ABSTRACT:
A pendulum clock mechanism including a conventional escapement may be coupled to a conventional pendulum bob by means of a rotatable lever such that the oscillations of the escapement are regular and periodic regardless of misalignments of the clock mechanism with the vertical as defined by gravity. The escapement is driven by a lever which is rotatably fixed to the arm of the pendulum. The pendulum is supported from an independent pivot. The lever and pendulum arm are frictionally coupled such that when the equilibrium position of the pendulum arm is offset from the designed equilibrium position of the clock mechanism, the lever is automatically rotated such that the escapement is still driven about its designed equilibrium position.
