Although he specified the use of two rudders, Everson made no mention of an engine for turning the paddle wheel."}], "name": [{"label": "patentee", "content": "Everson, Walter"}, {"label": "inventor", "content": "Everson, Walter"}], "topic": [{"label": "subject", "content": "Maritime"}, {"label": "subject", "content": "Patent Models"}], "place": [{"label": "associated place", "content": "United States: New York, New York City"}], "physicalDescription": [{"label": "Physical Description", "content": "wood (overall material)"}, {"label": "Measurements", "content": "overall: 12 in x 4 1/4 in x 2 3/4 in; 30.48 cm x 10.795 cm x 6.985 cm"}], "dataSource": [{"label": "Data Source", "content": "National Museum of American History"}], "objectType": [{"label": "Object Name", "content": "tugboat, patent model"}, {"label": "Object Name", "content": "patent model, tug for towing canal boats"}, {"label": "Object Type", "content": "Patent Model"}, {"label": "Other Terms", "content": "patent model, tug for towing canal boats; tugboat; Maritime; Paddle Wheel, Center"}]}}, "url": "edanmdm:nmah_843810", "hash": "64664033daced271dc11f08e5df41f1b23ad27b4", "docSignature": "217c159316cfbc9449383ca3ae6327a3", "timestamp": 1663782597, "lastTimeUpdated": 1653680878, "title": "Patent Model, Tug for Towing Canal Boats"}
