Patent ID: 7261634

Claim:
An automatically deployable and storable cover apparatus for a cotton conveyor duct of a cotton harvester, comprising: a cover member pivotally mounted on a cotton conveyor duct so as to be located above a discharge outlet of the duct, the discharge outlet being spaced from an inlet opening of a downwardly movable cotton receiver, the cover member being pivotally movable between a first position extending at least partially across the discharge outlet, and a second position extending outwardly from the outlet toward the inlet opening of the cotton receiver, the cover member when in the first position being automatically pivotally movable to the second position by a force exerted thereagainst by a flow of air discharged from the outlet, the cover member when in the second position extending from the duct to a location below a structural element of the cotton receiver adjacent to an upper periphery of the inlet opening thereof so as to be positioned for directing a flow of air and cotton discharged from the discharge outlet into the inlet opening, and such that the structural element of the cotton receiver can be moved downwardly against the cover member to move the cover member to the first position; and a locking element configured for automatically holding the cover member in the second position and releasing the cover member when the structural element of the cotton receiver is moved downwardly thereagainst, for allowing the cover member to be moved thereby to the first position, wherein the locking element comprises a magnetic element disposed for magnetically holding the cover member in the second position.
