Abstract
A motor driven bell sound generation system is constructed such that rotational movement of a motor is converted into reciprocative hammering operation or single directional striking operation of hammer means via a crank means, driving means with radial protrusions on the outer periphery thereof or lever mechanism, whereby the required quality and volume of bell sounding is produced. A resilient means comprising a coil spring-leaf spring combination or single coil spring may be arranged for conversion of the rotational movement of the motor into the hammering or striking operation of the hammer means between the motor and the hammer means. Rotational movement of the motor may be converted into a reciprocative striking operation of the hammer means via a combination of driving member having ratchet on the outer periphery and a leaf spring. Alternatively rotational movement of the motor may be converted into swinging operation of the hammering arm or into reciprocative striking operation of the hammering rod via a worm gear and worm wheel mechanism and lever member.
