ABSTRACT:
A motorized coil spring amusement device including a housing containing a motor with a track driven by the motor having dwell and flat portions on which a pair of spaced rollers roll. A vertical shaft extends from each roller up through the housing having a plate fixed to the top thereof. A flexible coil spring is fixed at each end of each of the plates. As the track is rotated, the rollers engage the dwell and flat portions raising the lowering the plates. This results in the coils of the coil spring moving back and forth between the plates. The rotation of the track can be timed to create a uniform transfer of the coils from one plate to the other.
