10 Claims.

The invention relates to machines for adhesively applying labels and other elements to articles, and has for its object to provide machines of the indicated class with simple and efiicient means whereby parts of the mechanism may be readily adjusted to the most efficient operative condition and to compensate for wear and the like. The invention contemplates further the provision of means whereby the suction head or equivalent transfer device common to machines of the designated types may be accurately maintained in the most effective operating adjustment. A further object is to provide simple and efficient means whereby the application of adhesive to labels and other elements may be controlled in a predetermined manner. Other more specific objects will appear 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 fragmentary side elevation, partly in section, of an applying machine with the novel features embodied therein; Fig. 2 is a fragmentary side elevation on a somewhat enlarged scale and looking in the opposite direction from Fig. 1; Fig. 3 is a plan view of the parts shown in Fig. 2; Fig. 4 is a vertical section on the line 4--@ of Fig. 2; Fig. 5 is a horizontal section on the line 5-5 of- Fig. 4; Fig. 6 is a detail section of a guide rail included in the machine; Fig. 7 is a fragmentary section on the line Il of Fig. 4; 8 is a section elevation on the line 8-4 of 1; Fig. 9 is a detail I plan view of a novel arrangement for controlling the application of adhesive to elements to be adhesively applied to articles; Fig. 10 is a fragmentary section on the line iii-it of Fig. 9; Fig. 11 is a similar view on the line li-Il of Fig. 9; Fig. 12 is a rear face view of an article subsequent to the application of adhesive thereto, and Fig. 13 is a rear face view of a label or other element illustrating an example of adhesive application thereto.

The machine selected for the purpose of illustrating the novel features includes a suitable frame i5 on which a container or hopper it of any conventional type is supported in any convenient manner for the purpose of containing a supply of labels or other elements I! in the form of any upright supply stack. Generally speaking, the bottom of the container I6 is vertically adjustable by means of suitable elevating mechanism automatically controlled in a manner to periodically restore the upper end of the stack of labels or other elements I! to a predetermined level. For this purpose the machine may include a feeler l3 vertically slidable in an upright guide l9 and connected by means of a link 20 with a bell-crank lever 2i pivoted at 22 upon the frame [5. The lever 2| carries a roller 23 adapted to be acted on by a cam 24 to vertically actuate the feeler IS in operative synchronism with the means whereby the labels or other elements [1 are successively removed from the stack in the container Hi; the cam 24 is carried by a shaft 25 suitably journalled in the machine.

In addition the illustrated machine includes adhesive applying means consisting of a distributing roll 26 rotatably mounted in the frame [5 and dipping into a supply of adhesive in the well-known way; the distributing roll 26 is located in tangential relation to an adhesive ap plying roll 27 suitably journalled in the machine in operative relation to the container and stack of labels or other elements I! as shown in Fig. 1.

The means whereby individual labels or other elements I! are successively removed from the upper end of the supply stack and transferred therefrom for adhesive application to the articles for which the labels or other elements are designed may be of the suction operated or any other suitable type. The said transfer means, in its illustrated form, consists of a carriage 2B slidably mounted upon a fixed guide rail 29 suitably supported on the frame I5 as shown in Fig. 1. Suitable means of conventional type is provided for slidably reciprocating the carriage 28 on the rail 29 and, as shown, comprises an arm 30 fixed on the shaft 25 and having its free end pivotally connected with a coupling rod 3| which in turn is yieldingly and pivotally connected at 32 with the carriage 28. It will be understood that the shaft 25 is rocked on its axis in properly timed relation with the other elements of the machine in any convenient and well-known manner.

In the operation of the machine, the carriage 28 with its associated elements, to be more fully set forth hereinafter, is reciprocated on the rail 29 many times during an operative period and at opposite ends of its reciprocating movements engages adjustable abutments 33 suitably mounted on the frame I5. Obviously repeated reciprocation of said carriage 28 lengthwise of the rail 29 results in wear of the parts; the latter finally disturbs the co-operative association of the parts and develops conditions whereby the efficiency and operative accuracy of the machine is reduced.

To overcome these disadvantages without requiring replacement of parts with consequent expense and loss of time, the machine is provided with novel means whereby the aforesaid wear may be compensated and the effects thereof neutralized in a simple and efficient manner. As illustrated in Fig. 4, the rail 29 is accordingly provided along its opposite longitudinal edges with guide-members 34 formed with V-shaped or equivalent guide grooves 35 into the upper of which is slidably fitted an upper slide member 39. The latter is mounted in fixed position upon the carriage 2 3 in any suitable manner and, as shown, is provided at its opposite ends with lugs 31 for the accommodation of screws or the like 38, whereby said upper slide member 35 is fastened in place on convenient parts of said carriage 28. A similar lower slide member 39 is slidably fitted into the lower guide groove 35 of the rail 29 and is adjustably mounted on the carriage 28 in any convenient manner; for instance, as shown in Fig. 2, the lower slide member 39 may include lugs 40 located at its opposite ends and provided with slots 41 for the accommodation of screws 42 which are threaded into contiguous parts of the carriage 28. The latter further carries set screws 43 which bear against the lower slide member 39 and are fixed against unintentional movement by means of lock nuts 44. It will be understood, as shown by way of example in the drawings, that the

slide members

33 and 39, in every instance, are shaped in cross-section to properly and slidably fit the guide grooves 35.

With this arrangement the lower slide member 39 may be adjusted relatively to its associated guide groove 35 to a set position on the carriage 28 for proper cooperation with the upper slide member 38 to slidably mount said carriage 23 most efiiciently on the rail 29. play resulting from wear disturb the efiiciency of the mounting of the carriage 28 on the rail 29, this may readily be corrected by properly adjusting the lower slide member 39 relatively to the associated guide groove 35 to a new set position on said carriage 28. The aforesaid adjustment of the lower slide member 39 may be easily and accurately effected by loosening the screws 42 and the lock nuts 44 and then manipulating the set screws 43. The latter by bearing against the slide member 39 will cause the latter to move relatively to the screws 42 into the lower groove 35 of the rail 29, such movement being possible because of the slots 4|; when the desired adjustment has been accomplished, the screws 42 are tightened to secure the member 39 in its new set position and the lock nuts 44 are screwed up to prevent unintentional dislocation of the set screws 43.

In addition to the parts so far described, the machine includes means on the carriage 28 and operated at the opposite ends of the reciprocatory movements thereof to respectively pick up successive labels or other elements I! from the supply stack and to apply them to the articles for which said labels or other elements I! are designed. As shown in the drawings, the aforesaid means consists of a carrier or member 45 slidably mounted on the carriage 28 for vertical reciprocation thereon and provided at its lower end with a yoke 43 as shown in Fig. 8. A suction head 4'! is mounted upon the yoke 45 in any convenient manner and is connected with a suitable source of suction, for instance, by means of a flexible tube 48; as the suction head and suction producing means may be of any conventional If looseness and type and per se form no part of the instant invention, it has been deemed unnecessary to illustrate the same in detail.

As the vertical reciprocation of the carrier 45 and its associated elements relatively to the carriage 28 results in wear of the parts over a period of use which may result in disturbing the accuracy of operation of the machine, novel means is provided for compensating such wear in a simple and efficient manner and without requiring repeated replacement of parts. As shown in Figs. 3 and 5, the carrier or member 45 is accordingly provided along its opposite vertical edges with guide grooves 49 of V-shape or equivalent form in cross-section, into one of which is slidably fitted a slide member 59. The latter is mounted in relatively fixed position on the carriage 28 in any suitable manner, as as shown, is provided at its opposite ends with lugs 5| for the accommodation of screws 52 whereby said slide member 59 is fastened in place on convenient parts of said carriage 28. A similar slide member 53 is slidably fitted into the opposite guide groove 49 of the carrier or member 45 and is adjustably mounted on the carriage 28 in any convenient manner; for instance, as shown in Fig. 2, the slide member 53 may include lugs 54 located at its opposite ends and provided with slots 55 for the accommodation of screws 56 threaded into contiguous portions of the carriage 28. The latter further is provided with lugs 51 having threaded apertures for the screwthreaded reception of set screws 58 which bear against the outer edge of the slide member 53 and are fixed against unintentional movement by means of lock nuts 59. It will be understood, as shown by way of example in Figs. 3 and 5, that the

slide members

59 and 53 are shaped in cross-section to properly and slidably fit the guide grooves 49.

With the aforesaid arrangement the slide member 53 may be adjusted relatively to the associated guide groove 49 to a set position on the carriage 28 for proper co-operation with the slide member 50 to slidably guide and accurately maintain the carrier or member 48 in its intended path of reciprocation without objectionable vibration. If looseness and play resulting from wear develop after a period of use to disturb the efficiency of the slidable mounting of the carrier or member 48 on the

slide members

59 and 53, this may be readily corrected by properly adjusting the slide member 53 to a new set position on said carriage 28. The aforesaid adjustment of the slide member 53 may be easily and accurately eflected by loosening the screws 56 and lock nuts 59 and then manipulating the set screws 58. The latter by bearing against the outer edge of the slide member 53 will shift the latter relatively to the screws 55 into the associated guide groove 49 of the carrier or member 45, such shifting being possible because of the slots 55; when the desired adjustment has been accomplished, the screws 56 are tightened to secure the slide member 53 in its new set position and the lock nuts 59 are screwed up to prevent unintentional displacement of the set screws 58.

The operations of resetting the slide member 39 to neutralize disturbances in the slidable mounting of the carriage 28 on the rail 29, and the slide member 53 to compensate disturbances in the slidable mounting of the carrier or member 45 on the carriage 28, may be repeated as often as required. In this way the carriage 28 and the carrier or member 45 may be accurately maintained in their respective paths of reciprocation, and objectionable looseness and vibration in the respective parts maybe definitely avoided without requiring frequent replacement of said parts.

As shown in the drawings, the machine includes means for maintaining the carrier 45 against downward movement on the carriage 28 throughout predetermined portions of its reciprocative movements to thereby position the suction head 41 and a label or other element ll car ried thereby, in proper relation to the adhesive applying roll 21 to receive an application of ad-' hesive therefrom as will appear more fully hereinafter; provision is also made for effecting vertical reciprocation of the carrier 65 relatively to the carriage 28 at the proper points in an operative cycle of the machine to effect the desired operative steps.

The illustrated machine accordingly is provided with a stationary supporting rail 60 mounted in place in any suitable manner for instance in parallel relation to and at a predetermined distance above the rail 29 as shown in Figs. 1 and 4. The rail 68 is formed in its upper edge with recesses (H and 62 located in predetermined relation respectively to the stack of labels or other elements H in the container l6 and to the applying station at which the labels or other elements [7 are applied to articles A for which they are designed; the articles A referred to are supported in position for adhesively receiving the labels or other elements I! in any convenient manner at said applying station. A movable supporting rail 63 is located in spaced parallelism with the stationary supporting rail so, and as shown in Figs. 4 and 8 may be provided with a flange 64 along its free edge, the upper surface of said flange 64 being in the same horizontal plane with the upper surface of the rail 69. In the illustrated arrangement the

rails

69 and 63 are located upon opposite sides of the path of reciprocation of the upper portion of the carrier 45, it being understood that the movable rail 63 is of sufiicient length to extend throughout the horizontal path of movement of the suction head 41 and associated elements in the performance of their operative functions. The movable supporting rail 63 is carried by one or more arms 65 fixed upon a shaft 66 suitably mounted in the machine for instance as shown in Fig. 8, said shaft 66 having a lever 67 fastened thereon and operatively connected in any convenient manner with conventional mechanism operating in properly timed relation with the other elements of the machine to rock said shaft 66 and thereby raise and lower said rail 63 to correspondingly operate the carrier 3'? and suction head d? on the carriage 23. For co-operation with the

rails

59 and 63, the carrier 45 is provided with

rollers

68 and 68 rotatably carried by a stud to project ing through a bearing lug H projecting upwardly from the upper end of the carrier 25 as illustrated in Figs. 2, 4, and 8; the stud may be in the nature of a bolt provided with a head w and a nut 18 The arrangement is such that the roller 68 travels in rolling engagement with the upper or traction surface of the stationary supporting rail 60 while at the same time the roller 69 travels in rolling engagement with the upper or traction surface of the flange M of the movable supporting rail 53. A spring 45 may be provided for developing an elastic tension on the carrier 45 to thereby yieldingly maintain the

rollers

68 and 69 in rolling engagement with the

respective rails

60 and 63.

To neutralize the effects of wear and to enable the active surface of the suction head 41 to be maintained at and adjusted to the most efficient level relatively to the adhesive applying roll2l, the stud 10 passes through a sleeve or bushing 12 in eccentric relation thereto. The bushing 12 is fixed upon the stud 10 in any convenient manner and is rotatably mounted in the bearing lug H as shown in Figs. 4 and 5, a set screw 13 serving to fix said bushing 12 in its adjusted position. Obviously if the bushing 12 is rotated in the lug II, the stud 10 will be adjusted to different positions relatively to the supporting

rails

60 and 63 and will adjust the

rollers

68 and 69 correspondingly to compensate for wear of the parts or for purposes of adjusting the level of the active face of the suction head 41. The aforesaid adjustment also enables the latter to be set so that the labels or other elements carried by the suction head 41 regardless of the thickness of the material, will always be positioned for proper tangential engagement with the adhesive roller 21 to receive an application of adhesive therefrom. The rotatable adjustment of the bushing 12 may be effected in any suitable manner as for instance by loosening the nut Ill and then rotating the stud ll] on its axis by means of the head Hi this manipulation of the stud 10 is communicated to the bushing 12 as will be apparent.

The machine may also be provided with means for controlling the application of adhesive to the labels or other elements I! in a predetermined manner, as exemplified by restricting the application of adhesive to only certain parts of said labels or other elements H and preventing adhesive from being applied to other parts of said labels or other elements IT. For instance, in many types of label application it is desirable to apply strips of adhesive a along opposite edges of a surface of a label I! and to leave the intermediate portions b of said label I! free from and uncoated with such adhesive as shown in Fig. 13; in other cases, the labels may be coated with adhesive by beginning the application thereof at an intermediate point of the surface of a label ll or its equivalent, and continuing said application to an edge thereof as illustrated by the right hand strip a in Fig. 13. To obtain this result, a cam member 14 is mounted on the fixed supporting rail 60 in predetermined relation to the adhesive applying roll 21. In the preferred arrangement the cam member 14 is adjustably mounted on the rail 69 and for this purpose may be formed with a slot 15 for the accommodation of a set screw 16 threaded into an aperture II with which the rail 60 is provided. To enable the cam member 14 to be mounted at different points along the rail Gil, the latter may include a plurality of apertures ll each arranged to receive the screw 16 or its equivalent. With this arrangement it is also possible to con-currently mount a number of cam members M at different points of the rail Ell to obtain various types of adhesive application to a label or other element H.

In practice, assuming the machine is used for adhesively applying successive labels 57 to suecessive articles A suitably supported at the applying station of the machine, and that in Fig. l the parts are shown in position at the socalled label applying station of the machine subsequent to the application of a label I? to an article A, the shaft 66 will be rocked in properly timed relation with the other elements of the machine, by the lever 61 and its operating mechanism in a direction to swing the arm or arms 65 and with them the movable supporting rail 63 in an upward direction. A lifting action will thus be exerted on the roller 69 to thereby raise the carrier 45 and with it the suction head 41 on the carriage 28 to a position above that shown in Fig. 1 so that the active face of the suction head 47 is at a level higher than that of the adhesive applying roll 21.

As the shaft is now rocked on its axis, the lever will be swung to the right in Fig. l and by means of the coupling rod 3| will slidably pull the carriage 28 in the same direction lengthwise of the rail 29 until said carriage 28 engages the right hand abutment 33, at which time the suction head 41 will be located above and in registry with the upper end of the stack of labels I! in the container l6. During these operative steps,

the cam 24 partakes of the rocking movement of the shaft 25 and by acting on the roller 23 will swing the bell crank lever 2| in a direction to raise the feeler I8 away from the upper end of the supply stack of labels I! to an inoperative position in which it does not interfere with the subsequent actuation of the suction head 41 in the removal of a terminal label I! from said supply stack.

As the carriage 28 is thus slidably moved to the right on the guide rail 29, the roller 69 will travel lengthwise of the elevated supporting rail 53 to thereby maintain the carrier in a raised position on said carriage 28, in which raised position the active face of the suction head 41 a is at a higher level than the adhesive applying roller 2? and accordingly does not contact therewith. At the end of this sliding movement toward the right, the roller 68 will be above and in registry with the recess 6| of the stationary supporting rail 60, with the roller 69 still in rolling engagement with the elevated supporting rail 63. At the proper moment the shaft 65 will be rocked in a direction to swing the arm or arms 65 downwardly to thereby lower the supporting rail 63 and with it the carrier 45 on the carriage 28. The roller 68 thereby moves downwardly into the recess 6| of the rail 60 and the suction head 41 moves into engagement with the upper end of the supply stack of labels I1.

In proper operative synchronism with these operations suction will be automatically developed in the suction head 41 in any conventional manner and will cause the terminal label I! in the supply stack to adhere to the active face of said suction head 41 in the Well-known way.

When the terminal label I! has thus been picked up, the shaft 66 and arm 65 will be rocked in a direction to elevate the supporting rail 63 and roller 69 to thereby raise the carrier 45 and. suction head 41 with the picked up label I! and to concurrently lift the roller out of the recess 6| to the level of the traction surface of the stationary supporting rail 60. At this stage, the mechanism will be operated to slidably shift the carriage 28 along the guide rail 29 toward the left in Fig. l, the roller 68 meanwhile traversing the fixed supporting rail to thereby maintain the carrier 45 and its associated parts in the aforesaid raised position as the carriage 28 travels along the guide rail 29; it will be understood that the supporting rail 63 is moved downwardly and away from the roller 59 at the beginning of the aforesaid operations in the wellknown way.

In this position of the parts, the lower surface of the label I! carried by the suction head 41 is at the level of the adhesive applying roll 21 and will be caused to pass over and in tangential surface contact therewith as the carriage 28 travels to the left, whereby said lower surface of said label I! will receive a coating of adhesive from said roll 21. If a cam member 14 is in place on the supporting rail 60, for instance, as illustrated in Fig, l, the roller 68 will pass over said cam member 14 and accordingly will lift and lower the suction head 41 and the label I! carried thereby, whereby the intermediate portion b thereof will be prevented from contacting with adhesive applying roll 21, and strips of adhesive a will be applied only to the opposite edge portions of said label IT as shown in Fig. 13; in other cases, an adhesive receiving relation will be established with the applying roll 21 beginning at a predetermined intermediate point of the surface of the label [1 or its equivalent, and continued to the rear edge thereof as illustrated by the right hand strip a in Fig. 13. In such case the application of adhesive to the label I! or equivalent element begins after the leading edge of said label I! or equivalent element has passed beyond the axis of the adhesive applying roll 21 in the direction in which said label I! or equivalent element is being carriedby the suction head 4? or equivalent transfer means.

As its travel to the left in Fig. 1 continues, the carriage 23 will finally engage the left hand abutment 33 and come to rest. At this stage, the roller 68 is located above and in registry with the recess 62 of the stationary supporting rail and the suction head 4! with the label H carried thereby is in label applying relation to the particular article A located in the machine at the time. In proper operative synchonism with the other parts of the machine, the shaft 65 is rocked in a direction to swing the arm 65 and supporting rail 63 downwardly and slidably lower the carrier 45 on the carriage 28 to thereby cause the suction head 4! to bring the label I! carried thereby into contact with the article A, it being understood when this initial application has been completed that the suction in the suction head 41 is automatically cut off. As a new operative cycle is now started, the suction head 4'! is raised and the particular label I! remains in adhesive connection with the article A. The adhesive application of said label I! to said article A may be completed by means of a conventional pressure member 18 operated in any well-known manner in proper timing with the associated mechanism. When the application of the label has been completed, the labeled article A is removed from the machine and replaced with another article A after which the aforesaid operations are repeated.

During an operative period, the

slide members

36 and 39 in co-operation with the guide grooves 35 maintain the carriage 28 in its intended path of reciprocation without harmful vibration, and the

slide members

50 and 53 in co-operation with the guide grooves 49 correspondingly maintain the carrier 45 in its vertical reciprocative path on the carriage 28 in an efficient and reliable manner. As previously explained herein, disturbances of these conditions resulting for instance from wear of the parts, may be corrected b periodical adjustment of the

slide members

39 and 53 respectively.

In Figs. 9, 10, and 11, I have shown another form of the means for controlling the application of adhesive to the labels or other articles in a manner to apply the adhesive only to certain parts of the labels or other articles, and to avoid such application to other parts thereof. To exemplify this last-named controlling means and its operation, I have illustrated it in a form adapted for applying adhesive to an element or blank ll intended to be adhesively attached to an article such as a paper drinking cup and ineluding handle sections 1) foldably connected along score lines 11 with a body section a which, as shown, may be provided with transverse ears or projections a extending in opposite directions from said body section a at opposite ends there of. In its normal condition, the element or blank I! is fiat and in this condition is adhesively applied to a paper drinking cup or equivalent article in a manner to leave the handle sections b free to be bent toward each other on the score lines I) so as to project outwardly fro-m said cup or other article to constitute a handle therefor. In practice, a supply of elements or blanks I! in fiat condition may be located in the form of a supply stack in a container such as the container l6 of Fig. 1. During an operative cycle of the machine, which may be constructed and operated in the same way as the machine shown in Fig. 1, individual blanks Il are removed from the upper end of the supply stack and transferred to the applying station of the machine for adhesive application to the cups or other articles for which said blanks are designed. During their travel from the supply stack to the applying station, the blanks l'l receive an application of adhesive (1 controlled in such a way that only a surface of the body a and projection a receive the adhesive coating while the corresponding surfaces of the handle sections 1) receive no adhesive as shown in Fig. 12; the application of adhesive a may be effected by means of an adhesive applying roll 21 corresponding to the roll 21 of Fig. 1.

The aforesaid controlling means, as shown in Figs. 9, 10, and 11, may comprise cam members I l each having one end curved or otherwise projected downwardly as illustrated at la The cam members M may be fixed in place in the machine in any suitable Way and, as shown, are provided with upright longitudinal flanges 19 attached to brackets or arms 89 which themselves are mounted in the frame I5 in any convenient manner. In any case, the cam members I i are located in parallel relation to each other at a predetermined distance apart in co-operativerelation to the adhesive applying roll 2'1 and extending beyond the same as illustrated by way of example in Figs. 9, 1i), and 11. The suction head H corresponding to the suction head ll of Figs. 1 and 8 is dimensioned and shaped in dependence upon the character of the blank or element ll and is mounted in the machine and operated therein in the same way as in Fig. 1; thus in the instant case the suction head W corresponds in width to the width of the body section a of the blank or other article ll and is of a length substantially corresponding to the length of said body section a as shown by broken lines in Fig. 11.

With the described arrangement when a blank I! has been picked up from the supply stack by the suction head 41*, the body section a will be drawn and held against the active surface thereof by the suction in said suction head M while the handle sectionsb' of said blank ll will project laterally beyond the suction head 41* in opposite directions; if necessary or desired, provision may be made on the suction head 4'! to provide backings for the projections a of said blank ll to maintain the same in position during the application of adhesive thereto. In any case, as the suction head 41* carrying a blank ll approaches the adhesive applying roll 21 the handle sections 1) will ride up on the curved or equivalent ends 14* and along the cam members 14 and will thereby be swung upwardly on the score lines b as illustrated in Figs. 10 and .11. In this position the handle sections b are maintained out of contact with the adhesive applying roll 2'! and are retained in this position until said sections b pass from the cam members I i at points beyond the adhesive applying roll 2?. Meanwhile, the common bottom surfaces of the body section a and projections a have passed in progressive tangential engagement with said applying roll 21 and have received a coating 0, of adhesive therefrom as shown in Fig. 12. As the operation of the machine continues, the blank ll will be deposited upon the cup or other article at the applying station to adhesively connect the body section a and projections a therewith and leave the handle sections b" free to be bent outwardly at will on the score lines b to provide a handle for said cup or other article. Obviously the blank ll or its equivalent may be designed for adhesive connection with other articles to serve otherwise than as a handle therefor, in which case the controlling means will be arranged to effect a properly co-operating application of adhesive. 7 l?he means for controlling the application of adhesive in the form of strips to a label or other element avoids the necessity for expensive strip gumming rolls or other correspondingly expensive special devices. The described controlling means is particularly desirable for applying strips of adhesive or other patterns thereof on 1abels or other elements which are made of heavy materials or of such thickness as to be incapable of being temporarily distorted out of their normal surface planes as is done in certain types of pattern gluing. The controlling means further provides a simple and eificient arrangement for bringing about the application of adhesive only to certain parts of a label or other element and leaving other parts thereof free of adhesive for any predetermined purpose. The controlling means in all of its forms may readily be incorporated in existing machines.

The novel means for compensating wear of parts require no skill in their manipulation and are of maximum efficiency in action and definitely insure accurate application of labels to the articles at all times without necessitating frequent replacement of parts.

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.
