According to the documented accounts, Mary was riding in her
carriage during a stormy night. She had to stop the carriage
periodically while travelling in order to clean the windscreen.
She then imagined a device that cleans the window from the
inside as a result of this. At this point, the idea of a mechanical
wiper was raised. In 1903, Mary Anderson is frequently given
credit for creating the first practical window wiper. Later, the
cars of that era began to include these antiquated windshield
wipers. She also referred to her concept as a "window cleaning
equipment.
More over a century ago, reduced visibility from rain or snow
posed serious dangers to the safety of both drivers and
passengers. Driving in rainy and foggy weather therefore
became simple after the development of windshield wipers.
The technology that makes windshield wipers work has
undergone significant changes over time. They were operated
using a variety of mechanisms. The wipers being powered was
the original concept. Early powered windshield wiper models
relied on vacuum and were driven by the engine's manifold.
However, this had certain drawbacks. Engine manifold vacuum
changes with speed and throttle input and is barely detectable
at full throttle. This caused the wipers to move at various
speeds and occasionally stop moving altogether
