(Cl. ISI-200) 6 Claims. l

The present invention relates to tobacco smoking devices, such as pipes, cigarette holders and the like.

An object or" the invention is to provide an improved smoking device having a smoke chamber with thin flexible walls arranged to permit eX- pansicn and contraction of the chamber during smoking, the chamber also forming a smoke reservoir.

Another object is to provide a smoking device in which the smoke chamber forms a conduit through which smoke passes and in which the thin nexible walls are so arranged as to present an extended smoke-contacting surface for cooling the smoke and for trapping liquid particles and dust.

Still another object is to provide a smoking device in which the nexible walls of the smoke chamber are formed of thin, smoke-impervious material, such as rubber.

A further object is to provide a simple and inexpensive flexible member readily applicable to a ypipe or the like to form the thin flexible walls of a smoke chamber.

The invention fur-ther consists in the several features hereinafter described and claimed.

In the accompanyingdrawings, illustrating certain embodiments of the invention,

Fig. 13 is a View similar to Fig. 12, but showing the ilexible tube collapsed'by the application of suction. Y

Referring to Figs. 1 'to 5 of the drawings, ii) designates a Vpipe bowl adapted to receive a charge of ltobacco to be smoked, and H designates Va `tubular stern detachably secured to the bowl. The stem comprises separable sections l2 and i3, the former having a frictional lit in the bowl, and the latter having a mouthpiece portion or bit Il. The stern. sections l2 and i3 have respectiveaxial bores l5 and le therethrough,- the latter bore, if desired, having a reduced portion il at the bit. The stem sections are separably connected, as by providing the section I3 with a reduced iront end or nipple i8 frictionally fitting in a counterbore I9 'formed in the rear end of the section l2. In some instances, the section i2 may be made integral with the bowl. The bowl and rstem may be lformed of any usual materials, such as wood and hardened plastics.

Extending longitudinally in the bore i5 of the stem section I3 is a tube 20 with thin, limp, flexible walls, like these of a toy balloon, the tube formed of thin `rubber or rubber-like material. In some instances, the tube may be formed of certain other materials such as cellophane. Before its insertion, the flexible tube has the appearance .shown in Fig. 2, and comprises an intermediate portion 2l and reduced end portions 22 and 23. The intermediate portion 2l is conu siderably larger in diameter than the stern bore i6, and the reduced end portions 22 and 23 preferably have respective terminal beads 2d and 25. AIf desired, the reduced end portions of the tube may have thicker walls than the intermediate portion, as shown in Fig. 2. The ilexible tube 2@ is inserted 'into the lstem bore I6 from the large end thereof, the tube being folded or wrinkled in any suitable configuration, Asuch as that shown in Fig. 4 or Fig. 5, to pass into the bore. The reduced rear end 23 of the tube is passed through the reduced rear portion I l of the stem bore, and the end bead 25 of the tube expands to confine or lock the beaded fend in the stem. Preferably, although not necessarily, the stem has an annular rabbe't or cham'fer 2E at its rear end to receive the expanded bead. The front end 22 of the tube is stretched slightly and folded back over the reduced front end portion l of the stein section I3, the bead 24 fitting in an annular groove 21 formed about the stem portion l 8. The

stem portion I8 is then pressed into the front stem section I2, and the pipe is ready for use.

When the pipe is in use, suction applied to the stem by the smoker will draw smoke through the flexible tube 20, causing transverse contraction or collapse of the folded or wrinkled portion of the tube by differential pressure and somewhat constricting the smoke passage but not enough to cause hard drawing. The air pressure in the space between the tube and the stem collapses the tube when suction is applied to the tube by the smoker. In its travel the smoke contacts the extended inner surface of the flexible tube, thus cooling the smoke and also providing a filtering or cleaning action on the smoke, liquid particles and dust being deposited on the tube walls. Upon release of suction the flexible tube expands by reason of its resiliency, drawing in smoke from the bowl and in effect prolonging the suction action. The flexible tube forms a smoke reservoir in which the smoke is cooled and from which smoke is drawn at the next application of suction by the user. The pipe thus draws easily, and because of the expansion and contraction of the tube the lighted tobacco burns smoothly and is not likely to be prematurely extinguished. The cooling of the flexible tube occurs not only by radiation from the relatively large surface area of the tube and by contact with the stem section I3, but also by air which is admitted into the expansible tube from the mouthpiece.

The flexible tube 20 can be easily removed for cleaning, and the large diameter passages in the pipe stem also facilitate cleaning. Since the flexible tube is relatively inexpensive it is feasible to provide a new tube instead of cleaning the old one.

The invention may also be incorporated in cigarette holders and cigar holders. If desired, the pipe stem of Fig. 1 may be used as a cigarette holder.

The modified f orm of pipe stem (or cigarette holder) 3l shown in Figs. 6 and 7 comprises a front end section I2 with an axial bore l5, a mouthpiece section 32 with an axial bore 33, and an intermediate section or barrel 34 with an axial bore 35. The barrel is detachably secured to the end sections, as by frictional fits, the end sections having respective counterbores I9 and 33 to receive reduced opposite end portions 3'I of the intermediate section. A flexible tube 38, generally similar to the tube 20 of Fig. 2, is disposed in the barrel 34 and has reduced beaded ends 39 folded back over the reduced ends of the barrel, these reduced ends having annular grooves 40 to receive the beads. In some instances the intermediate section or barrel 34 is provided with a plurality of radial Ventilating openings 4I to improve cooling and to facilitate expansion and contraction of the exible tube. If desired, the pipe stem section I3 of Fig. 1 may be similarly apertured. The barrel may be formed of various materials, such as wood, metal and hardened plastics.

The device of Fig. 6 is similar in use to the device of Fig. l, the exible tube 38 expanding and contracting during smoking, and forming a trap for liquid particles and dust.

The modified form of pipe stem (or cigarette holder) I shown in Fig. 8 includes a front end section 52 having an axial bore 53 and a reduced rear portion 54, here shown to have an annular groove 55. The stem further includes another tubular section 56 with an axial bore 5l, the front end of the section 56 frictionally fitting over the reduced end 54 of the front section 52. The section 5B may be otherwise similar in construction to the stem section I3 of Fig. l, or it may be an intermediate member or barrel similar to the barrel 34 of Fig. 6.

A thin-Walled exible tube 58, similar to the tube 20 of Fig. 2, or the tube 38 of Fig. 5, is disposed in the stem section 5B and has a reduced beaded end 59 stretched over the reduced rear end of the front stem section 52. The rear end of the flexible tube may be secured in a similar manner, or it may be secured in the manner shown in Fig. 1. The smoke passage in the flexible tube consists largely of slit-like portions formed by the folds of the tube.

Also secured to the rear end of the front stem section is a exible rubber nipple or cup 33 having a small rear opening 6I. The nipple is disposed in the front end of the flexible tube and serves to trap any coarse particles or gummy material passing out of the front stem section 52.

The device of Fig. 8 is similar in use to that of the device of Fig. 1 or Fig. 6, the cup or nipple providing an added filtering action.

The modified form of pipe shown in 9 to 13 comprises a tobacco-receiving bowl 'Ill having a tapered side outlet 'IL A tubular stern section l2, such as of wood, has a conical metal end ferrule 'i3 frictionally fitting in the bowl outlet ll, the ferrule having a reversely turned conical portion 'I4 which provides a flaring opening for the tubular stem section. By this construction, burning of the stem section is avoided, and the conical end of the ferrule prevents blocking of the stem opening when tobacco is pressed into the bowl. The stem section 'I2 has a reduced cylindrical intermediate portion 'I5 on which frictionally ts the front end of a generally cylindrical barrel 'I5 of metal or hardened plastic. The stem section has a reduced cylindrical end portion 'I'I smaller in diameter than the intermediate portion 'I5 and adapted to frictionally receive thereover a rigid nipple or cup 18 having a small rear opening i3. This cup serves to trap any solid or gummy material passing out of the stem section 'I2 and also serves as a sleeve to frictionally hold thereon the front end of a thinwalled, limp, iiexible tube 8B, such as of rubber, extending longitudinally within the barrel i5. The rear end of the tube frictionally fits over a cylindrical sleeve 8l, such as of metal or hardened plastic, which frictionally fits over the reduced cylindrical front end portion 32 of a tubular mouthpiece 83. The rear portion ofthe barrel is made resilient as by forming longitudinal slots 84 therein, and frictionally fits in an annular groove or channel 85 formed in the mouthpiece concentrically of the reduced end portion 82.

In assembling the pipe, the ends of the flexible tube are applied to the cup 13 and sleeve 8l, and the cup is then pressed over the end portion 'I'I of the stem section 12. The barrel 'IB is then passed over the tube and is pressed onto the stem section 12, the intermediate portion of the tube being loose or slack in the barrel. The split rear end of the barrel is then compressed by the fingers to hold the sleeved rear end of the tube, and the mouthpiece is pressed into the sleeve 8I, the split end of the barrel frictionally fitting in the groove to retain the sleeve in its compressed condition.

When the pipe is in use the applicationof suction will cause collapse or deflation of the thin-Walled flexible tube, as to the folded condition shown in Fig. 13, leaving a restricted or slit-like smoke passage. A suicient suction will bring the opposed tube walls together, leaving constricted smoke passages at the folds. The space about the outer side of the tube communicates with the atmosphere by way of the barrel slots 84. During smoking the reservoir-forming flexible tube 80 contracts and expands, thus providing a steadying or ballasting action and also cooling the smoke. The extended inner surface of the flexible tube also aifords a filtering action. The pipe is readily dissassembled for cleaning, and any gummy material collecting on the inner walls of the flexible tube can be easily washed olf. The cup 18 is also readily detached and cleaned.

The flexible tube 80 is here shown to be formed of cylindrical stock but if desired it may have an enlarged intermediate portion, such as the tube `of Fig. 2, in which event the enlarged portion will be folded or wrinked as exemplied in Figs. 4, 5, and 7.
