  • Patent number: 5934160
    Abstract: A device for removing a cork from a stoppered bottle utilizes a lever and a cam to drive a helical corkscrew into a cork, to withdraw the cork, and then to strip the cork from the corkscrew. The device comprises a housing having a bell-shaped opening to be placed over the mouth of the bottle. A lever has a semi-circular gear at one end which is pivotally joined to the housing. The gear engages a reciprocating, and preferably a rotatable gear rack whereby pivotal movement of the lever causes the gear rack to move linearly up and down through the housing. The lower end of the gear rack is joined to the corkscrew the free end of which extends through a cam collar and engages a cam follower therein. The cam collar is movable vertically within the housing from a lower position to a raised position, but is restricted against rotation relative to the housing. Two or more flexible fingers have notches therein which engage and disengage corresponding projections on the cam collar.

  • Patent number: 5924338
    Abstract: Apparatus comprising a worm (14) that engages with a control nut (9), such that the worm spirals through the nut into the cork (4) on insertion while the nut remains stationary, then the cork is extracted by an upward force on the nut. Mechanical advantage may feature on the insertion and/or extraction processes. Both the upward force and the torque on the worm from the nut are balanced by non-frictional forces from the cork, arising from frictional forces between the bottle (2) and the cork. Having independent insertion and extraction mechanisms enables these mechanisms to be controlled independently and enables the worm to be inserted to and extracted from different depths, depending on the length of the cork. This is not possible in previous nut corkscrews, which rely either on latches at the end of the insertion stroke or on friction between the cork and the worm.

    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.

    Abstract: An improved mechanical cork puller wherein the pivot holes of the lever arms receive and pivot about one or more ribs formed on the inner surfaces of the opposed pairs of support ears, resulting in no visible sign of a pivot support on the outer surfaces of the support ears. The support ears have an inwardly diverging taper providing free meshing movement between the toothed sectors of the lever arms and the cork puller shaft. To manufacture, elongated rib members are initially die-cast on the inner surfaces of the support ears and thereafter cut away to the desired length to form the pivot support for the lever arms. As cast, the inner surfaces of the support ears diverge outwardly and thereafter the outer ends of the support ears are bent toward each other so that the inner surfaces thereof diverge inwardly. The lever arms are thereafter assembled by merely force fitting them into place between the support ears.
