Abstract
This invention concerns an inlet opening protector for use during maintenance operations on railroad hopper cars. The protector shields the coaming of a hopper car hatch and closes off the hatch opening. The protector includes a throat liner and a short liner. The throat liner has a frusto-conical skirt portion which defines interior and exterior edges. A radical flange is attached to the internal edge of the skirt. A plate member is attached to the external edge and covers the space defined by that edge. The surfaces of the skirt are tapered and sized to fit partially through the coaming. The short liner has a radial collar and an annular ferrule which fit around the skirt. The ferrule frictionally engages the coaming and the skirt to hold the throat liner in place in the inlet opening.
