Abstract:
A dust retention system for location above a product vessel, said system comprising:a support member adapted to be mounted above the product vessel;a door including an engaging portion detachably mounted on the support member, the door also including a striking portion adjacent the engaging portion with at least a section of the striking portion being constructed of a resiliently flexible material; andan adjustment means for retaining the door in place on the support member and adjusting the desired angle of the door with respect to the support member,such that product falling onto the string portion causes the resiliently flexible material of the striking portion to be deflected by the weight of said product while the engaging portion is retained in place over the support member thereby forcing the door from a closed position, where dust is inhibited from escaping the product vessel, into an open position, where the product passes across the door and into the product vessel, and thereafter the door, without the weight of said product, returns to the closed position under a bias force exerted by said resiliently flexible material.
