' RADIATOR.

To all co'hom itmay concern:

Be itllrnown that I, WILLIAM A. .FINLAlY- :SQN, .a a citizen of the United States ofAmer- [libel-invention relates .to radiators designed to lower the temperature of the-cooling water for'anengine by means of air, and

is particularly applicable to-autornobile ra' .diato rs. Oneobject of the invention isto provlde ,a snnple construction comprising tubessadapted for the passage of air and water arranged adjacent to-each, other for ga-substantial id-istanoe. .Another object is the provision of-a chamber in the radiator for receiving the air :after passing through thewater space. The invention has for further objects the :novel arrangements and combinations of parts as more fully herein: after set forth.

"9 is the lower or: base portion of the radiator c'asing which is suitably secured to the radiator casing which is suitably secured to the cham- 'ber3' and forms therewith, the lower air chamber 10. 11 is a series of vertical'tubesconnecting the upper and lower air chambers -zthcse tubes extending through the wa-ter tubes 4 and in parallelism-therewith. Thefront of the lower air chamber 10 is open andthe. bottom wall 12 of this air l Specification of Letters- Iaten Iing forward; 1

The by-;pass shownin Fig.

This .heaterg-may be secured to the radiator as bybeing engaged with the hook 18 upon thelower front side of the radiator.

and S are secured to each other as by means I ofrthe rods-19 which engage laterally extending. flanges upon the chambers .The

bottom and" top, orthe headers, of-the respective 'airchainbers 2 and '3 are provided with the bosses 20 which have-the conical seat portions .21 for? engaging the conical ends 22 of the tubes 4. By securing-theseheaders to each other it will be-seenthat the tubes .4? will be firmly -secured in place-and thatthe joints -at. the ends of these tubes will be water-tight] The air tubes 11 are also preferably secured tothe core 1-, and as outer headers, o f the' chambers 2 and 3 reshown inf-the upper and loweresides, "or the' 'spectivelyr are provided with cup-shaped bosses23, the bases of which are apertured for the :passaigeof the. ends of the tubes '11 therethrough: 2-1 are conical bearing portions upon the basesof these bosses which are engaged bv-the :conical ends 25 of'the bush ings 26 threadedly engaging in the cup- .shapedibosses. the arrangement being such that upon'inwa-rd movement of the bushings their inner conicalends are laterally forced into firmengagement with th ends of the tubes. These bushings are preferably formed with-hexagonal heads 27 for engagement by a wrench. j v

28 are suitable heat radiating finsextending across and around the tubes 4.

From the above description it will be read-; ily seen that I have provided a simple radiator construction which can be readily manufactured and furthermore in which the air passing to the upper chamberis in contact with the water space of the radiator for a substantial distance so as to absorban appreciable amount. of heat. Also this heated air canbe utilized if desired to heat the interior ofian automobile body or sedan. I As shown in Figure-4, the front'of the airreceiving chamber29 is closed and its bottom is open and the lower heatr'adiating fin3 0 extending transversely of the seriesof tubes has a rearward extension 3lwhich is curved downwardly and forwardly beneath the air receivingchamber 29 and terminates at its front wall. This arrangement is such that-a portion of the cooling air in passing through the radiator and around the tubes,

is directed into the air receiving chamber by the extension of the .air cooling fin upon movement of-the motor vehicle car ing the radiator. Another'feature as disc osed in this, figure, is the device for filling the radi ator water chambers and water tubes with water. "This member 31 has the portion'32 which is adapted to extend into the filler neck 3301f the radiator. The portion 32 for thewatercurves downwardly and rearwardly to lie adjacent to the rear face of .the upper water chamber 34, this rear face having an aperture therethrough communicating with the'passageway The device also has the rearwardly and downwardly extending tubular portion 35 which is adapted to be connected to the water jacket of the engine and by means'of which the hot water from the engine is conducted into the upper water'chamber 34$.

9. In a radiator the combination with an upper air chamber and upper water chamber th'erebeneath,'-of means; for directing water into said water chamber, comprising a passageway'leadingfrom the filler neck of the radiator, downwardly and rear-wardlyto lie adjacent to the rear face of saidwater chamber, said 'fpassa'gewa'y communicating with said water chamber, and a second passagewa'y adapted to conduct water from an engine] water jacket, said second passageway communicating with said 10. Ina radiator, the combination with hollow upper and lower water chambers, of tubes connecting said chambers and having their ends abutting the inner walls'thereof, means for clamping saidinner walls 'upon water chamber Y the ends of said tubes, cup shaped bosses upon the outer walls of said water cham bers having apertured bases and conical bearing portions adjacent thereto, tubes ex tending through said first-mentioned tubes and into said cup shaped bosses, and bush ings threadedly engaging in said cup shaped bosses and having conical ends cooperating with the conical bearing portionsupon said cup shaped bosses for firmly engagingsaid tubes. v v

11. In a radiator, the combination with hollow upper and lower water chambers,
