  • Patent number: 5868044
    Abstract: A stopper remover for a wine bottle, providing a movable and a fixed U-shaped jaws. The fixed jaw develops leverage against the sloping surface of the neck of the bottle while the movable jaw engages the stopper. A screw develops mechanical advantage for separating the jaws to pull the cork. The movable jaw is easily replaceable with a jaw of alternate configuration so that the device is useful for a range of stopper types. A return spring is used to allow the movable jaw to be reset more easily. A set of chamfers are positioned on the movable and fixed jaws to force the stopper to a central desired position on the movable jaw and the fixed jaw to a central desired position on the bottle. A stopper catcher is positioned so that the stopper cannot fly off.
