Verge Escapement - Verge Pendulum Clocks

Verge Pendulum Clocks

Most of the gross inaccuracy of verge and foliot clocks was not due to the escapement itself, but to the foliot oscillator. The invention of the pendulum around 1656 suddenly increased the accuracy of the verge clock from hours a day to minutes a day . Most clocks were rebuilt with their foliots replaced by pendula, to the extent that it is difficult to find original verge and foliot clocks intact today. A similar increase in accuracy in verge watches followed the introduction of the balance spring in 1658.

Famous quotes containing the words verge, pendulum and/or clocks:

    The ability to get to the verge without getting into the war is the necessary art.... If you try to run away from it, if you are scared to go to the brink, you are lost.
    John Foster Dulles (1888–1959)

    During the first World War women in the United States had a chance to try their capacities in wider fields of executive leadership in industry. Must we always wait for war to give us opportunity? And must the pendulum always swing back in the busy world of work and workers during times of peace?
    Mary Barnett Gilson (1877–?)

    It was a bright, cold day in April and the clocks were striking thirteen.
    George Orwell (1903–1950)
