The front intake scoop is flanked by angled guides that channel material inward toward a prominent star-shaped wheel, which functions as an agitator or feeder. From there, material would be directed into a curved internal trough and carried through the enclosed body before exiting via a rear discharge box.

Rather than representing a literal production machine, the model appears to explore early solutions for moving loose material-sand, soil, or grain-without reliance on suction systems. The rotary wheel, enclosed pathway, and controlled discharge align closely with late 19th-century developments in continuous excavators and feeder-driven conveyor systems. See less
