  • Patent number: 3952488
    Abstract: A fruit picker positions a fixed and a movable jaw on a pole-like handle and encloses a majority of the jaw area with an open top fabric bag. Springs are provided normally urging the jaws toward or away from one another and act to hold the uppermost portion of the fabric bag in open position at all times. An actuating cord extends downwardly along the pole-like handle for manual operation of the device. An adjustable stop limits the degree of closure of the jaws to avoid clamping engagement on a limb or a twig.
