9 Claims.

The .invention relates to labeling apparatus and more particularly to apparatus for use in the manual application of labels to the articles for which said labels'are designed.

The object of the invention is to provide an apparatus of the indicated type whereby the labels may be efiiciently applied to the articles in a simple and efficient manner and so as to locate successive labels in predetermined uniform, posi'tions on successive articles. The invention contemplates further an apparatus which may be utilized in connection with articles of varying surface contour and with labels of different designs and shapes, and Whichrequires no particuuar skill in its operation. I A

Other-more specific objects willappear from the description hereinafter and the features of novelty will be pointed out in the claims. In the accompanying drawings,; which illustrate examples of the invention without defining its limits, Fig. 1 is a plan view of the novel apparatus in one form; Fig. Ziska sectional elevation thereof on the line 22 of "Fig.1; Fig. 3 is a perspectiveyiew of a bearing bracket ineluded in the apparatus; Fig; 4 isfan enlarged detail sectional viewof a locking gm'eans embodied therein; Fig. 5 is a plan view of another form of the apparatus; Fig. 6 'is a cross-section on the line 6-6 of Fig. 5 Fig. 7 is a detail perspective view of a label positioning element included in the apparatus; Figs. 8 and 9 are perspective views respectively of two different forms of moistening devices;-Fig. 10 1s a plan view of still another form of the apparatus; Fig. ll is a longitudinal section on the line ll-ll of Fig. 10; and Figs. 12 and'l3 are fragmentary perspective views of the holders for the articles to :be

labeled. l

In its general construction, the apparatus comprises a-base l5 preferably carried by suitable supporting legs l6 and itself serving as a support for a table or top ll located at a distance above and in-vertical registry with the base I5. The

. table or top I! is maintained in place" by means of corner bolts 18 which pass through spacing sleeves l9 located between and in engagement The tableor top ll isprovided with are arranged in corresponding alined pairs in inclined relation to the slots 20 as shown in' Fig. l. The slots 20 and 2| are formed with shoulders 22 along opposite edges and at least one-end thereof for the purpose to be more fullysetforth hereinafter. I r I The apparatus further includes means for positioninga supply stack of labels 23 upon the table or top I! and for maintaining said-stack in place thereon during the labeling operations. The label positioning means' is shown in the form of guide members or pins 24 projecting upwardly through the slots 20 and 2| to define a label enclosure on the upper face of the tableor top ll. In order to accommodate labels 23 of vary-'- ing dimensions and different contours or shape and to permitthe position of the label enclosure and consequently the location of the stack of labels 23 on the table or top I! to be varied at will,- the guide members or pins 24' are so arranged that the position thereof insaid slots 20 and 2| may be selectively adjusted as required.

and 2! and slidably fitting the latter, washers 29 being located on the bolts 26 in engagement with thelower surfaces of said brackets 25 to provide bearing surfaces for the associated nuts 21. To

increase 'therange of adjustability of the guide pins or rods 24 thebrackets 25 may be formed with slots 30 for the accommodation of the bolts 26 asshown in Figs. 2 and 3. The heads of the bolts-26 do not project above the table or top u and preferably are flush with the upper surface thereof as shown in Fig. 2, so as not to interfer-e with the adjustment of other elements of the apparatus on said table or top ll. I In the-operation of applyingthelabels 23to the articles A for which said labels are designed, the guide pins 24-act as supports for said articles A and are depressible thereby to enablev the supported article A to be brought intocontact with the currentterminal label 23 'atpthe top of the supply stack. For this purpose-the brackets j 25 include depending bosses 3| in which the guide pins 24 are slidably mounted for vertical movementtherein;-- to permit the downward movements of said guide pins24 without interference, regardless of the positions occupied by the brackets'25, the base I5 is preferably provided with slots 32 in vertical registry with the slots 20 and 2| of the table or top H. In the preferred arrangement, the guide pins 24 are controlled by springs 33 which bear with one end against the base I5 and with the other end. engage projections on the pins or rods 24 as exemplified by the cotter pins 35; the latter, by contact with the lower ends of the bosses 3| serve also to arrest the upward movements ofthe pins or rods 24 under the influence of the springs 33.

In addition to the parts so far described, the

apparatus includes means for positioning the articles A in predetermined relation to the supply stack of labels 23 and for controlling the movements of the articles A in such predetermined relation to said stack to thereby definitely predetermine the location of successive labels 23 on successive articles A. Forillustrative and ide.- scriptive purposes and Without intent to define the operative limits of the apparatus, the articles A are exemplified by bottles, and the aforesaid positioning means is shown in a form arranged to co-operate therewith, and comprising a plurality of carriers 35 provided with slots 36 extending lengthwise thereof. The carriers 35 constitute supports for upright members 3'! preferably having relatively bevelled vertical edges 38 as shown in Fig. l. The carriers 35 are located in surface engagement with the upper face of the table or top and are selectively adjustable thereon to locate the upright members 31 in a manner to properly define the label receiving position of the bottles A or equivalent articles. In the illustrated example, the carriers 35 are controlled by bolts 39 projecting through the slots 36 and having preferably squared sections 49 slidably fitted in the slots 2| and heads 4| in engagement with the lower face of the table or top IT; with this arrangement the squared sections 40 in conjunction with the slots 2| maintainthe bolts 39 against rotation on their axes.

.Washers 42 are mounted on the bolts 39 in contact with the carriers 35 for clamping engagement by nuts 43 threaded on the bolts 39 as illustrated in Fig. 4.

y In utilizing the apparatus shown in Figs. 1 and 2, the bearing brackets 25 are shifted in directions to move the guide pins 24 lengthwise of the slots 20 and 2|; the various pins 24 are adjusted relatively to each other to define an enclosure for the particular labels 23 arranged in a supply stack and for locating said stack of labels 23 at a predetermined point of the top or table II. The brackets 25 may be clamped in place by tightening of the nuts 21 on the bolts 26 to therebyfix the guide pins 24 in position in the slots 20 and 2|; the stack of labels 23 may then be placed in an upright position in the enclosure defined, by said rods 24. Either at this stage or previously, the carriers 35 are manipulated to set onepair of upright members 31 in spaced parallel relation, to each other, and to set another pair of said upright members 31 in converging directions with the bevelled edges 38 in spaced parallel relation to each other as shown in Fig. 1. In the illustrated example, the distance between the opposite parallel members 31 corresponds to the outside transverse dimensions of the bodies of the bottles A to which the labels 23 are to be applied,

while the distance between the bevelled edges 38 is furthermore such that the bevelled edges 38 thereof provide abutments for the beads a customarily found on the necks of conventional bottles to thereby position the bodies of the bottles A in predetermined relation to the supply stack of labels 23.

In practice, if a stack of gummed labels 23 is used, the outer surface of the bottles A which is to receive the label is first moistened or dampened in any convenient manner; if the labels 23 in the supply stack are not gummed, a coating of adhesive is suitably applied to the outer surface of the bottle A. In any case the bottle A, either previously moistened or coated with adhesive, is

placed upon the upper ends of the guide members or pins 24 with the moistened or adhesive coated surface facing downwardly and with the body of said bottle A between the parallel upright members '31, and the neck thereof between the bevelled edges 38 of the converging upright members 3'! with the bead a in contact with said bevelled edges 38 as shown by dotted lines in Fig. 1. At this stage the bottle A accordingly is supported by the pins 24 with the body of said bottle above and in predetermined relation to the terminal label 23 at the upper end of the supply stack.

With the bottle A thus supported and positioned, a downward pressure is manually exerted thereon'which depresses the pins 24 in the bosses 3| against the tension of the springs 33 and thereby brings the moistened or gummed surface of said bottle A into surface engagement with the terminal label 23 which is at the top of the supply stack at the time. Subsequent to such contact, sufficient pressure is exerted on the bottle A to cause said terminal label 23 to adhere thereto after which said bottle A and attached label 23 is lifted from the apparatus; as this takes place, the springs 33 will restore the guide pins 24 to normal positions ready to receive and support the next bottle A to be labeled.

It will be noted that the spaced, parallel upright members 3'! extend lengthwise of the bottle A and thus provide guide surfaces for the latter in its vertical movements to pick up and remove a terminal label 23 from the supply stack; at. the same time, these members 3'! guide the bottle A in any lengthwise adjustment which maybe required to bring the bead a into contact with the bevelled edges 38 of the converging upright members 37. Successive bottles A may accordingly be speedily placed in. accurate label receiving position in the apparatus and labeled without requiring any special skill or time consuming effort or care on the part of the operator.

The apparatus shown in Figs. 5 and 6 corresponds essentially to the one illustrated in Figs. 1 and 2, and differs therefrom only in the character and operation of the means whereby a supply stack of labels 2% is positioned upon the table or top H. In the illustrated example, the positioning means includes guide members or pins 24 corresponding to the. guide members or pins 24 of the form first described, and similarly mounted for adjustment lengthwise of the two aligning slots 20 which extend longitudinally of the table or top ll. In addition to the guide pins 2 the positioning means includes guide members in the form of upright plates 44 preferably flaringv outwardly in opposite directions at their upper ends for instance by being curved as illustrated at 45 in Figs. Sand '7. The plates 44 are carriedrby members it pivotally attached at 47 to brackets 25, springs 48 being provided for exerting resilient forcesupon said members 46 and the plates 44 carried thereby for the perthe operations repeated with bottle to be labeled. 1

pose to be more fully set forth hereinafter. The brackets 25 are adapted. to rest upon the table or top I! and areprovided with slots M arranged to register with the transverse slots 20 of predetermined points thereon for co-operation with the aforesaid guide pins? in defining an enclosure for the supply stack of labels 23 In practice the guide members or pins 24* are adjusted lengthwise of the longitudinal slots 20' and the guide members or plates 44 along the transverse slots 20 and fixed in place, in the same way as described with respect to Figs. 1 and 2 to locate the supply stack of labels 23 at a pre determined point on the table IT. The form of apparatus illustrated in Figs. 5 and 6 is designed primarily for applying labels to articles of other than rectangular cross-section as for instance bottles A having cylindrical bodies, and necks provided with conventional annular beads a as shown by dotted lines in Figs. 5 and 6. In describing the operation of theapparatus it will be assumed that the labels 23 'are gummed although it is to be understood that the apparatus may be used equally well with ungummed labels, in whichcase the surface of the bottle A instead of being moistened to pick up the gummed label 23 will be coated with adhesive to cor- Y respondingly pick up an ungummed label.

To apply a gummed label 23 to a cylindrical bottle A, the latter, with its surface previously moistened, is placed between the parallel upright members 31 and the converging upright members 31 with the bead a in engagement with the bevelled edges 38 of the latter and with the body of said bottle A resting upon the guide pins 24 as shown by broken lines in Fig. 6 in the same way as in the form first described. A downward pressure is then manually exerted on the bottle A to depress the guide members or pins 24 and thereby bring the body of the bottle A into engagement with the outwardly flaring or curved ends 45 of the guide members or plates 44. If the. supply stack of labels 23 is sufficiently high as illustrated in Fig. 6, the bottle A at this stage will engage the terminal label 143 at the upper end of said stack, with said labelin tangential relation to the body of the bottle A. If previous removals of successive terminal labels 23 has reducedtheheight of the supply stack, or for some other reason the current terminal label 23 thereof is at a lo-werlevel so as not to be contacted by the bottle A when the latter initially engages the curved ends 45 of said plates 44, the

aforesaid downward pressure on said bottle A is continued. This will develop a camming action on said curved ends 45 whereby the plates 44 will be pivotally spread apart against the tension of the springs 48 to enable the bottle A to engage the terminal label 23 as indicated also by broken lines in- Fig. 6. In all other respects the apparatus shown in Figs. 5 and 6 may be constructed and operate in the same way as the one illustrated in Figs. 1 and 2.

In any" case, regardless 'of the height of the supply stack, the terminal label 23 at the top thereof will engage the bottle A in tangential relation thereto and will adhere thereto as the bottle A is removed from the apparatus. The application of the label 23 to said bottle A may then be completed. in any suitable manner and the next successive While the application of liquid to the bottles Aand A or equivalent articles, to moisten the surfaces thereof or to coat the same with adhesi-ve, may-be accomplished in any convenient manner, these operations may be advantageously carried out by means of devices such as illustrated in Figs. 8 and 9. The latter are shown in a form adapted to moisten the surfaces of the bottles A or A, or equivalent articles, and .Will

be so described; the devices may be used with equal efficiency for applying adhesive to said,

bottles or otherarticlesas will be apparent from thefdescription hereinafter.

In the illustratedform both devices include a base 49 and spaced upright supports 50 secured thereon in any convenient manner as by means of screws 5| or thelike, which pass through flanges 52 located at the lower ends of said supports 50. The latter, as shown, are further provided at their upper ends with outwardly projecting flanges 53 constituting rests for chan'- nelled members 54" and 54 respectively. The members 54 and 54? areprovided with flanges 55 which depend therefrom over the free'edges of the flanges 53 and serveto position the channelled members 54 and 54 between the supports 50 of the respective devices; in addition the members'54 and 54 respectively carry layers 56 and 56 of suitable materialsuch as felt or the like, which layers preferably extend over the tops of the'supports5ll and downwardly in surface engagement with the. depending flanges 55 as shown. In the preferred arrangement angle bars 5! are fitted over the'opposite edge portions of the layers 56 and 55 and's ecured in place by supplied thereto by capillary attraction through the medium of wicks 59 which are immersed in watercontained in receptacles 60 mounted on the bases 49 beneath the channelled members 1 and 54 The device shown in Fig. 8 is designed for cylindrical bottles and the like for which reason the channel member 54 isof curved forn'nand the layer 56, is correspondingly of curved form to provide a curved recess or trough;

- accordingly moistens the'surface' of said bottle A or its equivalent, to receive the label 23 as hereinbefore described; the device of Fig. 9 is similarly used for moistening the surfaces of articles of rectangular form such as the bottle A.

F Devices corresponding in construction shown in Figs. 8 and 9 but omitting the wicks 59 and. receptacles 6B and having-dry layers similar to.

thelayers 56 and 58 may be used to complete the application of j the labels to the bottles A and A or the like, subsequent to the initial application thereof by the apparatus previously described herein. In such case the operative steps may be carried out in the following-sequence: I

article such as forinstance the bottle A, is first placed in the trough-of the devicegof Fig. 8 in contact with the layer. 56-to receive moisture therefrom and is then placed in the apparatus of Figs. 5 and 6 and manipulated in the manner set forth hereinbefore to pickup a terminal label 23 from the supply stack. The bottle A5 with the picked up label is then placed in the trough of a device such as shown in Fig. 8 but with a dry layer 56 to thereby complete the application of the label 23 to said bottle A; it will be obvious as the bottle A with the initially applied label 23* thereon is placed in the trough of said device that the dry layer thereof will serve towipe said label 23 into firm and uniform adhesive contact with said bottle A.

The further form of the novel apparatus illustrated in Figs. 10 to 13 inclusive, corresponds in general construction and arrangement to those previously described, and differs therefrom only in details.

In the arrangement now being described, the carriers: 35 and upright members 37 with associated elements are replaced by another form of positioning means whereby the article to be labeled is located and guided in predetermined relation to the supply stack of labels 23. The stack of labels is maintained in place on the table or top H by means of depressible guide members or pins 24 corresponding to the guide members or pins 2 of Figs. 1 and 2, and mounted and operating in exactly the same way.

The article positioning and guiding means, in the specific form illustrated, is designed to support and accommodate bottles A of rectangular shape in cross-section, it being understood that this is illustrative only and not intended to define the limits of the particular positioning means. The latter consists of rods 6! slidably mounted in bosses 62 forming part of brackets 63 arranged in surface engagement with the lower face of the table ll in registry with the 1ongitudinal slots thereof. The brackets 63 are connected by means of bolts 66 and nuts 65 with co-operating plates or slides 66 resting upon the shoulders 22 of the slots 26 and slidably fitting the latter; washers 6? are located on the bolts 64 in engagement with the lower surfaces of said brackets 63 to provide bearing surfaces for the associated nuts 65. To increase the range of adjustability of the rods 6! lengthwise of the slots 20 through which said rods 6i extend in upright relation to the top or table H, the brackets: 63 may be provided with slots 68 for the accommodation of the bolts 64 as shown in Fig. 11.

At their upper ends the rods 6i are provided respectively with holders 68 and 69 which, in the illustrated example, are designed to receive and support rectangular bottles A it being understood that said holders 68 and 69 may be constructed also for accommodating bottles of different shapes and also other articles. 1

The holder 63 is in the form of a rectangular receptacle comprising an upright back and upright side walls HI and horizontal bottom lugs '01' members "H as shown in Fig. 12; in the preferred arrangementa fiat spring 12 is mounted uponthe inner face of one of the side walls 70 for maintaining the bottle A or equivalent articlefinnly in place in said holder 68. The holder 69 is in the form of an upwardly open or U-shaped receptacle consisting of a horizontal bottom member and spaced upright legs or members T3; in the preferred form a flat spring I4 is mounted upon the inside of one of the upright legs 13 as shown in Fig. 13.

Preferably the holders 68 and 69 are connected with the rods 6i so as to be readily disconnected therefrom at will, and for this purpose may be provided with internally threaded sleeves 15 for the threaded reception of the 'screwthreaded ends of said rods 6|; lock nuts 16 may be provided for locking the holders 68 and 69 in position on the rods 6| against unintentional movement thereon. The rods M with the holders 68 and 69 are maintained and returned to their normally raised positions by means of springs ll which have one end in engagement with the base I5 and their other ends in contact with pins 18 carried by said rods BI and serving in co-operation with the bosses 62 to also limit the upwardmovements of the rods 65 therein under the influence of the springs ll. As shown in Fig. 11, the rods 61 may extend downwardly through the slots 32 of the base [5 so as to have the required range of movement necessary to the operation of this form of the apparatus.

In practice, the supply stack of labels 23 is positioned upon the top or table ll by the guide members or pins 24 in the same way as in the form of the apparatus shown inFigs. l and 2. By properly adjusting the brackets 63 and fixing them in place by means of the bolts 64, nuts 65, and slides 66, the holders 68 and 69 are located so as to automatically present the bottle A or equivalent article in predetermined relation to said stack of labels 23.

Assuming that the labels 23 are gummed upon their upper surfaces and are stacked with their gummed surfaces upward, a bottle A is first moistened for instance by means of a device such as shown in Fig. 9, or in any other convenient manner, as by means of a suitable moistening pad. The moistened bottle A is then placed in position on the positioning means by having its bottom end set into the holder 68 in engagement with the upright back thereof and resting upon lugs ll. At the same time the neck of the bottle A is placed in the holder 69 in resting engagement with the horizontal bottom thereof and with'the conventional bead a of said bottle A in contact with the upright legs 13 of said holder 69 as shown in Figs. 10 and 11; it will be understood that the holders 68 and 69 are located by adjustment of the brackets 63 so as to automatically provide the above positioning of said bottle A without special efiort or care on the part of the operator. The springs 12 and M clamp the bottle A in place in the holders 68 and 69 against unintentional transverse movement relatively thereto while the back of the holder 68 in co-operation with the bottom of the bottle A and the upright members it ofthe holder 69 in co-op-eration with the bead a of said bottle A fix the latter against longitudinal movement in one direction; the springs 12 and M in addition to their other functions hold the bottle A against unintentional lengthwise movement in the opposite direction. When the bottle A is in place in the holders 68 and 69, said bottle A preferably engages and rests upon the guide pins 24 as in the form first described.

A downward pressure is now manually exerted on the bottle A which depresses the holders 6% and 69 against the tension of the springs H and at the same time correspondingly depresses the guide pins 24 against the. tension of the springs 33 to thereby bring the moistened surface of the bottle A into firm engagement with the gummed surface of the terminal label 23 currently at the top of the supply stack. .In this way said terminal label 23 is adhesively? at tached to the bottle A and adheres :thereto as the latter is removed from the apparatus. If necessary the application of said label 23 to said bottle A may be completed in any conventional:

manner; as by means of a device such as shown in of the operator; all that the latter is required to do is to place the previously moistened bottle A or its equivalent properly in place in the holders 68 and 69 and then to exert a downward pressure on said bottle A to bring the latter or any other article into engagementwith thecurrent terminal label 23 of the supply stack. after which the bottle A or equivalent article with the applied label 23 adhering thereto may beremoved from the apparatus.

The same procedure is followed if the labels 23 in the supply stack are not gummed with the exception that the bottle A or other article instead of being moistened is first provided with a coating of adhesive applied to that part of the surface of said bottle A 'or other article to which the label 23 is to be adhesively applied.

In all forms of the apparatus the stack of labels is located on a support at a predetermined point thereof, and the article to be labeled is positioned in predetermined relation to said stack and pressed into engagementlwith the terminal label thereof; the movements of the articles as pressure is applied thereto are controlled in predetermined relation to the supply stack so that the location of the labels on'the articles is predetermined and all labels of a given group are uniformly applied to successivear: ticles of a, given group. In all of its forms the apparatus is reliable in performing its functions and requires no particular skill in its operation.

Various changes in the specific forms shown and described may be made within the scope of the claims without departing from the spirit of the invention.
