A paper clip (or sometimes paperclip) is a device used to hold sheets of paper together, usually made of steel wire bent to a looped shape. Most paper clips are variations of the Gem type introduced in the 1890s or earlier, characterized by the almost two full loops made by the wire. Common to paper clips proper is their utilization of torsion and elasticity in the wire, and friction between wire and paper. When a moderate number of sheets are inserted between the two "tongues" of the clip, the tongues will be forced apart and cause torsion in the bend of the wire to grip the sheets together.
Steel is an alloy of iron and carbon, and sometimes other elements. Because of its high tensile strength and low cost, it is a major component used in buildings, infrastructure, tools, ships, automobiles, machines, appliances, and weapons.
A wire is a single, usually cylindrical, flexible strand or rod of metal. Wires are used to bear mechanical loads or electricity and telecommunications signals. Wire is commonly formed by drawing the metal through a hole in a die or draw plate. Wire gauges come in various standard sizes, as expressed in terms of a gauge number. The term wire is also used more loosely to refer to a bundle of such strands, as in "multistranded wire", which is more correctly termed a wire rope in mechanics, or a cable in electricity.
In the field of solid mechanics, torsion is the twisting of an object due to an applied torque. Torsion is expressed in either the Pascal (Pa), an SI unit for newtons per square metre, or in pounds per square inch (psi) while torque is expressed in newton metres (N·m) or foot-pound force (ft·lbf). In sections perpendicular to the torque axis, the resultant shear stress in this section is perpendicular to the radius.
Paper clips usually have an oblong shape with straight sides, but may also be triangular or circular, or have more elaborate shapes. The most common material is steel or some other metal, but moulded plastic is also used. Some other kinds of paper clip use a two-piece clamping system. Recent innovations include multi-colored plastic-coated paper clips and spring-fastened binder clips.
A metal is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable or ductile. A metal may be a chemical element such as iron, or an alloy such as stainless steel.
Plastic is material consisting of any of a wide range of synthetic or semi-synthetic organic compounds that are malleable and so can be molded into solid objects.
A spring is an elastic object that stores mechanical energy. Springs are typically made of spring steel. There are many spring designs. In everyday use, the term often refers to coil springs.
According to the Early Office Museum, the first patent for a bent wire paper clip was awarded in the United States to Samuel B. Fay in 1867. This clip was originally intended primarily for attaching tickets to fabric, although the patent recognized that it could be used to attach papers together.Fay received U.S. patent 64,088 on April 23, 1867. Although functional and practical, Fay's design along with the 50 other designs patented prior to 1899 are not considered reminiscent of the modern paperclip design known today. Another notable paper clip design was also patented in the United States by Erlman J. Wright in 1877. This clip was advertised at that time for use in fastening newspapers.
The most common type of wire paper clip still in use, the Gem paper clip, was never patented, but it was most likely in production in Britain in the early 1870s by "The Gem Manufacturing Company", according to the American expert on technological innovations, Professor Henry J. Petroski.He refers to an 1883 article about "Gem Paper-Fasteners", praising them for being "better than ordinary pins" for "binding together papers on the same subject, a bundle of letters, or pages of a manuscript". Since the 1883 article had no illustration of this early "Gem", it may have been different from modern paper clips of that name.
The United Kingdom, officially the United Kingdom of Great Britain and Northern Ireland but more commonly known as the UK or Britain, is a sovereign country lying off the north-western coast of the European mainland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland and many smaller islands. Northern Ireland is the only part of the United Kingdom that shares a land border with another sovereign state—the Republic of Ireland. Apart from this land border, the United Kingdom is surrounded by the Atlantic Ocean, with the North Sea to the east, the English Channel to the south and the Celtic Sea to the south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of 242,500 square kilometres (93,600 sq mi), the United Kingdom is the 78th-largest sovereign state in the world. It is also the 22nd-most populous country, with an estimated 66.0 million inhabitants in 2017.
Henry Petroski is an American engineer specializing in failure analysis. A professor both of civil engineering and history at Duke University, he is also a prolific author. Petroski has written over a dozen books – beginning with To Engineer is Human: The Role of Failure in Successful Design (1985) and including a number of titles detailing the industrial design history of common, everyday objects, such as pencils, paper clips, and silverware. His first book was made into the film When Engineering Fails.. He is a frequent lecturer and a columnist for the magazines American Scientist and Prism.
The earliest illustration of its current form is in an 1893 advertisement for the "Gem Paper Clip".In 1904 Cushman & Denison registered a trademark for the "Gem" name in connection with paper clips. The announcement stated that it had been used since March 1, 1892, which may have been the time of its introduction in the United States. Paper clips are still sometimes called "Gem clips", and in Swedish the word for any paper clip is "gem".
Definite proof that the modern type of paper clip was well known in 1899 at the latest, is the patent granted to William Middlebrook of Waterbury, Connecticut on April 27 of that year for a "Machine for making wire paper clips." The drawing clearly shows that the product is a perfect clip of the Gem type.The fact that Middlebrook did not mention it by name, suggests that it was already well known at the time. Since then countless variations on the same theme have been patented. Some have pointed instead of rounded ends, some have the end of one loop bent slightly to make it easier to insert sheets of paper, and some have wires with undulations or barbs to get a better grip. In addition, purely aesthetic variants have been patented, clips with triangular, star, or round shapes. But the original Gem type has for more than a hundred years proved to be the most practical, and consequently by far the most popular. Its qualities—ease of use, gripping without tearing, and storing without tangling—have been difficult to improve upon.
Waterbury is a city in the U.S. state of Connecticut on the Naugatuck River, 33 miles southwest of Hartford and 77 miles northeast of New York City. Waterbury is the second-largest city in New Haven County, Connecticut. As of the 2010 census, Waterbury had a population of 110,366, making it the 10th largest city in the New York Metropolitan Area, 9th largest city in New England and the 5th largest city in Connecticut.
Connecticut is the southernmost state in the New England region of the United States. As of the 2010 Census, it has the highest per-capita income, Human Development Index (0.962), and median household income in the United States. It is bordered by Rhode Island to the east, Massachusetts to the north, New York to the west, and Long Island Sound to the south. Its capital is Hartford and its most populous city is Bridgeport. It is part of New England, although portions of it are often grouped with New York and New Jersey as the Tri-state area. The state is named for the Connecticut River which approximately bisects the state. The word "Connecticut" is derived from various anglicized spellings of an Algonquian word for "long tidal river".
It has been claimed, cm unfolded.though apparently without evidence, that Herbert Spencer, the originator of the term "survival of the fittest", invented the paper clip. Spencer claimed in his autobiography to have invented a "binding-pin" that was distributed by Ackermann & Company, and he shows a drawing of the pin in his Appendix I (following Appendix H). This pin looked more like a modern cotter pin than a modern paper clip, but it was designed to hold sheets of paper together. It is approximately 15
A Norwegian, Johan Vaaler (1866–1910), has erroneously been identified as the inventor of the paper clip. He was granted patents in Germanyand in the United States (1901) for a paper clip of similar design, but less functional and practical, because it lacked the last turn of the wire. Vaaler probably did not know that a better product was already on the market, although not yet in Norway. His version was never manufactured and never marketed, because the superior Gem was already available.
Long after Vaaler's death his countrymen created a national myth based on the false assumption that the paper clip was invented by an unrecognised Norwegian genius. Norwegian dictionaries since the 1950s have mentioned Vaaler as the inventor of the paper clip,and that myth later found its way into international dictionaries and much of the international literature on paper clips.
Vaaler probably succeeded in having his design patented abroad, despite the previous existence of more useful paper clips, because patent authorities at that time were quite liberal and rewarded any marginal modification of existing inventions.Johan Vaaler began working for Alfred J. Bryns Patentkontor in Kristiania in 1892 and was later promoted to office manager, a position he held until his death. As the employee of a patent office, he could easily have obtained a patent in Norway. His reasons for applying abroad are not known; it is possible that he wanted to secure the commercial rights internationally. Also, he may have been aware that a Norwegian manufacturer would find it difficult to introduce a new invention abroad, starting from the small home market.
Vaaler's patents expired quietly, while the "Gem" was used worldwide, including his own country. The failure of his design was its impracticality. Without the two full loops of the fully developed paper clip, it was difficult to insert sheets of paper into his clip. One could manipulate the end of the inner wire so that it could receive the sheet, but the outer wire was a dead end because it could not exploit the torsion principle. The clip would instead stand out like a keel, perpendicular to the sheet of paper. The impracticality of Vaaler's design may easily be demonstrated by cutting off the last outer loop and one long side from a regular Gem clip.
The originator of the Norwegian paper clip myth was an engineer of the Norwegian national patent agency who visited Germany in the 1920s to register Norwegian patents in that country. He came across Vaaler's patent, but failed to detect that it was not the same as the then-common Gem-type clip.In the report of the first fifty years of the patent agency, he wrote an article in which he proclaimed Vaaler to be the inventor of the common paper clip. This piece of information found its way into some Norwegian encyclopedias after World War II.
Events of that war contributed greatly to the mythical status of the paper clip. Patriots wore them in their lapels as a symbol of resistance to the German occupiers and local Nazi authorities when other signs of resistance, such as flag pins or pins showing the cipher of the exiled King Haakon VII of Norway were forbidden. Those wearing them did not yet see them as national symbols, as the myth of their Norwegian origin was not commonly known at the time. The clips were meant to denote solidarity and unity ("we are bound together"). The wearing of paper clips was soon prohibited, and people wearing them could risk severe punishment.
The leading Norwegian encyclopedia mentioned the role of the paper clip as a symbol of resistance in a supplementary volume in 1952, but did not yet proclaim it a Norwegian invention.That information was added in later editions. According to the 1974 edition, the idea of using the paper clip to denote resistance originated in France. A clip worn on a lapel or front pocket could be seen as "deux gaules" (two posts or poles) and be interpreted as a reference to the leader of the French Resistance, General Charles de Gaulle.
The post-war years saw a widespread consolidation of the paper clip as a national symbol. Authors of books and articles on the history of Norwegian technology eagerly seized it to make a thin story more substantial. They chose to overlook the fact that Vaaler's clip was not the same as the fully developed Gem-type clip. 7 m (23 ft) high, was erected on the campus of a commercial college near Oslo in honour of Vaaler, ninety years after his invention was patented. But this monument shows a Gem-type clip, not the one patented by Vaaler. The celebration of the alleged Norwegian origin of the paper clip culminated in 1999, one hundred years after Vaaler submitted his application for a German patent. A commemorative stamp was issued that year, the first in a series to draw attention to Norwegian inventiveness. The background shows a facsimile of the German "Patentschrift". However, the figure in the foreground is not the paper clip depicted on that document, but the much better known "Gem". In 2005, the national biographical encyclopedia of Norway (Norsk biografisk leksikon) published the biography of Johan Vaaler, stating he was the inventor of the paper clip.In 1989 a giant paper clip, almost
Wire is versatile in its nature. Thus a paper clip is a useful accessory in many kinds of mechanical work including computer work: the metal wire can be unfolded with a little force. Several devices call for a very thin rod to push a recessed button which the user might only rarely need. This is seen on most CD-ROM drives as an "emergency eject" should the power fail; also on early floppy disk drives (including the early Macintosh). Various smartphones require the use of a long thin object such as a paper clip to eject the SIM card and some Palm PDAs advise the use of a paper clip to reset the device. The track ball can be removed from early Logitech pointing devices using a paper clip as the key to the bezel. A paper clip bent into a "U" can be used to start an ATX PSU without connecting it to a motherboard (connect the green to a black on the motherboard header). One or more paper clips can make a loopback device for a RS232 interface (or indeed many interfaces). A paper clip could be installed in a Commodore 1541 disk-drive as a flexible head-stop. A paper clip can be used (unsafely) to temporarily bridge a blown fuse. The steel wire from a paperclip can be used in dentistry to form a dental post.
Paper clips can be bent into a crude but sometimes effective lock picking device. [ citation needed ]Some types of handcuffs can be unfastened using paper clips. There are two approaches. The first one is to unfold the clip in a line and then twist the end in a right angle, trying to imitate a key and using it to lift the lock fixator. The second approach, which is more feasible but needs some practice, is to use the semi-unfolded clip kink for lifting when the clip is inserted through the hole where the handcuffs are closed.

A hair pin or hairpin is a long device used to hold a person's hair in place. It may be used simply to secure long hair out of the way for convenience or as part of an elaborate hairstyle or coiffure. The earliest evidence for dressing the hair may be seen in carved "venus figurines" such as the Venus of Brassempouy and the Venus of Willendorf. The creation of different hairstyles, especially among women, seems to be common to all cultures and all periods and many past, and current, societies use hairpins.
A clothes hanger, coat hanger, or coathanger, is a device in the shape of:
A breadboard is a construction base for prototyping of electronics. Originally it was literally a bread board, a polished piece of wood used for slicing bread. In the 1970s the solderless breadboard became available and nowadays the term "breadboard" is commonly used to refer to these.
Johan Vaaler was a Norwegian inventor and patent clerk. He has often erroneously been identified with the invention of the common paper clip, known to all office employees for more than a hundred years. He is also the uncle of renowned vacuum designer Arnold Vaaler.
A staple is a type of two-pronged fastener, usually metal, used for joining or binding materials together. Large staples might be used with a hammer or staple gun for masonry, roofing, corrugated boxes and other heavy-duty uses. Smaller staples are used with a stapler to attach pieces of paper together; such staples are a more permanent and durable fastener for paper documents than the paper clip.
A stapler is a mechanical device that joins pages of paper or similar material by driving a thin metal staple through the sheets and folding the ends. Staplers are widely used in government, business, offices, homes and schools.
A crocodile clip is a sprung metal clip with long, serrated jaws which is used for creating a temporary electrical connection. This simple mechanical device gets its name from the resemblance of its jaws to that of an alligator's or crocodile's. It is used to connect an electrical cable to a battery or some other component. Functioning much like a spring-loaded clothespin, the clip's tapered, serrated jaws are forced together by a spring to grip an object. When manufactured for electronics testing and evaluation, one jaw of the clip is typically permanently crimped or soldered to a wire, or is bent to form the inner tubular contact of a ~4 mm female banana jack, enabling quick non-permanent connection between a circuit under test and laboratory equipment or to another electrical circuit. The clip is typically covered by a plastic shroud or "boot" to prevent accidental short-circuits.
A binder clip, less commonly known as a banker's clip or foldover clip, is a simple device for binding sheets of paper together. It leaves the paper intact and can be removed quickly and easily, unlike the staple. The term "foldback clip" is used in the United Kingdom to describe this invention. It is also sometimes referred to as a "handbag clip" because, when not in use, its clip can be folded up to look like a handbag.
A staple remover is a device that allows for the quick removal of a staple from a material without causing damage. The best-known form of staple remover, designed for light-gauge staples, consists essentially of a) two opposing, pivot-mounted pairs of thin, steep wedges and b) a spring that returns the device to the open position after use. Although a simple metal wedge can be used for the same purpose, and although some staplers feature such a wedge at their hinge end, use of the wedge tends to tear fragile papers.
A pin is a device used for fastening objects or material together, and can have three sorts of body: a shaft of a rigid inflexible material meant to be inserted in a slot, groove, or hole ; a shaft connected to a head and ending in a sharp tip meant to pierce one or more pieces of soft materials like cloth or paper ; a single strip of a rigid but flexible material whose length has been folded into parallel prongs in such fashion that the middle length of each curves towards the other so that, when anything is inserted between them, they act as a clamp, or two strips of a rigid material bound together by a spring at one end so that, when the spring held open, one can insert some material between the prongs at the other end that, the spring allowed to close, then clamp the inserted material. According to their function, pins can be made of metals, wood, or plastic.
Safety wire or locking-wire is a type of positive locking device that prevents fasteners from loosening or falling out due to vibration and other forces. The presence of safety wiring may also serve to indicate that the fasteners have been properly tightened.
A Fahnestock clip is an early type of spring clamp electrical terminal for connections to bare wires. It is still used in educational electronic kits and teaching laboratories in schools. It is designed to grip a bare wire securely, yet release it with the push of a tab. The clip was patented February 26, 1907 by John Schade Jr., assigned to Fahnestock Electric Co. Less than 2 weeks after the patent was issued they filed for reissue.
The Paper Clips Project, by middle school students from the small southeastern Tennessee town of Whitwell, created a monument for the Holocaust victims of Nazi Germany. It started in 1998 as a simple 8th-grade project to study other cultures, and then evolved into one gaining worldwide attention. At last count, over 30 million paper clips had been received. Paper Clips, an award-winning documentary film about the project, was released in 2004 by Miramax Films.
A cheese knife is a type of kitchen knife specialized for the cutting of cheese. Different cheeses require different knives, according primarily to hardness; most often "cheese knife" refers to a knife designed for soft cheese.
A patent application or patent may contain drawings, also called patent drawings, illustrating the invention, some of its embodiments, or the prior art. The drawings may be required by the law to be in a particular form, and the requirements may vary depending on the jurisdiction.

An R-clip, also known as an R-pin, R-key, hairpin cotter pin, hairpin cotter, bridge pin, hitch pin or spring cotter pin, is a fastener made of a springy material, commonly hardened metal wire, resembling the shape of the letter "R".
A timeline of United States inventions encompasses the ingenuity and innovative advancements of the United States within a historical context, dating from the Colonial Period to the Gilded Age, which have been achieved by inventors who are either native-born or naturalized citizens of the United States. Copyright protection secures a person's right to his or her first-to-invent claim of the original invention in question, highlighted in Article I, Section 8, Clause 8 of the United States Constitution, which gives the following enumerated power to the United States Congress:
A pin-back button or pinback button, pin button, button badge, or simply pin-back or badge, is a button or badge that can be temporarily fastened to the surface of a garment using a safety pin, or a pin formed from wire, a clutch or other mechanism. This fastening mechanism is anchored to the back side of a button-shaped metal disk, either flat or concave, which leaves an area on the front of the button to carry an image or printed message. The word is commonly associated with a campaign button used in the United States and abroad during a political campaign. The first design for a pin-back button in the United States was patented in 1896, and contemporary buttons have many of the same design features.
The Eriksen M/25 was a prototype light machine gun designed and built by the Norwegian gunsmith Johan Emil Barbat Eriksen in 1925. A single prototype of the weapon was manufactured and saw service with the Norwegian Army during the Norwegian Campaign in 1940.
