By description a pendulum is typically long thin rod that is designed out of metal or wood with a disc at the edge. The first pendulum clocks that were ever created had a disc that pulled down the pendulum rod with its weight as it moved from one side to another. The clock also had an escarpment gear that was responsible for the movement of a gear allowing for the pendulum to swing in the process there was creation of energy that reduced friction and gave the pendulum enough power to continue swinging.

As the inventions improved the pendulum clocks were later designed being powered by springs to finally batteries. This system of measuring time can be credited to Galileo who come up with a tool after studying its motion since 1582. However, Galileo only came up with the design for the pendulum clock but died before it was actually built. These types of clocks have the same mechanisms as the wooden wall clocks. After Galileo had designed the clocks it would be in 1656 when the Dutch astronomer and mathematician Christian Huygens would finally create the pendulum clock. And he is actually credited for the creation of the pendulum clock.
The pendulum clock created by Huygens measured time with an error of about one minute in a day, although this was improved through his later models whereby he was able to reduce the error to less the 10 seconds. Later on George Graham increased the accuracy with the reduction of the error to about one second per day in 1721. He was able to reduce the error by making some adjustment on the length of the pendulum rod’s length which was affected by temperature variations. The development of the pendulum clocks leads to the invention of other type of clocks such as the men’s wooden watches.
The accuracy of the pendulum clocks was later improved by W.H short and Siegmund Riefler even more. The Riefler’s clock utilized an escarpment that he had created in 1889. This clock became popular with astronomical observatories since it was accurate to about a hundredth of second every day. Later on the Shortt clock was introduced in 1921 that was run on a master principle and two pendulums and later become the clock of choice for most observatories. In the 1920’s the quartz technology and it began phasing out the pendulum and actually became the standard method of measuring time and for subsequent years. When the quartz clocks were invented people started collecting the pendulum clocks as the collector’s item as contemporary types and antique pieces as well.
There are various kinds of pendulum clocks that might be collected as collector’s pieces which include mantel clock, cuckoo clock and grandfather. The grandfather and cuckoo clocks have the pendulum swinging typically about once every two seconds and twice every second respectively. Along with the desired clocks individuals can buy barometer online which can be used for the intended purposes. However, for those that love to collect art pieces they can buy the pendulum clocks.
