  • Patent number: 5280697
    Abstract: The fruit picker separates a fruit, positioned within an intake end opening of a hollow tube, from its stem by extending a blade across the opening. With the stem forced against the wall of the opening, the tube is moved to separate the stem from the fruit. The movement causes the fruit to fall by gravity inside the tube through a discharge end to which a collection bottle is connected.

  • Patent number: 4759174
    Abstract: A vegetable harvesting apparatus which is characterized by a generally triangular-shaped hopper having a cutting opening provided therein, a blade slidably mounted in the hopper and a handle attached to the opposite end of the hopper from the cutting opening, with a pivoting lever mounted in the handle and a blade rod connecting the upper end of the pivoting lever to the blade. The vegetable harvesting apparatus is utilized by extending a vegetable such as a pod of okra through the opening in the front portion of the hopper and forcing the blade against the pod stem by manipulating the rod lever with the hand, to sever the stem and collect the okra pod in the hopper.

  • Patent number: 4608813
    Abstract: An apparatus for picking fruit having an elongated pole attached to upper and lower portions that are removably coupled to each other. Each portion of the apparatus has a metal mounting sheet with a wire container attached to it. The upper mounting sheet of the upper portion has a guide channel groove used for guiding the stem of a piece of fruit to be picked to a position near a first cutting blade located at the bottom of the groove. A guide arm slidably engages two positioning guides attached to the upper mounting sheet. When a cord attached to the end of the guide arm is pulled, a second cutting blade attached near the top of the guide arm moves from an upper position to a lower position proximate the first cutting blade at the bottom of the guide channel groove. As the blades come together, they sever the stem of each piece of fruit to be picked. A spring is used to return the guide arm to its upper position. The guide arm and spring are coupled by a protective shield.

  • Patent number: 4463545
    Abstract: An improved apparatus for picking fruit by severing the fruit from an associated stem is disclosed. The apparatus includes an elongate handle for handling and extending the apparatus to reach the fruit. An elongate bracket bar is fastened to the extended end of the handle. A cutting blade is formed at the uppermost end of the bracket bar. A guide-arm is slidably coupled to the bracket bar. A toothed guide-head is attached to the uppermost end of the guide-arm and includes an upper tooth and a spaced lower tooth which define a stem channel through which the stem of the fruit is guided. The sliding action of the guide-arm is controlled by a raising string which elevates the guide-arm to an extending position, and a lowering string which returns the guide-arm to a retracted position. As the guide-arm, hence the fruit positioned in the stem channel, is lowered, the stem contacts the cutting blade of the bracket bar, which results in the severing of the fruit from the associated stem.

  • Patent number: 4191008
    Abstract: An apparatus for harvesting okra or other fruit or vegetable comprises an elongated frame having a handle at one end thereof and a cutter member at the other end. In order to prevent any contact between the user and irritating pods of the okra, a trigger is provided at the handle for remotely operating the cutter. Also, a shroud partially surrounds the handle to protect the hand of the user during cutting. In one embodiment, the cutter comprises a razor blade located beneath a cylindrical guide member that retains the okra pod in position for cutting of the stem while a pair of stabilizing ears steadies the guide member on a branch of the okra plant. In a second embodiment, a rectangular guide member contains a stem holding bracket that maintains the stem of the okra pod in proper position for cutting by a blade. A set of prongs carried by the blade pierces the pod during a cutting stroke. The pod is automatically released during retraction for disposal into a collection receptacle.
