Abraham Lincoln's patent relates to an invention to buoy and lift boats over shoals and obstructions in a river. Abraham Lincoln conceived the invention when on two occasions the boat on which he traveled got hung up on obstructions. Lincoln's device was composed of large bellows attached to the sides of a boat that were expandable due to air chambers. Filed on March 10, 1849, Lincoln's patent was issued as Patent No. 6,469 later that year, on May 22. His successful patent application led to his drafting and delivering two lectures on the subject of patents while he was president.

Contents

Lincoln was at times a patent attorney and was familiar with the patent application process as well as patent lawsuit proceedings. Among his notable patent law experiences as a result of his patent was litigation over the mechanical reaper; both he and his future Secretary of War, Edwin Stanton, provided counsel for John Henry Manny, an inventor. The original documentation of Lincoln's patent was rediscovered in 1997.

The invention stemmed from Lincoln's experiences ferrying travelers and carrying freight on the Great Lakes and some midwestern rivers. [1] In 1860, Lincoln wrote his autobiography and recounted that while in his late teens he took a flatboat down the Ohio and Mississippi Rivers from his home in Indiana to New Orleans while employed as a hired hand. The son of the boat owner kept him company and the two went out on this new undertaking without any other helpers. [2]

Lincoln made an additional trip a few years later after moving to Macon County, Illinois, on another flatboat that went from Beardstown, Illinois, to New Orleans. John D. Johnston (Lincoln's stepmother's son) and John Hanks were hired as additional laborers by Denton Offutt to take a flatboat of merchandise down the Sangamon River to New Orleans. Before Offutt's boat could reach the Illinois River, it got hung up on a milldam at the Old Sangamon town seven miles northwest of Springfield. [2] Lincoln took action, unloading some cargo to right the boat, then drilling a hole in the bow with a large auger borrowed from the local cooperage. After the water drained, he replugged the hole. With local help, he then portaged the empty boat over the dam, and was able to complete the trip to New Orleans. [3]

Lincoln started his political career in New Salem. Near the top of his agenda was improvement of navigation on the Sangamon River. Lincoln's law partner and biographer, William H. Herndon, also reports an additional incident in 1848: a boat Lincoln came to from his steamboat was stranded on a shoal. The boat's captain ordered his crew to gather together all the empty barrels, boxes, and loose planks and force these objects under the sides of the steamboat to buoy it over the shallow water. The boat gradually swung clear and was dislodged after much manual exertion. [2] This event, along with the Offutt's boat/milldam incident, prompted Lincoln to start thinking about how to lift vessels over river obstructions and shoals. [4] [5] He eventually came up with an invention to achieve this, which involved flotation bladders. [6]

Lincoln labeled his invention Buoying Vessels Over Shoals and it was used to get them over shoals. [7] He envisioned a system of waterproof fabric bladders that could be inflated when necessary to help ease a stuck steamboat over such obstacles. [8] When crew members knew their ship was stuck, or at risk of hitting a shallow, Lincoln's invention could be activated, which would inflate accordion-shaped air chambers along the sides of the watercraft to lift it above the water's surface, providing enough clearance to avoid a disaster. [9] As part of the research process, Lincoln designed a scale model of a ship outfitted with the device. [10] This model (built and assembled with the assistance of a mechanic from Springfield named Walter Davis [10] ) that was originally taken to the United States Patent and Trademark Office in Washington [11] is now on display at the Smithsonian Institution. [12] At the time the patent was issued, Lincoln was a congressman. He is the only United States president to be a patentee. [12]

After reporting to Washington for his two-year term in Congress beginning March 1847, Lincoln retained Zenas C. Robbins, patent attorney. [13] [14] Robbins most probably had drawings done by Robert Washington Fenwick, his apprentice artist. [15] Robbins filed the application on March 10, 1849, [13] which was granted as Patent No. 6,469 on May 22, 1849. [16] Lincoln's patent is the result of Offutt's flat-boat experience he had back in 1831. [17]

The device was never produced for practical use [1] [2] and there are doubts as to whether it would have actually worked. Paul Johnston, curator of the maritime history department at the Smithsonian, came to the conclusion that the version Lincoln made was not practical because it required too much force to make it operate as intended. [1]

Lincoln took his four-year-old son Robert Todd to the Old Patent Office Building in 1847 [18] to the model room to view the displays, sowing one of the youngster's fondest memories. [13] Lincoln himself continued to have a special affinity for the site that covered two city blocks and is a columned structure much like ancient Roman architecture. [19]

Legacy

Lincoln's exposure to the patent system, as an inventor and as a lawyer, engendered deep beliefs in its efficacy. Patent law in the United States has a constitutional foundation which is supported by the country's founders, and was viewed as an indispensable engine for economic development. [20] It led him to draft and deliver two lectures on the subject when he was president. [21] Lincoln had an attraction to machinelike accessories all his life, which some say was hereditary and handed down to him from his father's interest in labor-saving equipment. He made speeches on inventions before he became president. He said in 1858, "Man is not the only animal who labors; but he is the only one who improves his workmanship." [1] [2]

Lincoln admired the patent law system because of the reciprocal benefits it furnished both the inventor and society. In 1859 he noted that the patent system ". . . has secured to the inventor, for a limited time, the exclusive use of his invention; and thereby added to the interest of genius in the discovery and production of new and useful things." [2] [22] He described the discovery of America as the most important development in the world's history, followed second by the technology of printing and third by patent laws. [23]

Lincoln was himself a patent lawyer. [24] He won an unreported patent infringement case for the defendant early in his legal career titled Parker v. Hoyt. A jury found that his client's waterwheel did not infringe the intellectual property rights of another. A large professional fee, one of his largest, came from working on the "Reaper Case" of McCormick v. Manny and being successful with its outcome. [25] He was co-counsel for the defendant with two aggressive and preeminent Pennsylvania patent attorneys, George Harding, and Edwin M. Stanton. Although Lincoln was prepared and well-paid, his co-counsel thought him too naive and unsophisticated to be allowed to present the argument by himself. He went home unheard, however Manny won the case in an opinion authored by Supreme Court Justice John McLean. [26] [27] Upon Lincoln's taking office, he offered Harding the opportunity to become Commissioner of Patents, which was refused. He later offered the job and position of the United States Secretary of War to Stanton, who accepted and served. [13] [28] Lincoln's final patent case was Dawson v. Ennis. It occurred between his presidential nomination and the election. His electoral triumph was juxtaposed with a litigation loss for his client. [8] [13]

The original 1846 patent drawing was discovered in the Patent and Trademark Office of the director in 1997. [29] Its only omission is the usually required inventor's signature in a lower corner. [30] The Smithsonian Institution acquired about 10,000 patent models, including Lincoln's. The Engineering Collection includes about 75 maritime inventions; its Maritime Collections holds a replica, the original being deemed too delicate to loan out. The Smithsonian department of maritime history Historical Collections Department retains a duplicate of the original patent papers. [30]

The McCormick family of Chicago and Virginia is an American family of Scottish and Scotch-Irish descent that attained prominence and fortune starting with the invention of the McCormick Reaper, a machine that revolutionized agriculture, helped break the bonds of slavery, and established the modern grain trade by beginning the mechanization of the harvesting of grain. Through the McCormick Harvesting Machine Company and later, the International Harvester Company and other investments, the McCormicks became one of the wealthiest families in America. The name became ubiquitous in agriculture starting in the 19th century and the press dubbed the McCormicks the "Reaper Kings". Later generations expanded into media and publishing, finance, and real estate. Various family members were well known as civic leaders. They are descended from an influential leader of modern agriculture, inventor Robert McCormick Jr. (1780–1846), and Mary Ann "Polly" Hall of Steeles Tavern, Virginia. The family is Presbyterian.
