US Patent No. 1,751,306, granted March 18, 1930 to Frederick B. Cumpston of Blooming Grove, Texas, assignor to Associated Factories Corporation, for a ribless cotton gin. The design uses a series of gin saws on inclined shafts, each turning faster than the one below, with curved brushes that clean lint from the seed. Seed is thrown off by centrifugal force into a conveyor, and lint of different fiber lengths is withdrawn separately. The patent includes a drawing of two figures, a specification, and nine claims.
