LABELING MACHINE Filed April 8, 1927 5 Sheets-Sheet 5 B 3718 fl/lorng Patented Feb. 11, 1930 STTES OTTO GEORGE BRAUTIGAM, OF JERSEY CITY, NEW JERSEY, ASSIGNOR TO MCDONALD EIIGINEEEING CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK LABELENG MACHINE Application filed. April 8,

This invention is a labeling machine designed with particular reference to the application and affixing of labels or strips of paper or cloth to one or more adjacent surfaces of an article where extraordinary precision is required and where th delicate nature of the article or its covering must not be damaged by ordinary machine handling.

Themachine particularly described herein is designed specifically with reference to accurately applying and aiiixing a narrow strip of edging on adjacent sides of the article in such a way that the pattern or design on the labeling strip will match other strips on the adjacent sides and corners of the article and further to effect the transfer of the article from one operating station on the machine to another operating station without marking the article while in transit, but it is to be understood that the invention is not restricted to the application of one strip to two adjacent sides of the article for the reason that the invention may be used in applying and affixing strips or labels to'two or more corners or adjacent sides simultaneously.

Briefly stated, the object of the invention is to provide a safe transfer of the article from the supply conveyor belt to the article transfer support by a new and useful device for preventing the flexible pusher from contacting with the article before it is in direct line with the article support, and to further protect the article in transit upon supports without friction upon the article, and at the same time prevent the article from advancing beyond he work performing stations along the line of travel of the article, and also to reposition the-several articles before their respective work performing stations, which in turn are a gumming mechanism for applying adhesive to one or more surfaces of the article, a labeling mechanism for applying a label or strip of material upon all or a part of the gummed surface of the article, a labeliping mechanism, and a label-affixing and smoothing down mechanism, all working in timed relation to each other but operated independently. Said gumming, label-applying, and label-wiping mechanisms are locater adjacent to and parallel with the article sup} 1927. Serial No. 181,955.

port and are operated on reciprocating carapplication applies a label in the form of a strip to the corner or adjacent sides of a rectangular shaped article by first applying gum to one or more surfaces of the article by gummingmechanism, then the article is advanced in a step by step movement along a support to another position to receive a label or strip on one of said surfaces from a magazine containing a pack or stack of labels and thereafter proceeds with the strip adhering thereto, to another position to be folded over and affixed to both gummed surfaces and thereafter further smoothed down on the said surfaces by means such as rollers during the continued movement of the article along'the support.

A particular feature of the invention comprises a plurality of gumming members for applying adhesive toa plurality of surfaces of an article which in their rearward position on the carrier slide'assume an open flat plane posit-ion adaptable to receive an application of gum from a gum transfer member plying between them and a gum supply means and which in their forward position come in contact with an article to deposit gum on one or more sides of the article. The gumming members being pivotably hin ed with relation to each other so that upon contact with the article to apply gum thereto, one member actuates the other member, or the hinged gumming member may be actuated by other and separate means upon contact with the article, and in either event the gumming members being so spring balanced that upon breaking contact with the article or such other contactmeans, the gumming members assume their normal flat plane position.v

A further objectis tol provide a label retaining magazine from the open or delivery end of which the foremost label may be withdrawn without hinderance from retaining means and applied for its full length or width to an article upon contacting with the article as the magazine mounted upon a reciprocating slide advances toward the article.

A further object is to provide means for affixing or wiping the labels securely and smoothly upon one or more surfaces of the article comprising a plurality of yieldable wiping members mounted upon a reciprocating slide which in its forward position permits one wiping member to contact with and press the partially affixed label on one surface of the article thereby affixing it and at the same ti'me'hold it securely while another wipin'g member bends the label and applies it to another surface of the article; said first member being yieldably mounted to allow the second member to advance untilsuitable means lifts it from the label as the slide recedes from the article at the end of which stroke the said second wiping member is reset.

A still further object'is to provide a finishing and smoothing down operation of the labels during the propelling of the articles from the label aflixing station to the delivery of the articles from the support.

A still further object is the provision of means whereby the articles are repositioned on the support with respect to the operating slides tobr-ing the articles-to perfect alignmen't therewith when the slides are in the -work performing positions.

A still further object is the provision of means to hold the articles under tension with relation to thesupport after the feed bar has positioned the articles in the work'performin'gpositions.

support bythesupply feed belt, thepusher 'will'yield with relation to-the bar and prevent'breaking of the moving parts and damage to the article and further to provide m'eans'to lock the pusher against movement with the feedbar when there is no article fed i'n-front thereof or an article-only partially moved before .it.

A- further object of the invetnion is to provide means whereby finished articles-such as them iat" thedifienentstations.

.As shown in the drawings the machine is provided with a table 1 supported on standards-2 and 3, above which a four way motion-feed bar is located operable between the article supporting members extending lengthwise of: the table and upon which the articles'to beopera tcd upon are dvanccd step by step bythe feed bar from station to station located adj aoent to and along one or both on the feed belt 33 to lie against a stop face with the feed bar 15, should there be no article 49 of an article guide rail, in readiness to be moved forward by the feed bar, this being one rail of a pair of guide rails to guide the articles along the support rails 2121, the rail forming at this point a stop member for the articles as they move to position on the supportby the feed belt before entering the work stations along the support- The coupling shaft 45, also running with this drive, will keep the gum supply reservoir in motion when the shaft 4 is stopped, preventing the drying of the gum coated parts during stopping periods.

The feed bar 15 at the front end of the machine, as best seen in Figures 1, 1 2 and 19, is yieldingly connected with a supplemental slide member 50. Normally this slide is moved in unison with the feed bar 15 in the longitudinal direction but does not have the lifting and lowering movement as does the bar 15. This slide is carried in an extended partabove the bar 15 of the slide frame provided for the slide 17. The slide 50 as stated. slides withe the bar 15 and overhangs rearwardly the bar 15, a stop 51 reaching down from the slide 50 and engaging the end of the bar 15 and being held thereto by a spring 52 of considerable length, this spring being attached at one end to the stop 51 and at the other end to the bar.

Fastened to the top of the slide 50 is a pusher member 53 in the form of a right angle plate, one part of which as 54 engages with the end portion of an article as the pusher is brought forward with the feed bar, to push the article fed in front thereof from the feed of the angle plate 53 and of such length to lie in front of the articles functions to pre vent the feed forward of the articles as they feed forward on the belt 33, until the full return of the pusher with the feed bar, at which time the next article is moved in front of the plate, see Fig. 1

Should, for any reason at this point, the feed of the articles be prevented to properly ride into the feeding forward position, and

' thereby obstruct the forward action of the the pusher against its forward movement fed in front thereof, or an article only partially fedin front. This is accomplished by a locking member in the form of a swinging pawl 54 mounted to lie in the path of the articles, and in front of the face 54 of the pusher. Normally this pawl hangs downward from a bracket 54, held on the guide rail against which the articles stop, with its lower end to lie in front of the pusher so that the forward motion of the pusher is prevented unless the pawl is lifted. This is done by the article as it advances to the stop 49, the article lifting the pawl free of the front face 54 of the pusher at about the time the article is well in position in front thereof and nearing the stop-49, the pawl then riding in this lifted position as the pusher is movng forward and backward on the edge 54 of the plate 53 until the full return of the pusher, when it will again drop in front to be again lifted by the article to face the pusher. (See Figs. 1, 1, 2, 3 and 19.)

Bythis construction of the pusher mechanism it will be seen, when the articles are not being fed the pusher is held against movement and when an article is jammed and not fully in front of the pusher the pawl will not have been lifted, and the pawl will hold the pusher, instead of the article taking this jammed strain of the pusher, and further when the article generally reaches the position in which the pawl is lifted the article is more often in its perfect travel position against the stop 49 to be pushed forward resulting in the pusher being checked by the pawl rather than the article in this restrained action of the pusher.

The articles, indicated in a general way by 56, are moved as just stated, by the feed bar and projections thereon, successively to the work performing stations along the support, the'first stop being a station where an adhesive substance is applied to the article. For some classes of work other operations may be performed before applying adhesive to an article. The description as here outlined is merely an example of the class of work performed by the machine. The machine is to some extent adjustable to suit articles of different form, size, etc.

At this first station the article shown at 56 is acted upon by a gumming mechanism designated by G, comprising a slide movable to and from the article at this station, mounted in a supporting bracket 57. The slide 58 is operated by a drum cam 58 on shaft 4 operating a rock shaft 59 by an arm 60 and roller 61 riding in a cam groove 62 of the cam. The shaft has an arm 63 and a link 64 forming a connection with an adjustable arm 65 by means of which the stroke of the slide may be regulated. The arm 65 is mounted on a shaft 66 in a bearing of the slide supporting frame 57. At the top of sides of the article support. As herein shown the articles are fed from any suitable source of supply on a belt located at one end and transverse to the article support, bringing the articles into position in line with the support and moved forward onto the support by a pusher bar which is held inoperable by a lock until the article is fed in and against the stop, thus preventing damage to the article or the machine. The article is then acted upon for further advancement by the feed bar to locate it in position at the first work station where the centering or repositioning device places the article exactly in a line with the gumming mechanism for an application of adhesive in a predetermined spot or spots on one or more adjacent surfaces of the article and at one or both sides of the article support as may be required.

As herein shown one side only is used for the class of work illustrated, but a duplicate gumming mechanism may be positioned in opposing relation for applying adhesive simultaneously to two sides of the article and their adjacent sides.

Upon further advancement of the gummed article by the feed bar to the label-applying mechanism, a label or strip is applied to the one gummed surface after the repositioning or centering device has positioned the article for receiving the label or strip in correct re lation to the gummed surface of the article for the purpose of obtaining correct registration, and upon further movement of the partially labeled article to the next station or label-wiping mechanism, and after again repositioning the article by the fingers, the label or strip is entirely applied to the article by the advancing wiping members. A further advancement of the article by the feed bar forces the labeled article under and between opposing and adjacent rolls comprising the label afiixing and smoothing down means.

A cam shaft 4, running lengthwise of the machine and suitably supported in bearings 4 under the table, and is driven by a motor 5, having a pinion 6, on its shaft meshing with a spur gear 7, fast on a short shaft 8, a clutch sleeve 8 also fixed to the shaft having a slidable part being one member of a clutch 9, for cngagemen't'with a companion clutch member, the latter an extension of a gear 10, loose on the short shaft 8. This shaft is supported in front of and in line with shaft 4, for rotation in bearing 11, the gear 10 meshes with a gear 12 on the shaft 4; by this means the shaft 4 is driven. A hand lever 13, having operatingconnections with the clutch 9 functions to stop and start the machine. The main shaft 4 has a cam 14 at each end of the shaft that controls the lifting and lowering of the article feed bar 15, which bar has projections 16 spaced apart to suit the length of the articles being fed along supporting rails.

The bar is supported at each end of the table on slide members 17-17, the lower ends of which are provided with cam rolls 18-18 to coact with the cams 14. The

slides

17 and 17 are mounted in vertically disposed guides 19-19 attached to the table at the top ends, and at the lower ends to the bearings 4-4. The top ends of the slides are provided with headed ends 2020 and fitted with open end T-slots for the feed bar to slide in, for longitudinal movement of the bar, and thereby provide a four-way movement to the bar by means of which the articles are moved along the support rails 2121. The longitudinal movement is given the feed bar by a cam 22 on shaft 4, by a cam rod 23, one end having a connection with the cam, and the other end to a double end rock arm 24 fast on a rock shaft 25. The upper arm 26 of the rocker is connected to a bell crank lever 27 by a uni versal link connection 28 to an adjustable stud 29 in a slotted part of the arm 27 of the bell crank. The other arm 30 also has a universal link connection 31 with a link 32 which is adjustably pivoted to the feed bar 15 at 32. By means of the universal connections and the cam 14 the feed bar is free to move in all directions to provide the fourway action of the same. The support rails 21 and 21 which extend the entire length of the table, are cut out at the article receiving end to make room for a transverse feed belt 33, the top of which is of a height to be approximately in line with the top of the support rails. This belt is mounted on a suitable supporting frame 34, having at its outer end an idler take-up pulley 35 in an adjustable bracket to tighten the belt. The supporting frame is also provided with guide rails 36 to guide the articles on the belt to the rail supports. The belt is driven by a sprocket chain 37 by a sprocket 38 on the short shaft 8, the sprocket chain passing up to the rear of the machine over a sprocket 39 on a shaft 40 in a bracket 41 on which is also the driving pulley 42 of the belt 33, the sprocket chain continuing on under an idler pulley 43 to bring this part of the chain lower at this point to clear the support rails and pass along to a bracket 44, in which is mounted a coupling shaft 45 with a sprocket 46 at one end over which the chain passes and again joins with the drive sprocket 38. The coupling shaft 45 has a coupling 47 by means of which connection is made with a gum supply reservoir 48 hereinafter described.

By'this means it will be seen, when the motor is started, the feed belt 33 will also run together with the coupling shaft 45, but the shaft 4 will run only when the lever 13 is moved to cause the clutch 9 to engage with the loose gear 10, which becomes fixed to the shaft 8 and thereby drives the gear 12 of the shaft 4. It being the purpose of this drive to keep the articles crowding forward the shaft 66 an arm 67 having a bifurcated end 68, and slidably connected with a square headed rotatable pivot member 69 by means of which the slide is actuated.

Mounted on an upright bracket 70 for up and down adjustment on the side is a bracket 71 having extended portions 7 2 at each side thereof to slidably and yieldingly support a pair of gummer sections 73 and 7 8, the section 73 in the form of a cross bar 74 having fixed thereto slide rods 75 adjacent to each end thereof to slide in the extended side portions 72 of the bracket 71 in bearings 72 at the front and rear ends of these extensions. Between the bearings 72', collars 76 are fastened on the shafts and by springs 77 the cross bar is held forward, the collars 76 serving as stops when engaging the front bearings. This is clearly shown in Figs. 5 to 9.

The section 7 3 which is the upper section, is movable relative to the lower section 73 by a sort of hinge connection enabling this section to be tilted over as in Fig. 7.

One fixed part of this hinge as 78, and shown in duplicate together with its oompanion parts, is attached one at each end to the cross bar by screws 79. This hinge part has studs 80 reaching outward, the axis of which coincides with the corner of the article acted upon when contact is made therewith. These studs enter apertures in extended end members 81 fast on a similar cross bar 82 of the section 73. The parts 81 reach upward from the studs to provide a point of connection acting as a crank arm and have at this point studs 83 for one end of spring controlled links 84 attachable to the studs 83. The links are slotted and slidably carried at a point about midway of the link on studs 85 that are fixed to arms 86 supported on the bracket 71. These studs 85 extendoutward to support the links, and inward to form a hook to hold the ends of springs 87. The other ends of the springs are likewise attached to studs 88 carried on the extreme ends of the links 84. By these springs the links are held forward as will be noted and would tend to turn over the section 73' on its pivot. This however is prevented by the end of the slotted porti0n'84 of the links. This is true when the sections are withdrawn from the contact position with the article as seen in Fig. 5. The lower section 73 being fully forward against the stop collars 76, draws the links to the end of the slots 84 due to the springs 77 being more powerful than the springs 87, thereby holding the sections 73 folded back, bringing the both faces 90 of the sections in an open fiat plane position. These faces 90 are the contact faces of rubber pads 91 of the sections 73 and 7 3'. Preferably the rubber pads 91 are attached to be readily removable together with metal angle strips 92. These angle strips and pads are adjustable on the cross bars of the sections by screws 93 in open end slots 94 in the angle strips.

From the foregoing it will be seen that the slide, together with the gummer sections, is reciprocated by the rock arm to and away from the article at this station, carrying the

sections

73 and 73 in one stroke thereof into contact with the article. As seen in Fig. 6, the section 73 has just reached the article on the forward stroke and further forward motion of the slide will move the section 73 rearward on the bracket 71 against the spring pressure of the spring 77 as in Fig. 7. The links 84 are now free to move forward by the springs 87 since the pressure is relieved on the links 84, and permit the springs 87 to turn the section 73 over to assume the right angle position with its face 90 contacting with the top of the article. By this construction the contact against the article by both sections is a direct one, and not a sliding motion over the surface of the article to apply the adhesive thereto.

As will be seen in Fig. 6, in broken lines, a separate means may be employed to take the greater part of the pressure when the pads are contacting with the article, by providing an adjustable contact arm 89 to co-act with a projection 89 on the cross bar 74, so positioned to simultaneously engage with the pads, to prevent the spring of the article, in case the article is of a flexible material.

The adhesive is applied to the faces of the rubber pads when the slide is in its full retracted position, at which time the faces of the pads are in their flat open position, as before described. The usual well known means are provided to apply the adhesive to these faces; as shown the gum reservoir 48 located on the table 1 and under the open housing of the gummer slide, for ready removal of the same, for cleaning or other purposes and is for this reason connected to the drive coupling member 47 of the shaft and return to the roll of the reservoir to receive a fresh supply of the gum, as will be understood. The transfer roller 97 is carried on a pair of arms in the form of links 99, having bearings at the top ends to support the shaft ends for rotation therein of the transfer roller. The links are pivotally carried by a bifurcated carrier arm 100, one end fulcrumed on the shaft 25 and lying over the cam shaft 4 to engage a cam 101 to lift the carrier by a roll 102 at the center portion of the carrier, the front ends carrying the links 99 which are held to a forward tension by springs 103 against the guide bars to guide the transfer roller which is provided at each end with a flanged collar to guide the links endwise as well as to control the roller in this endwise manner, to ride up and down on the tracklike guide bars 98.

Having just described the manner in which the gum is supplied to the several surfaces of the article at this gummer station, the article is ready to be moved forward by the feed bar to the next stat-ion. Before reaching this station however, anintermediate stop is made to provide the room for the mechanism of the gummer and the next work stat-ion. At this next station the article is shown at 56 to be supplied with a label from a label magazine 105. The label magazine is mounted on a slide 106 for reciprocation to and from the article, and the slide is controlled in this movement by a link connection to the rocker shaft 66, of the gummer mechanism, from which shaft an arm 107, offset from the adjustable arm 65, connects with this link 108, and is pivoted to this arm at one end and making an adjustable connection with its other end with a stud 109 movable in a slot of an arm 110 on a rock shaft 111, located in bearings, one in the magazine slide frame and one under the table. At the top of the shaft 111 is an arm 112 connectd in a similar manner to that of the arm 67 which, moves the slide and the magazine therewith. As stated, the s'lotted portion of the arm 110 will allow the slide stroke adjustment by movinig the stud 109 along the slotand by this means regulate the slide stroke and the front end of the magazinemay be brought to engage the article with more or less compression.

The magazine,the front portion of which is shown in Figs. 10 and 21, is provided with a base plate 113 which may be attached to the top of the slide 106 in any suitable manner.

Fastened to this plateare adjustable side members 114, in the form of angle strips, having slotted portions for screws 115 passing through the slots into the base plate. Between these side members the labels are positioned, to be urged forward bya spring pressed plunger bar 116 in the usual manner, movingv the labels to the open end of the magazine. The side members are provided with stops 117 near the upper ends only, to engage to top ends of the labels. This is for the purpose of making contact with the article by the label free of any stop members with the full length of'the label, the lower portion of the label making contact with the upper portion of the article, about one half of the height of the label being applied to the gummed surface, this being the lower portion of the label as clearly seen in Fig. 10. In this view the magazine is shown as being retractedjnst after havinig applied the label to the gummed surface. The labels are held down to the plate 113 by a pair of pivoted swinging members 118 to exert a slight pressure to the top of the labels, but permitting free forward action, and thereby prevent the shifting of the same out of alignment. The front ends of these bars are each provided with a stop 119. hen refilling the magazine with labels the bars are tilted back on the pivots120 in slotted blocks 121 fast on a cross bar 122, a bearing in which also guides the plunger rod 116. To prevent the labels dropping downward from the front end of the plate 113 on which the labels rest, a pair of overhanging sliding supports are provided. These slides are best seen in Fig. 21 and comprise dovetail slides 123 fitted to slide in dovetail recesses 124 in the base plate. Springs 125 hold the slides forward to a stop 126 so the slides extend beyond the pack of labels a short distance and in this manner support them. When the magazine contacts with the article the slide members will move rearward to allow a perfect contact of the label with the articie. It will be noted by this construction the label is not obstructed by any holding or stop members at this contact portion and free to be attached to the previously gummed surface of the article.

The article is now moved to the next station with the overhanging label attached, to be firmly affixed to the side of the article by a presser pad 130 and the label folded over on an adjacent side of the article by an advancing roller action to likewise a'liix the label to said adjacent side, the roller 131 being brought into action by the yielding movement of the pad and a means is provided to lift the roller free of the label and article after the completion of the label rolling action and withdrawn from the article in this lifted position. The article indicated at 56 at this station (see Figs. 1 and 2) is acted upon by a mechanism carrying the pad and roller which is mounted on a slide 132 to be actuated to and from the article in timed relation by a cam 133 on the shaft 4 through a cam roll 134 on an arm 135 fixed to a vertical rock shaft 136 housed in a suitable bearing 137 depending from the table. At the top of this hearing and the shaftend above the table is an arm 138. A link 139 pivoted to the arm which reaches forward, passing under the frame 140 of the slide 132 to connect with an adjustable stud 141 in a slotted portion 142 at the rear of the slide. By this means the slide is actuated, the cam roll is held to the cam by a spring 143 attached to the arm 138 and a pin 144 on the table.

The slide 132 carries an upright bracket 145 held thereon by bolts 146 which provides a supoprt for a bracket 147 which may be adjusted up and down on the upright bracket and held in such position by bolts 148. This bracket has extended side portions 149 similar to that previously described for the bracket 71, and each side portion has bearings 150 at the front and 151 at the rear for slide rods 152, the front ends of which are fixed to a cross bar 153 to which the label affixing pad 130 before referred to, is attached and when contact with the article is made by this pad 130 the cross bar 153 will be pressed rearward against springs 154: positioned on the rods between a collar 155 and the bearings 151. As this pad moves rearward under this spring pressure the roller 131 will ride over the top of the article as seen in Fig. 12.

The roller 131 is carried on a bar 156 with bearings extending forward therefrom to support the roller for rotation on the shaft ends of the roller and the bar is fixed to the front end of swinging frame 157, the other end of the frame terminating in arms 158 having a pivotal connect-ion with pivots 159 in the bracket 1 17. The roller by this con struction may be lifted and lowered, being controlled by a cam slide 160 riding in a recess 161 in the center of the bracket 1 17 about midway of and under the swinging frame 157 at which point the slide engages a cam roll 162 carried in an adjustable block 163 held in a slotted extension by a bolt 16% for the desired adjustment. The slide has a raised and a low portion and is shiftable forward and backward. The frame 157 is held down by a pair of springs 165 located between headed studs 166 and the top of the frame 157, the studs passing through loose apertures in the frame and the lower ends of the studs threaded in the bracket 1 17. By this spring means the cam slide is normally under tension and likewise the roller 131 when in position on the article as in Fig. 12. As before stated the pad 130 and the cross bar both forced rearward, will ride the roller 131 over the label on the article, this being due to the forward motion of the slide 132. The continued forward motion of the slide will bring the inner face of the cross bar 153 in contact with a pin 167 depending from the cam slide 160 carrying this slide rearward and by reason of the raised portion thereof lift the swinging frame 157 together with the roller 131 free of the label.

The slide 132 will now be retracted from the article, bringing back the cam slide 160, and at about the time the cross bar 153 under its spring pressure reaches its normal position, which is when the collars 154: reach the bearings 150, the pin 167 of the cam slide will engage the bent end of a cam slide resetting by

separate contact parts

130 and 130*, as seen in Fig. 13. I

The articles with the labels attached as just stated, now move along the support rails 21 and 21 from this stat-ion, to be further acted upon by a smoothing androlling action, by top and side rollers, mounted on a bracket 169, on a rail 17 0' forming a partof the frame work at the top of the machine and extending from end to end thereof. This bracket 169, best seen in Figs. 15 and 16, is here shown as a short length of angle bar supported at each end by bent members 171 fixed to the top of the rail 170 and by depending portions support the angle bracket in such a osit-ion to bring the faces of a pair of rollers 172, a pair at each end of the angle bracket, so the faces thereof at right angles to each other will exert a pressure to the top and side respectively of-the label, as the article ismoved along the support rails to be discharged from the machine opposite each pair of the rollers 172 to provide a roller bearing surface for the articles as theypass the rollers 172 at this point to prevent friction as well as marking the articles by sliding contact with the guide rails, a roller 173, one for each pair of rolls 17 2 and directly opposite said rolls and preferably adj ustably mounted on a support 174 on movable spindles held in slotted portions of the support by a nut and washer, whereby the rollers may be adjusted to make a suit-' able pressure of the article against the face of the side roll of each pair, and the angle bracket 169 may be adjusted in a similar manner on the supports 171 to apply a top pressure to the article against the rolls on the rail 21 on which the article is supported.

The feed bar, when the machine is operated under a high speed, and especially when articles of considerable length and wei ht are propelled along the support, are caused to override their true stopping position along the work stations. Means are provided to obviate this diliiculty by providing friction rollers, that is, rollers mounted under a frictional tension, as seen in Figs; 2, 17 and 18. On the rail 170 preferably two such rollers are provided for each article at the stopping positions along the support and are rotatively carried on right angle levers 175 that are pivotably supported on the rail, as at 176 with one arm of the lever extending downward and carrying a roll 177 havin a rubber faced portion 17 8 suitably fastened to the outer part of a ball bearing member for smooth rota- :tion of the roller, and by the rubber facing provide a resilient contact with the article, the roller is held under a frictional tension by a washer 179 and spring 180 holding the roller against the side of the hub of the lever 175 against free rotation. The levers are held by a spring 181 attached to an upstanding arm of the lever to a hook on the rail holding the lever to a stop 182 against the top of the rail, which places the roller, in such a posi tion to be li ted free of the stop when the article is under the roller as seen in Fig. 2, as the articles are advanced step by steppassing under these rollers which are bearing downward by the spring 181, and when the articles come to the stopping position are prevented from over-riding this position by the rollers 177 that are under tension by the spring 180.

By this means the articles are brought successively to comparatively uniform stopped locations at the work stations.

To further aid the rollers 177 an additional roller 183, mounted on a guide rail 18%, is of a similar construction to the roll 177, one provided for each work station and located central of the article to bear on the top thereof and to the rear of the rollers 177. These rolls also serve to hold the articles down on the support rail 21 and prevent the lifting or tilting of the article wl ile the work performing mechanisms of the work slides are brought forward to engage the articles as shown in Fig. 1.

Before the work slides begin their respective operations on the articles, means are provided to reposition the articles on the support, should the articles be stopped out of true alignment with the work slides. As shown, the

slides

106 and 132 are both pro vided with guide members. On the slide 132, these members are in the form of curved side arms 185 and are fastened in any desirable manner to travel with the slide. They are here shown attached to the cross bar 153 one at each end to extend forward therefrom to be advanced ahead of the work members of the slide to engage th sides of the article by their flaring curved ends to permit the entrance of the article to be repositioned between these members before the slide has reached its work performing position. The slide 108 is similarly provided with repositioning members as shown at 186, Fig. 1. In this case they are attached to the base 113.

The gumming mechanism carried by the slide 58 has the article repositioning means arranged reversely to that of the

slides

106 and 132 to position the article by a pair of side members 187 that swim into position the article by the side members has been made, and to thereby reposition the article.

Before the slide has made its full forward stroke, the side members 187 have engaged the article for their full length and until the shoulders 196 on the inner side of said members have contacted with the article to press it firmly against the front guide rail 197 thereby aligning it with the slide before the gummingpads apply adhesive to the article. The further forward movement of the slide is permitted by the elongated slot 194 in the link 191. This is best seen in Fig. 20.

The friction or tension rolls 178 and all other rolls along the work support, along which the articles are shifted, prevent the marking of the articles since such articles previously supplied with printed labels would transfer the inked surfaces along the guide members to be again transmitted to the articles. By this rolling actionthis is obviated.

It will be understood the invention is not limited to an article of box form presentin a right angle to which the label is aflixe Such article may have angular surfaces, such as hexagonal, octagonal or other shapes; also more than two sections for applying the adhesive to the article may be employed.

The particular work performed as here set forth, is to apply this strip or label over a hinge member of a cigar box, and as will be noted the label may serve as the hinge member, or the hinge member may be first applied by this machine and the articles run through the machine a secondtime to apply the label over the hinge. The label may be provided with a cloth facin to provide a double purpose of a durable hinge member as well as a label.
