Patent for an electric-current control or rheostat to be used when a "close, accurate, and absolute graduation of the current is necessary" (lines 15-16), in places "where a very delicate graduation is necessary either in passing the plain galvanic current or where the current is used for producing anesthesia" (lines 19-21).

Patent for a cotton gin that removes lint-cotton from the saws using an air-suction mechanism instead of a brush, which pose a fire hazard and can impair the gin's effectiveness. An air-blast mechanism is also an ineffective method of cleaning lint-cotton from the saws. The air-suction mechanism sucks "the lint-cotton directly from the rear portions of the saw-teeth independently of and without a brush, and an apparatus for preventing the withdrawn lint-cotton from passing into and through the air-suction apparatus" (lines 84-89).
