' label to uneven surfaces or over the joints between the several sections of cigarette and tobacco boxes and the like. While my invention is generally applicable to box making and labeling machines,

the joint ot the box while the adhesive on it is especially adapted for use in connection with those types oi machines wherein means are employed 'for gumming the labels and initially applying the same to the boxes9 though l would have it expressly understod that l in no wise, limit :myself to such specific application or embodiment of my invention. which l have selected as a basis for illustrating and describing my invention, merely for the purpose of rendering a clear and comprehensible undelstanding of the scope and novel `features thereof..

tv/'ly invention broadly comprehends the provision or arrangement of elastic means for direct impingement with the box and against the previously gummed and initially applied label, strip of material or otherwise, and a construction of such meansV which. will act to immediately receive the boxes as they are fed from a labeling machine., box making machine or the like or both when used in conjunction with each other, as long as Ways are provided for, whereby the labels of the boxes when discharged from such type of machine will be rather moist; said elastic means being universally yieldable and designed so that when engaged with the box or work to be operated upon, its elasticity will be taxed and the same made to adapt itself to any irregularities, inconsistencies of construction or uneven surfaces of the box such as those which are commonly apparent at the joints between the body portions of the boxes and the mating cover sections thereof and thus incident to the taxing of the elasticity of said means to effect a. linal and perfect application of the labels to the boxes over the mentioned joints and various inconsistencies in the surfaces thereof.

This above described arrangement and functioning becomes necessary where the label constitutes the hinge for the cover section ot the box as l have found thatV many, if not most ot the troubles to which such machines are subjected arise through titl) the fact that heretofore, no means are provided to my knowledge, which will automatically conform to the irregularities in the surface ont the box and permit of a full application of the label or hinge strip over the label is in a moist state and at the same time exert a constant pressure against the label for an appreciable length oi" time.

l shall now proceed to describe one einu bodiment of the invention with reference to the accompanying drawings, which show a specilic application thereof, and then proceed to point out with more particularity, the essential elements of novelty in the annexed claims.

In carr in the invention into ractice, use is ma e o a conveyer which is esigned to constitute a grasping and pressing means for the boxes and means for arranging the boxes in a continuous row formation. This mechanism consists of an elastic and expansible runway 15, Whichis defined by endless conveyer belts 16 and 17. These belts are arranged side by side in the same general horizontal line with each other 'and each consists of inner and outer plies of materials 18 and 19 which are separated from each other relatively by an intervening space 20. In the space 1f, arranged an elastic or expansible core or substance 21 such as spongerubber so that the working surfaces of the belts are universally pliable and elastic.A

Any suitable cushioning agent can, however, be employed in lieu of sponge-rubber without involving departure from my claims. The arrangement is also such that the runway 15 between the belts is elastic or expansible so that when boxes are fed between the belts the elasticity of the latter will be taxed to thereby cause the same to be advanced with pressure against the sides of the box. The arrangement is as though the box to be operated upon was held between the thumb and index finger of the hand and pressure of the fingers exerted against the sides of the box to cause that intimacy of contact between the box and the label or hinge strip that is necessary to effect a uniform contact of the label and permit the latter to adapted itself to all present or existing inequalities in the surface of the box.

These belts are superposed with respect to a supporting frame 22 and as illustrated, such frame includes parallel side ba rs 23--23 and suitable end members 24 and 25. At the outlet or discharge end 26 of the runway 15, the supporting rolls 27 of the belts 16 and 17, are respectively mounted upon verticalA shafts 28 and 29 having their ends mounted in bearings 30 of brackets 31. These brackets are provided with cylindrical portions 32 which are arranged to slide upon rods 33 which are supported in the bracket 25. Set screws or similar retaining devices 34 on the portions 32 are adapted to engage with the mentioned rods 33 so as to hold the rollers 27-27 fixedly spaced apart when the desired adjustment of the runway 15 has been obtained.

At the intake end 35 of the runway, the rollers 36-36 are respectively mounted upon shafts 37 and 38. These shafts are arranged in bearings 39 upon brackets 40-40. These brackets are provided with cylindrical portions 41 which are free to slide on transverse rods 42. lSet screws or equivalent fastenings 43 on said portions 41 are adapted to hold the brackets 40-40 in relatively fixed positions. Each of the shafts 37 and 38 is provided with a bevel gear 44 which are arranged in meshing engagement with bevel gears 45 on a power transmitting shaft 46. rlhe gears 45 are adapted to slide upon the shaft 46 when it is desired to change the adjustment of the belts 16 and 17. Ordinarily, they are held fixed upon the shaft by set screws 47.

The shaft 46 is provided with a ratchet wheel 48 which co-acts with a rocking dog 49 which is arranged to be controlled by a link 50, the latter having connection with a crank arm'51 on the shaft 52 of a box feeding mechanism 53. Power is adapted to be transmitted to the shaft 52 by means of a reciprocating bar 54 which may be connected in any suitable Well known manner with a box making machine or otherwise.

The box feeding mechanism 53 at the inlet end 35 ofthe runway 15 comprises the mentioned shaft 52 which is provided with a plurality of lifting fingers 55 which are adapted to be rocked or oscillated when the shaft 52 is in motion. rlhese fingers work between box guides 56 which extend from fixed 'bracket plates 57. The machine is adapted to be arranged with its intake end in receiving proximity with the discharge end of a boxv making machine so that the boxes as they are discharged singly from such machine will be deposited upon the 'fingers 55. 1n View thereof 'it is manifest that when the shaft 52 is rocked in one direction, the boxes are adapted to be sucsively introduced to the runway 15 for direct impingement against the inner leads of the mating belts 16 and 17.

Supported by the frame 22 are horizontally disposed bars 58 on wh'ich are mounted sliding frames 59 which support tensioning rolls 60. rilhese frames are adapted to be moved sidewise relatively of the inner leads of the belts 16 and 17 so that the rolls 60 can be pressed against said leads of the belts and thereby form a relatively fixed backing for saidv leads in order that the elasticity of the runway will be taxed on the introduction of the boxes thereto. r1`he frames 59 are provided with brackets 61 having elongated slots 62 therein. The bars 58 are provided with set screws 63 which pass through the slots 61 'and which are therefore arranged to hold said brackets in fixed positions. The brackets 40-40 are provided with suitable extensions 64 in which tensioning rolls 65 are mounted. These rolls are arranged in the same general line with the rolls 60 and are also adapted to bear against the inner leads of the belts 16 and 17.

The machine herein described is intended to operate upon 'boxes of the character shown neoaiaa at 66 in Figs. 1 0 and 11 wherein use is made of a cover section 67 and a body section 66.

gummed and initially applied to the box before the latter is introduced to the runway 15 and subjected to the action of the belts 16 and 17. After the label is applied and the I x conducted to the runway, while in an upright position, the portion 71 of the la'bel or hinge strip is brought to bear against the next adjacent belt and incident to the elastic or expansib-le action thereof, it will, be observed on reference to Fig. 10, that the belt will automatically accommodate itself to vthose irre ularities or inconsistencies in the surface o the box and thereby cause-said portion 71 to be uniformly brought into close contact with the companion sections of the box. To m knowledge, this method or arrangement ofy providing means which is automatically elastic and universally flexible is new in the art. In practice, I find that best results are obtained by initially adjusting the runway so that in width the same is slightly less than the width of the box to be operated upon in that when the box is in position between the inner leads of the respective belts 16 and 17, the elasticity of said leads will `be immediately taxed. By backing the inner leads by the rollers 60, sufficient pressure of the leads can be applied against the box to satisfactorily advance the same into close contact with all irregular surfaces.

In the form of runway shown in Fig. 9, provide belts 7 0 and 71,', the former being formed of a single ly of material and the latlter being preferably of the same desi as the one previously described herein. rt may be preferred to provide the belt 71 with spaced cleats 72 which are designed to engage against the body portions 73 of those forms of boxes in which the cover sections 7 4f are extended beyond said body portions.

tIn the form shown in' Fig. 8, the belts 75-7 5 are identical in construction with the preferred embodiment of the invention except that each is provided with spaced cleats 76.
