Smoking devices

Claim 2

A smoking device which comprises: a combustion chamber capable of holding a combustible material; a mouthpiece; an air intake conduit connected to said mouthpiece, said conduit having an area contiguous to said combustion chamber but separated from it by a heat-conductive wall shaped and dimensioned to be capable of preventing smoke generated in said combustion chamber from entering said conduit and said mouthpiece; at least one aperture in said wall shaped and positioned to be capable of allowing passage of smoke between the combustion chamber and said conduit; means for opening and closing said aperture, such that when said aperture is open, smoke passes between the combustion chamber and the conduit; when said aperture is in an intermediate position, a mixture of smoke and air from said conduit passes to said mouthpiece; and when said aperture is closed, smoke is prevented from passing between the combustion chamber and the conduit; and volatile substances held within said area.

Claim 3

The smoking device of claim 1 wherein said volatile substances comprise nicotine.

Claim 4

The smoking device of claim 2 wherein said volatile substances further comprise aromatics.

Claim 5

The smoking device of claim 1 wherein said area comprises first elements in close proximity with said combustion chamber, said first elements carrying the least volatile of said substances, and second elements more distal from said combustion chamber, said second elements carrying the most volatile of said substances.

Claim 6

A smoking device which comprises: a combustion chamber capable of holding a combustible material; a mouthpiece having means to form a first air passage communicating directly with exterior air; said combustion chamber and said mouthpiece having means to form a second air passage between them; an air-intake conduit connected to said mouthpiece, said conduit having an area contiguous to said combustion chamber but separated from it by a heat-conductive wall; volatile substances held within said area; said mouthpiece and said air-intake conduit having means to form a third air passage between them; and means for selectively opening and closing said air passages, whereby said first air passage may be opened and said second and third air passages may be closed to admit only pure air to said mouthpiece, or said second air passage is open and said first and third air passages are closed to admit only smoke from said combustible material to said mouthpiece, or said third air passage is open and said first and second air passages are closed to admit only air carrying volatile substances to said mouthpiece, or said second and third air passages are each partially open and said first air passage is closed to admit a mixture of smoke and air carrying volatile substances to said mouthpiece.

Claim 7

A smoking device which comprises: a combustion chamber capable of holding a combustible material; a mouthpiece having means to form a first air passage communicating directly with exterior air; said combustion chamber and said mouthpiece having means to form a second air passage between them; an air-intake conduit connected to said mouthpiece, said conduit having an area contiguous to said combustion chamber but separated from it by a heat-conductive wall; volatile substances held within said area; said mouthpiece and said air-intake conduit having means to form a third air passage between them; and means for selectively opening and closing said air passages, whereby said first air passage may be opened and said second and third air passages may be closed to admit only pure air to said mouthpiece, or said second air passage is open and said first and third air passages are closed to admit only smoke from said combustible material to said mouthpiece, or said third air passage is open and said first and second air passages are closed to admit only air carrying volatile substances to said mouthpiece, or said second and third air passages are each partially open and said first air passage is closed to admit a mixture of smoke and air carrying volatile substances to said mouthpiece.

Claim 8

The smoking device of claim 5 wherein said volatile substances comprise nicotine.

Claim 9

The smoking device of claim 6 wherein said volatile substances further comprise aromatics.

Claim 10

The smoking device claimed in claim 5 wherein said area comprises first elements in close proximity with said combustion chamber, said first elements carrying the least volatile of said substances, and second elements more distal from said combustion chamber, said second elements carrying the most volatile of said substances.

Claim 11

The smoking device claimed in claim 5 wherein the combustion chamber side of said wall is furrowed by a plurality of grooves shaped and dimensioned to aerate said combustion chamber.

Claim 12

The smoking device of claim 5 wherein said air-intake conduit comprises a plurality of short sections joined together with a heat-sensitive bond.

Claim 13

The smoking device claimed in claim 10 wherein each section comprises heat-absorbing areas projecting into said chamber; and further comprising heat dissipating areas projecting into said conduit.

Claim 14

The smoking device of claim 5 wherein said means for selectively opening and closing said air passages include screw-like threads.

Claim 15

The smoking device of claim 12 wherein said means for selectively opening and closing said air passage further includes a spring-loaded obturator.

Claim 16

The smoking device of claim 5 wherein said means for forming said first, second and third air passages are holes.

Claim 17

A smoking pipe which comprises: a head; a stem having a channel therethrough in communication with said head; a separable, heat-resistant bowl inserted within said head and capable of holding a combustible material; volatile substances applied on the outside walls of said bowl; said bowl having means to form a first air passage which is between said bowl and said stem, said bowl and said head having means to form a second air passage which goes past the volatile substance and is between them and said stem, said head having means to form a third air passage communicating directly with exterior air; and means for selectively opening and closing said air passages, whereby said first air passage may be opened and said second and third air passages may be closed to admit only smoke from said combustible material, or said second air passage is open and said first and third air passages are closed to admit only air carrying volatile substances to said mouthpiece, or said third air passage is open and said first and second air passages are closed to admit only pure air to said mouthpiece, or said second and third air passages are each partially open and said first air passage is closed to admit a mixture of smoke and air carrying volatile substances to said mouthpiece.

Claim 18

A smoking pipe which comprises: a head; a stem having a channel therethrough in communication with said head; a separable, heat-resistant bowl inserted within said head and capable of holding a combustible material; volatile substances applied on the outside walls of said bowl; said bowl having means to form a first air passage which is between said bowl and said stem, said bowl and said head having means to form a second air passage which goes past the volatile substance and is between them and said stem, said head having means to form a third air passage communicating directly with exterior air; and means for selectively opening and closing said air passages, whereby said first air passage may be opened and said second and third air passages may be closed to admit only smoke from said combustible material, or said second air passage is open and said first and third air passages are closed to admit only air carrying volatile substances to said mouthpiece, or said third air passage is open and said first and second air passages are closed to admit only pure air to said mouthpiece, or said second and third air passages are each partially open and said first air passage is closed to admit a mixture of smoke and air carrying volatile substances to said mouthpiece.
