Abstract
An outlet assembly for application to hoppers of railroad hopper cars and the like, and slidably mounting a gate for movement between open and closed positions, in which the gate slideway is defined by trackway forming members disposed at either side edge of and across the mid portion of the gate outlet port, and having the respective load supporting surfaces each lined with a special liner formed from an ultra high molecular weight polymeric material that is of dry self lubricating characteristics. The gate side edges ride on the liners of the track forming members at the respective side edges of the outlet port, and the respective gate side edges and the liners supporting same cooperate to effect a bulk material seal at the respective side edges of the gate. The liner across the mid portion of the outlet assembly outlet port is mounted for limited lost motion movement relative to the gate and cooperates with a stop forming abutment to provide a gate break away action when the gate is opened under loaded conditions.
