President Andrew Jackson did not have any inventions. However, there was an inventor by the name of Andrew Jackson who invented the Jenny coupler and the plow.
The Janney coupler was named after Eli H. Janney who patented the invention in 1873. The Janney coupler was an improvement in railroad car couplers that became the standard for the railroad freightcar couplers.
Andrew Beard's first patent was for a plow he designed in 1881. After selling the rights to this original patent, he went on to patent a second plow design in 1887. In 1892, Andrew Beard patented a design for a rotary steam engine. He is sometimes falsely credited as the original inventor of the automatic railroad coupler, who was actually Eli H. Janney (the knuckle coupler). In fact, Andrew Beard patented a variant design in 1897, which is commonly called the Jenny Coupler. These serve to join railroad cars together, a dangerous job that had resulted in many injuries. For his work on railroad coupler design, Andrew Beard has been inducted into the National Inventors Hall of Fame in Akron, Ohio.
Coupler is a connection of two things, particularly involving mechanical components, systems, music, instruments, and transportation, such as two railroad cars, organ keyboards, manuals,
