Abstract: Apparatus for removing a certain amount of moisture from moisture laden cotton bolls. The apparatus includes a hopper for receiving the moist cotton bolls and rotatable dispensing structure for controllably metering optimum measures of moist cotton bolls into a fast moving airstream leading into a plenum. The midsection of the plenum houses at least one rotatably driven saw drum which is rotated at a controllable slow rate, e.g., 10-20 RPM. The teeth of the saw drum are arranged with the pointed tip portions respectively trailing the root portions or successively pointed into the airstream as the saw drum is rotated. Accordingly, the cotton bolls are impaled upon the pointed tip portions by the force of the circumfluent air. Therefore, movement of the cotton bolls through the midsection of the plenum is controllably retarded since the velocity of the circumferential surface of the saw drum determines the period of time in which the cotton bolls are exposed to the fast moving airstream, i.e.

Abstract: An apparatus for removing trash from seed cotton. The comingled seed cotton/trash are conveyed by air velocity into the housing of the apparatus wherein they are made to follow the outer curve of the top panel until arrested by a spiked rotating beater cylinder having a first grid section disposed thereabout for expelling the rushing air and the entrained minute pieces of trash. As the beater directs the remaining portion of cotton/trash toward a rotating primary saw drum, the larger pieces of trash gravitate into a bypass hopper from which certain structure reclaims the seed cotton which may be comingled therewith. The reclaimed seed cotton is redirected onto the primary saw drum which also engages and holds the seed cotton being thrown thereon by the beater cylinder. A portion of the seed cotton impaled upon the primary saw drum has considerable intermediate size pieces of trash comingled therewith.

Abstract: A cotton ginning apparatus having a rotating ginning saw drum for engaging and holding the fibers of the seed cotton. A cylinder-like serrated kicker device extends across the path of the seed cotton being admitted for directing the seed cotton onto the ginning saw cylinder. The seed cotton, being held upon the ginning saw cylinder, is brought into engagement with a rotating spiral shaped gin roller. The gin roller has several spiral conveyor-like vanes which respectively have left and right-hand twists thereto that terminate midway between the outer ends thereof. The gin roller rotates with a greater surface velocity than that of the ginning saw cylinder, thus a lateral wiping action acts upon the seed cotton while the teeth of the ginning saw cylinder have a continuous pull on the fibers. The wiping action of the gin roller and the ever present pull on the fibers separates the seeds from the fiber, i.e., the removed seeds being carried inwardly to the center of the gin roller for discharge therefrom.
