BATTERY-OPERATED CHILD'S SWING Abstract Of The Disclosure A child's swing or the like of the type having a supporting frame and a horizontal pendulum axle journaled in the frame and from which a seat is suspended. A motor is mounted on the horizontal pendulum axle for movement with the axle. A crank is mounted on the axle for move- ment with the axle, and is driven for rotation with respect to the axle by the motor. A torsional spring is fixedly mounted with respect to the frame. The spring is in spaced relation to the axis of the horizontal pendulum axle and is substantially parallel to it. A sliding coupling couples the crank to the torsional spring. Rotation of the crank imparts a force to the torsional spring through the coupling, resulting in a force moment about the axis of the horizontal pendulum axle. The force moment causes the axle to rotate about its axis, thereby causing the seat to swing.
