- Portable Combined Thresher-Separator, circa 1870 - Thresher-separators threshed the harvested grain, removing the grain and chaff (waste) from the straw, and then winnowed the chaff from the grain, all in a continuous flow. These implements greatly reduced the time required for harvest, increasing yields, while reducing the labor costs. This machine incorporates several Westinghouse-patented improvements to the separator.
