Application .filed November To-aZZw/zom it may concern:

Be itknown that we,,AnoLrH 7C. VAN SLUYS and Wm'rnnor LPERR'Y, citizens of the United States, andresidents of Nashua, in the county of Hillsborough and State of New llampshi're have invented an Improves ment in Packaging Machinesi of which the following description, in connection with the accompanying drawings,-

a specification, like characters on thexdra wings representing like parts. l

Thisinvention relates to packaging machines and aims toprovide a novel and improved machinefor winding. one or more, usually several sheets of material such as waxed paper onto a suitable coresuch as a cardboard tube. and for applying a wrapper about thesheets and the core. The 111? vention will be'best understood by reference to the following description. .Whentaken in connection with the accompanying drawings of one specific embodiment thereof, while its scope will be more particularly pointed out in the appended: claims.

.in elevation of one side of the rotating mechanism on an enlarged scale on line 9-9 of Fig. 1 and r i Fig. 10 is a vertical'sectional view of one side of the tucking mechanism on an enlarged scale on line 10-1O of Fig. 1.

Referring to the drawings and to the embodiment of the invention which is selected for. enen'iplitication there is shown a packaging machine having a suitable framework for supporting the various mechanisms, the same comprising two main frames 12 best shown in F igs. 1 and 2, and two auxiliary side frames 14.

The waxed paper feed will now be described, reference being had to Fig. 8. An operator places the sheets in successive piles on a table 16 suitably supported on the fran'lework as by the auxiliary side frames 1 1 (see Fig. 1) and. a tie piece '18 which is secured at its ends to the main frames 12. Thetable is provided with lateral guides 20 ,(see Fig. 8) between which the sheets are placed and by which the successive piles are guided toward their destination by the mechanism now to be described.

Stillreferring to Fig. 8, the table is provided with a pair of longitudinal slots 22 to receive pairs of pushers 2% by which the successive piles are progressed along the table. In the present example these pushers are lugs or dogs pivoted at suitable intervals onchains 26 whichpass over and are driven by pairs of sprocket wheels 28 and 30 (see F ig. 1). The sprocket wheels 28 are secured to a shaft 32 which is journalled in bearings presented by the auxiliary frames 14;, while the sprocket wheels 30 are secured to a shaft 34 which is journalled in bearings presented by the main frames 12.

The mechanism for feeding the hollow cores will nowbe' described, reference being had at first to Fig. 2. Suitably supported on the main frames 12 is a hopper 36 having two ends 38 and two sides 10. the latter converging downwardly toward an outlet presented by a vertical raceway 42 which is of the proper dimensions for the reception of the tubes in vertical series as they pass from the hopper. It is found that the feeding of tubes to the raceway is accomplished most satisfactorily by agitating the tubes in the hopper, as by providing the sides with hinged portions 14 whieh'are caused to move in and out in alternation as by cams 46 secured to shafts 48, the latter being mounted in appropriate bearings presented by horizontal bars 50.

Referring now to Fig. their cams are driven in unison by suitable mechanism, herein sprocket wheels 52 se cured to the respective shafts and connected by a chain Referring 'now to Fig. 5, escape of the tubes from the raceway is controlled by a raceway cut-off which, in the presentexample, is a pair of segments 56 presenting openings 58 'whichare of substantially the same dimensions horizontally the raceway, and when brought into registration therewith afford a pocket, the depth of which is just alittle more than suilicient to receive one tube. A bottom for this pocket is afiorded by a pair of stops 60 directly beneath the vertical raceway 12, said stops being conveniently formed as inwardly directed flanges on webs 62 of a pair of'br'ackets 6 1 (see Fig. 4') secured to a rod 66 whichextends transversely of the machine and terminates at opposite ends in the main side frames 12, as will be evident from a comparison of Figs. el and 5. The brackets er present channels affording as'econd raceway 68 adapted 'to receive the tubes when the cut-off segments 56 swung to the left (Fig. 5) to carry the openings 58 out of registration with the raceway 42 and into registration with the raceway 68. Thus it is evident that with eachcomplete cycle of the cut-off segments, the lowermost tube in the raceway 12 will be allowed to drop into the pocket which is then carried laterally to deliver said tube to the 'ra ceway 68, while in the meantime the segments 56 block the lower end of the raceway e12 and prevent 'the escape of the neat succeeding tube,

The cutoff segmentsbG are herein conveniently formed as integral parts of two arms '70, best shown in Fig. at, secured to a rock-shaft 72 which is mounted in suitable bearings presented by the main side frames 12. A short arm Tet, also secured to the rock shaft and'shown at the right-hand side of Fig. 1 as well as at the right-hand side of'Fig. 5, is connected by a link TGtoa cam lever 78 which is mounted on the shaft 80. A cam-roll 82 carried by the lever (see Fig. 5) cooperates with a cam 8% against which it is held by a spring 86. The cam is secured to the shaft 34 which is mounted in turn on suitable bearings presented by the side frames 12. shaft is rotated, the cam, acting through the lever 78, link 76 and arms 7% and 70,

1, the shafts andlVhen therefore, the

oscillates the segments 56 in properly timed relationship with the other cooperating parts of the machine. Incidently it may be noted that the brackets 64 (see Fig. 5) are supported not only by the cross rod 66, but also by the rock-shaft 72 on which they rest.

The winding or coiling mechanism will now be described, reference being had at first to Fig. 5. \Vhen the tube gravitates through the second raceway, 'it' is received upon a segmental movable receptacle 90, which, at the moment, is disposed in the generally horizontal'position represented in dotted lines in Fig. This receptacle is then swung upward into the position represented 'in full lines in Fig. '5, wherein it cooperates with an opposite fixed receptacle 92 of similar character, which is supported by the cross-rod 66. These two segmental receptacles together-present a chamber into which the tube is brought preparatory to the assembling therewith of the pile of waxed paper which is to be wound about the tube in a manner presently to be described. After the winding operation is completed, including the application of the wrapper, the movable receptacle is swung fron'i'the position shown in full-lines of Fig. 5 to the lowermost position shown in dotted lines therein, thereby causing the package to be discharged therefrom as will appear more fully hereinafter.

The oscillationof'the receptacleQO herein is conveniently accomplished by 'niou'nting the latter on a rock shaft94, which as best shown in Fig. 1, issupported in bearings presented by brackets 96 which'are secured to a cross- .rod 98, the latter in turn being supported by the side frames 12. These brackets (see Fig. herein conveniently 'aiford one side or guidew'ay of a third raceway 100, the other side of which is presented by a pair of brackets 102 which are secured to and depend from the brackets (341 respectively. lVhen therefore, the receptacle '90' swings in a downward direction to the lowermost position represented in dotted lines in Fig. 5, the package is allowed to descend the third raceway 100.

The oscillation of the receptacle 90 is accomplished 'in this instance by a link 101 connecting said receptacle to an arm 106. The arm 106 is secured to a sleeve 108 which, as best shown in Fig. 4-, is mounted to turn loosely on a shaft 110, and to the other end of this sleeve is secured a second arm 112 carrying a cam roll 114 which cooperates with'a cam 116, the latter being secured to a shaft 118 mou'hted'in bearings presented by the side frames 12. The outline cam 116 is'such as to give the receptacle 90 a properly timed movement with relation to the other parts of the machine. The cam-roll is caused to follow the cam by the use of a IUD ceived-.I The slots 216 and 222 are-so related that sliding movement of 'the cam toward the right from the position shown in Fig. 9 is, at first, accomplished by movement: of the plunger and the gripper in unison and, when the gripper brings up against the paper on the tube, the spring is adapt-v ed to yield and, while the plunger con-- tinues its positivemovement under the influence of the cam, the further movement of the gripper is yielding. Hence, it follows that the sheets are gripped by spring pressure, thus enabling a considerable difference in thickness to be accommodated and ensuring a firm engagement of the gripper with the sheets.

Reciprocation of the cam is accomplished by securing the same to a rod 22-1 which slides axially in the hollow shaft 12%, but. is held against turning movement with relation thereto by the engagen'ient of the latter in turn with the hollow shaft and. the plug which it carries. The outer end of the rod 22 carries a collar 226 whichpresents an annular groove 228 for the reception of a yoke 230 having trunnions 232 pivoted in the forked end of a lever 23 1-.

Referring now to Fig. 6, the lever 23-. has its fulcrum at 236 on the lever 202 and hencepartakes of the swinging movements of the latter under the influence of the cam 208. However, the lever 231i; is given a swinging movement with relation to the lever 202 by theuse of a cam-roll 238 carried by the lever 234 and cooperating with a cam 2&0. It should be observed that the two cam paths S and 24-0 are very similar, in fact, they are-so related that the hollow shaft 124. and the rod 224-, for the most part. move in unison, but the cam-paths differ to the extent that, when the plug has entered to its fullestextent into the tube, it then remains stationary while the rod 224, carrying the cam2l4, moves inan outward direction and thereby causes the gripper to move radially into engagen'ient with the papeer to grip the latter against the tube. The rod 22th then remains stationary to cause the paper to remain within the grasp of the gripper during the rotationof the tube.

After the winding operation has been completed, as will appear more fully hereinafter, the plugs are withdrawn in opposite outward directions. No attempt, however, is made to retract the gripper in a radial outward direction at this time, butthe axial movement of the plug carrying the gripper therewith is relied upon to slide the gripper lengthwise out of engagement with the. paper on the tube. However, it is necessary that, preparatory to theintroduction of the plug into the next tube, the gripper shall resume its initial, radially outward position, and to this end we have provided two cams 242, one for each of the grippers, which are mounted infixed positionon the frame of the machine, and, when the plugs are retracted to the positions shown inaFig. 6, the shanks, of the grippers engage-these cams and restore the grippers totheir initial positions.

Inthe present example, each of the 001- lars 226 (see. the rightrhand side of Fig. 9) is mounted to slide axially on a stud 24A carried. by the .outerend ofthe rod 224-, and encirclingthis studis a spring 24-6 interposed between. the collar and an abutmentv conveniently in the form of a nut 2 t8 threaded onto the, outer end of the stud. This spring is auxiliary to the spring 218, which, it1will be remembered, causes the gripper to engage the paper with yielding pressure. When, in the operation. of the gripper, the cam 214 has forced the same as far as possible against the paper through the.interventioirof thespring 218, the cam 21% will remain stationary and the spring 21-6 will yieldand allow the collar 226 to. movetoward the right under. the influence of its cam 240.

The wrapper feeding mechanism will next be described, reference being had at. first to Fig.1. A web of paper in the form of a roll- 250 is supported by a shaft 252 in bearings 25st presented by the side frames 12... The web of paper is led from the rollover suitable arranged tensionrolls 256 and 258 (see Fig. 5) and between a pair of cooperating feed rolls 260 and'262, either or both of which may be made yield ing, as by being covered with rubber. An intermittent rotati've movement in one direction (clockwisein Fig. 5) is imparted to the lower roll 262. as by theuse of a pawl and ratchet mechanism shown in end elevation in Fig. 7 and in plan at the right-- hand side of Fig.-

The rollv 260 is secured to a shaft"26'at to which is also secured a single-toothed .ratchet 266 which cooperates with a spring-pressed. pawl 26S pivoted on a pawlcarrier, herein'an arm 270 on a sleeve 272 which is loosely mounted on the shaft 264 and is provided with a pinion 274. which, as shown in Fig. 5, meshes with a segmental gear 2T6'carried by a vibrating iii-111278. This arm is secured to a shaft 280 to which is also secured .an arm 282 carrying a cam-roll 284: which is held in engagement with a cam 286' by a spring 288. The cam is securedto the shaft 3% hereinbefore described.

lVhen therefore, the cam rotates, an up and down movementv is imparted to the segmental gear. The parts are so proportioned that one stroke of the segmental gear in an upward direction causes one full rotation of thepinion 274 and consequently one full rotation .of the pawl carrier and pawl, thereby causing .or tending to cause an advance of the web of paper a linear disdirection.

tance equal to the circumference of the lower feed roll 2G0. Downward movement of the segn'iental. gear rotates the pinion 274 in the reverse direction and causes the pawl to travel idly around theratchot andto snap into place behind the single tooth thereon in readiness for the next upward movement which forms the wrapper; No, matter how accurate the feeding mechanism maybe, the slightest error will gradually accumulate and in time would result in the stoppage of the web in an incorrect position witl'r relation to the cutting IDGClltLDlSHldiLt-Cl' to be described. To avoid this diiiiculty, we have provided meansto enable the operator to vary thev amountof feedingmovement from time to time during the operation-of the machine. Referring to Fig: 52, the upper feed roll is-so mounted as to be capable of being raised and'lowered outof and into contact witlrthe lower feed roll, it being secured to a shaft290 which is journalled in bearingblocks 292 mounted to slide vertically inlguides 294C presented by the side frames 12. 'To" these bearing blocks, we have pirotedshort arms in the nature of'cams 296 as by a shaft 298'to which-both cams are secured, said shaft being mounted in the'bearing blocks asbest shown in plan in. Fig. To this rock shaft, isalso secured an arni 300,'which, as best shown in Fig. 2, carries an adjusting screw 302 which bears against agfiat spring 304: carried by the arm 300 and pre-.

senting a wiper 306 adapted for engagement with a cam hen therefore, during the rotation of the lower feed roll, the lobe on the cam engages the wiper and lifts the arm 300, engagement of the cams 296 with the top of th'eside frames 12 presents a fulcrum point about which the cams rock in an HPWEUTl direction, thereby lifting the rock shaft 298, bearing blocks-292 and upper feed roll 262. The-amount which the feed roll is thus lifted may be varied by'turning the adjusting screw 302 in the proper The web of paper, after'passing between the feed rolls, descends an inclined platen 310 ,(see Fig. 7), thelatter*extendingto a point adjacent to the roll, which is held between and rotated by the hereinbefore described plugs. This platen terminates at 308 secured to the shaft a suflicicntdistance above the table 16to permit the )assage of the pile of waxed paper sheets beneath the platen tothe proper position to be engaged by the grippers carried by the plugs. The platen is suitably secured to a crosswise tie-piece 312 which. secured,as-by cap screws 314 to the side frames 12. This tie-piece also presents a convenientsupport for a cutting mechanism now to be described. I

Secured to and projectingin a generally upward direction from the tie-piece are two studs 316 which, as best shown in plan in Fig. 3, present guides for a cross-head 318 which carries a knife 320,-best shown in Fig. 7. Preferably, the platen 310 and the supporting tie-piece 312 are slotted as at 322 to present an entrance for the knife, thereby to ensure complete severance of the web when the knife; descends. A- stripper 32% which extends the entire width of the web and is secured to thetie-piece, ensures therelease of the web ofthe paper from the knife when the latter ascends after severingthe web to form the wrapper.

"pair of springs 2326 press the wrapper against the platen and ensure its accurate introduction into place between two convolutions of the'slieets about the tube.

The means for holding the web of paper stationary adjacent the cutting point during the operation of severing the web to form the wrapper, and for holding the latter in fixed position until the proper moment for its introduction between two adjacent convolutions of the waxed paper, will now be described, reference being had to-Fig. 7. The cross-head carries two pairs of i)lungers M8, which are adapted to press the web of paper upon the platen on opposites sides of the slot into which the knife descends, each plunger to this end being resiliently mounted as by the provision of a h'elically coiled spring 35() encircling a shank 352 presented by the plunger, one end of the spring being seated against an abiit-- ment 35 i carried by the plunger, and its other end against a fixed abutment, herein a plug 356, threaded into the upper end of a chamber 358 formed in the cross-head. The descentof the plunger may be hunted by continued descent of the cross-head and while thesprings are being further compressed, thus holding the web with even Ill greater firmness, the-knife descends into and through the paper, tlierebysevering the web.

One pair of plungers (those below the lineof cleavage of the-paper) is utilized to hold the wrapper thus severed until the propermoment; forit to be taken by the package. .By reference to the right-hand.

the wrapper until jnst the proper moment for its release, which. is when the leading ends of the waxed: paper sheets have traveled, ton; point where the-outer surface of the outermost sheet contacts with the upper surfa-ce'of the wrapper.- The cam w-hiclrcontrolsthe reciprocation, ofthe cross-head is so timed as to elevate the plungers, and to release the wrapper: at this particular point inthe operation; Inpractice, it is found that the introduction of about an. inch of the -.wra.pper1 between adjacent convolutions of the waxed paper is suflicient to cause the wrapper: to 1 be grasped with sufficient firmness: to. ensure its being wound about the layers. of waxedqpaper. The length of the wrapper is such asto, encompass the roll of waxed paper, and to, proyide a sufficient overlap, w-hiclrin. practice usually amounts to from two and one-half to two and threequart-ers inches.

To forma secure and dust-proof package, it is desirable toprovide the oyerlapping margin of: the wrapper with ari adhesiye. and; to cause it to. adhere: to the body of the wrapper. This can be accomplished convenientlyby the. use of the adhesive-applying mechanism which will now be described, reference being had at first to Fig. 5. A: fountain Sfikis, suitably disposed with relationto the-web of paper, preferably above the platenandforward, of the knife, considered with reference to the-travel. of: the web. Thisfouutain may be-suitablysupported. upon the frame as by means of a, rod; 366. A- fountain 13011368, submerged in a. bath of suitableadhesive, transfers coatingof the latter to-a distributing roll 370, from which it is taken by a vibrating transfer! roll 3772, w hiolrcontacts alternately with the distributingroll, and with the web of papec onthe platenat. a point just forward .of the knife.

Referr-ing now to Fig. 8, the fountainroll is secured to. a shaft. 374, which extends through the ends. of' the fountain, and is mounted in suitable bearings in the side frames-12. Referringto the'left-hand side of Fig. 3, secured; to the outer end; of the shaft 37 is. a hand-wheel 376, by means of which. the shaft may be turned by hand, preliminarily tOillEStiLl'lllllQ of the machine intooperation. The hub of this hand wheel is proiided with an arm 378, which constitutes a carrier for a pawl 380 adapted for. cooperation with a; ratchet 382, which is loosely mounted on the shaft. Suitably affixed tothe hub ofthis-ratchctis a sprocket heelBS l, which, asbestshown in Fig. 2, is-connectedby a chain 386 with a sprocket wheel 388, the latterbeing affixedto the shaft 34L hereinbefore described in connection with the mechanism for feeding the piles of waxed paper to the point of assembly with the tubes. Also secured to the shaft 34;,is a spur gear 390, which meshes with asecondxspur: gear 39.2, the latter being secured-tea! shaft 3%, which is journaled inisuitable bearings in the side frames 12 ofthe machine To the other end this shaft Fig. l) isseeured a spur gear 396, whiohineslies with and driven by a sp urgear 152. The train of gearing just describedi rotates the fountain roll in the direction of the arrow applied thereto in Eig. 5,

The distributing roll is secured to a shaft 398, which is adjustable toward and. from the'fountain roll, as by being journalcd in eccentric bearings; 4-09, one of which is. wellshown inEig. 1, the same being provided with handles 402-, bymeans of. which the bearings may be rotated to adjust the distributing roll; toward'and from the fountain roll, thereby to obtain the proper pressure of one against the other. Preferably the distributing roll is driven positively (see Fig. 3), as byv gears LO l and; 406, meshing with eachother and secured to the fountain roll and distributor roll shafts, respectively.

Vibrationof the transfer. roll 372 to cause the same to Contact with the distributing roll and the wrapper inalternation may be accomplished by the mechanism, now to be described, reference. being had to Fig. The transfer roll is secured to shaft l-()8, which has its ends journaled in. arms 4-10, the latter beingseeurerhto av rockshaft 412. to. which isalso secured an arniatl t. This arm iscoiz ncctcd; by a, link 41.6 to a lever 4-18, which, asshown at the lower right-hand portion of Fig: 4- ,.is, formed-on a sleeve 120, whiclris loose T mounted on the shaft 110. Thearm 418 carriesa; cam-roll 422, which cooperates with a r-camv 42 i, the latter. being; secured to the shaft 118.. The (2&111-10lllS maintained in C(DlfltEtCb with the cam by a spring 4-26. lVhen, therefore, the cam is rotated, the motion is transmitted to the transfer roll, thereby causing the latter to contact with the distributing roll, and to re ceive a supply ofadhesiye therefrom, and then to contact with the wrapper, and to transfea adhesive thereto. Preferably, the trans er roll is formed of some suitable {adhesive from the distributor roll under the rollers of printing presses.

thcr yielding tor the same purpose may he DI'QVlOlt-Btl in the connections between the transferi'oll and the cam which actuates it,

as torexample by making the arms 410 s ticiently slender and oil'- such material as to be susceptible oli yielding to a sullicicnt e3;- tcnt." i

It is found that best results are to be had liiycausing thetranst'er roll to rotate in a d' "ection opposite to that of the distributing roll when in contact therewith, as the transfer roll removes a greati-n' amount of such circumstances. 'lhc mechanism imrot-ating the transtcr roll will nowbe descfribed, reference being had to the righthand'portion of Fig. To one end of the shaft 408 of the transfer roll. is secured a 'spur gear 428, which meshes with and driven by a sour. gear 430, to which one end of a flciiible' shartt-4i32 secured, the

otherfendof the flexible shaft beingsccured to a spur gear 434, wh'iclnas shown in Fig, 5 meshes with and is driven by a spur gear 436,, the latter being secured to the shaft 398 ol the: distrilniting roll 3T0. follows that the transfer roll is continuously rotated, but in. a direction opposite to that of the distributingrolh 4 hen the. transfer roll is brought into contact with the rear marginal portion of the wrapper adjacent the line along which the'web is severed, a band ofadhesive is applied to the wrapper, thewidth depend ing upon "the length of time the transfer roll remains in. contact with the'wrapper during the forward motion ot the latter. In

practice, it is found that a band, five-eighths of an inchfwide measured, in the direction of the travelrot thewrapper gives excellent results. When, subsequently' during the rotation of the package by the rotating mechanism, the gunnned margin ot the wrapper is brought into contact with the body of the'lattcr, it is caused to adhere thereto by reason of the pressure which is exerted by the segments 90 and 92 (see' Fig. 5). x I,

The next step in the operation ot the machine Is to discharge the package from the rotating mechanism. 'This is accomplished by simply withdrawing the plugs from the ends of the tube, and 'contemporaneously swinging the segment 90 from the position shown in full lines inFig. 5 to the lowermost position shown in dotted lines therein.

ments 438, with appropriate periocs oi t the cam in i 1g.

between the segments 438.

This permits the. package to descend the third raceway 100. lVhile the package might now be considered complete, we prefor to employ a wrapper which is wider than the length of the tube, and to tuck the projecting ends of the wrapper into the ends of the tube, as in this way protection is allordedlor the edges of the waxed paper, whichniight otherwise be soiled. To these ends, the package is now delivered by the raceway 100 into a receptacle presented by a pair of segments 438, which are caused to move toward and from each other, thercby to open and receive the package, and then to close and hold the. latter during the tucle ing of the ends. In the present embodiment, this is conveniently accomplished by mounting'the segments on arms 440, which are caused to move in unison, as by the, pro vision ofintermcshingsegmental gears 4-41.

"Refcrringto Fig. 4, it will be observed that there are two pairs of arms 440, one .pair for eaclr-o'f the segments. As shown in this figure, one pair is secured to a sleeve 44), which is loosely mounted on the shaft 118. The other pair (see- Fig. 5) issccured to a rock shaft 444, which is mounted in bearings in the side frames 12 (see Figs. 1 and 2). j 4

' The to and fro movementoi. the arms 4 h) securedto the sleeve 44.), as best shown in Fig. and carrying a cam-roll 448, which cooperates with acam 450, against which it is held bya spring 452, which is attached at one end to one of the arms 440 and at its other end to the shaft 80. it follows thatrotation of the c in is accom nmiedby opening and closing movements of the indicated by the outline o which shows the p:

the relative positions which. they occupy at the beginning of a period of rest in. the closed position of the segments, which period is followed by their opening movement for the receipt of the package. i

The mechanism for crimping the project ing ends of the wrapper and tucking them into the ends of the tube will now be described, reference being had at first to Fig. 10. This crimping andtuckiug mechanism is induplicate, and a description of one set will sufliee'forboth. 'Attached to the outer face of each of said frames 12- is a bracket 454, which presents a guide 456 fora reciprocable rod 458,- which is axiallyaligncd with the package when the latter is held The inner end of this rod carries a plural i y o1? lingers 460, herein four, each of which is fulcrumed on a pivot 462, and carries at its outer end a cam-roll 464. Each of these rolls c oper: ates with a fixed cam- 466, conveniently formed as an integral part ofthe bracket '95 is accomplished by providing an arm 44h l lil (ill 454:. Oppositely disposed fingers are connected to each other by springs 4-68, which maintain the cam-rolls in contact with their respective cams.

Each of the rods 458 is given an in and out movement by mechanism presently to be described, as a result of which the fingers are caused to travel along the paths indicated by the reverse-curved, broken lines, and the arrows at the left-hand portion of Fig. 10, during" which the fingers close on the projecting end of the wrapper, crimp the same, and finally thrust the wrapper into the end of the tube, the final position being that which is clearly shown in Fig. 6.

The mechanism for recipro'catin; the rods 458 will now be described, referring to Fig. 6. i-kttached to the outer end of each rod is a yoke 470, the ends of which are connected by links 472 with the forked end of a. lever and carries a canrroll L76 cooperating with a barrel cam L'ZS, the latter being secured to the shaft 180. When, therefore, the cam is rotated, the lever is swung to and fro, and the desired reciprocating motion is imparted to the; rods which carry the crimping and tucking fingers. After the ends of the wrapper have been tucked into the ends of the tube. the package is complete, and it is then released by the opening," of the segments 438 (see Fig. 5), and falls onto a chute 480, which may guide the package to the desired point of delivery. Occasionally it has been found thata package tends to adhere to the left-hand segment in Fig. 5. To cause the release of the package from the segment under such circumstances, we have provided a pair of fixed fingers 4:82, suitably formed on or secured to the bracket 96, and have provided corresponding openine's 484: in the adjacent segment 438, whereby when the latter recedes, the package, if it should happen to adhere to the segment, is brought up against the fingers and is thereby detached from the segment.

In the present example, it is found convenient to drive the hopper-agitating mechanismbv a train of gearing, including a sprocket wheel $86 (see Fig". 1) secured to the shaft 48, and connected by a. chain-4S8 to a sprocket 4 90, which is secured to a shaft 492. To the other end of this shaft (see l ig. 2) is secured a sprocket wheel 494, connected by a chain 496 to a sprocket wheel 498 secured to the shaft 180.

The general operation of the machine should be understood from the foregoing description, but. will now be summarized, referring to Fig. 5. The tubes are fed one by one from the hopper to the point of assembly with the waxed paper sheets and the wrapper. The tube is rotated contraclockwise, as viewed in Fig. 5, and a pile of waxed paper-sheets is advanced to apoint which is fulcrumed on the pivot 204,-

where it isseized by the grippers and is clamped onto the tube, which is then rotated to wind the sheets about the tube.

While the rear ends of the waxed paper sheets are still lying on a table, and the forward ends of the sheets are in some such position as that represented in Fig. 7, the web of paper from which the wrapper is to be severed is fed forward to present its free end between the tube and the waxed paper. The knife severs the web, thus fornr iDQ' wrapper, which, however, is prevented from being drawn forward by the frictional engagement with the waxed paper until the winding: of the latter has reached the proper point, whereupon the wrapper is released and is allowed to wind about the sheets, which by this time are completely wound on the tube.

During the first part of the advance of the wrapper, a band of adhesive material is applied to its rear marginal portion, and when the wrapper is finally completely wound about the package, the adhesive adheres to the body of the wrapper. The package is then released, and is allowed to pass on to the crimping and tucking mechanism, which crimps the projecting ends of the wrapper and tucks them into the ends of the tube. The completed package is then released, and allowed to gravitate toward the point of delivery.
