Watch on. [8] This rotates the verge and foliot in one direction, and rotates the second pallet into the path of the teeth on the opposite side of the wheel, until the tooth slides off the end of the pallet, releasing it. Each swing of the balance wheel thus allows one tooth of the escape wheel to pass, advancing the wheel train of the clock by a fixed amount, moving the hands forward at a constant rate.

In a verge pendulum clock (see picture) which appeared after the pendulum was invented in 1656, the escapement was turned 90 so the verge rod was horizontal, while the escape wheel's axis was vertical, located under the verge rod. The system was also sensitive to changes in input power, making spring-powered systems less accurate. All Rights Reserved. It is a dead beat escapement. [7] The rate of the clock could be adjusted by moving the weights in or out on the foliot. A gear train (wheel train) that steps up the speed of the power so that the pendulum can use it.

Universal Verge Kit comes in a set of 3 pieces. This caused a shift from measuring time by continuous processes, such as the flow of liquid in water clocks, to repetitive, oscillatory processes, such as the swing of pendulums, which had the potential to be more accurate.
