Clock 4 was designed with a Verge and Foliot escapement that was used before the pendulum was introduced to clockmakers. Most of the gross inaccuracy of the early verge and foliot clocks was not due to the escapement itself, but to the foliot oscillator. The moment of inertia of the foliot or balance wheel controls the oscillation rate, determining the rate of the clock. Its invention is important in the history of technology, because it made possible the development of all-mechanical clocks. The torque or power that is developed within the clock gear train via springs or weights, is released to the pendulum through the escapement, and it is the equal distribution of power that keeps the pendulum swinging. I found three references for "strip pallets" and none for "strap pallets". Yeah, I wasn't actually talking about the whole gear just the wheel on the shaft. Repeat this process until the equilibrium is established and the sound that is heard is a clear and distinct "tick-tick", which indicates the pendulum clock escapement is correctly adjusted.
