The anchor escapement was invented by clockmaker William Clement, [1] [2] [3] who popularized the anchor in his invention of the longcase or grandfather clock around 1680. Clement's invention was a substantial improvement on Robert Hooke's constant force escapement of 1671. [4] The oldest known anchor clock is Wadham College Clock, a tower ...
A grandfather clock (also a longcase clock, tall-case clock, grandfather's clock, hall clock or floor clock) is a tall, freestanding, weight-driven pendulum clock, with the pendulum held inside the tower or waist of the case. Clocks of this style are commonly 1.8–2.4 metres (6–8 feet) tall with an enclosed pendulum and weights, suspended by ...
The long narrow clocks built around these pendulums, first made by William Clement around 1680, who also claimed invention of the anchor escapement, [4] became known as grandfather clocks. The increased accuracy resulting from these developments caused the minute hand, previously rare, to be added to clock faces beginning around 1690. [10] [4]
The first known anchor escapement clock was built by the English clockmaker William Clement in 1671 for King's College, Cambridge, [131] now in the Science Museum, London. [132] The anchor escapement originated with Hooke, although it has been argued that it was invented by Clement, [133] or the English clockmaker Joseph Knibb. [132]
The seconds pendulum (also called the Royal pendulum), 0.994 m (39.1 in) long, in which each swing takes one second, became widely used in quality clocks. The long narrow clocks built around these pendulums, first made by William Clement around 1680, became known as grandfather clocks. The increased accuracy resulting from these developments ...
Johannes Sayler (1597–1668), German watchmaker, Ulm, rolling ball clock, turret clocks, table clocks. Nicolas Lemaindre (1598–1652), French clockmaker, Blois, clockmaker of the court. Jost Bodeker von Wartbergh, German vicar, Osnabrück. craft clock with a centrifugal pendulum (1578 to 1587).
The longcase clock (also known as the grandfather clock) was created to house the pendulum and works by the English clockmaker William Clement in 1670 or 1671. It was also at this time that clock cases began to be made of wood and clock faces to use enamel as well as hand-painted ceramics.
] The Temple of the Great Clockmaker, in the novel The Case Of The Dead Certainty by Kel Richards, is a temple which represents deism. The Clock Maker Theory and the watchmaker analogy describe by way of analogy religious, philosophical, and theological opinions about the existence of god(s) that have been expressed over the years.
