METHOD OF PBODUCING MOUTHPIECES ON CIGARETTES.

Specification of Letters Patent.

Patented Jan. 2, 1912.

Application filed July 1, 1911. Serial No. 636,369.

To all uihom it may concern.-

Be it known that I, LEWIS I-I. SONDHEIM, a citizen of the United States, residing in the city of New York, borough of Manhattan, county and State of New York, have invented a new and Improved Method of Producing Mouthpieces on Cigarettes, of which the following is a full, clear, and exact description. I

The invention relates to mouth-pieces for cigarettes formed by treatin the tobacco filling at one end with a binding substance,

'so that the tobacco is'bound together or solidified to a degree to withstand the pressure of the teeth in the smoking of the cigarette.

In the present invention I proi ide for producing a series of indirect smoke passages through the mouth-piece, thereby avoiding the possible objection against direct and unobstructed passages that the smoke impinging on the tongue in concentrated jets may resultin more or less of a burning sensation. I furthermore by the present invention, maintain the bulk of the tobacco forming the body of the cigarettes against contamination by fumes or gaseous emissions from the binding substances employed, and thereby I preserve the normal flavor of the tobacco. By forming the mouth-piece with numerous indirect and minute passages, the mouth-piece is made essentially porous, whereby a large total surface is provided against which the smoke will impinge in its passage through the mouth-piece, and on which surface nicotin and the like will be deposited to a material degree.

Reference is to be-had to the accompanying drawings forming a part of this specification, in which similar characters of ref holder an air pressure device or pump is employed, a simple bulb 15 in the instance shown, which bulb communicates with the air chamber 11 through a tube 16 and inlet 17, whereby an air pressure may be produced in said'chamber. In connection with the holder and pressure device a receptacle as 18, is employed for receiving a binding substance, which may be of any suitable materials, preferably of the kind that become liquid or semi-liquid by heat and will solidify upon -cooling.

I preferably use as a binding material a composition formed'of shellac dissolved in stearin or stearic acid at or near the boiling point of the latter, or such othr combination of a resinous gum with a modifier of similar wax-like nature, as may produce an equivalent p'roduct.

Any suitable coloring matter may be employed, and to give capacity, finely powdered chalk, talcum, or the like, may be added.

In practice the cigarettes are dipped .in

r the binding substance as far as the outer coating of the mouth-piece is to extend, and the sald substance will rise on the lnslde a suilicient distance to form the solidified interior.

Concurrently with the dipping I prefer to maintain a slight pressurein the chamber 11 to prevent any gaseous matter from the binding substance rising into the body of the cigarette, but insuflicicnt to cause the air escaping at the dipped end to inordinately disturb the surface'of the fluid binding material.

Whether the mentioned slight pressure is produced or not during thedipping, a strong pressure of air is produced as soon as the end of the cigarette has been withdrawn from the impregnating material, causing an,

air current to pass through the cigarette from the clear end to the impregnated end, and sufficient to expel all gases arising from the material in the impregnated end, and to forcethe air through said end.

I do not confine myself to producing the current by pressure from the undipped end, and have shown another method of producing the air" current in Fig. 5, wherein suction is applied to the dipped end, causing an air current to pass through the cigarette from the clear end toward and through the dipped end with the same purpose and result.

In passing through the impregnated end the air currents will seek outlets around and among the particles of tobacco, producing numerous and indirect smoke passages 21 through the mouth-piece 20, so that when the binding substance has set to unchangeable form while under the influence of said air current, the mouth-piece will have been formed into an essentially porous and filterlike mass, which mass will be substantial, solidified and cohesive to withstand the process of smoking.

If the binding materials that I employ are not subjected to the air current while fluid, or semi-fluid, the whole mass will be come imperforate and essentially nonporous wlthout the necessary passages for drawing the smoke through the mouth-piece in smoking. By employing the air current, however, the necessar smoke passages are produced, while leavlng the mouth-piece firm, so that the wrapper, the tobacco filling, the binding substance within, and the coating on the exterior of the wrapper, are formed into a homogeneous mouthiece.

When the cigarette is densely pac ed with tobacco at the impregnated end, the described filling will maintain itself by its contact with the wrapper against ejection by an: moderate air current usedin forming the smoke passages. But when the cigarette is loosely filled, or in the event of it being desirable to useTa very strong air current, I prefer to use a screen plate 20 or other foraminous or reticulated support I upon which I place the dipped end of the cigarette before turning on the full air current, and which will retain the tobacco while allowing the air to pass through.

If the impregnating material leaves a bulge upon the end of the wrapper, I maintain the plate 22 (as shown in Fig. 2) at a temperature which will melt the bulge so formed, pressing the end of the mouth-piece .several times against said heated plate if required. The use of a heated plate, 22, also serves to prevent the mouth piece from sticking to the plate, as is liable to occur when a cold plate is employed.

trance of a scraping tool in cleaning the plate, or it may be, as in Fig. 4, a plate with perforations 25.

When employing the apparatus shown in Fig. 5, the cigarettes may be simply held in a block or holder 26 and dipped in the binding material held in a vessel such as 18, after which the cigarettes are immediately carried and pressed against the plate 27, having perforated seats 28 for the cigarettes, WhlC ing guides 29. Below the plate 27 and communicating with the perforations 28 therein, there is a chamber 30 from which the air may be partially exhausted by an exhaust fan 31, so as to produce a current of air downward through the cigarette in the direction of the mouth-piece 20, to withdraw all fumes and prevent their rising in the' cigarette, as previously explained. The chamber 30 may be provided with a drip plate 32 for any excess of binding substancethat may be carried by the mou piece and dropped therefrom, and such excess material may be withdrawn through a cock 33. I- prefer, however, to employ the method described 'in connection with Fig. 1, of maintaining a pressure during the application of'the binding material and coating, as

seats may advantageously have flarwell as subsequently to the dipping. The

step of removlng the fumes by a current of air is important in any case whether the smoke orifices are formed by said current or by other means, and whether. the binding substance, or a coating, is applied by dipping or otherwise. Therefore, with respect to my invention of producing an air cur-- rent through thecigarette from the end opposite the mouth-piece, I do not confine myself to the formation of smoke passages by means of the air current, nor to the main taining of pressure during the a plication of the coating, nor to the applicationof the coating by dipping, as the step of passing the air current through as stated is applicable to any cigarettes the mouthiece of which is formed by applying to't e cigarette or its wrapper a substance which would cigarettes, consisting in impregnating an end thereof with a binding substance, and producing'an air current therethrough.

2. The method of forming mouth-pieces on cigarettes, consisting of impregnating an end thereof with a binding substance while I maintaining an air current through the-cig' arette, from the opposite end toward the impregnated end.

3. A method of forming mouth-pieces on cigarettes, consisting in impregnating an end thereof with a binding substance, producing an air current through the cigarette from the opposite end, and opposing an obstruction to the free outlet of air at the impregnating end except at segregated points. 4, The method of treating cigarettes in the formation of ,mouth-pieces, consistingin applying at an end thereof a substance to form a coating, and passing a current of air through the cigarette from the opposite end to expel any fumes produced by said substance.

' 5. In the production of a mouth piece on.

a cigarette end, the herein-described process consisting in immersing the end of the ciga- I rette in a substance made fluid by heat and which sets when cold, withdrawing the immersed end from the said fluid, and subjecting the said end to heat after its withdrawal from the fluid and while maintaining an air current through the cigarette in a direct-ion toward the treated end.

6. A cigarette having a wrapper, waterproof at the mouth end, a filler, and a water proof binding material liquid when heated but solid at normal temperatures solidifying the filler at the said mouth end, and having air-blown passes or openings therethrough providing draft passages.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
