A shirt'" is a cloth garment for the upper body. Originally an item of underwear worn exclusively by men, it has become in American English a catch-all term for almost any upper-body garment other than outerwear such as sweaters or coats, or undergarments such as bras (the term "top" is sometimes used in ladieswear). In British English, a shirt is more specifically a garment with a collar, sleeves with cuffs, and a full vertical opening with buttons; what is known in American English as a dress shirt. History. The world's oldest preserved garment, discovered by Flinders Petrie, is a "highly sophisticated" linen shirt from a First Dynasty Egyptian tomb at Tarkan, "ca." 3000B.C.: "the shoulders and sleeves have been finely pleated to give form-fitting trimness while allowing the wearer room to move. The small fringe formed during weaving along one edge of the cloth has been placed by the designer to decorate the neck opening and side seam." The shirt was an item of men's underwear until the twentieth century. Although the woman's chemise was a closely related garment to the man's, it is the man's garment that became the modern shirt. In the middle ages it was a plain, undyed garment worn next to the skin and under regular garments. In medieval artworks, the shirt is only visible (uncovered) on humble characters, such as shepherds, prisoners, and penitents. In the seventeenth century men's shirts were allowed to show, with much the same erotic import as visible underwear today. In the eighteenth century, instead of underpants, men "relied on the long tails of shirts... to serve the function of drawers. Eighteenth century costume historian Joseph Strutt believed that men who did not wear shirts to bed were indecent. Even as late as 1879, a visible shirt with nothing over it was considered improper. The shirt sometimes had frills at the neck or cuffs. In the sixteenth century, men's shirts often had embroidery, and sometimes frills or lace at the neck and cuffs, and through the eighteenth century long neck frills, or jabots, were fashionable. Colored shirts begin to appear in the early nineteenth century, as can be seen in the paintings of George Caleb Bingham. They were considered casual wear, for lower class workers only, until the twentieth century. For a gentleman, "to wear a sky-blue shirt was unthinkable in 1860 but had become standard by 1920 and, in 1980, constituted the most commonplace event." European and American women began wearing shirts in 1861, when the "Garibaldi Blouse", a red shirt as worn by the freedom fighters under Giuseppe Garibaldi, became fashionable. Types of shirt. Tops that would generally not be considered shirts: Parts of shirts. Many terms are used to describe and differentiate types of shirts (and upper-body garments in general) and their construction. The smallest differences may have significance to a cultural or occupational group. Recently, (late 20th century) it has become common to use tops to carry messages or advertising. Many of these distinctions apply to other upper-body garments, such as coats and sweaters. Cuffs. Shirts with long sleeves may further be distinguished by the cuffs: Other features. Some combinations are not applicable, of course, e.g. a tube top cannot have a collar. Types of shirting Fabrics. There are main two categories of i.e. Natural Fibre and Man-Made Fibre (Synthetics or Petroleum based). Some of Natural Fibre fabric are 100% cotton, Bamboo, Soya, now Organic Cotton widely used in making shirts of high quality. Synthetics fibre are Polyester, Tencel, Viscose etc. These are easy care fabrics, some times low in cost. Polyester mixed with cotton (Polycotton) and 100% cotton are most used in shirting fabrics. Shirts and politics. Redshirts was the name used by Garibaldi's troops in Italian Unification. In 1920s and 1930s, the fascism choose coloured shirts for made explicit its ideology: The screwdriver'" is a device specifically designed to insert and tighten, or to loosen and remove, screws. The screwdriver is made up of a head or tip, which engages with a screw, a mechanism to apply torque by rotating the tip, and some way to position and support the screwdriver. A typical hand screwdriver comprises an approximately cylindrical handle of a size and shape to be held by a human hand, and an axial shaft fixed to the handle, the tip of which is shaped to fit a particular type of screw. The handle and shaft allow the screwdriver to be positioned and supported and, when rotated, to apply torque. Screwdrivers are made in a variety of shapes, and the tip can be rotated manually or by an electric or other motor. A screw has a head with a contour such that an appropriate screwdriver tip can be engaged in it in such a way that the application of sufficient torque to the screwdriver will cause the screw to rotate. History. Gunsmiths still refer to a screwdriver as a "turnscrew", under which name it is an important part of a set of pistols. The name was common in earlier centuries, used by cabinet makers and shipwrights and perhaps other trades. The Cabinet-Maker's screwdriver is one of the longest-established handle forms, somewhat oval or elipsoid in cross section. This is variously attributed to improving grip or preventing the tool rolling off the bench, but there is no reason to suppose these are not rationalisations. The shape has been popular for a couple of hundred years. It is usually associated with a plain head for slotted screws, but has been used with many head forms. "See Also: "The History of Screws Types and variations. There are many types of screw heads, of which the most common are the slotted, Phillips, PoziDriv SupaDriv (crosspoint), Robertson, TORX, and Allen (hex). Screwdrivers come in a large variety of sizes to match those of screws, from tiny jeweler's screwdrivers up. If a screwdriver that is not the right size and type for the screw is used, it is likely that the screw will be damaged in the process of tightening it. This is less important for PoziDriv and SupaDriv, which are designed specifically to be more tolerant of size mismatch. When tightening a screw with force, it is important to press the head hard into the screw, again to avoid damaging the screw. Some manual screwdrivers have a ratchet action whereby the screwdriver blade is locked to the handle for clockwise rotation, but uncoupled for counterclockwise rotation when set for tightening screws; and vice versa for loosening. Many screwdriver designs have a handle with detachable head (the part of the screwdriver which engages with the screw), called "bits" as with drill bits, allowing a set of one handle and several heads to be used for a variety of screw sizes and types. This kind of design has allowed the development of electrically powered screwdrivers, which, as the name suggests, use an electric motor to rotate the bit. In such cases the terminology for power drills is used, e.g. "shank" or "collet". Some drills can also be fitted with screwdriver heads. Manual screw drivers with a spiral ratchet'" mechanism to turn pressure (linear motion) into rotational motion also exist, and predate electric screwdrivers. The user pushes the handle toward the workpiece, causing a pawl in a spiral groove to rotate the shank and the removable bit. The ratchet can be set to rotate left or right with each push, or can be locked so that the tool can be used like a conventional screwdriver. Once very popular, these spiral ratchet drivers, using proprietary bits, have been largely discontinued by manufacturers such as Stanley, although one can still find them at vintage tool auctions. Companies such as Lara Specialty Tools now offer a modernized version that uses standard 1 /4-inch hex shank power tool bits. Since a variety of drill bits are available in this format, it allows the tool to do double duty as a "push drill". Many modern electrical appliances, if they contain screws at all, use screws with heads other than the typical slotted or Phillips styles. TORX is one such pattern that has become very widespread. The main cause of this trend is manufacturing efficiency: TORX and other types are designed so the driver will not slip out of the fastener as will a Phillips driver. (Slotted screws are rarely used in mass-produced devices, since the driver is not inherently centered on the fastener). A benefit disadvantage of non-typical fasteners (depending on your point of view) is that it can be more difficult for users of a device to disassemble it than if more-common head types were used, but TORX and other drivers are widely available. Specialized patterns of security screws are also used, such as the Gamebit head style used in all Nintendo consoles, though drivers for most security heads are, again, readily available. While screwdrivers are designed for the above functions, they are commonly also used as improvised substitutes for pry bars, levers, and hole punches, as well as other tools. There is no such thing as a "left-handed screwdriver", as the device can easily be wielded in either hand. To be sent on an errand to find a left-handed screwdriver is often a test of stupidity, or is used as a metaphor for something useless. The term "Birmingham screwdriver" is used jokingly in the UK to denote a hammer or sledgehammer. The handle and shaft of screwdrivers have changed considerably over time. The design is influenced by both purpose and manufacturing requirements. The "Perfect Handle" screwdriver was first manufactured by HD Smith & Company that operated from 1850 to 1900. Many manufacturers adopted this handle design world wide. The "Flat Bladed" screwdriver was another design composed of drop forged steel with riveted wood handles? Among slotted screwdrivers, there are a couple of major variations at the blade or bit end involving the profile of the blade as viewed face-on. The more common type is sometimes referred to as keystone'", where the blade profile is slightly flared before tapering off at the end. To maximize access in space-restricted applications, the same edges for the "'cabinet'" variety, in contrast, are straight and parallel, meeting the end of the blade at a right angle.
