  • Patent number: 6526857
    Abstract: A manually operated modified bolt cutter is placed in a fixture supporting a bolt cutter in a reversed operating position allowing the operator to cut small dimension materials using a one hand or arm pushing motion instead of the two hand or arm compression motion. The fixture holding the bolt cutter is fixedly mounted on a bench or like support and has two upright members between which is held one handle of the bolt cutter. Bolts through the side members and one handle support the bolt cutter in the fixture. When the moveable handle is in a near vertical position the jaws of the cutter are open. When the moveable handle is pushed away from the operator, toward the rear of the cutter, the jaws close making the cut. The moveable handle is bent at an angle to decrease the operator's wrist to arm angle.

The support shaft extends through the through hole of the first cutting blade and the insertion hole of the second cutting blade, for pivotally connecting the first cutting blade and the second cutting blade in a manner such that the first cutting blade and the second cutting blade can perform relative rotation about the support shaft with respect to each other to thereby perform a cutting operation. The second cutting blade has a spring nut portion formed in the form of a spring nut on an inner peripheral surface of the insertion hole.

  • Patent number: 6305088
    Abstract: A pair of scissor blades illustrated in (FIG. 4); each blade comprising a cutting edge (3) arranged below a blade protuberance relative to the direction of the cutting stroke. The protuberance comprises a cutting edge grinding surface (4), a pressing ridge (5) and a blade side surface (6). The protuberance presses on skin creating sensitive reactions in the user prior to the rear located cutting edge damaging the skin. The cutting edge degree of sharpness is predetermined at the factory. A method of manufacturing the invention and for modifying standard prior art scissor blade shapes by grinding a cutting edge at a new angle of sharpness that inherently produces the safeguarding blade protuberance.

    Abstract: A pair of hairdressing scissors comprises first and second scissor elements pivotally connected together, each scissor element including a blade portion. The blade portion of the second scissor element has a cutting edge. The blade portion of the first scissor element includes a plurality of teeth that are spaced by an interval. Each tooth on the second scissor element includes a distal end having a first side that faces the cutting edge of the first scissor element and a second side that faces away from the cutting edge. The first side of the distal end of each tooth includes a distal first guide face and a second guide face extended from the distal first guide face. The distal first guide face has a slope smaller than that of the second guide face. The second guide face includes a cutting edge that cooperates with the cutting edge of the second scissor element for cutting hair. A distal beveled face and a third guide face are formed between the first side and the second side of the distal end.

  • Patent number: 6264669
    Abstract: Instruments including a pair of scissors (1) for removing the bump from an aquiline nose, wherein the scissors have cutting blades (5,6) with mutually facing concave cutting edges (7,8) matching the shape of the bump, as well as a clamp with two cutting blades each having a double curvature in two perpendicular planes so that the clamp fits the lateral bones of the nose. The clamp enables lateral osteotomy of the nose once the bump has been removed by means of the scissors (1), whereby the surgeon can reconstruct the shape and profile of the nose. The number of instruments needed may thus be reduced considerably relative to the prior art, while the reliability, accuracy and safety of the operation may be substantially enhanced.

  • Patent number: 6260462
    Abstract: Cartons of the type used for domestic milk supply may be more readily opened if a portion of the ridge that extends above the wings of the carton is first severed between the wings and the heat sealed closure so that the severed portion of the ridge may be folded back from above the wings or removed by a further cut across the ridge to the first line of sever. The wings are then free to be folded back and pressed inward to open the carton to form a pouring lip. A device for opening cartons comprises a thin blade secured to a handle and hinged within a shrouded recess in a two-part housing. Handles act about the double action hinge to move the blade across the slot to sever a portion of the carton ridge positioned in the slot. A tongue (not shown) holds the device in alignment with the ridge to ensure that the severing is below the sealed portion of the ridge.

    Abstract: A locking mechanism for scissors-type shear allows closing and locking of the shear even when the locking element is placed in a locked position before the shears are closed. The shear includes first and second blade assemblies pivotably connected to one another. Each blade assembly includes a blade and a handle. A locking mechanism is slidably mounted on a first handle. The locking element is moveable between locked and unlocked positions. In the locked position, the sliding lock mechanism engages a catch element on the second handle to lock the shear in the closed position. The locking mechanism includes resilient arms and the catch element includes inclined cam surfaces. When the locking mechanism is placed in a locked position before the shear is closed, the ends of the resilient arms engage the inclined surfaces of the catch element, allowing the resilient arms to flew outwardly and pass over the catch elements.
