  • Patent number: 4936204
    Abstract: A citrus fruit segmenter which uses a slicing lever mounted with a blade which is attached to the sidewalls of a frame by another pair of levers. The slicing lever with the blade nudges a resiliently biased crank lever which intermittently rotates a ratchet wheel upon which a cup is mounted to carry a half of grapefruit or large orange. The crank lever has a tooth element designed to engage the toothed ratchet wheel and to retract when working against a locking pawl. The tooth element is also resiliently biased. The resilient biasing of the crank lever and the toothed element are accomplished by corrosion-resistant "O" rings. All of the elements of the device are made of corrosion-resistant material. The blade is made of stainless steel, the frame and levers are made of synthetic resinous material.
