  • Patent number: 4448410
    Abstract: A baby swing has a seat suspended from a horizontal rocking bar by two hangers. Mounted to the bar is a generally horizontally-mounted wheel or disc having a predetermined unequal weight distribution. A stationary DC motor drives the rim of the wheel which, as it rotates, causes the wheel and the shaft about which it revolves to rock back and forth, thereby also causing the rocking bar to do the same. The bar imparts corresponding swinging motion to the seat for a period of time determined by the current drain of the DC motor when operated from batteries.
