l wawtok ab WM United States Patent US. Cl. 131-194 1 Claim ABSTRACT OF THE DISCLOSURE A cigarette holder having a socket for receiving a cigarette at the inlet end, a mouthpiece at the discharge end and a smoke cooling member between the two. The socket has a screw threaded engagement with the inlet end of the mouthpiece and the smoke treating member adjacent to the socket member. The smoke treating member consists of a plurality of smoke conducting tubes that are mutually spaced and contained within a housing member that is placed in the inlet end of the mouthpiece. The tubes are connected to apertured discs adjacent to the opposite ends of the member and communicate with chambers adjacent to each disc and are so arranged that smoke passing through the holder reverses direction twice before reaching the discharge end of the mouthpiece. A valve is provided in the chamber at the upstream end of the member and is arranged so that a cooling fluid such as liquefied gas may be injected and retained under pressure within the housing in the space surrounding the spaced tubes and between the apertured discs.

BRIEF SUMMARY It is well recognized that tobacco smoke contains ingredients which can be unpleasant to smokers, and in some cases harmful as well. It is also recognized that in general, the higher the temperature of the smoke, the greater will be the tendency thereof to be unpleasant and harmful.

It is an object of the present invention to provide a smokers device such as a cigarette holder with means for cooling the smoke drawn therethrough by providing a divided smoke path consisting of plural tubes that are mutually spaced and surrounded by a cooling medium and in addition, to cause the smoke to traverse a smoke treating member three times in a serpentine path as it passes through the same.

For a better understanding of the present invention, attention is directed to the accompanying drawing wherein:

FIG. 1 is a perspective view of a cigarette holder constructed in accordance with the present invention;

FIG. 2 is a central longitudinal section through the holder shown in FIG. 1;

FIG. 3 is a cross sectional view taken on the line 3-3, in FIG. 2, facing in the direction of the arrows;

FIG. 4 is a view similar to FIG. 3, taken on the line 44, in FIG. 2;

FIG. 5 is a view similar to FIG. 3, taken on the line 55, in FIG. 2; and

FIG. 6 is a view similar to FIG. 3, taken on the line 6-6, in 'FIG. 2.

DETAILED DESCRIPTION The device shown in the drawing may be assembled by sliding a smoke treating member having cylindrical shell 14 into a chamber provided therefor in the inlet end of the mouthpiece portion 19 after which the socket 20 is connected thereto by screw threads to occupy the positions shown in FIG. 2. The inlet end of the socket has an internal shoulder for limiting the insertion of a cigarette therein and providing a chamber between the unlit end of 'ice the cigarette and the inlet end of the smoke treating member. The central portion of the length of the smoke treating member consists of a cooling chamber having an apertured disc 13 at the inlet end and another apertured disc 16 at the discharge end, both discs being mounted in sealing relation with the internal wall of the shell 14. Mounted between the discs, and spaced from each other and from the internal wall of the shell are a plurality of smoke conducting tubes 14, 17 and 18, arranged so as to be parallel to each other and to the longitudinal axis of the cooling chamber and the holder. Each tube is mounted at the opposite ends thereof in sealing relation with each of the discs 13 and 16, and is in communication with an aperture in each of said discs. A third disc 2 is mounted at the inlet end of the shell 14 in spaced relation with the disc 13. A partition 10 is mounted in sealing relation between the discs 2 and 13, and with the internal wall of the shell providing smoke receiving chambers 3 and 9. The disc 2 is provided with an opening 1 as seen in FIG. 3, so that smoke may pass into the chamber 3. Similar smoke receiving chambers 6 and 7 are provided at the discharge end of the smoke cooling member and are defined by the discs 16 and 12 and the partition 8 which is mounted and sealed in the same manner as the partition 10. The disc 8 has a discharge opening 11 as seen in FIG. 6, which is arranged in diametrically opposed relation to the opening 1. A spring loaded valve 15 is mounted between the discs 2 and 13 by means of a casing or duct 21 and is adapted to provide means whereby a cooling medium such as liquefied gas for example, liquefied nitrogen, may be injected into the cooling chamber to occupy the space '5 under pressure and to surround the tubes therein.

In use, a cigarette is placed in the inlet end of the socket 20 until unlit thereof abuts the shoulder, and is lit in a conventional fashion. As the user draws on the mouthpiece end of the holder, smoke is drawn from the cigarette into the chamber in the discharge end of the socket 20, through the opening 1 into the smoke receiving chamber 3, through the plural tubes 4 shown in the lower portion of FIG. 2, into the chamber 6. The smoke then reverse direction and flows through the tubes 17 to the chamber 9 where the smoke then reverses direction a second time and flows into and through the chamber 7, through the opening 11, through the discharge end of the mouthpiece 19 and into the mouth of the user.

After being used, the smoke cooling member may be removed after the socket 20 is unscrewed from the mouthpiece 19, it being noted that the discharge end of the socket includes a shoulder portion adapted to hold the member in the holder between a similar shoulder in the mouthpiece, adapted to engage the discharge end of the member. As noted in FIGURE 2, the shell 14 is made from heat insulating material. The remainder of the cooling member may be made from metals which can be joined by soldering, welding or the like. The socket and the mouthpiece are made from materials conventionally used for that purpose. The cooling member may be charged by the smoker prior to using the holder, or the cooling member may be provided to the smoker in charged condition.

According to the above, it will be seen that smoke passing through the present holder will be cooled as it passes through the tubes 14, 17 and 18, and in the chambers 3, 6, 9, and 7, and by virtue of the reversing passage provided, the smoke will be divided into plural streams, assembled after each pass, and redivided as it is caused to reverse direction each time, thereby providing plural opportunities for the heat that is contained in the smoke to be extracted by the coolant gas in the cooling member thereby lowering the temperature of the smoke and caus- Ing condensation of tars and the like that may be en- ;rained therein.

Having thus described my invention, I claim:

1. A smoking device having means for holding tobacco 10 be burned at one end, a mouthpiece at the other end and a smoke conducting and treating member therebe- LWeen, said member including a casing connecting the :obacco holder and the mouthpiece and containing plural spaced smoke conducting conduits extending longitudilally thereof and in mutually spaced relation therein, neans comprising a pair of discs extending transversely )f the member, said discs being attached to opposite ends at said conduits and being supported in said member by Jeing attached at the peripheral portions thereof to a casng surrounding said discs and said conduits, said mem- 361' having means for retaining said casing therein, said :asing having chambers at opposite ends thereof whereby said discs are spaced from the ends thereof and providing :hambers adapted to direct the flow of smoke through the device, said casing having apertured Walls at the opposite ends thereof adapted to permit smoke to pass therethrough and partitions extending longitudinally of said chambers and extending thereacross, the discs having a plurality of apertures therethrough and said conduits being attached ;0 said discs so that smoke which may be made to flow through each aperture will flow through a conduit in communication therewith, the conduits being arranged to provide a serpentine path through said conduits and chambers in said casing from the tobacco holder to the mouthpiece, the end wall and the disc located nearer said tobacco holding member'having a duct having a spring loaded valve therein and extending axially therethrough whereby a fluid coolant under pressure may be forced through said duct and into said casing so as to surround said conduits in said member.
