`10 Claims.
`(Cl. 1228-208)
`
`invention relates to a smokeless non-
`The present
`tobacco cigarette and has for an object to provide a safe
`and harmless means for and method of smoking by re-
`placing burning tobacco and paper with heated, moist,
`flavored air; -or by inhaling warm medication into the
`lungs in case of a respiratory ailment under direction
`of a physician.
`Another object of the invention is to provide an article
`of manufacture resembling a cigarette ‘by which air may
`be drawn through a porous substance of a cartridge
`which has been moistened with a chemically harmless
`flavoring preparation, combining moisture and taste fol-
`lowing which the moist and flavored air passes through a
`section of the device heated by a suitable heating ele-
`ment -so that warm, moist and flavored air is drawn into
`the mouth and if desired into the lungs of the user.
`A further object of the invention is to provide a smoke-
`less non-tobacco cigarette in which provision is made for
`circulating the fluid around the heating element in a tur-
`bulent manner to suitably raise the temperature of the
`inhalent mixture, with the purpose that the temperature
`of the flavored air may approximate that of ‘cigarette
`smoke.
`
`A further object is to insulate the heat source so that
`the “cigarette” may be held in the fingers without dis-
`comfort to the user’s hand.
`With the foregoing and other objects in view, the in-
`vention will be more fully described hereinafter, and will
`be more particularly pointed out in the claims appended
`hereto.

`{FIGURE 10 is a side elevational View of a form of

`Referring -more particularly to the drawings, 15 desig-
`nates an external tube made preferably
`the size, color
`and form of a cigarette, such tube having an outer end
`portion 16 and an inner end portion 17.
`Subdividing the interior space of the external tube is
`an internal shoulder 18 which is preferably closer to the
`outer end portion 16 than to the opposite inner end p
`tion 17, thus dividing the tube into relatively short and
`substantially longer chambers.
`The tube 15 is supplied at the inner end portion =17
`
`60
`

`
`with internal threads 19 or some other means of connec-
`tion for a mouthpiece as later described.
`In the outer end portion 16 is detachably fitted a flavor
`cartridge 20 o-f some suitable absorbent material, pref-
`erably having longitudinal spaced passages 24]
`there-
`through of a small diameter. The cartridge 20 is abutted
`against the outer edge of the internal shoulder 18 and is
`of an external diameter to fit snugly into the outer end
`portion I6 so that it will be held therein by friction or
`other suitable means.
`Within the more forward chamber of the outer tube 15
`is received a tubular liner 22 preferably of insulating ma-
`terial and having an internal wall 23 of a form and
`character to tumble the air or create turbulence therein.
`This internal Wall may be spiralled or rifled as indicated.
`A mouthpiece Z4 is aflixed to the inner end portion 17
`of the tube .15 in any appropriate manner, preferably
`udetachably as by external threads 26 on the hollow shank
`25 of
`the mouthpiece which mate with the internal
`threads 19 in the inner end portion of the outer tube 15.
`As shown in [FIGURE 2,
`the free outer end of the
`hollow shank 25, when fitted home in the outer tube, will
`encounter and push the insert 22 against the inner -wall of
`the internal shoulder 18 thus holding the insert 22 im-
`movably in place.
`The hollow shank 25 will preferably have an outstand-
`ing shoulder 27 «forwardly of the threads 26 to engage
`the inner end of the tube 15 in the completely assembled
`position of the mouthpiece 24 relatively to the outer
`tube 15.

`
`As best seen in FIGURE 6 showing a cross-section
`«through the hollow shank portion 25 of the mouthpiece,
`a spider formation is shown providing air draft spaces
`28 between the hollow shank 25 and an inner ring 29
`spaced inwardly from the hollow shank 25 and con-
`nected therewith by radial arms 39. The air draft spaces
`28 communicate with the suction orifice 40 of the mouth-
`piece at the inner end and at the outer end with the space
`circumscribed by the inner wall 23 of the -tubular in-
`sert 22.
`
`Within the inner ring 29 is a threaded electric socket
`30 and forward-ly thereof a battery cavity 31 for detach-
`ably receiving a battery 32 having an inner contact 33
`and an outer contact 34 with a contact strip 35 between
`the inner contact 33 and the socket 30.
`The heating element is preferably a vacuum tube or
`bulb 36 having a screw plug 37 for detachable engage-
`ment with the socket 30. The screw plug 37 has an end
`contact 38 adapted to close against the outer battery con-
`tact 34. The bulb or tube 35, similar to a light bulb, is
`preferably elongated and of a diameter to fit within the
`insert 22 '
`as to provide an elongated
`heating passage t-hroughout the length of the bulb and
`around the complete circumference of the bulb 36.
`In assembly, the flavor cartridge 29 can be introduced
`Sud’ removed without regard to the other units of the
`evice.
`Before the mouthpiece 24 is assembled to the external
`tube E5, the hner 22 is slid through the open inner end
`portion of the tube until the outer end of the liner 22
`encounters the internal shoulder 18. The bulb 36 will
`be mounted to the socket 30 while the mouthpiece 24 is
`detached from the tube I5 whereupon the bulb 36 may
`be introduced into the insert 22 as the mouthpiece 24 is
`put into place and rotated to effect attachment of the
`mouthpiece to the outer tube 15. The final home posi-
`tion of the parts is indicated in FIGURE 2 in which the
`hollow shank 25 engages the inner end of the insert 22
`while the outer end of the insert is abutted against the
`internal shoulder 313.
`When the bulb 35 is assembled to the socket 30 its tip
`end 33 will engage the inner battery contact 313 and com-

`plete the circuit through the filament of the bulb 36 by
`the Contact strip 35. Thus the bulb 36 will be iliuminated
`or energized before assembly to the external tube 15.
`A The battery 32 is ‘removable so that when exhausted,
`a fresh dry battery may be substituted, access to the same
`being had by first unscrewing the mouthpiece Z4 and
`withdrawing the bulb 36 and subsequently removing the
`bulb 56 from its socket 30.
`The insert 22 is preferably of a ceramic material. By
`the act of inhalation through the mouthpiece 24, air from
`the ambient atmosphere is drawn in through the passages
`21 of the cartridge 2!} which has been impregnated with
`suitable flavoring material which is picked up by the in-
`haled air and such air then passes into the heating cham-
`ber -and is caused to How around the heating bulb 36, the
`heated and flavored air finally passing through the mouth-
`piece 24 into the mouth and also, if desired, into the
`lungs.
`The tumbling of the air around the heat source provides
`for uniformity of heat transfer while the insert 22 also
`serves to insulate the basic tube ‘i5 so that it does not
`become hot to the hand of the user.
`The cartridge 26) may be composed of a porous, mois-
`ture-holding substance such as felt or plastic sponge al-
`though there are many other materials which will serve
`the purpose.
`The impregnation will be by a harmless flavored chemi-
`cal compound. As suggested,’ such compounds may be
`solutions ranging from slightly mentholatecl water to a
`solution which would simulate artificially the flavor of
`Scotch whisky. Many other solutions and flavors may
`be employed.
`The outer tube may be of plastic, fiber glass or any
`other appropriate material.
`_
`The member 24 as shown in the drawings is shaped in
`the fashion of a mouthpiece but it is not necessary that it
`be so shaped. The tubular shape of the outer tube 15
`may be continued to the right hand end of the mouthpiece
`if desired to further the illusion of a cigarette.
`Some of the advantages of the invention are:
`(a) There is no open flame or fire and fire hazard is
`therefore eliminated.
`(b) Nothing is consumed so that there is no smoke,
`ashes or dirt.
`(c) Since the air which enters the lungs of the user
`comes into contact with only inert materials, there
`is nothing of an injurious nature being placed into
`the respiratory system of the user.
`(d) Heated medication for respiratory ailments may
`be induced into the lungs of a user of this invention
`should a physician feel the same desirable.
`(e) Persons who wish to smoke but have been ad-
`vised against such a practice by their doctor may
`use this invention to maintain the satisfaction of
`smoking without any of its disadvantages.
`(f) By changing the liquid employed to moisten the
`cartridge 20, a variety of tastes may be imparted _
`to the warm moist air which serves to duplicate the
`. smoking sensation.
`(g) The size and shape of the device according to this
`invention may approximate the size and shape of
`a cigarette; therefore its use will not call undue at-
`tention to the user. A white coloration of the basic
`tube 15 and mouthpiece will further add to this
`illusion.
`It is to be understood that various details of the ex-
`emplary structures chosen to illustrate the invention are
