When you think of Venom (not the one in Spiderman Series), you are thinking of reptiles. Also, out of reptiles, you are thinking of snakes. Although the word “snake” is used to call someone fake, the topic here is actually about snakes.
Vipers are venomous snakes, and they are present in almost all parts of the world. The hinged, long “fangs” enable the vipers to bite their prey and inject the Venom.
Vipers are famous for their distinct behavior, deadly Venom, haunting prey tracking and heat-sensing pits. Everyone fears vipers, but snake charmers seemingly don’t worry. However, no one concerns from a Windshield Wiper.
I’m not mentioning the Windshield Wiper workout. I’m referring the real Windshield Wiper. On a rainy day, when your windshield gets wet from the rain-drops, you need to wipe your windshield.
In contrast to a rainy day, dust on the highway also requires cleaning. The accumulated dust requires cleaning too. In all of the circumstances, where you can get tired of wiping, a Windshield Wiper is always here to save your day. Let’s discuss the history, mechanism, types, and wonders of a Windshield Wiper.
Introduction (a formal one)
When you need to wipe or remove ice, debris, rain or snow from the front windshield of a vehicle, a device named Windshield Wiper comes to your aid. Besides, to your surprise, Windshield Wiper is usually a legal requirement for your cars.
Almost all vehicles, which operate on a petrol/diesel engine, have a Windshield Wiper on the front. Instead of mentioning the references from a legend, you can easily witness a Windshield Wiper.
On buses, cars, trucks, watercraft, train locomotives, and even aircraft, a Windshield Wiper is present. Windshield Wiper is a common, yet essential thing.
On 6th of August, 1896, the earliest patent for a Windshield Wiper was filed by George J. Capewell, a resident of Hartford. For “cars, locomotives and such land-vehicles,” he invented an automatic, motorized wiper.
Other inventors around the same time, claimed patents for Windshield Wiper, the story is skipped here for the sake of keeping the writing short. Many inventors invented their versions of Windshield Wiper, and this rectified the shortcomings.
For the noble purpose of cleaning any impediments to visibility, a Windshield Wiper blade swings back and forth on the shield. Consisting of a metal arm, a long rubber blade is attached to one end.
The other end is on the pivot. In the vehicles from the 70s to present, the Windshield Wiper is adjustable to speed and intermittent settings. Most of the cars have two Windshield Wipers. However, some of the vehicles have pantograph arms, numbering from one to more.
Power Source for a Windshield Wiper
According to the Law of conservation of energy, energy can neither be created nor be destroyed. And power is the measure of energy per unit time. best Windshield Wiper requires power to clean your windshield.
You can supply a Windshield Wiper with power using several ways. The “number of ways” is not discussed here. Most of the new Windshield Wipers get their energy from an electric motor. A series of mechanical parts, connect to run a Windshield Wiper.
More on the Power Source for a Windshield Wiper
Vehicles which use air-operated brakes can use pneumatic wipers. Pressurized air in a small amount is provided to an air operated motor. This air operated the motor, in turn, produces the wiper. A vacuum motor, run by a manifold vacuum, was used in early models of Windshield Wipers. However, the shortcomings of this process stopped their widespread use. Hydraulically-driven wipers were also used in the past. A purely mechanical Windshield Wiper was once incorporated in earlier Citroën 2CV.
The Geometry of a Windshield Wiper
From ancient Greece to the modern world, no one can deny the importance of geometry. We now have fancy uses of geometry, measuring the golden ratio of a human face. Anyways, the topic wants attention for a Windshield Wiper. Most of the Windshield Wipers are of radial type, a single arm attached to a motor. Such Windshield Wiper is used in almost all standard vehicles. There are many possibilities when it comes to the geometry of a Windshield Wiper.
Other Applications of a Windshield Wiper in Automotive
Being an ingenious invention, a Windshield Wiper has many uses.
The back window of an automotive also gets dusty, requiring attention. The back window Windshield Wiper was first offered in the 40s. Over time, rear wipers became popular. Such cars, which accumulate dust at the back window, come with a rear wiper.
Headlights provide the necessary light to travel. We must take care of our headlamps. Headlight Wipers help us take care of headlights. But the use of headlight wipers is no more. Fluid sprays wash the lights, being low cost.
Other Features Incorporated with a Windshield Wiper
A tank filled with a mixture of alcohol, water and detergent (called “windscreen washer fluid”) operates together with Windshield Wiper. A pump provides the fluid to the screen. Small nozzles spray the liquid on the screen.
Fluid can be delivered more efficiently with the use of a fluid oscillator. However, a new system is introduced. The fluid is now provided by the rubber blade of a Windshield Wiper. The wiper itself wipes the liquid, clearing the windshield in the result.
Some bigger cars use a mechanism to hide the wipers using an automatic circuitry. The wipers, when idle, are turned to the bottom of the windshield. The wipers are still in sight, but not covering the whole windshield.
To completely hide the powers from the view of drivers, a different method is used. The windscreen is slightly big, extending below the sight of the driver. The wipers are settled there when there is no use. The bigger windshield makes the wipers invisible to the driver.
A Beautiful, Rain-sensing Wiper
Sensors have already changed our lives. The heat, precipitation, and pressure sensors are to name a few. We now totally rely on the data provided by the sensors.
The sensors have also proved their effectiveness with a Windshield Wiper. A rain sensor is incorporated with a Windshield Wiper.
Although the wiper can be manually controlled, the wiper with a rain sensor automatically adjusts its speed. Many of the mainstream automobile companies now provide rain-sensing Windshield Wipers.
A Wonderful Alternative
A “clear view screen” design is used on ships. This design does not use a rubber blade. The windscreen has two parts. The outer, circular portion is spun at high speeds. The high speed turned sheds the water efficiently.
To save the aircraft from weight and drag, high-speed aircraft may use “bleed air.” It uses a constant supply of compressed air from the turbine engine to remove water. Rain-X and other water repellent glass increase the functionality of this bladeless method.
Wipers are essential for your safety. Rain and dust lower your ability to see the road. If your Windshield Wiper is out of order, you are also not out of danger. Take great care of your Windshield Wiper to save yourself from harm. Take time to check your windshield wiper, and travel without any worries.
