ATTORNEY.
Patented Aug. 19, 1930 UNITED STATES CHARLES A. BAUGHMAN, OF FORT WORTH, TEXAS AUTOMATIC ANTIFREEZE SYSTEM Application filed January 28, 1929.
My invention relates to freeze preventing means and more particularly to means for preventing the freezing of radiators of motor vehicles; and the object is to provide simple devices in a radiator which will be actuated automatically to preventfreezing of the radiators and to provide devices for automatically starting and stopping the antifreezing means. Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.
Similar characters of reference are used to indicate the same parts throughout the 5 several views.
Fig. 1 is a diagrammatic view, showing a radiator and a battery and a transfori'ner, the radiator being partly in section.
Fig. 2 is a detail sectional view of the automatic heating means.
Similar characters of reference are used to indicate the same parts throughout the several views.
The drawings show a radiator 1 of ordinary type and a battery 2 of approved type. A metal plate 3 is attached to the bottom of the radiator 1. A thermostat, consisting of a metallic tube 4 and a metallic rod 5 pro jecting through the tube 4, is mounted in and projects through the plate 3 and into the radiator 1. The rod 5 and the tube t must have difl'ere-nt coefiicients of expansion from each other. Current wires 6 and 7 are provided and wire 6 is connected to the batterv 2 and run through the plate 3 and intor.
sulated therefrom and connected to the heating wires 8. Both wires 6 and 7 are electrically connected to the transformer 9. A short wire 10 is run through the plate 3 and insulated therefrom and electrically connected to the heating wires 8. The heating wires 8 are mounted in a cavity in the plate 3. The object of the wires 8 is to heat a portion of the bottom of the radiu- This heat will be transmitted to the water in the radiator. This heating of the water adjacent to the wires 8 will set up a circulation of the water in the radiator, and such circulation of the water warmed by the wires 8, will prevent freezing of the Serial No. 335,681.
water in the radiator. The Wire 10 is connected to a metallic block 11 which is insulated from the plate 3. The block 11 has a contact point 13. The wire 7 is electrically connected to the plate 3 and the plate 3 and tube 4 and rod 5 are in electrical connection, being metal in contact with metal. The rod 5 is so positioned that when the water becomes cold, the thermostat will contract and bring the rod 5 in contact with the con tact point 13 so that a circuit will be closed for heating the wires 8. When the water in the radiator 1 becomes warm, the tube 4 will expand and so draw the rod 5 out of contact with the point 13 and break the circuit. If the water is again cooled towards the freezing point, the thermostat will again contract and bring the rod 5 in contact with the point 13. These operations will be automatic.
The transformer 9 is provided so that when a car is parked, a connection can be made with a supply source of electricity for heating the water in the radiator without using the battery 2. It is apparent that the driver can stop his car and connect the transformer with any supply source and warm the water in the radiator. This can be done at the ordinary filling or service stations.
lVhat I claim is 1. In a motor vehicle provided with a battery and a radiator; means for utilizing said battery to heat the Water in the radiator comprising a metallic plate attached to the lowest point of the radiator and provided with a cavity therein, heating wires mounted in said cavity and insulated from said plate, one current wire electrically connected to said heating wires and to said battery, another current wire electrically connected to said heating wires to cause an electric circuit through said heating wires, a metallic contact block attached to said plate and insulated therefrom, a thermostat mounted in said plate and projected into said radiator and provided with a rod adapted to contact with said block, means electrically connecting said heating wires and said block, and means electrically connecting said thermostat with said battery.
2. In a motor vehicle provided with a radiator; a metallic heating means attached to said radiator at its lowest point, means for electrically connecting said heating means to a supply source of electricity for heating the heating means, a thermostat at tached to said radiator and projected thereiuto and provided with a movable contact making point, a metallic block attached to said radiator and insulated therefrom and 10 provided with a contact point adapted to complete a circuit with said movable contact point, means for electrically connecting said block to said heating means, and means for electrically connecting said thermostat with said supply source of electricity.
In testimony whereof, I set my hand this 93rd day of January. 1929.
CHARLES A. BAUGHMAN.
