This invention relates to machines for applying adhesive to the surface of sheet mate rial such as labels, paper box blanks, paper commodate differing service conditions.

The foregoing and other features of ad vantage are secured in the machine herein illustrated and described, while the appended claims particularly point out the alleged features of novelty.

In the drawings Fig. I is a perspective view of my novel manually operable gluing machine, with a cover element removed to better disclose otherwise hidden details.

Fig. VI isasectional View similar to Fig. II, but incorporating a modified form of picker means, hereinafter fully explained; and v Fig. VII is a fragmentary plan view of the picker means illustrated in the preceding figure.

Referring more in detail to the drawings, my novel gluing machine comprises a rectangularly configured container or tank 8, having a dished bottom 9 provided with feet 10.

This container or tank 8 is formed with a pocket 11', set apart therefrom by an integral T partition 12, and opposed oflfsets 13 having vertically directed slots 14, for a purpose later on explained. Journaledtransversely in the container 8 is a hollow drum or gluing roll 15 which-is journaled for free rotation by means of a bearing screw 16 at one end, and a boss 17 at the other freely passing through a cut out 18 of the partition 12, and fitted with a removable crank handle 19. Integral with, or securely attached to, the gluing roll boss 17 is a spur gear 20 meshing with a gear 21 on the adjacent end of the feed device, comprehensively designated 22. This feed device 22' comprises a spindle 23 having reduced ends, adapted for free rotation in the vertically directed slots 14: of the container offsets 13, that is, conveniently, fitted with a hard Wood or other appropriateroll 24:. having spaced grooves 25 receiving round-section rubber bands 26,v which latter project beyond the perimetric surface of said roll, as clearly shown in Figs. I and IV. q

Referring now to Figs. V and VI, which show a modified form of the feed device 22, it will be seen the same comprises a shaft 27, bearing a series of V-grooved disks 28 maintained' in proper relation by means of intervening spacers 29, which are securely clamped together through the medium of a cotter pin 30 at one end, with a lock sleeve 3-1 and nut 32 at the other end. Obviously the round section rubber bands 26 are snapped into the V-grooves of the disks 28, and it will be apparent that, by releasing the lock' sleeve 31, said disks can be removed for cleaning or renewal of the rubber bands 26, while their number may be varied to accommodat'e different service requirements. Attention is particularly drawn to the fact that" the feed device 22 may be characterized as of the gravity type in that it acts upon the ma-' terial fed into themachine by its own weight, and consequent slight compressio-n'of the rubber bands 26; also, that there is nopull exerted on said material by the roll 15, other than the 1 contact influence of the applied glue, which is promptly released by the picker or stripping means, later on fully described.

Freely pivoted on feed device spindle;

22 is a pawl33 adapted to engage the teeth of the spur gear 20, thereby preventing back motion of the gluing roll 15, in an obvious manner, as will be best appreciated from Fig. II.

,The means for evenly spreading or distributing the glue, conventionally 1ndicated 34 in Figs. II and VI, comprises a horizontally-directed scraper-bar 35 having vertically directed terminal portions 36, pivoted at one end on a pin 37 Fig. III integral with or fitted to an upstanding projection 38 of the partition 12, and at the other end to the reduced terminal of a screw 39, later on again referred to. Co-operative with the scraperbar 35, through the medium of a T-shaped end 40 entering an aperture 41 therein, is a manipulator 42 havingits other end angled at 43 and forked for engagement with the grooved inner end 44 of an adjusting screw 45. Thus it will be understood by turning the screw 45, in the proper direction, that the scraper-bar 35 will be rocked on the pivots 37, 39 towardor away from-the gluing roll 15 and the thickness of the film of glue applied by said roll thereby adjusted.

46 is the feed table or plate which is formed along the outer edge with a curved lip 47 that abuts the complementarily sectioned flange 48 of the tank 8, spring-tongues 49 serving to clamp the same in position by snapping the underside of the relatively reduced part of said flange at 50, in an obvious manner. The feed plate 46 is downwardly inclined along its inner portion and slotted to provide a series of tongues 51 with their ends preferably rounded; which, when said plate is in position, intervene the rubber bands 26 and extend into close proximity with the peripheral surface of the gluing roll 15. It is also to be noted that the terminal tongues 51 of the series freely pass between the vertical extensions 36 of the scraper-bar 35, and thereby serve to maintain the same engaged with the pivots 37, 39. In conjunction with the improved gluing machine, I provide a novel picker or strip ping attachment which functions to promptly detach or release the sheet material from the roll 15, as fast as it is glued. This attachment comprises a spindle or rod 52 having diametrie holes 53 near its ends, whereby it is seated on shouldered pins 54, secured in the tankwalls. Freely supported by the rod 52 are a series of comparatively-thin icker or stripping elements 55, of the conguration best shown in Fig. II, which are maintained in spaced relation by intervening and end sleeves 56, 57, and 58, respec tively; the latter two being secured to the rod 52 bycotter pins 59, in an'obvious manner. Attention, 'however,is directed to the fact that the stripper elements 55 are afforded a small degree of lateral clearance with respect to the sleeves 58; so that, as the gluing roll 15 is rotated, they may slightly vibrate laterally of the machine and thereby prevent the formation of un-glued lines on the material as it leaves said gluing roll.

Instead of the stripper device described in the preceding paragraph I may employ the means shown by Figs. VI and VII, which consists of a plate 60 having a rolled edge and spring tongues 61, analagous to those set forth in connection with the feed plate 46, for gripping the tank flange 62 at the back of the machine. This plate 60 is conveniently provided along its inner edge with spaced fingers 63 that are slightly inclined downwards and formed with upwardly angled picker or, stripping tongues 64 which barely touch or impinge the gluing roll 15, asconventionally indicated in Fig. VI by the dark shade line, and which function to remove the sheet material from said roll, in the manner hereinbefore explained. It is to be noted, however, that the just described form of stripper means is substantially rigid, and better adapted to the gluing of the heavier materials;

65 is a cover plate of arcuate cross-section that is provided with end projections or flanges 66, having slots 67 therein, whereby said plate is mounted over the feed device 22, and clamped to the oifsets 13, through the medium of the screw 39 and a second screw 68, in an obvious manner.

From the foregoing it is thought the use and operation of my improved gluing machine will be well understood, but it may be here remarked that the feed plate 46 is first removed and the tank 8 filled with glue to within about one-quarter of an inch below the spreader or scraper-bar The screw 45 is next adjust-ed until the bar 35 is positioned relative to the applying roll 15, so that the latter carries up a uniformly thin film of glue. The feed plate 46 is replaced and. properly centered so that it does not bind either of the scraper-bar end extensions 36, whereupon the machine is ready for opera tion, by consecutively placing the elements to be glued on the plate 46, and from which they are drawn by the feed device 22 and pass over the roll 15, with subsequent removal therefrom by the strippers 55, or 64.

IVhen it is desired to cleansethe machine, the cover plate 65 is removed by slackening the screws 39 and 68. The feed device 22 is then lifted from its bearings, the stripper means 55 or 64 bodily removed, while the handle 19 and bearing screw 16 are withdrawn, whereupon the gluing drum 15 can be lifted out and washed. Obviously, a reverse sequence of operations takes place in re assembling the machine; and while I have particularly described the illustrated embodiments somewhat specifically, it is to be understood that structural changes or variations in the relative aggroupment of the several co-operative means may be resorted to without transgressing the scope of the appended claims.

Having thus described my invention, What I claim is: r
