BOX-LABELING MACHINE.

Specification of Letters Patent.

Patented Dec. 19. I91 1.

Application filed March 8. 1910. Serial No. 548,031.

To all whom it may concern:

lie it known that l. FRRDICRH'K (HYPE-S. a citizen of the Fultcd States of America. and resident of Springfield. in the county of llampden and State of Massachusetts, have invented certain new and useful Improvements in lioxlraheling Machines. of which the following is a full. clear. and exact description.

This invention relates to box labeling machines. and more especially to that class thereof in which the labels are applied to the boxes so as to partially or fully surround the same. while at the same time such labels are gummcd so that they may adhere to the boxes.

More particularly the present machine is intended to apply narrow labels or hands to cigarette boxes and similar devices which are gummed onto the box itself at one point thereof and which must be broken before the box itself can be opened.

The present machine may be considered to be an improvement on the one described and claimed in a patent issued to me numbered 940.674 and dated November 23, 1909, and to which reference may be had.

\Vhile the machine disclosed by the patent just mentioned comprises a pile of labels disposed at one end of the machine, which labels are pulled one by one into position to be gummed onto the box ready to receive it, the present machine comprises two of such piles disposed at opposite sides of a chute through which the boxes are fed one by one. and also a mechanism which is so arranged that first a blank will be taken from one pile and pulled across the path of the box. and subsequently a blank will be taken from the other pile and pulled across the path of the next succeeding box. It will thus be seen that the capacity of the machine is materially increased over that of the former.

Briefly stated. the present machine compriscs what may be termed a hopper into which the boxes to be labeled are stacked and from which the lowermost box is pushed outward into engagement with a plunger whereby each box will be frictionally held or supported while a label band will be pulled into position beneath the box. In the preferred form each label is gummed substantially at both ends thereof, and as the plunger with the box descends into a trough,

the underside of the box will first come in contact with the upper surface of the label and during the continuation of the downward movement of the box. the band will be pulled with its ends around the side edges of the box. whereupon mechanism comes into operation whereby iirst one of the free and gumn'ied ends of the hand will be brought and smoothed over the top surface of the box. so that the band will adhere thereto. it being understood that the plunger which had carried the box downward. has again returned to its upper position so as to leave the path clear for the bandapplying mechanism to operate. After one end of the hand or label has thus been stuck onto the box. a similar mechanism operates on the other free end of the label and brings the same into contact with the top surface of the box. and in the present instance the labels are of such length that the second or last named end will overlap the end already stuck on the box. The several boxes after being branded in the manner above described are forced downward one on top of the other into a retainer which is adapted to retain a number of the boxes frictionally and in such a manner that each additional box pushed into the top of said retainer will move all the preceding boxes downward. so that it will be seen that each box will serve as a means for pressing the label of the preceding box firmly in place and will hold it there for a certain length of time which is generally sufiicient to set the gum, so that when the lowermost box finally drops out of the retainer. the label band is practically permanently attached thereto.

The invention accordingly consists in the features of construction. combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter setforth. and the scope of the application of which will be indicated in the following claims.

The invention has been clearly illustrated in the accompanying drawings in which similar characters denote similar parts, and in which Figure 1 is a plan view of a box-banding machine embodying my invention. Fig. 2 is a front view thereof. Figs. 3 and 4 illustrate in diiferent positions the operation of the label gripping mechanism to be hereinafter referred to. Fig. 5 is a longitudinal .msii

10, 10 of Fig. 1 on an enlarged scale, and 1 illustrates the band-picker. Fig. 11 is a. vertical longitudinal section of the box-receiver and retainer, together with the mechanism for applying the free ends of the label thereto, taken on line 11, 11 of Fig. 1. Fig. 12 shows in perspective view the manner in which the label or band is applied to the box. Fig. 13 is a top view of the compound label gripper whereby labels are taken from opposite ends of the machine, and Fig. 14 is a. section of the nippers taken on line 14, 14 of Fig. 13.

In the drawings, the numeral 20 denotes the bed-plate or base of the machine on which all of the coacting parts for the various operations of gumming and moving the supplied labels, the conveyance of the boxes, and the wrapping of the labels thereon, are mounted, and this bed-plate may be supported by suitable legs as preferred. J ournaled in a. bearing 21 near the right hand end of the machine is the main driving shaft 22 carrying a pulley 23 to which power may be imparted from any convenient source. Splined to the shaft 22, is a clutch-member 24 which may be shifted longitudinally by a hand-lever 25 fulcrumed at 26 on the bedlate, and said clutch-member is adapted to e thrown into engagement with the clutch hub 27, of a pinion 28 loosely mounted upon the shaft 22 and in engagement with a gear secured upon the main operating shaft 30 of the machine. The shaft 30 is journaled in bearings 31, 32 (see Fig. 7) secured upon the bed-plate of the machine, and it carries at its forward end a device for operating the lunger of the machine whereby successive oxes are forced downward to stretch labels around them, respectively, as will hereinafter he described.

Referring first to the box supply mechanism it will be seen by referring to Figs. 2 and 5 that a hopper H is provided for receiving a number of boxes, this hopper consisting preferably of vertical corner-guides between which said boxes may be held in stack and into which loaded boxes may be fed by hand or carried by suitable mecha nism not shown.

The right and left hand sides of the corner guides 33 are cut away in the manner shown in Fig. 5, and the hopper in its entirety is closed at its bottom by a shelf 34 toward which the boxes I) gravitate, and a pusher 35 is provided for pushing the lowermost box in the hopper out. from under the remaining boxes therein and into the plunger previously referred to. This plunger is placed at the side of the hopper ll and consists in its preferred form (see Fig. T) of a rcceiving-membcr flt' having a rear downwardly extending flange against which each incoming box can rest and. which in conjunction with a spring actuated clapper or plate 38 serves as a means for frictionally retaining each incoming box. The clapper 38 is pivoted on a stud 39 in a bracket 40 and has an arm 11 which may be normally actuated by a spring 4-2 to close the clapper and move the same toward the flange 37. above described. The receiving member 36 is secured to the lower end of a yoke 43 which has a stud H for pivotally supporting a roller 45 which latter is adapted to be operated by a cam 46 secured upon the inner end of the driving shaft 30 above mentioned, and said yoke is guided for vertical movement by a pair of guide-rods 47 which are rigidly secured to said yoke and which are adapted to slide through lugs 48 preferably forming a part of the bearing above mentioned, and also through bearings 49 provided on a bracket 50 which may be secured to the underside of the bed-plate 20.

The cam 46 is so formed that during each rotation of the shaft. 30, the plunger, or more particularly speaking, the yoke 43 will be vertically moved twice, so that, in other words, two boxes will be operated upon by the plunger for each rotation of the shaft 30, the operation of the yoke 43 being normally gravitative. while the cam 46 serves for the purpose of positively rais ing the same to its proper position ready to receive a box from the feeding-in mechanism of which the pusher 35. above described, forms a part. The pusher 35 consists substantially of a comparatively thin plate having its forward end bent, as shown in Fig. 5, while its rear end is attached to a block 51 which in turn is secured to a feedslide 52 mounted for sliding movement in a bearing 53 secured to the bed 20 in any convenient manner.

Reciprocatory movement is imparted to the slide 52 by the same mechanism whereby the label transfer is accomplished, the feed-slide 52 being connected by means of a link 54 with the free end of a crank se cured. upon an oscillatory shaft .36 which is journaled in bearings 57 (see Fig. 8) secured to, or forming a part of, a bracket 58 secured to the bed 20. The shaft 56 also carries a pinion 59 the teeth of which are in engagement with a rack 60. which is attached to a. slide 61 mounted for movement in wave provided therefor in the bracket 58. The slide 61 constitutes the principal acting element of the label transfer mechanism, and it is actuated by a. crank 62 secured upon the front end of the shaft 30. I transfer the movement of the crank (32, by a connecting-rod (33. to a stud 6+ which is held in the slide (31. and upon which. is journaled a pinion ($3 one side of which engages and travels along a stationary rack so. while itsdiametrically opposite teeth engage with a rack 6T which is attached to the picker-bar US which carries suitable devices for picking labels from opposite sides of the table. or bed. successively, and bringing the same into proper position beneath the plunger above described.

From the foregoing it will be seen that while the slide ()1 is moved bodily by the crank pin (32 for an amount exactly equal to the throw of said crank-pin ('12. yet the picker-slide GS will, by virtue of the pinion (15 be moved double the distance of the crank throw or of the movement of the slide (31, a feature which in the present instance is provided for the reason that the label-pickers have to travel between the piles of labels a distance which would otherwise require an abnormal length of crank to accomplish the desired result, and it should be noted that by means of compound gearing instead of the single pinion 65, above referred to, I. am enabled to vary the amount of movement of the picker-slide relatively to that of the main slide (31 as circumstances may require. Furthermore, it should be noted that during the movement of the main slide 61. in one direction as caused by the travel of the crank (32 for a distance of 180. the crank whereby the pusher is actuated will make one complete revolution thus causing the pusher 35 to make a complete reciprocation which latter results in first pushing the lowermost box in the hopper H into contact with the plunger and then returning to its retracted position. shown in Fig.

It may be stated at this time that in Fig. 2 the plunger is shown in its uppermost position and also the pusher-crank 55 is illustrated as having arrived nearly at its right hand movement. or in other words, that it has nearly completed its operation of pushing a box beneath the plunger; while in Figs. 5 and (i the pusher is in position to permit a new box to drop in front thereof. while the plunger is in its lowermost position as controlled by the cam 46.

Referring again to Fig. 7. means are provided whereby the clapper 38 will be. opened as soon as the plunger has descended far enough to bring the box contained therein into contact with the label previously pulled under the same. these means consisting of an abutment shown herein as a rod 69 which may be suitably held on the base-plate 20 and the upper end of which is adapted to be en aged by the end of the arm 41 descenduig with the plunger. so that consequently the box contained in the plunger will be released from the plunger and will remain in the position shown in Fig. 5 in which it will be noted that the box with the main body of the label beneath it has been pushed into a retainer chute designated herein by R. This chute consists substantially of a pair of brackets T0. T1 (see Figs. H and 12) forming a passage which is pretably open at the trout and rear so that the progress of the successively descending boxes may be readily seen by the operator.

In order to prevent the boxes from dropping through. and also in order to retain a number oi boxes therein. the bed 2t] is provided with an aperture through which the ledge T0 of bracket T0 projects downwardly and within which is also disposed a plate 73 which cooperates with the ledge TO to clamp boxes between them and which is. furthermore. held in conjunction with the b 'acket 71 by studs T-l, while springs T5 may serve for pushing the plate T3 toward the bracket so as to obtain the required t'rictional contact against the sides of the boxes in the chute, this friction being sutlicient to hold the boxes within the chute. and also so as to require considerable downward push co the part of the phmger. so that hence the labels previously banded around the boxes will be brought into firm contact therewith, and a perfect union will result. From the foregoing. it will be understood that the boxes to be banded are first gravitating iu the hopper. they are then pushed one by one under the plunger sidewise. and are then carried downward and into the chute by the down 'ard movement of the pl 11 nger.

As above stated. the present machine comprises two supplies or p les of labels disposed at opposite sides of the plunger chute. repectively. mechanism being provided cooperative with both piles of labels so as to first take a label from one pile. and subsequently take a label from the other p le. the labels being withdrawn from these piles alternately. Now in order to permit the gripping mechanism to pull labels from thc.-e respective piles. means are provided whereby the top label of each pile is slightly a sed from the pile so as to enable the nippers to catch hold of the end of each label preparatory to its travel beneath the plunger, and in the present instance I take advantage for this purpose of the mechanism whereby the ends of the label are gununed. this gumming mechanism being clearly illustrated in Figs. 1 and 8 of the drawings, Fig. 8 showing a. cross section of the same on line 8, 8 of Fig. 1, but it should be understood that the construction and organization of both gumming devices disposed at the opposite ends of the machine are substantially the same, although the means whereby these gumming mechanisms, respectively, are actuated are slightly different as shown in Fig. 1.

Supported by a bracket 76 attached to the front of the base plate .20, is a gum-box 77 in the walls of which is journaled a shaft 78 extending from end to end of the machine and carrying rollers 79 partially immersed in the gum in the boxes 77. At its right hand end the shaft 78 has a grooved-pulley 80 which is driven by a band 81 passing over lllttl'lllQdlfltCS 82 and actuated by a groovertpulley 88 secured to the main pulley-shaft 22 above mentioned, so that in this manner the shaft 78 with the gum rollers 79 is continuously driven.

The two piles of labels are herein indicated by B and B and are contained in troughs consisting of side walls 8 1, 85, while end gages 86, 87 may be employed to position the blanks longitudinally. These troughs 84, 85 are supported on base-plates 88 (see Fig. 5) which are provided with substantially central hubs for the purpose of securing the same to vertical rods 89 which are guided in brackets 90 secured to the base-plate 20 of the machine and are mounted for vertical movement therein, the organization being such that resilient means such as springs 91 are employed for the purpose of normally raising the plates 88, while, on the other hand, positive means are employed for throwing the plates 88, together with the piles of blanks contained thereon, slightly downward so as to leave the uppermost blank suspended on the lower gummed surfaces of the gummers such as are indicated for instance in Fig. 8 and which comprise gum-pads 92 carried on the end of a reciprocatory frame 93 movable laterally of the machine and in ways 94 so as to bring their lower surfaces into contact with the gumming rollers 79, above men tioned. It should be understood that the frame 93 is movable horizontally only as controlled by a certain mechanism to be hereinafter described, so that after the lower faces of the pads have been supplied with gum by the roller 79, the frame 93 will be moved forward directly over the blank-pile whereupon said blank-pile is permitted to rise to bring the uppermost blank into contact with the gumming pads, after which the blank-pile is again depressed thus leaving the label suspended on the pads and in position to be engaged by the nippers which will then pull the label into position beneath the plunger and the box contained therein.

Means are provided on each of the label holding plates 88, or more particularly speaking, on the rods 89 connected therewith for the purpose of retaining said plates in their depressed condition for the purpose of loading the same with fresh piles of blanks when required, these means consisting substantially of collars 95 having slots 96 within which are disposed pins 97 securely held in the rods 89, these slots permitting the collars 95 to assume positions as indicated in Fig. 5, which position will enable the springs 91 to raise the plates 88 until the lower face of the collar 95 abuts against the underside of the brackets 90. If it is now desired to maintain either one of the plates 88 in its depressed condition, the collar 95 may be raised until the slot 96 is clear of the pin 97, and a slight turning movement of said collar will then keep the same in position above the pin 97 and substantially with its upper face in engagement with the underside of the bracket 90, so that consequently, the plate 88 cannot rise as will be readily understood.

Referring to Fig. 1, it will be seen that the mechanisms for operating the gumming slides 93 are different in their nature, the right hand slide being operated by a cam 98 secured on the shaft 30 and in engagement with a roller 99 journaled on a stud 100' which is fixed in a lever 101. This lever is pivoted at 102 to the base-plate of the machine and its free end is connected by means of a link 108 with the slide 93 disposed at the right hand side of the machine, so that. the rotation of the shaft 30 will by virtue of the shape of the cam 98 impart a rapid reciproeatory movement to the slide which has its greatest dwell in its inward position. \Vhile the cam 98 serves to push the slide 93 outward in a positive manner, a spring 104 attached to the lever 1.08 as at 105 serves to pull the slide 93 inward and into position above the pile of blanks.

The gumming-slide 93 disposed at the left hand end of the machine is preferably actuated by the movement of the picker-bar 68 and in a manner substantially as shown in Figs. 1, 3, 5 and 6, the slide 93 being connected by a link 106 to a lever 107 which is pivoted at 108 on a bracket 109 secured to the base-plate .20, or more particularly speaking, to the ways 94 above mentioned. The pivot spindle 108 is journaled in the bracket 109 and carries at its lower end an arm 110 having at its rearward free end a by-pass dog 111 which is pivoted at 112 on the lever 110 and comes normally to a position shown in Fig. 1 by engaging an abutment pin 113 on the lever as caused by a spring 114. The end of the dog 111 projects into the path of a finger 115 attached to the picker-bar 08, so that when said picker-bar moves toward the lever as seen in Fig. 1, the by-pass 111 will permit said finger 115 to slide by without disturbing the lever 110 and the gummin slide 93 connected therewith. On the ot er hand, when the finger 115 is actuated by the movement of the picker-bar toward the right as seen in Fig. 1, said finger 115 will actuate the by-pass 111 and move the lever 110 so as to positively move the left end gumming slide 93 outward and against the action of a spring 116 which latter becomes effective in quickly returning the slide 93 toward its inward position shown as soon as the finger 115 has passed beyond the engagement with the bypass 111.

As above stated each of the label-carrying plates 88 is positively depressed for a small amount so as to leave the uppermost label suspended from the gummed pads, and this depressing mechanism is substantially alike in both instances, and consists substantially of a lever 117 bifurcated at its free end to straddle a rod 89 and to contact with a pin 118, said lever 117 being secured to a shaft 119 which is journaled in a bracket 120 secured to the base-plate 20 of the machine (see also Fig. 12). At its rear end, the shaft 119 carries an arm 121 rigidly secured thereto and having at its free end a roller 122 which is adapted to be engaged at its upper surface by an inclined cam face such as is shown at 123 on a bar 124 constituting a part of the main slide 61, it being understood that two of such cam-faces 123 are provided to act upon the cam-rollers 122 of both table depressing mechanisms, respectively, Fig. 5 illustrating the left roller 122 depressed and riding alon the level lower surface of the cam 123, while the cam-roller 122 at the right hand end of the machine is free from contact with the cam-face, and the table 88 is consequently in its high position.

It will be noticed by referring to Fig. 5 that the uppermost label is suspended on the pads 92 and that there is a slight space between this label and the rest of the pile on the table 88, so that when this condition exists, the nippers whereby the label is pulled from the pads and across the underside of a box contained in the plunger, may freely engage the very end of the label somewhat in the manner shown in Fig. 5, the particular construction of the nipper mechanism being clearly shown in Figs. 12 to 14 inclusive.

As before stated, the nipper mechanism comprises the bar 68 which is reciprocated by the pinion 65 above mentioned. Rigidly connected to said bar 68, is a stud 125 on which is mounted a sleeve 126 which at its front end carries a sleeve-jaw 127 rigidly connected thereto and cotiperative with a stationary-jaw 128 secured to or forming a part of the bolt or stud 125. While a spring 129 may serve for the purpose of bringin the jaws 127 and 128 together, the jaw 127 is positively opened by a cam-arm 130 attached to or forming a part of the sleeve 126 at the rear end thereof. During the movement of the bar 68 toward the right, the cam-arm 130 will finally come into engagement with a by-pass cam 131 (see Fig. 9) which latter is pivoted at 132 on a bracket 133 secured to the frame of the machine and held in its normal position shown in Fig. 9, and in engagement with a stop-pin 134 by means of a spring 135. This organization will result in swinging the cam-arm 130 as it travels upward upon the cam-face 131, to open the jaw 127 into position shown in dotted lines in Fig. 14 until the drop-off notch in the cam-lever 130 has reached a position, so that the cam-lever can drop over the edge of the cam 131 and the jaws 127, 128 will then be closed by the spring 129. When the bar 68 now returns to the other side of the machine, the by-pass abutment 131 will be simply swung out of the way without in any way interfering with the gripping action existing between the jaws, the position of the several elements being substantially shown in Fig. 6 in which the picker-bar is illustrated as not having as yet fully arrived in its right hand position and the cam-arm 130 is almost ready to drop. From the foregoing, it should be understood that the nippers just described pertain to and act only upon the labels which are supplied at the right hand end of the machine. Similar nippers are arranged to act and feed labels from the left hand end of the machine, these nippers consisting of a stationary jaw 136 attached to or forming a part of the stud 125 above mentioned and cooperative with a movable jaw 137 which is mounted upon a sleeve 138 which may be opened to the position shown in dotted lines in Fig. 14 and against the action of the spring 139 whereby such aws are normally closed. The sleeve 138 is provided with a cam-arm 140 (see also Fig. 2) adapted to engage a by-pass abutment 141 which is similar in construction and operation to the by-pass 131 previously described, and as clearly shown in Figs. 3 and 4 in which the cam-arm 140 is shown in its different positions corresponding to the open and closed position of the nippers, respectively.

Each label is drawn across the top opening of the retainer R while a new box to be labeled is inserted into and held in suspension within the plunger, the label consisting simply of a strip of fiat paper or material stretched out for its full length and resting with its ends in troughs preferably formed in the devices whereby the ends of said labels are ultimatel turned over the edges of the box, respectively, and whereby also the gum-portions of the labels will be pressed so as to envelop the box in a tight manner. These ironing devices serve also for the purpose of stretching the band or label around the box substantially in the manner shown in Fig. 12, in which the construction and manner of operation is clearly illustrated. Loosely journaled on the shaft 119 (at each side of the machine) are a pair of arms 142, 143 which are connected by a tie 144 so as to constitute a rigid structure or yoke which may be rocked in its entirety on said shaft 119. At its free end the yoke Y carries a spindle 145 which at its outer end has a lever 146 attached to one end of a spring 147 whereby said spindle is rotated to bring the ironing device or presser P into forcible contact with the label, while the yoke Y in its entirety may be swung around the axis of the shaft 119 in a. manner to be hereinafter described.

Referring to Fig. 12 it will be noted that the yoke Y is in its normal or retracted position, while the yoke Y has turned the label around the edge of the box and is just on the point of bringing the guminod face of the label into contact with the box itself. the presser P comprising an arm 148 which is trough-shaped to receive the label in its flat condition and which at its free end carries a roller 149 loosely journaled on a spindle 150. Likewise, the yoke Y has a trough-shaped arm 148' with a roller 149 journaled on a spindle 150. In Fig. 12 a pair of boxes are shown held within the retainer, the uppermost box having just been pushed downward by the plunger which action will bend the middle portion of the label around the rollers 149, 14$), so that its ends are still lying within the troughs 148, 148', respectively. The plunger having then again risen, the yoke Y has been rocked to bring the arm 148 with the roller 149 toward the center of the box thus swinging the right hand end of the label around the edge and into contact with the bottom of the uppermost box, while at the same time the yoke Y has remained in its original position but is now ready to perform its function in swinging the left hand end of the label around the left edge of the box and bringing the gummed end-portion thereof into position to overlap the end already gummed on the box and subsequently pressing the same into cohesive contact. Of course, it follows that each label has to be treated in exactly the same manner, and irrespective of the fact whether such label comes from the pile disposed at the right hand end of the machine or on the left. Consequently, means are provided for operating the yokes in the sequential manner above described, these means comprising a cam-roller 151 and adapted to be engaged by a cam-plate 152 on the slide 124 for the purpose of throwing the yoke Y, or more particularly, the arm 143 thereof outwardly and against the action of a spring 153 attached to a stud 154 carried by the am 142 of the yoke Y, so as to insure the retraction of the latter, to-

gether with the presser P before the plunger descends. In order to retract the yoke Y when the nippcrs cooperate with the pile of labels at the left hand side of the machine. the slide 124 is provided with a cam 15? adapted to ride over a roller carried on an arm 156 which is pivoted at 157 on a stationary bracket attached to the bed of the machine and the free end of which is connected by a link 158 with an arm 15!) forming a part of the yoke-arm 143. \Vhile the right hand presser is thus taken care of, the left hand presser connected with the yoke Y is actuated directly from the plunger as clearly shown in Fig. 5. in which the yoke Y has a side extension 160 to which is articulated the upper end of a rod 161 which carries a collar 1G2 adjustably held thereon and adapted to have its underside engaged by a hunter 163 carried by the tie 164 where by the guide rods 47 of the plunger are connected at their lower ends. Suflicient clearance is left between the hunters 1G3 and the underside of the collar 162, so that the plunger may rise sufficiently to clear the presser P of the yoke Y as the latter is swung inwardly and follows up the presser I as the latter retracts to its outward position. A spring 165 cooperates in returning the yoke Y to its outer position.

The operation of the machine is as follows: A suflicient quantity of blank-labels B and B being disposed within the holders at the opposite ends of the machine. the rotation of the shaft 30 (see Fig. 1) will re sult in moving the right hand gumming slide to bring the pads 92 thereof directly over the blank-pile B which then is caused to ascend by its raising-spring 91 to bring the uppermost label into contact with the gumming pads. The table 89 is then again slightly depressed leaving the blank-label attached to these pads so that then the nipper- jaws 127 and 128 may first straddle the end of the label and at the final movement of the bar 68, nip the end of the blank whereupon the bar 68 is moved from right to left thus drawing the label across the upper open end of the retainer or chute R. During this time the plunger has been in its highest position and the pusher 35 has pushed the lowermost box in the hopper into the plunger, it being understood. however, that preferably all the boxes are placed in the hopper bottom side up so that the la.- bel will be gummed to the bottom of the box. The plunger will now descend bringing the box into engagement with the top surface of the flat lying label and push said box into the receiver R thus partially folding both ends of the label around the side edges of the box which latter will now be frictionally held within the retainer and released from the plunger by virtue of the movement of the clapper. The plunger now rises and the right hand yoke Y will then be swung with its presser toward the left thus folding the right hand end of the label over the box and pressing the gummed surface thereof into cohesive contact therewith. As soon as the yoke Y returns to its normal position, the yoke Y is swung with its presser P inwardly to fold the left hand end of the label around the left edge of the box and subsequently bring the gummed end to overlap and into contact with the gummed right hand label end already on the box. The yoke Y then returns, and the picker-bar 68, which in the meantime has rested in its left hand position as shown in Fig. 5, will now take a label from the left hand pile B which has been operated in the same manner as the pile B previously mentioned. and the action of the plungerand the folders is then repeated as before, it being understood that each downward movement of the plunger will deposit another box into the retainer which is adapted to hold a number of boxes so that each box freshly entering the retainer will serve as a means for pressing the freshly gummed label of the preceding box firmly into place thereon, so that when the box finally emerges from the bottom of the retainer. the gum of the label is practically set and dried.

It is, of course, obvious that the feeding-in mechanism can take place comparatively rapidly and without experiencing any difficulty of the operation either of its own mechanism or of that of the plunger, the speed of the latter being practically controlled by the speed with which labels can be positioned beneath the plunger. By incorporating in a machine of this character two piles of labels disposed at opposite ends of the machine and by providing a single mechanism whereby blank-labels will be taken from said piles, respectively, in an alternate manner. or in other words first from one pile and then from the other pile, it clearly follows that the capacity of the machine will be greatly enhanced. doubled as against that of my former machine above referred to.

Many changes may be made in the construction and organization of the several compcnent parts and mechanisms of the ma chine without departing from the spirit of the invention, and I wish it to be distinctly understood that I do not confine myself to the particular construction and organization of the nipper mechanism above described, or to the means whereby the blanletablcs are actuated to bring the blank-labels into position to be nipped and carried into place.
