ABSTRACT:
The present invention is directed to a hopper cover having a pair of covering members and mechanism for moving each of the covering members toward and away from the other. Stops ultimately prevent the covering members from falling from the hopper, while mating mechanism and elastic straps combine to hold the covers together when they are moved together. The cover provides a wide central space for filling a hopper, while functioning simply to open and close and provide the necessary protective covering for the substance filled within the hopper.
