ABSTRACT:
A twisting pendulum operating apparatus which includes a suspension wire for suspending a pendulum from a support, a rotary shaft which is engageable by gears of a clock for rotating the shaft about its longitudinal axis, a rotor fixed to the shaft, an idle wheel having protrusions along its outer circumference idly fitted to the shaft, permanent magnets on at least one of the idle wheel and the rotor, for magnetically urging the idle wheel to the rotor so that the idle wheel is rotated with the rotor and a connecting piece fixed to the suspension wire intermediate the opposite ends of the wire so as to releasably engage the protrusions, one-by-one, as the idle wheel rotates with rotation of the rotor, thereby to twist the suspension wire.
