I SCHINDLER' AssIeNoR 'ro SAID BRADLEY AUTOMOBILE RADIATOR CONDENSER Application filed January 23, 1931. Serial No. 510,736.

Our invention has referenceto an automobile radiator condenser, and has for 1ts chiet purpose to .prevent a high temperaturein the ing point while they are being operated. By

the use of the present invention steam or other vapor formed in the radiator is condensed and returned thereto in a cooled condition, and the temperature of the liquid contents of the radiator kept at or near an established point. As a result there is little or no evaporation, and the same filling of alcohol will be sufficient for the entire season, or longer.

Another purpose of the invention is to provide means for preventing a sudden discharge of water or steam through the device.

The above named, and other features and advantages of the invention will more fully appear from the following specification, reference being had to the drawings accompany ing the same, in which F ig. 1 shows the invention as it appears when in use.

Fig. 2 is a longitudinal section of the post 5 and related parts.

Fig. 3 is a. similar view of a modified form of the device.

In Fig. 1 is indicated in broken lines the upper part of a radiator A, provided with a cap B, in which is supported a post 5, by means of a hollow stem 6 having a threaded connection with said cap. The upper end 7 of the passage in the stem is of reduced diameter and in the lower part of the passage there is fixed a pin 8 upon which rests a ball 9. Inserted in one side of the post 5 and opening into the recess 7 is a nipple 10, fitted with a coupling 11, in which is held the lower end 12 of a helical coil 13, the upper end 14 of which is connected-with a pas-. sage 15 in the upper end of the post 5. A,

connection 16' is fixed in the upper endof said post, forming a continuation of the passage 15, and fitted with acoupling 17, with which'is connected the upper end of an over-:

flow pipe 18, which normally extendsdownwardly in front of the radiator.' said pipe has a pivotal connection, so that i-t'ca nbe swung upwardly into a horizontal position. and rotated with the coil and 'radiator'cap. or return; the

when it is desired to remove same.

radiator the vapor arising from the contents of the radiator will find its wayinto the lowerfend of the coil-13, where it will be condensed by the cool air aroundthe coils, and

the condensate returned to the radiator.

In practice, the vapor or steam will rarely rise more than half the height of the coil, but sufiicient piping. is provided to take care of any normal evaporation. r i

In the event of a sudden splurge of water" .or steam upwardly the. ball 9 will be carried. upwardly thereby and seated against theshoulder at the lower end of the recess 7,

shutting off further movement of the water upwardly. The lower end of the connection 6 can also be provided with a cap 19, having an intake opening in its sides, which will interfere with any direct movement of the water. upwardly into the lower end of the post. The post 5 not only forms apart of the condensing apparatus, but it provides a very substantial support for the coil.

In Fig. 3 is shown a form of the invention in which the post 5 is replaced by a cylindrical portion 20, in the upper end of whichis tapped a plug 21, having an opening 22 communicating downwardly with a chamber 23, from which a passage 24 extends downwardly into a threaded stem 25, for connection with a radiator. In the lower end of said passage is a pin 26 and ball 27, for operation similarly to theball 9. In the chamber 23 is a float 28, connected with a stem 29, on which is a valve 30, normally closing the passage 24.

The lower end 12 of the coil is connected at the lower end of the cylinder 20, and the up- VVhen the invention is inposition on a per end 14 thereof is connected with a nipple I 31Vfix'ed in the plug 21. Fixed to the upper V endof the nipple 31'is a 'cap 32, having an 7 opening 7 V diameter which will permitthe escapeof alr 33 beneath which is a ball 34, of a through said opening when vapor enters the lower end of the coil, or the return of air "therethrough in case the amount of vapor in r the coil becomes less.

Its action is that of a breather. Inthe event of a sudden move-' ment of water or steam upwardlvthr'ough the cylinder 20, however, the'ball 34 will be raised, closing the opening 33, andpreventing the escape of such water or steam. In ,t

case there should bean excessive amount of condensation, so that it would pass upward-1 ly through the coil,'a s is likely to' happen with 7 large trucks or other vehicles havingengines or-' large capacity, such condensationvwould ass out of thetop of the coil and downwardly into the chamber 23, and upon 'a sufficient amount collecting therein the float 28 will be raisedith'ereby, elevating the valve 30, and permittingvthe products of condensation to flow downwardly, and back into the radiator;- The weight and valve are of sufficient weight: to prevent the movement of vapor upwardly into the chamber 23.
