Abstract
A spring motor mechanism for use with a child's swing that includes a spring attached to a slip clutch device to prevent the spring from becoming over wound. In addition, the spring motor mechanism includes an indicator for revealing, based upon the amount of torque stored in the spring, the remaining number of child seat oscillations that can occur before the spring must be re-wound, and an adjustable swing height portion to prevent the over-swinging of the child seat.
