To'all'wkom' it marrone-fn? United States.- of' America, residing hat Springfield, inthe vcounty-of,11ampdenl` and StateI ofA Massachusetts, have invented '.c'ertain new"and useful Improvements `in Trapping-Machines, off whichthe followingr'is -a specification. v

his invention relates tol improvements inl wrapping'machines and, while the invention 1s capable of generalappllcatlon, it nds one advantageous specific use as a means-for automaticallyfpackaging stacks of articles,

such as lozenges'and the like, for example. According-to one feature of the invention,

la `plurality of articles to be wrapped are carried on a turret movable step by step and are automatically transferredto, and -carry therewith suitablel wrapping L material into, another step by step movable turret, wherein the articles are wrapped, and subsequently discharged therefrom.

lAccording to another feature of'the invention, af plurality of pockets are provided in an intermittently'movable turret and are 4each adapted to'receive and hold an article to be wrapped, and each pocketvconsists of relatively movable members which are normally held in coperatiye relation to grip the-articles. and prevent movement thereofin any direction, means being provided to automatically andA successively-fopen the pockets to receive the articles to be wrapped andV wrappers therefor, together with means toE wrap the articles while heldin the pockets and to automatically and vsuccessively open thelatter to release the wrapped articles. y' i According to another feature of the invention,` the articles are entirely wrapped while positioned in 'an intermittentlyv movable turret by improved 'wrapper folding devices carried in-part bythe turret and in part adjacent the path of movement'there-- of, characterized in that folding operations occur during each period of'rest and each step by step movement of the turret from article receiving to package discharging position.

' According to a further feature of the iny "vention, the articles are wrap-pied while icar- I Be itknowinthat we', ELM-AER LSMrrH and ARTI-ron PHI-19N, citizens4 lo -f .the

Fig. 15 is a perspective view of the stacked articles to be wrapped; and

-Figs. 16 to 22 are perspective views illustrating successive steps in the wrapping of the articles.

The machine in general involves two tui step and are arranged with their axes at right angles so' that a face of each is nearly tangential with the periphery of the other. In one turret, the articles are suitably posi- -gtioned for Wrapping and means are provided to automatica ly f transfer the stacks from this turret to the other. )Vrapper feeding mechanism is provided to supplyv wrappers between the turrets and in the transfer Vof articles from the first to the second Wheel the stack is partially Wrapped.' Other means are provided to complete the wrapping of the stacks of articles during'the travel of the second turret and above the latter'is a. discharge apparatus together with means to vremove wrapped articles from the second turret and position them in the apparatus. 'In the latter, the packagesmove slowly step by step to thedesired point of d is` charge and during their travel through the apparatus,`the overlapped gummed edges of the wrappers are held together until the adhesive has firmly' set. ,l

The general frame struct-ure and main driving connect-ions of the machine will now be described. Referring to Figs. 1 and 2; A

represents a bed plate suitably supported.

from the Hoor and mounted below -and adjacent the front wall of the frame is the main drive shaft 25, which is adapted to be driven from a suitable source of power from 'the pulley shown'in Fig. 1.- Arranged at right angles to shaft 25 and driventherefrom by the bevel gears shownA is a shaft 26,

whichA in turn drives by bevelgears a shaft 27 arranged adjacent the rear wall of ythe frame. Upon shafts 25,26, and 27 are mounted the various operating cams to be i later described. Shaft 25 drives by a gear train 28 4a master cam 29 which carries a roll 30 to drive a Geneva cam 31 iixcd on a horizontal shaft 32 arranged above bed A. Shaft 32 may thus b e driven intermittently by cams 29 and' 31 in a now Awell known manner and is arranged to turnninety degrees A' vertlcal on each rotation of shaft 25. shaft 33, mounted substantially centrally on bed A,'is driven bythe bevel gears shown in Figs. 1 and 2 from shaft 32 and, in this in# rets or wheels which are movable step by' stance, at half the speed thereof. Fixed to shaft 33 near the lowerend thereof is a turret 3i which is adapted to carry thearticles to be wrapped by a step by step movement to the wrapping mechanism.

f The turret 3a is movable as shown in Figs.

2 and 4L in a suitable opening formed in bed A. The'shaft 32 has been shown in Fig. 2 as broken oifbut, as indicated in Fig. 1, it extends beyond shaft 33v and, as'shown in Figs. 3 and '8, has fixed thereto a wrapping 'turret 35. Both turrets 3-Lt and 35 are movable step by step by the means described, but the. former, as described, moves only at half the speed of the latter 'and as 'will appear has provision to accommodate twice as many arranged at right angles and the face-of each isl nearly tangential to the peripheryv of the other.

The apparatus'for `delivering wrapped.

articles from turret :35 is carried by av frame B and will be later described in detail. Frame B is supported above turret 35 and extends from the latter in a direction at right angles to ,shaft 32 tov and beyond the rear wall of bed-A. Frame B is supported at one endby 4a bracket (Figs. 3 and 1l) from a frame b secured to bed A- and at the other end from the floor'by means of a suitable standard c(Fig..11). The frame Z) is arranged to support an end of each shaft 32 and 3,3 and other devices to be later described.

The means for feedingthe articles to be.

wrapped to the wrapping turret will next be described. Referring particularly to Figs. 2 and 3, the turret 34 in the illustrated embo'diment Aconsists merely of a plurality (eight in this instance) of radial spokes and slidably mounted on a rod 36 in the outer endof each'is a supporting cradle 36,' which is normally held against the upper face of the spoke as illustrated in Fig. 3 by a spring 3T. The upper surfaceof cradle 36 is concaved to conform to the lower peripheral contour of the articles to be wrapped..

The articles, in this instance, lozenges of elliptical shape, are stacked faceto face as shown in Fig. 15, and the stacks are placed in the cradles, as by an operator, as the cradles successively come to rest in the upper left hand quadrant (Fig. 2). Spring linger" 38 'secured to the spokes of turret 3a extenu upwardly and engage the sides of the stacked articles-in the cradle as best shown in Fig. 3

articles. Theaxes of vturrets 34. and 35 are -and on the ends of the cradles are other springngers 39 which engage the ends of the stack, whereby the latter is held against movement in all directions except upwardly. `rlhe'turret 34 moves step by step in the direction of the arrow (Fig. 2) and each stack of articles successively comes to rest in` under a plate 40 (Fig. 6) which is supported byrods "il slidable .vertically in a bracket is at rest, a -tapper lever 42 pivoted at 43 to frame A andhaving a roll to ridein thev path of a cam 44 is elevated't engage the `secured to frame A.v Plate is spring pressed downwardly and is limited inits downward movement by suitable collars on rods 4l, whereby the plate 4 0 is so supported that the stacked articles d on turret 34 may move freely thereinunder.A While vturret 34 slidable supporting rod of the cradle 38 which is positioned under plate 40. The stack of articles-is thus' carried upwardly and forced against the yieldable plate 40,--

as shown in Figs. 6 and v7, which functions tobring all the articles of a stack into exact alinement before the wrapping operation.- The cradle 36 is subsequently` lowered before' turret 34 is `given its next stepby. step movement. n

After leavingthe'plate 40 the stacked articles are'successively carried to and brought to rest in the'positi0n shown' in Fig. 3, where-y inthe cradle 36 liesvertically below a corresponding-cradle mounted in the wrapping turret 35. The stack of articles is# adapted to be transferred from one cradle to another-while theirrespective turrets are at rest 'by means to .be later'described.

'The means for feeding -thejwrapping material tothe articles willneiitbe described.

The wrapping materialconsists of labels e which are vertically stackedwithin a'ma azine 46 (Figs. 2 and 4)'and asheet f, in t is instance foil or like. material. 'Thefoil in'g" roll form is supported on an arbor 47 and is guided therefrom .by rolls 48 to a'channel 49` in frame A. The strip f extends under-".11l magazine "46 and. beyond the latter, vthe for-4 ward edge of the strip beingdisposed in' the?I vertical plane of actlon.- of a air of shear@ blades 50, pivoted together an to, frame A at 51,-as best shown in Fig. 3. A .pivot'edf bell crank brake lever -52' (Fig. 4) has a part on one arm .to engage the upper face. of stripf in channel 49 andaroll'on the other Iarm to ride in the periphery of a cam 53 fixed on the described'shaft 26.' With the parts positioned, as shown in Fig.. 4, the bra-ke lever acts to hold stripf against movement in. channel 49 and, while the strip 'is thus held,l rolls 48 act to draw` a portion ofthe stripfrom the roll on arbor 47. Rolls 48 are mounted on a bracket 54 (see Fig. 2) rotatably supported intermediate'its ends on-ashaft 55. An arm'56fixed on the latter is'y pivotally connected to an arm 57 which has thereon a roll riding in a path cam 58. 1 The latter is constructed so that shaft 55 is oscillated first in a counterclockwise and then in a clockwise direction, whereby rolls 48 irst draw out a portion of strip f and then recede leaving a slackened portion which is subsequently drawn into the machine by means to be described.

At the forward lower portion of magazinev` 46 is the usual pivoted suction plate 59 (Fig. 4) which is connected by a ii'eXible hose 60 to a suitable pump 61, indicated convention-- ally -in Fig. 2 and actuated by suitable means not shown.' Thel suction plate is refcked downwardly at the propertime by 'levers 62and 62 (Fig. 2) zwhich'are connected together at their ends and pivoted-'to frame-A. The other Lend of lever 62 is pivotally connected'l to the suction plate 59 and the other end 'of leverv 62 vhas'a suitable roll to ride on a cam 63 fixed onthe'described shaft 26. The suction plate functions in the Vusual knownmanner to draw the forward i end of the lower label e in magazine 46 downwardly into the plane of the strip f so that both the strip and label may be gripped by a single means and simultaneously drawn' into themachine. Further description and illustration of the suction plate and' its associated mechanism is unnecessary to an un.

derstanding of this invention -as such construction isnow .well 'known in the fart.,

The strip f and label e are drawn into the machine by reciprocatory nipper mecha- -nism which will'now be describedwith particularfreference to Figs. 4 and 5. A nipper slide A64, havinga fixed jaw .65' thereon, is mounted infram'e A to reciprocate in a' horizontal plane between the described turrets 34 and 35 and .in a vertical plane slightly offset from that passing through the axis of their.\ driving shaft 32 (see Fig. 2). The lower nipper 'j aw 6,6 is pivoted intermediate its ends to slide64 and a coiled spring 67, (Fig. 4) 'the-lattertends to force the rear end of jaw 66 downwardly to close the nippers.` A member 68, substantially of the shape of an inverted lHJ, is pivotedto slide 64 and its lower ends are connected by a cross bar 69, which normally underlies'thefV tothe upper' portion of 'member 68, tends to` move' the cross bar 69 toward thev forward 'rear part ofz-jaw 66and holds it in" the illus-vv i i tfated position in Fig. 4. y A'A spring 70, conj-j nected at oneend toslide 64and at the'other 1 10 end of slide-64. A spring plate 71 secured tol thedes'cribed bracket b as shown in Fig. 4,

has a 'recess therein`, through which the slide 64 and-upper partof member 68 may pass, as best shown in Fig.- 5. .O n the lower -part of plate 71, however, are inwardly -turned Y proj ctions. 72 (Fig. 5) which, when the slide 64 is moved forwardly, engage the forward face of both. legs of the member 68 be- The nipper slide 64 is reciprocated by the following mechanism. A lever 73 fixed on a shaft 'T4 rotatably' supported, as indicated in Figs, 1 and 4, in brackets from frame A, has a forked upper end to receive a. pin projecting from the rear portion of the slide.

Referring to Fig. 1, a lever 7 5 fixed toshaft 74 is connected by a link 76 to one arm of a pivoted bell crank lever 77, and, in the' other end of the latter isa roll which vrides in a path cam .78'xed on the described shaft26. Cam 7 8V is constructed 'to cause slide 64 to advance to strip' and labell gripping position and to then retract to bringthe labele and the strip jI therebelow, over the stack of ar-v ticles (Z in' the mani'ler shown in-`Fig.' 16, while the articles are supportedby turret' 34 .below a cradle in turret.35. As the label e is drawn from thema'gazine, adhesive gis applied to its lower face adJacent one edge thereof in the manner'shown in Figs.Y 16, 17

and18.,

The mechanism forapplying the adhesive will now bev described. An adhesive container 79 is mounted'in vframe A below 4the `path of the -labeliand rotatably supported therein are Wheels 80 and 81, the former being arranged todip into the adhesive and transfer it'to the latter which in turn applies the adhesive tothe label. The wheels 8O and 81 are driven in an'y suitable manner.

F or example, they maybe 'gear connected with a shaftv 82 (Fig. 2), the connections having been omitted in F ig. 2 to avoid con fusion of lines. 'Shaft 82 is driven'intermit'- tently vby theifollo'wing means. A gear 83 (see Fig. 1) loose on shaft 82 isdriven. through a gear train84 from a segmental gear 85 which is fixed to thedescribed bell 'crank lever 77. Gear 83 ,fixed to a` pavvlcarrying 'disk' 86v also .loosely inountedon shaft 82 and adjacent disk 86 is a ratchet 87 i which is ixe'd to shaft 82. It 4will thus be seen that the latter' may be'rQtatedinter-v,l mittently in' one direction; namely, that f shown by the arrovT in Fig. 1,`during theretraction of slide 64. Referring to Fig. 2,

a ratchet 83 is fixed to shaft 82 and a pawl 84 pivoted to frame A is arranged to engage ratchet 83 to hold/shaft 82 from` during the advance movement of the and this extended portion is connected'by a v linkfSS to alever '89 pivoted yat 90 to a bracketon frame A. Thelower blade 50 is also connected byfa link 91 to the lever.89,

the pivotal connection of the latter and the lower blade 50 being disposed to the` left of pivot 51. cam 92, which is indicated onl in Fig.2 and is fixed on-the described g 'gwardlyl from the ends of 4cradle 45.

members 45 97, and 98 constitute what may betermed a `wrapping pocket. Fingers 98 27 is constructed to actuate lever 89 and close the shear blades at the proper time and then to open the blades and hold them open until a succeeding portion of strip f has been `drawn therebetween.

After the foil has been positioned over the `articles and after shears 50 have operated,

the jaw 66 of. the nippers is opened in the following manner. Referring to Fig. 6, a bell .crank lever 93 pivoted at 94 to frameA has a. roll on one arm to ride in a path cam .95 fixed on the described shaft 25. The end of .the other-arm 'underlies the Ipivoted jaw 66, 'as shown inFigs: 4- and 6, andat the` appropriate time 'is moved upwardlyto raise the rear part of jaw 66. As the latter is raised to release the grip on the foil and label, the spring 704moves member 68 so that articles d. Oneach side of cradle '45 are holding blocks 97 and the faces of the latter,

adjacent-to thecradle, are'v recessed to receive" vthe roundedsldes of` the-stack- The two blocks 97 ,coperate'as' shown in Fig. 8 to hold'v the stack ofy articles againsty sidewse f'movement" in cradle45 and endwise movement in the latter i's prevented by spring sngers'98 securedto and extending up- The also have'a wrapping function as will ap.-

'pea-r. -Ea'ch block 97 is fixed on 4the outer ends of a pair of spaced arms 99, and the palrs of arms are pivoted in spaced relation to turret 35 adjacent shaft 32. Intermediate v the block 97 and the pivot of each arm 99 isf a roll 100 and'fxed on each of the described rods96 is a spreader 101, which, when the rods are movedoutwardly by means to be described, .engage rolls 100 and separate the blocks 97 from the cradle 45. The blocks 97 are normally held to the cradle 45 by suitvable .springs which, as shown in Fig. 8 con- .nect Vthe arms99 of one block to the co-rresponding arms of the other block. Pref erably the blocks 97 have a tongue and recess `interlocking engagementv with cradle 45, as best shown in'Figs. 9 andl() to prevent endwiseV movement of the blocks relatively to the cradle.

`Pivoted intermediate its ends at 102 to the .turret 35 and adjacent each cradle 45 is a levep103 on one end of which is a suitable roll and on the other end of which is a folding finger 104. The latter is .curved from pivot 102 asa center and is coextensive in length with the length of cradle 45. The lingers 104 are normally heldin the positions illustrated by springs 105 but are movable to the position, indicated by dotted lines in Fig. 8, when the rolls on levers 103 come in en agement, aswill be later described, with astationary cam plate 106 secured to the described frame b,as shown in Fig. 3.

v`The means for moving'the rods 96 and thusA separating blocks 97 from cradles 45 will next be described. A plate 107 is' loosely mounted on shaft 32 adjacent thev wheel35, as shown in Figs. 1 and 3. Re-

ferring t0 Fig-13, "lXed to plate 107 isha crank .,108 which is'cnnected by a link 109 is-pivoted intermediate its ends 'to frame A and on its lower end bears a roll which rides4 in a path cam 111.l The latteriiS-lconstructed sntbetplateiggygli betumeain the Same Y directioni as ,and at'tle"spee'dwithhturret 35 through an arc of substantially ninety-v yto the upper end of a leve-r 110.-v The latter degrees and then in a reverse direction back into the illustrated position.A A roll 112 isrotatably mounted on one of the rods 96 of each cradle and all the. rolls ride in a cani path formed in plate 107. This path is concentric with shaft 32 except for two subifstantially opposite portions 107 and 1072.

It willbe obvious that, as cam 107 turns in unison with turret' 35 during each step by .step movement, the `relative positions of the rolls 112 with respect to the portions 107'.'

and 1072 do not change. The llow'ermo'st roll 112 will thus move through an arc of' ninety degrees with the cam portion 107 always be'- hind it while another roll 1 12 will move into the lowermost position and above cradle 36.

107 comes to restin the position shown,

lby cradle 36 which moves in unisonv therewith until the blocks 97 have moved back into holding engagement withthe articles and the cradle 96 is fully elevated.

The means'forwrapping the articles will' next be described. Before the articles have been transferred to cradle 96,'the strip of and label 'c are positioned thereabo ve.j jas shown in Fig. 16 .and as already described.

turret 34 to turret 35 will then cause the label e and strip f to'be partially wrapped about the periphery of the stack and the' spring .ngers 98, already described, will ofthe stack, allas shown in Fig.-17, wherein It representsy the end folds fornied by fin-l l gers 98.

Although thelatter will of themselves effect the endfolds h, it is'preferred to first 'crease-the strip f, to facilitate the folding,

and the creasing-means will next be described Vwith reference to Fig-'32.1 Two finers -115 pvoted in spaced relation to frame at 116 and drawn toward one another by suitable springs lf(not' shown) vwhich are wardly to crease lthe paper and start the foldibo" h which'may then be readily completed fingers 98.

As turret 35 comes to rest, cam 107 will be' turned back to its initial position and will engagethe'last-named roll 112 and move it downwardly, wherebythe blocks 97 will be separated, and cradle 96 will be lowered 'toby. the fingers maybe spreadapart in an 110 ivardthe cradle 3,6 on wheel 34. The plateI 107 is so'moved that cam 107 .has a short dwell to hold blocks 97 away from cradle 45 during the transfer ofthe articles thereto.

At this time cradle 36 will be'elevated to transfer ,the stack of articles therein into cradle 96. The means forv accom lishing this result are shown in lFig. 3 an consist of a cam 1.13 (see Fig. 2) on the described shaft 27., whicll'is arranged to actuate a pivoted lever 114. The latter is engageable ,with the lower end of rod 36 and thus liftsV cradle 36 against the tension of spring 3T. The cam 113, which does notshow in Fig. 3

ybut which isindicated in Fig. 2,l is constructed to raise cradle 36 so that the'stack .of articles meets cradle 96 during the relatively short interval in -which cradle 96 is lowered and blocks 97'., separated from the latter.

downward extensions of label Ac and strip are enga ed by a stationary brush 122, of .arcuate form andv concentrically arranged with respect to shaft 32'. Thus, the lastnamed downward extension is laid over the first-named extensionythe finger 104 being" drawn back in timeto Ypermit the gummed edge g to engage the other edge' of label e in overlapping relation. The two overlapped edges. of'the label, now in the tubular form shown in Fig. 19, are brushed into 'intimate engagement during the remainder of the. first step of'movement of wheel 35 and are held together by the brush. during the folding of the tubular end extensions of The end folding operations, "other than the describedV end vfolds h, occur largely while' the articles are at .rest intermediate the upper and lower; extremities of brush' 122. `W'hen the articles are thus positioned finger 104 is completely retracted by spring 105 and folding fingers 123., Apivoted to frame'b at 124, are swung upwardly and force portions i ofthe tubular'end extensions of the'jw'rapper f flat against the ends of the stack, vas shown i'n Fig.,20, the foldsh being'still' held by fingers 98. The 'fingers 123 are connected by a link 125 with a' lever 126, whiclris pivoted intermediate' its ends,.- as shownin Fig. 3, to frame A' and has a roll riding in a path cam 127` securedto the described shaft25. Thefcamf-127 isdirectly in back of another cam to be described and does not, therefore, appear in Fig. 3, but it is clearly indicated in Figs. 1 and 2. Cam 127 is constructed to move fingers 123 upwardly to complete' folds z' and thereafter tracted until a succeeding stack fof. articles is to fbe'operated upon. .l A

Immediately after theA retraction of finvgers 1-14,.foldingffin`gers 128 xed on rods 128 slidably mounted in frame b, are moved radially inward toward wheel 35, and these fingers fold the parts j (see Fig. 21) As shown inFig. 21 the end folds are now completed except for small extensions Ze, and the latter are-received in slots 129 in fingers 128. The rods 128 are connected together and are connected by a link 130 to the upper end of a lever 131 vwhich Yis pivoted intermediate its i ends to frame -A and has a roll on its lower endwhich rides 'lin a path cam 132 fixed to Cam 132 is constructed to movev shaft 25.

` the fingers 123 inwardly to forinthe folds j and then to hold the fingers stationary .un-

til the turret 35 starts its next step by Step movement.- It will thus be seen that the A extensions 7c being positioned in sll'ots 1 29 will be laid downwardly against the` ends of the stack,as shown in Fig. 22. The 4fingers 123 are then retracted and held thus positioned until a succeeding stack of articles is to be operated upon.

The articles, completely wrapped as described, are carried by the next step of move-` ment of turret 35 intothe uppermost position illustrated in Fig.` 3. A plate 114 fixed to brush 122 forms a continuation of the Alatter and cooperates with-the brush to hold the overlapped seams together vuntil the stacks are discharged in a manner. to be described. It will be remembered that, during this step of movement, cam plate`107 moves in unison with wheel whereby l'the rpds 96 are kept stationary, and the wrapped articles are held to cradle 45 by the blocks.

9.7. lImmediately as the wheel 35 comes to rest, however,.cam. plate 107 swings back to the position 'illustra-ted in Fign3 and in its rearward movement cam path 107.2 engages v the uppermost roll 112' and moves its upwardly, raising rods 96 and spreading apart the blocks 97 The wrappedv package is thus released from blocks 97 and as' it is released the rods 96 lift -cradle45.. The4 wrapped package with the overlapped seam in label e uppermost and .in engagement with a spring `plate 133, whichI is fixed to the upper endy of 'brush frame 122 and extends over the AWlieel35 is thus movedto liftthe plate 133. The 'gummed'seam of- Wrapper f is thus 'pressed 'together b'etweenplatev 1 33 and the 'stackpf articles, and the latter is lifted. i

until it alines axially with the rounded ends of two levers l134. The latter are part of the means for transferring the wrapped packshown in Figs.- 11 to 14, inclusive.

The discharge apparatus will next be described. Referring to Figs. 11. 12, and 13,l

upper and lowerbrushes 135 are horizontally arrangedV and, supported from the described frame B, as best shown in. Figs; 11-and 12.

The adjacent ends of brushes 135 are spaced apartA a distance-less than the thickness of the lwrapped package. The wrapped packages are adapted to be moved. intermittently bet-Ween thebrushes bya conveyer and 'are transferred to the conveyer by the described levers 134. The vconveye'r involves two spaced sprocket chains 136 which support between thema plurality of spaced lugs 137.

Referring'toFigs. 12 and 13, chains 13G have rolls 136 thereon which, during the lower tra-vel of the. chains,l ride in.A tracks 137 fixed age from wheel 35 to the discharge apparatus on' frame B, and thev lugs 13 7 are thereby held so that their package engaging portions liev between brushes .135.. The vconvej-'er Achainsl are`mounted on. pairs of. sproekc 138`and 189,'the former being idlers, wh"

the latter are driven by gears 140 from a shaft 141. 142 and loosely mounted intermediate f its.

. ends on shaft 141 is a lever-143 which carries.

at one end a pawl 144 to engage ratchet 142 and at the other end is connected by .a link 145 to a lever 146. The' latter is broken off in F ig.l 11 on account of space limitations but is completely shown in Figs, 2 and'3,fromv which figures it will be seen that the lever is lixed on the rod 121, already described.'

Also fixed on rod 121 is a lever 147 (see Fig. 2) which has -a roll riding in a path cam14 8 fixed to the described shaft 27. Cam 148 is so constructed that lever 146 is rocked to the move in the other' direction due tothe pawl and ratchet driving connection described.

pa ages from'wheel 35to the brushes 135 into such a position that they may subsequently be moved .step by step by the conveyer will nextbe described. Each of the on the' lower ends of arms 157 'which are pivoted at their other ends to frame B, as

levers 134 described is fixed toa vertical rod 149 `which -is mounted near one end of a rod 150. The two rods 150 are slidably supported in frame Bfandare connected together by a bracket 151 (Figs. 11 and 12). The latter is connected by a 4link 152 to the upper end of the described lever 146. Thus,

the levers 134 may be shifted from the position shown in Figs. 3 and 11, wherein their ends are axially valined with the ends of the wrapped package, to the left end of the brushes-135.1, The levers 134 are connected together by arms 153 (see Fig. 14) so that a Tmovement of one will cause a like movement of the other, .and they are normally drawn toward one another vby a spring 154. On

Athe lower end of'one pin 149. a lever 155 is ixed andon the free end of this lever is a roll, which is forced by spring 154 toward a cam plate 156. The lat-ter is supported shown'in Fig. 11. One arm 157 is connected by a link 158VA (Figs. 11 and 14) to the upper end of a lever 159. The latter is not completely shown in Fig. 11 but from Fig. 2

it will be seen that it"i'spivoted at 160 to a .bracket on frame A. The lever 159 extends below pivot ,160 andhas a roll. which rides in the grooved cam- 161 (F ig.`2.). Cam 161 .is constructed to' hold :plate -156'in such a ytill `position that the.ends f levers134 will be held aparta distance greatertha'n the length of the package until the sa'id ends are alined with the ends of the package in. turret 35.

The-cam then causes the plate to move tothe position shown in Fig. 14, so as to 'permit spring 154 to draw the ends of levers 134 to- Fixed vto the latter is a ratchetl tratedposition- During the return stroke of ,levers 134,'the' ward ''ne another to grip the package therel betweenf'l The plate 156 then remains sta-, 'j' tiona'ry while thepacka-ge gripped at its ends by levers 134 is carried by the latter to .tweenbrushes 135, the cam 161-moves the plate 156 so that Ithe levers 1 34nare spread apart-and then remains stationary during the 'return strokeof levers 134.into the illusf chains 136 areoperatedbyjthe means described and `a lug 13.7'will engager the pack-` i age previouslyv inserted between the brushes, as already described, 4and move'it one step. The packages are thereafter carried step by' step between the brushes, the upper of which Tie means 'for transferring the' wrapped C functions to hold the gummed seam of label e, until the adhesive is thoroughly set. It is particularly to be noted Vthat the wrapped articles, being of substantially cylindrical form, would, when propelled4 by lugs 137,

tend t0 roll, due to the frictional engagement of the upper brush 135 therewith. For'ex- W ample, considering Fig.. 1 1, the articles would 4tend to roll in; a counterclockwise g direction when movedto the right and engaged by the upper brush 135. To prevent such rolling and the Aconsequent disengagement of the upper brush 135 with vthe overlapped seam, the lower-brush 135 is pr'ovided, which exerts a like degree ofv fric- 1tional resistance vto movement'ofthe articles.

The articles, when moved 'tofthe right and i engaged by the lower brush,4 tend ,to roll a clockwise direction, and thus the. functin ofthe lower brush is toneutraliz'e ,theunf-:j

The packages may be delivered' by the con'veyer 1 63` to a table 164,01'- any other suitable means, .as-desired. .The operation will now. be briefly 'suinmariz'ed. The articles, such as the 'stacks of l elliptical lozenges illustrated or other gen.- erally'cylindrical articles, aremanually fedto theturret 34 and'successively carried step by` step to l`a 'position adjacent turretv In the event .that 'stacks of articlesftobe wrapped are out of alinement -the stacksvare Vstance ,foilY and labels, to the latter o which 4adhesive is 'appliedr are fedfabove the turret 35.

shortly after they come to rest in under the Each stack of articles is raised from turret 34 and, as it rises, a cradle 445 descends toward the stack. The articles are thereby gripped between the cradles 36 and 45, and the latter move together until' the are first creased by the fingers 115 during the transfer of the articles to facilitate the articles or substantially cylindrical stacks of overlapping relation fiat against the ends of formation of the fold 71,k by the ingers 98 when the articles andwrappers are forced. therebetween and against cradle 45. The insertion of the articles -in the latter causes the stack to be partially wrapped circumferentially and immediately on movement of the turret fingerV 104 moves to lay the ungummed part ofthe label, and the foil thereinunder, against the stack. The finger 104 holds the wrappers in the position shown in Fig. 18` until the turret on further. movement brings the gummed edge' of label c into engagement with the brush 122, whereby the gummed edge/is 'laid down into overlapping engagement with the un-j gummed portion. TheY turret thencomesto rest and While at rest fingers 123 and 128 successively fold portions and j of the tubular end extensions of wrapper f into the stack. The folding of parts j results in the remaining end extension la being lodged in slots 129 and, as the turret moves, these portions are laid flat against the ends of the. stack' and in overlapping'relation with the folds t and j. The'particular. manner of forming the end folds of the package is considered important and advantageous inv the wrapping of substantially rcylindrical articles, for the tubular extensions are sub-' divided into a plurality of sectionswhich are successively foldedin overlapping rela-v tion to form an e'ctive end s eal for the package.

The articles completely wrapped are raised, as the turret again comes to rest, into engagement with the yieldab'le plate 133 and the overlapped gummedI seam of the labelis thereby firmly forced together.v AThe gripi' per levers 134 seize upon the ends of the Wrapped package as the cradle 45 recedes therefrom, and thereafter the levers'pare shifted to carry the package into and between the brushes 135. The gripper leversI have another important function which is to compress .the end folds against the ends of the wrapped stack of articles. Duringv theI transition from the turret 35 to the brushes 135, the seam .ofrlabel c is drawn/ along plate133 and is thoroughly ironedg'tc" `the articles are free the label from wrinkles. The plate furthermore functions to prevent vthe gummed edges from opening.v The lugs 137 move into'engagement with the packages deposited between 'brushes 135 and carry them slowly therebetween by a step stepmotion to the delivery conveyer 163.l The packages are confined between the brushes for a period sufficient to allow the adhesive to firmly set.' A feature of importance in lthe operations described is that the gummed voverlapped edges of the label are held con-A tinuously from the time'when they are overlapped 'until the adhesive has set, lfirst by the.

brush'122 during the movement of the tur- 'ret,' thenv by plate 114', then by plate 133. 'duringthe transfer to brushes 135, and lastly by the'latter.l l
