With this invention, Joseph Francis sought to reduce the cost of constructing boats by simplifying the process. He proposed setting up a reusable frame over which very narrow planks would be bent to form the hull. The planks would be fastened together by bolts or nails driven through their edges, and no complicated joinery was to be done where the curves of the hull converged at bow and stern. \u00e2\u0080\u009cOrdinary workmen and machinery\u00e2\u0080\u009d could build this simple boat, he wrote. It would save on material, as none of the planks would overlap, and it would not require caulking, \u00e2\u0080\u009cas the narrow planking is drawn so closely together by the . . . nails . . . .\u00e2\u0080\u009d Finally, Francis claimed that the boat\u00e2\u0080\u0099s metal fasteners, buried between the planks, would not be likely to corrode and loosen the structure. Francis may have used this technique in his own boat works, but it was otherwise ignored by the nation\u00e2\u0080\u0099s many skilled boat builders."}], "name": [{"label": "patentee", "content": "Francis, Joseph"}, {"label": "inventor", "content": "Francis, Joseph"}], "publisher": [{"label": "Related Publication", "content": "On the Water online exhibition"}, {"label": "Related Web Publication", "content": "http://americanhistory.si.edu/onthewater"}], "topic": [{"label": "related event", "content": "Expansion and Reform"}], "place": [{"label": "associated place", "content": "United States: New York, New York"}], "physicalDescription": [{"label": "Physical Description", "content": "wood (overall material)"}, {"label": "Physical Description", "content": "metal (fittings material)"}, {"label": "Physical Description", "content": "paper (card material)"}, {"label": "Measurements", "content": "overall: 5 3/4 in x 39 1/2 in x 6 in; 14.605 cm x 100.33 cm x 15.24 cm"}], "dataSource": [{"label": "Data Source", "content": "National Museum of American History"}], "objectType": [{"label": "Object Name", "content": "life boat, model"}, {"label": "Object Name", "content": "patent model, lifeboat"}, {"label": "Object Type", "content": "Patent Model"}]}}, "url": "edanmdm:nmah_1316595", "hash": "75690f9d9198ef72e587c85bd324865a8e8122ef", "docSignature": "43febba1d1bbc42038b93342efb4c9f4", "timestamp": 1663783025, "lastTimeUpdated": 1655973789, "title": "Patent Model, Method of Building Wood Boats"}
