Rose Engine Lathe
A rose engine lathe is a specialized kind of geometric lathe. The head stock rocks back and forth with a rocking motion and/or slides along the spindle axis in a pumping motion. A rosette or cam-like pattern mounted on the spindle is controlled by moving against a cam follower(s) while the lathe spindle rotates. Rose engine work can make flower patterns, as well as convoluted, symmetrical, multi-lobed geometric patterns. The patterns it produces are similar to that of a Spirograph, in metal. No other ornamental lathe can produce these "rose" patterns. The decoration produced by a rose engine lathe is called guilloche. It sometimes confused with "jewel finishes" or engine turning, a much cheaper process of making swirly marks in metal by a rotating abrasive peg or pad, which is repeatedly applied to the surface to make a pattern of overlapping circles. Jewel finishes used to be common on stereo faceplates and automobile interiors. The patterns of United Kingdom's first postage s ...

Penny Black
The Penny Black was the world's first adhesive postage stamp used in a public postal system. It was first issued in the United Kingdom (referred to in philatelic circles as Great Britain), on 1 May 1840, but was not valid for use until 6 May. The stamp features a profile of Queen Victoria. In 1837, British postal rates were high, complex and anomalous. To simplify matters, Sir Rowland Hill proposed an adhesive stamp to indicate pre-payment of postage. At the time it was normal for the recipient to pay postage on delivery, charged by the sheet and on distance travelled. By contrast, the Penny Black allowed letters of up to to be delivered at a flat rate of one penny, regardless of distance. Treasury competition On 13 February 1837, Sir Rowland Hill proposed to a government enquiry both the idea of a pre-paid stamp and a pre-paid envelope, a separate sheet folded to form an enclosure for carrying letters. Hill was given a two-year contract to run the new system, and tog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geometric Lathe
A geometric lathe was used for making ornamental patterns on the plates used in printing bank notes and postage stamps. It is sometimes called a guilloché lathe. It was developed early in the nineteenth century when efforts were introduced to combat forgery, and is an adaptation of an ornamental turning lathe. The lathe was able to generate intersecting and interlacing patterns of fine lines in various shapes, which were almost impossible to forge by hand-engraving. They were used by many national mints.

Spirograph
Spirograph is a geometric drawing device that produces mathematical roulette curves of the variety technically known as hypotrochoids and epitrochoids. The well-known toy version was developed by British engineer Denys Fisher and first sold in 1965. The name has been a registered trademark of Hasbro Inc. since 1998 following purchase of the company that had acquired the Denys Fisher company. The Spirograph brand was relaunched worldwide in 2013, with its original product configurations, by Kahootz Toys. History In 1827, Greek-born English architect and engineer Peter Hubert Desvignes developed and advertised a "Speiragraph", a device to create elaborate spiral drawings. A man named J. Jopling soon claimed to have previously invented similar methods. When working in Vienna between 1845 and 1848, Desvignes constructed a version of the machine that would help prevent banknote forgeries, as any of the nearly endless variations of roulette patterns that it could produce were ext ...

Engine Turning
Engine turning, also known as jewelling, is a fine geometric pattern turned onto metal as a finish. Aluminium is often the metal chosen to inscribe, but any appropriate surface can be finely machined to produce intricate repetitive patterns that offer reflective interest and fine detail. Uses Aircraft ''Perlée''-style engine turning was used on the sheetmetal panels of the engine cowling (nose) of Charles Lindbergh's aircraft, the ''Spirit of St. Louis''. The sheet metal parts of the World War I Fokker Eindecker fighter aircraft series, especially around the engine cowl and associated sheetmetal, are noted for having a "dragged" form of engine turning entirely covering them. The tool creating the "swirls" was repeatedly moved along a short irregular path each time while pressed against the metal, to create the intricate appearance that was characteristic of the aircraft's sheet-metal parts. It is partly surmised to have been a mechanical method to "clad" a duralumin-alloy s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stanley Gibbons
The Stanley Gibbons Group plc is a company quoted on the London Stock Exchange specialising in the retailing of collectable postage stamps and similar products. The group is incorporated in London. The company is a major stamp dealer and philatelic publisher. The company's philatelic subsidiary, Stanley Gibbons Limited, has a royal warrant of appointment from Queen Elizabeth II. History The company has a long corporate history, having started as a sole trader business owned by Edward Stanley Gibbons in 1856 and now being a quoted company with a number of subsidiaries. Before 1900 The business started when, employed as an assistant in his father's pharmacy shop in Plymouth, Gibbons set up a counter selling stamps. In 1863 he was fortunate enough to purchase from two sailors a sackful of rare Cape of Good Hope triangular stamps. In 1874 Gibbons moved to a house near Clapham Common in South London and in 1876 he moved again to Gower Street in Bloomsbury near the British Mu ...

Guilloché
Guilloché (; or guilloche) is a decorative technique in which a very precise, intricate and repetitive pattern is mechanically engraved into an underlying material via engine turning, which uses a machine of the same name, also called a rose engine lathe. This mechanical technique improved on more time-consuming designs achieved by hand and allowed for greater delicacy, precision, and closeness of line, as well as greater speed. The term ''guilloche'' is also used more generally for repetitive architectural patterns of intersecting or overlapping spirals or other shapes, as used in the Ancient Near East, classical Greece and Rome and neo-classical architecture, and Early Medieval interlace decoration in Anglo-Saxon art and elsewhere. Medieval Cosmatesque stone inlay designs with two ribbons winding around a series of regular central points are very often called guilloche. These central points are often blank, but may contain a figure, such as a rose. These senses are a ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fabergé Egg
A Fabergé egg (russian: link=no, яйцо Фаберже́, translit=yaytso Faberzhe) is a jewelled egg created by the jewellery firm House of Fabergé, in Saint Petersburg, Russia. As many as 69 were created, of which 57 survive today. Virtually all were manufactured under the supervision of Peter Carl Fabergé between 1885 and 1917. The most famous are his 52 "Imperial" eggs, 46 of which survive, made for the Russian Tsars Alexander III and Nicholas II as Easter gifts for their wives and mothers. Fabergé eggs are worth millions of dollars and have become symbols of opulence. History The House of Fabergé was founded by Gustav Fabergé in 1842 in St. Petersburg, Russia. The Fabergé egg was a later addition to the product line by his son, Peter Carl Fabergé. Prior to 1885, Tsar Alexander III gave his wife Empress Maria Feodorovna jeweled Easter eggs. For Easter in 1883, before his coronation, Alexander III and Maria Feodorovna were given eggs, one of which contained a sil ...
