Abstract

A mechanism for transmitting the power output of a music box to an ornament supported thereon, wherein the output shaft of the music box rotates an eccentric stub that is engaged within a slide link supported for vertical movement on a pair of guide rods. The ornament is supported by a tappet rod having a lower end secured to either the slide link or the drive stub, so that operation of the music box will impart the desired movement to the ornament.
