The wiper is an inconspicuous car accessory, but in rainy and snowy days, the wiper is definitely an artifact among artifacts. Although the wiper is an automobile accessory, it was not born at the same time as the automobile, and the wiper has saved countless lives from scratch. Now let's have a good understanding of the birth process of the wiper.
Before the 19th century, people used a mixed liquid such as onion and carrot to prevent rainy days and some special situations, but it was not popular because of its bad smell and poor effect. Until 192, a man named Mary? Anderson's rich girl invented the first real wiper.
in 192, Mary? Anderson was caught in a sudden heavy rain on his way, so the driver couldn't see the road ahead clearly and had to wipe the rain on the windshield with a rag. While the driver was driving and wiping the rain with a rag, suddenly a cyclist came out in front of him. The driver hurriedly slammed the steering wheel and ran into a tree. Mary was injured on the spot and was taken to the hospital. And 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, and a year later he invented a wiper and installed it in his car. Mary? The principle of wiper invented by Anderson is that a sponge is tied to a steel rod with a hole through the car glass, and the sponge clinging to the glass can wipe the rain by turning the lever. However, in rainy days, it is very dangerous for the driver to drive the vehicle while turning the lever by hand.
so, Mary? Anderson invented the rotating rod with clockwork on the original basis, and the wiper can automatically wipe the rain many times after the last effort. Later, she named this rain wiper as a wiper, and applied for an invention patent, the first wiper in the world.
