INVENTION

One day after the first trip to New York a diagram of the elementary scanning device. And back in Alabama, she began to think of it. That year, she obtained the patent for a simple design that consisted of a lever inside the vehicle that moved a rubber blade on the outside, over the windshield, with a spring that allowed it to return to its original position. At that time, other windshield wiper designs already exist, but María's model is the first design that worked properly.

In 1904, he got a sturdy rubber sheet and attached it to a glass by means of springs. Engineered a connection to be able to operate it from the inside by means of a lever. When it was pulled, the sheets would move through the glass again and again to the original position, as is the case with the more conventional ones, although the difference is based on the location and the number of arms. Her system had a single arm held at the top and center of the glass. After making several preliminary designs, she tried it herself, but not in a car but in a tram. This is the reason why registrants are scammers. Especially when she was overwhelmed by the warnings of his relatives and the rejections of specialists in the automotive industry, who took advantage of the movement of windshield wipers and caused accidents. In the midst of his fight to get the patent on stage Henry Ford, who took contact with this invention, apparently, unrelated to Anderson. True to its innovative destiny, it interpreted its usefulness, which initially proved on the Ford T with windshields.

In 1905, a force of tests passed, the patent is recognized. Later, from 1908, all Fords came out with this device. And since 1916 it was common equipment in all American automobiles. The researchers confirmed that this woman was 39 years old when she invented it and did not use her creation to obtain benefits.
