CONTINUOUS-CIGARETTE MACHINE.

fiPECIFICATION forming part of Letters Patent No. 543,839, dated August 6, 1895.

Application filed October 1'7, 1894. Serial No. 526,189. (N0 model.)

To aZZ'whom it may concern.-

Be it known that I, BERN HARD BARON, a citizen of the United States, residing in the city, county, and State of New York, have in- Vented certain new and useful Improvements in Continuous-Cigarette Machines, of which the following is a specification.

My invention relates to that class of machines in which a continuous rod is formed from loose material, and in the manufacture of cigarettes, fed toa traveling strip of paper and afterward inclosed thereby and sealed therein; and my invention consists in a mold for molding the tobacco-rod, or rod of other material, composed of endless traveling bands, and of means for holding the inturned edge of the paper in contact with the molded rod,

and of certain details of construction, as hereinafter fully set forth, and as illustrated in the accompanying drawings, in which- Figure 1 is a longitudinal sectional elevation of sufficient of a cigarette machine to illustrate myimprovement. Fig. 2 is an enlarged plan view of the molding devices shown in Fig. 1. Fig. 3 is an enlarged plan in part section of the wrapping devices shown in Fig. 1. Fig. at is a cross-sectional view on the line 4 4, Fig. 2. Fig. 5 is a cross-sectional view on the line 5 5, Fig. 2. Fig. 6 is a cross-section on the line 6 6, Fig. 3. Fig. 7 is a perspective view of Figs. 8 and 9 illustrate modified ,forms of the lower mold-section.

In the ordinary modes of forming continuous fillers, or as they are termed filler-rods for cigarettes, it has been common, in many instances, to make use of devices which act upon a mass of tobacco to suddenly compress the same to about the size of the finished filler-rod. While these have proved to be more or less successful in different instances, it has been found that it is a serious disadvantage to suddenly compress the tobacco, and. in order to obviate this objection I make use of a filler-rod forming-mold consisting of several parts traveling in unison, which are gradually brought together until they form a practically-closed chamber, the convergence being so gradual as to prevent any inj uriouslyabrupt pressure upon the tobacco; and I further form the parts of the mold of elastic material, which acts less injuriously upon the tobacco than molds made of metal or rigid material, and which has the further advantage of being in endless pieces, capable of being carried around supporting guide-wheels, so that they can travel continuously with the tobacco or rod and can be moved toward or from each other with facility.

The mold may consist of any suitable number of endless traveling sections or bands; but I prefer to make it of three bands 01, b c, the band a, which is generally the lower section of the mold, having a groove x with converging sides which tend to throw the tobacco,

which is deposited sometimes upon the said band, but preferably on the paper strip thereon, toward the center, and which also serves as a guide upon which the other two bands I) 0 may move downward toward the center of the groove to gradually compress the mass therein.

Each of the bands or sections 0 Z) is so constructed in cross-section that when the two bands are brought together in their lowest position in respect to the band a there will be formed or inclosed a substantially cylindrical opening or chamber formed by the central rounded portion of the groove so and by the rounded portions or grooves 71 i at the lower edges of the bandsor sections 0 b, which may otherwise, however, be of any suitable crosssectional shape.

Each of the bands or sections a b 0 may be of any desired length. Preferably they consist each of a continuous rubber band, the section a passing around two guide-wheels 5 6 and over the table or platform 7 of the machine, and the sections 1) 0 being each carried by two guide-wheels 8 9, which are so arranged that each of the sections 0 b is supported at an angle to the section a. Inasmuch, however, as the pulleys 8 9 do not alone support the bands I) c in the proper position for opera tion, I make use in connection with them of guides 10 11, which will support a portion of the sections 1) c in their proper positions at the point where it is necessary for them to 0pcrate directly upon the tobacco. Each of these guides 10 11 is so constructed as to coincide at its inner face with the outer face of the band or section which is in contact with it and to support the section at the point where it co-operates directly with the section a in such wise as to cause the said section b or c to gradually approach the center of the section a and also gradually descend until it meets the other side section and forms and closes the traveling chamber or mold in which the tobacco-filler rod is formed. Thus the lower section a is supported upon the table 7 and each of the sections 1) c is supported against its guide, and the sections all converge until they are in contact and form a closed traveling chamber, and it therefore follows that the tobacco deposited upon the lower section and naturally gravitating toward the bottom of the groove in the said section will gradually be collected in a mass approximating a tobacco rod in the center of the lower section and will be gradually compressed and condensed until the rod is formed, and will then be carried with the closed traveling chamber and held in a compressed state for a distance equal to the distance in which the sections constituting the traveling mold are in close proximity to each other.

After the tobacco has been held in a condensed state for a proper length of time the rod is released, and this is effected by gradually carrying the side sections 1) c outward and upward until they leave the section a, which results from the form of the guides and the arrangement of the wheels 9 in respect to the guides, or the latter may be continued for any desired length, so as to conduct and guide and direct the sections Z) c away from the section a.

To compress and hold the sections together at the point where the tobacco is subjected to the greatest pressure, I may use a pressure device in the form of a pressure-wheel 13, so arranged as to bear upon both of the sections Z) 2: about the point where they are in contact with each other and hold them in such contact while traveling togetherand prevent anyp0ssibility of their spreading or opening.

To further facilitate the above-described operations, it may be better to subject the tobacco after it has been deposited upon the section a and before it is acted on by the side sections 1) c to a certain amount of pressure, and this can be done by means of a presserwheel 15, having a grooved edge and arranged vertically above the section a in position to compress the tobacco toward the center and deepest portion of the groove of said section. If desired, the

wheels

13 and 15 may be supported by spring-bearings, with springs 30 exerting a pressure tending to depress these wheels.

The parts above described will of themsurface of the said strip and carry the strip and the tobacco together through the traveling sectional mold, compressing the tobacco directly upon the strip. Thus the strip of paper is conducted from its propersupporting-roll upward toward and into the traveling section a at its receiving end, and the tobacco is deposited from any suitable feeding device upon the strip of paper, and is then conducted with the strip through the traveling sectional mold and is compressed upon the paper, (the paper being bent to conform to the shape of the groove in the section 01,) until finally the paper with the rod upon it leaves the sections 1) c. It then becomes necessary to turn down one edge of the paper over the rod th us molded, andthis is done bybringing one edge of the paper into contact with the inclined or diagonal edge u of a bar or folder, which is supported above the section a at one side of the same and extending into the groove .23, after which the opposite edge of the paper is brought against an inclined or diagonal edge to at the end of a strip or bar 19, Fig. 3, which also extends into the groove of the section a at the opposite side of said groove, this edge of the paper, however, being thereby brought only to a vertical position, so that its inner face may be presented to the action ofa pastew wheel 20, which applies the paste to the inner standing face of the paper in a manner too well known to need further description. After the paste has thus been applied the standing edge of the paper is brought against the inclined edge 21ofa folder G, which lays thepasted edge of the paper over and upon the other inturncd edge and holds it upon the same until the two edges are pasted together around the inclosed tobacco rod.

I-Ieretofore much difliculty has been experienced in cigarette-machines in holding the tobacco rod in its compressed state at the point where one edge of the paper is turned down upon the rod, while the other is held standing to approach the pasting device in proper position. This has resulted from the fact that any attempt to bear upon the tobacco rod at this point throughout its whole length would be attended with a great deal of friction. In order to overcome these objectionsI make use of another traveling moldsection 6, in the form of a traveling band having a face rt, corresponding with that of a section of the tobacco rod and its wrapper, at the point where it bears upon the same, and I impart to this band the same motion that the tobacco rod and its wrapper have, so that they travel together under compression in connection with the lower section a to a point adjacent to the paster-wheel.

The section e may be supported in any suitable manner. As shown, it is supported upon two wheels 23 24, and it preferably has a flange m, Fig. 6, for hearing against one edge of the section a, so as to properly define the position of the section e at all points and prevent too great pressure at any point or at per. The tobacco rod is thus held under proper compression during the entire time between the folding in of one edge of the wrapper-strip over the same and the point where the paste is applied.

While I have referred to the lower section a as a section of one piece, it will be evident that it may consist of two pieces, which together constitute a section having a central groove deepest at the center-as, for instance, as shown in Figs. 8 and 9.

It will be evident that when the paper is carried in contact with the traveling sections of a mold, which sections consist of rubber or other soft elastic material, that there is much less danger of wounding and tearing the same than could possibly result where the paper is drawn through 'a former of any kind by means of a strip or tape, and it will also be evident that as the paper does not come in contact with any standing or stationary part (except with the folders and where the back edge of the paper travels against the part that holds it vertical during the pasting operation) there is very little friction, and the speed of operation may be very greatly increased over that usually employed; but in order still further to increase this speed, if necessary, the back support of the paper, instead of being astationary strip, as before described, may be a roller arranged as shown in dotted lines 25, Fig. 3.

I have not shown in connection with the parts above described any devices for imparting movement to the various rollers and for driving the same positively, because it will be evident to any mechanic that ordinary driving-gears from a shaft or other suitable devices may be employed.

Any suitable means may be employed for depositing the tobacco on the traveling wrapper-strip. I have shown a conveyer-belt s, Fig. 1, and two grooved rollers 25 25, and an upper. guard-plate 26, the belt conveying the tobacco between the wheels, which collect it to the center of the belt, and the latter delivers it to the traveling wrapper.

Without limiting myself to the precise construction and arrangement of parts described, I claim as my invention 1.
