Telechron
Telechron is the name of a U.S. company that manufactured electric clocks between 1912 and 1992. "Telechron" is derived from the Greek word''tele'' meaning "far off," an''chronos'' "time," thus referring to the transmission of time over long distances. Founded by Henry Ellis Warren, Telechron introduced the synchronous electric clock, which keeps time by the oscillations of the alternating current electricity that powers it from the electric power grid. Telechron had its heyday between 1925 and 1955, when it sold millions of electric clocks to American consumers. Henry Warren: the Synchronous Motor and the Master Clock Henry E. Warren established the company in 1912 in Ashland, Massachusetts. Initially, it was called "The Warren Clock Company," producing battery-powered clocks. These proved unreliable, however, since batteries weakened quickly, which resulted in inaccurate time-keeping. Warren saw electric motors as the solution to this problem. In 1915, he invented a self-star ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ashland, Massachusetts
Ashland is a town in Middlesex County, Massachusetts, United States. It is part of the MetroWest region. The population was 18,832 at the 2020 United States Census. History The area now known as Ashland was settled in the early 18th century and inhabited prior to that by the Megunko Native Americans, to which Megunko Hill owes its name. Previously known as "Unionville", Ashland was incorporated in 1846, bearing the name of statesman Henry Clay's Kentucky estate. It is considerably younger than many of the surrounding towns, as Ashland's territory was taken in near-equal parts from the previously established towns of Hopkinton, Holliston (previously of colonial era Sherborn's territory), and Framingham. The construction of the Boston & Worcester Railroad, later the Boston & Albany, in the 1830s was key to the early development of the town. Decades later, two other rail lines opened stations in Ashland. Along with the Sudbury River, the railroad helped to attract numerous mills ...

Synchronous Electric Clock
An electric clock is a clock that is powered by electricity, as opposed to a mechanical clock which is powered by a hanging weight or a mainspring. The term is often applied to the electrically powered mechanical clocks that were used before quartz clocks were introduced in the 1980s. The first experimental electric clocks were constructed around the 1840s, but they were not widely manufactured until mains electric power became available in the 1890s. In the 1930s, the synchronous electric clock replaced mechanical clocks as the most widely used type of clock. Types Electric clocks can operate by several different types of mechanism: *''Electromechanical clocks'' have a traditional mechanical movement, which keeps time with an oscillating pendulum or balance wheel powered through a gear train by a mainspring, but use electricity to rewind the mainspring with an electric motor or electromagnet. This mechanism is found mostly in antique clocks. *''Electric remontoire clocks'' hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electric Time Company
Electric Time Company, founded in 1928, is a manufacturer of tower and street clocks marketed worldwide. History Electric Time Company was founded in 1928 and incorporated in the state of Massachusetts in 1932. It was founded by a salesman for the Self Winding Clock Company and Telechron of Ashland, Massachusetts. Originally part of Telechron it progressed from an office in Boston, Massachusetts to manufacturing facilities in Wellesley, Massachusetts; South Natick, Massachusetts; and, currently, a manufacturing facility in Medfield, Massachusetts. Electric Time produces approximately 1000 clocks annually and is the largest maker of custom outdoor clocks in the United States. Electric Time produces tower clocks, post clocks, and bracket clocks. Electric Time has many clock installations throughout the world, ranging from Brazil to Turkey to Europe. Some notable installations are Wrigley Field, Tiffany & Co, Disneyworld, Disneyland and the Great American Ball Park. Media Ele ...

Clock Manufacturing Companies Of The United States
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 striki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Synchronous Motor
A synchronous electric motor is an AC electric motor in which, at steady state, the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integral number of AC cycles. Synchronous motors contain multiphase AC electromagnets on the stator of the motor that create a magnetic field which rotates in time with the oscillations of the line current. The rotor with permanent magnets or electromagnets turns in step with the stator field at the same rate and as a result, provides the second synchronized rotating magnet field of any AC motor. A synchronous motor is termed ''doubly fed'' if it is supplied with independently excited multiphase AC electromagnets on both the rotor and stator. The synchronous motor and the induction motor are the most widely used types of AC motors. The difference between the two types is that the synchronous motor rotates at a rate locked to the line frequency since it does not rely on ...

Art Deco
Art Deco, short for the French ''Arts Décoratifs'', and sometimes just called Deco, is a style of visual arts, architecture, and product design, that first appeared in France in the 1910s (just before World War I), and flourished in the United States and Europe during the 1920s and 1930s. Through styling and design of the exterior and interior of anything from large structures to small objects, including how people look (clothing, fashion and jewelry), Art Deco has influenced bridges, buildings (from skyscrapers to cinemas), ships, ocean liners, trains, cars, trucks, buses, furniture, and everyday objects like radios and vacuum cleaners. It got its name after the 1925 Exposition internationale des arts décoratifs et industriels modernes (International Exhibition of Modern Decorative and Industrial Arts) held in Paris. Art Deco combined modern styles with fine craftsmanship and rich materials. During its heyday, it represented luxury, glamour, exuberance, and faith in socia ...

Quartz Clock
Quartz clocks and quartz watches are timepieces that use an electronic oscillator regulated by a quartz crystal to keep time. This crystal oscillator creates a signal with very precise frequency, so that quartz clocks and watches are at least an order of magnitude more accurate than mechanical clocks. Generally, some form of digital logic counts the cycles of this signal and provides a numerical time display, usually in units of hours, minutes, and seconds. Since the 1980s, when the advent of solid-state digital electronics allowed them to be made compact and inexpensive, quartz timekeepers have become the world's most widely used timekeeping technology, used in most clocks and watches as well as computers and other appliances that keep time. Explanation Chemically, quartz is a specific form of a compound called silicon dioxide. Many materials can be formed into plates that will resonate. However, quartz is also a piezoelectric material: that is, when a quartz crystal is su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
