3- Claims. (Cl. ISI-182).

This invention relates -to improvements in smoking articles and the like.

An object of the invention is to provide-a novel and improved cigarette holder which is engageable with a cigarette in such Ia manner as to make it a filtered cigarette. t

Another object of the invention is to provide a novel and improved cigarette holder which includes means for effecting compressment of the tobacco in a portion of the cigarette, so that the -compressed tobacco of the oigarette forms a lter for smoke, nicotine and tars, and other products o'f the smoking process.

A further object of the invention is to provide a novel and improved cigarette holder in which there isan opening for the reception of an end of a cigaet-te, and a slidable cigarette penetrating member which is disposed inside the 'housing of the holder, and adapted for being extended forward-ly so as to penetrate into the tobacco at the rearward end of the cigarette, thus expanding the tobacco outwardly radially, and compressing the tobacco, the arrangement being such that the smoke which flows rearwardly through the -cigarette on puffing by the smoker, is constrained to flow through the compressed tobacco, and thus to be filtered thereby.

Still another object lof the invention is to provide a novel and improved filter type cigarette holder in which the cigarette itself is made to become a. smoke lter, by having the rearward end yof the cigarette confined in a cylindrical housing, so that it cannot expand, and including an elongated shaft of substantial thickness which is carried on a smoke permeable support withinthe holder housing, the support being extensible forwardly so that its elongated shaft is `pushed into the confined end of the cigarette, `and of suicient thickness or r-adial dimension as to provide substantial radial Acornpressment of the tobacco, the shaft being constru-cted to block passage of smoke therethrough, so that the smoke must pass through the tobacco which is compressed, and is thus filtered.

These and other objects and advantages of the inven- -tion will become apparent lfrom the following description of a preferred embodiment thereof, as illustrated in the accompanying drawings, forming a part hereof, and in which,

Figure 1 is an elevational View of a cigarette holder according to the invention, with aV cigarettesdisposed therein.

In connection with the smoking of cigarettes, it has Ybecome increasingly apparent that the .public to a large extent, finds certain'advantages in filtration of thesrnoke before it reaches the mouth and'lungs of the smoker. Such filtration has heretofore been accomplished mainly by introduction of a tilter tip to the rearward end of the cigarette, which contains cellulose, cotton fibres, or other filtering material which is not of the same material as the tobacco itself. The present invention provides means whereby the ordinary unfiltered cigarette' may be its' own filter, and thus avoids the need for attachment of filter tips to the cigarette, or for useV of otherV auxiliary filtering materials in the path of the smoke. This is done by compressing the tobacco in the rearward end portion of the cigarette, and thus constraining the smoke to low through the compressed tobacco, taking advantage of its high degree of smoke'ltering action. A housing is provided, into which theA rearward end of the cigarette is inserted to .a substantial degree, and a movable penetration shaft is movably mounted inside th-e housing, so that on forward movement it penetrates into the tobacco and thus compresses it radially outwardly. The smoke must flow through the compressed tobacco, and is thus -ltered After smoking, the butt is ejectedby simple movable means.

The present invention thus provides for many advan- -tages in cigarette filtering, without need for complicated structural means or addenda to the cigarettes themselves for bringing this about..V In order to understand clearly `the nature of the invention, and the best means for carrying it out, referencem-ay now be had to the drawings, in which likenumerals denote similar parts throughout the several views.

As shown, there isla main 4cigarette holder housing generally indicated at 20, which in the form vshown may be generally cylindrical, tapering aty its 'rearward end portion to the lef-t of location Z6, to form a mouthpiece 2.8, the ytip of which is seen at 30. The mouthpiece 28 has .a passageway 32 formed therethrough, which opens upon the main Ibore 24 of the main housing7 and 'from Figures 1- and 2, it is-seen that a cigarette 10 may have its rearward endY portion inserted into the forward Vopening i6 ofthe main housing for a substantial distance Vinwardly of the forward end 18 of the main housing.

Inside the main housing bore 24 are two main yassemblies or members, namelythe cigarette ejector member 50, shown in detail also inFigure 6 apart `from the assembled device,.and the Itobacco penetratopcompresser member 52. The cigare-tteejector member 50 has a cylindrical body wall 62 secured atfits forward endto the forward wall 63, and open at its rearward end, thus defining a cylindrical bore 65 in whichis slidably disposedV the cylindrical bodyv wall 53 ol" the penetratorcompresser member 52.. As seen best in Figures 2 and 4, the front wall 63 of the ejector member 50 has a number of openingso formed therein to allow passage of air and smoke there through as indicated by the arrows in Figure 2, theopenings 66 being formed between the spider legs or ribs 64 remaining and the central wall portion or hub 68. A position adjusting knob 58is mounted on the pin 60- which in turn is seated ina socket formed in the wall 62 of the ejector member so as tobe movable therewith. As seen `best in Figures l, 2 and .4, the pinA 6@ is constrained to movement in the guide slot 92 formed in main outer housing 22', from a rearward position at which -the cigarette is insertable inthe holder, t-o full forward position at which the' cigarette is ejected from the holder, when the burning Iat 11 has progressed 3 for a suicient time, or the user is finished with smoking it.

The cigarette compressor-penetrator member 52 also has a cylindrical body wall 53 the outside diameter of which is substantially the same as the inside diameter of the ejector bore 65, with only sufficient looseness to permit easy slidable movement of the two

members

52 and 50 on each other without slippage. The member 52 also has a forward wall 57, provided with openings 84 between the spider ribs 86 and the central area or hub 88, for the free passage of air and smoke as indicated by the arrows in Figure 2. The rearward end of member 52 is open, to allow air and smoke to pass therethrough. A cigarette penetrator-expander or compressor shaft 72 is carried on the forward Wall of member S2, being either integral therewith, or mounted in any convenient manner, as by having its reduced rearward end 74 extending through an opening in the hub area 88 of the wall 57, and then peened over as shown to retain the shaft 72 for movement with member 52.

The forward end 73 of the tobacco compressor shaft 72, may be conveniently pointed to facilitate its entry into and expansion of the tobacco in the rearward end of the cigarette when it is moved to forward position, as

shown by broken lines at 72a in Figure 2. A knob 56 is mounted on a pin 54 seated in the wall S3 of the expander member S2, and extends through the motion limiting guide slot 94 formed in wall 22 of the outer housing, to permit easy adjustment of the position of the member 52. The length of the slot 94 is chosen to give the desired degree of penetration of the shaft 72 into the cigarette. As seen, there is a central opening 70 in the front hub area 68 of the ejector Si), to allow the pin shaft 72 to slide therethrough, and to aid in maintaining its axial orientation at all times.

In using the device, with the members 52 and Sii in retracted positions, as shown in Figure 2, the cigarette is inserted inside the front or ferrule portion 18 of the main housing, so that a substantial portion of the cigarette length is confined inside ferrule portion 1S as shown. The knob 56 which is the cigarette compressor actuating knob, is then pushed forwardly, causing the expander shaft 72 to enter the tobacco 14 of the cigarettc, displacing the tobacco radially outwardly as the shaft moves to position 72a, and thus compressing the tobacco in the annular space between the shaft 72a and the ferrule 18, and forming a long annular mass of densely packed tobacco rearwardly of location 16. The cigarette is then lighted as at 11, and it is apparent that the smoke must travel rearwardly through the more densely packed annular tobacco mass under ferrule 18, since the shaft 72 remains in the tobacco, and hence a considerable liltering action is obtained, the tobacco being more dense giving good filtration by blocking passage of impurities in the smoke, and holding them within itself. It is noted that the smoke can pass freely rearwardly due to the

openings

66 and 84. After the cigarette is smoked, it is simple to retract the knob 56, pulling out the shaft 72, and to push forward the ejecting knob 53, moving member 5t) forwardly, and ejecting the smoked cigarette from the holder. The ferrule 18 permits of good radial displacement of the tobacco by shaft 72, since there is support by ferrule 18 to hold the displaced tobacco.

For obtaining further or adjustable filtration, it is possible to increase or decrease the degree of insertion of the shaft 72 in the cigarette, and also by further insertion of the cigarette in the holder, or -lessening the insertion. By making the shaft 72 quite long, and the ferrule 18 correspondingly long, the degree of iiltration due to increased length of filtration path can be made of any degree at all as desired. Similarly, as shown in Figure 7, the shaft 72b may be made to thread at 73b into the central opening 71 in wall 57, and easily removable so that the dealer may sell it with several lengths of differing size of such shaft, to suit the needs of the smoker.

Also the diameter of the shaft 72 may be made in varying sizes, so that a higher or lower degree of radial displacement may be obtained to suit the smoker.

Although I have described my invention in specific terms, it will be understood that various changes may be made in size, shape, materials and arrangement without departing from the spirit and scope of the invention as claimed.
