Abstract: In a pliers-type tool having a stationary first handle and a second handle pivotally movable relative to the first handle, a slidable jaw carrier is movable along a rectilinear guiding track in a body member due to the pivotal movement of the second handle. The first handle is fixed to the body member. The second handle is in engagement with a toggle mechanism including a driver arm which, in turn, is pivotally attached at a stationary location to the body member. When the second handle is pivoted, the driver arm contacts, in a gliding manner, the jaw carrier and moves it rectilinearly in the guiding track. The driver arm extends transversely of the rectilinear guiding direction of the guiding track. Forces acting through the driver arm in the direction transversely of the rectilinear direction of the guiding track are prevented from affecting the movement of the jaw carrier. The second handle can be connected to the first handle by a connecting link.

Abstract: Apparatus for separating individual conductor elements in a multiple-conductor flat ribbon cable including a rotatable cutting element for cutting the insulating sheathing of the cable along each of the score lines running between the individual conductor cores. The cutting element is provided with a plurality of protruding arcuate cutting edges each interrupted by a shorter indrawn non-cutting edge. Further provided is a cable support element adapted to press a cable inserted into the apparatus against the cutting edges, but not against the indrawn edges. When the indrawn edges face the cable support element, a feed-in and feed-out gap is provided for easy insertion and removal of the cable.

Abstract: Apparatus for stripping insulation from electrical conductors which have a circular cross-section includes a stationary stand on which a circular base plate is rotatably mounted. An elongated support unit for the conductor to be stripped is secured to and extends outwardly from the base plate. One or more insulation cutting knives are slidably or pivotally mounted on a mounting member which rotates together with the circular base plate. The number of knives depends on the type of conductor being stripped. Each knife is provided with an actuating device. The actuating device may be stationary or it may rotate at a rate slower than the rate at which the circular base plate rotates so that the associated knife gradually penetrates into and cuts the insulation layer on the conductor so that it can be stripped.

Abstract: A tool for removing insulation from cables includes a handle, a housing rotatably mounted in the handle, and a cutting blade mounted in and projecting out of the housing. A recess is formed in the surface of the housing from which the cutting blade projects. A holder stirrup positioned in the handle, holds the cable in position against the cutting blade.

Abstract: A hand tool for stripping insulation from the end of a wire includes a pair of gripping jaws for holding the wire and a pair of cutting and stripping jaws for removing the insulation. An actuating member is pivotally connected at one end to the cutting and stripping jaws and at the other end to a pivotally mounted driving member. When a pair of handles on the tools are pressed toward one another, the two pair of jaws engage the wire, one pair holding the wire while the other pair cuts and strips the insulation. During this operation, the actuating member displaces the cutting and stripping jaws away from the gripping jaws and pulls the cut insulation at least partly off the end of the wire.

Abstract: A tool particularly suitable for use in crimping includes two arm members and a pair of working jaws each supported on a different one of the arm members. A drive arrangement such as a pair of handles is connected to the arm members for moving the arm members relative to each other between open and closed positions. The drive arrangement, arm members and working jaws provide two force transmitting paths each extending between a different point on the drive arrangement where an external operating force is applied, and a different one of the working jaws whereat the operating force is transferred to an article to be worked on by the tool. At least one pivotal connection is provided, including at least one pivot member and a bearing member for engaging the pivot member. The bearing member is arranged to deform resiliently when the operating force is transferred to the bearing member by the pivot member.

Abstract: A crimping tool includes a pair of arm members and a driving mechanism such as a pair of handles for moving the arm members. An elongated working jaw is mounted on each of the arm members, one of the working jaws having a female die and the other working jaw having a male die arranged thereon. The female die has a notch, and the male die has a base part and an elongated leading face spaced from the base part. A locking mechanism prevents the driving mechanism from returning to an open position before the driving mechanism is brought to a fully closed position. A resilient elastomeric block is provided in the tool to enable the driving mechanism to be brought to the closed position when an article to be crimped is located between the working jaws.

Abstract: A tool for removing solder comprises a tubular body having a nozzle at one end thereof and a piston device arranged to reciprocate within the tubular body to produce a suction effect through the nozzle during a solder removing operation.

Abstract: A device for stripping the insulating sheathing from electrical wire conductors includes a pair of jaws formed of a stack of resilient blades having at least one leg which has an end formed with a cutting projection, the cutting projections being aligned to form a cutting edge when the blades are assembled in a stack to form one of two stripping jaws for the device. The blades of the jaws will exhibit different flexion characteristics depending upon the shape and configuration of the blades which may be in accordance with one of several aspects of the invention.

Abstract: A wire stripper for removing the insulation from single-core or coaxial cable has a pair of elongated jaws which are hinged together at one end and are provided with a latch at the other end so that they can clamp the wire between them. One of the jaws carries a blade, preferably in a replaceable cartridge, adapted to penetrate into part of the periphery of the insulation of the wire while the other jaw is formed with a bed to receive the wire and hold it during penetration by the blade. One of the jaws is also provided with a ring or eye into which the user can insert a finger and thereby twirl the tool around to effect relative rotation of the tool and the wire to cut through the insulation over its entire circumference. The tool is then drawn off the wire axially or the wire is withdrawn axially from the tool to strip the severed length of insulation from the wire. When two axially spaced cuts are to be made, the replaceable cartridge is formed with two blades in parallel transversely spaced relation.
