` `Applicatien lfiled January This inventionrelates to labeling machines and particularly pertains to means for automaticallyl applying labels to the side walls of cans and like containers. In my co-pend- 5 ing application entitled Method and apparatus for fastening labels on noncircular cans and containers, filed August 13, 1923,

S. N. 657.057 now Patent No. 1,653,495, De-

cember 20, 1927, means were shown for atl taching labels to the side walls of noncircu lar cans, particularly cans of elliptical and square shapes. v-Inthe present instance it has been theobject of the invention to provide means by which labels may be automatically wrapped around'cans of any shape and size and fastened thereto.

The present invention vcontemplates the provision ofan endless conveyor upon which cans are ordinarily positioned and by which the cans'are advanced through the machine in a vertical position and are manipulated as they advance, said structure also including label holding and releasing means and paste applying lmeans whereby a label will bc r pasted onto the can and will be neatly wrapped therearound as it advances.

The invention is illustrated by way of example in the: accompanying drawings in which- Figure 1 is a view in side elevation showing the can labeling machine with which the present invention is concerned, adapted for use with fiat oval cans.

Referring more particularly to the drawings, 10 and 11 indicate the supporting legs of the labeling machine. These legs are connected by horizontal tie rods 12 near their feet and are suitably connected at their upper ends by a bed plate 13 bolted thereupon and supported thereby. As shown in Fig. 6 of the drawings, the legs 10 and 11 are ofthe A frame type, thus providing suitable support for all the mechanism required. Mounted upon one end of the connecting structure 12 is a driving motor 15 carrying a driving pinion 16. This pinion is in mesh with a reducing gear 17 on a jacket shaft 18. The shaft 18 is carried in suitable bearings 19 fixedto the end frame member 11. A pinion 20 is fixed to the jacket shaft 18 and is in mesh with a gear 21. The gear 21 is fixed to and carried by a shaft 22 mounted in bearings 23 and carried on the frame member 11. This sprocket shaft 22 carries a sprocket wheel 24 around which an endless sprocket chain 25 is passed. This chain also passes around a sprocket 26-disposedi at the opposite end of the machine and carried upon a shaft 27 mounted in bearings 28. The bearings 28 are fastened to the end frame member l0. The.

shafts 22 and 2 7 are therefore supported Iat parallel relation to each other-and in the same vhorizontal plane, while the .sprockets 24 and'26 are carried upon the shafts in the -itl figuration, .for example; in Fig. 2 thechucks are shown as being oval, in Figl` 3 they are shown as being square and in Figs. 13 and 14 they are shown as being circular. The chucks are made of different shape tov accommodate cans of different style "and to insurethat the chuck will fit wit-hin the recessed bottom of the particular' type of can upon whichlabels are being applied, and will conform`l to the contour double seamed periphery. sothatthe cans will be held against movement with relation to the chuck as it advancesthrough the machine, as will be hereinafter. described. ri`he chucks rotate as advanced and-it will be understood that when the chucks arebeing used with non-circular cansl the cans 'will positively rotate with chucks. -In the event, however, that-circular cans are beingzused it is necessary to provide ratchet teeth 30,

as shown in Fi gs. 13 and 14, byfwhi'ch the bottoni o f the can may be engaged and positively driven. In any event, the chucks are mounted upon pins 31, carried upon certain links of the endless conveyorI chain 25,4and at spaced equal intervals throughout the 'lengthof-the. chain. Formed as apart of the chuck Inechanism and carried directly therebeneathf -is a gear 32, which is intended to rollalong a gear rack 33. carried upon the bed frame 13, .as more clearly shown in Fig. 6 of the drawing. It will be seen that the chucks 29comprise a 7top plate 34 adapted to tit-within the can and a downwardly extendingv =hub 35H around" which the gear A32 is mountedand held by screwsa. These screws also secure a'vcircular plate 36 in positionbeneath thegear. This plate is of a diameter substantially the same lis' the outside diameter of the gear 32, or slightly larger, and vbears against a vertical shoulder. 37 of the bed Vplate to :aid in guiding the chucks as they rotate and ad- Vance through the machine.l The pins=31 extend downwardly-through bushings 38.

The lower run of sprocket'chain as indicated in Figs. 1 and 6 passes horizontally'between guide bars 39'and 40. 'These bars are supported upon thecrossframe members .'41 of the end frames 10 and 11.' In Fig. 6 vit will.

be noted that the chuck is for an oval can and thatwin the view'tliere shown the uppermost chuck isdisposed with its major axis parallel to -the plane ofthe view and with its lowermost chuck with its .minor-'axis parafllel to the plane of the'view. Itwill 'alsobe noted that the gear 32 of the lower chuck does not engage anv gear rack as it passes along the guides 39 and 40 and that-inthe event of'noncircular cans the Iguides' 39 and'40 will hold the chucks against rotation and present them to thel can-feedingdevi'ce in proper position. Supporting arms 42 aresecured atinter- V vals throughout the length of the guidev rails 39y and 46. 15VThese arms overhang the lower runt., sprocxet chain 25 vand-'carry spring stabilizinf'r members 43, by which the chain 1s move upwardlylaround the sprocket wheel 26 to the labeling position, they will be between the guide rails and will be held in position thereby.

It will be-uuderstood that cans will be continuously fed into the machine from a run ofcansand it has been found inpractice that cans of-diferent style must be yfed into the machine in a different manner, for example; round and oval cans are fed into the machine on an inclined runway 44 as shown in Fig. 1, while in the case of square cans the runway may behorizontally disposed as shown at 45 in Fig. 4. In the case of oval cans the cans will move down ythe'runway as indicated by dotted lines at 46 in Figav 1, yand will then move into engagement with. separable jaws 4T and 43. These jaws .at their forward end conform substantially to the contour of the ovalcansand are yieldably held in position by springs v49 and 50, so that the jaws will act as an escapement .for the cans, while permittingthe cans to slide downwardly along rails 451 'and 52 as seen in Fig. 8. `l Acentralwsupporting member 53 disposed beneath the cans and in their pathway support them and prevent them from being struck along their rear edges by the upwardlyfswinging chucks, which would result in moving the can into the machine in advance of the chuck and thus jamming thc machine, for it will be understood thatit is intended that the forward edge of the chuck sliallfengagethe forward edge of the lip of the can bottom. Other yieldable ratei-ding means are also shown for the oval cans in 1. Here it will be seen that rollers and are disposed in the pathat the top of the can and beardownwardly and against it to prevent the can from jumping up when it is engaged by the chuck and thus causing the can and chuck to positively meet and engage and then proceedinto the machine `in an interlocked rela-tion'.v Rollers 56 are' indicatedin Figs. 5 and .5, where it will be seen that a spring-pressed Ibrake member 56 engages the roller shafttoretard the can. As the chuck and can carried thereby move onwardly into the machine the top of the can Ais `borne against .by-a lexi'bleresilient rail which extends throughout the length of the upper horizontal run of the chain and is yieldably held 'at intervals by spring 58. In this manner each of the several 'cans passing through the machine at any one time may be continuously, yieldably and separately held upon their individualrchucks without danger of displacementuntil the'cans engage apair of carryb vrails 59 at lthe opposite endet the machine., v

.Intliejforiii of the invention shown in Figs. 3, 4 and?, automatic'cscapement means for cans isfpro'vided. This consists of a spring blade"60'beneath which the cans must pass and with which they will be engaged. rThis spring blade isv pivotally mounted upon a pin 61 carried by a superstructure 62. the blade is pivoted nearI the incoming cans and is free to swing upwardly as the cans pass y. beneath it.` This, however, is limited by a positively operating escapement mechanism which comprises a pair of jaws 63 and 6l dispose-d along opposite sides of the path ot travel of the can. The forward ends oi these jaws areformed with horizontal ledges 65 onto 'which the canmay pass. The forward ends ot' theseledges are formed with additional offset ledges which insure that the Ylorward end ofthe can lwill be held upwardly yand out of premature engagement by the chuck. The end sof the gaws are grooved 1nwardly Kand when the can moves down into a condition to be discharged from between the jaws, the jaws 63 and 64 will swing outwardly against lthe'te'nsion of the spring 50. These jaws are pivotally mounted upon vcrtical shafts 67 disposed upon opposite sides of the 'path of travel of can.

' One 4oli thejaws carries an adjusting screw 68 which bears against bell crank 60 upon a horizontal pivot pin 70, suitably supporte-a by an upright'll. The head of the/adjust-I ing screw 68 bears against the free end o l the vertical arm of the bell crank. The horizontal arm of the bell crank is formed with anA opening'through which a rod 79. passes. Ahelical spring 73 circumscribes the lower end of the rod and rest-s against the upper horizontal face of the bell crank arm. An adjusting nut 7 4 on the rod rests against the upper end of the spring, while a locknut 7 5 is mounted upon the lower end of the rod 72 and beneath thel horizontal arm of the bell crank 69. The rod 72 is pivotally connected by a. pin`7 6 to ahorizontal lever 77 carried on. a pin 78. This lever swings vertically and its outer free end 79 bears against a vertical sliding pin807 carried in an arm 9 0 mountedupon the upright 71. This pm is providedat its upper end with a spring` 91"- beneath which the' horizontal spring blade 60 is positioned. The spring 91 rests upon the arm 90. The lower end of the operating pin' is adapted to not only rest against the free endl: of the vertical swinging escapcment blade 60,'tlius when the two jaws 63 and 64; or 47 and 48 are `swung about one of the iaws will act torelieve the escapement mech.-v anisrm'and will thereby insure that a can will only bc released' in proper timcdrelation to a chuck'whicli has engaged that particular can.

By reference to Fie. 7 it will be seen that arm 64.- is provided with an adjustingy screw 93 by which the inward movement, ofthe arm will be limited 'as 'determined by the par! ticular can with which the machine is used.

It is the theory of the present inventiony that a can upon which a label is to he applied will be continuously advancodwhile vertical.- ly aligned and horizontally moving, andwill rotate through the machine, and during the advance and rotation oi `he can through thev machine it will atsuccessive points in'its rotation receive an application oliy paste to' its' side wall and that thereafter this paste, carried by the sidewall will act to automatically pick label from alabel stack as the can icontinuously moves and will thcreaftercause the label to be wrapped around the can .and pasted thereto during the progressive opera 'tion ol the can. through the machine. ln

order to bring about these results', paste ap,-I

plying stations are provided along one side l" the path of travel of the cans `and a label supplying station is provided along the op` The paste applying mechanism includes thrce'stations represented by rollers 9st, 95 and 06. These rollers as shown in l4`ig.`6 of the drawings are formed with plurality ot spaced circumlierentially extending grooves 97, which makes it possible for the paste to be satisfactorily carried by the rollers from distributing rollers 9S. rlhc paste applying rollers 9i to 96, inclusive are mounted upon vertically disposed shafts 09, each carrying beveled gear pinion upon its upper end. The shafts 00 are carried on horizontal swing* ing radius arms 101 which are mounted upon vertical pivots 102 which permit the paste applying rollers to have a yicldable movement with relation to the surface ot the can wall upon which they are designed to apply paste.

'Disposed in thepath of 4travel of the ad-- vanoing canand at the point Where the label has completely Wrappedaround the can and overlapped, the overlapping portion contacts with a rubber roller 151. This roller is especially made of sponge rubber so that it will yieldingly lwipe and smooth the overlapping vends ofthe label and thus finish the labeling operation. The roller is mounted upon a vertical shaft 152, driven from a horizontal shaft 153 through gears 154 and 155. The gears are in turn driven by a sprocket chain 156 which led l around sprocket on the shaft 106. The rubber roller rotates-'in the same direction as the dir ectionof movement of the surface of the can disposed on the opposite side of the path of travel of the can, and a one half turn in advance in the rotation of the can is avertically disposed brush 157 which 'is mounted upona shaft 158. This finally brushes and wipes ythe overlapping joint at the end of the label. vThe shaft 158 is driven through suit-able gearing connecting it with shaft 159 which carries a sprocket 160 driven by sprocket chain 161 receiving its power from sprocket wheel 162 on shaftlS.

In operation of the labeling machine cans are fed in on a runway`44, 4to the machine. When square cans are being labeled this runway is disposed horizontally and thc cans move in a direct line horizontally, but when round or oval c ans are delivered to the machine it is desirable to .dispose the canehute 44 vat an inclinelto the'hor'izontal, so'thatfthe forward edge of each ofthe cans will project downwardly into the path of travellof the chuck which will tend to pull the 'can with the chuck, so that the can will fit snugly over the chuck as it reaches a horizontal direction of travel.

As indicated in Fig. 1 offthedrawin'gs, oval cans are being fed into the machine.4 In this case thesey cans move beneath rollers and 56. As they enter the machine, the rollers are yieldably held by spring members shown above them in F ig. 1. Rollei' 56 is more clearly shown in Figs. 5 and .5, Where it will be seen that there are two separate roller elements mounted upon a shaft with afriction brake member 56 disposed between them.A This brake member retards rotation of the rollers and their shaft, and engages the can to slightly retard its advance and to insure that the can will snugly fit upon the advancing chuck.

The rollers 55 and 56 are preferably formed of rubber, so that they will yieldably engage the upper edge of the can and firmly hold it during the positioning operation upon the chucks. After the can has become seated on a chuck which is to carry it throughthe machine, it is advanced in the direction of the arrow a, as indicated in Figs. 2 and 1 5. During this advance thegear-SQ, whichis moving with the chuck and is in engagement with therack 33, will advance and cause the ehuck'to rotate.

VIn the installation shown in Fig. 2, the oval can will rotate until its major axiswill be disposed transversely v of the longitudinal Ipath of travel of the can through the ma cln'iie At this time va limited vertical. area on the end of the can will be in contaetwith the paste applying roller 94. This ioller is rotated in the direction of the arrow b, as indicated in Fig. 15 and Vwill apply a sufficient amount of paste" upon the end of the can to thereafter engage and'hold a label. -As the can continues to, advance through the machine in thedirectionlof'the arrow a t-lie can will rotate'until the end ofthe can upon which paste has beenpreviously applied.- the chuck holding the can-will rotate a half revolution and then come inI contact with the foremost, label 146 in the label magazine. At the same timethe :can will engage members 143 and 1,44, andfpress these members inwardly against thetension of spring 145. This willl cause -the knives 142, carried by the members-143 and 144, to'cut through the end edge of the label as indicated at 147 and 148 in Fig. 15.` Asthe cancontinues to rotate the label will be 'pulledoi'er these knives as it adheres to the can aufdwill iiiove therewith. 4At the time the' label is being aflixed to ,the can, thelopp'osite end lofthe can is in contact with apaste applying vroller 95, whereby another patch of paste lis applied to the diametrically-oppositelend oflthe can. As the cancontinues'to rotate the first patch of pastey marked will lmove ,toaposition' in contact with a paste applying'roller 96,'and the second patch of pastel marked y will move 1nto contact withftheflabel at a point intermediate it`s ends. During this rotation the label will befg'i'adua'lly stripped from the stack 'of labels'in' theV inag'aaine, and will be pulled over the pins 138 and 139 and will be drawn taut' arpundthe can.

'I hen the paste'spota and the label :idhernig thereto reaches the paste applying roller 96, paste will'be applied to the adhering end of the label-so thatcs the spot as pursues another half revolution to the end of the label magazine, the free end of the label will be wrapped around and over the paste carrying' end of the label, and the labeling operation 'will thus 'becompleted t this same time, when the overlapping ends ofthe labels are pasted together, the spot i' will come into'engagement with a rubber roller 151, by which the label will be smoothed down onto the paste and as the can continues to rotate it will pass a brush 157, which will brush off any particles of paste that show on the label and smooth the label down onto the can.'v I

t will be understood that in the case of square cansa labeling operation lwill be sub-I stantiallythe saine, with'the exception that the corners of the cans will s trike the rollers, and in that event itis necessary to. adjust the lane between the rollers and the magazine to accommodate the dimensions of the can, and

Al El to lalso adjust the position ot the paste applying rollers with relation to each other, to insure that the corners of the can strike the rollers.

In feeding the oval cans from the can chute 44, it is only necessary to rotate the feeding movement by spring arms 47 and 48 until the forward edge of the can is engaged by the chuck.

In connection with square cans it has been deemed advisable to move the cans vertically and to provide an automatic escapement mechanism as particularly shown in Figs. 3 and 4. Here it will be seen that as the cans pass into a machine they encounter yieldable arms 63 and 64. These arms will remain in position until the chuck strikes the lugs 66 on the arms, at which time they will spread and release the can as the arms swiner outwardly to spread the escapement mecthanisms of F i gs. 3, i and 7 for spreading to relieve pressure upon the overhead spring member G0,

and to permit the can to advance while being positioned upon the chuck.

It will be seen from an examination of Figs. l and 6 that the cans are held to travel beneath a yieldable spring member 57 so that they will not be displaced while in the machine and cause it to It will thus be seen that the device here disclosed will act rapidly and with certainty to automatically apply labels to cans of any configuration.

While I have shown the preferred form of my invention as now known to me, it is to be understood that various changes may be made in its construction without departing from the spirit of the invention as claimed.

Having thus described my invention, what I claim and desire to Secure by Letters Patent is:
