The Past Of The wiper blades And How It Began To Reign The Planet.

Posted: May 13, 2010 | By: | In: Autos and More

The sort of replacement wiper blades we presently recognise today are all made from the build patented in 1903 by a Mrs Mary Anderson, of Birmingham, Alabama, United States. By contrast to today’s high tech wipers these were a bit primitive. The basic device consisted of a hand crank which was used by the driver from within the cab. Mary Anderson was propelled to create the first wipers on a trip to New York City where she took account of the tram drivers cleaning their wind screens by hand. Once the basic wiper blade model was engineered it was left to other means to actuate the wiper blade arm across the wind screen. The first blossoming in this area was the vacuum system which administered force through what is called a vacuum pump. This appliance utilised the difference in air pressure between the inside and the outside of the intake manifold to produce a vacuum force.

This development was thanks to the advent of the industrial revolution when Henry Ford started the Ford Motor Company and initiated a action of generating millions of auto mobiles with wipers fixed as standard. The internal combustion engine was in many ways the catalyst which propelled the wind screen wiper into its contemporary standing in society. Today replacement wiper blades are truly ubiquitous discovered on every type of vehicle imaginable from the basic car, to aeroplanes, helicopters, boats and even hover craft. The blemish with this set up back then was the speed of the wiper blade was bounded by the amount of force generated from the vacuum. So at high speeds this was inversely proportional and the replacement wiper blades came to a complete stop, unlike today’s modern electrically driven models. When the AC motor was revved the wipers would go at an incredible rate but when the engine was compromised going up a hill they would all but stop. This design has since been superseded by the superior electric replacement wiper blades thanks to the engineering of the battery where energy can be accumulated and dispensed at will.

By the mid nineteen sixties the vacuum powered replacement wiper blades was all but deceased and electric wipers were attached as standard. Today the modern electric replacement wiper blades has many different functional settings, these include a body of speed settings to suit the prevailing weather types and intermittent speed settings for when it is only spitting. Another innovation is the rain sensing system developed by Citroen of France in the nineteen seventies and fitted to its Maserati. This approach didn’t sense the rain directly but instead sensed the amount of resistance encountered when wiping the windscreen, more resistance indicated less rain water therefore the battery produced less power. When it rained the wiper blade would bear down on less resistance and so the wiper blade would go at a faster rate accordingly. The wiper blade has to be by hand turned on and off as well prior to use. Today’s rain sensing technology is better; it will turn on the wipers itself and will adjust the speed of the wipers by directly sensing the level of rain fall.
