  • Publication number: 20110244766
    Abstract: An electric sharpener having two pairs of interlocking abrasives for sharpening the edge of blades to different sharpening angles. An adjustment assembly simultaneously moves the wheels of each pair either toward or away from each other to adjust the sharpening angle produced by pair of abrasive wheels in a sharpening operation. The adjustment assembly is provided with a rotatable shaft having an external handle which engages a lower platen. The lower end of the shaft is threaded to move the platen in vertical direction to move translation bars affixed to the platen. The translation bars extend through elongated slots in respective pairs of adjustment arms coupled to each pair of abrasive wheels to rotate and vary the spacing between the abrasive wheels and adjust sharpening angles.

  • Publication number: 20110017853
    Abstract: A device and method for manufacture thereof having a one or more cantilevered cutting teeth integrally formed in raised configuration on a flat base fro cutting food items moved along said base. The free end portion is formed by upper and lower etched out portions of the upper end of said cutting teeth to form a cutting edge. The upper surface of the upper cut-out portion of the teeth is situation at a position out contact with food items being cut. A substantially portion of the teeth is coated with a low friction material, except for the cutting edge In a second embodiment one or more domed cutting elements are cut out of base sheet and may include a leading V-shaped cutting edge.

  • Publication number: 20100162869
    Abstract: A mandoline for cutting and/or slicing food items having an infeed deck and outfeed deck pivotally mounted on a housing adjacent each other in a sloped longitudinal orientation. Adjacent end portions of the infeed deck and outfeed deck are vertically spaced. The end portion of said outfeed deck includes a fixed blade mounted above the end portion of said infeed deck. A pair of knob assemblies are rotatably mounted on opposite sides of the housing and each include a pair of open cam slots and respectively engage a pin respectively formed on opposite sides of said infeed deck and said outfeed deck. Rotation of said cam assemblies causes said infeed deck and outfeed deck to move simultaneously either toward or away from each other to vary the space between the fixed blade and said infeed deck.

  • Patent number: 7703176
    Abstract: The present invention comprises a hinge device. The hinge device is located within a housing, and may comprise a rotating drum mounted on a hinge bar. The rotating drum is slidable between a first, locked position and a second, unlocked position, and also rotatable with respect to the housing. The hinge device may also comprise a engagement wall positioned within the housing and having a shelf and at least one locking slot. A locking member may be formed on the rotating drum and may cooperate with the engagement wall when the rotating drum is in the first, locked position to prevent the rotating drum from rotating with respect to the housing. A biasing spring may be located within the housing, which biases the rotating drum toward the first, locked position.

  • Publication number: 20100012758
    Abstract: A kitchen utensil, in the nature of a zester (15), having a zester blade (17) on which an array of teeth are formed. The blade (17) is fashioned out of a blank of thin metallic material, the edges of which are quite sharp. At least two such edges intersect to create a very sharp point and which becomes an area of potential injury. To minimize injury at that intersection, and further, to protect counter tops and the like from marring and scratching, a-protective tip (40) is fitted over that intersection. The protective tip (40) is made out of a soft plastic or rubber material and inhibits contact with the point at that intersection and the area immediately adjacent thereto.

  • Publication number: 20090298401
    Abstract: An abrasive sharpener having a housing supporting a pair of sharpening slots having abrasive elements mounted therein. The bottom of the housing is formed with an open V-shaped groove for supporting the housing on the edge of a table, bench and the like. The bottom further includes a pair of flat bottom surfaces separated by the V-shaped groove for supporting the housing on a flat surface. The V-shaped groove is opened ended and extends along an axis generally perpendicular to the direction that a knife edge and the like is pulled through either slot for sharpening.
