Patent for a cotton cleaner that provides "certain improvements in machines for cleaning lint cotton, and especially to provide a machine of this character which is intended to be arranged in the common lint flue, so as to occupy a position between the ordinary condenser in the lint room, and the nearest gin thereto" (lines 9-16). The cotton is thoroughly cleaned after leaving the gin, so that motes, stems, sticks, dry leaves, sand, &c. will be separated from the cotton.
