Abstract
A smoking device is disclosed whereby smoke and other gases of combustion can be diluted with air to a pre-selected mixture before being inhaled by a smoker. This is achieved by the use of a carbureting tube which can introduce a metered amount of air into a smoke chamber and thereby dilute the smoke to any desired concentration. The smoke is drawn into the smoke dilution chamber by a piston moving towards the outlet end of the chamber, and then pumped out of the smoke dilution chamber by reversing the motion of the piston. A water chamber may also be included to permit the smoke and other gases to be cooled prior to entering the smoke dilution chamber.
Claims13
A smoking device comprising:
- (a) a cylindrical housing having an outlet end and an inlet end,
- (b) a reciprocating pump-like plunger carried within said cylindrical housing and thereby to provide a smoke dilution chamber near said cylindrical housing's inlet end and an air chamber near said cylindrical housing's outlet end,
- (c) a combustion bowl having a burning chamber fixed to said cylindrical housing,
- (d) a passageway connecting said combustion bowl to said inlet end,
- (e) an on-off valve means operatively positioned between said burning chamber and said inlet end to permit smoke to pass from said burning chamber to said smoke dilution chamber when said valve is in an open position,
- (f) a cap means having at least one vent hole and a central opening for covering said outlet end of said cylindrical housing and
- (g) a slidable hollow carbureting tube extending through said central opening and into said smoke dilution chamber said carbureting tube having an inlet section and an outlet section, said inlet section having said pump-like plunger fixed thereto and said outlet section being extended beyond said cylindrical housing to permit pre-determined amounts of ambient air to be drawn into said smoke dilution chamber as said plunger is moved toward said outlet end of said cylindrical housing by regulating the degree to blockage imposed on said outlet section of said hollow carbureting tube.
The smoking device of claim 10 wherein said on-off valve means is activated by slidably extending said cylindrical housing.
