Pull Chain
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. Toys 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 ...

Look Around Crissy
Crissy is an American fashion doll with a feature to adjust the length of its hair. Crissy was created in the Ideal Toy Corporation's prototype department in 1968. History and concept The creative idea and realization of a doll that “grows” hair originated not at Ideal Toy Company, but at the American Character Doll Company. The Ideal Corporation obtained the patents for the basic mechanism when they acquired them from the American Character Doll Company after that company's 1968 closure."American Character Dolls 1919-1968," DollReference.com. Accessed Dec. 26, 2014. American Character developed and used the concept as early as 1963 in their "Pre-Teen" , and later |
Portable Generator
An engine–generator is the combination of an electrical generator and an engine (prime mover) mounted together to form a single piece of equipment. This combination is also called an ''engine–generator set'' or a ''gen-set''. In many contexts, the engine is taken for granted and the combined unit is simply called a ''generator''. An engine–generator may be a fixed installation, part of a vehicle, or made small enough to be portable. Components In addition to the engine and generator, engine–generators generally include a fuel supply, a constant engine speed regulator (governor) and a generator voltage regulator, cooling and exhaust systems, and lubrication system. Units larger than about 1 kW rating often have a battery and electric starter motor; very large units may start with compressed air either to an air driven starter motor or introduced directly to the engine cylinders to initiate engine rotation. Standby power generating units often include an automatic start ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chainsaw
A chainsaw (or chain saw) is a portable gasoline-, electric-, or battery-powered saw that cuts with a set of teeth attached to a rotating chain driven along a guide bar. It is used in activities such as tree felling, limbing, bucking, pruning, cutting firebreaks in wildland fire suppression, and harvesting of firewood. Chainsaws with specially designed bar-and-chain combinations have been developed as tools for use in chainsaw art and chainsaw mills. Specialized chainsaws are used for cutting concrete during construction developments. Chainsaws are sometimes used for cutting ice; for example, ice sculpture and winter swimming in Finland. History In surgery The origin of chain saws in surgery is debated. A "flexible saw", consisting of a fine serrated link chain held between two wooden handles, was pioneered in the late 18th century (c. 1783–1785) by two Scottish doctors, John Aitken and James Jeffray, for symphysiotomy and excision of diseased bone, respectively. It was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lawn Mower
A lawn mower (also known as a mower, grass cutter or lawnmower) is a device utilizing one or more revolving blades (or a reel) to cut a grass surface to an even height. The height of the cut grass may be fixed by the design of the mower, but generally is adjustable by the operator, typically by a single master lever, or by a lever or nut and bolt on each of the machine's wheels. The blades may be powered by manual force, with wheels mechanically connected to the cutting blades so that when the mower is pushed forward, the blades spin or the machine may have a battery-powered or plug-in electric motor. The most common self-contained power source for lawn mowers is a small (typically one cylinder) internal combustion engine. Smaller mowers often lack any form of propulsion, requiring human power to move over a surface; "walk-behind" mowers are self-propelled, requiring a human only to walk behind and guide them. Larger lawn mowers are usually either self-propelled "walk-behind" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bowling Alley
A bowling alley (also known as a bowling center, bowling lounge, bowling arena, or historically bowling club) is a facility where the sport of bowling is played. It can be a dedicated facility or part of another, such as a Meetinghouse, clubhouse or dwelling house. History By the late 1830s, the Knickerbocker Hotel's bowling alley had opened, with three lanes. Instead of wood, this indoor alley used clay for the bowling lane. By 1850, there were more than 400 bowling alleys in New York City, which earned it the title "bowling capital of North America". Because early versions of bowling were difficult and there were concerns about gambling, the sport faltered. Several cities in the United States regulated bowling due to its association with gambling. In the late 19th century, bowling was revived in many U.S. cities. Alleys were often located in saloon basements and provided a place for working-class men to meet, socialize, and drink alcohol. Bars were and still are a principal fe ...

Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder mus ...

See 'n Say
See 'n Say is an educational toy created by Mattel in 1965 after the success of Chatty Cathy. It was the first Mattel talking toy allowing children to choose the exact phrase as heard. Although the first release focuses on farm animal sounds, it had spawned through many themes from the alphabet, counting, nursery rhymes, to licensed products. As of May 2022, a version of the product was still available from Mattel. History In the 1960s, after introducing a line of talking dolls that said different phrases when a string protruding from their upper back was pulled, Mattel trademarked the word ''chatty''. Several Mattel pull-string talking dolls and toys were packaged in boxes that read "A Chatty Toy" or "A Chatty Doll by Mattel". However, these dolls and toys spoke phrases at random when their "chatty ring" was pulled. See 'N Say, introduced in 1965, was the first Mattel talking toy that allowed children to choose the exact phrase they wanted to hear by adjusting a pointer on the to ...

Blythe (doll)
Blythe is a fashion doll, about 28 cm (11 inch) tall, with an oversized head and large eyes that change color with the pull of a string. It was created in 1972 and was initially only sold for one year in the United States by toy company Kenner (later purchased by Hasbro). In 2001 the Japanese toy company Takara began producing new editions of Blythe dolls. There is a network of hobbyists who customize the doll for resale and create clothing and shoes for Blythe. Enthusiasts share photographs of their work and other types of dolls on the Internet. History Blythe was created in the early seventies by designer Allison Katzman at Marvin Glass and Associates and bought and produced in the United States in 1972 by the now-defunct toy company Kenner. Blythe dolls were only sold for one year in the U.S. (produced in Hong Kong) and also in the UK, Australia and Japan, during 1972. Over time the original "Kenner" Blythe dolls acquired a cult following of collectors and eventuall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loudspeaker
A loudspeaker (commonly referred to as a speaker or speaker driver) is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound. A ''speaker system'', also often simply referred to as a "speaker" or "loudspeaker", comprises one or more such speaker ''drivers'', an enclosure, and electrical connections possibly including a crossover network. The speaker driver can be viewed as a linear motor attached to a diaphragm which couples that motor's movement to motion of air, that is, sound. An audio signal, typically from a microphone, recording, or radio broadcast, is amplified electronically to a power level capable of driving that motor in order to reproduce the sound corresponding to the original unamplified electronic signal. This is thus the opposite function to the microphone; indeed the ''dynamic speaker'' driver, by far the most common type, is a linear motor in the same basic configuration as the dynamic microphone which uses such ...
