Abstract

See full text

The present invention relates to a motor driven type bell striking device to be employed in electric bells. The device incorporates a cam coupled with the rotating drive shaft of an electric motor, the cam translating the rotary motion of the motor to an oscillating action which serves to impel a piston, the piston then impelling a striking member which is coupled with the base or frame of the bell by a spring. In one preferred embodiment, the previously mentioned spring is a coil spring which wraps around the piston. In a second preferred embodiment, a leaf spring is employed. In both embodiments, the energy of the moving piston is translated into inertia in the striking member. Because the striking member is relatively free floating in the direction in which it moves, a sharp, clear ring sound is made possible with each impact of the striking member.
