Smoking Device with Multi-Use Combustion Chamber

Abstract

A smoking device has a cylindrical combustion chamber with a channel along a length, a mouthpiece and a closed cap with a through hole, and an outer shell having an inside diameter and a second length, with a second channel opening through a wall of the outer shell and a third channel in a portion of the outer shell away from the second channel. The outer shell engages the combustion chamber in a slip fit, enabling a user to rotate the outer shell. The first and second channels are aligned such a user may load smokable material into the combustion chamber, and the user is enabled to rotate the outer shell to align the third channel with the first channel, such that material may be ignited through an intersection of the first and the third channels at different positions along the length.

1 . A smoking device, comprising:
 a cylindrical combustion chamber having an axis, an outside diameter and a first length greater than the outside diameter, with a first channel parallel with the axis opening through a wall of the combustion chamber along a portion of the length;   a mouthpiece adapted to engage a first end of the cylindrical combustion chamber, the mouthpiece tapered to an outside end with an opening through the mouthpiece into the combustion chamber;   a closed cap having a longitudinal through hole, the closed cap adapted to engage a second end of the combustion chamber; and   an outer shell having an inside diameter and a second length, with a second channel opening through a wall of the outer shell for a portion of the length parallel with the axis, the second channel having a width equal to the width of the first channel, the outer shell also having a third channel through the outer shell in a portion of the outer shell away from the second channel;   wherein the outer shell engages the outside diameter of the combustion chamber in a slip fit along the length of the combustion chamber between the mouthpiece and cap, thereby positioning the outer shell with the combustion chamber enabling a user to rotate the outer shell on the combustion chamber;   wherein the first and second channels are aligned such that the combustion chamber is open to the outside through the aligned longitudinal channels enabling the user to load smokable material into the combustion chamber; and   wherein the user is enabled to rotate the outer shell to align at least a portion of the third channel with the first channel, such that material may be ignited and smoke may be drawn through an intersection of the first and the third channels at different positions along the length.   
     
     
         2 . The smoking device of  claim 1  wherein the third channel is a continuous channel that follows a spiral path around the axis. 
     
     
         3 . A method for consuming smokable material, comprising:
 machining a first channel opening through a wall of a cylindrical combustion chamber along a portion of a length of the combustion chamber and parallel to an axis of the combustion chamber;   engaging an outer shell having an inside diameter of a dimension to form a slip fit with the outside diameter of the combustion chamber over the combustion chamber, the outer shell having a second channel opening through a wall of the outer shell for a portion of the length parallel with the axis, the second longitudinal channel having a width equal to the width of the first channel of the combustion chamber, the outer shell also having a third channel through the wall of the outer shell in a portion of the outer shell away from the second channel;   engaging a mouthpiece to one end of the combustion chamber, the mouthpiece open from an outside end into the combustion chamber;   engaging a cap to an opposite end of the combustion chamber from the mouthpiece, the cap having a through hole parallel with the axis of the combustion chamber;   rotating the outer shell relative to the combustion chamber such that the first and second channels are aligned;   loading smokable material into the combustion chamber through the aligned first and second channels;   rotating the outer shell relative to the combustion chamber such that a portion of the third channel intersects with a portion of the first channel;   igniting the smoking material through the intersection; and   drawing air by the mouthpiece through the intersection, conducting smoke through the mouthpiece to the user.   
     
     
         4 . The method of  claim 3  wherein the third channel is a continuous channel that follows a spiral path around the axis.
