  • Patent number: 4233923
    Abstract: A safety release for water skiing tow lines comprising a U-shaped body having a rearwardly facing slot therein, a mounting bracket for securing the device to a ski pylon, a bolt arm pivotally secured to the body which extends across the slot when the arm is in a vertical position so as to engage the terminal loop of the ski rope. The loop retaining bolt arm is pivotally mounted on the body and is pivotable rearwardly from a first position substantially normal to the plane of the slot opening to a second position substantially free of the slot opening. A manually operable extension is affixed to the bolt arm to move the arm in a forward direction from the second position to the first position. A lever is pivotally mounted on the body to engage the bolt arm to form a bar-like assembly which extends transversely of said opening.

  • Patent number: 4173196
    Abstract: A safety release for water skiing tow lines comprising a U-shaped body having a rearwardly facing slot therein, a mounting bracket for securing the device to a ski pylon, a release arm pivotally secured to the body and including a bolt which extends across the slot when the arm is in a vertical position so as to engage the terminal loop of the ski rope. When the arm is pulled forwardly by means of a trip line operated from within the boat, the bolt is retracted out of the slot thereby releasing the tow line. Adjustable spring biased detents are provided for locking the release handle in the open and closed positions.
