Smoking pipe accessory for automobile gearshift lever Patent number: 4204551 Issue date: May 27, 1980

“A smoking-pipe, usable as a replacement for a normal gearshift knob in an automobile includes a main body having a cavity, inside which a removable ventilated cartridge used to contain tobacco or other smokeable material fits slidingly. A flexible smoke-tube conducts smoke from the base of the cavity to the user’s mouth, and a magnetically retained cover conceals the cavity, creating the outward appearance of a custom-made shift control knob. An O-ring and a gasket hold the cartridge in the cavity, prevent noise producing vibration of the cartridge against the walls of the cavity, and provide an air seal around the cartridge to enhance air circulation through the smoking matter.”

It is another object of the invention to provide a smoking-pipe which is disguised as a gearshift control knob.

It is a feature of the smoking-pipe of the invention that it safely contains smoking matter to prevent spillage.
