CIGARETTE TUBE AND MOUTHPIECE MACHINE.

To all whom it may concern Be it known that we, JULIEN GUENIFFET and J ULns l IoAULT, citizens of the Republic of France, residing in Paris, France, have invented certain new and useful Improvements in Cigarette Tube and Mouthpiece Machines, of which the following is a specification.

This invention aims to provide an improved machine for making inouthpieees of a peculiar character and fitting them to cigarette tubes so as to form complete tubes with mouthpieces in place, ready for the subsequent insertion of the tobacco.

The machine makes an excellent mouthpiece of a style hereinafter described in detail, at a very high rate of speed or output, and the mechanism is of the greatest reliability and simplicity consistent with the operations to be performed.

The accompanying drawings illustrate an embodiment of the invention.

Referring to the embodiment of the in vention illustrated. the paper for forming the mouthpiece is drawn from a roll A, that for forming the cigarette tube from a roll B, and a sliver of cotton is drawn from a horizontal coil of cotton C. The mouthpiece paper, which is of moderate thickness, as shown at Fig. 2 is first out along its edge to form teeth D, pointed for a purpose hereinafter described. As the strip of mouthpiece paper advances the teeth D are bent downward to the position shown. Thereafter the strip is cut into lengths each suflicient for one mouthpiece, as shown at the left-hand end of Fig. 2; and these lengths are coiled or rolled so as to bring the teeth D inward to form a partial diaphragm across the mouthpiece in the manner indicated in Fig. 3. Thereafter a plug of comparatively loose filtering cotton is forced into the mouthpiece to the position of Fig. l, the spring of the teeth D causing them to enter the cotton plug E so as to hold it in place. The mouthpiece which I designate as a whole by'the letter F, is then introduced into the cigarette tube G of the usual thin or of any other suitablepaper, and the tobacco H is inserted through the outer end of the tube, pressing and holding back the plug E of cotton and causing the teeth D of the paper to enter the cotton more firmly. The teeth D when the mouthpiece is first rolled, preferably incline slightly toward the outer end of the cigarette, so as to be forced into the cotton. as shown in Figs. 5 and 6, when the cotton is pushed toward the inner end by the tobacco.

The mechanism for making the cigarette tube illustrated is of a known type. The paper B therefor comes from the roll shown at the right of Fig. 7 passes through a print ing mechanism H for printing thereon a monogram or other device in any desired number of colors, and passes thence to a former J and a crimping roller K and to a pair of shears L by which it is cut into suitable lengths indicated individually by the letter G. The tubes G are then supplied successively with mouthpieces tightly rolled and the combined tubes and mouthpieces are passed through the unrolling mechanism which loosens or spreads out the mouthpiece until it grips the inner surface of its tube firmly, after which the thus completed tubes with mouthpieces are discharged.

The shears L have their blades mounted on a pivot M and pressed together by a spring N between the arms O and O of the shears. For opening the shears a short shaft P is used which is provided with arms carrying opposite rollers Q Q which spread the arms or allow them to come together as the shaft is oscillated. The shaft P is oscillated by means of an arm R carrying a roller which bears against a longitudinally extended plate S carried on the upper end of an arm T, which is fixedly pivoted at U and which carries a roller in engagement with a cam V mounted on a shaft W extending from right to left above the table X. The shaft M of the shears and the shaft P for opening them, are mounted on a slide Y which travels from right to left along a guide Y, the roller on the arm R, however, being always in contact with the elongated plate S, so as to be capable of operation thereby. When the cam V rotates with its circular portion engaging the roller on the arm T, this arm is held up, the plate S is held forward and the shears are held open. At the low points of the cam, however, the spring Z pulls down the arm T and releases the opening device so as to allow the shears to close under the action of the spring N. At the same time that the alternate opening and closing ofthe shears. are taking place, they are reciprocated so as not to interfere with continuous forward movement of the paper B or of the completed tube G. The cam V has two successive depressions a and 6, between which is a slight elevation of less radius than the main portion of the cam, which serves to clear the blades from the paper; the blades remaining sufficiently close together to engage the rear end of the cut-off tube and push it forward. During the operation of the scissors the forward end of the cigarette tube is engaged upon the guide tubes hereinafter referred to.

From the shears the tubes G are successively introduced upon guide tubes 0 of thin sheet metal which are mounted, eight of them, upon a carrier (Z on a central rotating horizontal shaft 6. The tube G is introduced upon the guide tube 0 which is at the highest point of the rotating carrier. The guide tubes 0 have beveled outer ends as shown to facilitate the application of the cigarette tubes thereupon. Between the shears L and the ends of the guide tubes 0 is a stationary guide comprising a half ring f adjustably fixed on the frame of the ma chine, and a forward half ring 9 which is mounted on a depending arm on a shaft 72 (Fig. 13) which is oscillated at frequent intervals to remove the forward half ring 9 when the carrier (Z is to advance with the cigarette tube G. When the tube G arrives on its guide tube 0, there is already within the guide tube a coiled mouthpiece without cotton. In the next position to which the tube is turned the cotton is introduced into the mouthpiece. In the third position the cigarette tube and the mouthpiece are ejected to the right, the completed tube in its ejected position being shown at 7'. The guide tubes 0 ar provided with light springs 1: pressing against their outer faces to hold the cigarette tubes thereon with slight friction. The ejected tubes j rest upon a table or support Z adjacent to the unrolling cylinder m. The position to which they are moved in being ejected is limited by a stop to carried by the member a at the opposite end, and which is adjustably mounted upon the fixed portion of the machine. From the support Z the tube j is advanced by means of a pusher 0 into the space between the unrolling cylinder m and an approximately concentric unrolling plate 10. The pusher 0 is mounted on an arm 9, the pivot 1" of which is mounted on the fixed portion of the machine; the arm Q is retracted by means of a spring 8 connected to said arm and to the arm of an ejector hereinafter referred to; and is advanced by means of a cam t on a shaft u. The member 72 is of the bent shape shown in Fig. 12, and carries an overhang ing part 11 for preventing the tube from umping up, and also a stop w which is adjustable along the member '0 to limit the lengthwise movement of the tube.

The unrolling drum 4% is rotated continuously in the direction shown by the arrow in Fig. 11, and has a roughened surface to grip the tube. .The unrolling plate p is mounted on an arm 00 on the fiXed shaft of the drum, and is adjustable toward and from the drum for tubes of different diameters. -The cigarette tube is advanced into the space between the drum and the plate and turns backward on its own axis as it is carried forward; the distance between the plate and the drum being made larger at the entrance to facilitate introduction of the tube. The plate 7; terminates at the lower forward side of the drum, and the tubes y" with the mouthpieces unrolled so as to fit tightly in them, drop on a supporting plate 3 provided with slits in which reciprocate fingers a. Each tube is first dropped betweenthe retracted fingers z and an elevated central portion of the plate y. The fingers thereupon advance and push or roll the completed tube into the bottom of the box 50. Introducing them into the bottom of the box insures their being placed in regular parallel positions as indicated, so as to facilitate the handling of them. The fingers are carried on arms 51 fixedly pivoted at their lower ends, retracted by a springs and advanced by means of a cam 52 on a shaft 53.

The mechanisms for rolling the mouthpiece, for introducing the cotton, for inserting the mouthpiece into the rotating carrier (Z and for ejecting the mouthpiece and tube from said carrier, are located at the angle between the lines of travel of the mouth piece paper and the tube paper as indicated in Fig. 1, the principal parts of these mechanisms being covered by the receptacle carry ing the coil C of cotton.

In Fig. 8 the tubes which I designate ge nerically by the letter 0 are lettered c 0 0 &c., as indicating the successive positions which they assume in the intermittent rotation of the carrier. The cigarette tube, as already stated, is applied to the guide tube 0. Simultaneously cotton is introduced into the guide tube 0 the tube, mouthpiece and cotton are ejected at 0 and a new moutlr piece without cotton is introduced at The ejector from the rotary plate d consists of a rod 54: (Figs. 7, 10 and 13) en larged at the end within the guide tubes 0 and having an upwardly projecting fin which passes through a slit 54 in the guide tube a sufficient distance to engage a cigarette tube and push it off the guide tube. The slit in the guide tube 0 comes uppermost in the ejecting position and the ejecting rod 5a is advanced and retracted while the rotary carrier is stationary. The rod 54k is mounted at its rear end on a slide 55 which has a laterally projecting pin passing through a slot in the guide 56 in which the slide moves, this pin 57 being engaged by a slot in the upper end of an arm 58 (Fig. 7) which is pivoted in the middle and has its lower end provided with a roller running in a cam groove on the drum 59 which is rotated by a shaft 60 arranged below the table, and carrying cams for other purposes hereinafter referred to. The same arm 58 has a second slot in which lies a pin 61 projecting through a slot in a guide 62, and connected to a slide 63 running in said guide, and this slide carries at its end a blade ea which projects into a slot in the side of the mouthpiece-rolling barrel so as to eject the mouthpiece from said barrel after the mouthpiece is rolled, as hereinafter described more in detail.

' The coil C of cotton is carried in a pan 65 loosely and leads outward therefrom first over an upright guide 66 at the center, thence downward over a guide roll 6'7 and between a pair of brake or tension rolls 68-69 and into a vertical tube 70 having a slot at its left hand side through which enters a grip ping device which draws the cotton forward a determined length. The length of cotton thus projected out of the bottom of the tube 70 is cut off by a pair of shears 71, 72. This cut-off piece of cotton constitutes the plug which is to be pushed into the mouthpiece. It rests when out ofi upon a ledge 73 at the entrance to a short tube 74 in line with the guide tube into which it is to be introduced. A pusher 75 consisting of a rod small enough to enter the rolled mouthpiece easily, is supported at its rear end from a bracket 7 6 which is attached to the slide 55 which carries the ejector 54:, so that the rod 75 advances and retreats simultaneously with said ejector. The length of the rod 75, however, is such that in its advanced position its end merely engages the cotton plug and advances it to the position of the teeth in the mouthpiece as hereinbefore described.

The roller 68 is grooved and the roller 69 is roughened on its edge and arranged to press the sliver of cotton G into the groove in the roller 68; the two rollers being held or drawn together by means of a spring 77. The lower roller 69 is mounted upon a fixed upright 78, which is provided with an oblique upward extension, in the end of which is a shaft 79 carrying an arm 80 which supports the roller 68. The shaft 81 is given an intermittent rotation for feeding or permitting the forward feed of the lower end of the cotton. This shaft extends to the left hand side of the machine as shown in Fig. 13, where it is provided with a ratchet wheel 82 actuated by a pawl 83 on the end of an arm 84 mounted loosely on the shaft 81 and oscillated by an arm 85 connected to a link 86 which is connected to a crank pin on a gear 87 on a continuously rotating shaft 88. The pawl 83 is provided with a handle by which it may be thrown back to inoperative position, thus stopping the feed of the cotton and allowing the machine to make mouthpieces without cotton.

The shaft h which operates the movable half ring 9 of the supplemental guide through which the cigarette tubes are guided on to the guide tubes 0, is actuated also from the same shaft 88. Mounted on the back, or right hand side of the gear 87, is a cam 89, on the top of which rests a cam roller on an arm 90 carried on the shaft 71. The half ring 9 is carried directly on a short arm 91 which is pivotally and laterally adjustable upon the end of an arm 92 on the shaft h, so that the half ring may be adjusted accurately to the desired position. When the arm 90 on the left hand end is raised by its cam, the half ring is moved down to close the guide, and vice versa. The shaft is turned backward to open the guide by means of a spring 93 connected to an arm on the shaft, and to a fixed part of the machine.

The cotton sliver C at its lower end enters the vertical tube and is drawn down through said tube by means of a roughened grip or blade 94, which enters through the upper part of a slot 95 therein, grips the cotton within the tube by pressing it against the opposite face of the tube, and then moves downward carrying the cotton with it and forcing the lower end of the sliver out of the tube; after which the gripping blade is withdrawn, lifted and reapplied at the top as before. The upper position of the blade before entrance into the tube, is shown in Fig. 13 and its position after entrance and downward movement, is shown in Fig. 17. The blade extends upwardly, is pivoted at 95 and has above its pivot an arm which is connected by a spring 96 with a fixed point, so that the lower effective end of the blade is pressed forward by the spring. The pivot 95 of the blade is in the free end of an arm 97 which is oscillated by means of a link 98 connected to the outer end of an arm 99 on a shaft 100 which has an opposite arm 101 which is given a vertical oscillation by means of a rod 102.

The forward edge of the gripping blade 94 is engaged by a roller 103 on a slide 104 which slides through a bearing 105 fixed on the table and which at its rear end is-provided with a roller 106 engaging the face of the cam 107 which rotates on a shaft parallel with the slide. The cam is timed to pull back the slide 104 and to retract the grip;

ping blade when the latter is lowered, after which the arm 99 rises, liftin the blade and the cam 107 releases the slide and permits the spring 96 to press the blade in again into engagement with the cotton, whereupon the arm 99 moves downward carrying the blade with it, and the previous operations are repeated. c

The mounting and operation of the shears 71, 72 are indicated in Fig. 10. The blade 7 2 is fixed. The blade 71 is pivoted at 108 and has an arm 109 which is actuated by the angle lever 110, the opposite end of which bears against the face of the cam 111, on the shaft 1V previously referred to. mouthpiece paper A passes first asshown in Fig. 31 over a guide roller 112, a spring supported tension roller 113, and a second guide roller 114, and thence along the top of the table in the direction of the arrow, Fig. 1.

The

At the side of this table extending parallel therewith, is a shaft 115 parallel thereto, the portion of the table supporting this strip being designated by the numeral 116. The paper A does not rest directly on the strip 116 but upon successive blocks elevated slightly above the table to facilitate application of the tools to their work. The first block (Fig. 25) is accurately spaced relatively to the longitudinal shaft 115 by means of arms 117 extending from said shaft over the table 116. These arms carry also a cover piece 118 which overlies the paper Aand which carries in turn a stop or guide 119 adjustable transversely of the table so as to determine the position of the edges of the paper. The cutter 120 is provided with pointed teeth and is fastened on the shaft 115 and actuated thereby, the cover plate 118 and the block on which the paper is held being provided with a serrated edge similar to the teeth of the cutter 120, so that the cutter and block act like the blades of a pair of shears and cut out the triangular pieces between the points. The next tool is a rubber roller 121 mounted on an arm of the shaft 115 and used for bending down the teeth over the sharp edge of a block 122 which is screwed directly upon the table 116. The paper A thence passes under a holding device so as to prevent its retraction by the tension spring after it has been advanced by the feeding device hereinafter described. This holding device is an approximately areshaped piece 123 loosely mounted on a short shaft 124 extending across the table, the areshaped piece or foot 123 being pressed backward by a slight spring 125, and beingof less radius at its rear portion than at its forward portion. Now when the paper A 138 which as the slide is reciprocated moves is carried forward, in the direction of the I arrow, the arc-shaped foot allows it to pass freely. The foot remains, however, in contact with the paper and the least backward movement of the paper causes a corresponding backward movement of the foot and a gripping of the paper between the foot 123 and the block 126 above which the foot is located.

The mouthpiece paper is advanced by a device which grips it near its end, advances it until its end enters the rolling mechanism and then releases it, the proper length being cut off by a pair of shears, and the advancing gripper being then returned to position for the next operation. The ad vancing gripper includes an oscillating eccentric or arm 127 and a supporting plate 128, the arm 127 being provided with springs 127? adapted to press the paper A against the table when the arm s swung downward by the rotation of its shaft, as shown best in Fig. 20, the mouthpiece paper A being gripped near its end as indicated in dotted lines, and the eccentric and plate being both advanced toward the rolling mechanism. Fig. 20 shows the advanced position and Fig. 24 shows the retracted position in dotted lines and an intermediate position in full lines. Fig. 30 shows how the gripper may pass between the open blades ofthe stationary shears for cutting ofi the mouthpieces. The shears and gripper are arranged beyond the end of the table 116 and upon the end of the table is a projecting guide 131 with light springs 132 (Figs. 24 and 29) holding up the end of the paper A in convenient position for cutting by the shears. The shaft 133 of the shears extends backward into a fixed bearing 134 mounted on the table and in which it can be adjusted longitudinally. The eccentric 127 is on a shaft 135 which is mounted in a bearing 136 on a slide 137 reciprocating longitudinally on the guide 160 fixedly attached to a post 146 mounted on the table X, the shaft being provided at its outer end with a crank pin backward and forward in a longitudinal slot in a member 139, which at intervals is raised and lowered to turn the shaft and grip the paper. The slide 137 is reciprocated by means of a link 140 connecting it with the vertical arm 141 of an angle lever, the other arm 142 of which rests upon a cam 143 on a shaft previously referred to and which runs from right to left under the main table X. The plate 128 is L-shaped, as shown in Fig. 30, and is fastened on the end of the slide by means of its vertical portion, while its horizontal portion projects out into the line of the table 116 along which the paper A is fed, so that the lower. blade 130 of the shears may swing below it to a position between the plate 128 and the the direction of the arrow, Fig. 32.

point of attachment of the link 140 to permit the reciprocating movement of the plate and the clamping arms between the open blades of the shears.

The slotted member 139 is raised to effect the clamping of the paper when the gripping device is retracted, and is held in raised position while the gripping 1nechanism carries the paper forward, and until the end of the paper is gripped by the rolling mechanism, whereupon the slotted member 139 is lowered to open the gripping mechanism and hold it open while it is retracted to its starting point. For effecting these movements the slotted member 139 is mounted on the top of a slide 145, which is guided in a hollow vertical post 146, and which is reciprocated by means of a lever 147 carrying a roller engaging a transverse slot in the slide 145, the lever being pivoted at 148 and provided with a roller 149 at an intermediate point of its length, which roller is in the path'of a cam 150 mounted on the continuously rotating upper shaft 1V. The arm 147 is normally drawn upward by means of a spring 156, so that the clamp is operated with a spring pressure and is positively raised by the action of the cam. By rendering this clamping mechanism ineffective the apparatus may continue to work making only cigarette tubes; as the mouthpiece paper will not be fed to the rolling mechanism the other parts of the apparatus will move without effect, the main shafts continuing to operate as before. This result is obtained by throwing the hand lever 157 in This hand lever operates a cam 158 which bears down on a roller 159 projecting laterally from the slide 145, and thus holds the spring 156 extended and holds the lever 147 beyond the influence of the cam 150. The holding of the post 145 down holds down the crank on the shaft 135 of the movable member of the clamp, and thus holds the clamp open so that it m reciprocate without effect.

For varying the length of the pieces of mouthpiece paper which are out off, the movement of the slide 137 which carries the clamping mechanism is limited adjustably. The slide travels upon a guide 160 fixed at the side of the post 146 and is advanced, as previously explained, by means of the arm 141 which is thrown forward by means of the cam 143. This arm and the slide 137 are moved backward by means of a spring 161, and the backward movement is limited by a stop 162 which is fastened adjustably upon the top of the guide 160; so that as the spring 161 pulls the slide 137 backward the latter moves until it strikes the stop 162, and the location of this stop determines the retracted point at which the gripping mechanism takes hold of the pa per. The cam 143 is designed for the maximum length, and minimum and intermediate lengths are insured by the forward adjustment of the stop. Both blades 129 and 130 of the shears are actuated. The upper blade 129 has a rearwardly projecting arm 163, the rounded end of which lies in a slotted member 164 carried on the top of a vertically moving post 165 which post carries also a sleeve 166 provided with a cam 167 at the side which bears against a roller on the end of the outer arm 168 of the lower blade 130 of the shears. The post 165 is guided through a hollow column 169 mounted on the table, and has at its lower end a roller running in a groove in a cam 166 mounted on the lower shaft 60. When the post 165 moves upward it presses the shear arm 168 inward and the arm 163 upward, so as to bring the two blades together, and this operation takes place when the gripping mechanism has carried the paper to the most advanced point. The upper blade 129 of the shears is positively lifted by means of its slotted member 164:. The lower blade 130 is pulled down by a spring 170 when released by its cam. The shaft 115 which carries tooth-cutting and bending mechanisms, is oscillated by means of the cam groove in the edge of a earn 171, Fig. 31, engaging a roller on the end of an arm 172 carried on the forward end of the shaft 115.

The rolling of the mouthpiece and its ejection into the rotating carrier, are accomplished by the mechanism illustrated chiefly in Figs. 18 to 21. The rolling is accomplished within the fixed barrel 173 open at both ends. At the rear the barrel is provided with a slot 174 through which the end of the mouthpiece paper A is inserted. At the front there is a slot 175 through which passes the plate 6% of the ejector previously described. \Vithin the fixed barrel 173 is a hollow rod 176 with a slot which in the position of rest. faces the slot 17 1 of the barrel, and within the hollow rod is a gripping rod 177 having also a slot or groove facing the slot 17 1 in the position of rest. The mouthpiece paper is thrust through the 7 slot 1741 of the barrel and through the rod 176 into the groove in the central rod 177. The latter is then given a short initial turn which grips the edge of the paper in the manner shown in Fig. 20, after which both the central rod 177 and the hollow rod 176 are rotated sufliciently to wind the mouthpiece and to carry them farther to the position shown in Fig. 20, the ejector being then in the rear of the rolled mouthpiece. The central rod 177 is then turned backward to bring its groove into register with the slots in the other parts, which movement releases the grip on the inner edge of the mouthpiece. The ejector then moves forward carrying the mouthpiece into the appropriate tube of the rotating carrier, and

returns to its retracted position, after which gear 178 which is driven by a pinion 179 ro-' tated by a gear 144 on the shaft 60. The gear 178 is fixed on the extremity of a shaft 180, andcarries a crank pin 18L connected by a rod 182 to the toothed sector 183, which is thus oscillated. The sector 183 engages a pinion 18st fixed on the shaft 185 which carries a gear 186 driving a pinion 187, which in turn drives a pinion 188 which is on the end of a rotary tube 189 which at its right hand end is connected with the hollow tube 176 of the rolling mechanism, the connection being such as to permit ready assembling and separation of the parts. The gear 186 is loose on its shaft 185, but is free to slide.

thereon and may be clutched thereto, the connection being effected by means of a feather 589 mounted on the shaft and entering a longitudinal slot in a clutch sleeve 588 engaging tenons 587 carried on the hub 586 of the gear. This connection permits the sleeve 588 to be separated from engagement with the tenons 587. The movement of the sleeve 588 in an axial direction is effected by means of a roller 190 engaging a groove which extends around the sleeve, connected to a lever 191 pivoted at 192, and having at its opposite end a roller 193 engaged in a peripheral cam groove in the cam 194.

The mouthpiece is rolled during a forward movement of thesector 183, and the hollow tube 17 (Sand its actuating tube 189 are held stationary during the return movements of the sector. The rolling tubes are locked by means of a lever 195 furnished at its upper end with a finger 196, and controlled by the cam 197 fixed on the shaft 180. The tube 189 is provided with a ring 198 fixed thereon and provided with a notch 199 adapted to receive the finger 196 of the locking lever. When the lever 195 is actuated by the high part of the cam 197 the rolling tube 189 isreleased when the low part of the cam is in position the lever is drawn forward by a spring to cause the finger 196 to enter the notch and lock the tube.

The gripping rod 177 which lies within the mouthpiece rolling tube, is extended through the tube, as shown at 204 in Fig. 19, and provided on its rear end with a disk 200 upon which is fixed a crank pin 201 carrying a roller, which lies in the path of a cam 202 upon a continuously rotating shaft 203. About the rear extension 204 of the gripping rod is coiled a spring 205 fixed at the left handend to the disk 200 which is fixed on the rear end of the rod, and connected at its opposite end to a ring 206 which is fastened by a screw to the outer tube 189. Alongside of the ring 206 is a second ring 207 connected to the central
