       FIGS. 14   b - 14   c  show a transparent view of the internals of the ash bin  8 . There is a screen  84  for holding charcoal situated within the internal cavity of the ash bin  8 . In another embodiment, the tube-shaped ash bin  8  has a moveable flap  83  at or near the bottom of the ash bin  8  which when in the closed position seals the bottom and when in the open position allows air to flow through the bottom. The flap  83  is actuated by the movable handle  81 . The handle  81  is oriented parallel to the flap  83  so it visually gives an indication as to whether the flap is open or closed. The fixed screen  84  is situated just above the flap  83  in its closed position. The screen  84  separates the interior of the tube into two chambers: the above chamber for charcoal and the below chamber for combustible starting material (newspaper). At the bottom of the bin  8 , there is at least one opening  85  in one of the side walls leading into the newspaper chamber; the aperture or opening  85  is used to allow the newspaper to be lit easily and to encourage air flow. 
     The fixed handle  6  is situated above the movable handle  81  and is designed to aid in handling the ash bin/chimney  8 . In particular, when the charcoal is hot, both handles should be used. The movable handle  81  has a stop to prevent its movement past the horizontal orientation. To prevent inadvertent opening of the flap  83 , the rod  86  on which the flap  83  pivots extends out the back of the bin  8  and is bent to form a leg  82 . While the flap  83  is in its closed position, the leg  82  of the rod  86  is vertical allowing the bin  8  to fit in through the opening in the column  3   a . While the flap  83  is in its open position, the leg  82  extends horizontally preventing the bin  8  from being replaced into the column  3   a . Likewise, while the bin  8  is in the column  3   a , the leg  82  prevents the handle  81  from moving so that the flap  83  will not open. 
     In one embodiment, the procedure for starting the charcoal and using the dual functioning ash bin is as follows: 1) the ash bin  8  is removed from the column  3   a  and if there are any ashes or ash residues, the ash bin  8  is emptied out; 2) the handle  81  is rotated down thereby moving the flap  83  away from the screen  84  and opening the bottom of the ash bin  8  to form a charcoal starting chimney—the flap  83  is moved downwardly by moving the handle  81  in a downward motion to a generally parallel position relative to the ash bin handle  6  and away from one of the connectors  80 ; 3) crumpled-up newspapers are placed in the bottom of the ash bin/chimney  8  and the bin  8  may be placed on the charcoal grate in the firebowl  2  or the grill  9 ; 4) a specified amount of charcoal briquettes are placed into the open topside of the bin  8  and the charcoal sits atop the screen  84 ; 5) the newspaper is lit  9  (access coming from aperture  85 ) and the briquettes are allowed to burn until they have some gray ash on them; 7) the lit charcoal is then poured onto the charcoal grate of the firebowl  2  using the handle  81  and handle  6 ; 8) the flap  83  of the ash bin  8  is then placed in a position adjacent to the screen  84  and the chimney is thereby closed—the flap  83  is moved upwardly by moving the handle  81  in an upward motion to a generally perpendicular position relative to the ash bin handle  6  and connected to both of the connectors  80 ; and 9) the bin  8  is replaced into the column  3   a.    
     Numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the attendant claims attached hereto, this invention may be practiced otherwise than as specifically disclosed herein.
