On May 22, 1849, Abraham Lincoln was granted Patent No. 6469 by the U.S. Patent Office on a device for "Buoying Vessels Over Shoals." As noted by the U.S. Patent and Trademark Office, Lincoln's "invention consists of a set of bellows attached to the hull of a ship just below the water line. On reaching a shallow place, the bellows are filled with air and the vessel, thus buoyed, is expected to float clear."
Although the device was never actually manufactured, Abraham Lincoln remains today as the only United States President to hold a patent. A scale model of the invention is on display at the Smithsonian Institution National Museum of American History. /blockquote>
