CIGARETTE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 707,766, dated August 26, 1902.

Application filed March 21, 1902. Serial No. 99,341. (No model.)

To (tZZ whom, it may concern:

Be it known that I, GUIDO FERRARI, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and St-ateof Pennsylvania, have invented certain new and useful Improvements in Cigarette-Machines, of which the followingis a specification.

Hy invention has relation to that class of cigarette-machine such as is shown and described in the United States Letters Patent No. 636,625, granted November 7, 1899,wherein paper is first cut in predetermined lengths, then a tube is formed from such paper by the machine, and the tube thereafter filled with tobacco and the ends of the tube closed or tucked in; and in such connection it relates to the general construction and arrangement of such a machine.

The principal objects of myiuvention are, first, to provide in a cigarette-machine mechanism simple in construction and efficient in operation for feeding a strip of paper forward for a predetermined distance, the strip being cut and the cut portion fed to a tube-forming mechanism; second, to provide in such a machine a simple and efficient tucking mechanism for tuckingin the ends of the paper tube; third, to provide in such a machine a simple and efficient mechanism for rotating the wheel or paper-tube holder and to stop the same, so as to present and hold the tube in proper position opposite the tobacco-filling mechanism; fourth, to provide in such a machine simple and eflicientmechanism for agitating, measuring, feeding, and compressing the tobacco prior to presenting the same to the paper tube; fifth, to provide in such a machine simple and efficient mech anism for stopping or cutting off the tobaccofeed; sixth, to provide in such a machine simple and efficient mechanism for regulating the degree of compression of the tobacco to be fed to the tube; seventh, to provide in such amachine simple and efficient mechanism for clamping or holding the paper tube in position during the filling of the tube with tobacco; eighth, to provide in such a ma chine simple and elficient mechanism tortilling the paper tube with the compressed tobacco; ninth, to provide in such a machine simple and efficient mechanism for clamping or holding the filled tube to prevent displacement of the same in the tube-holder at the return or withdrawing movement of the tubefilling mechanism; tenth, to provide in such a machine simple and efficient mechanism for moving the filled paper tube a certain distance and then holding the same in position during the tucking in of the other end of said tube; eleventh, to provide in such a machine simple and efficient mechanism for Withdrawing an empty tube when the tobacco-feed has been accidentally orotherwise cut off; twelfth, to provide in sucha machine simple and efficient mechanism forautomatically stopping the machine in case the paper is accidentally not fed to the tube-holder and tube-forming mechanism, and, thirteenth, to provide in such a machine simple and efficient mechanism for preventing backward or retrograde movement of the operating parts of the machine.

My invention, stated in general terms, consists of a cigarette-machine constructed and arranged in substantially the manner hereinafter described and claimed.

The nature and scope of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, in which Figure 1 is a top or plan view of a machine embodying main features of my invention, the tobacco-feeding mechanism being illus trated in section, so as to more clearly illustrate other portions of the machine. Fig. 2 is afront elevational view of the machine, illustrating also a portion of the paper-reel. Fig. 3 is a rear elevational view of the machine with the tobacco-feeding device shown in section and illustrating the mechanism for filling the paper tube with tobacco,tuckingin the open end, and ejecting the formed cigarette. Figs. 4 and 5 are crosssectional views, respectively, on thelines4 iand5 5 ofFig. llooking toward the left of the machine. Figs. 6, '7, and 8 are enlarged detail views illustrating, respectively, in longitudinal section, top plan view, and side elevation the mechanisms for feeding a strip of paper forward for a predetermined distance, for cutting the same, and for feeding the cut portion to a tube-forming mechanism and atube-holder. Fig. 9 is an enlarged cross-sectional view illustrating in detail the tobacco agitating, measuring, feeding, and compressing mechanisms. Fig. 10 is an enlarged detail View illustrating in front elevation the mechanism for compress ing the tobacco and regulating the degree of compression of the same. Fig. 11 is an enlarged detail view illustrating in top plan View the mechanism for regulating and cuttingoif the tobacco-feed, the tobacco receptacle and agitating mechanism being removed. Fig. 12 is an enlarged detail view illustrating in side elevation a projecting rib or fin for conducting the greater portion of the tobacco to the forward end of the compressing mechanism. Figs. 13, 14-, and 15 are enlarged detailviews illustrating, respectively, in side elevation, top plan View, and front elevation the mechanism for tucking in the ends of the paper tube. Fig. 16 is a detail view of Fig. 14, illustrating one of the tuck. ing mechanisms in operative position. Fig. 17 illustrates in enlarged detail view one end of a paper tube after the same has been tucked in. Figs. 18 and 19 are enlarged detail views illustrating, respectively, in side elevation and top plan view the mechanism for automatically bringing the machine to a standstill should the paper fail to be fed to the tube-forming mechanism. Fig. 20 is an enlarged detail view illustrating in side elevation the mechanism for clamping and holding the paper tube in position during the filling of the same with tobacco. Fig. 21 is an enlarged detail view illustrating in front elevation the mechanism for holding the filled paper tube in position to prevent displacement of the same at the return movement of the tobacco-feed and for holding the filled tube in position during the tucking in of the other end of said tube and for ejecting the complete cigarette, and Fig. 22 is an enlarged detail view illustrating in section the mechanism for preventing-the backward or retrograde movement of the machine.

Referring to the drawings, A represents a counter-shaft on which are located the fast and loose pulleys A and A and the fly-wheel A Poweris communicated from the powershaft A by gear-wheels A and A to the power-shaft a, of the machine. which is supported at either end by bearings a and a upon the bed-plate a of the machine. On this shaft a are located all of the means for operating the various mechanisms of the machine.

The paper to be used in the formation of' the cigarette is preferably wound on a reel 0;, carried by a standard a", secured upon the bed-plate a From this reel the strip of paper a, is guided over a roller a to the feeding mechanism, as fully illustrated in Figs. 2, 3, and 6 of the drawings. This feeding mechanism, which serves to feed the strip of paper forward for varying lengths or distances, consists, essentially, as illustrated in Figs. 1, 2, 6, and 7, of a table I), supported by the bed-plate a and to which is secured a frame I). A block 5 carried by an arm b reciprocates within said frame, and the under face of this block is adapted to engage the strip of paper a, traveling over the table b. The arm b is pivotally secured to a bail I), held in position by the shafts b and b and guided by a rod b sliding in an extension 0. of the bearing a of the shaft (1. This bail b partially surrounds a drum 12 secured to the power-shaft a,in the periphery of which is arranged a cam-groove b. The bail by means of a roller b", Fig. 3, engages said cam-groove b and is given a reciprocating movement by the cam-groove b by the rotation of said drum. This movement is transferred to the arm 19 and block 6 It is, however, necessary to raise the block from the paper a at each completion of the forward movement and to bring the same into engagement with said paper at the beginning of the forward movement, so as to feed the same forward only. The required raising and lowering of the block b is accomplished by a lever-arm b pivoted at I9 (see Fig. 5) to an extension of the table I). The free end of said arm 19 carries a roller Z9 which by means of a spring Z2 is held in engagement with a cam b, secured to the power-shaft a, while the other end is bent and engages with its forked end Z9 the arm 19 of the block 6 By the rotation of the cam Z1 an up-and-down movement is imparted to the end 17 of the lever-arm Z9 by means of which the arm 11 and block b are raised and lowered and the block is brought into and out of engagement with the paper a, so that the same will be fed forward only as hereinbefore described. In order to decrease or increase the forward travel of the block W, so as to feed the paper forward for varying distances, the block b is movable on the arm 19 and is shifted thereon by the preferred mechanism illustrated in Figs. 6, 7, and 8. The block b is provided with a slot b through which passes the arm 5 actuating the block. On this arm 5 within the slot 19 bears a bar b and this bar I) is held in engagement therewith by a spring 19 engaged by a screw Z9 adjustable in the block 12 The pressure of the spring 6 against the bar b and the arm 12 can in this manner be regulated by said screw I9 The bar Z7 is provided with a projection 19 at either end, and the actuating-arm b has arranged therein notches b. When the block b is moved backward, it abuts against the front end of the frame I) and is thus limited in its backward movement. The actuating-arm b however, moves farther backward and forces the block 5 forward, bringing one of the projections 11 of the bar 19 into engagement with one of the notches I), as indicated in dotted lines in .Fig. 6, thereby locking the block to the arm b The block b which is held in engagement with the paper a by meansof the spring Z1 is now moved forward and takes the paper a, resting on the table I), along with it. This IIO ranged on the main shaft (1.

forward movement of the block b is limited by the frame I), and the block is forced back= ward on the actuating-arm biwhich continues its forward movement after the block has struck the forward end of the frame I). It will therefore be readily seen that the strip of paper a is fed forward a predetermined distance, which distance can be limited or increased by two adjusting-screws 5 arranged in the forward end of the frame 11, against which frame the block b abuts. In order to hold the strip of paper as in position on the table I), it is passed under leaf-springs Z1 which are secured to a bar b carried by the extensions Z9 of the frame I). As the paper is advanced on the table I) by the mechanism hereinbefore described it is fed to a second table 0, arranged alongside or in advance of the table I), and secured thereto by screws 0, as shown in Fig. 6. The paperis then cut by a knife 0 operated by the mechanism illustrated in Figs. 1, 2, and As shown, the knife 0 is pivoted, as at 0 to an extension of the table 0, and by means of a link 0 is pivotally connected to a rocking arm 0 carried by a tubular rocking shaft. (Not shown, but which is of well-k11own construction and arrangement.) The arm or lever c is normally depressed by a spring cland the tubular shaft is connected with a rocking arm 0 the free end of which engages a single-throw cam 0 arranged on the main shaft 0, of the machine. For each revolution of the shaft c the rocking shaft is operated by the arm 0 and elevates the rocking arm 0 which in turn, through the link 0, depresses the knife 0 against the tension of the spring 0 The depression of the knife 0 acting between the adjacent edges of the tables I) and 0, serves to sever the paper. The table 0 is provided with slots 0 in which reciprocates a feeder 0 carried by an arm 0 secured at one end to a rocking shaft, the end of which is shown at 0 and which is lo cated within the tubular rocking shaft. (Not shown.) This solid rocking shaft is operated by an arm 0 which is actuated by a cam 0 ,211-

This cam has its throw-surface so arranged with respect to the cam c that it will operate the feeder c after the paper has been cut. Further description and illustration of this mechanism are deemed unnecessary, as the same is well known. The feeder 0 shifts the cut portion of the paper a transversely over the table 0 and into engagement with a tube-forming mechanism cooperating with a tube holder or wheel cl,

loosely mounted on the shaft (0 of the machine. This tube-holder d, as illustrated in Figs. 1, 2, 4, and 7, consists of a disk (1, provided with a flange or annulus (1 in which openings or molds d are formed. The molds are slotted, as at d, the slot extending through the periphery of the annulus (1 The openings d and slots (Z are so arranged that as the wheel rotates the slot of each opening or mold will be presented successively to the table 0. For this purpose a step-by-step movement is imparted to the tube-holder d by the following preferred mechanism: To the disk (1 is secured a ring d provided with notches or indentations (W at its inner periphery. These notches are engaged once during a complete revolution of the main shaft a by the tooth d of a one-toothed wheel.

at, carried by a shaft d located in a standard 01 secured to the bed-plate a of the machine. The one-toothed wheel d is connected to a gear-wheel (1 located on-the shaft 01 which meshes with a gear-Wheel d, secured to the main shaft Ct. Motion from this shaft a is therefore transmitted to the one-toothed wheel d", which by means of its tooth (Z engages one of the notches 01 imparting to the tube-holder d a movement which brings one of the molds d opposite the table 0. In order to securely lock or hold the tube-holder in each given position, the space 01 between the two notches d in the ring (1 is curved in a radius corresponding to the radius of the periphery c1 of the one-toothed wheel d. After the tooth d is brought out of engagement with one of the notches the periphery tube-forming mechanism is the same as de-' scribedand shown in the Letters Patent No. 636,625, dated November 7, 1899, and consists, essentially, of a shaft 17 to which reciprocating motion is given toward and away from-the tubular openings d of the tube holder at by the bail N. A rotary motion within successive tubular openings is given by means of a gear-Wheel e and toothed sector 6 secured to the drum 12 To this shaft 19 is secured a split sleeve 6, surrounding a rod 6 provided with a rib 6 which, in conjunction with the sleeve 6, clamps the end of the paper fed thereto from the table a. This paper is rolled into a tube by the rotation of the sleeve 6 and rod 6 which tube after completion is released by this rod and sleeve.

For this purposethe sleeve is first opened to release the paper and then both sleeve and rod are withdrawn from the tubular opening 01 leaving the tube therein. During the operation of the tube-forming mechanism the paper is engaged by a knife :0 as illustrated in Figs. 8, 20, and 21, the purpose of which will be hereinafter more fully explained. After the tube hasthus been formed and before it is carried away by the tube-holder d it rests in the tubular opening (1 with both ends of the tube projecting some distance beyond the faces of the annulus (F. The next operation is to tuck in one of the projecting ends of the tube prior to its presentation to the tobacco-fillin g mechanism. The tucking mechanism for 'both ends is the same and consists, essentially, of two parts, one to tuck in thetube from one side and the other to tuck in the same from the opposite side and to force the tucked endsinward into the tube, and so complete the tucking.

Referring now to Figs. 1,2, 3, and 13 to 17, inclusive, upon the main shaft a, of the machine are placed side by side two cam'sfand g. The cam foperates a Wedge-shaped tucker f, which tucks in or makes the first fold into the end of the paper tube from one side, while the cam g operates a latch-shaped tucker g, which tucks or folds in the tube from the other side, which second fold overlaps the first fold, and both folds are then pressed inward by the tucker g. The tucker f is normally held away from the face of the annulus cl of the tube-holder d by means of the cam fas long as a rollerf is in engagement therewith. 'lhis roller is secured to a slide f having a range of longitudinal movement within a standard f secured to the bed-plate a of the machine. To the slide f is fastened a plate carrying at its end an obliquely-arranged blockf engaging a correspondinglyarranged slot f within a cover-plate f, to which the tucker or wedge f is secured. A springf secured at one end to an arm f of the slide f and the other end to a bracket f", which is removably secured to the standard f tends to hold the rollerf always in engagement with the cam f. The cover-plate outsidethe oblique slot f is also provided with two right-angular-shaped slots f en gaged by bolts f secured to bars f, fixed to the upper portion of the standard f and guiding the block-platef When the bolts f occupy the portion f of the slot f the wedgef will be withdrawn from the face of the annulus of the tube-holder d as long as the roller f engages the periphery f of the camf. The portion f of the slotj' serves to guide the cover-plate f and thereby the wedge or tucker f, in a line at a right angle to the standard f while the other portion f of the slots f serves to guide said plate and tuckerf in a line parallel to said standard. The oblique slot f however, serves, by means of the block-plate f and slide f, to' actuate the plate f and tucker f first from right to left and then fromleft to right. When the roller f in the rotation of the cam f reaches the throw f of the same, the slide f is moved toward the camfand the platef", and tucker f is moved toward the face of the annulus by means of the oblique slot f until the bolts or pins f reach the end of the portion f of the slots f by which time the tucker f has reached a position in front of the projecting end of the paper tube and in close proximity to the face of said annulus of the tube-holder cl. The further movement of the plate f and tucker f toward the cam f forces the pins or bolts f into the portions f of the slots f and the tucker now moves forwardly in a direction parallel to the face of the annulus and is brought into engagement with the projecting end of the paper tube and folds or tucks the same inward. As soon as the tuckerf has completed the tucking of one side of the paper tube it then begins its return movement. The slide f plate f", and tucker f are now moved backward away from the cam f, while the latchlike tucker g, having been idle, is now moved forward, following the tucker f. The forward movement of the tucker g is accomplished by the throw g of the cam g being brought in its rotation into engagement with a roller 9 secured to a slide g. This slide g is carried by the standard f and arranged alongside of the slidef and below the coverplate f The slide 9 is provided with a lateral projecting arm 9 to which is pivotally secured the latch-like tucker g. A spring g normally tends to hold the roller 9 in engagement with the cam g, which spring at one end is secured to an arm 9 of the slide 9 and at its other end to the bracket'f". The tucker g is provided with a curved extension g", in which a similar-shaped slot 9 is formed. This slot is engaged by a pinor bolt g of an arm g secured to the standard f in such manner that when the tucker g is moved forward it will first operate in a straight line and then swing sidewise. During the forward movement of the tucker the same is brought into engagement with the projecting end of the paper tube and folds in the same from the opposite side thereof, so that this second fold overlaps the first fold. After this second fold is completed both tucked portions of the paper tube are forced inward by the tucker g, and in this manner the tube at one end is securely closed, said closed end assuming the shape as illustrated in Fig. 17 of the drawings, and is now ready for the reception of a charge of tobacco. The tucker g is now brought back. to its normal position when the throw portion g of the cam g has passed under the roller 9 The tube so tucked is next transferred by the tubeholder to the opposite side of the machine, where the tobacco is fed, measured, compressed, and forced into the tube. Preferably loose granulated tobacco is used for a filler, containing a certain percentage of moisture.

Asshown in Fig. 1 of the drawings, the wedge-shaped tuckerf is located adjacent to the table 0, over which the paper a, previously cut from a strip of paper, is fed into the tube-holder d, as hereinbefore fully described. As the paper has to project some distance beyond the face of the annulus d of the tube-holder (1, said paper is wider than the table 0. By withdrawing the wedge-shaped tucker f from the face of the annulus d by a lateral movement the same is held out of the path of travel of the paper a fed to the tube-holder d, and is thus prevented from interfering with the proper feeding of the same.

IIO

romeo After the paper has been formed into a tube, as described, and has been removed from the path of lateral movement of the tucker f the.

projecting end of the paper tube is tucked or folded by the same-that is to say, by first moving the tucker toward the annulus (Z and bringing the same into alinement with the face thereof in front of the projecting end of the tube, as shown in dotted lines in Fig. 16, and then moving the tuckerin a forward direction.

As illustrated in Figs. 1 to 5 and 9 to 12 and 20 and 2l,inclusive, the tobacco-feeding device is carried by a standard h, supported upon the bed-plate a of themachine, at the top of which standard a hopper m, containing a tobacco-agitating device, is located, as will be presently more fully described. In order to fill the paper tube with tobacco, the same must first be clamped with its open end to a ferrule t', carried by the standard h and communicating with the tobacco-feeding device. For this purpose the paper tube must be shifted forward toward the ferrule 2' until its open end engages the end of the ferrule projecting from the standard h. The mechanism for shifting the paper tube forward consists, as shown in Figs. 1, 3, and 21, of a rod 76, sliding within a bracket k supported by the bed-plate a and within which is 'mounted a spring 79 surrounding the rod is. This spring bears at one end against the bracket and at its opposite end against an arm Z, fixed to the rod 7;, and normally tends to shift the rod is and paper tube toward the tobaccofeeding device. The rod 7c is normally retracted by a lever k engaging a pin is of the same with its forked end 70 the lever being pivoted at the point 1& and being provided at its free end with a roller 70 engaging a cam 70, located on the main shaft a of the machine. During the rotation of the cam the rod 70 with its end k is allowed to shift the paper tube forward and is held opposite thereto in the tube-holder until the open end of the tube surrounds the ferrule 2", as fully illustrated in Fig. 21. As soon as the tube engages the ferrule i the same is clamped thereto by means of the arms 2" and i pivotally secured by the screws 1' and i to the standard h, as shown in Fig. 20. The arms 1) and i are provided with jaws #andii which are normally brought into engagement with the ferrule 'i by a spring 2' Secured to pins or bolts i of the arms 1" and 1' but are held separated from said ferrule d by a bolt 2' of a lever 1 when the same is brought out of engagement with the indentations i arranged in the arms 1 and The lever i, pivotally secured, as at i to the standard h, carries a roller 1", engaging a cam 11, secured to the main shaft a. This cam is pro vided with a single throw i, which allows the bolt i to engage the indentations t' of the arms 2" and 11* to permit the jaws i and i to close and clamp the paper tube to the forrule 1'. This tube is now held-in proper position to receive the tobacco filling and is after completion of the filling released from the ferrule by the cam 11 In case the tube isnot .filled with tobaccothe arm I, secured to the rod 70 and engagingthe paper tube with its bent end Z in the manner illustrated in Fig. 21, will by the return movement of the rod 7c withdraw the empty tube and disengage the same from the ferrule t'. The tube is thus shifted backward and prevented from projecting too far beyond the tube-holder, which would result in the tearing of the same by the second tucker. It will, however, bc tucked by the second tucker to permit the ejector-rod w to force the emply tube from thecarrier d, and thus prevent clogging of said carrier. I

With special reference to Figs. 1, 2, 4, 5, and 9 the hopper m, in which the tobacco is placed, is provided at its lower end with a shaft m, having arms m adapted toloosen or agitate the tobacco, so that the same will be uniformly fed through an opening m into a tobacco-measuring mechanism. Motion is impaited to the shaft m and armsm from the main shaft a by means of the sprocketwheels m and m and sprocket-chain in, The chain, as shown in Fig. 5, is preferably guided over a roller mhrcarried by a bracket b in order to clear certain mechanisms of the machine.

Referring to Figs. 9 to 12, inclusive, the opening m of the hopper m is normally closed by a knife 12, which issecured to a framen', clamped to a reciprocating block 0 by means of a bar 01 which'engages a groove 0 in the block 0 and similar grooves in the lips 0 projecting from said block 0. The bar n? is pivotally connected with the frame n at one end by a screw or bolt n while the other end of the bar carries abutton n, by means ofwhich the bar a can be' lifted at one end and brought out of engagement with the groove 0 of the block when the knife is to be thrown out of action. The tobacco feed is then cut off, as the opening m of the hopper is closed bysaid knife 71. This instantaneous cutting olf of the tobacco feed by simply disengaging the frame it from the block 0 is important in instances when the filling of the paper tubes is to be stopped or the feeding of the tobacco to the same is irregular. Below the knife 71 and within the frame it is located a second frame I), which, however, is not connected with the reciprocating block 0, but is fixed and adjustabl'y secured to the hopper in by means of an adjusting-screw p", engaging the part 19 of the frame p. The bar-like portion 19 of the said frame rests directly below the knife 'n and forms, in conjunction with the extension m of the hopper, a chamber 194, adapted to receive the tobacco coming from the hopperm through its opening m This chamber 19 can be readily increased or decreased in size by sim ply turning the adj usting' screw p which shifts the frame p and the bar 12 away from or toward the extension at of the hop- TIO izo

perm, so forminga tobacco-measuring device,by means of which the amount of tobacco 19 is opened at its upper end by the knife n andclosed at its lower end by the block 0. The tobacco will fall. into the m easu ring-chainher and fill the'same and be fed into a coinpressing-chamber h as soon as the block .occupies the position shown in Fig. 9, in which position the'openin'g m from the hopper m into the measuring-chamber will be closed. As soon as the tobacco leaves the measuringchamber 10 a certain portion thereof. strikes inits fall a rib 0?, projecting from the reciprocating block 0, and on account of. the oblique position of said rib a greater amount of tobacco is conducted to the forward portion of the chamber h for a purpose to be presently described. The block 0 is guided between a table It, integral with the standard h, and the projection m of the hopper m and receives its reciprocating movement from a cam-groove 0 provided in a disk 0, se-

cured to the main shaft CL of the machine.

In this cam-groove 0 travels a roller o carried by a link 0 connected to a projecting arm 0 of the block 0. The table'h is provided with an indentation 71 within which an ejector-rod r is adapted to slide, which, however, during the feed of tobacco to the table h is withdrawn therefrom. Directly above the indentation h and within the cham ber h is arranged atobacco-compressingslide s, provided at its lower face with a semicircular groove 5, which, in conjunction with the semicircular groove h forms a more or less circularopening when the slide 3 is lowered. The mechanism reciprocating said compressing-slide s in a vertical plane consists, preferably, of a slide 8 having a range of movement within the standard It and is pivotallyconnected at its lower end to a link 8 which in turn is movably connected to a standard 8 as at .8, which standard is secured to the bed-plate a of the machine. A roller 5 carried by said link 5 intermediate of its ends engages a cam-groove 8 arranged in the disk 0 which groove in the rotation of said disk imparts to both slidess and s a reciprocatory movement. The slides are connected with each other bya bolt 8, the head 8 of which freely turns in the compressingslide 8, while the threaded portion of said bolt passes through a bushing s integral witha disk 8. This bushing is located within an elongated opening 3, arranged in the actuating-slide s and both slides are clamped together by the bolt 8 and a nut s bearing against the disk 8 of the bushing as will be readily understood in connection with Fig. 9 of'the drawings. The bolt 3 is eccentrically located in the bushing which bushing engages the elongated slot 8 in the slide 8 as illustrated in dotted lines in Fig. 10. It follows, therefore, that when said bushing is turned within said slot the tobacco-coin pressing slide a is correspongingly raised or lowered within the compressing-chamber 72 and will in its downward movement more or less deeply engage the groove h The tobacco which has been fed into the compressionchamber h and is resting on the table h is moved into the groove k and in the space below the compressing-slide s by the forward movement of the block 0, whereby a greater portion of the same, owing to the rib 0 has been conducted to the forward end ofthe groove 71 After the block 0 has reached a position in close proximity to the slide 3, in which position the tobacco fills the groove 7L and a space below the slide 8, the slide sis now operated and compresses the tobacco in its downward movement toward the groove h By this compression the tobacco is brought into a shape in which the same can be readily received by the paper tube, which has been clamped to the ferrule t', communicating with the groove 779, as shown in Fig. 21 of the draw ings. With reference to the foregoing description it will be understood that by raising or lowering the compression-slide s with respect to the operating-slide s by means of the bushing s the degree of compression of the tobacco can bereadily regulated. This feature is important, since, due to anincomplete or too great a compression, the tobacco will either be too loose or too hard and will therefore not be in proper condition for the ejection of the same, which would naturally tend to further compress the tobacco. By having a greater amount of tobacco fed toward the ferrule i the tobacco at this point will be in a greater state ofcompression than that occupying the opposite end of the groove h This irregular compression will, how ever, be compensated for and equalized when the compressed tobacco is ejected from the compression-chamber by the plunger-rod r entering the chamber opposite the ferrule t. This rod 1 by abutting against the tobacco in its forward movement toward the tube-holder will compress this end of the tobacco, and so make the compression of the same uniform throughout its length. The compressed tobacco is now fed into the paper tube by said plunger-rod r in the usual or wellknown manner, a

With special reference to Figs. 1 and 3 of the drawings the plunger-rod r is secured to a slide r" of a bracket 1, bolted to the bail b. As previously described, to the bail b is imparted a reciprocatory movement by means of the roller Z)" and cam-groove b arranged in thedrum If. The forward movenientiinparted to the plunger-rod 1' is,.however, not sufficient to shift the tobacco the proper distance forward. In order to complete the forward movement of the plunger-rod 1' after the same has been shifted by the cam-groove b ,the drum 6 is provided with an auxiliary cam b flwhich when the roller b has reached the straight portion of the cam-groove b engages a roller r secured to a slide 0-, to which the plunger-rod r is fastened, and imparts to the same the necessary end movement, and so completes the forward movement of the plunger-rod r. This forward movement at intervals has the beneficial result that the tobacco which might cling to the plunger-rod oduring the ejection thereof is loosened therefrom and is so prevented from being drawn back into the compression-chamber h". To guide the slide r properly within the bracket 1- a second rod r is secured to the same. The springs 1' and r arranged on the rod 0' and plunger-rod r retract this plunger-rod to its normal position as soon as the auxiliary cam Z) has passed the roller r of the slide 1*, as will be readily understood in connection with Fig. 2-3 of the drawings. The standard 71 carries a receptacle 1, in which preferably cotton-waste t is placed and through which the plunger-rod 0* passes. The object of this cotton-waste is to keep the plunger-rod clean and to remove therefrom any particles of tobacco which might adhere thereto.

In order to prevent displacement of the filled paper tube within the tube holder through. the plunger-rod 1* when the same withdraws from the paper tube, a clamp It is provided which engages the filled paper tube and holds the same in position. The clampu, as

shown in Figs. 1 and 21, is pivotally secured,

as at to, to a plate of the bracket 7.2 and is normally held out of engagement with the paper tube by means of a spring a pressing the arm it thereof against a screw or bolt 1L3, secured to the plate 10 As soon as the arm I, carried by the rod 7a, is withdrawn from the ferrule t, as hereinbefore fully described, the same engages the arm a and brings the clamp it into engagement with the filled paper tube. After this tube has been filled with tobacco, the tube-holder (Z is advanced a step to bring the open end opposite the tucking-wedge and tucking-latch, which are operated in the same manner as the wedge and latch which tucked the other end of the tube prior to its being filled. A further description of the tucking operation and the tucking mechanism is therefore deemed unnecessary. In order to tuck in the open end of the paper tube, it is necessary, however, to shift the tube slightly forward in the tubeholder d, so as to bring this end of the tube into proper location with respect to the tucking mechanism. This shifting is accomplished by a spring-controlled rod 0, operated stop the machine in case of the paper not being fed to the tube-holder cl, owing to the improper working of the feeding device or the paper being torn, is illustrated in Figs. 18 and 19 and consists of the following mechanism: As hereinbefore described, during the feeding of the paper from the table 0 into the tubeholder d the same is engaged by a knife 00 carried by a lever x, pivotally secu red, as at a, to a bracket 00 of the standard h. The lever m intermediate of its ends is provided witha roller m normally engaging by theintervention of a spring a single-throw cam :12 on the main shaft a. This spring 00 is secured at one end to an arm 0f the lever :1: and at the other end to the table 0. As soon as the roller 420 comes into engagement wit-h the cam portion 0: of the cam x during rotation of the same the spring 41: tends to lift the end of the lever :10 carrying the knife x which,however, is limited in its upward movement by the paper crossing the space between the table 0 and the tube-holder d. If, however, the paper does not obstruct the path of the knife 00 the lever a; will further ascend and bring a pawl m supported by a pin m engaging a slot of the pawl, into engagement with the teeth as, arranged in the periphery of a disk 03 located on themain shaft a. These teeth in the rotation of the disk 00 willshift the pawl 068 and a slide 00 joined thereto, backward and operate a bell-crank lever 00 connected by'a chain at (see Fig. 1) to a belt-shifter an, engaging a belt. (Not shown.) The belt by the movement of -the belt-shifter is shifted from the fixed pulley A to the loose pulley A and the machine is brought to a standstill. In order to lock the slide 00", which is carried by the bracket 00 into an operative position, the slide is provided with a groove 00, into which by means of a spring at the end 50 of a latch as is forced as soon as the slide is shifted.

The preferred mechanism to prevent retrograde movement of the machine is illustrated in Figs. 1 and 22 of the drawings. For this purpose the gear-wheel A is loosely mounted on the shaft A and is provided with lateral projecting teeth y, engaging the teeth y of a sleeve 11 which is fixed to the shaft A, yet slidable thereon. As shown in Fig. 22, within the shaft A is arranged'a spring if, connected to a bolt if of the sleeve 11 normally tending to hold the sleeve with its teeth in engagement with the teeth y of the gear-wheel A As long as a movement in the proper direction is imparted to theshaft A this movement by the gear-wheel A will be transmitted to the gear-wheel A and main driving-shaft Ct. If, however, the shaft A isturned backward, the wheel A will be disengaged from the sleeve 1 and the machine brought to a standstill.
