ABSTRACT:
The invention is a music box which includes a power supply, a motor, gears coupled with the motor, conductors connecting the power supply and the motor, and a music-producing element. At least one platform element is supported atop the housing for pivoting motion about a horizontal axis. Each platform element will support a figurine, character or other object. A linking assembly couples the gears with each platform element. The linking assembly is constrained for substantially linear, reciprocating, motion in a horizontal plane. A rotary output shaft bears a disk having a pin arranged eccentrically thereon. The pin is engagable with one portion of the linking assembly for driving the latter in the linear motion. Each platform element has a depending portion engaging a second portion of the linking assembly so that the linear motion of the linking assembly pushes and pulls the depending element back and forth thereby imparting a rocking motion to the platform means, and hence the figurine mounted atop said platform means.
