Salisbury Cathedral clock, restored. The Salisbury Cathedral clock is a large iron-framed tower clock without a dial, in Salisbury Cathedral, England.Thought to date from about 1386, it is a well-preserved example of the earliest type of mechanical clock, called verge and foliot clocks, and is said to be the oldest working clock in the world, [1] although similar claims are made for other clocks.
The clock is one of the group of famous 14th– to 16th–century astronomical clocks to be found in the West of England. The surviving mechanism, dated to between 1386 and 1392, was replaced in the 19th century, and was eventually moved to the Science Museum in London, where it continues to operate. [ 1 ]
Benjamin Ward; London (1799–1808) Eardley Norton, a most highly esteemed member of the Clockmakers' Company, was working between 1762 and 1794. There are clocks by him in the Royal Collection and many museums worldwide. Norton made an astronomical clock for George III which still stands in Buckingham Palace.
Considering that sundial time varies +- 15 minutes throughout the year, the Cotehele clock was a perfect instrument for measuring time in the 15th and 16th century. If run 24 hours a day (the strike can be turned off at night), it only needed adjusting every couple of days at noon with the help of a sundial whenever the sun was out.
The clock was then moved to the Rochester Airport - after a time there it was put in storage. Now it is being renovated and will soon be displayed at Tower 280 in downtown Rochester. The oldest continuously running clock in the United States is located in Winnsboro, South Carolina, and dates all the way back to 1837.
The company claim to be the oldest clock manufacturer in the world, originally established in 1690, [1] and have been part of the Smith of Derby Group since 1965. [2] The claim is challenged by another English firm of clockmakers , Thwaites & Reed , who claim to have been in continuous manufacture since before 1740, with antecedents to 1610.
The gate clock distributed the time publicly; another time signal of the observatory was the time ball, since 1833. The time ball only signalled 1.00pm (13:00), but could be seen from afar. Eventually the idea of distributing time signals via wires led to more and more electrical distribution of time signals by this method.
Clock from Thwaites & Reed, 1817, now in Hessenpark, Germany. Thwaites & Reed has been in continuous manufacture since its foundation and claims to be the oldest clock manufacturing company in the world. Geoffrey Buggins MBE, the last of the original family clockmakers, saw drawings of Thwaites clocks dating back to 1610. [1]
