  • Patent number: 6533639
    Abstract: Toy figures carry cargo items from one building to another and return without the items to appear to have unloaded the items. This is achieved with an electric motor driving gears connected to two parallel belts moving in opposite directions between the buildings at opposite ends of a platform. Duplicate figures are secured on each belt with one set of figures moving in one direction carrying items and the other set moving in the other direction not carrying items. Figures on the upper surfaces of the belts rotate about roller supports at the ends and are returned inverted along the lower belt surfaces. The belt ends and lower surfaces are obscured by the end buildings and side walls so that only the figures on the upper belts are seen moving in opposite directions with and without loads to provide the desired illusion.
