  • Patent number: 4025118
    Abstract: A spill-plate housing extends along one side of the course of travel by a mining machine. A flexible cutter cable and water conduit are carried from the mining machine by a carrier arm for extending into the spill-plate housing by projecting through a longitudinal slot formed in a faceplate of the housing. Upper and lower resilient apron strips are secured to the faceplate so that their longitudinal edges abut along the longitudinal center of the slot. Vertical support pipes are secured to the faceplate by upper and lower members to form an internal housing space adapted to accommodate the cable and conduit while coupled to the mining machine. Bias blocking arms are pivotally supported by the faceplate within the housing to prevent unintentional emergence of the cable from the slot in the housing. Pipe-engaging surfaces on clamp plates arranged at opposed sides of the vertical support pipes are used to carry a door for vertical movement to expose the interior of the housing space.
