{"product_id":"early-continuous-excavator-demonstration-model","title":"Early Continuous Excavator Patent Model","description":"\u003cp\u003eHand-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.\u003cbr\u003e\n\u003cbr\u003e\nRather 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.\u003cbr\u003e\n\u003cbr\u003e\nShows 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.\u003cbr\u003e\n\u003cbr\u003e\n7\" W x 12.5\" L x 6\" H\u003cbr\u003e\n\u003cbr\u003e\nMM - C-20527 - 050426\u003c\/p\u003e\n\n\u003cp\u003eFor information regarding shipping, please visit our Terms \u0026amp; Conditions page \u003ca class=\"GeneratedLink\" href=\"https:\/\/industrialartifacts.net\/pages\/shipping\" target=\"_blank\"\u003ehere\u003c\/a\u003e.\u003c\/p\u003e\n","brand":"Industrial Artifacts","offers":[{"title":"Default Title","offer_id":44042973478955,"sku":"C-20527","price":8750.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0194\/8170\/files\/20b7b6a4-1137-54eb-b692-5429db155393.jpg?v=1778189107","url":"https:\/\/industrialartifacts.net\/products\/early-continuous-excavator-demonstration-model","provider":"Industrial Artifacts","version":"1.0","type":"link"}
