Abstract:
A specialty tool to aid in twisting of up to six (6) individual wires for a cable assembly is herein disclosed, comprising a series of six (6) parallel channels perpendicular to the fulcrum line of the pliers. Each channel is sized to hold one (1) individual wire, facilitated by a one-way fixture that slightly penetrates the wires insulation thus holding it securely. Once the wires are in the tool, the jaws can be locked together and can be rotated in either direction to twist the wires. This procedure would be used with cable assembly during manufacturing processes.

Description:
RELATED APPLICATIONS 
     The present invention was first described in a notarized Official Record of Invention on Sep. 7, 2007, that is on file at the offices of Montgomery Patent and Design, LLC, the entire disclosures of which are incorporated herein by reference. 
     FIELD OF THE INVENTION 
     The present invention relates generally to the manipulation of wires and cable assemblies, and more particularly, to a specialty device to aid the twisting or separation of up to six (6) individual wires for a cable assembly. 
     BACKGROUND OF THE INVENTION 
     The field of electrical devices and systems, and in particular the design, arrangement, and manipulation of electrical wires and cable assemblies, is of great importance in the modern world. The twisting of multiple wires into cable assemblies and the corresponding separation of those cable assemblies into its constituent wires are important processes in this field of work. While these processes may be accomplished through a variety of means, including the use of the hands, dealing with such assemblies can be dangerous, difficult, and time consuming. This disadvantage is especially apparent in cases where the desired work area is difficult to access in some manner. 
     Various attempts have been made to provide for a means to more efficiently work with cable assemblies or a plurality of wires simultaneously. Examples of these attempts can be seen by reference to several U.S. patents. U.S. Pat. No. 1,324,583, issued in the name of Carlson, describes a wire twisting tool adapted to hold free adjacent wire ends. The Carlson tool provides a particular special relationship to allow for uniform twisting. U.S. Pat. No. 3,092,152, issued in the name of Neff, describes a wire twisting and cutting tool that grips a plurality of wires for twisting in a perpendicular manner. The Neff tool provides a cutting edge to trim the wires once the cable assembly is achieved. U.S. Pat. No. 7,124,786, issued in the name of Gowhari, describes linesman type pliers with a wire splice twister. The jaws provide a tapered recess to allow for wire insertion and a twisted splice when the pliers are manually rotated. 
     Additionally, ornamental designs for a wire twisting tool exist, particularly, U.S. Pat. Nos. D 485,146 and D 494,032. However, none of these designs are similar to the present invention. 
     While these devices fulfill their respective, particular objectives, each of these references suffer from one (1) or more disadvantages. Many of these devices are unfit to manipulate a plurality of wires. Those devices which are suited for manipulating a plurality of wires are not suited for the process of separating such cable assemblies. Furthermore, such devices are designed to grip a plurality of wires in a manner which is not perpendicular to the axis of twisting, thereby limiting the accessibility of use. Accordingly, there exists a need for a wire twisting device without the disadvantages as described above. The development of the present invention substantially departs from the conventional solutions and in doing so fulfills this need. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing references, the inventor recognized the aforementioned inherent problems and observed that there is a need for a wire twisting device that is suitably adapted to manipulate a plurality of wires in a manner which is suitable for the processes of both assembling and separating cable assemblies and in a manner which is best suited for use in a variety of situations, particularly those situations in which access is limited in some manner. Thus, the object of the present invention is to solve the aforementioned disadvantages and provide for this need. 
     To achieve the above objectives, it is an object of the present invention to provide upper and lower jaw members wherein the aforementioned wires and cable assemblies may be inserted and manipulated. The jaws function in the manner of pliers inasmuch as their purpose is to secure a firm grip upon wires and cable assemblies. 
     Another object of the present invention is a plurality of pivoting members coupled to the upper and lower jaws. The pivoting members couple to the jaw members in a way such that the device functions in the manner of pliers, wherein the user may close the jaw members by manually gripping the pivoting members. 
     Yet still another object of the present invention is to provide a locking mechanism that is connected to the upper and lower jaw members. It is the purpose of the locking mechanism to allow the user to maintain the closed position of the upper and lower jaw members, once achieved, without continuous application of manual force. 
     Yet still another object of the present invention is to provide a plurality of channels formed within and between the upper and lower jaws, wherein these channels are linear and adapted to grip the electrical wires. The channels are oriented in a direction which is perpendicular to the pivoting axis. 
     Yet still another object of the present invention is a one-way fixture formed at the lower jaw and oriented perpendicular to the aforementioned channels. This one-way fixture is designed to bend downward when the upper and lower jaws are pressed together, in a manner which allows the wire to be guided freely along the channels. 
     Yet still another object of the present invention is to provide a method of utilizing the device that provides a unique means of assembling and separating a plurality of wires and cable assemblies in a manner which allows the user to do so quickly and easily and in cases in which access is limited in some way. 
     Further objects and advantages of the present invention will become apparent from a consideration of the drawings and ensuing description.
