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. Located above the strainer is a rotary valve and below the strainer is a pulp squeezing device, latter being vertically operable in the lower passageway end. The valve is movable to a passage-closed position substantially contemporaneous with the pulp squeezing device moving upward in the passageway, to compress the pulp therein. An orifice of selected size is utilized to provide a degree of inhibition to seeds and peel portions exiting downward through the passageway, thus to determine the amount of pressure existing in the pulp during the ascent of the pulp squeezing device.

A fruit juice extraction machine for squeezing selected amounts of juice from at least one fruit item, said machine comprising at least one pair of cups disposed in a vertically aligned relationship, each of said cups being defined by a series of spaced apart fingers, with the lower of each related pair of cups being defined by a series of spaced, upwardly extending fingers and a centrally disposed fruit piercing means, each upper cup being mounted on a vertically movable member that is movable at selected times between preascertained upper and lower positions, each upper cup being defined by a series of spaced, downwardly extending fingers, the fingers of each said upper cup coinciding with the spaces between the fingers of the respective lower cup, such that an item of fruit received in said lower cup can be squeezed as a consequence of the upper cup descending with its fingers in meshing contact with the fingers of the related lower cup, power means for causing said vertically movable member to undertake recurring movements between the preascertained upper and lower positions, with said upper cup, when said vertically movable member i in said upper position, permitting the insertion of an item of fruit into each said lower fruit receiving cup, and when each said upper cup has been caused to move into the lowered position, it brings about the squeezing of the fruit item caused to reside in the respective lower cup, a passageway extending downwardly away from each said lower cup, through which juice, pulp and seeds are caused to flow from the squeezed fruit as a result of the descent of said upper cup, valve means operatively mounted in an upper portion of said passageway and movable between open and passage-closed positions, strainer means located in a mid part of said passageway, through which only the juice can flow into a surrounding juice-receiving container, pulp squeezing means operatively disposed in a tight fitting manner in a lower part of said passageway, and slidably movable between lowered and raised positions, said valve means being in an open position at the time the juice is being squeezed out of the fruit as a result of the descent of said upper cup, to permit the juice to flow through said passageway and said strainer means into the juice-receiving container, said valve means being moved to a passage-closed position at a time subsequent to the squeezing of the fruit by said upper cup, the movement of said valve means to said passage-closed position being substantially contemporaneous with said pulp squeezing means being caused, in concert with the upward movement of said upper cup, to ascend up through said passageway, to compress the pulp in said passageway residing adjacent said strainer means, and an orifice of selected size located in a lower part of said passageway, to provide a degree of inhibition to the exiting of seeds through the lowermost part of said passageway, thus to determine the amount of pressure built up in the pulp residing in said passageway during the ascent of said pulp squeezing means.
