Who invented the intermittent wipers?
Robert W. Kearns
25 – Robert W. Kearns, the inventor of intermittent windshield wipers, who won multimillion-dollar judgments against Ford Motor and Chrysler for using his idea, died on Feb. 9 at his home in suburban Baltimore. He was 77.
What was Robert Kearns principal argument when he was defending his invention in court?
Mr. Kearns argued that he showed the device, mounted on a Ford Galaxy, to Ford officials in 1963. He also tried to commercialize the invention through a company called the Tann Corporation, but again was unsuccessful. Meanwhile, American car makers began introducing devices similar to his invention around 1969.
When were intermittent windshield wipers invented?
1967
In 1967, Kearns received several patents for his design for wipers that paused between swipes, making them useful in light rain or mist. The invention allows the driver to set the interval at which the wiper sweeps the window.

How long does it take my car wipers to stop?
Hi, my wipers work however they seem to have a mind of their own. When turned on they keep going regardless of setting and eventually stop on there own after about 15 seconds consistently. Sometimes they stop in the middle or other random locations. Once stopped they will only start again when I cycle ignition off and on.
Why do my wipers stop when I turn off ignition?
When turned on they keep going regardless of setting and eventually stop on there own after about 15 seconds consistently. Sometimes they stop in the middle or other random locations. Once stopped they will only start again when I cycle ignition off and on. Any help is help is appreciated. Thank you…
How is the speed of the wiper motor controlled?
The wiper motor speed is controlled by current flow to either the low speed or the high speed set of brushes. The park switch is a single pole, single throw, momentary switch within the wiper motor that is mechanically actuated by the wiper motor transmission components.
Can a faulty wiper be adjusted or repaired?
The wiper module cannot be adjusted or repaired. If any component of the module is faulty or damaged, the entire wiper module unit must be replaced. The wiper module operation is controlled by the battery current inputs received by the wiper motor through the wiper on/off and wiper high/low relays.
How do I Change my wipers to intermittent?
Switch the wipers to the intermittent setting – the wipers will start to sweep the screen as normal. Before the wipers return to the park position, switch them off. Wait, then switch the wipers to intermittent again. The wipers will now work intermittently, using the length of time you waited in step 3 as the delay time.
How does the intermittent wiper relay system work?
This operation is completed thanks to the intermittent wiper relay; an electrical switch that sends a predetermined setting to the wiper module to power the wiper motor. When all of the components involved in the windshield wiper blades work correctly, the system is very convenient.
What to do if your car wipers don’t work?
Replace the fuse box cover and reconnect the battery as necessary. Switch the wipers to the intermittent setting – the wipers will start to sweep the screen as normal. Before the wipers return to the park position, switch them off. Wait, then switch the wipers to intermittent again.
Is there a variable delay for intermittent wipers?
It’s a function that’s so common on modern cars it barely merits a mention: variable delay for the intermittent wipers. Older cars often don’t have the variable delay, but many of them can be upgraded very simply.
