fl/QOLL C. F/GGE BY Z United States Patent M 3,152,596 AIR ADMITTING SMOKERS PRODUCT Carroll C. Figge, Batavia, Ill. Filed Feb. 12, 1962, Ser. No. 172,683 1 Claim. (Cl. 131-198) An important object of the invention is to cause a mixture of the smoke coming from the product with external air admitted to the space between the product and the smoker so that the air expands and as it does, it absorbs heat from a tube to the smokers mouth.

A further object of the invention is to cool the smoke from the article by admitting air from the outside of the tube or holder inserted in the smokers mouth so that the incoming cooler air reduces the temperature of the tube extending to the smokers mouth and is diffused in a mixing chamber with the smoke so that the smoke stream drawn therefrom is reduced in temperature and even the color of the smoke may be changed due to the mixture of the air with the smoke generated by the burning of the tobacco.

Other objects of the invention will appear in the specification and will be more apparent from the accompanying drawings, in which:

FIG. 1 is a partly sectional elevation of a cigarette to which a smoking tip is attached.

FIG. 2 is a similar view of the invention as applied to a cigarette having a separate holder with an air inlet and mixing chamber.

FIG. 3 is a part sectional elevation of a cigar and a separate holder therefor having a mixing chamber and an air inlet thereto; and

FIG. 4 is a sectional view of a portion of a pipe showing a shell or sleeve for connecting the bowl of a pipe and a mouthpiece therefor and for providing an air inlet and a graduated control therefor in a connector between the bowl and mouthpiece.

In many tobacco products, it is the present day boast that they produce a cooler and milder smoke meaning that the burning of the mixture is not so rapid, that the smoke is filtered, or that the mixture of tobacco is not too harsh as to be disagreeable or raw to any smoker.

In the present invention, this is overcome and the sensation of smoking is much improved by reducing the temperature of the gas, and by producing a mixture which is more smooth, pleasing and not as objectionable to most smokers.

Referring now more particularly to the drawings, FIG. 1 shows a cigarette with an attached overlapping tip 12 providing a chamber 14 spaced from the adjacent end so that tobacco 16 therein will not ordinarily come in contact with the lips or tongue of the smoker. Into this chamber 14 is inserted a tube 18 which has an angular cutoff 20 at the inner end, the outer end being inserted through and attached to the tip or mouthpiece, substantially at right angles to the wall of the tip 12 in any suitable manner. This tube may be of thin metal, paper, foil, a short quill, or any other suitable material, the inner end and the cut-off 20 being preferably located at about the center or diameter of the tip, and the tube may even form a stop for limiting the insertion of that end of the cigarette in the tip, or the tube may be inserted just at the end of the cigarette.

The object of the specific location of the cut-off 20 of the tube at the center of the chamber 14 is to insure that it will function as a mixing chamber for the smoke drawn inwardly from the cigarette and for the air drawn in wardly from the outside air surrounding the tip so that the smoke and air are thoroughly intermingled and mixed in the chamber 14. Drawing the smoke through the tip causes the tube and its cut-off to act very much like a 3,152,596 Patented Oct. 13, 1964- syphon, the outer or cooler air being drawn into the warmer and usually somewhat colored smoke so that the effect is an intermingling of the outer cooler air and the inner heated air from the cigarette which forms a cooler and milder mixture for the smoker drawn from the tip. When the smoking is finished, this tip 12 with the tube 18 therein is commonly discarded with the remaining attached extremity of the cigarette 10, and therefore constitutes a throw away product.

In this construction, the outlet is located at the approximate radial center of the mixing chamber, and discharges toward the mouthpiece causing cold air from the outside to mingle with the smoke drawn from the smoking article, cooling and producing a milder mixture of gases for the smoker. In the form of the invention as shown by FIG. 2, a cigarette 22 is inserted at the end of a tip or cigarette holder 24 which commonly has a mouthpiece 26 spaced more or less from the inserted end of the cigarette and forming a mixing chamber 28 interposed between the cigarette and the mouthpiece.

Into this chamber, an air admission tube 30 is inserted which may also be located to limit the insertion of the cigarette into the mouthpiece, and also it has an angular inner end 32 which is bent to extend from the cigarette into the chamber 28 at the approximate center of the chamber and like the former air inner inlet tube 18 to admit outside air at the center of the cigarette through the mouthpiece, and thereby to induce a flow of air through the tube by drawing smoke through the mouthpiece.

This construction likewise causes an intermingling of the outside or cooler air with the smoke or gases from the cigarette, and the consequent cooler and milder mixture of gases at the mouthpiece and to a smoker.

A similar construction is shown in FIG. 3 as applied to a cigar 34 having an end opening 36 for the passage of smoke. A mouthpiece 38 is tightly applied to the end of the cigar, and a short stem 40 is commonly found for engagement by the lips and teeth of a smoker. In this mouthpiece, there is a mixing chamber 42 and projecting inwardly from one side of the mouthpiece is a short air inlet pipe 44 secured in the wall of the mouthpiece and having an inner bent end 46 which extends from the end of the cigar into the center of the mixing chamber 42 and injects cool air from the atmosphere to intermingle with the smoke drawn from the cigar around the end of the pipe 46 into the mixing chamber, thereby cooling and making a milder mixture of gases for the mouth of a smoker.

A pipe is shown in FIG. 4 having a bowl 48 with a recess 50 in which tobacco to be smoked is placed with a passageway 52 leading from the bottom of the recess. It has a stem terminal 54 which preferably registers in size with a separate mouthpiece and stem 56 which is attached thereto in the ordinary pipe by sticking one into the other so that a stern passageway 58 in the mouthpiece registers with the passageway 52 in the stem. In the present invention, the two stern sections 54 and 56 may be joined by a metal sleeve 60 which makes a sliding fit and tightly connects them both.

At one side of the sleeve is a tube 62 extending inwardly to the center of the space forming a mixing chamber 64 in the sleeve. At the other side of the sleeve 60, a pintle 66 having a pointed tip 68 is threaded through the side of the sleeve 60 and adapted to be inserted more or less into the end of the air tube 62 by a head 70.

With this construction, air is drawn from the pipe bowl recess 50 through the passageway 58 of the mouthpiece stern and through the mixing chamber 64 where the air tube 62 extends to the center of the space forming the mixing chamber 64 so that the smoke from the bowl injects the cooler air into the mixing chamber and causes a thorough intermingling of the gases with the cooler outside air. The amount of outside air may be varied by inserting the tip 68 of the pintle more or less into the open end of the air tube 62, or if desired, it may be closed entirely which will give a pipe smoker a mixture of smoke of the greatest heat and strength as compared with any possible variation thereof.

With all of these constructions, the operation is similar: drawing smoke through the mouthpiece will cause it to be drawn through a mixing chamber to which a small stream of air is admitted for causing an intermingling of the smoke with the cooler aid which forms a cooler and milder mixture of gases which pass to the mouth of a smoker. In one case, means is shown for closing off entirely or admitting a predetermined amount of air to the mixing chamber which will correspondingly vary the mixture of the cool air With the hotter gases from the article smoked.

While this construction for varying the amount of air is shown only in connection with a pipe, it may also be supplied in the same or a slightly different form to each of the constructions shown. In some cases like that of a cigarette, an air inlet to the mixing chamber is preferably adopted to suit the enjoyment of the majority of smokers and thus to form a predetermined cooler and milder mixture of gases for the particular smoke in question.

While I have described a preferred construction in some detail, it should be regarded as an illustration or example rather than as a limitation or restriction of the tobacco forming a mouthpiece and an inner mixing chamher to the end of the tip and free from tobacco, and if short hollow tube extending at about right angles through the wall of the tip to the central portion of the chamber between its ends and engaging the end of the tobacco body therein to form a stop limiting its insertion into the mouthpiece and the inner end of the tube being located near the center of the inserted tobacco body, and having an angular cut-01f at its inner end to inject air from the outside into the chamber in smoking to mix it with smoke from the tobacco and to produce a cooler and milder smoking mixture at the mouthpiece.
