  • Patent number: 5161671
    Abstract: A transfer station for transfer of material from a longwall face to the gate or roadway employs a box frame uniting a scraper-chain face conveyor with a scraper-chain gate or roadway conveyor. An opening in the tray of the face conveyor inside the box frame allows material to pass from the top run of the face conveyor to the top run of the gate conveyor. A plate like pivotal supporting element is mounted so as to be adjustable from a stowage position into a set out position and vice versa. In the set out position the support element bridges over the opening in the tray and therefore prevents a collision between the scraper-chain assemblies of the face and gate conveyors during the return of the face conveyor.
