(Cl. 131-198 This invention relates to improvements in smoking 2,944,554 Patented July 12, 1960 The inner vents are carried by a coupling member which removably joins the stem and bowl sections of the article together at their inner ends, and is rotatable with respect to the bowl section. as hereafter explained.

The coupling also includes a solid surface surface ad -=l jacent the sides carrying the inner vents, which separately,

articles such as smoking pipes and holders for cigarsand cigarettes.

It has been found that some ,of thevarious forms of smokefiltration-presently available are ineificient and incapable of preventing deleteriousrtars :in the form of vapors and toxic fumes from penetrating the mouth and thence the lungs of the smoker. Further, smokers havev always been bothered by the sharp bite orburn of hot smoke as itjenters the. mouth particularly when the tobacco-in. the cigar, cigarette .or pipe has been nearly consumed. A

Accordingly, the present invention has as a principal object the elimination of the heretoforeobjectional bite or burn which object results in a coolsmoke; which is more enjoyable to the smoker. Additionally, the present invention has as a principalobject-the reduction of tars and other similar substances which otherwise would reach the mouth of the user. 1

It hasbeen found-that by bringing a minutestre'amjof outside air into the smoking article to the smallest possible diameter of smoke flow-in a direct line to the mouthpiece, a thorough mixing of air and smoke is obtained-thus-rereleasably engages the inner aperture of the outer vent to close communication therethrough.

Other objects and'advantages will become apparent upon reference to the accompanying specification and drawings. in which characters of reference represent corresponding parts in the several views.

As 1 indicated in'se'ction and by thedotted lines, the holder A is bored through the center thereof to form t a smoke duct 7 communicating the bowl 5 with the duoing the heat of the smoke and condensing the'vapors carrying tars' and other foreign materials. Further, it has been found that by removing this condensate from the line of smoke flow to the smokers month by Y smallest cross sectional area of flowjthroughfthej stem W in a direct line to the mouthpiece, and by further prothoroughly mixing with and cooling the Smoke". Asflle viding a condensate trap in the'botto'm of the mouthpiece between the vent and the bit to remove the condensate and foreign matter which results from the cooling process from the smoke stream.

. Additionally, it is an object'of the invention to provide an article for smoking in accordance with the above invention which also has a means for selectively varying the quantity or rate of air flow to the smoke duct through the vent so that the smoker can regulate the mixing process according to his individual taste.

A still further object is to provide a smoking article according to the above invention having a means by which it may be converted to conventional use.

These latter objects are accomplished by providing a smoking article having a minute outer air vent formed through the top of the mouthpiece normal to the smoke duct adapted to be separately, releasably engaged with three inner vents having Ibore diameters of various sizes, the largest of which substantially corresponds in dimension with the bore diameter of the outer vent.

mouthpiece 3 of the holder. Disposed vertically in the holder and at right angles to the smoke duct 7 is a minute air vent 9 opening communication between the atmosphere and the smoke duct 7 at its smallest cross section of smoke flow in a direct line to the mouthpiece.

At point 11 the bore diameter of the smoke duct abruptly increases and extends longitudinally topoint 13 where it sharply decreases to form a trap 15 below the line of smoke flow to collect the foreign matter'and condensate filtered from the smoke. I I

Thus, when the smoke is drawn through the smoke duct 7 of the holder A, air is drawn simultaneously through the air vent 9 and turbulently contacts; the smoke at its point of narrowest flow through the holder smoke is cooled the moisture Y content of the smoke-is condensed and thecondensate carrying" foreign material filters into the condensate trap 15 where it is retained throughout the smoking operation.

. Referring now to Figures 3 4, 5 and 6, there is illustrated a second embodiment of the invention and B .showing a pipe, having a shank 19 and a mouthpiece 21 having a bit 23 as shown in Fig. 3. Smoke duct portions 25. and '25 are formed through both the shank and mouthpiece communicating the bowl 27 with the mouthpiece 23 by reason of an insert coupling 29 which joins the shank 19 and mouthpiece 21. The coupling has a smoke duct 31 therethrough axially aligned with the ducts is snugly, removably nested in a socket in the connecting end of the mouthpiece 21. The circular plug 35 snugly, removably and rotatably nests in a socket in the connecting end of the shank 19. The outer end of trap 59 forms a shoulder 55 which positions the innenend of the rectangular plug 33. The opposite end 37 of plug 33 and outer end 39 of mouthpiece 21 are in alignment and abut the shoulder 41 of the shank 19. Thus, when the pipe B is assembled, the coupling 29 is'completely hidden from view.

As is better seen in Figs. 4 and 5, the rectangular plug of the coupling is provided with three minute radial vents 43, 45, and 47 with bore diameters of different dimensions, all of which have inner apertures intersecting the smoke duct 31 at the same location. These inner vents are formed through adjacent sides of the rectangular plug 33 normal to the smoke duct 31, and separately, releasably engage a minute vertical outer air vent 49 which has a bore diameter substantially as large as that of the largest inner vent 47. The inner vents carried by the releasable rectangular plug permit the flow of air from the atmosphere to the smoke duct 31 selectively in three different volumes and rates of flow. Thus, the smoker can vary the intake of air according to his taste.

The rectangular plug 33 also includes a solid side 51,

opposite the side of the plug containing the middle inner vent 47, which separately, releasably engages the inner aperture of the outer air vent 49 to close communica- 'tion between the atmosphere and the smoke duct. As is obvious, by eliminating the venting operation, the pipe is converted for conventional use.

Adjacent the inner end of the rectangular plug 33, the diameter of the smoke duct increases at 53 Where it is slightly smaller in cross section than the exterior of the rectangular plug to form shoulders 55 for abutting the inner end of the plug. This increased bore diameter extends to point 57, where it abruptly decreases forming a trap 59 in the bottom of the mouthpiece 21 below the line of smoke flow for collecting foreign matter and condensate from the smoke.

When any inner vent is engaged with the vertical outer vent 49 in the stem, the operation of the pipe is the same as that of the holder in Fig. 1. Air is drawn from the atmosphere to the smoke duct 31 through the vent 49 cooling the smoke at its smallest cross sectional area of flow in a direct line to the bit 23. The smoke vapors are condensed and the condensate then flows into the trap 59 between the vent 49 and the bit 23.

In this embodiment, when the user desires a different volume of air to mix with the smoke, or to change the rate of air flow, the rectangular plug 33 is removed from its socket, and the vent selected, raised to the top of the plug by rotating the circular plug 35 in its socket. By plugging the coupling 29 back into the stem, communication is again established between the atmosphere and the smoke duct 31 through the vent chosen. A like procedure is followed to convert the pipe to conventional smoking by raising the solid side 51 of the plug 33 to the top.

Also, other variations of air intake can be made by turning the mouthpiece 21 with respect to the shank 19 when the pipe is in assembled arrangement. With the mouthpiece 21 so inverted, the flow of air through the vent 49 is upward from the underside of the stern and difierent mixing results are obtained.

As is apparent, whether the pipe is used in the conventional manner, or the venting operation is from the underside thereof, the condensate trap 59 is still available for the depositing of foreign matter which may form p p Although I have described the invention in rather particular detail forpurposes' of clarity of understanding through reference to illustration and example, it is understood that various changes and modifications may be practiced within the spirit of the invention and the scope of the appended claims."
