A short 1869 notice from the Journal of the Franklin Institute describing the Champion Gin and Huller, a cotton gin exhibited by Richard R. Gwathmey. It explains the machine's parts with a labeled cross-section diagram (saws, hulling roller, carrying rollers, brush, wire gauze cylinder, mote board, seed screw). It claims the reverse-running saws let the machine gin cotton in the boll with hulls included, and gives a calculation of the planter's financial gain over hand-picking.
