RADIATOR;

' Application filed October 22, 192.4. 7 Serial Nev 15,112.

My invention relatesto improvements in radiators-for automobiles. I An object of the invention; is to provide an .improvedradiator forwater cooling systems for internal combustion. engines of automobiles, said. radiators being formed with anegress' conduitincorporated in the radiator structure,. the intake to said conduit-being arranged to provide for maximum efficiency in. the; use of theradiator, and the outlet being arranged to provide for'easy access to the radiator for the purpose of dispurpose of repairing the radiator. p

W'th the foregoing and other objects in view, which will appear in the following description, the invention resides in the-novel combination and arrangement of'parts and in; the details of construction hereinafter described and claimed.- 2

In the drawings Fig; 1 is an elevational View illustrating the back of a radiator embodying my invention, a portion of the raw diator'bei-ngr brokenaway to disclose parts,

' otherwise concealed, and Fig. 2 is avertical sectional view taken: on, the I. I p Referring tothe drawing. it will be seen that my improvement includes aicore Ai top tank 10,- bottom, tank 11 and shell 12. A The are secured in the bottom of the tank 10 and open therethrough into said tank, while thelower ends of said tubes are secured in the top :of the tank 11 and open through said-top into saidv tank 11.- The unitary structure thus afforded by said core A and tanks 10, .11 is framed by the shell or case 12. The upper tank 10 is equipped with the usual. filler-.rieck l5, cap 16 for said neck,

line 2-2" of V ingress hose connection 17 and vent tube '18.

I The ordinary automobile radiator has an egress hose connection medially of the ends of the lower tank and at thebaok or bottom thereoi. In such position this hose oonneoe tion is exceedingly diiiicult to reach and it locates the hose-nipple attached thereto in a I place wherein the accumulation of deterior ating oil and grease on; the hose isgreatest. This'rcondition existing the lower hose-nipples require frequent replacement with the attendant expenditure of much time and labor, which expenditure oftime and labor also required in the simple step necessary preparatory to the removal; of the radiator for repair or to permit of access to parts of the automobile'adiacent thereto, 1, there M orries.

fore omit the usual lower hose connection, 1

and inits steads'upply an egress Conduit 19' within the bottomot the tank 11, a pipe-[20.

rising from. said conduit through the core A and ahose COIlI'Z'GCii-TOI} 21-issuing rearward from the upperend of said pipe 20st one side-margin of the radiator. Thus. located, saidhose connection 21 is readily accessible" and in most instances holds-the rear hosenipple in position comparatively 'free from theaccumulation of oil and grease, In arr'anging the conduit 19 and pipe 20: to locate thehose connection 21; as: above explained,

I have provided for maximum temperature IGClliClllQ capacity of the radiator. Thecon- 'duit 19, preferably an integral part of the lower tank 11; opens at the bottom of said tank midway between the ends thereof; said conduit being extended toone end of the tanln thence turned upward to the top there of. Fitted at itslower end in the upper end of said conduit 19 the pipe 20 rises through the this 141-.- These lins fit snugly around the pipe 20., thehose connection 21 on saidpipe being turned rearwardly in thee-ore A and reaching back therefrom at a point approximately midway between the top "and bottom of the core and in the margin at the side thereof. Thus it will be understood that the conduit 19 drains the tank llfrom. a central point therein; that the core fins l tserve as cooling elements for the pipe 20 .and'pi'pe connection 21, and that said connection is disposed so as to be ea 'ly accessible and to locate the complementar hose nipple in position .iree train aceun'lulations of oil and grease. t lorering an opening termed in the bottom oi the tank ll directlr beneath.

the inner extremity ot' the conduit 19 is a cover plate 23. This cover plate may he removed by unscrewing the attaching screws ill to permit ot' the insertion oi an instrument through the opening 29 and into the conduit 15] for cleaning said conduit. Said cover plate 2; may also be removed to perlnit of the draining otthe radiator when a lzn'ger drain than that attorded by the conrentional drain-mark S35 is desired.

The radiator applied to an automobile chassis in the usual manner, stud blocks 26 being provided on the underside of the tank 11 for a ttaclinnent to the chassis frame. The hose XOlllltt't'lfill l'iis mninected as usual through a eim'rentitnml hose-nipple with the. feed side oi" the water pump of the engine, and the hose ('(Hllitt'tlUll St is likewise connected with the return side of" said pump.

Changes in the spceitic torin of in) invention. as herein disclosed, may be made within the scope of what is claimed without depart ing from the spirit elf in invention.

lilaring described my invention, what I claim as new and desire to protect by Letters Patent is:

1. In a radiator, a core including ducts for the passage ot water theretln'ongh and tins associated with said ducts for cooling the same, a tank 2 t the top oi the core teeding into said duets, a tank at the bottom of the core into which said ducts empty, an egress conduit embodied in the lower tank structure, said conduit opening midway between the ends of said tank at the bottom thereof and extending alongsaid bottom to one end of the tank and within the same and thence u iiward to the top ot the tank, and a pipe rising through the core from said conduit to a pointsubstantially medially ot the top and bottom at saidcrne, said pipe having a fitting turned rearwardly through the core and accessible at the back thereof, the fins ot the core providing cooling ele ments for said pipe and fitting.

2. In a radiator, a core including ducts or the passage (It: water therethrough and tins associated with said duets 't'or cooling the same, a tank at the top of the core feeding into said duets, a tank at the bottom of the core into which said ducts empty, an egress conduit within the lower tank structure, said conduit opening between the ends of said tank and extending loinz'itudina ly thereof to one at its ends, and a pipe rising); from said conduit through the core to a point between the top and bottom thereot, said pipe having a fitting turned rearwardly through. the core and accessible at the back thereof, the tins ot? the core pro viding cooling elements tor said pipe and fitting.

3. In a radiator, a core including ducts tor the ntestine o'l water theretlnrough and tins associated with said duets :for cooling the same, a tank at the top ot the core feeding into said ducts-i, a tank at thebottoni ojt' the core into which said duets empty, and an egress pipe rising through the core from the lower tank to a point between the top and bottom of said core, said pipe having a fitting turned :rearwardly through the core and accessible at the back thereof, the tins of the core providing cooling elements tor said pipe and fitting.

8. In a radiator structure including a core, an upper tank at the top of the core foed- I ties and a shell encasing the upright edges ofdthe core, an egress pipe connected with and issuing upwardly from the lower tank between the planes of the front and rear faces of said core and having an outletfita ting at its upper end accessible at the rear 7 ofthe core between said upper and lower tanks said egress pipe being rigidly braced 10 by the structure remotely from the lower tank.
