Threshing. An ancient process used to separate grain from straw. First invented by Scottish mechanical engineer Andrew Meikle for use in agriculture. It was invented (c. 1784)
Early threshing machines were hand-fed and horse powered. They were the size of an upright piano. Later machines were steam powered, driven by a portable engine or traction engine. In 1834 John Avery and Hiram Abial Pitts devised significant improvements to a machine that automatically threshes and separated grain from chaff. Avery and Pitts were granted a patent in the United States on December 29, 1837. The last picture is of the straw being baled after it has gone through the threshing process. If you notice in the first video, the straw is coming out from the threshing machine at the top and the grain is coming down the chute from the side of the machine and they had bags at the end of the chute that would catch the grain and then tied them shut. Sunday's post was the grain that was being bagged.
