ABSTRACT:
A pendulum clock mechanism may have an escapement coupled to a conventional pendulum bob by means of an anchor arbor which is frictionally or slip coupled to an anchor having at least a pair of pallet pins symmetrically disposed thereon for engagement to an escape wheel. The pallet pins engage the escape wheel in a conventional manner to regulate the operation of a conventional clock gear train. The anchor automatically rotates to a position of design equilibrium regardless of improper vertical installment of the clock or excessive torques applied to the escapement mechanism.
