BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   This invention relates to a Cable Wrench and, more particularly, this invention relates to a Cable Wrench that guides, connects and disconnects an F-Connector male end, attached to a coaxial cable, to an F-Connector female connection on a TV, VCR, computer or any other device that uses coaxial cable or a cable splitter. Further, this invention prevents the coaxial cable from becoming disengaged, or from slipping out of the cable wrench; it also provides a low cost, precise, easily manufactured tool. This tool will be extremely valuable to persons skilled in the field of cable installation and it will also be extremely valuable to lay persons who occasionally have to connect or disconnect coaxial cable. 
   2. Description of Related Arts 
   The function of this invention is carried out today using a tool that has a wrench socket that includes a socket connection portion adapted to receive a lug member and a straight slot portion that runs axially along the length of the handle for coaxial cable placement. With this tool it is necessary to run or place the coaxial cable into the straight slot to place the socket connection portion over the lug member. The tool is then rotated to tighten or loosen the connection. While using the current tool, and during rotation, it is common for the coaxial cable to eject, or to pop out of the straight slot, at which point the cable tends to wrap around the cable tool and the user&#39;s hand and can also cause the cable to break away from the F-Connector. Also, the current tool is not wide enough behind the hex stop, thus preventing the tool from turning freely. In other words, it does not allow or have room for a crimped F-Connector, and therefore the tool is unable to rotate freely around the F-Connector. Also, the current tool is narrow at the leading end of the tool, thereby covering and obscuring the nut and the small copper wire of the coaxial cable, making it difficult for the user to see and to place the wrench end of the tool over the connector ring of the male end of the F-type connector. 
   Another existing tool in the art is a screw-driver based design equipped with a straight slot down the side and a hex head. This tool slides over a coaxial cable and down to an F-Connector. With simple rotation, like a screwdriver, the connector can be tightened or loosened. This tool is intended to simplify the process of attaching and removing coaxial cables by preventing the wrapping of the cable around the tool and the user&#39;s hand. (See U.S. 20020002882, Little Fingers, Lucius Neil Jonett.) Again, however, the problem with this tool is that because it utilizes a straight slot the coaxial cable does not stay in the slot. Consequently, the cable wraps around the user&#39;s hand and is not stable, making it difficult to screw the connector ring. Also, the tool does not allow for easy use with a crimped F-Connector, and therefore it is unable to freely rotate around the F-Connector. 
   Another prior tool is an F-type connector installation and removal tool by Michael Holland, U.S. 20040092165. This is a tool that is operable for connecting a male F-type coaxial cable connector to a female F-type connector. The tool includes a wrench portion and a grasping portion that is affixed to and integral with the wrench portion. The leading end and preferably the trailing end of the grasping portion are slotted. This tool allows accessibility to tight spaces, but again, this is a slotted tool and the slot configuration does not prevent the cable from wrapping around the user&#39;s hand. Also, the current tool does not allow for a crimped F-Connector, and therefore the tool is unable to rotate around the F-Connector freely. 
   Still another prior tool is one by Zamanazadeh, U.S. Pat. No. 5,992,010 that discloses a coaxial cable connecting tool that includes a hollow elongated housing comprised of two halves hinged together. The halves are closed around a female coaxial cable connector. When the halves are closed a hexagonal hole is formed at one end, and another hole is formed at the opposite end. The hexagonal sleeve on the connector is snugly positioned in the hexagonal hole, and the cable is positioned through the opposite hole. The sleeve is then rotated by turning the housing by hand. The housing is substantially wider than the sleeve on the connector, and includes a hexagonal outer surface, so that it may be easily gripped and turned by hand. In a second embodiment the housing is provided as a built-in component on new connectors. Again, this tool does not provide an extra wide notch at the hex end for wide or crimped cable; it does not provide an extra notch or cut away for visibility; nor does it prevent the cable from wrapping around the tool or the user&#39;s hand. 
   The present invention provides several advantages over the currently existing tools. With respect to the currently existing tools, none of them prevent the cable from wrapping around the tool and/or the user&#39;s hand; they do not allow for a wide or crimped F-Connector; and they do not provide an extra wide notch or cut away at the wrench portion to enable better visibility while connecting the male to the female ends.

   DETAILED DESCRIPTION OF THE INVENTION 
   Brief Description of the Invention 
   As the basis for the present invention, the conventional art involves coaxial cable connector tools that have any or all of the following: a straight slot portion for the coaxial cable; a covered or a narrow hex end that prevents visibility of the cable tool connection to the connector ring; a portion behind the hex stop that prevents the rotation of crimped F-Connectors because the portion behind the hex stop is not wide enough to compensate for the flare of a crimped F-Connector, thereby causing damage to the cable connection and to the F-Connector. 
   The present invention uses either a curved slot portion, with or without a sleeve cover, or a straight slot portion with a sleeve cover. The present invention also uses an extra wide notch or cut away at the wrench end to enable visibility. Finally, the present invention utilizes a wider section behind the hex stop, that can run the entire length of the tool, to allow for wide or crimped connectors. Because of the previously mentioned problems in the art the inventor has worked to create the features of the present invention to address these issues and problems. The present invention prevents the coaxial cable from wrapping around the tool and/or the user&#39;s hand; the present invention is wider behind the hex stop so as to enable the tool to turn freely around the F-Connector and to allow for wide or crimped F-Connectors thus avoiding damage to the cable connection; the present invention has an extra wide notch or cut away at the wrench end to enable better visibility while connecting the male to the female ends. 
   The features of the invention believed to be novel are set forth with particularity in the appended claims. However, the invention itself, both as to organization and method of operation, together with further objects and advantages thereof may be best understood by reference to the following description taken in conjunction with the accompanying drawings. 
   EMBODIMENT OF THE INVENTION 
   The present invention provides a tool for connecting or disconnecting coaxial cable, or any other cable that utilizes a hex nut; the tool prevents the coaxial cable from wrapping around the tool and/or the user&#39;s hand; the tool is usable with a crimped F-connector; the tool provides better guidance for the cable, it provides better visibility during operation and avoids cross threading of the F-Connector to the female connectors. An examples of this invention are explained with reference to  FIG. 1  through  FIG. 6 . 
     FIG. 1  is a perspective view of a cable tool  10  shown without a sleeve. The cable tool  10  is of integral construction and comprises a wrench portion  40  at a leading end  60  where the cable tool is a hollow, rigid, substantially cylindrical member and the wrench portion  40  has an inner chamber  160  that has a shaped portion  120  dimensioned to matingly engage a shaped outer surface of a connector  100 . Further, the cable tool  10  has a curved slot  20  or an S-curve slot that runs coextensive with the axial length of the entire body of the cable tool  10 , from a leading end  60  to a trailing end  70 . 
     FIG. 2  is a perspective view of a cable tool  10  shown with the curved slot  20  and a sleeve  30 . The cable tool  10  is of integral construction and comprises a wrench portion  40  at a leading end  60  where the cable tool  10  is a hollow, rigid, substantially cylindrical member and the wrench portion  40  has an inner chamber  160  that has a shaped portion  120  dimensioned to matingly engage a shaped outer surface of a connector  100 . Further, the cable tool  10  has a curved slot  20  that runs coextensive with the axial length of the entire body of the cable tool  10 , from a leading end  60  to a trailing end  70 . Still further, the cable tool  10  has a sleeve  30  that fits matingly and encapsulatingly over the main body of the cable tool  10  and that runs coextensive with the axial length of the body of the cable tool  10 . Also, the sleeve has a curved slot  32  that runs the length of the sleeve  30  and where the curved slot  32  is wide enough to allow a coaxial cable to pass through the slot. 
     FIG. 3  is a perspective view of the cable tool  10  shown with a straight slot  170  and with a sleeve  30 . 
     FIG. 4  is a perspective view of the cable tool  10  and is more particularly an expanded view of the cable tool and the sleeve  30 .  FIG. 4  shows an embodiment where the sleeve  30  could have one or more tang  34  that are used with one of more tang stops  36  that are formed on the cable tool  10 . The tangs and tang stops are used to prevent the sleeve from rotating completely around the tool. When the sleeve is rotated clockwise the tangs strike the tang stops, thereby preventing the sleeve from further rotation and effectively locking the coaxial cable within the chamber. When the sleeve is rotated in the counterclockwise direction the tangs strike the tang stops on the opposite side of the tool, again preventing the sleeve from completely rotating around the tool. When turned in this direction they effectively stop the tool in an open position, enabling insertion and removal of the coaxial cable. 
   In lieu of the tangs and tang stops the cable tool  10  could have one or more ridges that run axially along the length of the body of the sleeve  30  and that matingly engage in at least one slot that run axially along the length of the body of the cable tool  10  that lock the sleeve  30  in either an open or closed position thereby acting as stops to prevent the sleeve  30  from rotating. 
   The operation of the cable tool  10  can be understood by reference to  FIG. 1  and  FIG. 6 . To operate the cable tool  10  a coaxial cable  90  is fed through the curved slot  20  along the axial length of the entire body of the cable tool  10  and into the inner chamber  160 . After the coaxial cable  90  is resting within the inner chamber  160  of the cable tool  10  the coaxial cable  90  is prevented from falling out of the inner chamber  160  due to the curved slot  20 . The cable is secured within the inner chamber  160  and this prevents the coaxial cable  90  from wrapping around the cable tool  10  and/or the user&#39;s hand when the tool is operated. Once the coaxial cable  90  is positioned within the inner chamber  160  of the cable tool  10 , the cable tool  10  is advanced along the length of the cable until the wrench portion  40  engages the male F-type connector  100 . When the cable tool  10  is thus disposed with respect to the male F-type connector  100 , the shaped inner surface  120  of the cable tool  10  engages the shaped outer surface of the connector ring  100 . The male F-type connector is then matingly engaged with a female F-type connector. The grasping portion  80  of the cable tool  10  is then gripped by fingers and the cable ol  10  is rotated clockwise to connect the connectors or counterclockwise to disconnect the connectors. After the connectors are fully connected or disconnected the coaxial cable  90  is removed from the inner chamber  160  by pulling the coaxial cable  90  through and along the curved slot  20  that runs along the axial length of the entire body of the cable tool  10 , thereby freeing the coaxial cable  90 . 
   An alternative embodiment is best understood by reference to  FIG. 3 . To operate the tool of this embodiment a coaxial cable  90  is fed through a straight slot  170  along the axial length of the entire body of the cable tool  10 , through a straight slot along the length of the sleeve, and into the inner chamber  160 . After the coaxial cable  90  is resting within the inner chamber  160  of the cable tool  10  the sleeve  30  is rotated either clockwise or counterclockwise, moving the slotted portion of the sleeve and thus covering the coaxial cable  90 , creating a closed, secure chamber where the coaxial cable  90  rests within. 
   A variation of this embodiment utilizes a sleeve  30  where the sleeve  30  has one or more tang  34  and one or more tang stops  36 . The tangs and tang stops are used to prevent the sleeve from rotating completely around the tool. When the sleeve is rotated clockwise the tangs  34  strike the tang stops  36 , thereby effectively stopping further sleeve rotation and locking the coaxial cable  90  within the chamber, preventing the cable  90  from escaping the inner chamber  160 . When the sleeve is rotated in the counterclockwise direction the tangs strike the tang stops on the opposite side of the tool, again preventing the sleeve from completely rotating around the tool. When turned in this direction they effectively stop the sleeve rotation in an open position, enabling insertion and removal of the coaxial cable. 
   Another variation of this embodiment utilizes a cable tool  10  that could have one or more ridges that run axially along the length of the body of the sleeve  30  and that matingly engage slots that run axially along the length of the body of the cable tool  10  that secure or lock the sleeve  30  in either an open or closed position thereby acting as stops to prevent the sleeve  30  from rotating. 
   Another alternative embodiment of the present invention is best understood by reference to  FIG. 2 . To operate the tool of this embodiment a coaxial cable  90  is fed into the curved slot  20  along the axial length of the entire body of the cable tool  10  and into the inner chamber  160 . After the coaxial cable  90  is resting within the inner chamber  160  of the cable tool  10  a sleeve  30  is rotated clockwise or counterclockwise, thus covering the coaxial cable  90  and creating a closed chamber where the coaxial cable  90  rests within. By rotating the sleeve  30  and creating the closed chamber the coaxial cable  90  is prevented from falling out of the inner chamber  160 . Alternatively, the user could choose to not rotate the sleeve  30 . If the user did not rotate the sleeve  30  the coaxial cable  90  is still prevented from falling out of the inner chamber  160  because of the curved slot  20 . Both configurations prevent the coaxial cable  90  from wrapping around the cable tool  10  and/or the user&#39;s hand. Once the coaxial cable  90  is positioned within the inner chamber  160  of the cable tool  10  and the sleeve  30  is either rotated to create the closed chamber or left open the cable tool  10  is advanced along the length of the cable until the wrench portion  40  engages the male F-type connector  100 . When the cable tool  10  is thus disposed with respect to the male F-type connector  100 , the shaped inner surface  120  of the cable tool  10  engages the shaped outer surface of the connector ring  150 . The male F-type connector is then matingly engaged with a female F-type connector. The grasping portion  80  is then gripped by fingers and the cable tool  10  is rotated clockwise to connect the connectors or counterclockwise to disconnect the connectors. After the connectors are fully connected or disconnected the coaxial cable  90  is removed from the inner chamber  160  by rotating the sleeve  30  in the clockwise or counterclockwise direction and by pulling the coaxial cable  90  from the inner chamber  160 , or alternatively, if the user has not rotated the sleeve  30 , by simply pulling the cable out of the inner chamber  160  through the curved slot  20 . 
   This embodiment could utilize a sleeve that could have one or more ridges that run axially along the length of the body of the sleeve  30  and that matingly engage slots that run axially along the length of the body of the cable tool  10  that lock the sleeve in either an open or closed position thereby acting as stops to prevent the sleeve  30  from rotating. 
   This embodiment could also utilize the tangs and tang stops as described above to prevent the sleeve from continual rotation around the cable tool body. 
   Also, the outer surface or grasping portion  80  of the cable tool  10  of any of the embodiments may be knurled or textured, it may be ribbed, have ridges, or any other raised portion, or it may have any other alteration or modification of the exterior surface that is designed to assist the user and to prevent finger slippage when torque is applied to the tool  10 . 
   Another variation of the any of the previously described embodiments of the cable tool  10  is an extra wide notch or cut away  50  at the leading end  60  that allows the operator to easily and more fully see the connection process. This embodiment of cable tool  10  still allows the user an adequate shaped portion  120  that sufficiently grabs the connector ring while simultaneously allowing the user to view the connection to facilitate ease of operation. 
   A final variation of the cable tool  10  further provides a wider portion inside the tool, behind the hex stop, directly adjacent to and behind the wrench portion. This wider portion allows a crimped or a large cable end to fit without catching on the wrench portion during tool operation and enables the tool to turn freely about the F-Connector  100  thereby avoiding damage to the cable connection or to the F-Connector. This extra wide portion may be only directly behind the hex stop or it may run the entire length of the tool. Many F-Connectors have a flared portion between the end of the F-Connector adjacent to the coaxial cable and the coaxial cable and, due to this flare, it is often difficult to rotate the F-Connector. The present embodiment eliminates this problem. 
   It is readily apparent that the above-described invention has the advantages of wide commercial utility. It may be understood that the specific form of the invention hereinabove described is intended to be representative only, and certain modifications within the scope of those teachings will be apparent to those skilled in the art without departing from the spirit and scope of the invention. 
   While the foregoing invention has been shown and described with reference to preferred embodiments, it will be understood by those possessing skill in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Accordingly, reference should be made to the following claims in determining the full scope of the invention.
