     BACKGROUND OF THE INVENTION 
       [0002]    1. Technical Field 
         [0003]    The present invention relates to a twister apparatus and method for providing wire twisting. In one aspect, the present invention relates to a wire twister apparatus and method for providing a wire twisting prior to applying an insulator end cap to joined twisted wire strands. In one aspect, the present invention relates to apparatus and method for making wiring connections and to making electrical connections between bare ends of wires or conductors. In one aspect, the present invention relates to a wire twister apparatus and method for joining bare end portions of a plurality of insulated electrical wires to receive a wire connector or wire nut on the joined outer end portions of the joined wires. 
         [0004]    2. Background 
         [0005]    When working with residential or commercial buildings, electrical wiring is necessary to supply electricity to various products that require electrical current to function properly. Most electrical wiring applications use #14, #12, or #10 solid copper wire. It oftentimes is necessary to join 2, 3, 4, 5, or 6 wires together to complete the circuit. The problem in the past was that with the tools that electricians used, the wire twist was not tight enough and did not provide a sufficient number of twists to make a good connection. 
       INTRODUCTION TO THE INVENTION 
       [0006]    An electrical power distribution system is required in residential and commercial buildings to transmit electricity safely and efficiently from the point of entry, e.g., such as, the breaker box, to various points for use in lighting, heating, and appliances. Circuits may be required to split numerous times before reaching final termination. Circuit splitting may require 2, 3, 4, 5, or 6 conductors to be connected as tightly as possible and with as much contact as possible to reduce heating and any potential for fire while completing the circuit. Currently, electricians use side cutting pliers to twist the conductors, resulting in connections that often become loosened later, even after being placed in wire nuts, causing heating or circuit failure. 
         [0007]    Products or services currently available on the commercial market to solve the problem are lacking. Most manufactures sell “electrician&#39;s side-cutting pliers.” The electrician&#39;s side-cutting pliers are slow and require many steps to twist and then release your grip on the pliers to secure a new position on partially twisted wires, over and over again. 
         [0008]    Currently available products or services are inadequate because they do not provide enough attention to this problem. Side cutting pliers do not do a consistent or adequate job of twisting the conductors tightly enough. An electrician must make multiple grips and wrist turns with the pliers to complete the job. While the necessary wire strippers and wire nut connectors are available, tools to twist and join connectors properly are not available. 
         [0009]    Apparatus and method are needed to provide an electrician a novel tool having no moving parts to supply the inadequacies of the prior art in a one hand operation in cramped and physically awkward body positions often required in construction. 
         [0010]    Other devices are available but are too complicated or bulky to have gained acceptance by the electrical trade. Other devices include those referenced in U.S. Pat. Nos. 4,074,732, 4,865,086, 5,379,809, and 5,887,631. 
         [0011]    U.S. Pat. No. 4,074,732 discloses a unitary multi-purpose tool which cuts, strips, and twists together wires in preparation for the installation of insulating cap-type twist-on wire connectors. 
         [0012]    U.S. Pat. No. 4,865,086 discloses twisting the conductors of one or more electrical wires by assembling the conductors into a bundle; inserting the bundle of conductors into a wire twister elongate body having an axially extending open cavity at one end and having a closed cross-section with four sides, at least one of the sides of the cavity being inclined to the axis of the body so that the cavity is tapered inwardly away from the open end, the ratio of the length of the longest side to the length of the shortest side at the axial position at which the conductors, when twisted to form a substantially circular array, contact two opposite sides of the cavity being from about 1.0 to about 3.0; and imparting rotation to the wire twister relative to the conductors, while maintaining the conductors in contact with at least two of the sides of the cavity. 
         [0013]    U.S. Pat. No. 5,379,809 discloses a wire twisting device to join bare end portions of insulated electrical wires together in a radially and longitudinally uniform spiral. The joined wires receive a hollow wire connector or nut on the outer end portions. The wire twisting device has an insulated handle and wire twister having a central cavity having protrusions extending inwardly toward the center to form wire receiving channels between adjacent protrusions such that the bare end portions to be joined are placed in a corresponding channel. As the wire twisting device is rotated relative to the electrical wires, it moves longitudinally relative to the insulated electrical wires to twist the bare end portions together to form the uniform spiral configuration prior to application of the hollow wire connector or nut. 
         [0014]    U.S. Pat. No. 5,887,631 discloses a wire twisting and capping apparatus having a main body and a drive element connected to a first end along the longitudinal axis. Conductor-reception channels are arranged parallel to the longitudinal axis at a second end. A translatable sleeve assembly supported by the main body portion includes a locking assembly at a first end and a main sleeve portion attached to the locking assembly with insulator end cap receivers located at a second end of the translatable sleeve assembly for engaging an insulator end cap when the translatable sleeve assembly is translated away from the drive element. The wire twisting and capping apparatus twists bare ends of conductors into an intertwined unitary conductor end structure and installs an insulator end cap onto the intertwined unitary conductor end structure. 
         [0015]    While prior wire twister mechanisms having moving parts are useful for an intended purpose, an apparatus and method are needed to provide service in awkward body positions and close working spaces. 
         [0016]    There exists a need for a wire twister apparatus and method which provide ease of operation and consistent, tightly twisted wire bundles in making electrically sound connections. 
         [0017]    There exists a need for a wire twister apparatus and method which further provide reliable and electrically sound connections for both professional and novice users. 
         [0018]    It is an object of the present invention to provide means and method to join 10 gauge, 12 gauge, and 14 gauge wire into uniformly twisted, tight connections which are ready to be secured and insulated with a wire cap or nut. 
         [0019]    It is an object of the present invention to provide a novel wire twister having no moving parts which can be utilized by electrical craftsmen to make consistent, reliable wire connections. 
         [0020]    It is an object of the present invention to provide a novel wire twister which also can be utilized by unskilled craftsmen to make consistent, reliable wire connections. 
         [0021]    It is another object of the present invention to provide a wire twister having a unique shape, at an economical price all the while being unobtrusive. 
         [0022]    It is another object of the present invention to provide a wire twister which can be held and operated in one hand, while still providing the same tightly twisted wire grouping of from 2 to 6 wire conductors. 
         [0023]    It is still another object of the present invention to provide a wire twister having the operating life of a common hand screw driver. 
         [0024]    It is another object of the present invention to provide a wire twister with easily loaded sockets, pockets, or chambers to facilitate a quick, smooth operation. 
         [0025]    It is another object of the present invention to provide a wire twister which is less expensive than conventional wire twisters. 
         [0026]    It is still another object of the present invention to provide a wire twister easily carried on the person and which can be utilized in close working spaces. 
         [0027]    These and other objects of the present invention are provided by the apparatus and method as disclosed and described in the detailed description of this specification and the claims which follow. 
       SUMMARY OF THE INVENTION

         [0090]    Referring now to  FIG. 30 , the 6-wire twisting cylinder  64  of the detachable socket wire twisting apparatus  40  of the present invention as shown in  FIG. 29  further is shown with the handle connecting shaft socket  54  and ball receiving socket  58 . 
         [0091]    Referring now to  FIG. 31 , the 6-wire twisting cylinder  64  of the detachable socket wire twisting apparatus  40  of the present invention as shown in  FIG. 29  further is shown with the circle describing center line  38 , diameter  24 , and counter sink dimension  26  of the 6 wire receiving sockets  16 . 
         [0092]    It has been found that the apparatus and method of the present invention address the problem and provide a simple solution to the requirement of twisting multiple electrical conductors into a tight, electrically sound coil before installation of a wire nut. Devices that could do the job, such as those referenced in the prior patents have been found not to operate in a one-hand operation in cramped and physically awkward body positions often required in construction. 
         [0093]    The wire twister of the present invention provides a hand-powered tool including either a one-piece rigid handle  4 , shaft  8 , and solid cylinder  12 ; or a one-piece rigid handle  4 , and shaft  46 , with a detachable cylinder  52 . A cylinder head  12  or  52  at the end of the shaft  8  or  46  has a circular arrangement of holes evenly spaced on a minor circumference within the circumference of the cylinder  12  or  52 . The holes are drilled into the flat end of the cylinder  12  or  52  ( FIGS. 6 ,  9 ,  12 ,  15 ,  22 ,  25 ,  28 , and  31 ) along the long axis of the cylinder. There are 2, 3, 4 or 6 holes, with the hole diameter in any one tool being sized at 10, 12, 14, or 16 wire gauge. 
         [0094]    The apparatus and method of the present invention provide a tool, which operates with the ease of a hand powered screwdriver or nut driver without a flat keystone tip (flat) or Phillips head. When wires are cut with side cutting pliers, a chisel point results. The apparatus and method of the present invention provides a solid cylinder head  12  or  52  of a hardness sufficient to resist gouging by sharp wire ends; for metal cylinders, a hardness is required to produce a Rockwell B of 40 to 60 as determined by ASTM E 18-07 testing and for plastic cylinders, a hardness of Rockwell R118 or M70 as determined by ASTM D785 testing. The apparatus and method of the present invention provide a cylindrical head  12  or  52  having 2, 3, 4 or 6 holes  16  drilled into the solid cylindrical head  12  or  52 . The drilled holes  16  allow for each wire that is to be twisted, to be inserted into one and one-half inches (1½″) deep holes  16 . With a twist of the tool, all wires twist together. The apparatus and method of the present invention provide an insulated handle  4  of sufficient size to have adequate torque applied from the hand to operate the tool. 
         [0095]    The operator strips all wires of insulation to the required length that need to be connected to each other and then inserts each wire into an individual hole  16  in the cylinder. The wires are held, in one aspect, by their position in a box or current using device, or by hand, to prevent rotation of the bundle. The operator then rotates the tool by hand, causing the wires to twist into a tightly spiraled coil. 
         [0096]    Advantages and benefits of the present invention include a relatively short time to operate the tool to connect the conductors. 
         [0097]    When twisted, the wires will not unwind or fall apart. 
         [0098]    The apparatus of the present invention is a lightweight tool with long operating life. 
         [0099]    Benefits of the wire-twisting tool of the present invention further include an ability to be mass-produced at a low cost compared to devices referenced in prior patents. 
         [0100]    The wire twister tool of the present invention is produced to fit a variety of gauges of wire. 
         [0101]    The speed to rotate the tool is set to the operator&#39;s ability, with the wires remaining in the fixed holes  16 . With side cutting pliers, when the grip is relaxed to take another turn, the conductors often drop, and the process must be restarted. The tool can be easily held and operated with one hand because of its lightweight. 
         [0102]    It has been found empirically that the novel tool of the present invention forms a very tight coil, which does not unwind and which lends itself to the easy application of a wire nut. The tight coil solves the problem of conductor heating and accidental circuit disconnection. 
         [0103]    The tool can be mass produced at a much lower cost than pliers or compound stripping twisting tool. 
         [0104]    The tool is easily stored and carried in a tool pouch for easy portability and availability, which is critically important for an electrician who may have to work from the top of a ladder, wall, or in confined crawl space. 
         [0105]    The tool is produced to fit several wire gauges if required, e.g., such as 16 to 10 gauge. 
         [0106]    It has been found empirically during the development of the wire twister of the present invention that changing the holes from one size to ones that have a slight cone  26  at the very end provides for an ease of entry for the wires. It has been found empirically during the development of the wire twister of the present invention that the number of wires to be accommodated by the tool should be not more than six (6) because more than 6 taxes the ability of the conductors to stay together. 
         [0107]    The apparatus and method of the present invention provide a wire twister that works with one hand. 
         [0108]    The novel wire twister of the present invention allows for easy portability while providing consistent, reliable electrical connections. 
         [0109]    The novel wire twister of the present invention also can be utilized by either professional or novice users. In this manner, the novel wire twister fills a need for a simple, reliable, and consistent tool for joining electrical connections. 
         [0110]    The novel wire twister of the present invention provides a compact, rigid shaped tool, at an economical price that can be easily carried on the person. 
         [0111]    The features of the novel wire twister of the present invention provide operational advantages because it can be held in one hand while providing reliable, consistent, electrically sound connections. A compact shape allows it to be utilized in any spatial orientation while allowing electrical conductors to be easily inserted for twisting. 
         [0112]    It has been found that cost is less expensive than other available conventional devices to perform the same function. 
         [0113]    In one aspect, the instant invention relates to a wire twister device and method to easily and reliably make tight, electrically sound wire connections prior to being completed with the application of a wire nut. 
         [0114]    The novel wire twister apparatus and method provide a tool which can be easily used in standard and awkward positions of work.
