Louis, Missouri and Milwaukee, Wisconsin were more established and prosperous. At the time, other cities in the midwestern United States, such as Cleveland, Ohio St. In 1847, after their father's death, Cyrus and his brother Leander (1819вЂ“1900) moved to Chicago, where they established a factory to build their machines. He also licensed several others across the country to build the reaper, but their quality often proved poor, which hurt the product's reputation. to get his 1845 patent, he heard about a factory in Brockport, New York, where he contracted to have the machines mass-produced. ДЄs word spread about the reaper, McCormick noticed orders arriving from farther west, where farms tended to be larger and the land flatter. He received a second patent for reaper improvements on January 31, 1845.

They were all built manually in the family farm shop.

He finally sold seven reapers in 1842, 29 in 1843, and 50 in 1844. Using the endorsement of his father's first customer for a machine built by McPhetrich, Cyrus continually attempted to improve the design. He did sell one in 1840, but none for 1841. In 1839 McCormick started doing more public demonstrations of the reaper, but local farmers still thought the machine was unreliable. The panic of 1837 almost caused the family to go into bankruptcy when a partner pulled out. The McCormick family also worked together in a blacksmith/metal smelting business. None was sold, however, because the machine could not handle varying conditions. The young McCormick was granted a patent on the reaper on June 21, 1834, two years after having been granted a patent for a self-sharpening plow. He claimed to have developed a final version of the reaper in 18 months. The McCormick design was pulled by horses and cut the grain to one side of the team.Д¬yrus McCormick held one of his first demonstrations of mechanical reaping at the nearby village of Steeles Tavern, Virginia in 1831. A few machines based on a design of Patrick Bell of Scotland (which had not been patented) were available in the United States in these years.

He worked for 28 years on a horse-drawn mechanical reaper to harvest grain he was never able to reproduce a reliable version, however.Д«uilding on his father's years of development, Cyrus took up the project aided by Jo Anderson, an enslaved African-American on the McCormick plantation. As Cyrus' father saw the potential of the design for a mechanical reaper, he applied for a patent to claim it as his own invention. He was the eldest of eight children born to inventor Robert McCormick Jr. Д¬yrus Hall McCormick portrait, held by the National Portrait Gallery in Washington, D.C.Д¬yrus Hall McCormick was born on February 15, 1809, in Raphine, Virginia. He also successfully developed a modern company, with manufacturing, marketing, and a sales force to market his products. His efforts built on more than two decades of work by his father Robert McCormick Jr., with the aid of Jo Anderson, who was enslaved by the family. He was, however, one of several designing engineers who produced successful models in the 1830s. McCormick has been simplistically credited as the single inventor of the mechanical reaper. Originally from the Blue Ridge Mountains of Virginia, he and many members of the McCormick family became prominent residents of Chicago.

Cyrus Hall McCormick (FebruвЂ“ May 13, 1884) was an American inventor and businessman who founded the McCormick Harvesting Machine Company, which later became part of the International Harvester Company in 1902.
