Pullstring
A pullstring (pull string, pull-string), pullcord (pull cord, pull-cord), or pullchain (pull-chain, pull chain) is a string, cord, or chain wound on a spring-loaded spindle that engages a mechanism when it is pulled. It is most commonly used in toys and motorized equipment. More generally and commonly, a pullstring can be any type of string, cord, rope, or chain, attached to an object in some way used to pull or mechanically manipulate part of it.
Perhaps the simplest pullstring toy is the yo-yo (c. 460 BCE). The jumping jack is a more complicated animated puppet paper doll that uses a pullstring to move its arms and legs up and down. Trompos and some spinning tops use a string that is wound around the top and then pulled to make it spin.
More recent toys include dolls, such as Chatty Cathy (1959), Charmin' Chatty (1963), Talking Tamu (1970), Look Around Crissy (1972), Sky Dancers (1994), and Sheriff Woody (from the Toy Story franchise), that have a pullstring built into them that activates a speaker when it is pulled, causing the doll to say a built-in phrase. The Blythe doll (1972) has a pullstring that changes the doll's eye color. Other non-doll toys like See 'n Say (1965).
The earliest patent with a pullstring included in it is an 1886 "Toy Bowling-Alley".
Many motorized lawn mowers, chainsaws, portable generators, and portable outboard motors use a pullstring or pullcord attached to a handle as a manual ignition device. Some vehicle engines are also started with pullchains, such as the early-1900s Puckridge, or pullcords, like the pre-release version of the Citroën 2CV car, and the DKW RT 125 scooter. Early jet engines such as the Junkers Jumo 004 used a Riedel two-stroke starter motor actuated by a pullcord.
Some grenades such as the German Models 24, 39, and 43 have pullcords. Some machine guns such as the M73 machine gun and M85 machine gun use a pullchain to charge and/or fire them. The Kord machine gun uses a device to cock the weapon.
Various Booby trap weapons and devices have used cords/cables.
A train's emergency brake can be a cord or chain that will stop the train when pulled. Some transit buses and trams/trolleys have a pullcord, also known as a bell cord, that a passenger can pull to signal the driver that they are requesting a stop. Many newer vehicles now use buttons to request stops instead. The Jaguar XK120 sports car's doors have no external handles so it uses an interior pullcord instead.
