Meath's 1906 clock is distributed throughout the gatehouse tower it occupies; it is not possible from the published illustrations to fully reconstruct the appearance of the clock.
Meath's clock is a "free pendulum" (or, given our discussion so far, "free oscillator") clock because as is apparent from the figures there is a communication of energy or information from the oscillator to the escapement, but no corresponding communication from the escapement to the oscillator.
Meath assumed it was.) Meath achieves this goal by isolating a fixed-length column of water (assumed to be of fixed diameter) at each rightward swing and using its constant force to impulse the pendulum.
