Abstract
Corkscrew machine including rotatable spiral radius pinion gear mechanically coupled to annular collar and engages inclined gear rack to translate driver up and down carrying freely rotating, helical corkscrew. Crank rotates spiral radius pinion gear to translate driver up and down relative to collar along rotation axis of corkscrew with mechanical advantage increasing as driver approaches collar. A non-rotating collar cam coupled to, translated relative to, driver, receives and follows helix of corkscrew to impart torque rotating the corkscrew when held stationary within annular collar responsive to translation of driver toward and away from annular collar. Biased, releasable collar latch captures and holds collar cam at stationary position within annular collar releasing it to translate upward with driver upon an upward cork pulling stroke of driver relative to collar when bottle is held within annular collar.
