         the cord and both ends are exposed throughout the winding
         process, making it unnecessary for the cord to be completely
         unwound in order to access the plug end.
           Figure 16 depicts a side view of the wire spool 200. The
         wire spool 200 has a rotating handle 150 that is connected
         to a hollow internal shaft 250 that allows for cord 240 to be
         wound on and off the internal shaft 250. The cord 240 has
         two connection points that are located on the top 220 and
         on the bottom 225. The method of spooling and unspooling
         involves rotating the spool in the clockwise and/or counter-

                                                              The cord reel works best when the side outlet is centered on
                                                              the housing. Based on the length of the cord the dimensions

                                                               Now referring to figure 18, which shows an exploded view of

         Figure 16: Side cross section view of the cord storage reel apparatus.  Now referring to figure 19, which shows a top view of a

         posed on either side of the reel while the other end is wound   three interconnecting gears 520 which are connected to the
         or unwound. It also allows the user to plug into items inside   inner/output gear 530. Use of the cord reel system involves
         or outside of the bucket while the reel is on top of it. The reel
         does not have to be opened in order to load the cord and both
         ends are exposed throughout the winding process, making it
         unnecessary for the cord to be completely unwound in order
         to access the plug end.
           Figure 17 shows the measurements of the different constit-
         uents of the cord reel apparatus 300. Several experiments
         and trials performed have yielded these ideal size/measure-
         ments and position for all the constituents for optimizing the
         ease and pace of operation of winding and unwinding exten-
         sion cords. For the housing the outer diameter is represent-
         ed by 310 is no greater than 11 inches, and the outermost
         diameter including the lip protrusion is represented by 320
         is 12 inches and height of the housing is represented by 340
         is 4.75 inches are found to be the ideal measurements. For   Figure 19: Gear mechanism for winding the cord.

                                                              causes the turning of the inner/output gear 530. The inner

                                                              can be used to achieve higher operational efficiency.
