ABSTRACT:
An ambulator for conveying rolls of carpet from a first elevation to a second elevation in a continuous step-wise manner has a fixed frame including a pair of spaced apart inclined frame members having a multiplicity of steps extending thereon from the first elevation to the second elevation, and a movable frame having spaced apart inclined beam members having a similar multiplicity of steps thereon. The profile of the steps on the fixed frame and on the movable frame are identical, and the movable frame is driven in an orbital path raising and lowering while moving longitudinally relative to the fixed frame. As the movable frame orbits it lifts a roll of carpet extending across a first set of steps of the fixed frame and carries it to a second set of steps closer to the second elevation. As the movable frame continues to orbit back to its initial position a second set of steps on the movable frame lifts and carries the carpet from the second set of fixed steps to the next set of steps and continuously in seriatim until the roll is at the second level. The beam members of the movable frame have downwardly extending arms which are journally connected to respective rotatable levers driven from a common source. Depending upon the direction of rotation of the levers the ambulator may raise a roll from a lower elevation to an upper elevation or lower a roll from an upper elevation to a lower elevation.
