  • Patent number: 6009583
    Abstract: A pliers-knife combination tool including pivotally connected elongated members. A working region of the tool includes opposed gripping jaws on interior faces of the elongated members and at least one knife edge on an exterior edge of one of the elongated members. Engaging the opposed gripping jaws with each other allow use of the tool as a knife. A method of fabricating the tool includes maximizing the size of the tool for a given size forming machine. Each member is formed separately from the other member to permit sizes as large as possible for the forming dies and machines used. The members are pivotally connected after forming to produce a larger size tool than if both the first and second members were simultaneously formed in a given size forming machine.

  • Patent number: 5996447
    Abstract: A wrench for engaging a faucet mounting nut, the wrench including an elongated tubular pipe which has slots at one end. A nut engaging socket, having radially projecting studs, is adapted for reversible insertion into the pipe opening, with the socket studs engaging the slots in the pipe. A variety of socket inserts, for engagement of a variety of nut sizes and shapes, is provided. Openings in the pipe, at the end opposite the socket engaging end, provide a means for a rod to be inserted into the pipe to facilitate pipe rotation. The elongated pipe, since it is hollow, can slide over a water supply line during mounting nut removal, thereby eliminating the requirement of first detaching the supply line.

  • Patent number: 5960681
    Abstract: A socket driver, and method of forming the same, is described in which longitudinal protuberances are provided on successive surfaces of the hexagonal cavity for receiving a bit driver. The protuberances create an interference fit with the driven end of the bit driver, the protuberances being so dimensioned that forceful insertion of the bit driver into the hexagonal cavity at least partially deflects the walls portions on which protuberances are formed to thereby slightly deflect the same. The resulting restoring forces create a spring action which semi-permanently secures the bit driver received within the socket driver.

  • Patent number: 5960679
    Abstract: A ratcheting, open-end wrench concurrently engages more than half the corners of a nub during torquing. In preferred embodiments a wrench has a contacting cavity for receiving and torquing a nut, bolt head or other angularized nub. A chain carries a plurality of teeth about the inner perimeter of the cavity, and the chain is ratcheted so that the teeth move readily in one direction, but can be blocked from moving in the opposite direction. The teeth are arranged on the chain such that the cavity changes shape from an open configuration in which the nub can be received into the cavity, and a closed configuration in which the nub is locked into the cavity.

  • Patent number: 5953966
    Abstract: A hand held torque wrench with augmenting means is provided which includes a linkage assembly to join a drive input with an output wrench socket. The linkage assembly consists of a drive link extending from the input socket and coacting with a conversion link extending to a ratchet disposed about the output socket of the device. Rotation of the drive link pivots the conversion link to transfer torque from the input to the output socket. A pawl on the driven link is provided to coact with a ratchet which encircles the output socket. A guide means is disposed in the interior of the housing of the device to coact with the linkage assembly to maintain proper alignment during a torque operation, such that stress and force are substantially reduced or dissipated, if not eliminated, during the operation.

  • Patent number: 5951376
    Abstract: For two-side processing of optical lenses, the invention provides that blanks to be used for each lens body (7) comprise a chucking extension (18) whereby a single machine is sufficient for implementing the procedure. In addition to workpiece spindles (1, 2) as well as tool spindles (4, 5) with coarse tools (8) and finishing tools (9), the machine also includes an unloading device (10) and a loading device (13) which in successive interacting operations take the lens body (7) when processed on one side and at the circumference from a chucking tool (12) of the tool spindle (1) and turn it round for centered insertion in its inverted position into a chucking tool (15) of the tool spindle (2) for processing on the other side. The workpiece spindles (1, 2) may be mounted parallel to each other on a horizontally displaceable and vertically adjustable feed slide (3). A feed carriage (6) may displace and slew the tool spindles (4, 5) together with the unloading device (10) around a horizontal B axis.
