Displayed at the center of Su-Sung's mechanical clock was a large, bronze celestial globe that measured 4.5 feet in diameter. The weight of the buckets exerted enough force to activate all sorts of wonderful displays.
#When were clocks invented full
When a full bucket was heavy enough to trip a mechanism, it fell forward and the bucket behind it moved into place under the water spout. Buckets around the rim of the water wheel were filled, one at a time, by a steady flow of water. Su-Sung's huge clock stood 40 feet high and was powered by a special water wheel. Each candle completely burned away in four hours, each mark represented 20 minutes.įact 9: Who invented the Clock? The Hourglass: The Hourglass was another device for measuring time, that consisted of two glass chambers, connected by a narrow passage, that contained a quantity of sand, that slowly trickled from the upper chamber to the lower chamber in a fixed amount of time, usually one hour.įact 10: Who invented the Clock? Mechanical Clocks: The invention of the first mechanical clock is credited to the Chinese scientist and inventor Su Sung (1020 - 1101 AD) in 1092. Uniform sized candles, marked into 12 sections each of one inch, were placed in protective cases. Water clocks were first used by the Ancient Egyptians, Greeks and the Mesopotamians as an alternative to clocks dependent on sunlight.įact 8: Who invented the Clock? Candle Clocks: The earliest reference to the use of candle clock occurs in a Chinese poem by You Jiangu (520 CE) but candle clocks were found in many other countries in the Ancient World. The Timestick was turned to the Sun so that the shadow falls directly down the scale.įact 7: Who invented the Clock? Water Clocks: The Water clock, also known by its Greek name clepsydra, used the flow of water with the change in water level to measure time. The sundial was believed to have been independently developed by the Ancient Egyptians and the Mesopotamians c.1500BC.įact 6: Who invented the Clock? The Timestick: The Shepherd's Timestick worked on the same principles as sundials, based on the relative amount of daylight during the different months of the year. The shadow is cast on the surface of the sundial that is marked to show hours, or fractions of hours, of the day.
#When were clocks invented portable
The Ancient Egyptians also went on to invent a smaller shadow clock, in the shape of a small notched rod, the first portable timepiece ever made.įact 5: Who invented the Clock? The Sundial: The Sundial used the shadow of the sun to indicate the time of day. The Obelisk symbolized the sun god Ra and also used as shadow clocks to track the movement of the sun throughout the day to keep track of time. Unlike a watch it is not adapted to be carried on the person.įact 1: Who invented the Clock? The pendulum Clock was invented by Christiaan Huygens in 1656 during the Renaissance era of inventions (1350 to 1700).įact 2: Who invented the Clock? The word clock derives from from Medieval Latin word 'clocca', meaning "bell".įact 3: Who invented the Clock? Prior to the invention of the pendulum Clock in 1656, there was a long history of timekeeping devices including shadow clocks, the water clock, the candle clock, the timestick, the hourglass and the sundial.įact 4: Who invented the Clock? Shadow Clocks: The monumental stone column Obelisks were set in pairs, at the entrances of temples and are a famous symbol of the Ancient Egyptians. Its internal mechanism or 'works' are moved by a weight or a spring, and often features the stroke of a hammer on a bell to tell the hour. This article provides a history timeline of all other timekeeping devices including Shadow Clocks, Sundials, Timesticks, Water Clocks, Candle Clocks, the Hourglass, Mechanical Clocks that led to the invention of Pendulum Clocks and beyond.ĭefinition of the Clock: The Clock is defined as a mechanical or electrical machine or device for measuring time, indicating the hour and other divisions by means of hands moving on a round dial plate or by displayed figures. When was the pendulum Clock invented? Christiaan Huygens invented the pendulum Clock in 1656, during the Renaissance period of inventions (1350 to 1700). Christiaan Huygens is not only famous as the Dutch inventor of the Clock but also as a mathematician, scientist, astronomer and diplomat. Who invented the Clock? The name of the person credited with inventing the pendulum Clock is Christiaan Huygens (1629 - 1695).
