US Patent 3,231,939, granted to Frank E. Deems of Birmingham, Alabama, for a saw-type cotton gin that removes the roll box. Seed cotton passes in a thin stream over a bed of rotating pinned drums or saw cylinders, between the huller ribs and the ginning ribs. This is meant to cut fiber damage, saw wear, and power use. The document has three sheets of drawings (Figs. 1-10), the specification describing three variants, two claims, and a list of earlier patents cited.
