Abstract
Abstract A smoking article which may be a pipe, cigar or cigarette holder has a removable stem or bit. The bit has a mouthpiece and tenon at opposite ends and is provided with separate air and smoke passages terminating at a mixing chamber at the mouthpiece end of the bit. The air passage extends from one side of the bit where there is a lateral opening. A movable slide valve member covers the lateral opening for adjusting the size of the opening and consequently the relative amount of air and smoke drawn through the bit. One smoke passage extends axially through the tenon end of the bit and is then divided into two branch passages which open into the mixing chamber. The air passage is located between the two branches. A slide valve carried upon the bit has a tapered opening operable over the air passage inlet to control not only the passage of air but the amount of air delivered. There is no mixture of air with smoke until it reaches the mouthpiece end of the bit, when it mixes, and cools and dilutes the hot smoke. The bit thus provides a cool and dry smoke.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
200 words
A bit for a smoking article, comprising an elongated generally cylindrical body having a cylindrical tenon at one end for engaging in bore means in said article, said body having a mouthpiece at its other end, said mouthpiece having chamber means for mixing smoke and air therein, said chamber means having an opening at the end of the mouthpiece for permitting a mixture of smoke and air to pass therethrough, said body having a smoke passage extending axially of the tenon to a point inside said body and a pair of laterally spaced branch smoke passages extending from said passage at said point to an inside wall of said chamber means for permitting smoke from said smoking article to be conveyed through said passages to said chamber means, said body further having an air passage extending obliquely between said inside wall of the chamber means and a side of said body, and terminating in a lateral opening thereat for permitting air to pass into said mixing chamber means, whereby suction applied at the end of the mouthpiece applies pressure equally in said air and smoke passages to draw smoke and air into the mixing chamber means for cooling the smoke.
Claim 2
Dependent Claim
200 words
A bit for a smoking article, comprising an elongated generally cylindrical body having a cylindrical tenon at one end for engaging in bore means in said article, said body having a mouthpiece at its other end, said mouthpiece having chamber means for mixing smoke and air therein, said chamber means having an opening at the end of the mouthpiece for permitting a mixture of smoke and air to pass therethrough, said body having a smoke passage extending axially of the tenon to a point inside said body and a pair of laterally spaced branch smoke passages extending from said passage at said point to an inside wall of said chamber means for permitting smoke from said smoking article to be conveyed through said passages to said chamber means, said body further having an air passage extending obliquely between said inside wall of the chamber means and a side of said body, and terminating in a lateral opening thereat for permitting air to pass into said mixing chamber means, whereby suction applied at the end of the mouthpiece applies pressure equally in said air and smoke passages to draw smoke and air into the mixing chamber means for cooling the smoke.
Claim 3
Dependent Claim
52 words
A bit as defined in claim 1, further comprising slide valve means on said body for adjusting the size of said lateral opening to regulate the relative quantities of smoke and air passing into said mixing chamber means and including tapered axially extending slot means operable over the air passage lateral opening.
Claim 4
Dependent Claim
66 words
A bit as defined in claim 1, wherein said smoke and branch passages are disposed in a first diametral plane of said body, and wherein said air passage is disposed in another diametral plane intersecting said first diametral plane and so that the air passage extends in said body between the branch passages and opens at said inner wall of the chamber between the branch passages.
Claim 5
Dependent Claim
62 words
A bit as defined in claim 1, wherein said body has means providing a recess in said one side thereof, said lateral opening being located at said recess means; and an apertured valve member slidably disposed in said recess means for adjustably opening and closing said lateral opening to regulate the relative quantities of smoke and air passing into said mixing chamber.
Claim 6
Dependent Claim
33 words
A bit as defined in claim 4, wherein said recess means includes dovetailed edges, said valve member being a plate having lateral beveled edges engaged with the dovetailed edges of the recess means.
Claim 7
Dependent Claim
32 words
A bit as defined in claim 5, further comprising means in the recess means and on the plate for cooperatively holding the valve member in any selected position in the recess means.
Claim 8
Dependent Claim
74 words
A bit as defined in claim 1, wherein said body has means providing a cylindrical recess, said lateral opening being located at said recess means; and a cylindrical valve member rotatably engaged on said body in said recess means, said valve member having a slot located so that rotation of the valve member adjustably opens and closes said lateral opening to regulate the relative quantities of smoke and air passing into said mixing chamber.
Claim 9
Dependent Claim
93 words
A bit as defined in claim 1, further comprising valve means on said body for adjusting the size of said lateral opening to regulate the relative quantities of smoke and air passing into said mixing chamber, said smoke and branch passages being disposed in a first diametral plane of said body, said air passage being disposed in another diametral plane intersecting said first diametral plane and located so that the air passage extends in said body between the branch passages And opens at said inner wall of the chamber between the branch passages.
Claim 10
Dependent Claim
48 words
A bit as defined in claim 8, wherein said valve means comprises means providing a recess formed in said body, said lateral opening being located at said recess means, and an apertured valve member slidably disposed in said recess means for adjusting the size of said lateral opening.
Claim 11
Dependent Claim
39 words
A bit as defined in claim 9, wherein said recess means extends longitudinally of said body and has dovetailed edges, said valve member being a plate having lateral beveled edges engaged with the dovetailed edges of the recess means.
