Abraham Lincoln received Patent No. 6469 on May 22, 1849 for a hydraulic device to lift boats over shoals, an invention which was never manufactured. However, it did make him the only U.S. president to hold a patent. A scale model of his invention can found at the Smithsonian Institution in Washington, D.C.
As more detail, Lincoln's invention had a series of bellows located in a ship's hold. The bellows would be applied to lift the ship over river obstructions or areas which the ship required more water depth.
The purpose was to enable new and larger ships to reach small river side towns, allowing cargo to be received or sent.
