  • Cable-suspended draw-curtain system
    Patent number: 4091857
    Abstract: A system is provided whereby a flexible curtain is hunt from a horizontal span of an overhead suspended cable, and can be drawn off said cable onto a rigid track for storage. The track is positioned contiguous to an end of said span and above said cable. Transfer of the curtain from the cable to the track is facilitated by use of an inclined member which smoothly engages both said cable and said track, causing said transfer to occur within said horizontal span. Traversal of the curtain with respect to the cable is achieved by means of carriers equipped with wheels which ride atop said cable.
