PEN (See also:Lat. penna, a See also:feather, pen)  , an See also:instrument for See also:writing or for forming lines with an See also:ink or other coloured fluid . The See also:English word, as well as its equivalents in See also:French (plume) and in See also:German (Feder), originally means a wing-See also:feather, but in See also:ancient times the implements used for producing written characters were not quills . The earliest writing See also:implement was probably the stilus (Gr . 'ypa4As), a pointed See also:bodkin of See also:metal, See also:bone or See also:ivory, used for producing incised or engraved letters on See also:boxwood tablets covered with See also:wax . The calamus (Gr. rchXa,u or) or arundo, the hollow tubular stalk of See also:grasses growing in marshy lands, was the true ancient representative of the See also:modern See also:pen; hollow See also:joints of See also:bamboo were similarly employed . An See also:early specific allusion to the See also:quill pen occurs in the writings of St Isidore of See also:Seville (early See also:part of the 7th See also:century),' but there is no See also:reason to assume that it was not in use at a still more remote date . The quills still largely employed among Western communities as writing See also:instruments are obtained principally from the wings of the See also:goose (see FEATHER) . In 1809 See also:Joseph See also:Bramah devised and patented a See also:machine for cutting up the quill into See also:separate nibs by dividing the See also:barrel into three or even four parts, and cutting these transversely into " two, three, four and some into five lengths." Bramah's invention first familiarized the public with the See also:appearance and use of the nib slipped into a holder . In 1818 See also:Charles See also:Watt obtained a patent for See also:gilding and preparing quills and pens, which may be regarded as the precursor of the See also:gold pen . But a more distinct advance was effected in 1822, when J . I . See also:Hawkins and S .

Mordan patented the application of See also:

horn and See also:tortoise-See also:shell to the formation of pen-nibs, the points of which were rendered durable by small pieces of See also:diamond, See also:ruby or other very hard substance, or by lapping a small piece of thin See also:sheet gold over the end of the tortoise-shell . Metallic pens, though not unknown in classical times—a See also:bronze pen found at See also:Pompeii is in the See also:Naples Museum—were little used until the 19th century and did not See also:steel Pens. become See also:common till near the See also:middle of that century . It is recorded that a See also:Birmingham split-See also:ring manufacturer, See also:Samuel See also:Harrison, made a steel pen for Dr Joseph See also:Priestley in 1780 . Steel pens made and sold in See also:London by a certain See also:Wise in 1803 were in the See also:form of a See also:tube or barrel, the edges of which met to form the slit, while the sides were cut away as in the See also:case of an See also:ordinary quill . Their See also:price was about five shillings each, and as they were hard, stiff and unsatisfactory instruments they were not in See also:great demand . A metallic pen patented by 1" Instrumenta scribae calamus et penna; ex his enim verba paginis infiguntur; sed calamus arboris est, penna avis, cujus acumen dividitur in duo." See also:Bryan See also:Donkin in 18o8 was made of two separate parts, See also:flat or nearly so, with the flat sides placed opposite each other to form the slit, or alternatively of one piece, flat and not cylindrical as in the usual form, See also:bent to the proper See also:angle for insertion in the tube which constituted the holder . To See also:John See also:Mitchell probably belongs the See also:credit of introducing machine-made pens, about 1822, and See also:James See also:Perry is believed to have been the first maker of steel slip pens . In 1828 See also:Josiah See also:Mason, who had been associated with Samuel Harrison, in the manufacture of split rings, saw Perry's pens on salein Birmingham, and after examining them saw his way both to improve and to cheapen the See also:process of making them . He therefore put himself in communication with Perry, and the result was that he began to make barrel pens for him in 1828 and slip pens in 1829 . Perry, who did much to popularize the steel pen and bring it into See also:general use, in his patent of 183o sought to obtain greater flexibility by forming a central hole between the points and the shoulders and by cutting one or more lateral slits on each See also:side of the central slit; and Joseph See also:Gillot, in 1831 described an improvement which consisted in forming elongated points on the nibs of the pens . The metal used consists of rolled sheets of See also:cast steel of the finest quality made from See also:Swedish See also:charcoal See also:iron . These sheets, after being cut into strips of suitable width, annealed in a muffle-See also:furnace and pickled in a See also:bath of dilute sulphuric See also:acid to See also:free the See also:surface from oxidized See also:scale, are rolled between steel rollers till they are reduced to See also:ribbons of an even thickness, about -I- -s in .

From these ribbons the pen blanks are next punched out, and then, after being embossed with the name of the maker or other marks, are pierced with the central perforation and the side or See also:

shoulder slits by which flexibility is obtained . After another See also:annealing, the blanks, which up to this point are flat, are " raised " or rounded between See also:dies into the See also:familiar semi-cylindrical shape . The next process is to harden and See also:temper them by See also:heating them in iron boxes in a muffle-furnace, plunging them in oil, and then heating them over a See also:fire in a rotating cylindrical See also:vessel till their surfaces attain the dull See also:blue tint characteristic of See also:spring-steel See also:elasticity . Subsequently they are " scoured " in a bath of dilute acid, and polished in a revolving See also:cylinder . The grinding of the points with See also:emery follows, and then the central slit is cut by the aid of two very See also:fine-edged cutters . Finally the pens are again polished, are coloured by being heated over a fire in a revolving cylinder, and in some cases are coated with a See also:varnish of shellac dissolved in See also:alcohol . Birmingham was the first See also:home of the steel-pen See also:industry, and continues its See also:principal centre . The manufacture on a large scale was begun in the See also:United States about r86o at See also:Camden, N . J., where the Esterbrook Steel Pen Manufacturing See also:Company was incorporated in 1866 . Metals other than steel have frequently been suggested by inventors, those most commonly proposed being gold, See also:silver, See also:zinc, German silver, See also:aluminium and aluminium bronze .

Wollaston, it is recorded, had Gold pens. a gold pen composed of two thin strips of gold tipped with See also:rhodium, apparently made on the principle patented by Donkin in 1808, and See also:Lord See also:Byron used one in 181o . Gold being extremely resistant to corrosion, pens made of it are very durable, but the metal is too soft for the points, which See also:wear quickly unless protected by some harder material . For this purpose See also:iridium is widely employed, by fusing the gold See also:round it with a See also:blowpipe . Various devices have been adopted in See also:order to increase the See also:time for which a pen can be used without a fresh See also:supply of ink . These fall into two See also:main classes . In one, the form See also:Reservoir of the nib itself is modified, or some See also:attachment pens . is added, to enlarge the ink capacity; in the other, which is by far the more important, the holder of the pen is utilized as a cistern or reservoir from which ink is supplied to the nib . Pens of the second class, which have the further See also:advantage of being portable, are heard of under the name of " See also:fountain inkhorns " or " fountain pens " so far back as the beginning of the 18th century, but it was not till a See also:hundred years later that inventors applied themselves seriously to their construction . Joseph Bramah patented several plans; one was to employ a tube of silver or other metal so thin that it could be readily squeezed out of shape, the ink within it being thus forced out to the nib, and another was to See also:fit the tube with a See also:piston that could slide down the interior and thus eject ink . In modern fountain pens a feed See also:bar conveys, by capillary See also:action, a fresh supply of ink to replace that which has been See also:left on the See also:paper in the See also:act of writing, means being also provided by which See also:air can pass into the reservoir and fill the space left empty by the outflowing ink . In another form of reservoir pen, which is usually distinguished by the name stylograph, there is no nib, but the ink flows out through a See also:minute hole at the end of the holder, which terminates in a conical point . An iridium See also:needle, held in See also:place by a fine spring, projects slightly through the hole and normally keeps the See also:aperture closed; but when the pen is pressed on the paper, the needle is pushed back and allows a thin stream of ink to flow out .
