In the end, American inventor Mary Anderson received credit for the first operational windshield wiper, back in 1903. Anderson’s “window cleaning device” used a rubber squeegee blade on an arm, operated via a hand-cranked lever from inside the vehicle. The windshield wiper had reached mass production phase!
- The automatic wiper blades were eventually invented in 1917 when electric motors were incorporated in the top center of the windshield in order for the wiper to arc down on top of the hood of the vehicle in a rainbow or semi-circular shape.
Who invented the windshield wiper blades?
Windshield Wiper Invented In 1902 By A Woman Who Didn’t Drive Entrepreneur Mary Anderson thought it made no sense that New York streetcar drivers had to keep jumping off to clean snow from the windshield. She soon won a patent for her ‘window cleaning device.’
What did people use before wipers?
The history of the windshield wiper began with the invention of the automobile. Most transportation vehicles did not have wipers. Horse-drawn carriages and trucks moved at slow speeds, and glass was not needed to protect the driver or passengers or to act as a windbreak. The first windshield wipers were brushes.
When did they put windshield wipers in cars?
She filed for a patent in 1903. It was a giant leap forward in vehicle safety design. Unfortunately, for almost 35 years car companies didn’t offer windshield wipers as standard equipment. It wasn’t until the 1940s that automotive manufacturers began including wipers on all their products.
Did the first car invented have windshield wipers?
William M. Folberth, an inventor, patented the first automatic, non-hand-driven windshield wipers in 1919. These automatic windshield wipers used a vacuum-powered system to clear the windshield, which became standard equipment on automobiles.
Is Mary Anderson still alive?
(C) Mechanical type of wind screen wiper were used in the old time vehicles. Explanation: To begin with, a windshield wiper was invented back in 1896 by George J. Capewell of Hartford Connecticut.
What year did intermittent wipers come out?
In 1969, the Ford Motor Company introduced the first electronic intermittent windshield wiper.
How many years ago was the first car made?
The year 1886 is regarded as the birth year of the car when German inventor Karl Benz patented his Benz Patent-Motorwagen. Cars became widely available in the early 20th century. One of the first cars accessible to the masses was the 1908 Model T, an American car manufactured by the Ford Motor Company.
What was the first windshield wiper?
Windshield Wiper Origins In the end, American inventor Mary Anderson received credit for the first operational windshield wiper, back in 1903. Anderson’s “window cleaning device” used a rubber squeegee blade on an arm, operated via a hand-cranked lever from inside the vehicle.
Why did Mary Anderson not make any money from her patent?
743,801 to a Birmingham, Alabama woman named Mary Anderson for her “window cleaning device for electric cars and other vehicles to remove snow, ice or sleet from the window.” When she received her patent, Anderson tried to sell it to a Canadian manufacturing firm, but the company refused: The device had no practical
When was the first windshield invented?
The first windshields were placed on cars in 1904. These were simply horizontally-divided pieces of plate glass. They type of glass that you would find a typical single page window in your home.
A Brief History of the Windshield Wiper Montgomery AL
The deadline for submissions is May 31st, 2017. In the early days of automobile travel, people quickly understood that vision in the rain would be an issue, and that sticking one’s head out the window to see was not a practical option in most cases. The need for anything to wipe precipitation from a car’s windscreen was unavoidable.
Windshield Wiper Origins
In addition to a Polish concert pianist named Jozef Hofmann, the initial ideas for windshield wipers were ascribed to Mills Munitions, which was based in the English city of Birmingham. In reality, at least three different inventors filed patent applications for windshield wiper-type devices around the same time period. In the end, it was an American inventor, Mary Anderson, who was credited with developing the world’s first functional windshield wiper in 1903. An arm mounted with a rubber squeegee blade on it was controlled by a hand-cranked lever from inside the car, according to Anderson’s ‘window washing apparatus.’ The windshield wiper of 1903 was surprisingly similar to what we are accustomed to now, with the exception of the manual hand-cranked driving system.
The windshield wiper had reached the stage of mass manufacture!
Moving into the Modern Age
After being superseded by a system that utilizes engine vacuum to operate the mechanism in the early 1920s, the hand-cranked wiper was no longer in use. The vacuum wipers were excellent, except that their speed varied depending on the load and speed of the engine. After being replaced with an electric drive in the early 1960s, vacuum wipers were eventually phased out, and the intermittent wiper was introduced in the mid 1960s (and was initially rejected by Ford).
- Whippletree is a term used to refer to the coupling of springs and a segmented arm that allows a windshield wiper to distribute its pressure evenly over the windshield.

The Evolution of Wind Shield Wipers – A Patent History
Mary Anderson, the Hall of Fame creator of the windshield wiper, was born on this day in 1898. One of the earliest trips made by a woman from Alabama to New York City occurs in the early twentieth century; the cold and stormy weather she encountered, along with her observations of how it affected her travels, resulted in the invention of a technology that the vast majority of car owners take for granted today. Because of the efforts of Hall of Fame inventor Mary Anderson, who designed the windshield wiper more than a century ago, driver visibility when driving in the rain or snow would be substantially reduced, posing significant hazards to both the driver and the passengers.
Although we may be glad for windshield wipers when a strong rain arrives unexpectedly during our drive, we all take them for granted.
The fascinating story of Mary Anderson’s development of the windshield wiper combines a clever solution to a frequent problem as well as the construction of a technology that was decades ahead of its time in terms of functionality.
Getting a Clear View of the Road Ahead
Mary Anderson received U.S. Patent No. 743801, entitled ‘Window-Cleaning Device,’ on November 10, 1903, which she used to create her invention. While visiting New York City at the turn of the twentieth century, Mary Anderson, born in 1866 and originally from Birmingham, AL, who worked as a real estate developer, cattle rancher, and winemaker at various stages in her life, was riding a streetcar on a streetcar. It was a gloomy day, and the freezing rain that had fallen had made seeing through the windshield very impossible for the streetcar driver.
- Anderson, on the other hand, was exposed to a cool blast of air for the first time as the driver lifted a window pane to peer out the window and assess the road conditions.
- It also caused some pain for the passengers who were seated towards the front of the bus, as well as the driver, whose sight was not significantly better when he stuck his head outside in the severe weather.
- Anderson began working on a concept for a windshield wiper that could be operated by a driver from within a car, which would increase visibility while reducing disagreeable encounters with the wintry environment almost immediately.
- The prototype was eventually approved.
- Anderson received U.S.
- 743,801, which was entitled Window-Cleaning Device, from the United States Patent and Trademark Office on November 10, 1903.
- Despite this, many people were critical of Anderson’s invention, with some even claiming that the wiper would prove to be a harmful distraction for drivers on the road.
- She was never able to secure any investment in the idea; one of her most significant rejections came from a Canadian manufacturer who did not see any practical application for the innovation.
Despite the fact that windshield wipers were standard equipment on most automobiles by 1916, her patent expired before she could collect any royalties or licensing fees for her invention.
Further Improvements to Windshield Wipers
Obviously, the hand-operated lever system described in Anderson’s ‘801 patent is a far way from the variable speed automated wiper systems that are now used in the majority of modern automobiles. Many of the modifications made to Anderson’s design by subsequent innovators made it considerably easier for the expanding number of American vehicle drivers to operate their windshield wipers than it had previously been. Another female inventor had an impact on the early development of windshield wipers by inventing a patented design.
- The device is said to be the world’s first automated windshield wiper to be powered only by electrical power.
- It’s based on the United States patent number 1362175, which is named ‘Cleaner for Windshields and the Like.’ The first automatic windshield wipers that employ blades were invented by a pair of Cleveland, Ohio, brothers named William M.
- Driving motion for the wipers was given by the brothers’ innovation, which sent exhaust air from the engine manifold to an actuator that moved the wiper blade back and forth across the windshield as the engine was running.
- 1,420,538, titled ‘Windshield Cleaner,’ which was awarded to the brothers on June 20, 1922, may be seen a lot of this technique in action.
- It was wanted to have a more uniform wiping pace.
- Oishei of Buffalo, New York, and has gone on to become one of the most successful windshield wiper companies in history.
- Despite the fact that the biker survived, Oishei was motivated to develop a more effective wiper system.
The working arm is spring-loaded to guarantee that the wiper applies a constant amount of force to the glass surface at all times.
Following that, Robert Kearns of Detroit, Michigan, developed the intermittent wiper system, which was a game-changing breakthrough in the realm of windshield wiper technology.
He is credited with being inspired to develop his own windshield wiper as a result of the unexpected event.
However, Kearns was awarded a number of patents in the field of windshield wiper technology, the most notable of which was U.S.
3,351,836, entitled ‘Windshield Wiper System With Intermittent Operation.’ Kearns demonstrated his invention to the Ford Motor Company but was never compensated for his efforts.
He would later pursue cases against many automobile manufacturers, winning tens of millions of dollars in settlements, but only after decades of court fights that had a negative influence on his mental health and personal life, he would be able to retire.
According to U.S. Patent 3351836, entitled ‘Windshield Wiper System With Intermittent Operation,’ this invention was discovered.
Current R D in Windshield Wiper Technologies
Because of the standard windshield wiper technologies that are already ubiquitous in today’s automobiles, it is quite straightforward to maintain good driver visibility even in adverse weather situations. Everything from changing a wiper blade to turning on a car is among the most straightforward chores a car owner can undertake. But there are still some cutting-edge technologies being developed in this industry today. For example, the British manufacturer McLaren Automotive is investigating the use of ultrasonic force fields to clean debris from windshields, perhaps eliminating the need for standard wiper blades entirely.

The Store of Automotive Windshield Wipers
It’s amazing how many things we take for granted. For example, we take it for granted that when it rains or snows, our windshield wipers will keep the windshield sufficiently clear to allow us to continue driving. Windshield wipers, on the other hand, were not always standard. They were not available on early automobiles. They were unnecessary in a horse-drawn carriage, so why were they required in a horseless carriage? For starters, a motorist need some protection from those gal-darned gnats, and a driver who was traveling at a reasonable pace required a windbreak, and new-fangled drivers required the ability to see where they were directing their vehicles.
- Cars, on the other hand, did not give this second viewpoint.
- To keep their little piece of vertical glass clean during bad weather, it is reported that they used a piece of plugtobacco, a bit of potato or a piece of carrot or an onion, or pretty much whatever else they could think of to bring along.
- An Irish-born inventor named J.
- Apjohn is credited with being the first known developer of an actual windshield wiper.
- However, as is so frequently the case, another inventor was working on a solution at the same time and is credited with the invention of the first American wipers as well as the first operable windshield wiper in the world.
- A trolley car driver battling to keep his windshield clear during a sleet storm caught her attention during a visit to New York City in 1902.
- Riders, on the other hand, were dissatisfied with the outcome.
A spindle was threaded through a hole in the windshield frame, connecting the external rubber wiping blade to the inside handle via a hole in the windshield frame.
Her brilliant design before the Model T, at a time when automobiles were not yet widely used.
By 1916, however, her idea was standard equipment in all automobiles manufactured in the United States.
The product, on the other hand, was not a commercial success.
A number of other inventors recognized the inherent danger in this practice, and they came up with motorized solutions, such as a one-armed blade installed in the top center of the windshield (an invention of Hawaiian dentist Dr.
Using a manual windshield wiper on a 1920 Kissel Gold Bug is a fun and unique experience.
The driver, J.R.
He tracked out a retired electrical engineer named John W.
In fine weather, it was stored in the car’s tool box.
By moving the handle back and forth, the blade was able to clean the windshield completely.
In 1921, American inventor William Folberth received a patent for a single-blade wiper that was operated by suction from the engine’s intake manifold, rather than by electricity.
When the throttle was opened all the way, the engine vacuum fell, and the wipers either slowed down or stopped completely.
The majority of wipers on automobiles made prior to 1920 were paired and secured at the top of the windshield.
After a Trico salesperson fitted a manual wiper on Ford’s own car, Henry Ford, who had previously been adamant about not adding any additional ‘gadgets’ to automobiles, finally saw the light.
By the mid-thirties, Trico had created the first windshield-washer system, and by the late-forties, it had introduced the first windshield-washer/windshield-wiper combo system.
In most cases, they were powered by an electric pump.
Nowadays, this is done through the use of an electronic timer, but back in the day, a tiny cylinder attached to a switch produced the necessary delay as the vacuum seeped out of the cylinder and into the air.
An engineering professor, after seeing that the human eye blinks just every few seconds rather than continually, came up with the notion of using intermittent power wipers to clear away debris from a windshield or windshield wipers.
When he first exhibited the system to Ford in 1963, he hoped that the company would license his technology (which was patented in 1967 and used a solid-state circuit) that allowed drivers to choose between a number of different delays between two successive swipes.
According to the 2008 documentary ‘Flash of Genius,’ after many years of litigation and the hiring and firing of numerous law firms, federal juries awarded Ford damages of slightly more than $10 million for unintentional patent infringement and Chrysler damages of roughly $19 million for unintentional patent infringement.
- Saab introduced the first headlight wipers in 1970, while Citroen introduced the first rain-sensitive intermittent wipers in 1971.
- The engine monitored the amount of resistance the wipers encountered on their initial swipe; a little amount of resistance indicated that the windshield was reasonably dry, whereas a large amount of resistance showed that the windshield was saturated with moisture.
- These sensor wipers were first launched by Cadillac in 1996, but they are now available on a wide range of other automobiles.
- With the passage of time and the advancement of electronic gadgetry, wipers began to emerge on the front and rear windshields, as well as on the headlights of automobiles.
- As a result, we can simply assume that wipers, which are no longer considered optional equipment, will be there when we require them.

A Quick History of Windshield Wipers
Are you interested in the history of windshield wipers? Was there ever a time when this most fundamental — and obviously required — piece of car safety equipment wasn’t a standard feature on nearly every vehicle on the road? Even more surprising is that not only is the answer to that question ‘yes,’ but there have also been a number of advancements and developments that have helped steer the basic wiper to its current form. Let’s take a short look at the road that has been traveled thus far, as well as the rationale behind the present wiper design.
It Began on a Trolley
Prior to automobiles, there were other vehicles that required the ability to see ahead of them as well. While it is true that the history of windshield wipers begins on the trolley tracks, rather than the highway, it is also true that a woman named Mary Anderson was taken aback when she witnessed how difficult it was for a New York City streetcar driver to keep the glass in front of him clear on a stormy day. Anderson’s design failed to find an audience, and despite patenting the manually operated technology in 1903, she would never get a financial return on her investment before the patent’s trade protection expired.
Douglass who concentrated on trains) would have their work overlooked by the larger industry as time progressed as well.
However, it would be the spring-tension rubber blades developed by Tri-Continental Corporation in 1917, as well as the vacuum-powered automated wiper mechanism that would ultimately dominate the next several decades of passenger car production, which would ultimately lead to the invention of the automatic wiper mechanism in 1922.
When Robert Kearns devised intermittent timing for windshield wipers, the history of windshield wipers was a little more dramatic. Kearns would subsequently sue Ford, claiming that the company had stolen his innovation without giving him credit after he had presented it to them in 1963. The transition away from vacuum power began throughout this decade as well. One problem of utilizing a vacuum to move wipers was that it was not powerful enough at higher engine speeds to resist the force of the wind blowing against the wiper blades themselves, which made driving in the rain extremely risky in many situations.
Automatic for the People
Currently, windshield wipers have progressed to the point where they can employ a sensor to determine the quantity of rain on a windshield, rather than the more typical intermittent approach, and they can also conceal themselves beneath the hood cowl for improved aerodynamics when not in use. The rubber used in the blades has also been enhanced, with ingredients such as Teflon and silicone being used to make them more resistant to damage, let them to move more freely, and prevent them from freezing.

From Basic Brushes to Heated Blades – The History of Windshield Wipers
What if I told you that windshield wipers were considered a necessary safety element in autos as early as 1903? Of course, the first models of wipers were nothing like the ones that are currently available – this component of your car has gone a long way since then! Moreover, we are confident that the creator Mary Anderson could never have envisaged heated wiper blades such as those offered by Everblades!
Windshield Wipers in 1903
Mary Anderson, from Alabama, is credited with being the first person in the world to design windshield wipers. Her invention was defined as a ‘window cleaning device for electric automobiles and other vehicles to remove snow, ice, and sleet from the glass’ in her patent, which she filed in 2012. It was unfortunate for Mary that she was never able to reap the benefits of her creation. This was also the same year that J.H. Apjohn filed for a patent in the United Kingdom for a similar device that employed two brushes that moved up and down to keep the windshield clear.
However, the windshield wipers were designed, they were a great convenience for drivers everywhere since they eliminated the need to drive with your head hanging out the window in poor weather!
Electric Windshield Wipers in 1917
In 1917, the development of windshield wipers made significant strides ahead. The driver was required to manage steering, shifting, and controlling the automobile all at the same time when this vehicle function was previously available only through manual operation. It appears to be a difficult task, doesn’t it? It is for this reason that an automated electrical system is required to make windshield wipers more convenient. In 1917, Charlotte Bridgwood came up with the idea for the ‘Storm Windshield Cleaner.’ Rather than blades, the new design made use of rollers, which were propelled by the engine and so provided an automated wiping motion.
Brigwood’s automatic wipers began to acquire popularity in 1921, despite the fact that she was not given proper credit for the innovation until later.
Windshield wipers are an essential part of any automobile, regardless of who invented the great advances that make driving safer and more convenient for everyone.
Originally conceived as a novel way to enhance driving conditions, windshield wipers have evolved into a little-considered car component that we all come to take for granted today.
The Biggest Step for Windshield Wipers – Heated Wiper Blades!
The development of windshield wipers made driving in the rain and snow substantially simpler, but Everblades takes it to a whole new level! No one in 1903 enjoyed poking their head out the side window of their car to gain a clear view, and no one now enjoys stepping out into the bitter cold to brush the snow off the wiper blades. Neither did the people who lived in 1903. Everblades, like Mary Anderson and Charlotte Bridgwood, understood the inconvenient nature of driving and set out to discover a more convenient alternative.
Everblades Windshield Wipers combine premium materials with a heated squeegee and wiper arm technology to improve driving safety while also increasing productivity on the road.

On June 19, 2015, The News Wheel published an article about the history of automobiles, the history of windshield wipers, and the history of windshield wipers. Windshield wipers are essential for driving safety on the open road. If you find yourself traveling in a downpour, it is natural to switch on the windshield wipers on your car. When it comes to current cars, windshield wipers are a standard (and often necessary) equipment (with the possible exception of McLarens), but this wasn’t always the case.
- Mary Anderson, a real estate entrepreneur, cattle rancher, and winemaker, was the first person to patent a windshield wiper in 1903.
- In the middle of a thunderstorm in New York City, Anderson noted that a streetcar operator was straining to see because of severely poor vision, prompting him to open his window and poke his head out the window.
- This manual system, which used a lever to move a series of wood and rubber arms, assisted in clearing snow, rain, and debris off the road.
- It wasn’t until 1916 that windshield wipers became standard equipment on the majority of automobiles, paving the way for future technological breakthroughs in the process.
- Folberth received a patent for the world’s first automated, non-hand-driven windshield wipers.
- Until the 1960s, when the usage of intermittent wipers became increasingly prevalent, this vacuum-powered device was commonly utilized.
- Kearns’ concept was brought to the attention of the Ford Motor Company when he recommended that the design be manufactured by them.
- Windshield wipers are now standard equipment on most automobiles, and a wide range of alternatives are available.
- With this technology, you may be assured that your perspective of the road will remain clear.

History of the windshield wiper blade
It’s incredible that someone had to come up with the idea for a windshield wiper blade, let alone that automobiles didn’t have them until they were conceived. Following the incident in which she witnessed a trolley car driver pause to wipe sleet off the windscreen, Mary Anderson evidently couldn’t take it any longer. So she came up with the idea and applied for a patent in the United States for the wiper blades we know today. She never received a single penny for her idea. It appears that Mary Anderson simply couldn’t find any buyers for her ground-breaking invention, according to the History Channel: ‘When she first received her patent, Anderson attempted to sell it to a Canadian manufacturing firm, but the company refused, claiming that the device had no practical value and therefore wasn’t worth any money.’ Anderson never made a dime from his innovation, even though mechanical windshield wipers were standard equipment in passenger automobiles by roughly 1913.
People were dismissive of Anderson’s design, claiming that the movement of the wipers would distract the driver and result in an accident.
What’s the irony?
Anderson Company was created in South Bend, Indiana, by inventor John Anderson when he was 35 years old to manufacture manifolds and ignition timers for Henry Ford’s Model T. During a wet night drive in 1925, according to his biography, he discovered that his wiper blade insert had become damaged and needed to be replaced. He was unable to locate a substitute. As a result, his firm began producing replacement windshield wiper blades and windshield wiper inserts under the ANCO brand. ANCO wipers quickly rose to become one of the most recognizable names in the United States.
Anderson was the name of both the inventor and the company’s chief marketing officer.
TRICO Wiper Blades
Trico, formerly known as the Tri-Continental Corporation, was the first company to commercialize a windshield wiper blade in 1917. Trico is presently one of the world’s largest producers of windshield wiping systems, windshield wiper blades, and windshield wiper refills, with wiper factories on five continents. Trico is a division of Tricon Corporation.

4 Fun History Facts About Windshield Wipers
Because they provide you with a clear view of the road, windshield wipers are your car’s first line of defense, helping you to prevent accidents and stay safe on the road. In the more than a century that they have been in use, they have advanced significantly. Some of the most notable advances in the history of these critical automobile components are listed below.
A Woman Invented Modern Windshield Wipers
As vehicles became increasingly prevalent, it became evident that maintaining a clear windshield was essential for safe driving on the highway. The invention of functional windshield wipers dates back to 1896, and various efforts have been made to date. Today, the general agreement is that Mary Anderson, an American inventor who patented her ‘window washing device’ in 1903, should be given the credit for the creation of a functional windshield wiper. Without this woman’s creation, we would surely have had problems keeping on the road, despite the fact that men predominated in the automobile’s early history.
In the absence of windshield wipers to maintain our vision of the road clean, we would be far more likely to suffer damage to our vehicles that would necessitate the need for a car windshield repair or a truck windshield replacement. Because it would be inappropriate for the wipers to obscure that view on their own, we have intermittent wipers today. Robert Kearns was blind in one eye and had difficulties seeing due to the continual wiping of his eyelids. He developed the intermittent wiper, which stops for a brief period between each stroke, making it much easier to view the road ahead of you.
Windshield Wipers – Automatic Wiping Speed
Citroen, a French automobile manufacturer, was the first to develop windshield wipers that automatically alter the pace at which they intermittently wipe. The wiper blades on the 1970 Citroen SM were capable of adjusting their delay in response to the amount of power being used by the wiper motor. It is possible that when there is heavy rain, the windshield wiper will require more power to clean the windshield, and the circuit will raise the wiping speed.
The Spring-Tension Blade
Three decades ago, Tri-Continental Corporation was credited with inventing the contemporary spring-tension wiper blade for curved glass windshields. The firm, which is now known as Trico, was founded in 1917 and invented this type of wiper blade. Even though the first vehicles had flat windshields, curved windshields required pressure from the blades in order for them to distribute uniformly throughout the curved surface. These blades help to maintain modern windshields clear, preventing accidents that might result in the need for expensive RV windshield replacement or commercial windshield replacement costs.
Mary Anderson patents windshield wiper
The U.S. Patent and Trademark Office has awarded Mary Anderson of Birmingham, Alabama, U.S. Patent No. 743,801 for her ‘window cleaning device for electric cars and other vehicles to remove snow, ice, or sleet from the window.’ Anderson is the first woman to receive a patent for a window cleaning device. When Anderson acquired her patent, she attempted to sell it to a Canadian manufacturing business, but the company refused, claiming that the gadget had no practical utility and hence was not worth any money.
Anderson never made a dime from his innovation, even though mechanical windshield wipers were standard equipment in passenger automobiles by roughly 1913.
However, despite the fact that the trolley’s front window was designed for poor weather visibility—it was divided into sections so that the driver could open it, thereby moving the snow- or rain-covered section out of his line of vision—the multi-pane windshield system performed extremely poorly in practice.
- Anderson began sketching her wiper device on the tram, directly in front of her.
- With a single pull of the lever, the driver dragged the spring-loaded arm over the glass and back again, removing rainfall or snowflakes or other debris.
- In order to appeal to those who lived in areas where it did not rain during the summer, this feature was most likely implemented.
- Her patent expired before she was able to persuade anyone to implement her concept.
- It was an automated wiper system that employed rollers instead of blades.

History of Wiper Blades Part 1
The creation of the wiper As with Newton’s fall, an apple was the spark for the creation of wiper blades. However, unlike Newton’s narrative about the apple, this one is based on actual events. The year is 1902, and the location is New York City. Visiting from Alabama, Mary Anderson discovers that the weather makes spotting sights from a street vehicle practically impossible due to the snow and ice. The combination of Mary’s inquisitiveness and the weather would eventually lead to the creation of the windshield wiper blade – even though she didn’t end up making any money off of her work on the project.
Old Cars Had No Need For Wiper Blades
Is air conditioning a feature of your present automobile? Don’t make fun of me! Many people have experienced a time in their lives when central air conditioning was not a typical choice. However, it is now. Radios, automated windows and door locks, and an automatic gearbox are all examples of convenience features. Automobiles, like all other things, have evolved over the course of time. Moreover, when Mary was struck with inspiration in the early 1900s, the majority of automobiles did not even include windshields!
The story of Mary Anderson and the development of wiper blades is a classic illustration of how necessity can lead to innovation. During the winter of 1902, Mary was traveling through New York City on a street car system. Her observations regarding the rain and sleet included the following: Rain made it difficult to see: passengers couldn’t see out of the windows. However, the driver’s vision was impaired, which was more significant. In addition to decreasing economy and comfort, drivers were forced to stop and clean their windshields, which reduced visibility.
Mary, a wealthy entrepreneur, instantly began to think about what she should do.
Daydreams and Doodles
While pondering and drawing ideas for ways to clear rain, sleet, and anything else off the windshield without having to venture out into the cold, wet weather, Mary came up with a solution. As it turns out, her concept isn’t all that far from our current state of affairs: she saw a lever on the interior of the automobile that would run a rubber blade down the glass, cleaning it. Aside from the addition of automation, the current model hasn’t altered much. In November of 1903, Mary applied for and acquired a patent for her window-cleaning system, which she had designed and sketched previously.

Using windshield wipers, you can keep the windshield of your automobile clean so that you have a clear view of the road in front of you.
When driving a passenger automobile, the normal wipe angle is around 67 degrees. The blades range in length from 12 to 30 inches (30 to 76 centimeters), with lengths rising in 2-inch (5-centimeter) intervals.
The introduction of the vehicle marked the beginning of the history of the windshield wiper. The majority of public transit vehicles did not have windshield wipers. In those days, horse-drawn carriages and trucks travelled at a sluggish pace, and hence no glass was required to shield the driver or passengers or to function as a windbreak. Brushes were used as the earliest windshield wipers. 1903 saw the invention of a system of rotating two brushes up and down on a vertical plate glass windshield, developed by inventor J.
- Anderson received a patent for her mechanical windshield wiper design in 1905, and it became standard equipment by 1913, according to Anderson.
- Because there was no other source of power, the driver had to operate the lever with only one hand.
- In 1905, rubber strips took the role of brushes as the cleaning equipment on windshield wipers.
- Using an electric motor to drive a single wiper equipped with a long rubber blade in a back and forth motion was the answer.
- After the invention of the electric starter in 1912, wipers were one of the first electrical devices to be installed in vehicles.
- Due to the increasing complexity of electrical systems, they were relocated to the base of the windshield.
- Bob Kearns designed the intermittent wiper in 1962, with variable intervals and speeds that could be adjusted by the driver.
- In the 1980s, wipers were integrated into headlights, necessitating the establishment of links between the lighting and wiper systems.
Microsensors were installed in windshields in the 1990s to detect rain on the windshield, activate the wipers, and change the speed and intermittent usage of the wipers according to the quantity of rain.
Each component is procured by the producer from businesses that specialize in the fabrication of aluminum and steel components, rubber blades, plastic bushings for the linkages, and motors. Generally speaking, windshield wipers and windshield wiper systems (which include motors) are two distinct assemblies; some manufacturers create both, while others just make wipers. Galvanized steel is used to construct the connecting and driving links, as well as the pivots that move the wipers. In order to preserve steel against corrosion, galvanization is the process of putting a zinc coating to the steel.
- The wiper suspension and claws are made of galvanized steel, as is the rest of the vehicle.
- Steel is also used in the little parts of wipers, such as washers, screws, nuts, springs, and brackets, as well as in the larger portions of wipers.
- Natural rubber or synthetic substances are used to construct the blades.
- Rubber washers in the pivots and plastic bushings that fill the holes for connecting sections of the linkage are two more materials that are used in the manufacture of windshield wiper components.
- If the wiper maker also manufactures wiper systems, the motors are obtained from subcontractors who supply the wiper manufacturer.
- Wiring harnesses that are particular to operating the wipers are provided with each housing, and connections for the electrical wires that are part of the vehicle are made in each housing.
When it comes to clearing water from a windshield, windshield wipers are developed and manufactured specifically for this purpose. Most automobiles have two wipers on the windshield, and some also have one on the back window and one on each of the four front headlights. The rubber wiper blade, the wiper arm that holds the blade, a spring linkage, and elements of the wiper pivots are the wiper pieces that are visible from the exterior of the automobile. The wiper itself is made up of up to six pieces known as pressure points or claws, which are little arms that run below the wiper.
- This is referred to as a balancing beam with a suspension system, in which the wiper serves as the beam and the claws serve as the suspension system’s suspension components.
- More claws, on the other hand, tend to effectively disperse pressure and are better suited to big or highly curved windshields.
- The replacement holes allow you to easily swap out the rubber blade with a new one when necessary.
- Typically, the normal two windshield wipers are operated as a single-motor tandem system, with one wiper on the driver’s side and another around the middle of the windshield that travels across the passenger’s field of vision.
- Both ends of a long rod called the connecting link have a wiper and a pivot set on brackets.
- Close to the wiper motor, the connecting link is connected to another long rod known as the driving link via a nut.
- A linkage system composed of a cam (another short rod) and pivot, a gear output shaft, and a worm gear is located between the motor and the drive link, and it is responsible for controlling the amount of force provided to the drive arm.
The gear enables a tiny motor to provide enough force to move the blades over the glass with sufficient precision.
If a single motor drives each wiper, additional linkages are required to move the two wipers together in a so-called unitized motor system, which is a type of hybrid vehicle.
It is the most frequent configuration because the blades provide overlapping cleared regions on the windshield, with the largest overlap occurring in front of the driver.
It is also possible to employ a single wiper that swings in an arc from the center of the windshield.
Each of the two wipers in the tandem and opposing operating schemes, as well as the one wiper in the single-wiper operating scheme, creates an arc with a single radius, and as a result, they are referred to as radial arm wipers (or radial arm wipers in certain circles).
The electric motor, worm gear, gear shaft, cam, drive link, and pivots are all integrated into the underside of the dash for convenience.
When not in use, wipers known as depressed wipers can be found resting beneath the molding of the vehicle.
The on/off switch for the windshield wipers is often located on the steering column in the passenger compartment.
As soon as the wipers are switched off, the circuit interrupts the flow of electricity to the wiper motor. Intermittent functioning of the wipers is effectively a series of short on-and-off times for the wiper motor, which is likewise controlled by the circuit.
The Manufacturing Process
- Wiper manufacturers have substantial inventories of materials supplied by subcontractors. As soon as the materials are received, the receiving inspectors verify that the kinds and quantities of components are right, construct an inventory of the parts, and store the items in a secure location. The worker starts by fitting together the pivot shafts for each wiper on the wiper assembly. With a series of bolts and spacers, the pivot shaft holds the wiper arm firmly while enabling it to pivot and sweep the wiper angle specified by the manufacturer in the design specification. This assembly consists of the pivot shaft itself and (from the end of the shaft at the little connecting link to the tip of the shaft) a rubber washer, a metal washer, and various nuts and washers such as a nut cap, a knurled driver, a washer, and an acorn nut, among other things. The knurled driver is a sort of nut that has grooves on the sides that are designed to grasp any form of connection. The wiper arm will rest on the knurled driver, which will prevent it from slipping out of position on the shaft, and the arm will be held in place on the shaft by a washer and an acorn nut. The pivot shaft is next connected to the little connecting link by use of a washer and a spring clip, and the process is repeated. When the shaft is attached to the link, a pin on the pivot shaft can be inserted into one of three pin positions, depending on the design of the pivot and link. For a single-arm wiper scheme, a U-shaped, galvanized steel bracket is fixed to the small connecting link on the only pivot shaft with two shaft screws
- For a two-arm wiper scheme, a U-shaped, galvanized steel bracket is fixed to the small connecting link on the only pivot shaft with two shaft screws. The other end of the bracket will be connected to the drive link at a later time. To unite the tiny connecting link for the wiper on passenger’s side of vehicle to the end of the longer connecting link with shaft screws in a scheme with two wipers, the small connecting link is linked with a bracket to the end of the longer connecting link with shaft screws. In a similar manner, a bracket is attached to the tiny connecting link for the driver’s side wiper and the other end of the longer connecting link is joined to the smaller connecting link. Later on, this end will be connected to the drive link, which will then be connected to the motor in the following phase. The motor, along with the worm gear reduction and other components, is a stock item given by a vendor, and the wiper system maker makes no modifications to this component. As well as ensuring that the wiper sweeps appropriately, the drive link must be precisely connected to the cam (drive arm) at the other end of the gear shaft to ensure that it can be parked in the proper place beneath the automobile molding as well. It is necessary to use another bracket, known as the mirror bracket, in order to secure the connection between the cam and drive link. The motor, cam, mirror bracket, and drive link are all placed inside a die set in order to set the angle between the drive link and the cam and motor. link and motor The die set is an outline-like design made of steel with sections that are pre-cut to fit the four elements of the die set together. When it comes to mounting the drive link to the motor, wiper system manufacturers have a collection of die sets with a variety of angles for use. A series of screws are used to attach the bracket to the drive link. The bracket is then mounted to the cam
- Once the angle has been determined, the cam is verified to ensure that it is in proper alignment with the driving shaft. In order to connect the cam and drive shaft, spacer washers are used between the two components, and a pair of motor nuts and screws are used to secure the two together. When using a single-wiper scheme, the bracket with the single tiny link and pivot is fastened to the driving link and secured with a bolt. The bracket at the end of the long connecting link, which also supports the driver’s side pivot and tiny connecting link, is connected to the drive link in a scheme with two wipers. Linkages constructed of springs are added to each pivot shaft to connect it to the drive link during the last stages of the windshield wiper system’s assembly, which is the final phase. The wiper arms and blades are attached to the pivots by means of ball joints. It is also necessary to set the wipers in their respective park positions, as well as to shift the starter on the motor into the park position. If a consumer purchases windshield wiper systems, it is possible that accessories may be supplied. The most popular accessory kit consists of a set of washers, together with water bottles, tubing, and controls for the dashboard. When you purchase the motor, it comes with a wire harness that includes the washer controls as well as all of the other electrical connections for the wipers. The completed windshield wipers are subjected to a final quality control check, which is explained in further detail below, before being moved to the packing section. In accordance with the products bought, each set of wipers, a motor system, and accessories is packaged with information on how to operate, maintain, and return the product
If a consumer orders many goods, the different boxes are grouped together and placed in shipping cartons to save on shipping costs.
Although the workers are constantly inspecting the parts as they work, their only specific quality control activity is to check the operation of the motors, which they do by turning them on to ensure that they start and by listening to the sounds they make as indicators of their performance during assembly. The final inspection is carried out after the assemblies have been completed but before the wipers and systems are packed for shipment. The production director or final quality control inspectors examine the overall appearance of the assemblies, validate that the wipers have been sized and slanted appropriately for their sweep, and verify that the assemblies are in the park position.
The director or inspectors also check to make sure that the necessary accessories are ready to be packed with the assemblies before they are sent to the factory.
Small quantities of steel and aluminum scraps from trims, rejected or broken components, and other sources are gathered in bins and sold to salvage merchants, who in turn sell them to metal producers, who in turn melt the scrap down and reuse it as raw material. The packaging from which the components are received is also recovered and recycled.
Automobiles and other motor vehicles, technological advances, and market demand are all contributing to the evolution of windshield wipers and wiper systems, which began in the year 2002. Wiper blades may be as long as 30 inches (76 cm), resulting in greater resistance as they clear the windscreen. Windshield night-vision screens are also being developed, and they will likewise increase resistance while also altering the proportions required for windshield wipers. Nonstick coatings on the squeegee edges of the blades, which prevent oil and wax from adhering to them and aging them, are among the improvements being made to blades.
In addition, the voltage of motor systems is being raised in order to power longer wipers and additional accessories.
Inventors anticipate that the capabilities of the rain-detecting sensors that were available in the late 1990s would be expanded so that the wipers may be activated to clear filthy windshields even when there is no rain.
