. COOLING RADIATOR.

Application filed December 17, 1923. Serial No. 881,159.

To all whom it may cor-cm:

Be it known that I, VViLLIAM A. ODEN- DAHL, a citizen of the United States of America, and resident of the city and county of Denver, Colorado, have invented a new and useful Cooling Radiator, of which the following is a specification.

' An object of this invention is to provlde an improved construction for cooling radiators adapted for useon automobiles for the purpose of cooling liquid employed to prevent overheating of a gasoline motor .used to drive the same.

A further object of this invention is to provide improved .means for facilitating assembling, dismounting, separation and repair of the parts of a cooling radiator.

A further object of this invention is to provide an improved construction. for several of the parts of a cooling radiator;

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out v in the claims and illustrated by the accompanying drawing, in which- Figure 1 is a front elevation and Flgure 2 a side elevation of a radiator embodying my improvements, the shell being omitted. Figure 3 is ahorizontal section, on an enlarged scale, on the indicated line 3-3 of Figure 1. Figure 4 is a detail perspective illustrating one form of construction and arran ement of end bars, fins and struts employed in the device. Figure 5 is a vertical section through a part ofthe radiator core further illustrating-the structure shown in ,Figure 4.

- Figure 6 is a'detail perspective showing a modified construction for. the fins, whereby. .a part of each fin constitutes a strut or sup-. port for a superposed fin.

Figures? and 8 are vertical sections and plan respectively illustrating various forms of connecting radiator tubes to a tank 'In theconstruction of the radiator as shown the-numeral 10 designates a bottomtank, 11 an upper tank, 12 each of a series of vertical tubes connecting, communicating with and spacing apart the tanks 10 and 11,

'13 an outlet pipe for the bottom tank andlt an inlet pipe for the upper tank; said upper tank also being prov-idedwlth a filling nipple 15 at the center of its top. In a general way the tanks and tubes are constructed in a common and well known manner and are Y holes.

not involved in this invention except as a foundation for the other elements and as hereinafter described. In Figures 7 and 8 a tank header 16 is shown formed with holes therethrough adapted to receive one end each of tubes 12. The holes in the header are reamed out and tapped at one end and glands 18, 19, 20, or various forms, are mounted loosely on the several tubes and are adapted to be screwed into the tapped portions of the holes in the header and, at their inner ends engage gaskets 21 and seal the joints between the tubes and header. The gland 18 is formed with a tapered inner end opposed to atapered bottom of the reamed out portion of the appertaining hole and the gasket 21 therein is located between saidtapered end and bottom. The gland 18 also is otherwise cylindrical and is formed with notches 22 in its outer end adapted to be engaged by a spanner for operation of the gland, either for seating or unseating thereof. ,The tapered end of the gland l8 and tapered bottom opposed thereto are sphere-shaped.

The gland 19 is formed with a .frustum shaped inner end opposed to a frustum shaped bottom of the reamed out portion of the appertaining hole in the header and the gasket 21 therein is located between said end and. bottom. The gland 19 also is formed with a nut 23 on its outer end adapted to'be engaged by a wrench for op- I eration of the gland, either for seating or unseating thereof. The gland 20 is formed with a fiat inner end opposed to a flat bottom ofthe reamed out portion of the appertaining hole in the header and the gasket 21 therein is located between said end and bottom. The gland 20 also is formed with a nut .23 on its outer end adapted to be engaged by a wrench for operation of the gland, either for seating or unseating thereof. The header 16 may constitute the top of the tank 10 or the bottom of the tank 11, and is of material and considerable thickness to accommodate the reamed and tapped The gaskets 21, under compression of the glands, provide and maintaln frictional engagement with the tubes. 12 sufiicient to keep said tubes in proper relation with the tanks, thus providing means for conveniently assembling, or removing any tube for repair or substitution.

The 'core of the radiator is built up and filled in of two sets or series of fins 24, 25,

all of which fins are alike in form and construction and are interchangeably usable. Each set or series of fins24, 25 is connected with and carried by end bars 26, 27 and 28, 29, two for each set or series, and said end bars are of like form and construction, except as to fastening means, and are-substantially interchangeably usable. The end bars are adapted to be mounted in pairs between end portions of the tanks 10, 11 as shown. -The fins 24, 25, are each formed of thin sheet metal with a fold or roll 30, on its outermost long margin and is formed with outwardly-opening notches 31, extending thru the fold or roll and of a width corre sponding to the thickness of and adapted to receive the end bars 26, 27, 28, 29 respectively. The notches 31 extend throughout somewhat more than half the width of each fin. The end bars 26, 27, 28 and 29 are formed with inwardly-opening notches 32, one for each fin of the respective series, and said notches extend throughout substantially half the width of the bars and are adapted to receive those portionsoi the fins at the inner ends of the notches 31. Thus the fins Y and end bars are halved together for assembling in sets and they may be connected by culation of air between the tubes and between and through the fins adjacent to the tubes when the fins are assembled as shown in Figure 3. These notches 34, 35 also permit the sets of fins to be withdrawn from the tubes by lateral manual movement of theend bars. Struts, spacers or supports 36, 37 are formed of thin sheet metal with folds or rolls 38 on their inner margins and said struts are formed with outwardly- opening notches 39, 40 adapted to receive portions ofthe fins24, 25, said fins, in turn, being formed with inwardly- opei'iing notches 41, 42 adapted to receive those portions of the struts at the inner ends of the notches 39, 40. The struts are arranged vertically between transverse rows of the tubes 12 and frictionally engage the fins, or they may be secured to the fins by drops ofsolder 43, so that saids'truts may be removed and replaced with the sets or series of fins in lateral manual movement of the end bars. Apertured ears 44, 45 are fixed to the outer surface of inner marginal portions of the end bars 26, 27, 28 and 29, in sets near the upper and lower ends of said bars, and when the parts are assembled as shown said ears register vertically on opposite sides of the radiator and are connected in sets by pins 46 adapted for manual removal and replacement. The interengaging pins and cars provide convenient means of connecting the end bars in pairs on opposite sides of the radiator and through said end bars, for connecting the sets of fins and struts on opposite sides of the median line of the radiator.

li'pon removing all the pins 46, theend bars, tins and struts may be removed forwardly and rearwardly from the tubes 12, which done accessis had to any tube for the repair, removal or replacement thereof, Or, under the same conditions, any strut or fin may be removed or repaired.

After any repair or renewal is made the sets of series of end bars, fins and stints may be replaced relative to the tubes 12 and reconnected by the pins 46 in intimate and stable relation to the tubes. \Vhen assembled as shown, the struts support the interior portions of the fins in proper spaced relation, and said struts and fins divide the air, forced by tan not shown, in passing througii the radiator and about the tubes, also permitting the air to circulate freely up and down and around the tubes, thus applying the cooling air intimately and freely to the tubes. In Figure 5 both the fins 24, and struts 36, 37 are shown contacting on the median line of the radiator.

In Figure 6, the struts as separate entities are omitted, and the fins 24, 25 are formed with recurved-integral lugs 36, 37' extending upwardly therefrom in the locations otherwise occupied by the struts. The lugs on each fin engage and support the fin above it, and said lugs have substantially the same function as the struts in supporting, spacing and bracing the'fins and in operating with said fins to divide the air passing through the radiator.
