US Patent No. 1,751,307, granted March 18, 1930 to Frederick B. Cumpston of Blooming Grove, Texas, assignor to Associated Factories Corporation, for a cotton-gin machine. It describes a ribless gin in which a central screw conveyor carries cotton past surrounding carding saws rotating in the same direction at progressively increasing speeds. The saws remove lint from the seed, and brushes doff the lint into flues. A slightly wider gap lets wadded cotton pass to a stripper. The text includes the description, thirteen claims and a sheet of drawings (Figs. 1 and 2). The machine can also relint cotton seed.
