ABSTRACT:
Uniform oscillating movement is imparted to a toy by a tappet rod from an output shaft of a music box drive source by a connecting rod having its opposite ends pivotally connected to a cam assembly on the output shaft and a cam follower arm on the tappet rod to define two pivot axes therewith, whereby rotation of the cam assembly imparts an oscillating movement to the tappet rod at a uniform speed through both halves of each oscillation.
