This invention relates to apparatus for the simultaneous production of a numberof cigarettes. According to the invention a strip of cigarette paper is unwound'from a-bobbin'by meansv of a transporter and broughtv into a position opposite 'to a number of members in which the paper, after it has been divided by simultaneously'mov'ed knives into a number of parts corresponding to the number ofcylin- 10 drical cases can he slipped simultaneously into the said cases 'for'the preparation of the cigarettes. To each of these cases there belongs a so-called ram, which is so constructed as to be movable up and down and also rotatable and which rolls up thepaper in the case into a tube, tamps the tobacco one or-moretimes, and expels the cigarette from the case.

The feeding of the paper into the desired position over the cylindrical cases is obtained by means of periodically moved endless steel bands which are. provided with preferably resilient clamps, the mutual distances of which correspond to the length of the paper necessary for the number ofcigarettes to be simultaneously prepared, duringeach period of operation which grip the paper coming from the bobbin or storage roll and guide it to the cigarette members.- f V According to the invention the group of cylindrical cases consists of a row of cylinders, each provided with a gap which is provided along a generating line and into'which, for all the cylinders at the same time, a piece of the cut-up strip of cigarette paper is pushed. a v 1 This pushing in of the paper is effected by means of pushers which are movedsimultaneously with the cutting knives and; which push the paper immediately after it is cut ofl along Above each case-is arranged amovable fill- 7 ing hopper, which is provided witha prolongation piece which islocated in the centre line of the case and around which one of the outer ends of the paper sleeve is coiled, the paper being held fast if necessary in case of need by a nipping device round the extension plece.

"-If'the apparatus is being utilized forthe preparation of cigarettes whichare to be folded in at one or both ends, the'cylindrical cases are provided according to the invention at one or both ends with folding bodies, the movements of which proceed simultana The movements of the folding apparatus may accordingto the invention be effected in such a way that at the end of the member at which the introduction of the ram does not A take place, the paper tube already formed is v is guided into the cylindrical cases. a v

For the feeding of the tobacco into the cylindrical cases there isfitted a distributing- 1 roll, which isprovided on its periphery with a number of grooves for each cylindrical case corresponding to the number of stadia on which the fillings of thepaper tube isefiected. The grooves move during the rotation ofthe;- roller in their highest. position past apertures in the tobacco storage hopper and thereupon discharge their contents in thelowest polsition into the hoppers that feed the paper tu es.

v The invention will now be more fully de- :50

scribed in reference to the constructional example illustrated in the accompanyingdrawings. Althoughin these drawings a modified construction is indicated only in the case of a 'smgle element it is clear that many of the parts can be constructed in some other way without abandoning the basic idea of the invention. i

Figure 8 illustrates a pair of shears.

Figure 16 shows the fastening of the fame.

Figure 17 is a plan, and Figure 18 a rear elevation of one form of the cylinders.

Figure 19 illustrates the cams on the large cam disc, and r Figure 20 the fastening of the cams.

Figures 21. 22 and 23 show the tobacco roller with adjustable capacity and accessories.

The machine illustrated in the drawings serves for the continuous preparation of twenty cigarettes at a time. The paper is guided along the cylinders, whereupon it-is cut up by the shears into a number of pieces equal to the number of cigarettes to be prepared.

After the pushers have then pushed the paper through tangential gaps into the cylinders, the rams rotate the paper into tubes. According to this constructional example the tubes are then folded in at the lower end. Then commences the filling of the tubes in one or more operations, and the tamping of the tobacco, whereupon the tubes are folded in at the top by means of folding arms, and the cigarettes are pushed out of the cylinders by the rams.

The motor (Figure 1), by means of belt pulleys 2, 3, 4 and 5 drives a shaft 6. From this main shaft 6, all the movements of the machine parts are obtained.

The paper supply (Figures 1, 2, 3, 5 and 6) By means of bevel wheels 7 and 8 is driven a shaft 9, which transmits its motion by meansof belt pulleys 10 and 11 and bevel wheels 12 and 13 to the roller 14 of a papertransporter.

It is clear that the paper is to be supplied only during a part of the period of production. The pulley 10 is therefore provided on part of its periphery with a pad, which, during part of the revolution of the shaft 9, by greater tension of the belt, effects the trans mission to the pulley 11, while during the remainder of the time the belt merely hangs loosely against the pulley 10 and no transmission takes place.

On the

rollers

14 and 15 there run two endless steel bands 20. Over a pair of rollers 16, 17, there likewise run two endless steel'bands 21. The paper, which is supplied from a bobbin 18 over an oblique guide 19, is carried along by resilient clamping between clamps 22 secured between the bands 20 and bars 23 fitted between the bands 21 and arranged in sets as shown. Obviously the lengths of the

bands

20 and 21 are to be multiples of the distance between successive clamps 22 and between successive pairs of bars 23.

The clamps 22 and the bars 23 are made of india-rubber or other preferably resilient material.

A device not shown provides for the automatic stoppage of the machine in the event of the paper breaking or of the paper on the bobbin being consumed.

The cutting of the paper to size (F z'gures 1, 2, 3, '7 and 8) A chain pulley 25, secured'to the sh aft 9, by means of a chain pulley 26, drives a shaft 27. Cam discs 28 arranged on the latter move a rod 30 to and fro by means of levers 29.

To this rod 30 lying in and guided by sleeves in the frame are secured readily removable arms 31, which move shear blades 32. Between these blades 32 and shear blades 33 the paper is cut off. Like the movable shear blades 32, the fixed shear blade may be secured in a simple manner to the corresponding cylinder 41, so that the shears can easily be removed as a whole.

.It may be noted that the

lower bands

20 and 21 normally occupy the space below the shear blades .(Fig. 8).

The pushing 0f the paper into the cylinders (Figures 1, 3 and 7) Cam discs 35 secured to the shaft 27 move by means of levers 36 a rod 37 by which the pushers 39 pivoted to arms 38 are moved to and fro. Accordingly during the outward stroke of the pushers 39 the cut-off paper 24 is pushed into gaps 40 in cylinders 41.

The paper 24 may be cut off in such a way that a small margin projects past the gap 40. .The pushers 39 then make a small fold in the paper when push ng 1t m.

The rolling up of paper (Figures 1, Z, and 9 1 After the paper 24 has been pushed into is then rotated to turn the paper into a tube, 1

and the T3111 is raised again.

tobacco The rotating of the rams (Figures 1, 3,6

and 9) the upper end it then embraces the lower end a of a hopper 4'8. 7

By this means the resultis obtained that y the ram. can easily enter the sleeve 7 without telescoping the paper. Another object of this will be described later on. After the folding of the tube it is folded in at the bottom by folding arms (see later) before the tobacco is supplied.

The up-omcZ-down movement of the rams (Figures 1, J; and?) The up-and-down movement of therams is effected as follows By means of a cam disc 49 mounted on the shaft 6.and a roller50 a bar 51 is moved up and down at moments tobemore accurately indicated hereafter, whereby the rams 42 rotatably secured to a cross bar 52' likewise go up and down owing to rods 53. 1 The adjustment of the duration 0f the movements of the rams (Figures 1', 9, 19041 0320) 145, which are secured to the discwith bolts 147 passing through slots 146.

The cam members 145' comprise on their peripheries portionsthat overlap-in such a way that the" roller 50, inthe case of a more or less open or separated arrangementof the cam members,"always rolls easily over the cams. v s V It is clear that by this 'adjustmentof the cams the duration of the cams can be controlled.

The adjustment .the stroheo f the rams (Figures 1 amt?) V For the purpose of adjusting the stroke of the rams for difierent kinds of tobacco, or when, owing to adjustment of the tobacco roller, there is-a larger orsmaller amount of present, the following device is fitted. j p s To a rock shaft 138 is secured an eccentric 139. According to the position of this cccentric 139, during the raising by the cam disc 49 of the roller 50 secured to bars 140, a

link 141 will bring thebar 5 1, and therefore the rams 42, into a higher or lower position.

The rocking of the shaft 138' is obtained movements of the r the action of cams or a cam disc 144 secured to the shaft 6 against a roller 143 fitted to a lever 142; 1

'The disc 144, like the disc 49, comprises readily removablecams. According to the height chosen-for these cams, the shaft 138 1s rocking to a greater or. less extent, and,

thus a larger or smaller adjustment of the stroke of the'rams takes place.

The ewprmsz'on 0f the e'mtz'ambber (Figures 1 and ,9)

'9) and'therefore follows the up-and-down movement of the rams. One arm 61 of levers 6162 loose on .theshaft rest by their own weight against segments 63. The con rings dition now under consideration is when the cross bar 52, and therefore the rams 42, are in their lower positions.. Upon the shaft27 is'mounted at each end a cam disc 64. Each of these, discs 64 presses against a lever 65', so that their cams, by means ofsystems of levers 65, 67 and link 66, cause the segments 63 arranged; on a continuous shaft68 to swing to and fro. The shape of these segments 63 is such that whenthe rods 65 are pushed away by thec'am; disc 64,

and hence when the segments 63 rotate in the direction of the arrow,the arms 611are rotated round the shaft60 in the direction of the arrow, 'so that forks 62 "thereon press down the bushes 47, and this movement, as has alreadybeen described, results in the eX- :pansion of the indiarubber rings. I V The tobacco feed (Figures 1, 2, f; and 10) The cam disc 49 comprises engaging cams A tobacco-feeding roller 70 secured to a shaft69 is driven from. the shaft 27 by means of chain pulleys 71 and 72. The

grooves 74 in the distributing'roller 70 and supplied to the sleeves by hoppers 75'and by. the :hoppers 48 placed abovethe cylintobaceo roller 70rwhich distributes the tobacco in quantities required for the filling of the paper tube in each cylindrical case. To

this end the roller is provided for each cylindrical case with a number of grooves corresponding to the'number of stadia in which the filling of the paperitube must be effected.

The cubic measure of these grooves is adjustable according to the size'of the paper tube. Therefore the roller is provided with two rings for each cylindrical case,'liaving jeach over a quarter .of the periphery a latorally prOJecting" piece 149, which is reduced on the periphery inorder to be covered by a tobacco in a storage receptacle 73 isfcarried round by r (iil plate 150. By displacing the rings 148 with respect to each other the length of the grooves can be enlarged or reduced. The grooves for each cylindrical case are separated by a dis tance piece 151, secured by small screws 152 to the roller 70.

By means of the screws 153 the depth 0 the grooves 74 is easily adjusted.

The tamping 0f the tobacco and the removal of the finished cigarettes (F ignres 1, l; and 9) After complete or partial filling the tobacco is tamped by the rams 42, the rams raised again, and the finished tubes folded in at both ends in a manner to be described more fully, are thrust out of the cylinders by the rams, which are again moved down. The cigarettes are then guided away through a discharge channel 76. 1

The folding in of the paper tubes (Figures 1, e, 11, 12, 1s and 14) Before the tobacco is supplied the tube must obviously be folded in at the bottom. This is effected by a preferably flat folding arm After the complete filling the tube is also folded in at the upper end, by a preferably fiat folding arm 78, whereupon, at the same time it may be, two folding arms 79 and 80, preferably with a somewhat sharp edge, press the paper inwards from above and below still more, so the tube finally becomes closed.

As is clearly evident from Figure 11, the folding in is effected by means of the'

arms

77 and 78 on the descent and ascent respeclively of a shaft 81, and by means of the arms 79 and 80 on the ascent of a shaft 82 and the descent of a shaft 83 respectively. Fuller consideration will now be directed'to the source from which these movements are obtained.

Upon the shaft 27 there is in the centre a disc 84, provided with a peripheral groove 85, in which a roller 86 can slide. By this means a lever 87 receives an oscillating movement about a shaft 88. This movement is trans mitted by

rods

89 and 90 to

shafts

93 and 94.

On the other ends of these

shafts

93 and 94 are mounted arms 95. which, by means of rods 96, move a batten 97 up and down. The movement of this batten 97 is transmitted by the pivoted bar 98 to the shaft 81, whereby ultimately the folding in of the paper is obtained by the

arms

77 and 78.

Upon the shaft 27 are further mounted two discs 99 with lateral cams 100, which produce the resultthat during the rotation of the shaft 27 shafts 101 rotate to and fro through a small angle, because the cams 100, at each revolution of the shaft 27, strike against

cams

102 and 103 mounted on the shaft 101.

On the other ends of the shafts 101 are mounted levers 104 which are thus set in oscillating motion by the rotation of the shaft 27. By the rotation of the shafts 101 the descent of links 105 is caused and thereby a batten 107 is pulled down, and also the simultaneous ascent of links 106 by which a batten 108 is pushed up. To these battens 107 and 108 are secured for each cylinder the shafts 83 and 82 respectively, so that during the rotation of the shafts 101 the folding arms 79 and 80 entirely fold in the sleeves.

The raising of the hoppers (Figures 1, 3, .9 and 12) Before the tubes can be folded in at their upper ends, the hoppers 48 must be removed. The paper has already been rolled round the hoppers at the top during the rolling up, so that, the hoppers 48 must first be removed before the folding in can be effected.

For this purpose there are secured to the shaft 27 two cam discs 109, which by means of levers 110 and links 111 can move a batten 112 up and down. To this batten 112 are secured the hoppers 48, which are thus raised at the desired moments.

The gripping 0f the paper (Figures 1, 3, .9, 12 and 13) It has already been shown that the paper is rolled round the lower ends of the hoppers 48. In order to guard against the rams 42 crushing the sleeves (or tubes) and pushing same out of the cylinders, the tubes are clamped against these hoppers 48 at the top, where they have been rolled round the hoppers 48, by a gripper or pair of tongs, consisting of-

arms

113 and 114. This device may be omitted if desired.

In order to enable thetubes to be folded in at the top, the grippers must releasethe tubes at a certain instant. This is effected by the

arms

113 and 114 being then rotated by

projections

118 and 119 respectively on

battens

116 and 117 respectively about pivots 115. The closed position, as illustrated, of the grippers is obtained by tension springs 120 being secured between the

arms

113 and 114 of adjacent grippers. 1

The moving of the

battens

116 and 117 is obtained in the following manner:

On the outer ends of the batten 97 are mounted rods 125 provided with adjusting screws 126.

During the ascent of the batten 97 the rods I 125 ascend freely through holes 122 in levers 121. During the descent, however, the levers 121 are pressed down against the action of springs 124, whereby the above-mentioned

battens

116 and 117 are pushed away by projections 128 in the directions of the arrows, whereby, as above described, the nipping

arms

113 and 114 rotate up against the action -of the springs 120.. When the battern 97 ascends againthesprings 120 and 124 resume theiroriginal condition.

The of ramsof anotherlc'ind Instead'of the ram 42 previously described, a ram 127 may be employed. A

The ram 127 centres itself by a. cone 129 in .a plate130 and is provided with azstripj 1280f fibre orothermaterial. A spring is can be adjusted by means of apositioning screw 155. V The exchangingof the fibrev of-the under part ofthe ram can be effected by knockingout a'keyor wedge156.
