Andrew Beard spent the first fifteen years of his life as a slave on a small farm in Alabama. A year after he was emancipated, he married and became a farmer in a small city outside of Birmingham. While in Birmingham, he was able to develop and champion his first invention (a plow).
Jackson was born a slave on 03-29-1849 in Jefferson County, Alabama.
Andrew Beard Did Not Have A Legal Education
Born as a slave in 1849 on a plantation in Woodland, Alabama, Andrew Beard was a farmer, carpenter, blacksmith, railroad worker, businessman and an inventor. When he was a farmer near Birmingham, he thought up the idea of inventing a plow. In 1881, he patented one of his plows, which he sold for $4,000 three years later. In 1887, he invented another plow, sold it and used the proceeds to finance a profitable real estate business. In 1892, he patented his rotary engine.
While working in the railroad yards, Andrew suffered a serious accident when he was crushed between two cars while linking them. He lost a leg in the process. Car coupling was an extremely dangerous procedure. Many railroad men lost their lives and limbs while working this job. This fueled Beard's resolve and imagination to create a device that linked cars automatically.
On November 23, 1897 he obtained a patent for his railroad car coupler—the "Jenny Coupler." In that same year, he sold his patent rights to a New York firm for $50,000, which was a substantial sum at that time. The device, improved in 1899, was the precursor of today's linking mechanism.
Beard received a patent relating to the automatic coupler.
Andrew Invented The Plow In 1884, A Rotary Steam Engine In 1892, And An Improvement To Railroad Cart Couplers Called "Jenny Coupler."
