Figure l represents a diagrammatic view showing how a label-pressing roll, which is centered on the upper connecting link, will describe a path of travel generally parallel to the base of the labeling machine; the initial and final positions of the links of the labeling machine being shown in dashed-dotted lines, the intermediate position of these links being shown in full lines, and thev path of travel described by the upper ends of these links being shown in dashed lines.

In the machine of the present invention, a table or platen I5 is preferably adjustably carried upon a base I6 by means of the similar pairs of cross links I1 and I8, the lower ends of which are pivotally secured at I9 and 29, respectively, on slidable blocks 2| and 22, respectively, which are guided within the base for rectilinear motion in linev with eachother. The blocks 2l and 22 are provided with aligned openings which are internally threaded in opposite directions (one a left-hand thread'and one a right-hand thread) and through which an adjustment bar 23 is extended having similar oppositely threaded end portions adapted threadedly to engage the blocks. The adjustment bar 23 may be held against axial displacement by the collars 24 and 25 affixed thereto and bearing against the end walls 26 and 21, respectively, of the lower frame structure.

A wing nut or knurled nut or any other suitable handle member 28 is provided at the front end of the bar 23 whereby the same may be turned for raising or lowering thertable platform I5.

The links are pivoted to each other at 29.

By suitable rotation of the wing nut 28, the lower ends of the crossed links I1 and I8 are caused to either approach or withdraw from each other, causing their respective upper ends 36 and 3l to slide in grooves 32 and 33, respectively, on the underside of the platen I5. On each side of the base I6, vertical platen guides 34 and 35 are anchored by means of suitable screws 3,5. CorrespondingV slots in the platen l5 register with these vertical guide members and vertically control the motion of the adjustable platen. A pair of coiled springs 31 and 38 are attached to the underside of the platen I5 at opposite ends thereof and are joined together under a pin 39, said pin extending between, and being secured to, the spaced pairs of crossed links l1 and I8 at their fulcrum points 29. These coiled springs 31 and 38 draw the platen I5 down against the upper end of links I1 and I8. At one end of the platen l5 a vertical stop 49 is secured for limiting the position of the bottle being inserted on the platen.V A flat and comparatively thick layer -of sponge rubber 42 covers the upper surface of the platen i5. Notches 43 and 44 are centrally located on opposite edges of this rubber surface in order that it may clear the vertical platen guiding members 34 and 35.

Adjacent the opposite end of the platen I5, a vertically slotted bottle-neck-receiving guide member 4I is secured to the bed plate I5 and aids in guiding the bottle I4 into position on the platen surface 42. The presence of this guide member 4l, however, is not essential and this member may be entirely dispensed with, in which case the bottle about to be labeled would be positioned primarily by means of the guide- rails 45 and 46. Y

The pair of bottle guide rails 45 and 46 are preferably adjustably secured to the platen I5, and are slightly raised above the rubber mat 42 so as not to interfere with the proper flexing action thereof. A clamping lever 41 is situated at each` end of these guide rails, and as more particularly illustrated in Figure 4, this lever is pivotally secured by means of a cotterpin 48 to a bolt 49 extending through a slot 50 in the platen I5. A resilient rubber washer 86 may be disposed between the head of the bolt 49 and the under side of the platen I5 for resiliently cushioning and improving the operation of the clamping lever 41. Raising the free end of the clamping lever 41 loosens the end of the guide rail to which the lever is attached, and thus permits the guide rail to be quickly adjusted to any desired position, at which point by merely snapping down the clamping lever 41, the guide rails may be reclamped in their newly adjusted position.

A roll bearing carriage 5I is movably guided in predetermined spaced relation above the platen I5 by means of two spaced pairs of crossed arms 52, 53 and 54, 55. arms 52, 53 and 54, 55 are each pivotally secured at fulcrum points 56 and 51 to a pair of spaced upper links 58, 58, and are pivotally secured at fulcrum points 56a and 51a to the base I6.

A pressing roll 59, which may be of the type indicated in Figures 2 and 8, or which may be of any other shape, as for instance, that illus trated in Figures 6 and 7, (the choice thereof depending upon the outline of the bottle upon which the label is being axed) is rotatably supported by means of a shaft 60 and bearing blocks 6I housed within the side walls 62 and 63 of the carriage 5I.

The manner in which the bearing blocks 6I are supported by the side walls of the carriage is illustrated in Figure 5.

A plurality of bearing block springs 64 are housed within a vertical channel 65 of U shaped cross section, secured to the inner side of the v side wall 62, and these springs 64 may be fixed in relation thereto by means of a cotter pin 66. The rectangular bearing block 6I is adapted to slide within the channel 65 against the pressure of the coil springs 64. The bearing block 6I is adapted to be rapidly inserted into the open lower end of the channel 65, and may then be locked therein by means of a pivoted lever 61 which is swingable into a position obstructing the free lower end of the channel 65. The lever 61 is held in its bearing-block-conning position by means of a flat leaf spring 68 which is fastened to the side wall' 62, and which leaf spring has a hook-shaped extremity 69 adapted to engage the under side of the free end of the lever 61.

The roll 59 may be readily and rapidly removed and another one inserted in place thereof the block. This ejecting action is duplicated on f the opposite bearing block, and the roll and associated blocks are accordingly ejected. A different roll combination may now be inserted in lieu of the ejected roll combination. Each bearing-block of this new combination may be locked These outer pairs of crossed in position by merely raising the free end of the lever 61 until the hook portion 69 of the flat leaf spring 68 rides over the incline 'I0 on the lever 61 and snaps into position on the underside thereof.

In order that the roll and its shaft maybe free to deflect yieldably in a direction perpendicular to the upper link 58, the inner face of the channel member is provided with a slotted portion at the lower extremity thereof as shown in Figure 5.V

The axis of the roll 59 is adapted to move in a path generally parallel to the upper surface of the platen I5. In the extreme position of the roll 59, shown in dotted lines in Figure 1, which is the starting point in the label affixing operation the member 1I, which may be a part of or secured to the upper link 58 acts as a stop by contacting the upper extremity 'I2 of the crossed arm 52. A handle I3 is grasped by the operator when the carriage is in the extreme initial position indicated by dotted lines in Figure 1 and moved in the direction of the arrow 73a. The common link 58 which was in a nearly vertical position now shifts to the approximately horizontal position indicated in full lines in Figure 1 and continues its movement until in its iinal position it is again in an approximately vertical position. Reversing this operation will bring the carriage back to its initial position. Throughout the foregoing motions of the carriage, the axis of the roll moves in a path generally parallel to the platen I5.

If desired, the path of the roll axis may be slightly sloped or inclined with respect to the platen I5 (and therefore with respect to a bottle carried on said platen) by slightly shortening the length of the cross arms 53 and 55. The path of the axis of this roll is most nearly parallel to the surface of the platen I5 when the crossed arms 52, 53, 54 and 55 are all of equal length.

A slight downward slope or lead to the path of the axis of the roll in the direction of forward movement thereof is sometimes desirable for effecting a label-pressing operation. Thus, a slight lead tends to increase the labeling pressure as the roll advances, and this in turn tends more firmly to propel longitudinally any air pockets, excess moisture or paste that may be present between the label and the bottle. Thus, as illustrated in Figure 8, the path of travel '50a of the axis of the roll bearing shaft B9 may be given a slight slope with respect to the surface of the bottle being labeled. This eliminates any tendency the label might have to wrinkle when being aiiixed. It is to be understood, however, that crossed arms of equal or of slightly unequal length may both be satisfactorily employed.

Moreover, maximum pressure may be applied tothe center of the label, with a gradually decreasing pressure laterally on either side thereof when the label is being applied to a crowned bottle surface such as illustrated in Figure 8. The resilient label-pressing roll 59 is maximumly displaced by the crest of the bottle surface and minimurnly displaced at the edges of the label, thus providing such pressure variation in a lateral direction from the center outwardly. Thus, the labeling pressure is highest at the meeting point of the two transverse arrows 19a and 19h, and gradually decreases from this point transversely in either direction. This variation in labeling pressure serves to expel any excess moisture and paste in a lateral direction, and thereby assists in eliminating wrinkles in the label.

In those instances where the surface of the bottle is not centrally crowned and does not readily lend itself to the aforementioned pressure varia` tion, the form of the label-pressing roll 59 may' be altered by providing a suitable annular pro-V tuberance or protuberances which, when rolled' over the surface of the bottle, will still achieve this same lateral pressure variation.

The present vinvention also contemplates the application of labels to bottles, containers, cans, or even solid products themselves, wherein the surface upon which the label is to be affixed is generally not parallel to the platen I5 and the base I6, but is inclined with respect thereto; the respective planes of said surface and said platen or base forming, when extended, an acute dihedral angle. `In such cases the roll-supporting carriage 5I may be readily displaced with respect to the center of its supporting link 58 by means which will be more fully described hereinafter, and such displacement tends to similarly incline or slope the path of travel of the axis of the roll 59. Thus, i

as is diagrammatically illustrated in Figure 10 (wherein the crossed arms 52 and 53 are of equal length), when the axis 60 of the roll 59 is aligned with the center of the upper link 58, the path l of travel 60a of the axis 59 is generally parallel to the base I6. While the precise theoretical path of travel 60a, shown in Figure 10, may not follow the straight line there indicated, it is to be understood that the path of travel is shown parallel to the base I'Ii for the purpose of distinguishing the path of travel shown in Figure 10 from that shown in Figure 9. Thus, the path of travel shown in Figure 9 assumes a distinct slope or lead relative to the base I6, whereas the path of travel shown in Figure 10 possesses no such distinct slope or lead. In this Figure 10as Well as in Figure 9, the links are shown in the inter mediate operative position in full lines and these links are shown in their initial and in their final positions in dashed-dotted lines; the path of travel described by the upper ends of these links. being shown in dashed lines.

When the path of travel 69a of the axis 60 of the roll is to be given a sloping or inclined path with respect to the base Iii, in order to make possible the proper afxation of a label to a similarly sloping or inclined bottle or container surface, the axis 60 may be displaced or offset from the center 85 of the common link 58. Thus, as is illustrated in Figure 9, a slight displacement of theaxis 60 of the label-pressing roll tends to slope or incline the path of travel 59a of this axis 60 with respect to the base I6 and a correspondingly greater displacement of this axis would result in a correspondingly increased inclination or sloping of the path of travel.

In the foregoing discussion the bottle or container was at all times considered to be relatively stationary `with respect to the ground and the label pressing roll 59 was moved relative to this bottle or container. If desired, the roll may be held relatively stationary with respect to the ground and the movement instead imparted to the bottle or container. Y

In the initial or starting position of the labelpressing roll resilient means may be provided for accommodating bottles of a diameter greater than that which could be normally accommodated were the carriage 5I rigidly secured to its supporting links 58. Thus, the side walls 52 and 63 of the carriage 5I may be slidable along, and yieldably mounted on, the upper links 58 by means of coil springs 14 housed Within suitably deformed plates 83 secured to the side walls 62 and 63 of the carriage 5I. These coil springs 14 may be fastened at one end through a block 82, an adjustment screw l5 and a lug 8l to the link 58, the other end thereof being fastened to the side wall 62 of the carriage 5| through the pin 84 in the plate 83.

This construction not only enables the roll bearing carriage 5I to be offset with respect to the center of the upper link 58, to accommodate bottles of sloping contour, but this construction also provides an added resilient accommodation for bottles of varying diameter.

The added resilient accommodation, afforded by the foregoing construction, is intended to enable the operator to insert bottles of slightly larger diameter than those which ordinarily could be accommodated for any particular setting of the platen I5 were the carriage 5I immovably secured to the upper links 58. The axis of the roll 59 is thus enabled (by means of the sliding action of the roll bearing carriage 5l on the link 58) yieldably to move in a direction parallel to the link 58 when the roll is approximately in the initial position shown in dash-dotted lines in Figure l. During the intermediate travel of the carriage 5I (indicated in full lines) the ax'is of the roll 59 may yieldingly move in a direction generally perpendicular to the common link 58 as hereinbefore described, and in so doing the coil springs Ed are compressed. The movement of the axis of the roll 58 relative to upper connecting link 58 may thus assume a direction either perpendicular to or parallel with this link 58, or any direction therebetween. Thus, the axis of roll 59 may yieldingly move at any angle relative to the upper connecting link 58 by virtue of the combined yielding action of springs 64 and 'UL This compound motion of roll 59 relative to the upper link 58 would ordinarily occur when roll 59 entered those phases of its travel dened by its mid-position, illustrated in full lines in Figure 1, and either of its two extreme positions relative to the container being labeled. The foregoing yielding movements of the roll 59 also enable the labeling machine to press labels onto bottle or container surfaces which may beV slightly irregular or uneven,

The bed plate I may be provided with legs of unequal length, as indicated in the drawings, so as to impart a definite slope to the platen l5 and thus enable an operator more easily to guide a bottle into its operative position on said platen.

Two alternative rolls that might be used are indicated in Figures 6 and '7. The one shown in Figure 6 is adapted to be used with bottles having substantially flat labeling surfaces. Figure '7 illustrates a roll that very readily adjusts itself to various shaped containers by reason of its extreme flexibility. It consists of two end discs l5 and 'VI permanently affixed to the ends of a short length of rubber tubing 18. These end discs 'it and 11 are keyed to the roll-bearing shaft 60.

In operation, a front label li! and a back label 80 may be spotted or positioned on the respective front and back label-bearing surfaces of a bottle or container I4, and the bottle or container may then be guided into position with the back label resting upon the resilient rubber pad 43 carried by the platen l5. The bottle guide- rails 45 and 46, the Vertical end stop 46 and the bottle neck guide member 4I all aid in guiding the bottle into its correct position on said pad 43. The handle i3 is then moved in the direction of the arrow 13a (Figure l) causing the label-pressing roll 59 to be passed over the bottle or container and directly press the upper label 19 to the bottle and at the same time apply labeling pressure through the bottle I4 to the back label 8G disposed between the resilient sponge rubber surface 42 and the back of the bottle. The path of travel of the axis of the roll is normally generally parallel to the upper surface of the bottle or container, and may be regulated by the adjustment screw mounted on the upper link 58.

The hereinabove described embodiment of the present invention may be used equally advantageously when axing only a single label to a bottle or container. In such case, the sponge rubber layer 42 may be eliminated and the'bottle or container supported directly upon the platen I5. This sponge rubber layer 32 may, however, be preferably retained at all times regardless of whether or not a plurality of labels are to be simultaneously applied, so that when a simultaneous application of both front and back labels is desired, time need not be spent by the operator in applying this resilient layer 42 to the platen l5.

The machine forming the subject mattei' of the present invention may also be power driven instead of manually operated; the power in this case being under suitable control of the operator.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it is therefore desired that the present embodiments be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.
