  • Patent number: 6343421
    Abstract: A cutting utensil is disclosed as including a wooden handle and a metal blade projecting outwardly from the handle. The handle includes a blade-receiving slot and an outer edge that circumscribes the slot and extends along the outer surface of the handle. The blade is partly received within the slot, and the outer edge of the handle is spaced from the blade to define a gap therebetween. The gap is filled with a synthetic resin material that bonds to the blade and handle. There consequently is no exposed metal-wood interface on the utensil, thereby eliminating the cracks and cavities normally associated with such an interface.

  • Patent number: 6315654
    Abstract: A tripes cleaning apparatus having a suspended, rotatable drum that presents an outer cylindrical surface on which the tripes are supported. The drum includes sets of flighting so as to facilitate arrangement of the tripes on each portion thereof in a single-layered helical orientation. A nozzle is associated with each set of flighting so that a low pressure cleaning fluid can be flushed through the tripes as the drum is rotated. Each nozzle is preferably activated to disperse cleaning fluid by bending the nozzle relative to its normally straight configuration, and a J-hook projects from the drum adjacent each nozzle to releasably hold the nozzle in the open, bent configuration and help retain the tripes against the drum. The apparatus further includes a spray bar operable to clean the outside of the tripes.

  • Patent number: 6082559
    Abstract: A utensil holder generally includes a case and a utensil-retaining rod assembly. The case presents a utensil-receiving opening, and the rod assembly includes a plurality of elongated, flexible rods. The rods are confined within the utensil-receiving opening in a manner that permits limited flexing movement of the rods, whereby a utensil inserted into the opening causes elastic displacement of adjacent ones of the rods to define a space that at least substantially collapses when the utensil is removed from the opening. This permits the utensil to be supported virtually anywhere within the opening. In addition, the rods are sufficiently packed within the opening to support the utensil in the desired orientation. Moreover, the rods are restricted against lengthwise shifting relative to one another, which permits the rod assembly to be unitarily disassembled from the case, if desired.
