  • Patent number: 4222219
    Abstract: A fruit picking panel with a certain arrangement of a plurality of parallel disposed rotating spindles and a certain arrangement of a plurality of intermingled parallel disposed stationary spindles. Both the rotating and stationary spindles penetrate the branches of a fruit bearing tree. Each of the rotating spindles is equipped with a plurality of angularly disposed adjoining shank sections lying out of the axis of rotation and including one portion thereof which is covered with an elastomer that includes as an integral portion thereof a paddle-like radial extension. When the rotating spindles on the fruit picking panel are rotated, the elastomer covered angular portions of each spindle moves toward and away from adjacent rotating and stationary spindles. When the elastomer covered sections of adjacent spindles pass each other they create a scissors action so that intermediately disposed fruit is safely and effectively sheared from its tree attachment.
