In general; the present invention contemplates a labeling t machine havingnovel label wiping apparatus "for wipingaZ-labelabout the'conical ,surfaceof thetapere'd neck of a bottle ina novel manner such as toprovide a-true rolling contact against the conical-surfacewhereby'to eiT-ect a uniform wiping: pressure 7 about the-conical surface. 'i Inf-the illustrated embodiment of'the inevention the wiping member comprises a tapered roller. or" -frustrum of. a cone-arranged to engage the 'surfac-e' of' the tapered neck-of the hottle which has the generalshape -of -a frustum-f a cone, and provisionis made for moving the roller through an arcuate -or circularpath in an inclined'position about the verticar axis of-'-the bottle with "the. extended center i line or axis pf the :roller and theaxis of the bott1e having a common apex, the-*motion being equivalent to the rollingcontactof ''-two right -cones orthe 'frusta of cones'zhaving a'common-apex.

Referring now to the drawings, theinvention is, fer :purposes'sof illustratiom herein-shown" as embodied a lab'eling machineof a known type now upon themarketand whichis providedwith an intermittently operated-conveyor ii] arrangedto support and. move the containers 12 in uniformly spaced relation forpresentation-in operative position to successive -of-various labelingmechanisms disposed along thesides of the conveyer. Reierence -is -made-to the patent to C. SJWeksgNo. 1,425,351, dated August '8, 1922, as disclosing the general details of construction and mode v of operation of suchprior-art labeling machines. Inasmuchassmanyportions of the labeling machine of themselves constitute no part or" the present invention,=it h'asbeendeemed sufficient to herein illustrate and describe only .suchportions as will enable the:invention to be understood.

*Thezrillustrated-container 12 comprises a taperedneck bottleto :Whicn-are1atively narrow label it is supplied. Referringto l ig. 1, in the illustratedalabeling machine, abottle is first presentedto tan" adhesive applyingmechanism, indicated t generally at 16, arranged to apply a film ofadhesive l8 about one side of'the tapered neck of the bottle. 'The-adhesive applying mechanism It comprises a'ifle'xible glue pad 20 mounted on a: yieldableflinkage= 22 carried by a reciprocatoryibar 24. 1 In: its retracted position, the padiw is presented flatrin-ialignmentwith a vertically reciprocalitransfer roller. :25 arranged to be elevated into. engagement withithe glue *pad to transfer. a. coating of adhesive thereto in the usuahmanner.

Upper guide rails i30,2%32"may "alsoberprovided"for en- ;gagement'lwith'. the uppersen'ds. of the. bottles, as shown.

The reciprocating bar '24 is arranged to be reeiprocat'ed in timed relation to the movement 'of the intermittentlyoperated conveyer byany well-known mechanism suchas that disclosed'in the Weeks patentabove referred-to, and, the

bottle thus provided with a film of adhesive IS on one side of the tapered neck, is subsequently presented to a label applying station, indicated generally at 34, which includes a label box or magazine 35 mounted and operated in a manner for effecting the application of labels directly from the label magazine to the surface of the bottle. The label magazine is carried by a reciprocatory bar 38 arranged to move in a path transversely to the line of movement of the bottles. The labels l4 carried in the magazine 35 are arcuate in form, as illustrated in Fig. 7, and shaped to conform to a developed portion of the conical surface to which the label is to be applied.

Cooperating with the label magazine is a second reciprocatory adhesive applying device, in-

dicated generally at 45 disposed on the opposite side of the conveyor 10. The adhesive applying device 48 comprises an open U-shaped frame.

42 carried by a reciprocatory bar G4 and the frame is provided with laterally extended pads 46, 48 at the free ends of the legs of the U-shaped frame arranged to straddle the neck of the bottle when in its forwardly extended position. In its retracted position, the pads it, 48 are disposed in alignment with a vertically reciprocal transfer roller 5!] arranged to supply the pads with adhesive, and, in its forwardly extended or advanced position the pads are arranged to engage the ends of the label in the magazine while the latter is in engagement with the neck of the bottle. 7

Thus, in the operation of the machine, the magazine is advanced to present the foremost label in the magazine against the adhesive coated portion #8 of the tapered neck of the bottle and while thus disposed the adhesive applying pads 46, 48 are advanced and pressed against the laterally extendedends of the label to apply a film of adhesive to the same. Thereafter the magazine is retracted effecting withdrawal of the foremost label therefrom and upon retraction of the pads 46, 48 the label remains attached to the adhesive film !8 of the bottle and partly wrapped about the neck.

At the following station of operation, indicated generally at 52, the attached label is pressed or wiped against one side of the bottle by an arcuate and yieldingly mounted presser member 54 carried by a reciprocatory bar 56 to present the extended ends 69, {B2 of the label substantially parallel to one another, the label taking the form of a U in plan, as illustrated in Fig. 1, preparatory to being wiped about the remaining side of the tapered neck of the bottle. The presser member 54 may and preferably will be shaped to conform to the tapered section of the bottle against which it is pressed.

At the two next succeeding stations of operation, indicated generally at 58, 6B, the extended ends :80, N32 of the label are successively wiped into engagement with the remaining side of the bottle neck and preferably in overlapping relation as illustrated. Each wiping mechanism 58, 5B is similar in construction and mode of operation, each being provided with a conical wiping roller 62 mounted in an inclined position and which is caused to follow an arcuate path about the axis of the bottle and against the tapered neck thereof to perform the wiping operation. In operation, at the time the first extended end 408 of the label is being wiped by the first mechanism 58, the other extended end E82 of a preceding bottle is being wiped into overlapping relation with the first wiped extended end by the simultaneously operated mechanism 68. Since both mechanisms 58, so are identical except that they are arranged for left and right hand operation, it is believed that a description of one will suffice for both.

As best shown in Figs. 4 and 5, the wiping roller 62 comprises a frustum of a cone having an apex 64 in common with the apex of a cone formed by extension of the surface 66 of the tapered neck of the bottle. The roller 62 is rotatably mounted on an arm 58 with the roller axis H3 in an inclined position and passing through the apex 64 when the roller is in contact with the bottle neck. The mechanism illustrated is arranged to move the inclined roller 62 about the vertical axis 12 in a manner such that the axis '10 of the roller is swung or revolved in a conical path with the fixed apex E l as its center and the roller surface in engagement with the conical surface of the neck thus effecting a true rolling contact of the conical roller without slippage with relation to the conical surface of the tapered neck.

The conical wiping roller 62 is caused to follow a conical path about the neck of the bottle in an inclined position and with the roller at all times in contact with the surface of the neck of the bottle by compound or interconnected parallel linkages indicated generally at M and 76. As herein shown the roll carrying arm 68 comprises one arm of a right angle or 90 bell crank, the second arm 78 of which forms one parallel arm of the parallel linkage T4. The parallel linkage 14 includes a second parallel arm 80, a relatively fixed link 82 in which the parallel arms 18, 8B are pivoted at 84, 85 respectively, and a parallel link 88 connecting the ends of the arms I8, 80.

The parallel linkage I4 is interconnected with the second parallel linkage 16 carried by a rockingly mounted supporting arm 93 pivoted on a vertical shaft 92. As illustrated in Fig. 2 the vertical shaft 92 is journaled in a bracket 93 attached to the platen 95 of the machine frame. The second parallel linkage includes

parallel arms

94, 96 pivotally mounted at relatively fixed pivots I04, I 06 respectively in the supporting arm and a parallel link I08 connecting the

arms

94, 96. As clearly shown in Fig. 4, the parallel arm 94 of the linkage 16 is formed integrally with the parallel arm as of the linkage l4 and forming a right angle bell crank therewith havmg its pivot at 86, and, the parallel connecting link I08 of the linkage T6 is formed integrally with the relatively fixed parallel link 82 of the linkage l4 and likewise forming therewith a right angle bell crank also having its pivot at 86.

From the description thus far it will be seen that the compound parallel linkages l4, 76 are supported by the arm 90 on the shaft 92 and, as herein shown, provision is made for rocking the arm 90 to move the wiping roller 62 and its associated linkages into and out of operative relation to the bottle. As shown in Fig. 2, the arm 90 is arranged to be rocked by a cam H0 mounted fast on a cam shaft H2 forming a part of the labeling machine and through connections including a roller H4 carried by a lever H9 pivotally mounted at H8. The lever H5 is connected by a link E20 to one arm I22 of a twoarmed lever fast on a rocker shaft I24, the second arm I26 being connected by a link I28 to the supporting arm 90.

Provision is made for rocking the compound linkages l4, F6 to effect the arcuate movement of means for supporting and intermittently convey lng tapered neck bottles in definite spaced relation through successive operation stations of the machine, means for attaching a label to a portion of the conical neck surfaces of successive bottles with the ends of the labels extending substantially parallel to each other, wiping means disposed at one station of operation for wiping one of said extended ends about said conical surface, and wiping means disposed at a succeeding station of operation for Wiping the remaining extended end about the remainder of the conical neck, said wiping means being arranged for left hand and right hand operation respectively.
