ANTIJEREEZING DEVICE FOR RADIATORS.

Application filed November 24, 1920. Serial No. 426,205.

To all whom it may concern:

Be it known that I, THEODORE A. MILU- rm, citizen of the United States, residing; at Deal-born, county of \Vayne, State of Michigan, have invented a certain new and useful Improvement in Antitreezing Devices for Radiators, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same. reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to a device designed to insure the water circulating through the cooling system. of an internal combustion engine against freezing during cold weather when the engine is not in operation.

The object of the invention is to provide means whereby the water may be drained from the cooling system and delivered to an anti-freezing container designed to maintain the water at a sufficiently high temperature that it may not freeze and to return the warm water to the circulating system of the engine that its heat may aid the ignition of the gas delivered to the combustion chamber of the latter.

ln putting this invention into effect a pump is employed adapted to drain the water from the water cooling circulating system of the engine upon parking the m.otor vehicle for any considerable period or upon housing the car over night, the water being delivered thereby into a heat retaining container of the so called thermos type, from which the warm water is afterwards withdrawn and returned to the water circulating system of the engine when it is again desired to drive the vehicle ;the pump being operated either manually or through power derived from the usual starter employed to crank the engine.

A further object of the invention is to provide means whereby the operation of the pump and the delivery of water to and from the water circulating system. may be controlled from the drivers seat.

With the foregoing and other objects in view which will appear as the description proceeds, the invention further resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes may be made in the precise embodiment of the invention herein disclosed without departing from the spirit'of the same.

In the drawings accompanying this specificat1on:

Figure 1 is a vertical longitudinal sectional view through a'fragmentary portion of a motor driven vehicle showing the in vention connected with the water circulating system of a prime mover.

Figure 2 1s a view partly in section and partly in elevation showing the pump, and

pipes leading therefrom to a plural valve casing, 1n turn connected with the radiator of an internal combustion engine,' as installed upon motor vehicles,the valves housed in the casing being adapted to control the passage of water to and from the radiator and to and from a heat retaining water container,-the view shows the position occupied by the valves when the water is passlng from the heat retaining water container back to the radiator.

Figure 3 is a sectional view through the plural valve chamber showing the valves housed therein in the position they occupy when water is being withdrawn from the radiator and the water jacket of the engine, for the delivery to the heat retaining water container.

Figure 4 is a side elevation of the plural valve chamber, showing means for simultaneously operating the several valves.

Figure 5 is a horizontal cross-sectional view through the plural valve chamber.
