ABSTRACT:
A bi-motional cradle has a base with rollers affixed along each of two sides. A motor mounted on the base drives a crank arm which imparts to and fro translational motion to a cradle frame which rests upon the rollers of the base. A mediate frame member which lies within the cradle frame supports a second motor. The second motor has a crank arm rotably attached thereto. A cradle is suspended from the cradle frame by means which allow the cradle to hang freely and oscillate. The second motor's crank arm engages the cradle during a part of that crank arm's rotational motion. As the second motor's crank arm engages the cradle, it imparts a motion to the cradle that causes the cradle to swing, or oscillate. A baby lying in the cradle is soothed by a gentle, steady, two-directional motion.
