Early Continuous Excavator Patent Model

Hand-fabricated mechanical patent model constructed of wood with a tin-clad upper housing, illustrating a continuous material handling concept built around a rotary feed system. 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. Shows age and use throughout including surface wear, oxidation to tin elements, and general handling marks consistent with a utilitarian, hand-built model. Mechanism appears intact as a static display piece. 7" W x 12.5" L x 6" H MM - C-20527 - 050426 For information regarding shipping, please visit our Terms & Conditions page here.
