A '''windscreen wiper''' ([[Commonwealth English]]) or '''windshield wiper''' ([[American English]]) is a device used to remove rain, snow, ice, washer fluid, water, or other debris from a [[windscreen|vehicle's front window]]. Almost all [[motor vehicle]]s, including [[car]]s, [[truck]]s, [[bus]]es, [[train]] [[locomotive]]s, and [[watercraft]] with a [[Cabin (ship)|cabin]]—and some [[aircraft]]—are equipped with one or more such wipers, which are usually a legal requirement.

In this common design, the [[force]] from the arm is distributed evenly with a series of linkages known as a [[Whippletree (mechanism)|''whippletree'']].]] [[File:2008-04-24 Windshield wiper parts.jpg|thumb|A common windscreen wiper arm and blade]] [[File:Jakarta MRT train windscreen wiper.webm|thumb|A train windscreen wiper in operation (MRT Jakarta)]] A '''windscreen wiper''' ([[Commonwealth English]]) or '''windshield wiper''' ([[American English]]) is a device used to remove rain, snow, ice, washer fluid, water, or other debris from a [[windscreen|vehicle's front window]]. Almost all [[motor vehicle]]s, including [[car]]s, [[truck]]s, [[bus]]es, [[train]] [[locomotive]]s, and [[watercraft]] with a [[Cabin (ship)|cabin]]—and some [[aircraft]]—are equipped with one or more such wipers, which are usually a legal requirement. A wiper generally consists of a metal arm; one end [[Lever|pivots]], and the other end has a long rubber blade attached to it. The arm is powered by a [[motor]], often an [[electric motor]], although [[pneumatic power]] is also used for some vehicles. The blade is swung back and forth over the glass, pushing water, other [[precipitation]], or any other impediments to visibility from its surface. The speed is usually adjustable on vehicles made after 1969, with several continuous rates and often one or more ''intermittent'' settings. Most personal automobiles use two synchronized ''radial''-type arms, while many commercial vehicles use one or more ''[[pantograph]]'' arms. On some vehicles, a '''windscreen washer''' system is also used to improve and expand the function of the wiper(s) to dry or icy conditions. This system sprays water, or an [[antifreeze]] [[Windshield washer fluid|window washer fluid]], at the windscreen using several well-positioned [[nozzle]]s. This system helps remove dirt or dust from the windscreen when used in concert with the wiper blades. When antifreeze washer fluid is used, it can help the wipers remove snow or ice. For these types of winter conditions, some vehicles have additional [[Heating, ventilation, and air conditioning|heaters]] aimed at the windows, embedded [[Heating element|heating wire(s)]] in the glass, or embedded [[Heating element|heating wire(s)]] in the wiper blade; these [[Defogger|defroster systems]] can melt ice or help to keep snow and ice from building up on the windscreen. Less frequently, miniature wipers are installed on [[headlight]]s to ensure they function optimally. == History == === Early versions === [[File:Windshield Cleaner - from Patent.jpg|thumb|Patent illustration of 'window cleaner' by GEORGE J. CAPEWELL, OF HARTFORD, CONNECTICUT]] One of the earliest recorded patents for the windscreen wiper is by [[George Capewell|George J. Capewell]] of Hartford Connecticut, which was filed on August 6, 1896.<ref>{{cite web|url=https://patents.google.com/patent/US609787A/en|title=WINDOW CLEAN.|website=google.com|access-date=7 March 2019}}</ref> His invention was for "windows of slow-moving craft; but it is more particularly adapted and intended for windows of rapidly-moving vehicles, such as high-speed locomotives and cars, with which it is necessary that the observer or driver should have a clear view of the path or track." Similar to current automotive wiper designs, his invention involves "usually two of these wipers, and they can be secured to the frame below the front board of the vehicle or behind the housing surrounding the window in position to be out of sight and in such manner that one will scrape off the heaviest part of the substance collected upon the glass." His patent illustration shows a circular window, although the patent notes "it is not essential that the glass be circular in form." Other early designs for the windscreen wiper are credited to Polish concert [[pianist]] [[Józef Hofmann]],<ref>{{cite book |vauthors=Day T |title=A Century of Recorded Music: Listening to Musical History |date=2000 |publisher=Yale University Press |isbn=978-0-300-09401-5 |page=11 |language=en}}</ref> and to Mills Munitions, [[Birmingham]], who also claimed to have been the first to patent windscreen wipers in England. At least three inventors patented windscreen cleaning devices at around the same time in 1903; [[Mary Anderson (inventor)|Mary Anderson]], Robert Douglass, and John Apjohn. In April 1911, a patent for windscreen wipers was registered by Sloan & Lloyd Barnes, patent agents of Liverpool, England, for [[Gladstone Adams]] of [[Whitley Bay]]. [[File:Anderson Window Cleaning Device 1903.png|thumb|upright|Anderson's 1903 window cleaner design]] American inventor [[Mary Anderson (inventor)|Mary Anderson]] is popularly credited with devising the first operational windscreen wiper in 1903.<ref name="AmHer">{{cite web|title=The Windshield Wiper|publisher=American Heritage|url=http://www.americanheritage.com/events/articles/web/20070709-windshield-wiper-robert-kearns.shtml|access-date=2010-12-23|archive-date=2007-09-11|archive-url=https://web.archive.org/web/20070911215242/http://www.americanheritage.com/events/articles/web/20070709-windshield-wiper-robert-kearns.shtml|url-status=dead}}</ref><ref>{{cite web|title=Windshield Wipers |publisher=Massachusetts Institute of Technology |url=https://lemelson.mit.edu/resources/mary-anderson}}</ref> In Anderson's patent, she called her invention a "window cleaning device" for electric cars and other vehicles.

The new vacuum-powered system quickly became standard equipment on automobiles, and the vacuum principle was in use until about 1960. In the late 1950s, a feature common on modern vehicles first appeared, operating the wipers automatically for two or three passes when the windscreen washer button was pressed, making it unnecessary to manually turn the wipers on as well. Today, an electronic timer is used, but originally a small vacuum cylinder mechanically linked to a switch provided the delay as the vacuum leaked off. === Intermittent wipers === The [[inventor]] of intermittent wipers (non-continuous, now including variable-rate wipers) might have been Raymond Anderson, who, in 1923, proposed an [[electro-mechanical]] design. (US Patent 1,588,399). In 1958, Oishei et al. filed a [[patent application]] describing not only electro-mechanical, but also [[Thermal engineering|thermal]] and [[Hydraulics|hydraulic]] designs. (US Patent 2,987,747). Then, in 1961, John Amos, an engineer for the UK [[automotive engineering]] company [[Lucas Industries]], filed the first patent application in the UK for a [[Solid-state electronics|solid-state electronic]] design. (US patent 3,262,042). In 1963, another form of intermittent wiper was invented by [[Robert Kearns]], an [[engineering professor]] at [[Wayne State University]] in [[Detroit]], Michigan.<ref name="AmHer" /> (United States Patent 3,351,836 – 1964 filing date). Kearns's design was intended to mimic the function of the [[human eye]], which [[Blinking|blinks]] only once every few seconds. In 1963, Kearns built his first intermittent wiper system using off-the-shelf electronic components. The interval between wipes was determined by the [[RC time constant|rate of current flow into a capacitor]]; when the charge in the [[capacitor]] reached a certain [[voltage]], the capacitor would be discharged, activating one cycle of the wiper motor, and then repeating the process. Kearns showed his wiper design to the [[Ford Motor Company]] and proposed that they manufacture the design. Ford [[Business executive|executives]] rejected Kearns' proposal at the time, but later offered a similar design as an option on the company's [[Ford Mercury|Mercury line]], beginning with the 1969 models.<ref name="AmHer" /> Kearns sued Ford in a multi-year [[patent dispute]] that Kearns eventually won in court,<ref>{{cite news |title=Accomplished, Frustrated Inventor Dies|first=Matt|last=Schudel|url=https://www.washingtonpost.com/wp-dyn/articles/A54564-2005Feb25.html|newspaper=[[Washington Post]]|date=26 February 2005|access-date=12 December 2011}}</ref> inspiring the [[2008 film|2008 feature film]] ''[[Flash of Genius (film)|Flash of Genius]]'' based on a 1993 [[New Yorker Magazine|New Yorker]] article that covered the legal battle. In March 1970, French automotive manufacturer [[Citroën]] introduced more advanced [[rain]]-sensitive intermittent windscreen wipers on its [[Citroën SM|SM model]]. When the intermittent function was selected, the wiper would make one sweep. If the windscreen was relatively dry, the wiper motor drew high [[Electric current|current]], which would set the control [[Electric Circuit|circuit]] timer to a long delay for the next wipe. If the motor drew little current, it indicated that the glass was still wet, and would set the timer to minimize the delay. == Power == [[File:Nahverkehrsmunseum-Triebwagen-431-DSC 6417.jpg|thumb|[[Pneumatic motor]] drive on a railroad locomotive windscreen wiper. The lever on the motor operates a valve to supply pressurized air.]] Wipers may be powered by a variety of means, although most in use today are powered by an [[electric motor]] through a series of mechanical components, typically two [[4-bar linkage]]s in series or [[Parallel circuits|parallel]]. Vehicles with air-operated brakes sometimes use [[pneumatic]] wipers, powered by tapping a small amount of pressurized air from the brake system to a small air operated motor mounted on or just above the windscreen. These wipers are activated by opening a valve which allows pressurized air to enter the motor. Early wipers were often driven by a [[vacuum motor]] powered by [[manifold vacuum]]. This had the drawback that manifold vacuum varies depending on [[throttle]] position, and is almost non-existent under wide-open throttle, when the wipers would slow down or even stop. That problem was overcome somewhat by using a combined fuel/vacuum booster pump. Some cars, mostly from the 1960s and 1970s, had variable-speed, hydraulically-driven wipers, most notably the '61–'69 [[Lincoln Continental]],<ref>{{cite web|url=https://autouniversum.wordpress.com/2014/06/25/10186/|title=The Cars of James Bond: Lincoln Continental|date=25 June 2014|website=wordpress.com|access-date=5 April 2018}}</ref> '69–'71 [[Lincoln Continental Mark III]] (but not all '70 models),<ref>{{cite web|url=http://automotivemileposts.com/contentsmark3.html|title=Automotive Mileposts, 1969-1971 Lincoln Continental Mark III|access-date=1 June 2020}}</ref> and '63–'71 [[Ford Thunderbird]].<ref>{{cite web|url=http://automotivemileposts.com/contentstbird.html|title=Automotive Mileposts, 1955-1979 Ford Thunderbird|access-date=1 June 2020|archive-date=21 July 2011|archive-url=https://web.archive.org/web/20110721174124/http://automotivemileposts.com/contentstbird.html|url-status=dead}}</ref> These were powered by the same hydraulic pump also used for the power steering mechanism. On the earlier [[Citroën 2CV]], the windscreen wipers were powered by a purely mechanical system, a cable connected to the transmission; to reduce cost, this cable also powered the speedometer. The wipers' speed was therefore variable with car speed. When the car was stationary, the wipers were not powered, but a handle under the speedometer allowed the driver to power them by hand.{{citation needed|date=June 2011}} == Shape == [[File:Patent US2596063A Illustration.png|thumb|Illustration showing the construction of multi-branched windshield wiper blade holder]] Most early wipers used a rubber blade attached to a flat metal base. But as aerodynamic and styling concerns introduced curved windshields, these proved insufficient. In 1945, John W.

(Fig. 2)]] [[File:Transperth Volgren CR225L bodied Mercedes-Benz O405NH CNG.jpg|thumb|Pantograph windscreen wipers (Fig. 6) used on [[Mercedes-Benz O405|Mercedes-Benz O 405 NH]]]] [[File:Daf_A.Reijerse_&_Zn._Wassenaar.jpg|thumb|right|Triple windshield wipers (Fig.7) used on a DAF XF truck]] Most wipers are of the pivot (or radial) type: they are attached to a single arm, which in turn is attached to the motor. These are commonly found on many cars, trucks, trains, boats, airplanes, etc. Modern windscreen wipers usually move in parallel (Fig. 1, below). However, various [[Mercedes-Benz]] models and other cars such as the [[Volkswagen Sharan]] employ wipers configured to move in opposite directions (Fig. 2), which is mechanically more complex but can avoid leaving a large unwiped corner of the windscreen in front of the front-seat passenger. A cost benefit to the auto-maker occurs when wipers configured to move in opposite directions do not need to be repositioned for cars exported to [[right hand drive]] countries such as the UK and Japan. Another wiper design (Fig. 6) is pantograph-based, used on many commercial vehicles, especially buses with large windscreens. Pantograph wipers feature two arms for each blade, with the blade assembly itself supported on a horizontal bar connecting the two arms. One of the arms is attached to the motor, while the other is on an idle pivot.{{Citation needed|date=October 2010}} The pantograph mechanism, while being more complex, allows the blade to cover more of the windscreen on each wipe. However, it also usually requires the wiper to be "parked" in the middle of the windscreen, where it may partially obstruct the driver's view when not in use. A few models of automobile sometimes employ a pantograph arm on the driver's side and a normal arm for the passenger. The Triumph Stag, Lexus and several US makes employ this method to cover more glass area where the windscreen is quite wide but also very shallow. The reduced height of the windscreen would need the use of short wiper arms which would not have the reach to the edge of the windscreen. A simple single-blade setup with a center pivot (Fig. 4) is commonly used on rear windscreens, as well as on the front of some cars. [[Mercedes-Benz]] pioneered a system (Fig. 5) called the "Monoblade", based on [[cantilever]]s, in which a single arm extends outward to reach the top corners of the windscreen, and pulls in at the ends and middle of the stroke, sweeping out a somewhat M-shaped path. This way, a single blade is able to cover more of the windscreen, displacing any residual streaks away from the centre of the windscreen. Some larger cars in the late '70s and early '80s, especially [[Right- and left-hand traffic#Driver seating position|LH driver]] American cars{{Citation needed|date=October 2010}}, had a pantograph wiper on the driver's side, with a conventional pivot on the passenger side. Asymmetric wiper arrangements are usually configured to clear more windscreen area on the driver's side, and so are mostly mirrored for left and right-hand-drive vehicles (for example, Fig. 1 vs. Fig 10).

Rear-window wipers are typically found on [[hatchback]]s, [[station wagons]] / estates, [[sport utility vehicle]]s, [[minivan]]s, and other vehicles with more vertically-oriented rear windows that tend to accumulate dust. First offered in the 1940s, they achieved widespread popularity in the 1970s after their introduction on the Porsche 911 in 1966 and the Volvo 145 in 1969.<ref>{{cite web|url=https://autouniversum.wordpress.com/2015/04/30/the-rear-wiper-a-vital-strand-of-porsche-dna/|title=The Rear Wiper: A Vital Strand of Porsche DNA|date=30 April 2015|website=wordpress.com|access-date=5 April 2018}}</ref> {{clear right}} === Headlight wipers === In the 1960s, as interest in auto safety grew, engineers began researching various headlamp cleaning systems. In late 1968, Chevrolet introduced high pressure fluid headlamp washers on a variety of their 1969 models. In 1970, [[Saab Automobile]] introduced [[headlight]] wipers across their product range. These operated on a horizontal reciprocating mechanism, with a single motor. They were later superseded by a radial spindle action wiper mechanism, with individual motors on each headlamp. In 1972, headlamp cleaning systems became mandatory in Sweden. Headlamp wipers have all but disappeared today with most modern designs relying solely on pressurized fluid spray to clean the headlights. This reduces manufacturing cost, minimizes aerodynamic drag, and complies with EU regulations limiting headlamp wiper use to glass-lensed units only (the majority of lenses today are made of plastic.) == Other features == [[File:Wischwaschanlageinaktion.jpg|thumb|upright|Windscreen washer in operation]] === Windscreen washer === {{See also|Windscreen washer fluid}} Most windscreen wipers operate together with a windscreen washer; a [[pump]] that supplies a mixture of water, [[ethanol|alcohol]], and [[detergent]] (a blend called [[windscreen washer fluid]]) from a tank to the windscreen. The fluid is dispensed through small [[nozzle]]s mounted on the [[Hood (vehicle)|hood]]. Conventional nozzles are usually used, but some designs use a [[fluidic]] [[oscillator]] to disperse the fluid more effectively. In warmer climates, water may also work, but it can freeze in colder climates, damaging the pump. Although automobile [[antifreeze]] is chemically similar to windscreen wiper fluid, it should not be used because it can damage paint. The earliest documented idea for having a windscreen wiper unit hooked up to a windscreen washer fluid reservoir was in 1931, Richland Auto Parts Co, Mansfield, Ohio.<ref>[https://books.google.com/books?id=u-IDAAAAMBAJ&dq=Popular+Mechanics+1931+curtiss&pg=PA248 Windshield Freed Of Snow With Alcohol Wiper", February 1931, Popular Mechanics] article bottom half of page</ref><ref>{{cite news |title=car detailing services |url=https://www.bowtiedetailing.com/}}</ref> Uruguayan racecar driver and mechanic [[Héctor Suppici Sedes]] developed a windscreen washer in the late 1930s.<ref>[http://archivo.lavoz.com.ar/2001/0101/nota8051_1.htm Supicci Sedes, un espíritu creador] - La Voz del Interior, 1 January 2001</ref> Since 2012, nozzles are replaced on some cars (Tesla, Volvo XC60 2018-2021, Citroen C4 Cactus) by a system called AquaBlade, developed by the company Valeo. This system supplies the washing liquid directly from the spoiler element of the wiper blade. This system suppresses visual disturbances during driving and so reduces the reaction time of the driver in case of incident.<ref>ATZ, Automobiltechnische Zeitschrift, June 2015</ref> === Hidden wipers === Some larger cars are equipped with '''hidden wipers''' (or '''depressed-park wipers'''). When wipers are switched off in standard non-hidden designs, a "parking" mechanism or circuit moves the wipers to the lower extreme of the wiped area near the bottom of the windscreen, but still in sight. For designs that hide the wipers, the windscreen extends below the rear edge of the bonnet. The wipers park themselves below the wiping range at the bottom of the windscreen, but out of sight. Late model vehicles that hide wiper blades under the windscreen need to be placed in a service position in order to lift the wiper blade from the windscreen using the wiper service position. === Rain-sensing wipers === Some vehicles are now available with automatic or driver-programmable windscreen wipers that detect the presence and amount of rain using a [[rain sensor]]. The sensor automatically adjusts the speed and frequency of the blades according to the amount of rain detected. These controls usually have a manual override. Rain-sensing windscreen wipers appeared on various models in the late 20th century, one of the first being the [[Citroën SM]]. {{As of|2006|alt=As of early 2006}}, rain-sensing wipers are optional or standard on all [[Cadillac]]s and most [[Volkswagen]]s, and are available on many other mainstream manufacturers. The rain-sensing wipers system currently employed by most car manufacturers today was originally invented and patented in 1978 by Australian, Raymond J. Noack, see U.S. Patents 4,355,271 and 5,796,106. The original system automatically operated the wipers, lights and windscreen washers. ==Bladeless alternatives== [[File:Rotating windshield wiper.jpg|thumb|[[Clear view screen]] provides a window of visibility, even in rough seas.]] A common alternative design used on ships, called a [[clear view screen]], avoids the use of rubber wiper blades. A round portion of the windscreen has two layers, the outer one of which is spun at high speed to shed water. High speed aircraft may use [[bleed air]] which uses compressed air from the turbine engine to remove water, rather than mechanical wipers, to save weight and drag.{{citation needed|date=September 2014}} Effectiveness of this method also depends on [[hydrophobic|water-repellent]] glass treatments similar to [[Rain-X]]. == Legislation == Many jurisdictions have legal requirements that vehicles be equipped with windscreen wipers. Windscreen wipers may be a required safety item in auto [[safety inspection]]s.

In this common design, the [[force]] from the arm is distributed evenly with a series of linkages known as a [[Whippletree (mechanism)|''whippletree'']].]] [[File:2008-04-24 Windshield wiper parts.jpg|thumb|A common windscreen wiper arm and blade]] [[File:Jakarta MRT train windscreen wiper.webm|thumb|A train windscreen wiper in operation (MRT Ronaldo suiiiiiii A '''windscreen wiper''' ([[Commonwealth English]]) or '''windshield wiper''' ([[American English]]) is a device used to remove rain, snow, ice, washer fluid, water, or other debris from a [[windscreen|vehicle's front window]]. Almost all [[motor vehicle]]s, including [[car]]s, [[truck]]s, [[bus]]es, [[train]] [[locomotive]]s, and [[watercraft]] with a [[Cabin (ship)|cabin]]—and some [[aircraft]]—are equipped with one or more such wipers, which are usually a legal requirement. A wiper generally consists of a metal arm; one end [[Lever|pivots]], and the other end has a long rubber blade attached to it. The arm is powered by a [[motor]], often an [[electric motor]], although [[pneumatic power]] is also used for some vehicles. The blade is swung back and forth over the glass, pushing water, other [[precipitation]], or any other impediments to visibility from its surface. The speed is usually adjustable on vehicles made after 1969, with several continuous rates and often one or more ''intermittent'' settings. Most personal automobiles use two synchronized ''radial''-type arms, while many commercial vehicles use one or more ''[[pantograph]]'' arms. On some vehicles, a '''windscreen washer''' system is also used to improve and expand the function of the wiper(s) to dry or icy conditions. This system sprays water, or an [[antifreeze]] [[Windshield washer fluid|window washer fluid]], at the windscreen using several well-positioned [[nozzle]]s. This system helps remove dirt or dust from the windscreen when used in concert with the wiper blades. When antifreeze washer fluid is used, it can help the wipers remove snow or ice. For these types of winter conditions, some vehicles have additional [[Heating, ventilation, and air conditioning|heaters]] aimed at the windows, embedded [[Heating element|heating wire(s)]] in the glass, or embedded [[Heating element|heating wire(s)]] in the wiper blade; these [[Defogger|defroster systems]] can melt ice or help to keep snow and ice from building up on the windscreen. Less frequently, miniature wipers are installed on [[headlight]]s to ensure they function optimally. == History == === Early versions === [[File:Windshield Cleaner - from Patent.jpg|thumb|Patent illustration of 'window cleaner' by GEORGE J. CAPEWELL, OF HARTFORD, CONNECTICUT]] One of the earliest recorded patents for the windscreen wiper is by [[George Capewell|George J. Capewell]] of Hartford Connecticut, which was filed on August 6, 1896.<ref>{{cite web|url=https://patents.google.com/patent/US609787A/en|title=WINDOW CLEAN.|website=google.com|access-date=7 March 2019}}</ref> His invention was for "windows of slow-moving craft; but it is more particularly adapted and intended for windows of rapidly-moving vehicles, such as high-speed locomotives and cars, with which it is necessary that the observer or driver should have a clear view of the path or track." Similar to current automotive wiper designs, his invention involves "usually two of these wipers, and they can be secured to the frame below the front board of the vehicle or behind the housing surrounding the window in position to be out of sight and in such manner that one will scrape off the heaviest part of the substance collected upon the glass." His patent illustration shows a circular window, although the patent notes "it is not essential that the glass be circular in form." Other early designs for the windscreen wiper are credited to Polish concert [[pianist]] [[Józef Hofmann]],<ref>{{cite book |vauthors=Day T |title=A Century of Recorded Music: Listening to Musical History |date=2000 |publisher=Yale University Press |isbn=978-0-300-09401-5 |page=11 |language=en}}</ref> and to Mills Munitions, [[Birmingham]], who also claimed to have been the first to patent windscreen wipers in England. At least three inventors patented windscreen cleaning devices at around the same time in 1903; [[Mary Anderson (inventor)|Mary Anderson]], Robert Douglass, and John Apjohn. In April 1911, a patent for windscreen wipers was registered by Sloan & Lloyd Barnes, patent agents of Liverpool, England, for [[Gladstone Adams]] of [[Whitley Bay]]. [[File:Anderson Window Cleaning Device 1903.png|thumb|upright|Anderson's 1903 window cleaner design]] American inventor [[Mary Anderson (inventor)|Mary Anderson]] is popularly credited with devising the first operational windscreen wiper in 1903.<ref name="AmHer">{{cite web|title=The Windshield Wiper|publisher=American Heritage|url=http://www.americanheritage.com/events/articles/web/20070709-windshield-wiper-robert-kearns.shtml|access-date=2010-12-23|archive-date=2007-09-11|archive-url=https://web.archive.org/web/20070911215242/http://www.americanheritage.com/events/articles/web/20070709-windshield-wiper-robert-kearns.shtml|url-status=dead}}</ref><ref>{{cite web|title=Windshield Wipers |publisher=Massachusetts Institute of Technology |url=https://lemelson.mit.edu/resources/mary-anderson}}</ref> In Anderson's patent, she called her invention a "window cleaning device" for electric cars and other vehicles.

The new vacuum-powered system quickly became standard equipment on automobiles, and the vacuum principle was in use until about 1960. In the late 1950s, a feature common on modern vehicles first appeared, operating the wipers automatically for two or three passes when the windscreen washer button was pressed, making it unnecessary to manually turn the wipers on as well. Today, an electronic timer is used, but originally a small vacuum cylinder mechanically linked to a switch provided the delay as the vacuum leaked off. === Intermittent wipers === The [[inventor]] of intermittent wipers (non-continuous, now including variable-rate wipers) might have been Raymond Anderson, who, in 1923, proposed an [[electro-mechanical]] design. (US Patent 1,588,399). In 1958, Oishei et al. filed a [[patent application]] describing not only electro-mechanical, but also [[Thermal engineering|thermal]] and [[Hydraulics|hydraulic]] designs. (US Patent 2,987,747). Then, in 1961, John Amos, an engineer for the UK [[automotive engineering]] company [[Lucas Industries]], filed the first patent application in the UK for a [[Solid-state electronics|solid-state electronic]] design. (US patent 3,262,042). In 1963, another form of intermittent wiper was invented by [[Robert Kearns]], an [[engineering professor]] at [[Wayne State University]] in [[Detroit]], Michigan.<ref name="AmHer" /> (United States Patent 3,351,836 – 1964 filing date). Kearns's design was intended to mimic the function of the [[human eye]], which [[Blinking|blinks]] only once every few seconds. In 1963, Kearns built his first intermittent wiper system using off-the-shelf electronic components. The interval between wipes was determined by the [[RC time constant|rate of current flow into a capacitor]]; when the charge in the [[capacitor]] reached a certain [[voltage]], the capacitor would be discharged, activating one cycle of the wiper motor, and then repeating the process. Kearns showed his wiper design to the [[Ford Motor Company]] and proposed that they manufacture the design. Ford [[Business executive|executives]] rejected Kearns' proposal at the time, but later offered a similar design as an option on the company's [[Ford Mercury|Mercury line]], beginning with the 1969 models.<ref name="AmHer" /> Kearns sued Ford in a multi-year [[patent dispute]] that Kearns eventually won in court,<ref>{{cite news |title=Accomplished, Frustrated Inventor Dies|first=Matt|last=Schudel|url=https://www.washingtonpost.com/wp-dyn/articles/A54564-2005Feb25.html|newspaper=[[Washington Post]]|date=26 February 2005|access-date=12 December 2011}}</ref> inspiring the [[2008 film|2008 feature film]] ''[[Flash of Genius (film)|Flash of Genius]]'' based on a 1993 [[New Yorker Magazine|New Yorker]] article that covered the legal battle. In March 1970, French automotive manufacturer [[Citroën]] introduced more advanced [[rain]]-sensitive intermittent windscreen wipers on its [[Citroën SM|SM model]]. When the intermittent function was selected, the wiper would make one sweep. If the windscreen was relatively dry, the wiper motor drew high [[Electric current|current]], which would set the control [[Electric Circuit|circuit]] timer to a long delay for the next wipe. If the motor drew little current, it indicated that the glass was still wet, and would set the timer to minimize the delay. == Power == [[File:Nahverkehrsmunseum-Triebwagen-431-DSC 6417.jpg|thumb|[[Pneumatic motor]] drive on a railroad locomotive windscreen wiper. The lever on the motor operates a valve to supply pressurized air.]] Wipers may be powered by a variety of means, although most in use today are powered by an [[electric motor]] through a series of mechanical components, typically two [[4-bar linkage]]s in series or [[Parallel circuits|parallel]]. Vehicles with air-operated brakes sometimes use [[pneumatic]] wipers, powered by tapping a small amount of pressurized air from the brake system to a small air operated motor mounted on or just above the windscreen. These wipers are activated by opening a valve which allows pressurized air to enter the motor. Early wipers were often driven by a [[vacuum motor]] powered by [[manifold vacuum]]. This had the drawback that manifold vacuum varies depending on [[throttle]] position, and is almost non-existent under wide-open throttle, when the wipers would slow down or even stop. That problem was overcome somewhat by using a combined fuel/vacuum booster pump. Some cars, mostly from the 1960s and 1970s, had variable-speed, hydraulically-driven wipers, most notably the '61–'69 [[Lincoln Continental]],<ref>{{cite web|url=https://autouniversum.wordpress.com/2014/06/25/10186/|title=The Cars of James Bond: Lincoln Continental|date=25 June 2014|website=wordpress.com|access-date=5 April 2018}}</ref> '69–'71 [[Lincoln Continental Mark III]] (but not all '70 models),<ref>{{cite web|url=http://automotivemileposts.com/contentsmark3.html|title=Automotive Mileposts, 1969-1971 Lincoln Continental Mark III|access-date=1 June 2020}}</ref> and '63–'71 [[Ford Thunderbird]].<ref>{{cite web|url=http://automotivemileposts.com/contentstbird.html|title=Automotive Mileposts, 1955-1979 Ford Thunderbird|access-date=1 June 2020|archive-date=21 July 2011|archive-url=https://web.archive.org/web/20110721174124/http://automotivemileposts.com/contentstbird.html|url-status=dead}}</ref> These were powered by the same hydraulic pump also used for the power steering mechanism. On the earlier [[Citroën 2CV]], the windscreen wipers were powered by a purely mechanical system, a cable connected to the transmission; to reduce cost, this cable also powered the speedometer. The wipers' speed was therefore variable with car speed. When the car was stationary, the wipers were not powered, but a handle under the speedometer allowed the driver to power them by hand.{{citation needed|date=June 2011}} == Shape == [[File:Patent US2596063A Illustration.png|thumb|Illustration showing the construction of multi-branched windshield wiper blade holder]] Most early wipers used a rubber blade attached to a flat metal base.

(Fig. 2)]] [[File:Transperth Volgren CR225L bodied Mercedes-Benz O405NH CNG.jpg|thumb|Pantograph windscreen wipers (Fig. 6) used on [[Mercedes-Benz O405|Mercedes-Benz O 405 NH]]]] [[File:Daf_A.Reijerse_&_Zn._Wassenaar.jpg|thumb|right|Triple windshield wipers (Fig.7) used on a DAF XF truck]] Most wipers are of the pivot (or radial) type: they are attached to a single arm, which in turn is attached to the motor. These are commonly found on many cars, trucks, trains, boats, airplanes, etc. Modern windscreen wipers usually move in parallel (Fig. 1, below). However, various [[Mercedes-Benz]] models and other cars such as the [[Volkswagen Sharan]] employ wipers configured to move in opposite directions (Fig. 2), which is mechanically more complex but can avoid leaving a large unwiped corner of the windscreen in front of the front-seat passenger. A cost benefit to the auto-maker occurs when wipers configured to move in opposite directions do not need to be repositioned for cars exported to [[right hand drive]] countries such as the UK and Japan. Another wiper design (Fig. 6) is pantograph-based, used on many commercial vehicles, especially buses with large windscreens. Pantograph wipers feature two arms for each blade, with the blade assembly itself supported on a horizontal bar connecting the two arms. One of the arms is attached to the motor, while the other is on an idle pivot.{{Citation needed|date=October 2010}} The pantograph mechanism, while being more complex, allows the blade to cover more of the windscreen on each wipe. However, it also usually requires the wiper to be "parked" in the middle of the windscreen, where it may partially obstruct the driver's view when not in use. A few models of automobile sometimes employ a pantograph arm on the driver's side and a normal arm for the passenger. The Triumph Stag, Lexus and several US makes employ this method to cover more glass area where the windscreen is quite wide but also very shallow. The reduced height of the windscreen would need the use of short wiper arms which would not have the reach to the edge of the windscreen. A simple single-blade setup with a center pivot (Fig. 4) is commonly used on rear windscreens, as well as on the front of some cars. [[Mercedes-Benz]] pioneered a system (Fig. 5) called the "Monoblade", based on [[cantilever]]s, in which a single arm extends outward to reach the top corners of the windscreen, and pulls in at the ends and middle of the stroke, sweeping out a somewhat M-shaped path. This way, a single blade is able to cover more of the windscreen, displacing any residual streaks away from the centre of the windscreen. Some larger cars in the late '70s and early '80s, especially [[Right- and left-hand traffic#Driver seating position|LH driver]] American cars{{Citation needed|date=October 2010}}, had a pantograph wiper on the driver's side, with a conventional pivot on the passenger side. Asymmetric wiper arrangements are usually configured to clear more windscreen area on the driver's side, and so are mostly mirrored for left and right-hand-drive vehicles (for example, Fig. 1 vs. Fig 10). One exception is found on the second generations of the [[Renault Clio]], [[Renault Twingo|Twingo]] and [[Renault Scénic|Scénic]] as well as [[BMW]]'s [[BMW 5 Series (E60)|E60 5 Series]] and [[BMW 6 Series (E63)|E63 6 Series]], the [[Peugeot 206]] and the [[Nissan Almera Tino]], where the wipers always sweep towards the left. On right-hand-drive models, a linkage allows the right-hand wiper to move outwards towards the corner of the windscreen and clear more area. <gallery mode="packed"> File:scheibenwischer1.svg| Fig. 1: Most common geometry, found on vast majority of vehicles, mainly [[Right- and left-hand traffic|LHD]] cars;

In late 1968, Chevrolet introduced high pressure fluid headlamp washers on a variety of their 1969 models. In 1970, [[Saab Automobile]] introduced [[headlight]] wipers across their product range. These operated on a horizontal reciprocating mechanism, with a single motor. They were later superseded by a radial spindle action wiper mechanism, with individual motors on each headlamp. In 1972, headlamp cleaning systems became mandatory in Sweden. Headlamp wipers have all but disappeared today with most modern designs relying solely on pressurized fluid spray to clean the headlights. This reduces manufacturing cost, minimizes aerodynamic drag, and complies with EU regulations limiting headlamp wiper use to glass-lensed units only (the majority of lenses today are made of plastic.) == Other features == [[File:Wischwaschanlageinaktion.jpg|thumb|upright|Windscreen washer in operation]] === Windscreen washer === {{See also|Windscreen washer fluid}} Most windscreen wipers operate together with a windscreen washer; a [[pump]] that supplies a mixture of water, [[ethanol|alcohol]], and [[detergent]] (a blend called [[windscreen washer fluid]]) from a tank to the windscreen. The fluid is dispensed through small [[nozzle]]s mounted on the [[Hood (vehicle)|hood]]. Conventional nozzles are usually used, but some designs use a [[fluidic]] [[oscillator]] to disperse the fluid more effectively. In warmer climates, water may also work, but it can freeze in colder climates, damaging the pump. Although automobile [[antifreeze]] is chemically similar to windscreen wiper fluid, it should not be used because it can damage paint. The earliest documented idea for having a windscreen wiper unit hooked up to a windscreen washer fluid reservoir was in 1931, Richland Auto Parts Co, Mansfield, Ohio.<ref>[https://books.google.com/books?id=u-IDAAAAMBAJ&dq=Popular+Mechanics+1931+curtiss&pg=PA248 Windshield Freed Of Snow With Alcohol Wiper", February 1931, Popular Mechanics] article bottom half of page</ref><ref>{{cite news |title=car detailing services |url=https://www.bowtiedetailing.com/}}</ref> Uruguayan racecar driver and mechanic [[Héctor Suppici Sedes]] developed a windscreen washer in the late 1930s.<ref>[http://archivo.lavoz.com.ar/2001/0101/nota8051_1.htm Supicci Sedes, un espíritu creador] - La Voz del Interior, 1 January 2001</ref> Since 2012, nozzles are replaced on some cars (Tesla, Volvo XC60 2018-2021, Citroen C4 Cactus) by a system called AquaBlade, developed by the company Valeo. This system supplies the washing liquid directly from the spoiler element of the wiper blade. This system suppresses visual disturbances during driving and so reduces the reaction time of the driver in case of incident.<ref>ATZ, Automobiltechnische Zeitschrift, June 2015</ref> === Hidden wipers === Some larger cars are equipped with '''hidden wipers''' (or '''depressed-park wipers'''). When wipers are switched off in standard non-hidden designs, a "parking" mechanism or circuit moves the wipers to the lower extreme of the wiped area near the bottom of the windscreen, but still in sight. For designs that hide the wipers, the windscreen extends below the rear edge of the bonnet. The wipers park themselves below the wiping range at the bottom of the windscreen, but out of sight. Late model vehicles that hide wiper blades under the windscreen need to be placed in a service position in order to lift the wiper blade from the windscreen using the wiper service position. === Rain-sensing wipers === Some vehicles are now available with automatic or driver-programmable windscreen wipers that detect the presence and amount of rain using a [[rain sensor]]. The sensor automatically adjusts the speed and frequency of the blades according to the amount of rain detected. These controls usually have a manual override. Rain-sensing windscreen wipers appeared on various models in the late 20th century, one of the first being the [[Citroën SM]]. {{As of|2006|alt=As of early 2006}}, rain-sensing wipers are optional or standard on all [[Cadillac]]s and most [[Volkswagen]]s, and are available on many other mainstream manufacturers. The rain-sensing wipers system currently employed by most car manufacturers today was originally invented and patented in 1978 by Australian, Raymond J. Noack, see U.S. Patents 4,355,271 and 5,796,106. The original system automatically operated the wipers, lights and windscreen washers. ==Bladeless alternatives== [[File:Rotating windshield wiper.jpg|thumb|[[Clear view screen]] provides a window of visibility, even in rough seas.]] A common alternative design used on ships, called a [[clear view screen]], avoids the use of rubber wiper blades. A round portion of the windscreen has two layers, the outer one of which is spun at high speed to shed water. High speed aircraft may use [[bleed air]] which uses compressed air from the turbine engine to remove water, rather than mechanical wipers, to save weight and drag.{{citation needed|date=September 2014}} Effectiveness of this method also depends on [[hydrophobic|water-repellent]] glass treatments similar to [[Rain-X]]. == Legislation == Many jurisdictions have legal requirements that vehicles be equipped with windscreen wipers. Windscreen wipers may be a required safety item in auto [[safety inspection]]s.

The arm is powered by a <a href="/enwiki/wiki/Motor" class="mw-redirect" title="Motor">motor</a>, often an <a href="/enwiki/wiki/Electric_motor" title="Electric motor">electric motor</a>, although <a href="/enwiki/wiki/Pneumatic_power" class="mw-redirect" title="Pneumatic power">pneumatic power</a> is also used for some vehicles. The blade is swung back and forth over the glass, pushing water, other <a href="/enwiki/wiki/Precipitation" title="Precipitation">precipitation</a>, or any other impediments to visibility from its surface. The speed is usually adjustable on vehicles made after 1969, with several continuous rates and often one or more <i>intermittent</i> settings. Most personal automobiles use two synchronized <i>radial</i>-type arms, while many commercial vehicles use one or more <i><a href="/enwiki/wiki/Pantograph" title="Pantograph">pantograph</a></i> arms. </p><p>On some vehicles, a <b>windscreen washer</b> system is also used to improve and expand the function of the wiper(s) to dry or icy conditions. This system sprays water, or an <a href="/enwiki/wiki/Antifreeze" title="Antifreeze">antifreeze</a> <a href="/enwiki/wiki/Windshield_washer_fluid" title="Windshield washer fluid">window washer fluid</a>, at the windscreen using several well-positioned <a href="/enwiki/wiki/Nozzle" title="Nozzle">nozzles</a>. This system helps remove dirt or dust from the windscreen when used in concert with the wiper blades. When antifreeze washer fluid is used, it can help the wipers remove snow or ice. For these types of winter conditions, some vehicles have additional <a href="/enwiki/wiki/Heating,_ventilation,_and_air_conditioning" title="Heating, ventilation, and air conditioning">heaters</a> aimed at the windows, embedded <a href="/enwiki/wiki/Heating_element" title="Heating element">heating wire(s)</a> in the glass, or embedded <a href="/enwiki/wiki/Heating_element" title="Heating element">heating wire(s)</a> in the wiper blade; these <a href="/enwiki/wiki/Defogger" title="Defogger">defroster systems</a> can melt ice or help to keep snow and ice from building up on the windscreen.

Similar to current automotive wiper designs, his invention involves "usually two of these wipers, and they can be secured to the frame below the front board of the vehicle or behind the housing surrounding the window in position to be out of sight and in such manner that one will scrape off the heaviest part of the substance collected upon the glass." His patent illustration shows a circular window, although the patent notes "it is not essential that the glass be circular in form." </p><p>Other early designs for the windscreen wiper are credited to Polish concert <a href="/enwiki/wiki/Pianist" title="Pianist">pianist</a> <a href="/enwiki/wiki/J%C3%B3zef_Hofmann" class="mw-redirect" title="Józef Hofmann">Józef Hofmann</a>,<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">&#91;</span>2<span class="cite-bracket">&#93;</span></a></sup> and to Mills Munitions, <a href="/enwiki/wiki/Birmingham" title="Birmingham">Birmingham</a>, who also claimed to have been the first to patent windscreen wipers in England.

These are commonly found on many cars, trucks, trains, boats, airplanes, etc. </p><p>Modern windscreen wipers usually move in parallel (Fig. 1, below). However, various <a href="/enwiki/wiki/Mercedes-Benz" title="Mercedes-Benz">Mercedes-Benz</a> models and other cars such as the <a href="/enwiki/wiki/Volkswagen_Sharan" title="Volkswagen Sharan">Volkswagen Sharan</a> employ wipers configured to move in opposite directions (Fig. 2), which is mechanically more complex but can avoid leaving a large unwiped corner of the windscreen in front of the front-seat passenger.

Pantograph wipers feature two arms for each blade, with the blade assembly itself supported on a horizontal bar connecting the two arms. One of the arms is attached to the motor, while the other is on an idle pivot.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">&#91;<i><a href="/enwiki/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources. (October 2010)">citation needed</span></a></i>&#93;</sup> The pantograph mechanism, while being more complex, allows the blade to cover more of the windscreen on each wipe. However, it also usually requires the wiper to be "parked" in the middle of the windscreen, where it may partially obstruct the driver's view when not in use. A few models of automobile sometimes employ a pantograph arm on the driver's side and a normal arm for the passenger. The Triumph Stag, Lexus and several US makes employ this method to cover more glass area where the windscreen is quite wide but also very shallow. The reduced height of the windscreen would need the use of short wiper arms which would not have the reach to the edge of the windscreen. </p><p>A simple single-blade setup with a center pivot (Fig. 4) is commonly used on rear windscreens, as well as on the front of some cars. <a href="/enwiki/wiki/Mercedes-Benz" title="Mercedes-Benz">Mercedes-Benz</a> pioneered a system (Fig. 5) called the "Monoblade", based on <a href="/enwiki/wiki/Cantilever" title="Cantilever">cantilevers</a>, in which a single arm extends outward to reach the top corners of the windscreen, and pulls in at the ends and middle of the stroke, sweeping out a somewhat M-shaped path. This way, a single blade is able to cover more of the windscreen, displacing any residual streaks away from the centre of the windscreen. </p><p>Some larger cars in the late '70s and early '80s, especially <a href="/enwiki/wiki/Right-_and_left-hand_traffic#Driver_seating_position" class="mw-redirect" title="Right- and left-hand traffic">LH driver</a> American cars<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">&#91;<i><a href="/enwiki/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

Asymmetric wiper arrangements are usually configured to clear more windscreen area on the driver's side, and so are mostly mirrored for left and right-hand-drive vehicles (for example, Fig. 1 vs. Fig 10).

In late 1968, Chevrolet introduced high pressure fluid headlamp washers on a variety of their 1969 models. In 1970, <a href="/enwiki/wiki/Saab_Automobile" title="Saab Automobile">Saab Automobile</a> introduced <a href="/enwiki/wiki/Headlight" class="mw-redirect" title="Headlight">headlight</a> wipers across their product range. These operated on a horizontal reciprocating mechanism, with a single motor. They were later superseded by a radial spindle action wiper mechanism, with individual motors on each headlamp. In 1972, headlamp cleaning systems became mandatory in Sweden. </p><p>Headlamp wipers have all but disappeared today with most modern designs relying solely on pressurized fluid spray to clean the headlights. This reduces manufacturing cost, minimizes aerodynamic drag, and complies with EU regulations limiting headlamp wiper use to glass-lensed units only (the majority of lenses today are made of plastic.) </p> <div class="mw-heading mw-heading2"><h2 id="Other_features">Other features</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/enwiki/w/index.php?title=Windscreen_wiper&amp;action=edit&amp;section=12" title="Edit section: Other features"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/enwiki/wiki/File:Wischwaschanlageinaktion.jpg" class="mw-file-description"><img src="/upwiki/wikipedia/commons/thumb/b/b8/Wischwaschanlageinaktion.jpg/170px-Wischwaschanlageinaktion.jpg" decoding="async" width="170" height="227" class="mw-file-element" srcset="/upwiki/wikipedia/commons/thumb/b/b8/Wischwaschanlageinaktion.jpg/255px-Wischwaschanlageinaktion.jpg 1.5x, /upwiki/wikipedia/commons/thumb/b/b8/Wischwaschanlageinaktion.jpg/340px-Wischwaschanlageinaktion.jpg 2x" data-file-width="1200" data-file-height="1600" /></a><figcaption>Windscreen washer in operation</figcaption></figure> <div class="mw-heading mw-heading3"><h3 id="Windscreen_washer">Windscreen washer</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/enwiki/w/index.php?title=Windscreen_wiper&amp;action=edit&amp;section=13" title="Edit section: Windscreen washer"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">See also: <a href="/enwiki/wiki/Windscreen_washer_fluid" class="mw-redirect" title="Windscreen washer fluid">Windscreen washer fluid</a></div> <p>Most windscreen wipers operate together with a windscreen washer; a <a href="/enwiki/wiki/Pump" title="Pump">pump</a> that supplies a mixture of water, <a href="/enwiki/wiki/Ethanol" title="Ethanol">alcohol</a>, and <a href="/enwiki/wiki/Detergent" title="Detergent">detergent</a> (a blend called <a href="/enwiki/wiki/Windscreen_washer_fluid" class="mw-redirect" title="Windscreen washer fluid">windscreen washer fluid</a>) from a tank to the windscreen.
