There is a fusee in the earliest surviving spring-driven clock, a chamber clock made for Philip the Good in c. 1430. [109] Leonardo da Vinci , who produced the earliest known drawings of a pendulum in 1493–1494, [ 110 ] illustrated a fusee in c. 1500, a quarter of a century after the coiled spring first appeared.
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. In 1670, William Clement created the anchor escapement ...
Early time clock, made by National Time Recorder Co. Ltd. of Blackfriars, London at Wookey Hole Caves museum A Bundy clock used by Birmingham Corporation Transport. An early and influential time clock, sometimes described as the first, was invented on November 20, 1888, by Willard Le Grand Bundy, [4] a jeweler in Auburn, New York.
Sometimes inventions are invented by several inventors around the same time, or may be invented in an impractical form many years before another inventor improves the invention into a more practical form. Where there is ambiguity, the date of the first known working version of the invention is used here.
The most accurate pendulum clock was the Shortt-Synchronome clock, a complicated electromechanical clock with two pendulums developed in 1923 by W.H. Shortt and Frank Hope-Jones, which was accurate to better than one second per year. A slave pendulum in a separate clock was linked by an electric circuit and electromagnets to a master pendulum ...
The torsion pendulum was invented by Robert Leslie in 1793. [3] The torsion pendulum clock was first invented and patented by American Aaron Crane in 1841. [4] He made clocks that would run up to one year on a winding. He also made precision astronomical regulator clocks based on the torsion pendulum, but only four were sold.
The discovery, they say, may be the most significant in a series of archaeological finds made at the mouth of the Miami River in the past 25 years that include the Miami Circle National Historic ...
Distinctively for Willard's workshop, above the clock's top fretwork, three pedestals were, on which two spherical finials and a large bird figure were mounted. In addition, like Aaron, Simon built a glass dial door, whose top had a half arch shape. Onto the dial, Boston painters painted different motifs. Also, with few extra mechanism, amusing ...
