French rococo bracket clocks |
"The clock is one of the oldest human inventions, meeting the need to consistently measure intervals of time shorter than the
natural units, the day, the lunar month, and the year. Such measurement requires devices. Devices operating on several different
physical processes have been used over the millennia, culminating in the clocks of today.
The first mechanical alarm clock was invented by the Ottoman engineer Taqi al-Din. He described the alarm clock in his book, The Brightest Stars for the Construction of Mechanical Clocks (Al-Kawâkib al-durriyya fî wadh' al-bankâmat al-dawriyya), published in 1556-1559.

at a specified time, achieved by placing a peg on the dial wheel.
At the requested time, the peg activated a ringing device. In the same treatise, he described a mechanical astronomical clock called the "observational clock", which was the first to measure time in minutes. He made use of his mathematical knowledge to design three dials which showed the hours, degrees and minutes. He later improved the design of his observational clock to measure time in seconds in an astronomical treatise written at his Istanbul observatory of al-Din (1577-1580). He described his observational clock as "a mechanical clock with three dials which show the hours, the minutes, and the seconds." This was an important innovation in 16th-century practical astronomy, as previous clocks were not accurate enough to be used for astronomical purposes. He further |

improved the observational clock, using only one dial to represent the hours, minutes and seconds,
describing it as "a mechanical clock with a dial showing the hours, minutes and seconds and we divided every minute into
five seconds."
On November 17, 1797, Eli Terry received his first patent for a clock. Terry is known as the founder of the American clock-making industry.

Alexander Bain, Scottish clockmaker, patented the electric clock in 1840. The electric clock's mainspring is wound either with an electric motor or with an electro-magnet and armature. In 1841, he first patented the electromagnetic pendulum. "This information found: Wikipedia Encylopedia
Dear Antique Clock Fans,
I am writing to you in behalf of your Heavenly Father. He is seeking you like a lost sheep. You remember the Bible story? It is about a shepherd who has 100 sheep. But when he brings the sheep home one night, one is missing. He then leaves the 99 sheep and goes out into the wilderness until he finds that lost sheep.In this parable the shepherd goes out to search for the one lost sheep-the very least that can be numbered. So if there had been but one lost soul, Christ would have died for that one. To read more click Lost Sheep
