Windshield Wipers

Short Description of Topic

Importance

Windshield wipers are now standard in every car made in the world, and they have a crucial function for those of us who need cars to get around during raining weather. Windshield wipers are a common invention in modern times that we take for granted, but the source of their technological advancement stems from the understanding of electrical circuits. Many of the modern electric windshield wipers contain a battery for their power that is a direct current and a field magnet. These components act together to create a rotational motion that you see on the front of your car when you drive in the rain.

History

Windshield wipers first came about around the year 1903, where three separate inventors all filed for patents for the device, Mary Anderson, Robert Douglass, and John Apjohn; however Mary Anderson is usually credited with the invention. Though this was the beginning of the device that we now have electrically controlled in our modern cars, at the time of the patent the "window cleaning device" was manually operated via a lever inside of the car. The main goal of the device is to remove rain, snow, ice, or debris from the windshield of the automobile. The styling of the two windshield wiper slots on the car was made popular in the year 1917 when it was first introduced by the Tri-Continental Corporation. The genesis of the more common intermittent wiper was introduced in 1923 by Raymond Anderson. This was the first time that wipers had been suggested with both an electrical and mechanical component. It took until the year 1963 when Robert Kearns invented his method for intermittent windshield wipers with the electrical component that used the flow of current through a capacitor to time the different speed of wipe. The design proposed by Kearns finally saw its debut in 1969 when the Ford motor company included it in their cars.
