  • Sound-producing attachment for a clock pendulum
    Patent number: 5285429
    Abstract: A noise producing device that produces a tick-tock sound is provided for use on simulated pendulum clocks that otherwise produce no sound. The device is constructed of an elongated cage member having two extremities provided with hard abutment closures. The cage member is orthogonally associated with the pendulum. A metal ball is confined within the cage, and is adapted to roll back and forth with each swing of the pendulum mechanism. The impact of the ball with each closure produces the desired sound.
