Abstract

A simulated pendulum clock has a pendulum which rocks to and fro for decorative purposes only thereby simulating a pendulum clock of the type having a rocking pendulum for timekeeping purposes. A transmission wheel is rotationally driven by the timepiece movement of the clock and a friction clutch mechanism transmits the rotational movement of the transmission wheel to a rotating member whenever the load on the rotating member is less than a predetermined value and otherwise enables slipping of the transmission wheel relative to the rotating member. A toothed escape wheel is coaxially mounted with the rotating member and is connected thereto through a coil spring which applies a rotating torque to the escape wheel. The teeth of the escape wheel coact with a pair of pallet pins of a pallet which is mounted to undergo rocking movement in response to alternative engagement and disengagement of the pallet pins with the escape wheel teeth. A pendulum is fixedly secured at one end to the clock case and hangs downwardly therefrom in juxtaposition with the pallet, the pendulum being connected to the lower end of the pallet so as to transmit the rocking movement of the pallet into a rocking two-and-fro movement of the pendulum thereby simulating a pendulum clock.
