Foil cutting cork extractor

摘要

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about a longitudinal rotation axis coaxially aligned with a location of a bottle neck from which a corkscrew is to be withdrawn.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.

1. A cork extracting machine comprising in combination,
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 coupled through a freely rotating connection to the vertically translating driver wherein the worm freely rotates about a longitudinal rotation axis coaxially aligned with a location of a bottle neck from which the cork is to be extracted; a crank rotating the pinion gear for translating the driver up and down relative to the shaft along the rotation axis of the helical worm; a non-rotating cam releasably coupled between the vertically translating driver and an annular collar assembly receiving and following the helical worm for imparting torque rotating the worm; and a helical pinion rack affixed to the gear rack drives a helical pinion gear to rotate about the longitudinal rotation axis in meshing engagement with helical pinion 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.
