  • Patent number: 4934877
    Abstract: A gate for attachment to the hopper of a railway car or other vehicle which carries particulate material. The gate has a pair of sloping walls with facing surfaces, and the lower ends of the walls are spaced apart to permit the particulate material to be discharged into a trough below the spaced ends from which the particulate material is removed by a vacuum hose. A pair of separately operable, rotatable valves of arcuate cross-section are disposed at the space between the ends of the walls to block or permit particulate material flow into the trough. Pneumatically operable agitators are mounted on the walls to prevent bridging of the space between the wall ends of the material during removal thereof.
