A top quality wiper blade is really important for negotiating the roads in these busy times. Planes and trains have wiperblades fitted to them too, almost all vehicles have them. A basic idea for a wiperblade was the brainchild of an American investor by the name of J. H. Apjohn. Also in 1903, Mary Anderson came up with a modification of the blade by using a ‘swinging arm’ mechanism. Spraying fluid onto the screen through a pump installed under the bonnet is helpful alongside the wiperblade in gaining good visibility. Problems can arise when water is used in the pump, this is fine in summer but it can freeze in the cold weather and will be useless. As car manufacturing became more sophisticated they added wipers to headlights to ensure that they were kept clean. One of the most recent advances in the world of wiperbades is the development of water sensitive blades that operate once it begins to rain.
