COVE

One of the more basic models of the Threshing machine was designed to be "labor-saving" by making the process of threshing require as little manual labor as possible. This one was equipped with a series of belts that were driven by a hand crank that would help move the pulse to the different sections of the machine that would vibrate, roll, and slap the stock that would essentially remove the wheat, barley, oat chaff from the pulse.
