CIGARETTE-MACHINE.

SPECIFKCATION forming part of Letters Patent No. 522,895, dated July 10, 1894.

Application filed December 29, 1893. Serial No. 495,104- (NQ 11105913 To @ZZ whom it may concern,.-`

Be it known that I, FERDINAND J. HAGEN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Cigarette-lVIachines, of which the following is a specification, reference being had therein to the accompanying drawings.

In the drawings, Figure l designates a side elevation of a cigarette machine embodying my improvements; Fig. 2 a vertical section of the same, taken on the line 2 2 of Fig. 1; Fig. 2 a detail view of the regulating cams. Fig. 3 is a vertical sectional View of the tobacco-feedin g and disintegratin g mechanism, some of the parts being broken away for the purpose of better illustration; Fig. 4 a detail plan view of the swinging-frame carrying the chain rollers; Fig. 5 an end view of the machine. Fig. 6 is a detail view showing more clearly the arrangement of the pressure guidebars between the exit ends of the main feed- `This invention relates to that class of machines known as the continuous cigarette machines, and it has mainly for its object to provide improved mechanism for uniformly feeding the tobacco to the forming-belt, said feeding mechanism being entirely automatic in its action, as more fully hereinafter appears.

A further object of this invention is to so arrange the filler-forming belt that it may be readily removed and replaced without disturbing the other parts of the machine, whereby a material saving in time is effected, as more fully hereinafter appears.

I will now proceed to describe the preferred construction for carrying out my invention, but it is understood that this construction may be departed from without departing from the spirit of the invention.

Referring to the drawings by letters, A designates the main frame of the machine and A a smaller frame mounted upon the table ofthe main frame at one end thereof; A designates a frame or casing mounted on the main table between the sides of the frame A'.

A feed-belt a of the usual construction is suitably mounted adjacent to the casing A" and is adapted Vto convey the tobacco to the main feed-belts b, which are mounted upon rollers b and are constructed of curved metallic links transversely pivoted togethenand extending entirely across the face of the rollers.

As stated, the links are curved transversely, so as to fit the curved faces of the rollers, and

the rollers are provided with longitudinal grooves b in their faces for the reception of the transverse hinges of the links.

The two rollers carrying the upper chain are mounted in a frame consisting of two parallel side-bars c c, the shaft c of the front roller being rigidly fixed in said arms and the roller being loosely mounted on said shaft, while' the rear roller is fixed on its shaft c and said lshaft is journaled loosely in longitudinal slots in the ends of the arms c.

The ends of shaft c are extended outwardly beyond the arm c and journaled loosely in boxes c3, which are free to work in vertical slots formed in the frame A', thereby permitting said shaft c and its rollerito vibrate vertically a limited distance; the boxes c3 are normally heldl down in the lower ends of their slots by means of coil-springs c4 held in place by caps c5. The ends of shaft c are also extended and journaled 'in the sides of the frame A', thereby forming the fulcrum or oscillating point of the side bars or levers c.

The rollers of the lower chain or belt b are mounted rigidly on their shafts and the shafts are extended and journaled in the frame A', and the upper belt or chain is driven in unison with the lower belt by means of a gear d secured on one end of the rear lower shaft and meshing with a similar gear on the vibratable shaft c, the 'teeth of these gears being sufficiently long to enable the upper gear to move vertically'a short distance without beA coming disengaged from the lower gear.

The shaft of wheel d is driven by means of a large spur gear d2 secured on its opposite end outside of casing A', and this gear d2 is driven by a pinion d3 secured on a short shaft d4, whose inner end is journaled in the casing A and whose outer end is journaled iu a bearing d5 mounted on the upper end of a vertical shaft'd, hereinafter described.

Between the exit or rear ends of the chain belts are located a pair of pressure guide bars e e', the former being carried by the levers or ICO frame-bars c, thereby being vertically vibratable, and the latter being secured at its ends rigidly to the frame A. These two bars are formed exactly alike in cross-section, their adjacent faces being fiat and directly in line with the adjacent faces of the belts, and their faces next to the belts being transversely curved or concaved correspondingly to the curvature of the rollers b and fitting nicely against the belts as they pass around the rollers, the edges of the bars formed by the junction of these two faces being sufficiently sharp to scrape or remove the tobacco from the chains and direct it between the two bars. The rear edges or faces of the bars are concaved to correspond to the curvature of a roller or shaft e2 journaled in the frame a', directly to the rear of said bars, and driven by means of a belt e3, connecting a pulley e4, secured on one of its ends, to a larger pulley c5 secured on the end of the main shaft e6 journaled in the main table.

The shaft or roller e2 is provided in its surface with a series of short pins or spikes, which pass close to the curved faces of bars ce and receive the tobacco and deposit it in a chute or funnel f supported between the side frames A.

The funnel f deposits the tobacco between a pair of rolls f f2, the former of which is journaled stationarily in the frame A and is provided with a smooth surface, and the other roll f 2 is journaled in the lower ends of swinging links f3 pivoted on the casing A. The roller f2 is kept resiliently pressed toward the roller f by means of springs f4 bearing against the lower end of links f3 and adjustably supported in sockets f5, mounted on a/suitable part of the frame, by means of set screws f6, these screws serving to vary the pressure exerted by the springs.

Supported between rolls ff2 is a scraperbarg, which is substantially triangular in shape and has its uppersharpened edge bearing upon the surface of the smooth roll f to scrape the tobacco therefrom, While the face adjacent to the roll f2 is concaved to correspend with that roll. The lower side of the bar g is concaved to correspond with the cu rvature of a spiked-roller g', mounted in the frame A and driven by a belt g passing over a pulley g3 on the shaft of roller g and over the pulley c5 on the main shaft.

The roll f is driven by a vertical shaft h carrying a beveled gear h on its upper end which meshes with a similar 'gear h2 on the shaft of said rollf, said shaft hzbeing driven by means of a beveled gear h3 secured on its lower end and meshing with a similar gear h4 on the main shaft.

The roll]c2 is driven at aspeed corresponding to the roll f by means of small gears 71.5 h, secured on the adjacent ends of the shafts of said rollers, the teeth of the gears being sufficiently long to allow the roll f2 to vibrate slightly without disengagement.

A funnelshaped casiug'iembraces the rolls f f2 and g and serves to convey the disintegrated tobacco into a trough j supported along the side edge of the lnain table. The endless filler-forming belt 7c travels in the trough j and serves to compress the tobacco into a continuous filler 7c. To accomplish this the trough 7' is formed with a U-shaped groove where it 'receives the tobacco from the chute t', as shown in Fig. 3, and from that point its side edges are gradually turned over to acircular shape, as shown in Fig. 2, whereby the edges of the belt are folded over upon the inclosed filler to compress it to the desired density or into'a rod of tobacco. The belt 7c is mounted upon pulleys k2 7c3 supported at the sides of the main vframe A, out of thc way of the other mechanism, the larger roller 7c3 being driven by a beveled gear Z194 secured on the inner end of its shaft and meshing with the beveled pinion h4 on the main shaft.

Upon the frame A, at a point between the pulleys k2 k3, is mounted a belt-tightener, which consists of a vertical arm Z pivoted at its lower end on the frame and carrying a roller Z at its upper end, adapted to support the slack of the belt and keep it taut, said arm being readily adjustable upon a suitable slotted segment Z2 by means of a lever nut Z3.

It will be observed that by lowering the belt-tightening arm the belt may be readily slipped off its pulley `and out of the trough, and as readily replaced Aby a new belt. This capability of readily replacing the formingbelt is an essential feature as it saves valuable time consumed in changing the belt in the machines now in use. y

As the filler Zo leaves the forming belt it passes onto the paper m, which is unwound in the usual manner from arollm and passed through a suitable folding and pasting device m2, by which it is folded and pasted around the filler.

Asuitable presser wheel m3 may be mounted at the inlet end of the folder to compress thc filler previously to being wrapped in the paper. The paper is carried through the former or folder by means of the usual belt n which Y is kept taut by means of a tightener n. Below the large pulley 71,2, carrying belt n, is a frame n3 pivoted at one end and vertically adjustable at its other end, by means of a cam n4, and carrying a series of rollers a5 adapted to bear upon the surface of the belt as it passes over pulley n2 and thereby serve to smooth the wrinkles out of the belt and prevent the same slipping. The means for pasting and folding the paper around the filler are not claimed in this application.

The means for automatically regulating the feed is constructed as followsz-Adjustably connected to the extended end of one of the levers c is a vertical rod o which is pivotally connected at its lower end to a vertical slide o working in vertical ways o" supported on the main frame A. The slide carries two cams o3 which are similarly constructed and IOO connected together by a vertical pitman o4. The upper cam is connected by a rod o to a pivoted lever p which has one of its ends forked so as to embrace pins p carried by a non-rotating collar fitted in a groove in the hub of a friction wheelp?. The friction wheel p2 is connected to shaft d6 by means of a spline and feather, whereby it will be compelled to revolve with said shaft d6 but may be moved vertically thereon. The friction lwheel p2 bears against the face of a larger friction disk p3, carried by the short shaft dhereinbefore mentioned. The shaft d6 is driven by means of a beveled pinion p4 which meshes with a similar pinion p5 on the main shaft. As shown in Fig. l, a rollerq is journaled in the frame A and adapted to bear upon the inner face of the friction disk p3 and thereby prevent the thrust of the friction wheel p2 from displacingr said disk p3.

Journaled in hangersr, depending from the table of the main-frame is a short shaft r carrying a gear wheel r2, meshing with a pinion 'r3 on the main shaft d6. One end of the shaft r extends through a vertical slot s formed in the slide 0 and carries a friction wheel's' at a point between the two cams o3, the distance between the cams being slightly greater than the diameter of the said friction wheel s', as shown most clearly in Fig. 2.

The operation of the machine is as follows: The opposing chain-belts b receive the tobacco from the feed-belt a and convey it between the pressure bars e e', slightly7 compressing it during its passage between the belts. As will be seen, the adjacent faces of the bars e e must be formed substantially flat and must `always be exactly in line with the adjacent faces of the belts; should the upper bar not move exactly in unison with the upper belt and keep exactly in line with the working `face of the belt, the tobacco would either choke up between the belts or be pulled ont too rapidly from between the bars by the spiked wheel, as is evident. This peculiar arrangement of the bars is necessary in order that the feed be sensitive to the continually varying thickness of the tobacco. As the compressed body of tobacco is forced between the pressure guide bars e e', it is shredded and disintegrated by the rapidly-revolving spiked roller c2 and deposited in the funnel f, which in turn deposits it between the rollersf f2. The latter rollers, being rapidly revolved in unison and in opposite directions and being held resiliently together, again compress the tobacco and carry it downward; as the tobacco is carried downward it is scraped from the smooth roll by scraper-bar g and delivered to an opening t between the bar g and the casingz', and as it falls through this opening the spiked wheel g', revolving rapidly, further shreds or combs the tobacco before delivering it to the forming belt below. By means of this feeding and shredding mechanism the tobacco is deposited in the belt uniformly, whereby the filler will be of a uniform density throughout. As will be seen, the spring-pressed corrugated roller f2 compresses the tobacco against scraper-barg until it is taken olf by the spiked roller.

Should the bodyof tobacco passing between the pressure bars vary in thickness, the mechanism shown and described will instantly adjust itself so as to increase or decrease the speed of the chain-belts, according as the body of tobacco becomes thinner or thicker, and thereby compensate for the varying thicknesses and maintain at all times a uniform supply to the forming belt. As will be seen, to drive the chain-belts faster it is simply necessary that the friction wheel p2 be moved nearer to the center of disk p3 and to decrease the speed of the belts it is simply necessary to move said wheel p2 toward the periphery of the disk p3. As the body of tobacco diminishes the upper pressure bar e and the rear end of the frame carrying it will be depressed by springs c4 to conform to the thinner supply, and this action will raise the f rod o and bring the lower cam into contact with the slowly-revolving disk s. When the lower cam o3 comes in contact with the disk of the wheel s it will be turned in the direction of the arrow shown in Fig. 2, which will, through the medium of pitman o", turn the upper cam in the direction of the arrow shown and thereby raise rod o5 connected to the lever (p) controlling friction wheel p2; this action will raise the wheelp2 and move it nearer to the center of the disk p3 and thereby more rapidly drive the mechanism operating the chain-belts. When the thickness of the tobacco increases the operation will be the reverse of that just described-that is to say, the slide carrying the cams will be lowered sufticiently to rest the upper cam on friction wheel s', which will reverse the movement of this cam and draw down the friction wheel p2 toward the periphery of disk p3, thereby diminishing the speed of the feed-belts.

The only part of the periphery of each of the cams that comes into contact with the friction-wheelis the enlarged part (between t and t2), shown most clearly in Fig. 2a. The pitman is so connected to the cams that when the larger end t of the upper cani-surface is adjacent to the friction-wheel the smaller end t2 of the lower cam-surface is adjacent to the opposite edge of the friction-wheel, and vice versa. When the upper cam drops upon the frictionwheel it is carried around in the direction of the arrow and the speed of the chain-belts is gradually lowered; should the feed continue suiiiciently thick to keep said cam pressed against the friction wheel the cam will continue to turn until the smaller part p2of its surface is reached, at which point the turning of the cam and the downward movement of the slide carryngthe cam is arrested by the upper end of slot s coming into contact with shaft fr. This movement will bring the larger part t of the lower cam around into position, so that when the feed ICO IZO

becomes suiciently thin to raise the lower cam into contact with the friction-wheel, the operation will be the reverse of that'just described, the slot s serving also to limit the upward movement of the slide.
