NEW WINDSHIELD CLEANER USES WIND PRESSURE (Oct, 1923)
NEW WINDSHIELD CLEANER USES WIND PRESSURE
A new windshield cleaner, that is entirely automatic in action, utilizes the wind pressure against the windshield when the car is in motion, as a means of keeping the glass clear in rainy weather. It consists of a nozzle-shaped piece of metal, which is attached to the windshield with a suitable adhesive and which directs a current of air against the glass, causing the rain spots to merge and run off at the bottom.
The inventor clearly does not live in a part of the world where there is snow, or dust, or muddy water, or ice, or anything other than clear rain.
