DO NOT LET THEM SLAP BACK DOWN AGAINST THE GLASS. DO NOT TURN THEM BACK ON OR TURN ON THE KEY WHILE THEY ARE RAISED OFF THE GLASS. Replacing windshield wipers isn't supposed to be this difficult. It's easy to try to put them on backwards or upside down, since generally the attachment point can.

A train windscreen wiper in operationA windshield wiper or windscreen wiper is a device used to remove rain, snow, ice and debris from a. Almost all, including, and with a —and some —are equipped with one or more such wipers, which are usually a legal requirement.A wiper generally consists of a metal arm; one end, the other end has a long rubber blade attached to it. The arm is powered by a, often an, although is also used for some vehicles. The blade is swung back and forth over the glass, pushing water, other, or any other impediments to visibility, from its surface. On vehicles made after 1969, the speed is normally adjustable, with several continuous speeds, and often one or more intermittent settings.

Most personal automobiles use two synchronized radial-type arms, while many commercial vehicles use one or more arms.On some vehicles, a windscreen/windshield 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 window washer fluid, at the windscreen using several well-positioned. This system helps remove dirt or dust from the windscreen when it is 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 aimed at the windows, or embedded in the glass; these help to keep snow and ice from building up on the windscreen. Less frequently, miniature wipers are installed on to ensure that they function optimally. Capwell, 1898One of the earliest recorded patents for the windscreen wiper is by George J.

Capewell of Hartford Connecticut, which was filed on August 6, 1896. His invention was for an automated, motorised, wiper for 'cars, locomotives, and such land-vehicles'.Other early designs for the windscreen wiper are credited to Polish concert, and Mills Munitions, 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;, 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 of. Anderson's 1903 window cleaner designAmerican inventor is popularly credited with devising the first operational windscreen wiper in 1903.

In Anderson's patent, she called her invention a 'window cleaning device' for electric cars and other vehicles. Operated via a lever from inside a vehicle, her version of windscreen wipers closely resembles the windscreen wiper found on many early car models. Anderson had a model of her design manufactured, then filed a patent (US 743,801) on June 18, 1903 that was issued to her by the US Patent Office on November 10, 1903. Apjohn's 1903 window cleaning apparatus designIrish born inventor James Henry Apjohn (1845–1914) patented an 'Apparatus for Cleaning Carriage, Motor Car and other Windows' which was stated to use either brushes or wipers and could be either motor driven or hand driven. The brushes or wipers were intended to clean either both up and down or in just one direction on a vertical window. Apjohn's invention had a priority date in the UK of 9 October 1903.(1886-1968) formed the Tri-Continental Corporation in 1917.

This company introduced the first windscreen wiper, Rain Rubber, for the slotted, two-piece windscreens found on many of the automobiles of the time. Today Products is one of the world's largest manufacturers of windscreen wipers. has the world's biggest windscreen wiper factory in, Belgium, which produces 350,000 wiper blades every day. The first automatic electric wiper arms were patented in 1917 by Charlotte Bridgwood.Inventor William M. Folberth and his brother, Fred, applied for a patent for an automatic windscreen wiper apparatus in 1919, which was granted in 1922.

It was the first automatic mechanism to be developed by an American, but the original invention is attributed by others to Hawaiian, Ormand Wall. Trico later settled a patent dispute with Folberth and purchased Folberth's Cleveland company, the Folberth Auto Specialty Co. 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 (variable-rate wipers) might have been Raymond Anderson, who, in 1923, proposed an design. (US Patent 1,588,399). In 1958, Oishei et al. Filed a describing not only electro-mechanical, but also and designs.

(US Patent 2,987,747). Then, in 1961, John Amos, an engineer for the UK company, filed the first patent application in the UK for a design. (US patent 3,262,042).In 1963, another form of intermittent wiper was invented by, an engineering professor at in, Michigan. Kearns's design was intended to mimic the function of the, which only once every few seconds.

In 1963, Kearns built his first intermittent wiper system using off-the-shelf electronic components. In the Kearns design, the interval between wipes was determined by the; when the charge in the reached a certain, the capacitor was discharged, activating the wiper motor for one cycle. Kearns showed his wiper to the and proposed that they manufacture the design.

Ford rejected Kearns' proposal at the time, but later offered a similar design as an option on the company's, beginning with the 1969 models. Kearns sued Ford in a multi-year that Kearns eventually won in court, inspiring the.In March 1970, introduced rain-sensitive intermittent windscreen wipers on their. When the intermittent function was selected, the wiper would make one swipe. If the windscreen was relatively dry, the wiper motor drew high, which set the control circuit timer to delay the next wipe longest. If the motor drew little current, it indicated that the glass was wet and would set the timer to minimize the delay.Power.

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 through a series of mechanical components, typically two in series or.Vehicles with air operated brakes sometimes use 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 powered. This had the drawback that manifold vacuum varies depending on position, and is almost non-existent under wide-open throttle, when the wipers would slow down or even stop. This problem was overcome somewhat by using a combined fuel/vacuum booster pump.Some cars, mostly from the 1960s and 1970s, had hydraulically driven wipers, most notably the '61-'69.On the earlier, 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 waiting at an intersection, the wipers were not powered, but a handle under the speedometer allowed the driver to power them by hand.

Geometry. Pantograph windscreen wipers (Fig.

6) used onMost 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.

However, various models and other cars such as the 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 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. 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. Triumph cars, 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. Pioneered a system (Fig. 5) called the 'Monoblade', based on, 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 center of the windscreen.Some larger cars in the late '70s and early '80s, especially American cars , 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.

One exception is found on the second generations of the, and as well as 's and, the and the, 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. 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, introduced 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.

Provides a window of visibility, even in rough seasA common alternative design used on ships, called a, 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 which uses compressed air from the turbine engine to remove water, rather than mechanical wipers, to save weight and drag. Effectiveness of this method also depends on glass treatments similar to.Legislation Many jurisdictions have legal requirements that vehicles be equipped with windscreen wipers. Windscreen wipers may be a required safety item in auto. Some US states have a 'wipers on, lights on' rule for cars. See also.Notes.
