Abstract: Disclosed is a transportation device comprised of a series of load carrying components connected together so that the distance between the components vary thereby allowing the components to move in a closed loop path. Rotatingly driven endless screws are positioned along the closed loop path and are engaged by a projection associated with the component as a particular component moves along a screw. The thread pitch of the screws is arranged to control the distance between adjacent component and the speed of the components.
