CHARLES S. EVANS, O'F

CIGARETTE.

Application filed March 2 Be it known that I, CHARLES S. EVANS, a citizen of the United States, and a resident of Berkeley, county of Alameda, State of California, have invented a new and useful Cigarette, of which the following is a speci fication.

My invention relates to cigarettes.

An object of the invention is to provide a cigarette having an improved mouthpiece.

Another object of the invention is to provide a cigarette having an extensible mouthextension sleeve piece.

Another object of the invention is to provide a cigarette having a mouthpiece member normally loosely telescoped upon the body of the cigarette and adapted to be withdrawn to one end to form an extension mouthpiece in tight engagement therewith.

The invention possesses other objects and features of advantage some of which with the foregoing will be set forth in the following description where I shall fully explain the preferred form of my invention which is illustrated in the drawings accompanying and forming part of the specification. The novelty of the invention will be included in the claims succeeding the said description. It is understood that I do not limit myself to the showing made by the said drawings and description as I may adopt many variations within the scope of my invention as set forth in the said claims.

Referring to said drawings which appear in enlarged scale:

Fig. 1 is a side elevation of one form of the cigarette of my invention, a portion of the being broken away to show the construction. The sleeve is shown telescoped upon the body of the cigarette.

Fig. 2 is an end view of the cigarette shown in Fig. 1.

Fig. 3 'is a perspective view of the bushmg.

Fig. 4: is a view of the cigarette shown in Fig. 1, but with the sleeve member extended.

Figs. 5, 7, and 8 are side views partly in section of modified forms of my invention.

Figs. 6 and 9 are end views of the cigarette shown in Figs. 5 and 8 respectively.

Figs. 10, 11, 12, 13, 14, and 15 are side views partly in section of modified forms of my invention. In Fig. 15 a portion is broken out to reduce the length of the figure.

One of the disadvantages of the ordinary cigarette lies; in the proximity of the lightsmoked.

I ed end to the face and eyes of the smoker.

To obviate this, cigarettes have been made with long mouthpieces permanently attached; or the cigarette has been inserted in a holder of some sort. In the first case the cigarette makes too long a. package to admit of wide adoption. In the second case, it is difficult to maintain the holder in a satisfactory sanitary condition. By my invention I provide a cigarette which requires a package only a trifle larger than is usual, and each cigarette is provided With its own mouthpiece which is;used but once and which removes the cigarette from close proximity to the face when it is being In a holder the cigarette is very apt to become loose and drop out or require adjusting to tighten the union, and moreover the appearance of a cigarette in a holder is usually very unattractive. By my invention the cigarette is held in perfectsecurity. The union between the body and the. mouthpiece is tight and the parts are in perfect 21111181116111 and proportioned to present an attractive appearance.

Broadly I accomplish the objects of my invention by providing a loose telescopic sleeve upon the body of the cigarette and means for rendering the joint between body and sleeve tight when the sleeve is extended. Means are provided for indicating or limiting the extension of the sleeve. Preferably means are also provided for limiting the amount of penetration of the body into the sleeve.

Since: the cigarette body is fragile, it will not admit of much handling to pull it from the sleeve. Therefore, the engagement of the sleeve upon the body is loose so that little or no effort is required in the first portion of the movement to extend the sleeve. When in extended position, however, the joint between sleeve and body is tight.

Referring first to Figs. 1, 2, 3, and 4, the body of the cigarette isformed in the usual way and may be either round or oval in section and of any desired length. The paper of the wrapper is that ordinarily used. For convenience I will refer to this body as cylindrical in form, althoit may be oval in section. The end 1 of the body 3 is enlarged by arranging thereon a bushing 2, Fig. 3, formed of a narrow strip of paper or other suitable material, so that the diameter of this inner end of the body is a small amount greater than that'of the opposite or outer end. The bushing 2 is secured to the wrapper of the body by paste or other appropriate means. Formed in the bushing by suitably applied pressure, before 1t is attached. is a. bead'4, which serves as a stop to limit the extension of the sleeve. The

same operation which forms the .bead curlsthe material of the bushing into cylindrical form so that in assembling a mere spot of paste is suflicient to. secure it to the body 3. The bead may be annular and continuous as shown. or its continuity may be interrupted, so that it is comprised of raised points or ridges. I shall'use the term head to mclude any raised portion whether continuous or not extending annularly about or partially about the bushing.

Enclosing the body of the cigarette is a. cylindrical sleeve 6 preferably formed of comparatively thick paper. The inside diameter of the sleeve is a very little larger than the diameter of the head 4 of the padded or bushed end of the cigarette body, so that the sleeve slides freely thereover. The inner end 7 of the sleeve 6 is contracted a small amount preferably by pressure in suitably formed dies, the diameter of the constricted opening being larger than the diameter of the body of the cigarette, but slightly smaller than the diameter of the bushing, so that upon the extension of the sleeve. the constricted end will be spread slightly upon being drawn over the end of the bushing, resiliently binding upon the bushing. Upon the engagement of the constricted end with the bead further extension is prevented. The sleeve 6 is thus in loose engagement with the body 3 in the position of the parts shown in Fig. 1, but when the sleeve is extended from the body, preparas tory to smoking the cigarette, as shown in Fig. 4, the constricted end of the sleeve firmly engages the enlarged end of the body and forms a tight joint therebetween.

After the body has been assembled in the sleeve, a resiliently rolled and folded piece 8 of light card is inserted in the mouth end 9 to prevent collapse. The resilience of the folded card is sufiicient to'keep it in place, but preferably a spot of paste is applied on the reenforcing member before it is pushed into place. The reenforcing member also acts as a stop to limit the penetration of the body into the sleeve. If desired, a waterproofing band may be applied about the mouth end of the sleeve, or the month end may be dipped in melted parafline or other suitable material which moisture-proofs the tip and at the same time secures the reenforcing member 8 in place, or it-so stiffens' the material, that the additional reenforcemcnt may be dispensed with. Also by making the sleeve of sufficiently heavy material, or by reenforcing it by an extra layer at the mouth end, the member 8 may be omitted. If desired, the mouth end may be crimpe'd as explained in connection with Fig. 15. In this case the inward projection of they crimped material furnishes a stop which limits the penetration of the body into the sleeve.

When packed the cigarette body is preferably nearly enclosed by the sleeve 6 as shown in Fig. 1, leaving the end 11 exposed a short distance. The sleeve is extended preparatory to smoking the cigarette by pulling the body out of the sleeve until the small end of the sleeve binds on the enlarged end of the body as shown. in Fig. 4. The

bushing may be a color such as gilt'or silver different from that of the sleeve and the body, so as to supply a visible means for determiningwhen the body has been. pulled out of the sleeve sufliciently, in addition to the indication given by the binding of the parts. Of course the bead and its function may be omitted, the constricted end of the sleeve merely binding upon the enlarged end of the body, and no positive stop being provided; or the proportion and form of the parts may be such that the bushing itself forms a stop to limit the withdrawal of the sleeve and to form a tight fit therewith.

Both of these structures are illustrated and explained herein.

In Fig. 5 I have shown an embodiment of my invention in which the enlargement of the body and the constricted opening of the sleeve is accomplished by a thin film of a suitable composition placed respectively on each. The composition band or pad 12 enlarges the body 3, and the pad 13 constricts the end of the sleeve. The composition may conveniently be one which dries quickly by the evaporation of a volatile vehicle, or one which hardens quickly in ordinary temperatures. and is applied by dipping. spraying or other suitable method. Both sleeve and body are cylindrical and each is of uniform size thruout its length. The sleeve is loose upon the body and the pads 12 and 13 are of such thickness as to cause them to bind upon each other when the sleeve is extended. The month end 9 of the sleeve is preferably re-enforced with a resiliently coiled narrow strip of card 14. A similar coil 16 is preferably though not necessarily inserted in the end 1 of the bodv of the cigarette. taking the place of the tobacco in supporting the wrapper at that point. The coil extends inwardly a short distance beyond the edge of the pad 12. and besides keeping the wrapper extended acts as a retainer for the tobacco. For the pads I may use a composition comprising wax or parafiine either alone or as a vehicle in which magnesium oxide or similar filler is mixed, or I may use a silicate,'preferably silicate of magnesia, in solution. If

desired coloring matter may be added. Preferably the pads are applied by dipping which normally results in a thin film of the material on both the inside and outside as clearly shown on the sleeve, Fig. 5. On the body the inside film helps to secure the coil 16 in place.

In Fig. 7 appears a cylindrical body in which is incorporated a short tube or ring 17 lying within the wrapper of the body. This ring firmly supports the wrapper, and the outside of the body at this point is the same size as the rest of the body, differing only in that it is hard and will not compress whereas the rest of the body is relatively soft. The sleeve 6 is constricted or tapered at one end 7 to form a light contact withthe body 3 sufficient to compress it slightly. but not enough to prevent the sleeve from bein easily extended on the body, the body flowing under the edge.

\Vhen the constricted end of the sleeve leaves thecompressible portion of thevbody and is drawn upon the unyielding portion over the re-enforcing ring, the parts form a tight tit. The month end may be crimped as shown in Fig. 15 or the folds 18 may be closely spaced and quite shallow as shown.

In Fig. 8, I have shown a modification of my invention in which the bushing is a band or strip encircling the end of the body with one or more turns, but preferably a plain bushing similar to that shown in Fig. 3, without. the bead. Enclosing the body of the cigarette is a. sleeve 6 which may be tapered the entire length as shown, or may be cylindrical and tapered on its inner'end (left. of the figure) for a portion only of its length as shown in Fig. 15. The inner end of the sleeve is of a size to permit easy sliding over the cigarette body but smaller than the diameter of the bushing, and when the sleeve is extended. the small end engages the bushing, which forms a stop and at the same time snugly engages in the tapered sleeve-end to make a tight fit between the parts. When first made the sleeve is evenly tapered thruout its length, the large end being formed according to the dotted lines 23. After the sleeve has been assembled on the body, the large end is preferably crimped on that of 1. It will be obvious without specific illustration that with a sleeve tapered its whole length, a tapered body could be substituted for the padded cylindrical one;

the large end of the tapered body functioning the same as the padded end of the cylindrical one, both as to forming a snug engagement and a stop to limit withdrawal.

Fig. 10 shows a c1ga-rette in which the edge of the wrapper of the body 3 is folded back upon itself to form a hem 27 which pads or enlarges the end of the body. The sleeve6 is similarly formed' with a hem 28 which results in a slight contraction of the opening. In both body and sleeve the hem, which'may be a single or double fold, is formed preferably on the outside as shown, or both on the inside, so that neither hem can form a shoulder for the other to abut against.

"In Fig. 11 I have shown the wrapper of the body 3 provided with a fold 29 divided by slits 31 along the edge, so that the flaps so formed will not lie too close to the body. A similar slit fold 32 is formed on the inside of the sleeve 6, the ends of the flaps lying apart from the wall of the sleeve. hen the sleeve is withdrawn from the body, these flaps or folds mutually engage under each other and give a tight joint between the two members.

Fig. 12 shows a construction in which advantage is taken of the resilience of the cigarette body. The body is cylindrical in form and thrnoutits'length is the same diameter. The end 7 of the sleeve is constricted as explained in connection with Fig. 7 sufficiently to slightly compress the cigarette body under the edge of the sleeve. A line 33 is preferably placed upon the body to mark the limit of extension of the sleeve.

Altho the edge of the sleeve presses into the body. the latter can be extended owing to its resilience, which permits it to .flow under the edge without injury. Instead of the line 33, I may use a folded or coiled thin strip or thread 34 attached to adjacent ends of sleeve and body to limit the extension of .he sleeve upon the body.

Fig. 13 shows a modified form of my invention in whicha double extension is secured by means of two sleeves, an intermediate sleeve 35 being interposed between the body 3 and the sleeve 6. It being obvious without specific illustration that any of the structures explained herein may be incorporated in the double sleeve construction.

Fig. 14 shows a cylindrical body and sleeve. The end 1 of the body is provided with a compound bead formed in the material of the wrapper by pressure in suitable molds or dies. This bead comprises the annular bead 36 raised avery little bit above the surface of the body and the short ridges or points 37 which project a very small amount above the bead 36. The compound head is adapted to be engaged by the annular bead 38 similarly formed on the inside of the inner end of the sleeve, first to form a snug engagement between the parts and then to limit the extension of the sleeve. Instead of the ridges 37 a continuous bead may be formed, but the ridges or points require less stretching of the paper. It is obvious that the constricted end of the sleeve may be formed if desired as shown in Fig. 2. A cigarette comprising a body, an ex- 1, just as it is obvious that the bead 4 of that figure may be formed of ridges instead of continuously.

Fig. 15' shows a construction in which both sleeve and body are cylindrical in form. The end 7 of the sleeve is tapered to form a constricted end the edge-being barely in contact with the cigarette body. The end 1 of the body is enlarged by inserting therein a resiliently coiled strip 39 of card heavy enough to slightly distend the wrapper of the body. Like the coil 16, Fig. 5, the coil 39 also acts as a retainer for the tobacco}.

The sleeve is extendedreadily from the body but binds upon the end enlarged by the coil 39. The month end is crimped on opposite sides, by the formation of inwardly projecting folds 40. Pressure of the lips of the smoker partially collapses the mouth end,

but it is prevented fromclosing by the resilience of the folds.

It is obvious without detailed illustration that other modifications may be devised by making other combinations of the features of construction explained.
