ABSTRACT:
A device for driving multiple twist pendulums for a table clock is constructed such that the twist pendulums are arranged so as to operate independently of each other and are driven to rotate in directions opposite to each other. One twist pendulum is connected to a first pendulum shaft which depends from a body casing a greater distance than a second pendulum shaft which is in the form of a cylinder and which concentrically surrounds the first pendulum shaft. A gear train interconnects the pendulum shafts with a single driving wheel and a driving coil to provide the motive force to drive the twist pendulums.
