Abstract
Articles are transferred by an apparatus having a hollowed frame lacking a continuous peripheral wall in which a guide is positioned for slidably containing an open-topped bowl. A hopper connected with a holding plate is positioned within the frame to reciprocate to be fixed to a bowl contained in the guide so that upon rotation of the frame which, in turn, rotates the hopper and holding plate and the guide containing a bowl having a product therein, the bowl in the guide is moved from an upright position to an inverted position. During the rotation, the hopper is covered to contain product and then, upon bowl inversion, the product is released.

An apparatus for transferring products comprising:
- a frame comprising first and second spaced-apart side members, each side member being configured to encompass an opening about a central axis, and comprising a plurality of longitudinally extending connecting members which are spaced apart one from another and extend between and connect the side members so that the first and second side members form first and second frame sides which have an opening disposed about the central axis of each side member and so that the connecting members are disposed between the side members so that the frame has an interior hollowed about a frame central axis coincident with the central axis of each side member and so that the frame has openings between the connecting members;
- means for rotating the frame so that the frame is rotated about the frame central axis disposed horizontally;
- a guide member which extends longitudinally within the interior hollow of the frame from side to side parallel to the frame central axis and is connected to the frame, for slidably containing and guiding an open-topped bowl through the frame interior side to side;
- means for feeding an open-topped bowl to the first frame side and to the guide member so that the bowl is fed to the guide member in an upright open-top position suitable for containing a product therein;
- means for covering and for uncovering an open top of an open-topped bowl contained in the guide member first to fix and then subsequently to release the bowl in and from the guide member and for, upon rotation of the frame, wherein a bowl containing a product therein rotates with the guide member from an upright to an inverted position, containing a product during the rotation and for releasing the contained product when the bowl is in an inverted position;
- and
- means for removing a bowl from a side of the frame.

An article transfer apparatus comprising:
- a frame comprising first and second spaced-apart rings, each ring being configured to encompass an opening about a central ring axis, and comprising a plurality of longitudinally extending connecting bars which are spaced apart one from another and extend between and connect the two rings so that the first and second rings form first and second frame sides which have an opening disposed about the central axis of each ring and so that the connecting bars are disposed between the side members so that the frame has an interior hollowed about a frame central axis coincident with the central axis of each ring and so that the frame has openings between the connecting bars;
- means for rotating the frame so that the frame is rotated about the frame central axis disposed horizontally;
- a guide rail member having a base and spaced-apart guide sides which extends longitudinally within the interior hollow of the frame from side to side parallel to the central axis and is connected to the frame and positioned for slidably containing and guiding an open-topped bowl through the frame interior side to side;
- a hopper extending longitudinally between opposing first and second open hopper ends, a hopper holding plate connected to the hopper and positioned to extend parallel to the guide rail member to position the hopper so that the first hopper open end faces the guide rail, and means connected to the plate and fixed to the frame for moving the holding plate and hopper towards and away from the guide rail member to cover and uncover an open top of a bowl and first to fix and then subsequently to release a bowl in and from the guide rail;
- a cover connected to the frame which is movable for covering and uncovering the hopper second open end so that upon rotation of the frame, wherein a bowl containing a product therein is rotated from an upright to an inverted position, the cover covers the hopper second open end to contain product therein and wherein the cover uncovers the hopper second open end to release the contained product when the bowl is at an inverted position;
- means for moving the cover for slidably covering and uncovering the second open end of the hoppers.

A process for transferring articles comprising:
- introducing an upright open-topped bowl containing a product onto a guide member;
- covering the open top of the bowl introduced with means to fix the bowl to the guide member and with means to contain product contained in the bowl when a bowl containing product is moved from an upright product-containing position to an inverted position and to release product from the bowl when inverted;
- fixing the bowl to the guide member, closing a cover of the means to contain the product and rotating a frame connected to the guide member to rotate the guide member about an axis so that the fixed bowl is moved from an upright position to an inverted position;
- opening the cover of the means to contain the product to release product from the containing means;
- rotating the frame to rotate the guide member about the axis from the inverted position to an upright position;
- and
- releasing and removing the empty bowl from the guide.
