Abstract
A wheel supported open top receptacle such as a railway car is provided with a liner arrangement comprising a plurality of belt members arranged between the end walls of the car with the sides of adjacent ones of the belts overlapped in the direction between the end walls, and with each belt overlying the side walls and bottom wall of the car. One end of each belt member is attached to the upper end of the corresponding one of the side walls and, by upward displacement of the other end, each belt is adapted to be displaced upwardly relative to the car. Material in the car is progressively unloaded laterally outwardly of the car by sequential displacement of the belts in accordance with the pattern of overlap.
