Abstract
Abstract An apparatus for removing foreign matter from cotton includes an elongated frame having a plurality of rollers rotatably supported in closely spaced side-by-side relation therealong for conveying cotton over the rollers from one end of the frame to the other in response to rotation of the rollers in unison. The rollers have a plurality of protrusions so that the cotton is vertically shaken as it is conveyed over the rollers with the result that foreign matter falls between the rollers away from the cotton. The protrusions may be the transversely extended corners of polygonal shaped rollers, the corners being adapted to strike the cotton in response to rotation of the rollers for a more vigorous shaking action. A plate may be supported in vertically spaced relation above the rollers for rebounding cotton which is thrown up by the rollers back toward the rollers. A conveyor belt below the rollers collects the foreign matter which drops therethrough.

Claim 1
Independent Claim
209 words
In combination with a cotton gin having an intake opening for receiving cotton therein and a conveyor for supplying cotton thereto, the improvement comprising an apparatus for removing foreign matter from the cotton, said apparatus being interposed between said intake opening and conveyor and comprising, an elongated frame means having one end portion disposed in communication with said conveyor for receiving cotton therefrom and an opposite end portion disposed in communication with said intake opening for delivering cotton thereto, a plurality of rollers extended transversely of said frame means, means for rotatably supporting said rollers in side-by-side closely spaced relation on said frame means whereby said rollers cooperatively define a cotton supporting conveyor surface, means for rotating said rollers in unison whereby cotton discharged from said conveyor means onto said one end portion of the frame means is conveyed on said rollers to the opposite end portion of the frame means toward said intake opening, said rollers having a plurality of protrusions thereon whereby said cotton is generally vertically shaken in response to rotation of said rollers, and an elongated plate means disposed generally parallel to and in vertically spaced relation above said rollers at a position for rebounding cotton thrown upwardly by said rollers back to said rollers.
