Specification of Letters Patent.

Patented June 29, 1915.

Application filed February as, 1914.. Serial to. 821,828.

To all whom it may concern:

Be it known that I, Home J. MoMAoKIN,

a citizen of the United States, residing at.

Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Pasting-Machines, of which the followmg description, in connection with the accompanying drawing, is a specification, l ke characters on the drawing representing llke arts. p This invention relates to pasting machines adapted for applying paste to labels which are to be subsequently applied to cartons, cans, boxes, etc., and the object of the invention is to provide a novel device of this ciras which is simple and inexpensive to manufacture, the parts of which can be readily disassembled, thus facilitating greatly the cleaning of the machine and by which labels can be rapidly and efficiently supplied with a coating of paste, and otherwise to improve pasting machines, all as will be more fully hereinafter described and then pointedout in the appended claims.

Figure .1 is a sectional view through a pasting machine embodying my invention; Fig. 2 is a plan view of Fig. 1; Fig. 3 is an end view; Fig. 4 is a section on substantially the line zva:, Fig. 3; Fig. 5 is a section on substantially the line y-y, Fig. 3;-

Fig. 6 is a fragmentary perspective view of the wiping pad.

The device herein illustrated is of that type which comprises a frame sustaining a paste-receiving reservoir, a pasting roller journaled in the frame and by which the paste is supplied to the labels or other articles to be pasted, a shaft situated above the pasting roller and provided with disks that rest on the roller and which, serve to hold the label against the pasting rollerwhile it is being pasted, and means to operate the roller and disk-carrying shaft.

In the drawings 1 designates the frame ofthe machine which is provided with two end members 2 and which also is formed with a paste-receiving reservoir 3. I will preferably make the frame in the form of a casting so that the end members and the paste-receiving reservoir all form integral parts of the same casting. The end members are each provided with upwardly-direc'te'd extensions 4, each of which is provided with a vertical slot 5, saidslots operating to receive both the shafts of the pastmg roller and that of the disk. The pasting roller is shown at 6, it being provided with journals 7 that occupy the slots 5, and these ournals will preferably be provided with collars 8 to hold the pasting roller against longitudinal movement. A This roller can be operated in any suitable way as by means of the handle 9.

10 designates the shaft which supports the disks 11 that bear on the pasting roller, the ends of said shaft 10 being received in the upper ends of the slots 5. I will preferably provide means for positively rotating the disk shaft 10, this being herein accomplished by providing said shaft with a gearing 12 that meshes with a gear 13 rigid with the pasting roller 6. The frame 1 is so cast that the paste-receiving reservoir 3 is open at the top, and this opening is normally closed by a cover 14 which also constitutes a platform on which the label to be pasted rests as it is fed into the machine. This cover may be held in place in any suitable way as by means of spring catches 15.

In using a device of this sort, the label to be pasted is placed on the platform or cover 14 with the face side up and the side to be pasted resting on the platform, and by turning the pasting roller the label will be drawn in between the roller and the disks 11, and the roller will apply a layer of paste to the back side of the label.

It is desirable that the peripheries of the disks 11 should be kept free from paste in order to prevent their depositing paste on the front side of the label, and to thus keep them clear I propose to use a wiping pad 16 which yieldingly engages the top of the disks and keeps the peripheries thereof free from paste.- This wiping pad is herein shown as made of resilient material, such, for instance, as felt or rubber, and as confined" within a holder 17 herein shown in the form of-a tube whichis cut away or slotted at one side, as at 18, to expose a portion of the pad 16. The pad 16 will preferably be so constructed that it will project slightly through the slot 18 in the holder, and the i edges of the slots act as stops to prevent the pad from being brought against the disks with undue pressure. and-its holder 17 are shown as carried by arms 19 that are pivoted at their ends to the frame at 20, and the pad is yieldingly held against the disks by means of a spring 21 which encircles the pivot screws 20 and en 27 on the end pieces 2 of the frame. By

means of this construction the platform can be swung back out of the way when the past ing roller is to be removed for cleaning or other purposes. This platform is yieldmgly and removably held in the notches 26 by springs herein shown'as part of the springs 21. In other words, the spring wire from which the spring 21 is formed is extended at one end, as at 28, and provided with a hook portion which hooks over the trunnion 25.

The same spring, therefore, operates toholdthe platform in place and also to yieldingly hold the wiping pad against the disks. The springs, however, can be readily disconnected from the trunnions 25 if the platform is to be removed.

. a 29 designates a scraper which is adjustable toward and from the pasting roller and by which the amount of paste carried up by the roller to the label can be regulated. This scraper is shown as pivotally mounted upon pivot pins 30 carried in the end pieces'of the frame, and it is provided with an extension 31 extending through a slot in the frame and engaging a groove .32 in an adjusting screw 33 that is situated exterior of the end piece and has screw-threaded engagement with a lug 34 carried by the frame. By turning the screw 33 up or down the scraper will be swung about its pivots, thus carrying its edge toward and from the periphery of the pasting roller.

One advantage of my construction is that the shaft 10 carrying the disks and the pasting roller can be readily removed from the machine whenever the latter is to be cleaned, for it will be noted that both of these ele ments are journaled in the same open-ended slots 5, and are only held in position by their own Weight and by the pressure of the wiping pad thereagainst. The wiping pad can be readily swung back out of the way after which both the disk shaft 10 and the pasting roller can be lifted from the slots This pad 16 7 and cleaned, as also can the paste-receiving receptacle. This is quite an important item in devices of this class in which a sticky material, such as gum or paste, is used for unless they are frequently cleaned the machine soon gets gummed' up to such an ex tent as to render it unfit-for use.

My device is also well adapted for moistening gummed back labels.= Many labels are supplied to the customer wlththe back already gummed and the operation of putting the label on the box, carton or ackage involves moistening the gummed bac of the label. By filling the receptacle 3 with water or some other moistening fluid, my device can be used for moistenlng gummed back labels.

While I have illustrated herein a selected embodiment of my invention, I do not wish to be limited to the constructional features. shown.

Having described my'invention, what I claim as new and desire to secure by Letters Patent is 1. In a pasting machine, the combination with a frame presenting end pieces and an open-topped paste-receiving reservoir between the end pieces, said end pieces each having an upwardly-directed extension provided with a-single vertically-arranged openended slot extending from the top of the extension, ,of a pasting roller having trunnions which occupy said slots and is freely movable vertically therein, a disk-supporting shaft also journaled in said slots and provided with disks which rest on the pasting roller, a pad holder carrying a wiping pad which rests on the disks, arms pivoted to the end. pieces and carrying the pad holder, springs engaging said arms and yieldingly holding the pad against the disks and a receiving platform supported at one end of the pastingv roller and sustained at its other end on the frame, said springs engaging the platform and yieldingly holding It in position.
