  • Publication number: 20240359650
    Abstract: A grille guard configured to be rotatably attached to a vehicle by a pivot bracket having a first end configured to be attached to a frame of the vehicle and a second end attached to the grille guard. The grille guard is rotatably attached to the frame so as to be movable between an upright configuration where the grille guard extends orthogonally relative to the bumper and a horizontal configuration where the grille guard extends in parallel relative to the bumper. A support assembly including a support member supports the grille guard when the grille guard is in the horizontal configuration.

  • Patent number: 6718868
    Abstract: A peeling device supports a fresh commodity in a first position in a nonspecific orientation. The commodity is impelled using a thruster toward a scoring structure for scoring the peel to a predetermined depth into two sectors. Peel grippers hold the peel between the scores and release the peeled commodity, such that the peel is retained on the gripping means. The thruster is positioned and adapted to force the commodity along a path to engage the cutting and peel-gripping elements, the thruster bottom surface changeable from a first, generally concave orientation for conforming to a shape of the commodity to a second, generally convex orientation for releasing the commodity from the peel.

  • Patent number: 6371014
    Abstract: The system for peeling a fresh commodity includes barbs for piercing the peel in a plurality of spaced-apart locations. A vacuum infuser is used to infuse the pierced commodity with an aqueous solution to loosen the peel. A peeling device supports a fresh commodity in a first position. The commodity is impelled toward a structure having cutting elements for scoring the peel to a predetermined depth. Preferably the scores are made along generally circumferential lines having substantially common endpoints. Peel grippers hold the peel between the scores and release the peeled commodity, such that the peel is retained on the gripping means. A thruster is positioned and adapted to force the commodity along a path to engage the cutting and peel-gripping elements.
