History of the pendulum clock a pendulum clock is a clock that uses a pendulum a swinging weight as its timekeeping element.
Pendulum wall clock with huygens weight.
A pendulum clock is a clock that uses a pendulum a swinging weight as its timekeeping element.
On some clocks serving the same purpose meaning a large dial in the instance i m trying to describe the difference can be huge.
The 8 day weight driven movement strikes one stroke every hour and has a matching antique style weight and pendulum.
When you wind a weight driven clock you pull on a cord that lifts the weight.
Pendulums spread over europe as existing clocks were retrofitted with them.
Clocks weight driven and with short pendulums were encased in wood and made to hang on the wall but these new eight day wall clocks had very heavy weights and many fell off weak plaster walls and were destroyed.
The clocks are constructed form a variety of nautral and composite materials including.
The advantage of a pendulum for timekeeping is that it is a harmonic oscillator.
This was a great improvement over existing mechanical clocks.
From its invention in 1656 by christiaan huygens until the 1930s the pendulum clock was the world s most precise timekeeper.
As we will see in a moment the clock uses that.
Wrought iron wall clock with cast chapter ring and roman numerals.
Their best accuracy was improved from around 15 minutes deviation a day to around 15 seconds a day.

Glass metal and woods in various finishes with dials displaying both arabic and roman numerals use the seach facility to narrow dial choice to one specific.
For instance a clock with a heavier weight can store more potential energy and can therefore run longer than a lightweight clock before any winding is required.
That gives the weight potential energy in the earth s gravitational field.
