Abstract:
An auxiliary locking and restraint device for use on a railroad rail car having a plug door, said locking and restraint device comprising:a reinforcing plate having means for mounting onto a central planar portion of the bottom edge of the outer surface of the door,said reinforcing plate having a sealing tab pivotally mounted thereon, said sealing tab constrained to pivotal movement in a plane substantially perpendicular to that of said reinforcing plate, said sealing tab having an aperture therethrough that is substantially parallel to its pivotal axis,a mounting frame adjacent to said reinforcing plate, said mounting frame being adapted to be mounted on an outer surface of the rail car that is parallel to the outer surface of the door,a bolt element pivotally mounted to said mounting frame and constrained to movement within a plane that is substantially parallel to that of said reinforcing plate, said bolt element's pivotal axis being perpendicular to said pivotal axis of said sealing tab, said bolt element having an aperture therethrough that is substantially perpendicular to its pivotal axis,whereby when said mounting frame and said reinforcing plate are mounted on the rail car and its door is in a fully closed position, said bolt element can be swung parallel to the door's outer surface, up into a vertical position that blocks outward movement of the door and said sealing tab can be swung perpendicular to the door's outer surface, down to a vertical position that blocks pivotal movement of said bolt element and said apertures of said sealing tab and said bolt element are adjacent and axially aligned for receiving a seal therethrough.
