MECHANISM FOR PROVIDlNG ONE END 0F OF NEW YORK, N. Y.

SPECIFICATION forming part of Letters Patent No. 596,564, dated January 4, 1898.

Application filed April 1 5, 1897.

each comprising a tobacco filler inclosed in a paper wrapper and having one end of the wrapper coated or covered with moisture-resisting orf waterproofing material to serve as a mouthpiece; and'the invention consists in an improvement in mechanism or devices for accomplishing this result. Heretofore it has been customary, in order to protect the end of the cigarette from the effects of the moisture of the mouth of the smoker, which quickly permeates the thin paper wrapper and soaks into the filler, thus interfering with the smoking and flavor of thecigarette, to provide short mouthpieces made in separate pieces and slipped over theends of the cigarettes. These mouthpieces are generally made by forming paper blanks into funnel shape and coating them with melted paraffin or similar material, and although they are efiz'eetive for the purposeint'ended they add materially to the expense of the cigarettes. It has also been the practice to some extent when the cigarettes are made by the individual proccssthat is,.b v Wrapping short tobacco fillers of the length of the completedcigarettes in short paper blanks of substantiallythe same length. as the fillersto apply by any suitable means a coating of melted pa'raffin or other moisture-resisting material to one, end of the wrapper-blank and after the coating has dried or hardened to apply such wrap- I per to the filler to form the completed cigarette. A cigarette made in this way will be provided with a substitute for a mouthpiece which is integral with the cigarette and will protect to a large extent the mouth end of the cigarette from moisture as it is smoked.

\Vhen cigarettes are made individually, as before described, it is easy to apply the de- Serial No. 632,198. (NomocleLl sired coating to one end of each wrapperblank before such blank is wrapped around the tiller and thus produce the desired result;

but when the cigarettes are made by the continuous process--that is, by wrapping and securing a long or continuous strip of-paper around a long or continuous filler or rod of tobacco and then severing the; long cigarette thus produced into short marketable lengtl1s it hasbeen considered impracticable, althoughvery desirable, to provide that each severed cigarette shall have one end of its wrapper suitably coated to protect it from moisture. This result is especially important in view of the fact that a large volume of ciga-. rettfes are made by the continuous process and {that their wrapper endscannot-bethus coated after the cigarettes have been severed from the long cigarette without considerable expense. and the liability that the coating material will be brought in contact with the filler of the cigarette.

It is the object of my invention to accomplish this resultin an efiicient and economical manner by forming a long or continuous cigarette comprising a long or continuous filler or rod of tobacco inclosed in a longpaper wrapper and providing such cigarette with Figure l is a view of a long cigarette provided'with rings or sections of coating material. Fig. 2 is a section of a wrapper-strip .provided with sections of coating material.

Fig. 3 is a short or marketable cigarette having one of its ends provided with a ring or section of coating material. Fig. 4 is a side elevation of a machine for making cigarettes by the continuous process and a mechanism for applying coating material in sections to a long wrapper-strip and mechanism for cooling the same. Fig. 5 is an end view of mcch tions f coated material of greaterwidth and greater distance apart than those of Fig. 2,

and Fig. 8is a view of. a long cigarette provided with rings or sections of coating materialof greater-width and at greater distances apart than the cigarette shown in Fig. 1.

Referring to the drawings as illustratin my method, A' of Fig. 1 represents a long ci arette provided with sections or rings B of coating material, which extend around the exterior of the cigarette. These rings are formed by applying to the paper wrapper a thin layer or coating of any suitable material which willreadily dry. or hardenand will prevent the moisture of the mouth of the smoker from penetrating through the thin paper ofthe wrapper. Melted paraffin, stearin,-or any other material not injurious or disagreeable to the smoker and which can'be easily applied and will quickly dry orharden to form a thin even coating upon the wrapper-strip may be employed. v

. The width of the sections-orrings B when they are arranged as shown in Figs. 1 and 2 is preferablyabout one-half of an inch, and

the distance between them, including the width of one of the sections or rings, is equal to the length .of the mechantable cigarettes to be produced. Instead of arranging or disposing the sections or rings B as shown in Figs. 1 and 2 they maybe arranged as. shown in Figs. 7aud 8, where they are about one inch in width and theirdistances apart, including the width of one of the sections, is double that of the length of the short or merchantable cigarettes. When the long 'cigarette is formed and provided with rings of coating material, as shown in Fig. 1, it is divided into short or marketable cigarettes by cut ting or severing it along or near'the'line of union of the rings 13 with the, uncoated portions' of the cigarette, so that each severed cigarette will have one end of its wrapper protected by the coating material. In case the rings B aredisposed. as shown in Fig. 8 the long cigarette is divided or severed along the lines as as, which pass through the rings B and also midway between the rings 13, as along the lines 1 y, as indicated in Fig. 8, thus effecting that the contiguous ends of two short cigarettes are provided with a coated section or ring. The division of the long cigarettes into short or marketable lengths may be accomplished by any cutting devices adapted .for this purpose.

Referring now to the drawings asillustrat- 1 ing a preferred form, of mechanism embody ing my invention, Fig. 4 shows a machine, as X, for making a long or continuous cigarette by wrapping and securing a long strip. of p'aper around a long filler or rod of tobacco, and

rings of coating material with the body or uncoated portion of the cigarette, these mechani'sms being so arranged in relation to each other that they will operate together to pro-' duce the desired results. g

The main operative parts of the cigarette- -machine X, as shown in the drawings, are

suitably'mounted ona frame 0, and consist of filler-forming devices D, devices E for wrapping the paper strip around the fillerrod, devices for advancing the paper'strip and filler-rod, as belt F, devices, as G, for

securing the wrapper-strip around the fillerrod, and devices,'as H, for dividing or severing the long or continuous cigarette intoshort or marketable lengths.

Itis not considered .necessary to describe in detail the special construction and operation of the parts and devices above referred to, as they may be in all essential particulars substantially the same as those described .in

United States Letters Patent No.- 247,795,

dated October 4, 1881, to which reference is here made, or they may be of other and different construction, provided they operate to deliver a long or continuous filler or rod of tions at desired distances from each other.

anda device for cooling such material after it has been applied and before the strip isv brought in contact with the filler-rod are shown in Figs. 4,5, and'6 of the drawings, in which 1 is a frame conveniently secured to the base of frame 0 of the cigarette-machine X, in which are-rotatively journaled

rollers

2, 3, and 4, the latter being arranged so that its periphery will rotate in a reservoir or receptacle 5, which contains the coating material to be applied to form the sections B upon the wrapper-strip A. The

rollers

2, 3, and 4 arepreferably driven by suitable connection with the main shaft J of the cigarettemachine, as by beveled gears K and 6, the latter being fixed to the upper end of vertical shaft 7,-whoseopposite end carries gear 8,1

. of roller 2," which roller is preferably loosely Roller 3 is driven by mounted on its shaft. gear-wheel 11 on shaft 10 meshing with gearwheel '12 on shaft of roller 3, and roller 4 is driven by gear-wheel 1'2 meshing with gearwheel 13 on shaft of roller 4. The length of

rollers

2, 3', and 4 is preferably equal to or a little greater than the width of the paper strip A, and the roller 3' is provided with one or more ribs 14, extending along the length of its peripheral surface and parallel with its axis, and this roller is arranged relatively'to the

rollers

2 and 4 so that as the roller 3 ro tates the ribs 14 will come into contact with the surfaces of the

roller

2 and 4. The reservoir 5 may be of any aterial and shape adapted to receive and hold the coating material in proper relation'to roller 4 and is preferably made "vertically adjustable by' any suitable devices, as by screw-bolts 15, extending through brackets 16 and taking against the flan es 17, formed on the side of the reservoir. A scraper or doctor 18 for the purpose of removing any excess of coating material from the surface of roller 4 is conveniently secured to the edge of the reservoir 5 and made adjustable to the surface of the roller by a set-screw, as 19.

The coating material-as paraflin, stearin,

or any other suitable substance adapted for the purpose indicatedmay.be melted in the reservoir 5 or kept in the desired state of fluidity by any suitably-applied heat, as by a jet or flame of lighted gas from a burner 20, located beneath the reservoir, and the

rollers

3 and 4 may be heated to maintain the coating material in a fluid or melted condition as it is conveyed from the reservoir to the paper strip by a current or currents of heated air applied to-the interiors of these rollers. A convenient construction and arrangement for this purpose is to make the

rollers

3 and 4 hollow or provide them with cavities and to form channels 21, leading through one end of their shafts and connected with the ends of

pipes

22 and 23, which lead from a Bunsen burner 24 orgother device for heating the air. The rollers may be of any suitable material as rubber, brass, or other metal which'will 1 take the melted material from the reservoir 5 and properly convey and apply it to the pa-' per strip as it is advanced between the

roll ers

2 and 3. i

The arrangement of the ribs 14 on the'roller.

3 is such that they will take the coating material from the surface of the roller 4 and apply it to the paper strip in sections B of the desired width and at equal distances apart, as shown in Figs. 1 and 2, the distance of the sections B from each other, including the width of one of the sections, being equal to the length of each of the cigarettes when-they are severed from the long cigarette.

The devices for advancing the paper strip.

I through the mechanism which applies .the

. coating material are arranged to operate in 6o properrelation to or in unison with-the devices which' advance the strip and filler through the wrapping devices and deliver the long cigarette to the cutting-ofi devices. In the construcilion shown in the drawings the device whic performs these functions is the. endless belt F, which passes through the wrapping devices and by its constant move ment drawsthe strip between the

rollers

2 and 3 at the same rate of speed at which it advances the strip and filler through the wrap ping devices and delivers the completed long cigarette to the cutting-off devices. The belt F is operated by passing over the pulley L, which is driven from the main shaft J through the beveled gear M, meshing with beveled gear N, the latter being fixed to the pulleyshaft. As the cutter-blade Q is arranged to come into contact with the long cigarette and sever therefrom asingle short cigarette at each complete rotation of the main shaft J, the gear M should be so related to the gearwheel Non the pulley-shaft that at each rotation of the shaft J the desired length for each short cigarette will be advanced past the cutter-bladeO, while the paper strip will per strip as often as a cigarette is presented to the cutter to be severed. It is necessary to so adjust the cutter-blade O that it will sever the long cigarette at or close to the line of union of the sections or rings B with the body or uncoated part of the cigarette, the severing cut being preferably along the lines a: w, as seen in Fig. 1. It is desirable that the out should be through the uncoated portion of the cigarette, but as near as practicable to the coated sections or rings, so that, on theone hand, little or none of the coating material will be on the lighting end of the cigarette and, on the other hand, only a small section or line of the uncoated wrapper will be on the extreme mouth end thereof.

To obviate the liability of the lighting ends of the cigarettes carrying any of the coating material, a different disposition or arrangement of the sections or rings B is easily made.

Instead of applying the sections at a distance apart substantially equal to the length of the.

desired cigarette, as shown in Fig. 2, they may be double such distance apart, as shown in Fig;. 7, and in this case they are preferably about double in Width, so that when the long cigarette is presented to the cutter-blade to be severed it will be in the condition shown in Fig. 8 and the cutter will be adjusted or set to cut along the lines we: and 'y y, as shown in Fig. 8. In this case a single cut will form the mouth ends of two cigarettes,

while the next cut will form the lighting ends of two cigarettes, or vice versa. The only change required in the mechanism to accomplish this result is to increase the width of the ribs 14 on roller. 3 and arrange them at front of the blast and the strip will be so held' double circumferential distance from each other.

To facilitate the hardening or drying of the coating material after it has been applied to the wrapper-strip, so that it will not adhere to orsoil the b,elt F or other parts of the cigarette-machine, a blast or current of air may be directed upon the strip at any convenient point of. its advance. A mechanism foreffecting this result is designated by Z in Fig. 4 and is located to deliver a blast of air against the strip as it passes over a pulley 25, the length of the pulley being preferably equal to or greater than the width of the strip. The coated sections 13 as the strip passes over the pulley will be brought directly in in position at this point that -theblast will be uniformly delivered across its entire width. The mechanism Z may be of any construction adapted to create and deliver the desired blast of air upon the strip. As shown in the drawings, it consists of a rotating fan 26, mounted on shaft 27, which is driven from main shaft J of the cigarette-machine through

pulleys

28 and 29, connected by belt 30, and gears 31 and 32.

The expression long or continuous ciga-.

rette as herein used is applied to a cigarette whose length is equal to or greater than the combined lengths of several cigarettes as they are generally sold to consumers in the 7 market.

The operation of the mechanism hereinbefore described, and shown in the drawings, is briefly as follows: The long paper strip A is drawn, under proper tension, from a reel or other convenient supply, and is properly threaded through the mechanism, passing between the

rollers

2 and 3, over the pulley 25,.and through the wrapping devices E,above and in'contact with the endless belt F, by

which the strip'is continuously advanced.

As the strip passes between the

rollers

2 and 3 the sections B, of coated material, are applied at equal and desired distances apart by X the pressing contact of the ribs 14 of the roller 3, this pressure being resisted by the frictionally-driven roller 2, and the ribs taking the coating material from the surface of roller 4, which dipsinto thereservoir 5. The

, applied coating material is dried or cooled during the passage of the strip from the

rollers

2 and 3 to the point of its contact with the endless belt F, and this drying or cooling may be hastened, if desired, by the impact of a blast of air upon the strip as it passes in its course. When the strip reaches the wrapping devices, the filler-rod, formed by any suitable mechanism, is delivered upon the strip, which is wrapped around the rod, as the two are advanced through the wrap ping devices, the wrapper being secured in place by the devices G, thus forming a long or continuous cigarette provided with a series of sections or rings B of coating material extending around its exterior, as shown in Figs. 1 and 8. The long cigarette is then advanced to the cutting-off blade 0, which is set or arranged to operate in unison with the mechanism which applies the coating material to the strip to sever the long cigarette into short. or marketable lengths in the manner before described, so that each severed cigarette will carry upon one of its ends a section or ring of coated material to serve as a mouthpiece.

In the construction of the mechanismshown in the drawings the operations arepreferably continuous, the strip A being continuously advanced and supplied with sections of coating material, the filler-rod being continuousl y delivered upon the strip,and the strip being continuously and progressively wrapped around the filler-rod to form a long or continuous cigarette, the continuity of the operations being limited only by the length of the cigarette or filler-rod or the action of the machine.

It is not intended to limit this invention to any special form or construction of devices or mechanisms for applying the coating material or for forming and delivering the fillerrod to the wrapper-strip, or wrapping and securing the same around the rod, or for dividing the long cigarette thus formed into .short or marketable lengths, sincerit is evident that many forms of mechanisms or devices may be employed for these purposes without departing from the principle of the invention.

That is claimed as new is- 1. The combination substantially as set forth, in a mechanism for making cigarettes withmoisture-protected ends, of devices for applying a series ofsections of coating material to a long wrapper-strip, devices for delivering a long filler or rod of tobacco to the strip, devices for wrapping and securing the strip around the filler-rod to form a long cigarette with a series of surrounding rings of coating material, and devices for severing the long cigarette into short marketable cigarettes, whereby each severed cigarette isprovided with a ring of coating material at one of its ends.

2. The combination substantially as set forth, in a mechanism for making cigarettes with moisture-protected ends, of devices for applying a series of sections of coating material to a long wrapper-strip, devices for wrapping the strip around a long filler-rod, and means for cooling or drying the applied coating material located between the devices for applying the same and the wrapping devices.
