Cotton Gin. (open access)

Cotton Gin.

Patent for a new and improved cotton gin. This design "consists in the combination of the bevel-edged boards with the saws and brush, so as to facilitate the transfer of the cotton from the saws to the arc-shaped support consisting of the bevel-edged boards set at a short distance apart, and to thus straighten the fiber or lint. This gives the lint cotton a finer and lighter appearance, causing a ready allowance of a considerable addition to the usual price" (lines 8-17).
