  • Patent number: 10188416
    Abstract: The bifurcated forceps include a first pair of forceps having a first pair of opposed forceps or pincer arms and a second pair of opposed forceps or pincer arms. Each arm has a pivot end and a gripping end. Each pair is coupled at the pivot end and resiliently biased to a spaced apart position at the gripping end so that each pair may be independently pinched together, defining a gripping plane. The pivot ends of the two pairs are rotatable about a common pivot axis in a plane normal to the gripping planes, the arms in each pair being constrained to rotate to an identical radial angle in order to grip the same object at spaced apart positions. Adjacent arms in different pairs may have a mating blade and receptacle configuration to releasably lock the arms together to use the two pairs as a single pair.

  • Patent number: 7794306
    Abstract: An apparatus and method for surface finishing a workpiece is disclosed as including a workpiece supporting mechanism supporting a workpiece having a target shaped periphery with a given width to be surface finished and a tool holder holding a surface finish tool in abutting contact with the target shaped periphery of the workpiece. A pressure applying mechanism is operative to apply a pressure force to the surface finish tool through the tool holder to cause the surface finish tool to be held in pressured contact with the target shaped periphery, with the pressure force exhibiting a given distribution pattern depending upon an axial direction of the workpiece. A drive mechanism rotates the workpiece to allow the surface finish tool to surface finish the target shaped periphery into a given geometrical profile, variably contoured along an axis of the workpiece depending on the given pressure distribution pattern.

  • Patent number: 7237425
    Abstract: The present invention is a hinge repair tool constructed from two, spaced apart pairs of modified vise grip or wrench pliers. A single, elongated, upper bar is connected to the respective top jaws of each of the pairs of pliers. Two lower bars are also connected to respective lower jaws of the two pairs of pliers. Each of the pairs of pliers is operative independently of one another, so that each of the respective lower bars can be repositioned relative to the common upper bar. The lower bars are separated from one another and a gap is formed therebetween. A rigid bar is connected to the handles of the two pairs of pliers to provide additional stability. The vise grip pliers each include a mechanism for locking the lower jaw relative to the upper jaw thereof.

  • Patent number: 6786117
    Abstract: A versatile use pliers which has a first pair of jaws reversely positioned relative to a second pair of jaws. Both pairs of jaws are to be simultaneously movable between an open and a closed position. Movement of the jaws between the open and closed position is accomplished by a handle assembly upon which both sets of jaws are mounted. The handles are pivotable about one-hundred and forty degrees which will remove one set of jaws from an operating position and substitute the other set of jaws in the operating position. The pair of jaws are connected together about a connecting axis arrangement which is separate from and spaced from the pivot axis arrangement for each pair of jaws.

  • Patent number: 5513783
    Abstract: An improved tool for assisting the application of a stocking to a user's leg is provided. The tool includes a pair of curvilinear arms with side rails mounted for lateral pivotal movement in a first plane between a closed position, wherein the side rails are in close proximity for receiving a stocking, and an open position, wherein the side rails are relatively spaced apart to outwardly stretch the stocking for application to the user's leg. An elongated bar having a tongue is mounted to the arms for pivotal movement in a second plane generally perpendicular to the first plane of movement. The tool further includes means operably coupled to the bar for moving the bar in the second plane between a disposition wherein the tongue is in close proximity with the rails when the tool in the closed position, and a disposition wherein the tongue is relatively spaced away from both rails when the tool is in the open position.
