LABEL-SUPPLY MECHANISM.

Specification of Letters Patent.

Patented April 6, 1909.

Application filed July 9, 1906. Serial No. 325,261.

T 0 all whom it may concern:

Be it known that I, FRANK O. WOODLAND, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Label- Supply Mechanism, of which the following is a specification, refer ence being made therein to the accompanying drawings.

This invention relates to improvements in mechanism for holding a supply pack, or packs, of labels in a labeling machine, and for taking labels sin 1y from the bottom of said pack or packs ofiabels to effect delivery and proper presentation of the same preparatory to their aflixment to bottles or other similar articles; and my invention consists in the novel features of construction, combinations, and mode of operation hereinafter more particularly specified and definitely pointed out in the claims.

The accompanying drawings illustrate this invention as arranged for dual labeling, or the simultaneous delivery of body-labels and neck-labels, and as adapted for use in a bottle-labeling machine of a class similar to that described in my prior application for Letters Patent, Serial No. 197 ,485.

Figure 1 represents a plan view of a label supply mechanism embodying my invention. Fig. 1 is a plan view of one of the followerplat'es. Fig. 2 represents a side elevation view partly in section, and Fig. 2 a side View of the picker devices, in their corresponding relation, as employed in cooperation with the parts shown in Fig. 2. Fig. 3 represents a plan view of one of the glue-applying pickers; Fig. 4 a transverse section of the same shows, by side, front and plan views, a detail of one of the guide-stakes having knife-edge face and peel-off ends. Fig. 9 1s a sec tion of the same at line at m. Fig. 10

shows, by side, front, and section plan, a detail'of one of the sustaining guide-stakes; and Fig. 11 is a separate plan and side view of the follower-cramping piece.

Referring to the drawings, A denotes an upper portion of the labeling machine frame;

B the label-holder frame, which is removably supported upon the machine frame by sockets that fit over upright studs a or in other suitable manner. The label-holder frame, as shown in the present instance, is composed of a rear member or attachingpiece 12 and a front plate 10 connected by horizontal side rods 11; and mounted to slide on said rods, or one'of them, there is a back-plate 14 and intermediate plates or bars 12 and 13, to which the stakes or arts that guide and support the label-packs are secured preferably by screws 8, or other suitable fastenings. The back-plate is provided with bearings 4 in which the right and left threaded adjusting-screw shaft 15 is mounted; and supported in connection with said shaft are right and left adjustable cheekplates 16 that carry the guide-stakes 6 for the ends of the body-label pack.

The compartment or pack for supplying body-labels is indicated by letter L, and that for supplying neck-labels by letter L Upon the front plate 10 there are laterally adjusting brackets 17 that carry the stakes 7 for the ends of the neck-label compartment L Said brackets, as shown, are secured by clamp-screws 1S thatv pass through slots in the plate. The backplate 14 and intermediate plates 12 and 13 are adjustable forward and rearward onthe side rods 11, and are held at adjusted position by set-screws t, 25 or other efficient fastening means.

'i he size and relative position of the labelholding compartments may be varied by adjustment of the stake-supporting members or plates 12, 13, 14 and 16, aswill beunderstood. The peculiar construction, arrangement and mode of operation of the label-supporting and guiding means is hereinafter more fully explained.

Extending over the compartments of the label-holder I arrange a follower carrierbar F, approximately rigid against upward or downward movement, and adjustably mounted thereon is a head or guide-device G at each of the compartments L and L A vertically sliding follower-rod 2-0 is arranged through said guide and adapted for resting its lower end upon the label pack, or upon the follower-plate 21 covering the pack of labels. The follower rods and their guidedevices being of similar construction, a description of one set will apply to either or both, and the parts are therefore similarly indicated on each set.

The guide-piece G has a horizontal mortise to fit over the carrier bar F, and a set-screw 19 for retaining it at position thereon. Said guide-piece is formed with a horizontal laterally projecting lower member or aw 22, and an u per jaw or member 23 having a downwar ly overhanging end; each member being provided with a hole for guiding the rod therein. In the space between the guide members I provide a loose plate 25 having near one edge a hole 24 through which the rod. passes in alinement with the guiding roles in the members and 23. The plate 25 extends beyond the end of the member 22 sufli ciently to give a preponderance that will cause friction of the plate against the rod, so that an upward pressure or movement of the rod will cause the plate to cramp or grip upon the rod and thereby resist any lifting action on the follower-plate or pack of labels. 'lhe outer end of the cramp plate contacts with the overhanging end of the upper guide members and insures a firm grip on the rod when lifted, but the follower rod can descend "reely, since the cramping action is then. prevented by the plate being sustained by the lower guide member 22. Small pins 26 can be employed to keep the plate 25 from swinging out of place laterally.

'lhe follower rod F may be solid or tubular, andv of round or other cross-sectional shape. It is best made with a slight flange or bur at its lower end and a knob at its upper end, so it cannot pass through and escape from the opening in the guiding head G. Preferably the foot of the follower rod is slitted and the two halves slightly spread apart, as shown at d on. Fig. 2; thus affording outwardly springing members that will cause the lower part of the rod to bind or give sufiicient friction in the guide-head to retain the rod self-sustained in elevated position, when it is drawn up to its full extent, to give access to the label compartments; or when it is desired to swing the follower devices to one side.

'lhe follower-plate 21 is best made of a size somewhat greater than the labels and somewhat crowned. or curved upward at the center, (see Figs. 2 and 6) so that it bears upon the labels chiefly along the edges of the pack. The edges of the plate may be notched, as shown in Fig. 1, to accommodate the label-holder stakes, and so that the edges of the plate can project over the edges of the labels. This permits of the plate being of light weight and greater efficiency.

The bar F is preferably attached to the frame A by a hinging joint 27, so that the follower devices can be swung laterally to one side when it is desired to charge the compartments with labels; or to remove the label-holder from the machine. The hinging-piece F is best provided with a spring pressed stud 28 and spring 29 (see Figs. 1 and 7 for retaining the parts at adjusted positions by the point of the stud entering a properly disposed recess in the frame casting. A stop-lug (1 may be formed on the frame for arresting the forward swing of the bar F at its working position.

The glue-applying pickers 30 are detachably secured to vertically reciprocating arms, or carriers 1, and. move to and from the bottom of the label-holder, as indicated by the arrow on Figs. 2- and 2. As a feature of improvement the picker-plates are each formed with a flat glue-carrying face 32 and a border face 33 slightly downwardly inclined and meeting the glue-carrying face at an obtuse angle 34. 'l he outer end of the picker face is also made with a downward incline, as at 35. The inner edge of the picker may be slightly rounded or beveled, as at 36, along the face portion.

lhe glue-carrying face 32 bridges the space between the label-pack compartments or extends uninterruptedly from end to end of the picker face; thus affording a continuous level track for the glue-delivering roller R. W hen in operation the glue-delivering roller It meets the picker upon the end incline and rolls along the face 32 toward the opposite end.

The effect of the inclined border surface 33 is that as the roller travels along the picker face the receding roll surface tends to drag the glue laterally at the angle 34 from the inclined portion 33 to the flat portion 32, and to thereby avoid an excessive accumulation of glue along the edge of the pickers, by the repeated actions, as occurs when the glue-applying faces terminate with an. aln'upt offset or square edge. Likewise the incline tends to prevent accumulation of glue on the end of the picker. This feature of im provement in the formation of picker faces is of considerable prac 'cal utility in the operation of label supply mechanism, in labeling machines of the class specified.

The picker-carrying arms I are, in practice, attached to a reciprmating slide (not shown) that moves up and down on a suitable guide, and is cmnbined with means for imparting motion thereto in the desired order of action with respect to other parts of a labeling machine. The pickers are caused to approach the bottom of the label holder, as in F 6, their faces 32 having been glue-coated by the roller R as they moved upward. After taking a label from the bottom of the packs they move down ward to the position where the label is preseated for alfixment to the bottle, as heretol'ore practiced.

A feature of my invention consists in providing a label-sup ply mechanism with means for guiding and sustaining a pack, or packs, of labels, and having facilities for partially peeling or rolling up the edge of the pasted or glued label from the picker-face as it is LOO taking the label from the bottom of the pack. As a practical embodiment of this feature I provide at the front and rear of the label compartments dual sets or uprights or stakes 3 and 5, comprising what for convenience may is termed sustaining stakes 3, and edge-guiding stakes 5. The latter are formed with narrow lower ends and inwardly projecting inclined portion 51 that extend beneath the pack of labels L. For som distance above the inward incline the stake is reduced and beveled, as at 52, Fig. 9, so to present an approximately knife-edged or very thin contact face 55' for guidingcontact with the edges of the labels. he sustaining stakes are formed with the body portion of less dimension, so they do not touch the edge of the labels, but are provided each wth an inwardly projecting lug 31 at the lower end, properly rounded on its extremity, and upon which the pack of labels is upheld. The inward ln s 31. of the stakes 3 are best arranged at a higher level than the inwardly projecting pickers are forced against the bottom of the pack of labels.

In the operation of the means constructed and arranged as above described, the ends oi the guide-stakes act to peel oil' and bend up the corners of the label from the face of the picker, without releasing it wholly therefrom, while the label is being drawn from the inwardly projecting. ends or sustaining lugs 31, thereby giving a peculiar crimp to the labels that eiiectually prevents the taking of more than a single label from a pack at one time. The lugs 31 are out of reach of the glue, but the peeling hooks or ends 5], being necessarily within the gluecoated area will take on some glue; but the knife-edged guiding faces 55 obviate liability of getting glue on the edges of the labels in the pack sufficiently to stick ticni together. For narrow neck-labels the end guide stakes 7 canbe made straight as at E, or without the inward projection, since the two side guides are so near together that they will accomplisn the peel-oil action.

The rear edge of the several niiortises 56 and are best formed with an upward member 51 ot the stakes 5, as shown in Figs. and 7 The inclination, asindicated on Fig. 55, and shown at r on Fig. 5, so that as the roll it passes over them the receding action of the roll suri'ace tends to draw up the glue to itself and to thus obviate any accumulation of glue within the niortisos.
