Rolling Ball Clock
A rolling ball clock is a clock which displays time by means of balls and rails. History The rolling ball clock was invented by Harley Mayenschein in the 1970s. He patented the design and founded Idle Tyme Corporation in 1978, which manufactured these clocks from solid hardwoods. Later, a license on the patent was sold to Arrow Handicraft. In the 1970s and early 1980s, Mattel also made them under license. The following excerpts from a letter written by Patrice Gunville, the daughter of Harley Mayenschein, give some detail of the history of the clock:For an even more detailed history of the clock and its inventor, visit the clock's new home page at http://www.idle-tyme.com These clocks are once again being produced in a small shop run by Harley's son Joe. Joe was the primary builder of the clocks when the shop was in full production 25 years ago. The very first original design (before patent) was simple × inch strips of wood which the balls would roll on, much like the desi ...

Clock
A clock or a timepiece is a device used to measure and indicate time. The clock is one of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units such as the day, the lunar month and the year. Devices operating on several physical processes have been used over the millennia. Some predecessors to the modern clock may be considered as "clocks" that are based on movement in nature: A sundial shows the time by displaying the position of a shadow on a flat surface. There is a range of duration timers, a well-known example being the hourglass. Water clocks, along with the sundials, are possibly the oldest time-measuring instruments. A major advance occurred with the invention of the verge escapement, which made possible the first mechanical clocks around 1300 in Europe, which kept time with oscillating timekeepers like balance wheels., pp. 103–104., p. 31. Traditionally, in horology, the term ''clock'' was used for a stri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time
Time is the continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future. It is a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience. Time is often referred to as a fourth dimension, along with three spatial dimensions. Time has long been an important subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without circularity has consistently eluded scholars. Nevertheless, diverse fields such as business, industry, sports, the sciences, and the performing arts all incorporate some notion of time into their respective measuring systems. 108 pages. Time in physics is operationally defined as "what a clock reads". The physical nature of time is addre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Washington Post
''The Washington Post'' (also known as the ''Post'' and, informally, ''WaPo'') is an American daily newspaper published in Washington, D.C. It is the most widely circulated newspaper within the Washington metropolitan area and has a large national audience. Daily broadsheet editions are printed for D.C., Maryland, and Virginia. The ''Post'' was founded in 1877. In its early years, it went through several owners and struggled both financially and editorially. Financier Eugene Meyer purchased it out of bankruptcy in 1933 and revived its health and reputation, work continued by his successors Katharine and Phil Graham (Meyer's daughter and son-in-law), who bought out several rival publications. The ''Post'' 1971 printing of the Pentagon Papers helped spur opposition to the Vietnam War. Subsequently, in the best-known episode in the newspaper's history, reporters Bob Woodward and Carl Bernstein led the American press's investigation into what became known as the Watergate scandal ...

Arrow Handicraft
An arrow is a fin-stabilized projectile launched by a bow. A typical arrow usually consists of a long, stiff, straight shaft with a weighty (and usually sharp and pointed) arrowhead attached to the front end, multiple fin-like stabilizers called fletchings mounted near the rear, and a slot at the rear end called a nock for engaging the bowstring. A container or bag carrying additional arrows for convenient reloading is called a quiver. The use of bows and arrows by humans predates recorded history and is common to most cultures. A craftsman who makes arrows is a fletcher, and one that makes arrowheads is an arrowsmith.Paterson ''Encyclopaedia of Archery'' p. 56 History The oldest evidence of likely arrowheads, dating to c. 64,000 years ago, were found in Sibudu Cave, current South Africa.Backwell L, d'Errico F, Wadley L.(2008).

Coin Clock
A coin is a small, flat (usually depending on the country or value), round piece of metal or plastic used primarily as a medium of exchange or legal tender. They are standardized in weight, and produced in large quantities at a mint in order to facilitate trade. They are most often issued by a government. Coins often have images, numerals, or text on them. ''Obverse'' and its opposite, ''reverse'', refer to the two flat faces of coins and medals. In this usage, ''obverse'' means the front face of the object and ''reverse'' means the back face. The obverse of a coin is commonly called ''heads'', because it often depicts the head of a prominent person, and the reverse ''tails''. Coins are usually made of metal or an alloy, or sometimes of man-made materials. They are usually disc shaped. Coins, made of valuable metal, are stored in large quantities as bullion coins. Other coins are used as money in everyday transactions, circulating alongside banknotes. Usually the highest va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Congreve Clock
A Congreve clock (also known as Congreve's Rolling Ball Clock or Oscillating Path Rolling Ball Clock) is a type of clock that uses a ball rolling along a zigzag track rather than a pendulum to regulate the time. It was invented by William Congreve (inventor), Sir William Congreve in 1808. The ball takes between 15 seconds and one minute to run down the zigzag track, where it trips the escapement which in turn reverses the tilt of the tray and at the same time causes the hands of the clock to move forward. Thus the angle of the plate reverses and the clock hands move forward between one and four times every minute. On versions of the clock with a dial to indicate seconds, the second hand jumps forward either 15 or 30 seconds on each oscillation depending on the length of the track. Congreve appears to have been unaware that rolling ball clocks had been invented earlier by both Nicolas Grollier de Servière and Johann Sayller. Congreve's version differed from Grollier's rolling ball ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
