��THE problems of keeping the engine of an automobile warm during freezing weather so as to prevent cylinders from cracking, to make starting easy and to heat the body interior for comfort are solved by the combination engine and body heater shown in the accompanying illustrations.

The apparatus works on an entirely new principle and consists of a coil-heater fired by a gasoline- burner. The coldest water is taken from the bottom of the radiator, heated, and injected into the top of the cylinder water- jacket or circulated through a small radia- tor in the car body. The hot water can be used for both purposes at the same time if desired by manipulat- ing a small by-pass valve. In any event, the water finds its way back to the bottom of the radiator, thus com- pleting the cycle of operation.

��that the amount of fuel required to run the heater is negligible and that its use in reality saves considerable fuel because it is unnecessary to flood the carburetor when starting the engine. By keeping the en- gine warm, the fuel vaporizes more com- pletely so that its full power is immedi- ately utilized and not wasted in passing out through the muffler. The heater can be applied to any make of automobile, motor truck or ambulance. It can keep the temperature inside of any of these vehicles at from seventy to eighty degrees Fahrenheit. The apparatus is not very difficult to install, for it is compact and self- contained. When a suitable location un- der the hood has been found for the bracket it is bolted on en masse and the proper connec- tions run to the vari- ous necessary points. It has the great advan- tage of being indepen- dent of the engine.

The fuel is carried in a tank on the running-board and is fed under pressure through a special re- ducing-valve to the burner so that the heater may be in operation during a short wait at the curb in the day or at night when the car is garaged.
