HOPPER DEVICE FOR MATERIAL SPREADER Abstract of the Disclosure A hopper device for mounting transversely across the ma- terial discharge end of a vehicle mounted dump bed adapted to contain particulate material to be spread over a roadway being travelled by the vehicle. This type of hopper includes fixed first and second spaced end walls, a fixed back wall between the end walls and an elongated auger extending between the end walls, and an arrangement for rotating the auger about an axis to move material through the hopper toward one end of the hopper. This type of hopper generally includes a cover member extending between the end walls and movable between a spreading position where the material can dump into the hopper and be spread from the hopper, a dumping position where the material can be dumped over the hopper and a cleaning position where access is possible to the auger for cleaning by a water hose. In accordance with this in- vention, the cover member is mounted on links that coact with the end plates to hold the cover plate in each of the three inde- pendent positions without losing control of the movement of the cover member between these positions.
