     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to cases, caddies and tool boxes. More particularly, the present invention relates to an improved electrician&#39;s wire caddy and tool box apparatus that affords an electrician who is running wire in an installation the ability to pay out wire of one or more different gauges from a plurality of spools that are mounted at the upper portion of a tool box or case, and having a lower storage area with a plurality of compartments for containing articles to be used by the electrician such as tools, receptacles, switches, wire nuts, switch covers and the like. 
     2. General Background of the Invention 
     Electrical installation in buildings occurs in basically two segments. First, the conduit and switch and receptacle boxes are roughed in, locating the routes where the electrical wiring is actually run. At the time the conduit is put in, various boxes for receptacles, switches and the like are located, attached to the conduit and made ready for the mounting of the receptacles and switches. 
     After the conduit is run, and usually before the wallboard is placed on the studs, an electrician returns to pull wire through the conduit and install the various receptacles, switches and other like fittings. 
     The standard wire pulled in circuits of this type is typically No. 12 or gauge 12, typically available on 500 ft. spools. It is not uncommon to pull multiple circuits (i.e. more than one wire) at a single pull. During such a pull, the wire spools should be easily accessible to the electrician, enabling the electrician to pull the wires through the conduit to install the various circuits. 
     Various patents have issued for tool boxes, receptacles, caddies and the like that in some cases support or hold spools. One such patent is U.S. Pat. No. 2,342,954 issued to Mercer and entitled “Spool Holder”. In the Mercer patent, a spool holder includes a base, a pair of spaced, upwardly extending parallel walls carried by the base, a pair of transversely arranged spaced parallel walls angularly disposed with respect to and joined to the outer side of each of the first pair of walls. Each pair of the parallel walls is adapted to rotatably receive at least one spindle for supporting a spool of yarn or the like and a carrying handle mounted upon and extending between the first mentioned pair of walls. The handle is equipped with guide means for receiving the yarn from the spools. 
     A gift wrapping storage container is disclosed in the Homan U.S. Pat. No. 4,186,833. The apparatus provides a hinged cover container having ribbon spool storage and dispensing dowels in the cover and a divided major container portion for storage of folded paper in one section and cards and ribbon in a smaller section. The inside of the cover is provided with loops of elastic ribbon for securing hardware useful for wrapping. 
     The Cohn U.S. Pat. No. 3,150,769 discloses a wire packaging and handling device for items wound on reels such as wire, and specifically to a packaging and handling device for a reel of wire such that individual lengths of wire may be easily unwound without removing the reel from the device. Steaming crates are known for supporting spools of material such as the Carpenter U.S. Pat. No. 1,752,884, and the Daugert et al. U.S. Pat. No. 1,677,385. 
     Patents have also issued for sewing cabinets that have rods for supporting spools of material. Examples of such sewing cabinets include, for example, U.S. Pat. Nos. 1,858,105 and 2,541,845. 
     BRIEF SUMMARY OF THE INVENTION 
     The present invention provides a tool box for an electrician, cable installer or lineman providing both mounting means for the wire-containing spools for paying out wire and storage space for the usual tools, parts and accessories used by the individual installer in the course of installing, routing, or hanging wire or cable. 
     The present invention provides an apparatus that includes side portions, which either by themselves or with additional supports provide a mounting on a shaft or axle for the spools of wire or cable to be installed. Surplus scrap pieces of conduit are normally available on a job site to be utilized as the shaft or axle for supporting the spools. In the course of running the wire or cable, the spool of wire or cable may rotate on the shaft, while being maintained in the central location of the parts and accessories. 
     The enclosed portion of the apparatus provides a storage area that may be fitted with a variety of compartments or receptacles for storage of selected parts and accessories. In differing embodiments of the invention, the dividers for forming the individual compartments may be fixed or moveable, in order to provide different styles of toolboxes meeting the preferences of different electricians. In a preferred embodiment, the apparatus provides a closeable cover that can be hinged or otherwise fashioned to the body of the box to prevent inadvertent loss or removal of parts or accessories when the apparatus is unattended, or during transport.

     DETAILED DESCRIPTION OF THE INVENTION 
     FIGS. 1-9 show generally the preferred embodiments of the apparatus of the present invention designated generally by the numeral  10  in FIG.  6 . Electrician&#39;s wire caddy  10  supports a plurality of spools  26 - 29 , each with a length of wire W that can be payed out for wiring a building or like structure. Caddy  10  also contains tools and articles  41 - 48  that an electrician uses and can access without requiring repositioning or removal of the spools  26 - 29 . 
     Case  10  can be constructed of any structural material such as plastic, wood, aluminum or the like. 
     A supportive base panel  11  or bottom connects with front wall  16 , rear wall  17  and side walls  12 ,  13 . Each side wall  12 ,  13  has a handle  14 ,  15  respectively. End wall  12  has one or more upper flat surfaces  18 . End wall  13  has one or more upper flat surfaces  19 . The upper flat surfaces  18  can include surfaces  18 A,  18 B or  19 A,  19 B as shown in FIG.  4 . In an alternate construction as seen in FIG. 7, all of the upper flat surfaces  18  can be at the same elevational position, such as the plurality of surfaces  18 C shown in FIG.  7 . 
     Each upper flat surface  18 ,  19  has a one or more semicircular shaped recesses  20 ,  21  respectively. Recesses  20 ,  21  are shaped to receive end portions of spool support rods  30  as shown in FIGS. 3-4. In various preferred embodiments, recesses  20 ,  21  are of a diameter and depth to receive standard diameter conduit (e.g., ¾ inch, 1 inch diameter) which, when cut to suitable length, serves as the shaft or support rods  30 . Each recess  20 ,  21  is shaped to closely conform to an end of a rod  30  so that rods  30  are securely held when a user pulls electrical wire W from a spool  26 , 27 , 28 , 29  as indicated schematically by arrows  40  in FIG.  6 . In preferred embodiments, recesses  20 ,  21  are of a diameter and depth to receive rods  30  which are lengths of scrap electrical conduit which is available on a job. 
     Each spool  26 ,  27 ,  28 ,  29  can carry multiple and different gauge wire for example. Each spool  26 ,  27 ,  28 ,  29  is supported in an elevated position above the receptacles  31 - 35  of storage area  25 , enabling a user to access them notwithstanding the above supported spools  26 - 29 . 
     In FIGS. 2-4 and  6 , some of the recesses  20 ,  21  are placed at higher elevational positions. This construction as shown in FIGS. 3 and 6, enables some of the rods  30  to be placed at higher elevational positions so that spools on an upper most rod  30 A (such as spool  26  in FIG. 6) can pay out such as larger gauge wire W (e.g., Romex® cable available from General Wire and Cable, Inc.) above spools such as  28  and  29  that are on a lower rod  30 B. In alternative embodiments, upper most rod may be a larger diameter, as 1″ conduit so as to support a larger, heavier spool  26  of wire thereby providing the electrician the opportunity to run different types of wire out of the case  10 . It is usual that heavy duty insulated cable such as Romex® cable available from General Wire and Cable Company may need to be run during the time that such as 12 and 14 gauge wire. By providing the higher elevational recesses  20 , 21  on surfaces  18 B,  19 B, the heavy duty cable may be supported above and clear of receptacles  31 - 35 . In FIG. 7, the recesses  20  are at the same elevational position, in which embodiment may be adapted for installation of lighter gauge wire. This would be true for both of the end walls  12  and  13  though only wall  12  is shown in FIG. 7 for clarification purposes. This latter embodiment of the invention for applications when lighter gauge wires, particularly signal, communication or instrument wiring is being routed in a building under construction. 
     Storage area  25  is defined by a plurality of baffles including central baffle  36 , rear baffle  37 , and front baffles  38 , 39 . Baffles  36 - 39  may be immovably fixed to each other and on base  11 , or in alternative embodiments may be moveably fixed in case  10  whereby the sides of the receptacles  31 - 35  may be adjusted in size to better accommodate various tools or electrical parts being utilized in an installation. In the embodiment illustrated in FIGS. 8 and 9, a cover  22  forms a closure to each receptacle  31 - 35 . Cover  22  attaches to rear wall  17  with such as hinges  23 . Clasp  24  secures cover  22  in a closed position by fastening cover  22  to front wall  16 . Alternatively, cover  22  may be removably attached to case by such as clasps  24  being disposed in pairs on opposite sides and ends of walls  16 ,  17 . 
     In FIG. 3, reference line  49  designates a plane that is defined by the top surface  50  of cover  22 . A distance D is shown defining the distance between the bottom of a rod  30 A or  30 B and the plane  49  defined by the upper surface  50  of cover  22 . This distance is sufficient to enable a user&#39;s hand to access the various compartments  31 - 35  that contain the various tools and articles  41 - 48  contained therein. In the preferred embodiment, this distance D is preferably between about 4 and 6 inches. In the preferred embodiment, the spools  26 - 29  preferably provide a maximum diameter of about 7 inches, except when such as heavy duty cable is mounted on a spool (e.g.,  26 ). In this latter instance, the spool  26  may be 9 to 10 inches in diameter and need to be mounted so as to clear not only recesses  31 - 35  but also those spools suspended below on surfaces  18 A,  19 A. For a case  10  to accommodate this usage, surfaces  18 B,  19 B are required to be about 15 to 18 inches above base  12 . 
     In FIG. 5, exemplary tools and articles are shown being contained within the various compartments  31 - 35 . These include pliers  41 , crimping tool  42 , screwdriver  43 , electrician&#39;s tape  44 , fasteners box  45 , switch cover  46 , receptacle cover  47  and a plurality of wire nuts  48  of differing sizes.
