Abstract
A gasket for a hopper outlet is disclosed, particularly for use with an unloading outlet for a railway hopper car. The car has hopper walls which slope inwardly and downwardly, and a hopper frame is carried by the lower portions of the hopper walls. The outlet has an outlet frame which mates with and is secured to the hopper frame, with a seal between the hopper frame and the outlet frame for effectively sealing the outlet frame to the hopper frame, and for effectively preventing entrappment of powdered or particulate lading at the interface of the hopper frame and the outlet frame. In one embodiment, such a seal may be retrofitted to existing outlets.
