  • Publication number: 20040134315
    Abstract: A pair of manual tongs comprising two limbs which are rotatably connected in a common first rotational axis. The first limb is separated into two levers in its lever section, the two levers being rotatably connected in a first articulation, in a second rotational axis parallel to the common first rotational axis. A means of traction connects the second limb to the lever of the first limb, which is situated at a distance from the handle. The means of traction can be shortened by means of a pivotal movement of the lever of the first limb, which is situated close to the handle, above the second rotational axis. The areas of use of the manual tongs are often difficult to access. According to the invention, the second limb of the inventive manual tongs is thus separated into a lever situated at a distance from the handle and a lever situated close to the handle and the two levers are rotatably connected in a second articulation, in a third rotational axis which is parallel to the common first rotational axis.

  • Patent number: 6128943
    Abstract: The present invention is an adjustment mechanism for both hand and production tools of any capacity. An eccentric pin mechanism provides the pivot between two handles or other load transferring members. The rotation of the pin moves the two members closer or farther apart, indirectly controlling the final position of the blades or jaws. This adjustment can be used to compensate for wear or to provide adjustment for a specific use. The eccentric pin is locked into position by means of a pressure pin mechanism. For light duty tools, this pressure pin mechanism would consist of a spring loaded pin which resists rotation of the eccentric pin during normal operation of the tool. The spring loaded pin would allow rotation of the eccentric pin when a tool is used to rotate it. For heavy duty applications, the pressure pin mechanism would consist of a solid set screw.

  • Patent number: 4748876
    Abstract: Prior universal pliers with two gripping arms (11, 15) and an adjustable jaw have the disadvantage that during adjustment one must change hands while using the pliers which is unfavourable as regards the economic requirements. This disadvantage is obviated by the present invention in that both gripping arms (11, 15) are non-displaceably articulated on one another and one of the two jaws (19) is displaceably mounted with respect to its associated gripping arm (15) at right angles to the jaw opening.
