         Cable puller for portable mast
         Pat. 9,850,980 U.S. Class F16G 11/12 Int. Class F16G 11/12
         Inventor: Jeffery Kester, Marshall, TX.
         Assignee: Jeffery Kester, Marshall, TX.
           This patent presents a system and method for pulling a
         cable. The system includes a cable which has at least one
         button located along its length. A cable puller is coupled to
         the cable and has at least one slot for receiving the cable.
         The cable puller also has a plate for engaging the button.
         The cable puller has a sleeve with an upstream end and a
         downstream end, and the plate is located on the upstream
         end. The plate prevents movement of the button upstream
         of the plate.

         ment. As depicted, the cable puller 100 is coupled to a cable
         101. As used herein, the term cable shall refer to any rope,   available. This allows tension to be applied along the length

         nent or temporary structures, which couple and secure the
         cable 101 to the ground. In other embodiments the guy wire
         is anchored to a portable rig base beam or matting board.
           As can be seen, the cable 101 has at least one button 106.
         In one embodiment the button 106 is positioned at the end
         of the cable 101, but in one embodiment the cable 101 com-
         prises at least one button 106 positioned along its length.
         Put differently, in one embodiment the cable 101 comprises
         a button 106 which is not located at its ends. The button
         106 can comprise any item which is crimped or otherwise
         secured and coupled to the cable 101. In one embodiment
         the button 106 comprises a National Swage Button manu-
         factured by the Crosby Group. In one embodiment the but-
         tons are swaged or crimped onto the wire permanently.
           The buttons 106, when positioned along the length of the
         cable 101 as opposed to the ends, provides a gripping surface
         along the length of the cable 101 which was previously un-
