Abstract

An end tube assembly for the outlet gate of a railroad hopper car includes an end tube and an end tube cap for closing the end tube. The cap is pivotally connected to the end tube and there is a diametrically opposed latch between the cap and end tube. The cap has a guide which extends toward and over the end tube and there is a ramp on the end tube in alignment with the guide to coaxially direct the guide and cap on the end tube during closure. There is a lock on the end tube adjacent the ramp to prevent relative circumferential movement between the cap and end tube. The end tube mounts a gasket which faces the end tube cap. The cap has a rim extending outwardly therefrom for contact with the gasket. The extension of the rim gradually varies from at least one area of greatest extent to at least one area of lesser extent to compensate for distortion of the cap when it is latched onto the end tube.
