  • Patent number: 4373757
    Abstract: A conveyor trough for a scraper conveyor is used as a way or track for an underground mining machine. The conveyor trough includes a trough base with lateral section members welded thereto along the longitudinal sides and form at each side a V-shaped space that extends from the plane of the trough base to the height of the section member. A lateral section member descends toward the floor at each side of the trough base where it extends to a flange parallel to the mine floor and projects from the lateral section from the lateral section member. The flange has a width and thickness to form a machineway or track. Divering arms at each side of the trough base extend to a flange which projects from the arm to extend parallel to the floor and forms a machineway or track by the width and thickness dimensions thereof.
