  • Patent number: 4407337
    Abstract: A wire wrapping tool comprises a head which is formed integrally with a shaft. The head includes a frusto-conical portion which has a chordally extending portion cut away to define a cutting edge. A blade portion is formed on the head, the blade having a slot through which a wire can pass. The head also has an axially extending bore into which a wire wrapping post can be inserted. In use the shaft is attached to a pistol gun to rotate the head. Wire from which the insulation is to be stripped is passed over the edge, through the slot and around a wrapping post. As the wire passes over the edge a longitudinal slit is formed in the insulation which is then stripped away from the conductive core as the wire passes through the slot.

  • Patent number: 4380111
    Abstract: A combination bit for cutting and stripping insulation from a solid flexible conductor wire and wrapping a stripped end portion of the wire on a terminal in a series of helical convolutions includes a cooperable sleeve having a wall portion forming a guide surface for permitting insertion of the wire into a groove formed on the periphery of the bit. A cutting blade disposed in the groove includes opposed straight cutting edge portions one of which is proportioned such that it engages the insulation of the conductor wire initially in a position which places said edge parallel to a cooperative flat surface portion on said sleeve and tangent to the circumference of the wire insulation. The bit and sleeve are proportioned so as to provide for initial engagement of the insulation by the conductor wire within approximately five degrees of angular rotation of the bit from its starting point.

    Abstract: The wire cutting, skinning and wrapping tool includes a hollow sleeve, a knife carried by the sleeve, a bit provided with a longitudinal groove which is able to slide in a forward and backward direction in the sleeve, the bit and the knife skinning an insulated wire over a predetermined length and a means to move the bit from a backward to a forward position during the skinning operation. The sleeve is provided by normally closed sleeve halves with the insulated wire opening the sleeve halves during the skinning operation and with the sleeve halves closing again when the bit is in the forward position after each skinning operation. The length of skinned wire is captured between the bit groove and the closed sleeve halves.

    Abstract: A tool for attaching a wire dropper or batten to the wires of a fence line comprises a body having first and second wire engagement devices which are located at substantially right angles to one another. The body includes a lever mounting device which can receive a lever for operating the tool. The tool is used by engaging a fence wire in the first wire engagement device and the wire dropper or batten in the second wire engagement device. The body is then rotated about an axis which is coaxial or parallel with the longitudinal axis of the fence wire so as to wind the wire dropper or batten onto the fence wire.

  • Patent number: 4331182
    Abstract: The present disclosure describes a dressing finger assembly of advanced design for use on automatic wiring machines. Such machines make solderless wrapped electrical connections on pluralities of planar disposed terminals. A dressing finger is employed to form predetermined wire patterns in conjunction with a wrap tool which makes the actual connection. It has been observed that the design of dressing fingers used in present day machines is such that the insulation of the wire being wrapped may be pinched and cut, thereby necessitating its replacement to avoid electrical shorting. In accordance with the present invention, the assembly comprised of a newly designed finger and supporting guide, provide the required retention and support of the wire during wrapping while eliminating the aforementioned damage to the wire.

  • Patent number: 4329777
    Abstract: An improved tool for wrapping wire around an electrical terminal to make an electrical connection. The tool includes a bit and a sleeve for receiving the bit. One end of the bit has a connecting member for coupling the bit to the chuck of a hand-held drive motor. The opposite end of the bit is provided with a tip having a recess axially aligned with an axially extending groove formed in one side of the main body of the bit. A discontinuity between the recess and the groove is defined by a ridge having a pair of relatively convergent edges which extend toward the axis of the bit and terminate at a notch axially aligned with the bottom of the groove in the bit body. A crescent-shaped projection extends axially outwardly from one side of the tip to wrap the end of the wire against the terminal. The sleeve has an enlargement at the end near the tip for receiving one end of a wire and guiding it to the groove and outwardly through a side window in the sleeve before rotating the bit.

  • Patent number: 4330093
    Abstract: In the wire-wrapping of terminals which extend from a terminal block, an operator uses a hand tool which includes a housing having a bit that wraps a wire-like conductor about each terminal, and a handle which allows the tool to be held in a modified prehensile manner. The handle is configured to include a laterally disposed thumb rest which is effective to support the thumb in a relaxed position. The surface of the rest which supports the thumb includes a port which is covered and uncovered repetitively by relatively slight movements of portions of the thumb to control the operation of a fluidic circuit to turn the bit and cause the conductor to be about the terminal. This arrangement results in a substantial reduction in the movement of particular joints of the thumb and of particular muscles which control the movement of the thumb so that worker fatigue is substantially reduced.

  • Patent number: 4287666
    Abstract: The present disclosure describes a side-loading wire wrapping assembly comprised of a specially configured bit and sleeve, for use on semi-automatic wiring machines. Such machines are used to make solderless wrapped connections on terminals emanating from a common plane. The wire wrapping assembly in present use on many of such machines consists of a fixed sleeve substantially enclosing a spring-loaded bit. The arrangement necessitates front-loading of the bit by the operator--a procedure which is tedious and time consuming. The present invention obviates these difficulties by converting the fixed-sleeve assembly from front-loading to side-loading. This is accomplished by providing in the sleeve, a wire feed aperture in contiguity with a longitudinal slot and of orienting the former with a widened portion of the slit formed in the bit periphery by the wire receiving bore.

  • Patent number: 4205543
    Abstract: A spring winder includes a base and a mandrel rotatably held against the base by a pair of mounting blocks which include aligned grooves in which the mandrel is seated. Each block is connected to the base by a pair of mounting screws which cooperate with associated compression springs for resiliently holding the mandrel between the mounting blocks and the base with a variable force. A length of spring wire is fed between a cam and washer rotatably mounted on the side of the base by means of an adjustment screw, the wire then being fed through an aperture in the adjacent end of the mandrel. The cam and washer are resiliently urged together by a compression spring for applying a drag to the wire which is variable by adjustment of the associated screw. A pin on the washer rides in a complementary groove in the cam for retaining the wire in position. As the mandrel is rotated the wire is wound thereon against the drag of the cam and washer to form a series of helical coils.

The locking mechanism is mounted on the stationary sleeve of the device, and is actuated to responsively effect the release of the bit for rotation, prior to each successive wire wrap operation, only upon a terminal to be wire wrapped being inserted to a predetermined, but adjustable, depth within a terminal-receiving recess formed in the forward end of the bit. Such a mode of operation insures that each wire wrap is accurately positioned on each successive terminal. The bit-locking mechanism also may be optionally employed to responsively actuate an associated switch to either directly, or conditionally (i.e., in conjunction with the actuation of a power source-connected trigger switch), effect the energization of the drive motor coupled to the bit of a wire wrapping device.
