Banjo Clock
The banjo clock, or banjo timepiece, is an American wall clock with a banjo-shaped case. It was invented by Simon Willard, originally of Grafton, Massachusetts, later of Roxbury, Massachusetts, and patented in 1802. The banjo clock normally lacks a striking mechanism and indicates time only by its hands and dial, for which reason some horologists may insist upon calling it a timepiece rather than a true clock. In popular usage though, no such distinction is made. The banjo style of wooden case usually features a round opening for a painted dial, a long-waisted throat, and a rectangular pendulum box with hinged door. Both the throat and door are ornamented with reverse-painted ('' verre églomisé'') glass panels, and the case is usually flanked by curved and pierced brass frets. A finial mounted atop the case usually takes the form of a cast-brass eagle Eagle is the common name for many large birds of prey of the family Accipitridae. Eagles belong to several groups of ge ...

Banjo Clock 001
The banjo is a stringed instrument with a thin membrane stretched over a frame or cavity to form a resonator. The membrane is typically circular, and usually made of plastic, or occasionally animal skin. Early forms of the instrument were fashioned by African Americans in the United States. The banjo is frequently associated with folk, bluegrass and country music, and has also been used in some rock, pop and hip-hop. Several rock bands, such as the Eagles, Led Zeppelin, and the Grateful Dead, have used the five-string banjo in some of their songs. Historically, the banjo occupied a central place in Black American traditional music and the folk culture of rural whites before entering the mainstream via the minstrel shows of the 19th century. Along with the fiddle, the banjo is a mainstay of American styles of music, such as bluegrass and old-time music. It is also very frequently used in Dixieland jazz, as well as in Caribbean genres like biguine, calypso and mento. Hist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pendulum
A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position. When released, the restoring force acting on the pendulum's mass causes it to oscillate about the equilibrium position, swinging back and forth. The time for one complete cycle, a left swing and a right swing, is called the period. The period depends on the length of the pendulum and also to a slight degree on the amplitude, the width of the pendulum's swing. From the first scientific investigations of the pendulum around 1602 by Galileo Galilei, the regular motion of pendulums was used for timekeeping and was the world's most accurate timekeeping technology until the 1930s. The pendulum clock invented by Christiaan Huygens in 1658 became the world's standard timekeeper, used in homes and offices for 270 years, and ac ...

Lighthouse Clock
A lighthouse clock is a type of mantel clock manufactured in the U. S. from 1818 through 1830s by the American clockmaker Simon Willard, having the dial and works exposed beneath a glass dome on a tapered, cylindrical body. They were also made by Simon Willard & Son, a partnership between the clockmaker and his son Simon Willard Jr. created in 1823. The father and son were in partnership for five years and in 1828, Simon Willard, Jr. established his own shop in Boston. History Lighthouse clocks are regarded as the first alarm clocks produced in America, although a significant number of the later clocks of this type were crafted without alarms.Bob Jackman, ''The Lighthouse Clocks of Simon Willard'' (2002): in Antiques and the Arts Online [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Krause Publications
Krause Publications is an American publisher of hobby magazines and books. Originally a company founded and based in Iola, Wisconsin, they relocated to Stevens Point, Wisconsin, in April 2018. The company was started by Chester L. Krause (19232016) upon the publication in October 1952 of the first issue of '' Numismatic News''. In the coin collecting community the company is best known for its ''Standard Catalog of World Coins'', a series of coin catalogs commonly referred to as ''Krause-Mishler'' catalogs or simply ''Krause'' catalogs; they provide information, pricing, and Krause-Mishler (KM) numbers referring to coin rarity and value. Krause-Mishler (named for Krause and longtime employee Clifford Mishler) numbers are the most common way of assigning values to coins. The first edition was published in 1972. In addition, they established the Coin of the Year Award, first issued in 1984, for excellence in coinage design. In the paper money collecting community the company is ...

Acorn
The acorn, or oaknut, is the nut of the oaks and their close relatives (genera ''Quercus'' and '' Lithocarpus'', in the family Fagaceae). It usually contains one seed (occasionally two seeds), enclosed in a tough, leathery shell, and borne in a cup-shaped cupule. Acorns are long and on the fat side. Acorns take between 5 and 24 months (depending on the species) to mature; see the list of ''Quercus'' species for details of oak classification, in which acorn morphology and phenology are important factors. Etymology The word ''acorn'' (earlier ''akerne'', and ''acharn'') is related to the Gothic name ''akran'', which had the sense of "fruit of the unenclosed land". The word was applied to the most important forest produce, that of the oak. Chaucer spoke of "achornes of okes" in the 14th century. By degrees, popular etymology connected the word both with "corn" and "oak-horn", and the spelling changed accordingly. The current spelling (emerged 15c.-16c.), derives from asso ...

Gilding
Gilding is a decorative technique for applying a very thin coating of gold over solid surfaces such as metal (most common), wood, porcelain, or stone. A gilded object is also described as "gilt". Where metal is gilded, the metal below was traditionally silver in the West, to make silver-gilt (or ''vermeil'') objects, but gilt-bronze is commonly used in China, and also called ormolu if it is Western. Methods of gilding include hand application and gluing, typically of gold leaf, chemical gilding, and electroplating, the last also called gold plating. Parcel-gilt (partial gilt) objects are only gilded over part of their surfaces. This may mean that all of the inside, and none of the outside, of a chalice or similar vessel is gilded, or that patterns or images are made up by using a combination of gilt and ungilted areas. Gilding gives an object a gold appearance at a fraction of the cost of creating a solid gold object. In addition, a solid gold piece would often be too soft or ...

Eagle
Eagle is the common name for many large birds of prey of the family Accipitridae. Eagles belong to several groups of genera, some of which are closely related. Most of the 68 species of eagle are from Eurasia and Africa. Outside this area, just 14 species can be found—2 in North America, 9 in Central and South America, and 3 in Australia. Eagles are not a natural group but denote essentially any kind of bird of prey large enough to hunt sizeable (about 50 cm long or more overall) vertebrates. Description Eagles are large, powerfully-built birds of prey, with heavy heads and beaks. Even the smallest eagles, such as the booted eagle (''Aquila pennata''), which is comparable in size to a common buzzard (''Buteo buteo'') or red-tailed hawk (''B. jamaicensis''), have relatively longer and more evenly broad wings, and more direct, faster flight – despite the reduced size of aerodynamic feathers. Most eagles are larger than any other raptors apart from some vultures. The smalles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Finial
A finial (from '' la, finis'', end) or hip-knob is an element marking the top or end of some object, often formed to be a decorative feature. In architecture, it is a small decorative device, employed to emphasize the Apex (geometry), apex of a dome, spire, tower, roof, or gable or any of various distinctive ornaments at the top, end, or corner of a building or structure. A finial is typically carved in stone. Where there are several such elements they may be called pinnacles. The very top of a finial can be a floral or foliated element called a bouquet. Smaller finials in materials such as metal or wood are used as a decorative ornament on the tops or ends of poles or rods such as tent-poles or curtain rods or any object such as a piece of furniture. These are frequently seen on top of bed posts or clocks. Decorative finials are also commonly used to fasten lampshades, and as an ornamental element at the end of the handles of souvenir spoons.

Brass
Brass is an alloy of copper (Cu) and zinc (Zn), in proportions which can be varied to achieve different mechanical, electrical, and chemical properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. Brass is similar to bronze, another copper alloy, that uses tin instead of zinc. Both bronze and brass may include small proportions of a range of other elements including arsenic (As), lead (Pb), phosphorus (P), aluminium (Al), manganese (Mn), and silicon (Si). Historically, the distinction between the two alloys has been less consistent and clear, and modern practice in museums and archaeology increasingly avoids both terms for historical objects in favor of the more general "copper alloy". Brass has long been a popular material for decoration due to its bright, gold-like appearance; being used for drawer pulls and doorknobs. It has also been widely used to make utensils because of its low melting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Verre églomisé
''Verre églomisé'' is a French term referring to the process of applying both a design and gilding onto the rear face of glass to produce a mirror finish. The name is derived from the 18th-century French decorator and art-dealer Jean-Baptiste Glomy (1711–1786), who was responsible for its revival. Glomy's technique was a relatively simple one of applying decorative designs in a combination of plain colour and gilding, usually to glass picture frames. However, over time it has come to be used to describe nearly any process involving back-painted and gilded glass, however elaborate. The technique of back-painting glass actually dates back to pre-Roman eras. One of the key historical periods of the art was in Italy during the 13th to 16th centuries. Small panels of glass with designs formed by engraved gilding were applied to reliquaries and portable altars. The method used is described by Cennino Cennini. Other practitioners include Jonas Zeuner and Hans Jakob Sprungli (15 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rectangular
In Euclidean geometry, Euclidean plane geometry, a rectangle is a quadrilateral with four right angles. It can also be defined as: an equiangular quadrilateral, since equiangular means that all of its angles are equal (360°/4 = 90°); or a parallelogram containing a right angle. A rectangle with four sides of equal length is a ''square''. The term "wikt:oblong, oblong" is occasionally used to refer to a non-square rectangle. A rectangle with Vertex (geometry), vertices ''ABCD'' would be denoted as . The word rectangle comes from the Latin ''rectangulus'', which is a combination of ''rectus'' (as an adjective, right, proper) and ''angulus'' (angle). A #Crossed rectangles, crossed rectangle is a crossed (self-intersecting) quadrilateral which consists of two opposite sides of a rectangle along with the two diagonals (therefore only two sides are parallel). It is a special case of an antiparallelogram, and its angles are not right angles and not all equal, though opposite angles ...
