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. The seeds which are being discharged from the gin roller may either pass through finger-like grid structure disposed adjacent the kicker device or they may be carried between the kicker device and the ginning saw by the kicker device for ultimate discharge. The lint fiber continues to rotate with the teeth of the ginning saw drum to a discharge point where a rotating cylinder-like brush device doffs the lint fiber from the saw teeth for ultimate discharge.
