Patent drawing Mary Anderson's windshield wiper Related History • The History of the Automobile • Women Inventors Prior to the manufacture of Henry Ford's Model A, Mary Anderson was granted her first patent for a window cleaning device in November of 1903. Her invention could clean snow, rain, or sleet from a windshield by using a handle inside the car. Her goal was to improve driver vision during stormy weather - Mary Anderson invented the windshield wiper. During a trip to New York City, Mary Anderson noticed that streetcar drivers had to open the windows of their cars when it rained in order to see, as a solution she invented a swinging arm device with a rubber blade that was operated by the driver from within the vehicle via a lever. The windsheld wipers became standard equipment on all American cars by 1916.
