  • Patent number: 4951563
    Abstract: An automatic juice extraction machine for squeezing juice from one or more pieces of fruit in accordance with this invention comprises at least one pair of cups disposed in a vertically aligned relationship, with the lower of each related pair of cups utilizing a series of spaced, upwardly extending fingers and a centrally disposed fruit piercing tube. This tube defines part of a passageway located directly below each lower cup, in which passageway a strainer is disposed. Each upper cup, defined by spaced, downwardly extending fingers, is mounted on a vertically movable member movable between spaced vertical positions. The spacing of the fingers allows the fingers of the upper and lower cups to mesh, to bring about squeezing of the fruit. We utilize a pneumatic device for causing a single piece of fruit to be inserted into each lower cup subsequent to the raising of the vertically movable member.
