AUTOMOBILE WINDSHIELD HEATER Filed March 5, 1930 (lttomegs'.
- Windshields whic Tatented May 2, 1933 UNITED STATES PATENT OFFICE AUTOMOBILE WINDSHIELD HEATER.
Application filed March 3,
The present invention relates to improvements in automobile windshield heaters and has for an object to provide an improved windshield heater acting to prevent ice from forming upon the windshield glass while driving through snow or sleet.
Another object of the present invention is to provide an improved heating device which will result in imparting to the windshield glass an even and uniform heat throughout the entire surface, thereby lessening the liability of cracking the glass.
A further object of the invention is to provide an improved heater having sufficient heating surface and capacity to raise the temperature within the vehicle.
A still further object of the invention is to provide an im roved heating system for will take advantage of the heat imparted to the water in the cooling system and acting to assist the radiator to cool such water.
With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claim appended hereto.
In the drawing, wherein like symbols refer to like or corresponding parts throughout the several views:
Figure 1 is a fragmentary longitudinal sectional view through a vehicle equipped with the improved heating system.
Figure 2 is a front elevation, with parts shown in section, of the improved heating unit.
Figure 3 is a cross section taken on the line 33 of Figure 2 and shown on an enlarged scale, and
Figure 4 is a similar view showing a slight modification. Referring more particularly to the drawing, 10 designates the radiator of an automobile; 11 the hood thereof; 12 the dashboard, and 13 the windshield.
The internal combustion engine is shown at 14. The engine is provided with a water jacket in accordance with customary practice. The water jacket is provided with a drain cook 15 which forms a convenient con- 1930. Serial No. 432,816.
nection for coupling the pipes or tubes of the improved system.
In accordance with the invention a pipe 16 is made to extend between the drain connection 15 and the pump well 17, which is disposed above the pump 18 having a pulley 19 adapted to be connected by a belt, such as the fan belt usually found on automobiles. The discharge of the pump has connected therewith a pipe or flexible tube 20, which is the supply tube. The return pipe or flexible tube is indicated at 21. Both the tubes 20 and 21 are connected to the improved heating device; and the tube 21 is connected to the water circulatory system at any desired point. It may be connected to the water jacket of the engine or to the drain connection 15.
The conditions are satisfied if the pump 18 may draw hot water from the water .70
erably inside the vehicle or in the rear of the windshield glass 13. This frame is preferably substantially rectangular so as to provide an interior open space for clear visibility through the windshield glass.
As shown in Figure 3, the frame is com- 5 posed of a preferably elongated tube. The tube is elongated vertically and supported preferably by the frame 23 of the windshield. For this purpose perforated lugs 24 may be connected to the tube or. frame 22 and receive screws or other fastenings 25 which are threaded into the windshield frame 23.
As shown in Figure 2, a partition 26 is shown as extending across the tube 22, preferably at one corner point, and the flexible pipes 20 and 21 are coupled to tlTe tube 22 at opposite sides of such partition 26.
The inlet tube 20 carrying the hot water is preferably connected at the upper side of 00 the partition 26. The heated water will tend to rise in the vertical leg of the tube 22 and pass about across the upper horizontal leg 22, becoming gradually cooled as it circulates through the tube. The colder water will descend through the opposite vertical leg, and flow across the lower horizontal leg to the outlet tube 21; thence back by way of the pipe 21 to the water system.
Instead of supplying the lugs 24 and fastening the heating device to the windshield 'frame 23 as shown in Figure 3, supporting strips 27 may becarried forwardly of the frame 22 and cemented or otherwise secured directly to the windshield glass 13.
A further modification is shown in Figure 4, where the windshield frame 24 may be made of tubular form and provided with the heating channel 28 extending all about the glass 13. The hot water is circulated in this channel or tube 28.
In accordance with the invention, the hot water for the heating system is taken from the cooling system, passed through the heating device and returned to the cooling system, cooler than when it left. This is a gain instead of a loss to general operating.
It will be noted that only elements of the operation of the car are employed which do not detract from the efiiciency of such units. With such devices as electric heat-- ers, the battery is severely drawn upon, and in cold or stormy weather the battery is almost always in a weakened condition. The improved system acts as an aid to the cooling system of the vehicle.
It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claim.
What is claimed is A heater attachment for automobile windshield, comprising a tubular frame shaped to the configuration of the marginal edge portion of a windshield, supporting means on. the tubular frame for attaching the same to the side of the windshield, said tubular frame having a transverse partition and an outlet at the other side of the partitlon, water circuit pipes connected to said. inlet and outlet of the tubular frame and adapted for connection in the water cooling system of the automobile, for obtaining heated water therefrom, and Water lifting means in circuit with said water circuit pipes for raising the water from the automobile cooling system through the tubular frame.
