SPECIFICATION forming part of Letters Patent No. 355,968, dated January 11, 1887.

Application lell August 30, 1884. Serial No. 141,797. (No model.)

To all whom, it may concern:

13e it known that I, .TAMEs ALBERT BON- sA'cK, a citizen of the United States, residing at Bon'sncks, in the county of Roanoke and State of Virginia, have invented certain new and useful Improvements in Cigarette-Machines, of which the following is a specitieation, reference being had to the accompanying drawings.

In the drawings, Figure 1 is a plan View of my improved cigarette-machine. Fig. 2 is a central vertical section taken on the line y g/ of Fig. 1. Fig. 3 is a central vertical section taken on the line a; :t of Fig. 1. Fig. 4 is an end elevation`of the cutting mechanism for severing the continuous cigarette into convenient lengths. Fig. 5 is a vertical section on the line fu e of Fig. 8. Fig. 6 is a Vertical section on the line ww of Fig. 3. Fig. 7 is aperspective view of the paper-folder, showing a section of the tobacco-filler with its paper cover. Figs. S and 9 are detailviews. Fig.

410 is a vertical section through two adjacent links of endless chain' my. Fig. 11 is an enlarged view of that part of Fig. 1 seen to the left. Fig. 12 is an enlarged vertical section through two adjacent links of chain m. Fig. 13 is a side elevation of one of the links in chain m. Fig. 14E is a sectional View on the line X X of Fig. 13, showing two links of the chain m connected by pivots m. Figyl is an enlarged side elevation, partly in section, showing the tube-forming devices F and G, iiller-forming wheel w", endless chain belts m and a, with their supporting wheels YV NW W NV", and pasting wheel 107. Fig. 16 is a vertical sectionon the line caofFig. l5. Fig. 17 is a vertical section on the line b b of Fig. 15, and Fig. 18 is a perspective view of metal guide G for giving the paper its initial curve.

Similar letters refer to similar parts in all the several views.

My invention relates to that class of cigarettemachines in which the loose tobaccov is first evenly distributed and afterward formed into a continuous rod or filler for a cigarette, and subsequently enveloped in a paper cover, which is pasted and sealed, and the continuous cigarette finally severed by appropriate cutting mechanism into convenient length.

The object of my invention is to improve avoid the annoyanceincident to the unsealing of the cover during the passage ot' the cigarette through the machine, and to proyide for keeping the freshly-sealed cover under pressure while being constantly fed toward the cutting-off mechanism.

My invention consists in certain novel devices and combinations of parts, which I will now proceed to describe, and point out particularly in the claims at the end of this speciiication. Y

A represents the frame ofthe machine, made of wood or, preferably, of metal.

B represents the first feed-belt or endless apron, upon which the tobacco is spread for distribution, supported upon a table, T.

C is a roller,'provided with pins on its face, which receives thetobacco from the endless apron Band passes it underl the smooth roller C, which presses the tobacco well down between the pins of the roller C', which allow said roller to passit under the concave back D.

C2 is a stripping roller, which, having a faster motion than roller C', strips the tobacco from it and throws it upon the second endless apron, B, which apron is distended bet-ween rollers R R2, journaled in the reciprocating frame A, which has motion imparted to it by means of the vibrating arm R5 and pitman R4, which are actuated by a crank-pin on pulley, p2".

A hood or cover, D', is applied to the end of the reciprocating frame A, covering the brush b and preventing the tobacco brushed off of the belt from iiying out into the room, and the frame is guided and supported in its reciprocating movements by the sleeves b2 b2, embracing and sliding upon the rod b3, attached to the main frame.

It will be observed that the endless apron B has both a revolving and a sliding or reciprocating motion, which causes the tobacco to be more evenly spread upon the third endless apron, B, which passes around the pulley R3 and forward over the curved edge of a subjacent table, T', which gives support to the upper section of the apron, the travel of which IOO carries the tobacco to asecondset of distributing-rollers, O3 Ct, and strippingroller C5, provided with aconcave back, D2. Said distributing mechanism is the counterpart of the'tirst set of three rollers above described. The tobacco is removed from apron B by a revolving brush, b, placed. in close proximity thereto and under the concave back D. The stripping-roller C5 thro ws thetobacco, which is now fully prepared, into the hopper H, from which it falls into the filler-forming mechanism, consisting of four vertical pulleys, p10 p p" p1,

and two horizontal pulleys, p1 p15, each pair ofI pulleysbeing connected by an endless steel belt, so as to form a receptacle for pressing the filler into a continuous rod. Near one end of said steel belts is journaled a compressingwheel, VVT, which is vrotated by the friction of the belts forming the sides of the trough at a, which converge at that point and are curved to run parallel to the sides of the wheel by backing-strips hh. The tobacco, in passing between the three steel belts above mentioned and under wheel NV, is thereby compressed`i nto the form of a continuous red or iller, and continues to travel forward in the machine. As the filler emerges from between the pulleyspu p13 it is fed upon a continuous paper ribbon or wrapper for the cigarette.

So far my machine does not differ materially from that described in my prior patents, numbered, respectively, 238,640 and 247,795, and of the dates of March 8, 1881, and Oetober 4, 1881.

In my machine as described in the above patents the tobacco was fed from the fillerforming mechanism upon a continuous paper ribbon and drawn therewith through a forming-die, which further compressed the tobacco and enveloped it in the paper ribbon after exposing the edge of the paper tothe action of a pasting-wheel, which caused the edge of the paper to adhere to the body of the cigarette when pressed upon it.

In my present machine I do not use the forming die or tube, which necessitates the use of an auxiliary tape or belt for assisting the passage ot' the tobacco and paper wrapper through the tube, the paper ribbon used for covering the cigarettes being too delicate to makethe passage through a die unassisted.

Instead ofthe forming-die or folding-tube, as used in my old machines, I use the following devices:

F represents a semicircular piece of metal having two slots, e e, cut into it from either side-one from the rightvhand side or edge, the other from the left-hand side--so as to form two entrances for the continuous paper ribbon, as shown in Fig. 7. F F represent two arms, by which said piece F is supported in position in the machine.

NV W2 are wheels about which the chain belt m is distended, the wheels being constructed in the following manner:

The circular disks g g, constituting one of the wheels, are provided with recesses g f/ at equal intervals upon their peripheries suitable to receive the bearing-pivots of a chain or belt. Said disks are connected by a central hub, g2, and mounted upon a suitable shaft, g, in frame A, as shown in Figs. 3, 5, and 6. The wheels WV and WW are alike and are hung in a similar manner.

Sprocket or chain wheel NVZ is connected by beveled gears w3 w" with the main drivingshaft M.

m represents a chain belt distendedbetweeu wheels W and VV, as seen in Figs. 3 and 15. Each link of the chain m is provided with two inner and two outer lugs or ears, mT m3, and

corresponding recesses, m m1", as seen in Figs.

12, 13, and 14, which admits of the interlocking of theseveral links ofthe chain by the insertion of reds or pivots m6, as is clearly shown in section, Fig. 14:. The chain n is formed in substantially the same manner as chain m.

73 VW represent two similar wheels to V WV, but ofsmaller diameter' and connected by a chain belt, a. l

E represents a paste-reservoir of cylindrical form, in which a piston is gradually forced down by means of worm-wheel w10 and screw .wu on shaft S", which is provided with pulley P24, the latter receiving motion from a pulley, p, on the shaft of the wheel W.

.w7 is a pastingwheel mounted on a shaft, S2, running parallel to the main shaft M, and is provided with a pulley, p, which receives motion from p ulleyp421 en main shaft M through asuitable belt. The pastingwheel is made IOO adjustable by means of thumb-screw S3 at the bottoni of the reservoir E. r

ws is a small grooved wheel adapted to run in the Ushaped recess of endless chain m. w has a semicircular groove in its periphery equal in diameter to one-halfof the cigarette, and the wheel receives motion `from a cord or belt ruiming around a pulley on its shaft and the pulley p29 on the shaft of the wheel VZ.

Gis a slightly-concave metal guide to conduet the continuous paper ribbon from the point between pulleys pup, where it receives the compressed rod of tobacco which forms the fller,to the top of wheel YV into the groove of endless chain m.

Motion is communicated to the various parts of the machine from'the main shaft M by means of gear-wheels and chain belts, inthe usual well-known manner, as shown in the varions figures. Ihe endless traveling chain or belt m, which is distended about the wheels IV 'v 2, has the outward face ofthe band,or the respective links of the chain when such are used, grooved,the groove having vertical walls which lead to a concave or semicircular bottom. Into the groove of the band or chain as above formed the paper ribbon for the cover of the cigarette is drawn and conformed tothe groove therein, and upon the paper in the groove is fed the already-formed tobacco iiller, which passes under the wheel w, the paper passing between the side of said wheel 20" and the vertical walls of the grooved chain IIO IZO

, ette.

or band m. Immediately in front of said wheel is placed the paper-folder F, which sets down in the groove of the chain or band sufficiently deep to form with its concave surface and the bottom of the groove a perfectly circular chamber, one end of the folder` beingformed to fit close against the under peripheral surface of the* wheel w, and forming a line tangent thereto. rIhe folder is provided with two supporting-arms, F F', by which it is held entirely free from contact with the Vertical walls of the groove in the chain m,so as to permit the upturned edges of the ribbon to pass between the folder and the sides or walls of the groove until the paper is drawn under the folder through the slots e e'. It will be ohserved that these slots are made one on either side'of the folder, and that the edge of the paperlast drawn under will be caused to overlap the other, so that if the paste is applied at the point indicated by the position of the pasting-wheel wl in Figs. 7 and l5, the overlapping edge will adhere to the under lap, thus enveloping the tobacco-filler with a continuous paper cover or wrapper.

Directly above the advancing chain m is a second band or chain, n, revolving on -pulleys 73 V, the chain being similar to m,but hav ing a face sufliciently narrow to enter the groove in m.. rIhe two grooves in bands m and n are semicircular, and their parallel sides form a cylindrical tube or bore, which receives the cigarette and causes it to constantly advance bythe revolution of the bands or chains in and a. The cigarette being once drawn into this tube is compelled to advance with it until the withdrawal of the bands vas they diverge on their return travel, the cigarette being Vfed intok the guide or holder g", and projected against a revolving knife, k, which cuts it into the desired lengths.

The pasting device differs from that in my former patents herein referred to in the following particulars: In my former patents the paste-reservoir E rested upon a roller, the peripheral face of which was slightly concave, and the wheel which supplied the paste to the edge of the paper ribbon rotated on a vertical axis and at right angles to that of the roller upon which the reservoir E rested. As it was necessary that the wheel transferring the paste to the paper should have a narrow rim to avoid using an unnecessary quantity of paste, I found in practice that the paper in being drawn through the forming-die often varied sufficiently from a direct line to carry it below the edge of the pastingwheel, and consequently the paper received no paste in such places, and the cigarette would open immediately on leaving the tube. To overcome this difficulty in my present machine, I cause my pasting- 'wheel to receive its supply of paste directly from the reservoir, and I rotate the wheel at right angles to the line of travel of the cigar- By this means I remedy the difficulty named, the action of the wheel having a const ant tendency to keep the paper well up under it, and the cross movement givento it has a tendency to apply the paste more thoroughly and evenly. v

The cutting mechanism being substantially the same as that shown in my patent ofOctoloer 4, 1881, already referred to, will therefore need no further notice here.

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is-

l. In a machine for making a continuous cigarette, two endless traveling chains or belts, each having a peripheral groove, and the parallel faces of which are adapted to form by reason of their grooves the upper and lower halves of the cylindrical chamber, in combination with a semicircular paper-folder having side openings to accommodate the two edges of an endless paper ribbon, substantially as described.
