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. The method of operation of the device is also described.
