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 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.
