Eli H. Janney
Eli Hamilton Janney (November 12, 1831 – June 16, 1912) was the inventor of the modern knuckle coupler that replaced link and pin couplers on North American railroads.
Biography
[edit]He was born in 1831 to Daniel Janney and Elizabeth Avis Haines in Loudoun County, Virginia. He studied briefly at a seminary.[1] He married Cornelia Hamilton (1833–1889).
In the American Civil War, Janney achieved the rank of major for the Confederate States of America,[1][2] and served on the staff of General Robert E. Lee.[2]
After the war, he was a dry goods clerk in Alexandria, Virginia; he spent many of his lunches whittling his concept out of a block of wood for a replacement to the railroads' link and pin couplers that were in wide use. On April 1, 1873, Janney filed for a patent titled "Improvement in Car-Couplings" describing the knuckle-style couplers that are in use on railroads today. He was awarded U.S. patent 138,405 on April 29, 1873.[1]
He died on June 16, 1912, in Alexandria, Virginia and was buried in Ivy Hill Cemetery. The City of Alexandria named one of their streets in his honor, Janney's Lane.[3]
Janney's coupler and the Westinghouse air brake are generally regarded as being the two most significant safety inventions in U.S. railroads between the end of the Civil War and 1900.
