Wiper patent expires

Wipers are not very conspicuous as auto parts, but in rainy and snowy days, wipers are definitely artifacts among artifacts. Although wipers are auto parts, they were not born at the same time as cars. Wipers have saved countless lives from scratch. Now let's have a good understanding of the birth process of wiper.

Before the19th century, people used mixed liquids such as onions and carrots to prevent rainy days and some special situations, but it was not popular because of its bad smell and poor effect. Until 1902, a woman named Mary? Anderson's rich girl invented the first real wiper.

At 1902, Mary? Anderson was caught in a sudden heavy rain on the way. The driver couldn't see the road ahead clearly, so he had to wipe the rain on the windshield with a rag. When the driver was driving to wipe the rain with a rag, suddenly a cyclist appeared in front of him. The driver slammed the steering wheel and ran into a tree. Mary was injured on the spot and was taken to the hospital. What about Mary? Anderson's father died in a car accident because the windshield was blurred in rainy days, so Mary? Anderson began to find a way to solve this problem.

After discharge, Mary? Anderson began to study the wiper. A year later, he invented a wiper and installed it on his car. Mary? The principle of wiper invented by Anderson is to tie the sponge to a steel rod with holes through the car glass. By turning the lever, the sponge close to the glass can wipe the rain. However, in rainy days, it is very dangerous for the driver to drive the vehicle while turning the gear lever by hand.

So, Mary, Anderson invented a rotating rod with a clockwork on the original basis. After the last effort, the wiper can automatically wipe the rain many times. Later, she named the wiper as the wiper, and applied for an invention patent, the first wiper in the world.
