PACKAGING MECHANISM.

.Application led February 23, 1921. Serial No, 447,151.`

To all whom it 'may concern.'

Be it known that we, JONATHAN YPaTEizso-N and JAMES C. THoM, citizens of the United States, and residents of Brooklyn and Chiago, respectively, in the counties of Kings and Cook and States of New York and Illinois, respectively, have invented certain new and useful Improvements in Packaging Mechanism, of which the following is a specification. f

Our invention relates to machines especially adapted for packaging tobacco, such a`s granulated, line cut or cut plug tobacco, and also for packaging other commod-y ities capable of being handled in a similar way, or which it is desired to package in a similar manner.

The complete invention provides means for forming suitable containers and for filling them, and both the container forming and the filling mechanisms have novel features of value in'themselves as well as in combination.

While the invention is in many respects adapted in the specific form hereshown `to produce pouch packages of the kind described in a prior application of Jonathan Peterson, Serial No. 300,360, filed May 28, 1919, for containers and method of producing same, and to fill such containers with suitable tobacco products. To this end the invention comprises, in the present embodiment, as brieiy described, means for feeding continuous strips of pouch material, each strip having one surface coated with cementitious or adhesive material, applying additional adhesive stripes to marginal portions of one of the strips, cutting off portions of each strip, and forming the two corresponding portions of different strips successively over a plunger to produce a pouch, advancing the pouches successively to a conveyor,.depositing successive partial charges of tobacco in each pouch, pressing down each charge, and finally placing a. card or ticket in each pouch on top of its contents.

` The cementitious coating of the pouch material preferably utilized in the present machine is of such a character that two such surfaces readily adhere together to form a. composite pouch wall; but these surfaces are practically free from adhesive quallties other materials with to come in contact in when applied to any which they are likely the process of pouch formation. For instance, these surfaces will not appreciably adhere to ordinary paper surfaces, or to metal parts. The cementitious surfaces are produced upon the strips of material before utilization in the machine. It is therefore possible in a properly adapted machine, as in the present instance, `to practically do away with gumming apparatus in the machine itself, and also to avoid difficulties incident to the manipulation in the machine of glued or other adhesively coated surfaces, which readily adhere to other paper surfaces or to machine parts. The present mechanism takes full advantage of the described qualities of the cementitious coatings, both in the simplification of the machine structure, and in the acceleration of production and freedom from difficulties caused by improperly formed pouches or pieces of the material sticking to parts of the machine and other similar diiiiculties arising where ordinaly adhesive is present.

The strip of pouch material which forms the outer member of the composite pouch is desirably imprinted on its outer face with suitable identifying advertising or other subject matter, these imprints being repeated at intervals corresponding substantially to the length of individual blanks to be out from the strip; and the invention therefore provides means for maintaining the registration 'of the successive printed blank sections with the blank forming mechanism;

' novel and important features which are best understood in the following detail description of the representative embodiment showny in. the accompanying drawings. The principles of the invention arel sufficiently explained in the detail descriptiom'and persons skilled in the art will understand that muon, or CHICAGO, i

many variations may be made in details as well as in combinations and sub-combinations of parts, and we contemplate the employment of any structures that are properly within the sco-pe of the appended claims.

Fig. 11 is a section at 11-11, Fig. 10.`

The main frame comprises legs 1, parallel longitudinal members 2 connected |by cross pieces 3, other parallel longitudinal members 4, suitably connected, other parallel longitudinal members 5 suitably connected, upper parallel longitudinal members 6 connected by suitable cross members and supported at one end of the machine by uprights 7, at the other end by uprights 8, and intermediately by uprights 9. The forward section of the machine, to the left of uprights 9 in Fig. 1, comprises the mechanism for feeding the strips of pouch material and forming the pouches.

Fig. 7 shows two blanks A and C of pouch materia-l, usually paper of suitablequality and thickness successively folded and associated t0 produce pouch P. An oblong blank A is usually coated on one side with araliii and on t-he other side, visible in the gure, with suitable cementitious or adhesive material a.. Particularly this may be a rubber composition, of such a nature that when the strip of paper is coated and vrolled it will remain somewhat soft and tacky, and will retain its adhesive quality when the strip is unrolled and cut into blanks for pouch formation. A plunger B is brought against the center of blank A and the blank is folded about the plunger with the cemented surface outward, the blank being formed in the folding process with end folds b and side flaps c imprinted with suitable indicia or advertising matter c including desirably a particular portion I which is to be used for index or-registr purposes as later explained.

'This blank is olded upon the inner blank `1n substantially the same manner, that is, by

producing end tucks or folds f and side flaps g and L and all of the inward surfaces of the blank C adhere firmly to the inner blank except under the overlapped margin of flap h. To provide for securing these margins, stripes of adhesive 7c may be placed along the longitudinal margins of the outer surface of blank C" and when the blank is folded the adhesive stripes on the margins of flaps g secure the overlying margins of flap h. There is thus produced a rectangular pouch P having an open end at m and consisting at every point of at least two layers of paper with an interlining of substantially moisture-proof material, which retains its flexibility after drying. The outer surface of the package also has suitable printed matter e and desirably the poi'- tion I of this appears on the closed end (bottom) ofthe pouch. My above identified application should be referred to for further description of characteristics of the pouch and the general method of making it.

A continuous strip of blank material A (Fig. 1) is provided in the form of a roll 10, on a. shaft 11, resting in socket bearings 12 carried by brackets 13 on uprights 7 From the roll the strip A passes over a guide roll 14 and between feed rolls 15 and 16. A continuous strip of blank material C is provided iii the form of a roll 1S carried by a shaft 19 resting in socket bearings 20 supported by brackets 21 on uprights 7. After application of adhesive stripcs'l.l strip C is guided between feed rolls 24 and 25. The adhesive surfaces of the strips A and C arc so arranged that they always confront each other during the feed moven'ients of the strips.

Suitable mechanism 28 supported 0n brackets 29 is provided for applying the adhesive stripes 7c. This comprises as shown in Fig. 4, an adhesive reservoir 30 having a cover 31 slotted to accommodate two applying wheels 32 which dip into the adhesive 33 and are carried by a shaft 34 mounted in bearings in side walls of the reservoir. (,)pposed to wheels 32 is an abutment roll mounted on a shaft 39. lShafts 34 and 39 isisl may be connected to revolve together by employed for the with a handle 60. In

gears 40, 41, and shaft 39 may be positively driven in any convenientl manner or the rolls may be driven merely by contact with the strip. Strip C passes first over a guide roll 43 and then under roll 38 and in contact 72 with wheels 32, which apply a stripe of adhesive le to each outer surface margin of the Strip. The adhesive may desirably be cementitious material similar to the 'coating main inward surfaces of the strips, that is, a rubber composition kept properly fluid for application by a suitable ingredient such as benzine or other solvent. After receiving the adhesive stripes the adhesive is desirably dried somewhat by a suitable device 45, in which jets of air are supplied from perforated air tubes 46 supported by brackets 47 and supplied with air from any suitable source through pipes 48. Strip C is moved withl its outer surface margins close to the rows of air jets, which suiiiciently dry the adhesive stripes as they pass. Strip C now goes over Ia guide roll 49 to its main feed rolls 24 and 25.

The main feed rolls 15, 16 and 24, 25 are carried by housing or frame 52 located above longitudinal frame members 6. Of each pair of main feed rolls, one roll such as .roll 15 is carried by a shaft 53 mounted in fixed bearings and the other roll, 16, is carried by a shaft 54 mounted in movable bearing blocks 56 acted upon by springs 57 to bring roll 16 into driving engagement with roll 15 and the movable roll may be retracted by suitable means such as a cam 59 provided this way the feed of either strip may be quickly discontinued when desired by moving the appropriate handle. The main feed devices are positively driven in any convenient manner, in the present instance by connecting the shafts p of rolls 15 and 24 together by suitable gears,

and by connecting one of the shafts, such as shaft 53, by sprockets and a. chain 62 with a shaft 64 mounted in bearings on brackets 65, secu-red to frame members 6.

Each blank strip is now conducted through suitable secondary or auxiliary feeding mechanism 68 and through suitable guides 69 to cutting ofi' and blank positioning devices at 70, Fig. 1. The auxiliary feed and cutting off mechanisms for each strip are substantially identical, and the guide structures are substantially identical except for certain -features later mentioned. The secondary feed mechanism 68 for each strip comprises (Figs. 1 and 3) a main roll 72 having fianges 73 to guide the strip, and a small co-operating roll 75. The main roll is carried by a shaft 76 and strip-engaging tread portion 78 and a partcircular portion 79 of smaller radius. The coloperating roll 75 has a cylindricalsurface and is carried by arms 81 pivoted at 83 has a part-circular and provided with a gularl 72. y

o-operating stops 86 and 87 are provided to limit the inward movement of roll 75. Both of the large auxiliary feed rolls are positively driven, for example by sprockets and a chain -89 connecting one of the roll shafts 76 with shaft 64 previously mentioned, and by gears, sprockets and a chain 91 connecting the two shafts 76 together. The circumferential length of enlarged roll tread portions 78 correspond to the desired length of the blank. Evidently therefore at each rotation of one of the large rolls a feed engagement with the corresponding strip is effected by that roll and its co-operating .-roll 75, and the strip is advanced one blank-length. The main febed rolls are usually driven at such a rate that some slack is maintained in the strips between them and the auxiliary feed mechanism, and at each auxiliary feed act-ion some or all of this slack is Ataken up. Either auxiliary feed maybe discontinued by raising its counterweight 84, and when desired, cont-rolling devices convenient to the operator may be provided for this purpose. Similarly,connections may lead from cams 59 of the mainfeed devices to control levers at points convenient #to the operator, who is usually placed at the near side of the machine as viewed in Fig. 1, near the vertically moving parallel blank strips.

fter passing the auxiliary feed mechanism each blank strip passes through guides 69, each comprising two parallel, spaced walls consisting of t in strips 94 arranged in edgewise relation to the blank strip at each side thereof, thedifferent strips or links being connected by transverse rods 95. The upper ends of the guides may be supported on frame members arrangement permits the strips to be observed during their travel, and especially permits the printed surface of strip C to bel observed. The lower ends 96 of the lower strips 94 lare reduced in width and located loosely within the flared upper ends 98 of guides 100 which direct thc strips to thc cutting olf mechanism, Figs. 1, 2 and 5.

This mechanism 102 carrying fixed cutter plates 103 each provided With a; slot 105 having a cutting edge 107. A movable cutting plate 109 is slidably mounted on each fixed -cutting plate and is suitably guided, for instance, by gibs 110. Each movable cutting plate has a slot 112 provided with a cutting edge 114. Strip guides 100 are connected to lugs 116 secured to the movable cutter plates, and their narrow lower ends direct the strips to slots 105 and 112. Main plate 102 is apertured to provide guides 120, consisting of

members

121 and 122, to conduct the severed blanks to lower positioning guides 125. Plate 102 comprises a main plateA 6. This openwork guide Y provides bearings for shafts 127 and 128, each of which has an arm 129 connected by a link 131 to a slotted lug 133 on one of thel movable cutter plates. The shafts are connected together by segment gears 136. Shaft 127 also has an aim 138 connected to any suitable driving device. In the present instance the connection is in the form of a rod passing through a guide hole in the upper end of an upright 142, and is provided with an adjustable collar 144 and a spring 145 compressed between the collar and the upright to retract the rod and the cutting mechanism. The rod may be actuated in any suitable way so that it is reciprocated at intervals corresponding to` feed of the individual pouch blanks and the operating mechanism may desirably be so arranged that the operator may at any time discontinue the cutting operation. For this purpose a lever 148 is provided, fulcrumed at 149 on a bracket 150 and engaging between. collars 152 o-n rod 140. By moving the lever the operator may compress spring and hold the cutting mechanism out of action, or may cut off blanks when the machine is not running. The rod may be driven by a cam or other suitable connection with main drive shaft 154, later referred to, or other driving arrangements for the cutting mechanism may be provided.

Below the cutting mechanism, the `two blank positioning channels 125 are provided, each comprising parallel plates and 161, having their upper ends. 162 divergently flared to receive blanks from the lower ends of guides 120; and flared portions 162 may also consist of spaced members 164 of reduced width, co-operating with slots 166 in

guide members

121 and 122 to permit ample relative vertical movement of the guides. The positioning channels 125 are. carried by transverse angle bars 170 supported on longitudinal frame members 4. These anglebars also support a short forward section 172 of a longitudinal pouch forming channel, this short section consisting of a top plate 174, bottom plate 175 and yside plates 176. Positioning channel 125 for blanks A is located at the entrance of this forming channel section and positioning channel 125 for blanks C is atthe rear end of the channel.

Plates

160 and 161 have apertures in line with the folding channel to permit passage of the forming plunger and associated blanks. The lower ends of

plates

160 and 161 are provided with vertical slots 182 and in these slots are arranged blank-supporting projections 184 formed on a plate 186 carried by a lower supporting and blank adjusting member 188. Plates 161 are provided with blank engaging devices 190, also located in slots 182, having angular faces 191, which hold the respective blanks near one wall 160 of their positioning channels. Members are connected to cross pieces 193, molvably secured to plates 161 by pins 195 and slots 197.

'Adjusting member 188, and main plate 102 of thecutting mechanism are supported and connected together for simultaneous ver` tical adjustment as follows: Each of these members has at each side of the machine a short sleeve 200 accommodating a rotatable sleeve nut 201 which may be rotated by means of holes 203 bored in its flanged end 205, and secured in adjusted position by a set screw 206. At each side of the machine a vertical screw shaft 208 is arranged to pass through the sleeve nuts at that side of plate 102 and member 188. Each of these screw shafts is threaded at each end, the screw threads at one end being right-handed and at the other end left-handed, and the nuts being threaded correspondingly. Each screw shaft carries a spiral gear 210 held against end movement by the jaws 211 of supporting yokes 212 secured to longitudinal frame members 4, the yoke jaws being also apertured to provide bearings for the screw shaft above and below the spiral gear.

'Transversely arranged in bearings in lugs 214 secured to frame members 4 is a shaft 216, provided with s iral gears 218, one engaging with each o. the spiral gears 210. At the front of the`machine, convenient to the operator, shaft 216 is provided with a hand wheel 220.

The positions of top plate 102 carrying the cutting mechanism, and of cross piece 188 carrying the stop pla-te to support the pouch blanks in front of the plunger, may be initially adjusted by rotating sleeve nuts 201 and securing them by their set screws 206. The positions of both of these members may then be quickly adjusted simultaneously from time to time as may be required in the operation of the machine by rotating the hand wheel. lVhen this is turned in oneI direction the. platos are brought nearer together', with the sana` amount of movement in relation to the line of plunger travel; and when the wheel is turned in the other direction the plates are moved apart in a similar way. There is thus provided mea-ns for quickly adjusting the point at which blanks are cut from the advancing strips, in accordance with any variation in the rate of strip feed or variations in the spacing of the printed matter occurring repetitiously on the outer surface of strip C, or for other reasons. At the same time, the position of stop plate 186 is correspondingly altered, so that the cut-off blanks are properly centered in front of the advancing plunger.

It is desirable to provide especially convenient means to enable the operator to.

properly adjust the strip-feeding and blankhandling mechanism. Such means is exem- A plied in the present case as follows: At

a suitable point on one of the blank strip guides, and most dcsirably at the rear of the guide for blank strip C, a suitable index device is arranged and conveniently this is in the form of a plate 225 (Fig. 2). secured to guide members 94 and provided with an aperture 226 substantially corresponding with the dimensions ofthe special index subject-matter I printed on the adjacent faceof the strip, as explainedin connection with Fig. 7. The aperture in the plate provides, practically, a window through which the index matter may be observed and' the index is positioned so that when the feed mechanism is operating properly, the index matter I is centered inthe window at the end of each feed movement. If for -any reason the index subject matter commences to get out of registry with the. window, the feed may be adjusted to restore registration, by manipulating leve-rs to control the main strip feed, or by manipulating the levers which carry counterweights 84 to regulate the secondary or intermittent strip` feed. In this waythe successive blanks will be brought back to the proper center relation to the index window.

The blank cutting and positioning mechanism is also desirably connected with a suitable indicating device exemplified in the present case by a pointer 228, pivoted at 229 and connected' to main plate 102 of the cut-- ting mechanism by a link 230.- The free end of the pointer moves over a calibrated sector`282. Normally the operator will move hand wheel'220 to maintain the pointe-1' at the center of its scale, this corresponding to the properly registered position of the index subject matter I, as shown in Fig. 2. If, however, the advancing strip gets out of registry the hand wheel may be properly moved to adjust the blank cut-oft' mecha.- nism in either direction in accordance with retardation or acceleration of the strip movement, and under all conditions the blanks which are cut olf are properly centered in respect to the center line of the pouch forming` channel. Any variation in length of the blank cut from one strip isaccompanied by h a corresponding variation in length of the other lblank so that the blanks are always of thc same length and properly formed pouches will be produced regardless of moderate variations in the length of the blank.

The pointer affords an easy means for observing the` position of the blank handling mechanism and also for noting the amount of adj ustment that is effected in either direction. Either of the described devices, that is the registration index device or the adjustment indicating pointer, or their equivalents, may be used in some cases without the other.

It will be understood that the index windowr shows theposition vof the advancing strip, by observation of a definite part, of

each prmted'strip behind the window; and l to norma-l ork tion.

kThe pouchy forming plunger, consisting substantially of a long bar 234 of rectangular cross section, is arranged to reciprocate through the short forming channel 1.72 and a long in line with the short channel and withits forward end just to the rear of the rear blank positioning channel 125. The long forming channel comprises side pla-tes 237, a bottom plate 238 and a top plate 239, and is supported by suitable cross pieces 240 resting on longitudinal frame members 4. At the `front end of the short forming channel a blank end folding block 242 is arranged at each side, the front ends of these blocks serving to` fold in the end portions of blanks A against the sides o-f the plunger, producing end folds (Fig. 7). Spaces between the upper and lower surfaces of these blocks and the top and bottom plates respectively, accommodate projecting side flaps c and d of the blank. The rear ends of blocks 242 are lprovided with upwardly beveled faces 243 and spaced slightly to the rear of these are folding blocks 245 located on bottom plate 1.75, these blocks lhaving angular faces 24.6 which fold side flaps cup aga-inst the sides of the plunger in co-operation with the bev-k eled faces 243of blocks 242. To the rear of blocks 245 other folding blocks 248 are arranged at the sides of the channel, and these ave angular faces 249 co-ope'rating with the rearward faces 251 of blocks 245 to fold side flaps d down against the sides of the plunger andover the margins of flaps c. The plunger with `its advancing end covered by the formed blank A,thcnengages the center of blank C and moves the combined blanks through the long forming channel, in which folding blocks 253, 254 and 255 are located, and which perform substantially the same functions with respect to the outer blank as were performed upon the inner blank in the short channel. VThe plunger is supported and guided in its movement by the top and bottom Walls of the channels and by the inner faces of the folding blocks., and may be and the operator may then take the strip feed.y

i the pointer will incidentally be brought back approximately central posil f forming channel 236 arranged also additionally supported and guided by other suitable means such as aguide member 257 through which the forward end of the plunger moves as shown in Fig. 1. As the pouch covered plunger advances through the long channel the plunger may be additionally supported by a roller 258 acting through an aperture in bottom plate 238 and. provided with a shaft 259 carried in bearings 260: and after the outer blank is completely folded, its sides may be pressed against the plunger by rollers 263 located at the sides of the channel; and the shafts 264 of these rollers are desirably carried by movable bearing members 265, adjusted by screws 265 provided with lock nuts 266 so that the pressure of the rollers on the pouch sides may be regulated.

The plunger yis reciprocated by suit-able means, such as multiplying gearing, comprising a large gear 269 journalled at 270 in frame members 4 and engaging rack teeth 27 2 on the under face ot the plunger. Gear 269 is provided with a. pinion 272 and this is engaged by a large segment gear 275 journalled at 276 on frame members 4. The segment gear has a. crank pin 278 connected by a pitman 280 to a crank arm 282 on shaft 154 previously mentioned, which is mounted in bearings in brackets 284 resting on frame members 4. The connection ot pitman 280 with crank 282 may be an adjustable connection of any suitable form to vary the travel of the segment gear and so to adjust the stroke of the plunger.

At the end of each advance movement of the plunger it delivers its pouch to a. pouch holder 286 which is one of a series of regularly spaced holders carried by a conveyor 288, intermittently driven to move a succession of pouches for the lilling operations. The conveyor comprises a pair of parallel chains 290, to opposite links of which are connected plates 291, and to-these plates are connected the pouch holders, each of which comprises a pair ot plates 293 spaced apart to receive the pouch and shoes 295 extending Iorward and rearward from the plates in the direction of movement of the conveyor and substantially Hush with the open bottom of the holder, the ends of these shoeS being outwardly curved as at 296. As the pouch-covered end of the plunger emerges from the long forming channel, it is in line with one of the pouch holders carried by ascending stretches of the conveyor chains; and the open bottom of the holder is confronted by an abut-ment consisting of a rubber block 297 carried by a stationary 'frame piece 299. c

At each advanced movement of the plunger'it encounters successively inner and outer blanks positioned in the vertical channels. and carries these blanks forward and folds them successively. and the adhesive inner surfaces of the blanks are pressed to.- gether and marginal portions ot the outer blank carrying the adhesive stripes 7c are suitably pressed together, and at the end of its advance movement the pouch emerges from the long channel and passes into a properly positioned holder and the bottom ot the pouch is pressed by the plunger against. the abutment block. The plunger is then withdrawn and the pouch may be rctained in the holder by frictional engagement with its walls; but other or additional means and desirably provided for dis# charging the pouch, consisting in the present case of one or more air passages 301 bored longitudinally in the forward end of the plunger and connected to a long air passage 303 terminating in a port 304 in the upper surface of the plunger (Fig. 5). The upper surface of the plunger at the left of the short forming channel is closely en gaged by a block 306 having in its engaging face an air channel 307 in line with port 304. Air is supplied to the channel under pressure from any suitable source by a pipe 309.

At about the time the advancing end of the plunger positions the pouch in the holder, port 304 comes into communication with air channel 307 and air is thus ejected into the pouch through apertures 301, and the pouch 'f is practically blown off the end of the plunger as the latter retreats. The de scribed cycle ofoperations is repeated to supply to each successive holder of the conveyor.

The conveyor chains run over pairs of sprockets carried by shafts 311, 312 and 313, supported in suitable bearings on different trame members. bearing blocks 314 for shafts 312 being ydesirably mounted in guides 316 at therear end of the frame and provided with adjusting screws 318 and nuts 319 for properly tensioning the conveyor. One of t-he conveyor shafts such as shaft 311 is intermittently driven from shaft 154 previously mentioned, by any suitable intermittent driving mechanism, such as the Geneva wheel and stud carried by

shafts

311 and 154, respectively. Shaft 154 may be the main drive shaft of the entire machine, and for that purpose is provided with a driving pulley 322'. The upper stretches ot the conveyor chains are desirably guided and supported by rails 324 carried by frame cross members 326, these rails engaging the chain blocks between the side links and the lower stretches of the chains may be similarly supported and guided by rails 328. Between rails 324 a longitudinal plate 330 is supported which underlies the open bottoms of holders 286 throughout the extent of the different filling and pressing positions, to su port the pouches within the holders.

etween frame uprights 8 and 9, a vertically movable table 332 is located just above the upper ends 0f `the advancing roW of pouch holders. This table is carried by vertical rods 333 passing through sleeves 335 rest-ing on frame cross members 337; and the lower ends of the pairs of rods are connected by cross pieces 338. Each cross piece is provided on the bott-om with a slotted lug 340 carrying a rotatable cam r0ller` carries a row of feed chutes 355, four in the present instance, and each 'chute has a spout 356 of a size approximating the interior contour of the open end of the pouch, this spout the-plate. Above and somewhat to one side of each charging chute is a tobacco hopper 358, these being supported by a longitudinal frame member 359. A shaft 361 supported in bearings in frame uprights 8 and 9, runs between the hoppers and chutes and carries charge transfer wheels 363, one foreach hopper and chute. Each wheel is arranged so that an upper surface runs close to the discharge opening 365 of a hopper, and a lower surface is adjacent to the upper end of the corresponding chute. In the surface of each transfer wheel is a series of equally spaced tobacco pockets 367. Shaft 361is driven by a bevel gear 369 at its forward end,v engaging a bevel pinion 371 on a transverse shaft 373. which is connected by sprockets 375 and a chain 376 to main drive shaft 154, or another suitable driving member. A charge cont-rolling roll 378 is arranged to run close to vor engage the periphery of each transfer Wheel substantially at the top, thereof, and these rolls are accommodatedwby suitable formation of hopper walls 380. Rolls 378 are carried on a

shaft

38,2 mounted in bearings lin frame uprights 8 and 9, and are driven in the same direction as shaft 361, so that the surfaces of the charge controlling rolls in engagement With the transfer wheels move in a reverse direction, that is, ,back toward the hoppers, to move back any surplus amount of tobacco and prevent the transfer of an excessive amount of tobacco in any one charge. The shaft 382 is driven by sprockets and a chain 384 from a longitudinal overhead shaft 386 carried in bearings 388, and itself driven from shaft 64 by bevel gears 390. The shaft last mentioned is driven by sprockets and a chain 392 from main drive shaft 154.

In each tobacco ho-pper a stirring or agitating device is provided to insure a proper movement of the tobacco yand filling of the transfer pockets. Each of these devices consists in the presentinst-ance of a stirring assine' throu l1 an a erture in or pushing blade 394, the free end of which is arranged to slide against the inclined wall 396 of the hopper, and carried by an arm 398 pivoted to a crank'400 on a longitudinal shaft 402, mounted in bearings 404. At one end this shaft has another crank arm 406 connecte-d by a pitma-n 408 with a crank 410 on the adjacent end of overhead shaft 386. In this way the stirrer shaft 402 is continuously oscillated and the agitator blades are moved up and down to push the contents of the hoppers toward the pockets.

To the rear of each filling device is aV charge compressing device comprising a plunger 4144 movably arranged in guides 416 carried bytable 332 and passing through' an aperture in the table,

the plunger being formed to? fit with suitable clearance within the pouch.` Each'plunger is connected to a link 418, and each link is connected adjustf ably to a crank arm 420, so that by adj ust` ing the connection toward and from the crank rotation center the stroke of the corresponding p-lunger may be varied. The driving cranks 420 are arranged 1n pairs on short shafts 422 carried in bearings 424 on brackets depending from frame members 6, and each of these crank shafts is driven by sprockets and a chain 426 from overhead shaft 386.

While the machine can easily be arranged so lthat each pouch is entirely filled by one suitable filling device, for instance by making the transfer pockets of sufficient size to carry an entire charge, o-r rotating a single transfer wheel at-such speed that a plurality of small charges will be delivered to the pouch in one conveyor position, and in such cases a single compresser would sutliec, it is preferred, as herein shown, to fill each pouch with a plurality of relatively small charges and to compress each charge separately. Consequently the first compressing the ends of plunger must descend relatively near to thel bottom of the pouch, and the second will not descend so far, and so on to the rear plunger, which .descends only a short distance into the pouch. The adjustment of the links 418 above described is provided to enable the strokes of the compression plungers to be conveniently varied for the pun pose stated.

It is desirable. in some cases, as here shown, to arrange the last charging device in theiseries so that a smaller charge may be inserted in the 4pouch than at previous positio-ns, or so that the charge supplied here may be varied as may be necessary or de` sirable. For thispurpose instead of a single transfer pocket at each point on the rear transfer wheel, the periphery o-f this wheel is desirably provided with equally spaced series of small pockets 428, for instance, three of these pockets in a row, with these rows equally spaced about the wheel perimeter. A part of the open discharge end of the corresponding hopper may be blocked olf by inserting a suitable plate, or in other convenient ways tobacco may be prevented from entering any one or more of the transfer pockets of cach series and in this way the amount of the last charge may be readily varied.

It is desirable in many cases tov insert in each pouch on top of the contents a card or ticket. For this purpose avertical holder 430 for a stack of cards or labels L is supported on table 332 rearward of the last compression plunger. A slide 432 moves under the card stack and the upper face of this slide is provided with two

card engaging shoulders

434 and 436. rlhe slide has lateral flanges 433 cri-operating with guide members 440 at opposite sides of the slide and the upper surfaces of these guide members pro-vide supports 442 for the ends of the cards in intermediate positions during retreat of the slide. 'lhc slide is operated by a bell crank 444 fulcrumed at 445 on the rear wall of the card holder. Short arm 447 of the bell crank is connected by a link 449 to a stationary bracket 451; and the long arm 453 of the bell crank is connected lby a pin and slot connection 455 to the outward end of the slide. An adjustable stop may also be provided in the form of a screw 457 carried by bell crank arm 453, to limit advance movement of the slide. At each upward movement of table 332, the bell crank g acts just after the adjacent compression plunger has been Withdrawn, and a filled pouch has been brought into position under the plunger, to advance a card and drop 1n through the table aperture into the pouch; and at the same time the rearmost shoulder 436 of the slide engages the under card of the stack and moves it to an intermediate position where it rests onguide blocks 442; in the descending movement of the plate the slide is retracted and the rearmost shoulder is ready to engage another card and feed it from the stack While the foremost shoulder 434 is ready to engage the intermediately positioned card and move it forward for deposit in the pouch at the next upward movement of the' table, and so on.

rllie vertical center axis of the filling spouis 356 and plungcrs 414 are spaced equally apart so that equal movements of lho pouch conveyor from the liist filling position move a pouch successively to the ncxt compressing position, then to the next filling position, and so on, each pouch thus occupying eight active positions in the filling mechanism.

Before the conveyor commences cach movement table 332 is raised, retracting the filling spouts from the pouches. The conveyor then shifts the pouches, table 332 descends, inserting each filling spout in a pouch opening; a partial charge is deposited in each pouch by the charging lneiihanism and at the same time the charge is compressed in each pressing position by one of the plungers. The manner in which the cards are inserted has been suiiciently dcscribed. The filled pouches may be delivered to suitable closing mechanism, or may be removed by hand and disposed of in any desired way.

We have described mcchan'isi'n for associating two pieces of pouch material to form each of the pouches; but evidently by obvious omissions and din'iensional changes, or other simple changes, the mechanism may be adapted to form pouches which consist of a single piece of blank of suitable material.

It will bc understood from the previous description that the complete invention comprises, among other important features, means for autoniatically forming pouches of the general character described, and means for automatically filling them. It also comprises means for feeding continuous strips of pouch material, cutting blanks from the strips, and associating the blanks to form composite pouches. It also comprises strip feed controlling and adjusting mechanism. It also comprises, as an important feature, means for properly controlling the supply of a continuous strip of pouch material having a repetitions imprint, and controlling the registration of this strip in relation to pouch forming mechanism, and also for controlling and regulating the positioning of individual printed blanks cut from the continuous strip. It also comprises new and improved means for transferring automatically fo-rmed pouches from the forming mechanism to conveying and filling mechanism. It also comprises means for supplying successive charges to each of a succession of pouches and properly compressing each charge. It also comprises means for inserting a card in each pouch, this means being properly coordinated with the filling mechanism.

Evidently also it includes numerous important and valuable details of construction, combinations and sub-combinations of parts, in addition to the more important features, some of which are particularly mentioned just above.
