Abstract
Abstract An upright housing, having a plurality of spaced-apart apertures in its wall arranged in a horizontal plane, supports an electric motor driving a crank member for rotation in the plane of the apertures. An elongated flexible member, connected at one end with the crank member and entrained through a selected one of the apertures, is connected at its other end with an article to be animated by the crank member moving the flexible strand through the selected aperture in a reciprocating action.
