Abstract
A corkscrew includes a rotatable pinion gear having a fixed radius and a horizontal rotational axis rotatably coupled to a shaft and engaging a gear rack of a vertically translating driver. A helical worm is coupled through a freely rotating connection to the vertically translating driver wherein the corkscrew freely rotates about a longitudinal rotation axis coaxially aligned with a location of a bottle neck from which a corkscrew is to be withdrawn. A crank rotates the pinion gear for translating the driver up and down relative to the shaft along the rotation axis of the corkscrew. A helical pinion gear a helical pinion rack drives rotates about the longitudinal rotation axis in meshing engagement with helical rack on the vertically translating driver, the helical pinion gear having at least one blade to contact the bottle neck scoring a foil capsule thereon as the helical pinion gear rotates.
