ABSTRACT:
A railway freight car adapted particularly for transporting coal or like granular materials where a flexible cover is adapted to be draped over the materials so as to protect them from the elements when the car is being transported from one place to another. In the transport of coal in particular, there are several problems presented if the coal is left uncovered during transport. First, there is the problem of coal dust particles flying in the surrounding atmosphere due to the aspiration of the coal dust during travel of the car especially when the car is travelling at a high rate of speed. Then of course, there is always the wind to be considered if the coal is left uncovered and here again you have coal dust particles being blown away from the coal and this dust is scattered into the surrounding atmosphere causing a pollution problem. Also, there is always the threat of the coal in the car being exposed to the elements such as rain or snow which will thus reduce the efficiency of the coal when the same is fed into a furnace for combustion therein. While the cover is particularly suitable for coal transporting cars, it is equally as effective to cover cars employed for transporting light weight granular materials such as grains or the like.
