AHTIFBEEZING DEVIGE FOB AUTOMOBILES.

Application filed May 13,

To all whom it may concern:

Be it known that I, Fnno Wmmmno a citizen of Germany, and a. resident of Iddmonton Alberta Canada, have made certain new and useful improvements in Antifreezin Devices for Automobiles, of which the following is a specification.

My present invention relates generally to automobiles and other motor cars, using water cooled motors and particularly to anti-freezing devices in connection with the radiators of such motors, and has for its object the prevention of loss by volatilization of the volatile ortions of anti-freezing solutions common y used at present.

As well known a. common anti-freezing solution for radiators is formed by adding alcohol and glycerin to the water supply in a certain percento e which at present can only be maintained at an eflicient point by almost constant addition of the more volatile alcohol. This is due, as is well understood, to the exhaust of the alcohol fumes through the overflow pipe, and m invention proposes the employment of simp e, efiective means for conden these fumes and returning the liquid 0 condensation into the cooling system.

I reierably accomplish the desired result hy an apparatus ea able of ready attachment to an automobi e without interference with the normal opleration thereof, of the nature and extent w ich I will now describe with reference to the aecompian g drawing forming a part of this speci ca ion, and wherein Figure 1 is a top plan view of the chassis of an automobile showing the practical application of my invention;

Fig. 2 is a side elevation thereof, and

Fig. 3 is a vertical section through the condensation tank.

Referring now to Figs. 1 and 2 I have shown an automobile chassis 9 including a motor 10 of a water-cooled type, the upper portion of the jacket of which communicates b pipes 11 with the upper portion of the ra 'ator 12 the lower portion of which communicates hy pipes 13 with the water pump 14, in turn connected by a pipe 16 with the lower portion of the radiator 12..

The overflow pipe 16 of the radiator is, in accordance with my improvements connected to one end of a ipe 17, which extends rearwardly to a con ensercoil 18, the outlet of which leads to the upper portion of a.

tank 19. The condenser coil 18 and tank 19 are suitably mounted beneath the rear portion of the chamis 9 sufiieiently remote, at least, from the motor 10 to be well beyond the influence of its heat, so that the alcohol fumes will be condensed to liquid form and discharged into the tank 19 instead of being exhausted into the atmosphere as usual.

The tank 19 has an outlet fitting 20 at its base containing an outwardly opening spring seated valve 21 a pipe 22 leadin from this fitting 20 to the intake pipe 15 o the water ump 14. Thus accumulated, pressure wit 1 tank 19 periodically forces the valve 21 from its seat and permits the condensod liquid to pass into the cooling system again throu h t e pump where it is tho'rou hly mixe with tie radiator solution.

11 this way, by providing against air or fluid leaks I am able to maintain the solution at its highest efficiency at all times, and avoid the necessity of constantly replenishing the alcohol as is necessary at present, and it is to be observed that accomplish these advantages by an apparatus which is at once simple, inexpensive and durable in use.

I elaim:--

1. The combination with a water cooling radiator for motors, having an overflow pipe of a condenser coil connected to said outer end of the overflow pipe, and a liquid trap connected to said condenser coil for receiving fluid therefrom and having a pressure controlled outlet.

2. The combination with the cooling system of a combustion motor including a radietor having an overflow pi e, of a. condenser separate from the radiator and remote from the motor and, connected at one end to said overflow ipe, and pipe connections between the oliher end of said condenser and said oooli system for automatically and periodica y returning liquid from said condenser into the cooling system, as described.

8. The combination with'the cooling systom of a combustion motor, including a redial-or having an overflow pipe, of a pipe leading from said overflow pipe to a point out of the influence of the heat of said motor, a liquid trap with which said latter pipe communicates, and a valved connection between said liquid tra and a portion of said cooling system, as ascribed.

4. The combination with the cooling system of a combustion motor, including it radiator having an overflow pipe, of pipe leading from said overflow pipe, a condenser with which said latter pipe communicates, a liquid trap into which the condenser discharges having a valved outlet and a pipe connecting said valved outlet with {t portion of the coolin system.

5. The com )inzttion with the cooling system of a combustion motor, including a redintoihaving an overflow pipe, of a pipe leadlng from said overflow pipe, a condenser with which said latter pipe coniuiunn-ates,

liquid trap in the form of it tnnk into the upper portion of which said Culllltillfifil' discharges having an outlet at its base. at pipe connecting said outlet with it portion of the cooling system, and an outwardly opening spring controlled valve controlling said outlet.
