the broad sides thereof form an independent radiatorI unit'. and means are provided tor detachably securing each of thesel units in position within 'the radiator and in communication with the upper and lower tanks thereot'. It' will be further noted that, as the. channels 55- and 56 extend inwardly, either end of the unit ma.;7 be used as the top or bottom.

This means comprises a plurality of bolts 57 which pass through apertures 58 in ,the sides of the units and the upper and lower filler pieces 53 and 54 and through apertures' in the sides of the reservoir and outlet cenduit and the upper and lower litter plates Q8 and 41, the units being strung on these bolts and disposed between the' upper and. lower tank, as shown `in Fig., 2, and being spaced from each other by apertured wash-` ers 59, the. plates being tightly held against extending portions of the reservoir and tank air channels in the units themselves, I form an air space between each ofthe rows of units and between each of the units in a row and thus Provide for an efficient circulation of air to cool the'wat'er or liquid passing through the radiator.

'lheI units are assembled, as shown in Fig.

,the washers and 'also against the inwardlyv 2, awasller 59 being interposed between adjacent unitslat the topvand bottom thereof and the apertures of the washer are alined with the channels 55 and 56 in the filler spaces and with the openings 29 and l2 ofV the feed channels for the upper and lower As the cooling liquid flows along throughthese channels it also flows downwardly `through the channels 47 inf the units and is subjected to the action of the currents of cooling air and thence flows along' through the channels formed by the washers 59' and the .notches or channels in the lower end of the units, thence through thc inlets 42, into thebhanncls B5) and the outlet tank 30. The upper and lower tanks are suitably connected in the liquid cooling system connected with the cylinders of the engine.

It tor any cause one rof the radiator units should lea lr, it can be readily ascertained in which row of units the leakoccurs, and the units in this row may be removed by removv ing the bolts 57 and the leaky unit may then be :readily replaced with a new one or the leaky unit, it it be an intermediate one, may be rrnnoved entirely and the remaining units and accompar fing washers .may be moved up and the radiator will again. he ready to perform its 'tmlotions as the removal of an hitter-mediate unit only shortens upy the row. In case the :front or back units should leak and no new units were availablekto be sub stituted therefor, the outer leaky unit may be dispensed with and the intermediate' unit adjacent the outer unit inay be utilized by plugging up the front of the upper and lower channels in the unit.

I am aware that the invention above described is capable of considerable variation and modiication and I therefore Wish it understood that any construction which would come within the scope of the appended claims is within the scope of my invention. y l

"What I claim as Iny invention is member provided with filled ends having channelsy extending therethrough into the hollow of said member, and Vhaving a plurality of air-channels extending therethrough, each of said air-channels being of gradually decreasirgcapacity followed by 1,. As an article of manufacture, an inde- A 'pendent 'radiator unit consisting of a hollow gradually increasing capacity in the direcf tion of How of the air therethrough.
