The object of my present invention is to devise a novel gluing machine in which conventional tight wrap gluing can be accomplished by means of a conventional gluing roll which can be replaced by a novel stencil roll so that the same machine can be employed for the conventional gluing of wraps and for stencil work.

A further object of the invention is to devise novel means for actuating a novel construction of a gluing roll whereby the stencil mechanism will be operated at the proper time to effect the transverse gluing of the wraps.

A further object is to devise a novel roll which will continuously effect the longitudinal gluing of the wraps and intermittently effect the transverse gluing of the wraps.

In this art, as heretofore practiced, it has been deemed necessary in stencil work, to employ a separate and independent fiat stencil machine, and the stencil machines have been constructed in such a manner that it has been impractical to combine them with a wrapping machine without materially slowing up production.

A further object of my present invention is to devise a single machine which can be employed for stencil work and also for conventional gluing, which will feed the glued wraps directly to a wrapping machine in such a manner that the wraps can be conveniently handled in a minimum of time by the operator of the wrapping machine.

With the above and other objects in View, as will hereinafter more clearly appear, my invention comprehends a novel gluing machine adapted for both conventional gluing and for stencil work.

It further comprehends a novel construction and arrangement of a gluing roll in which the gluing roll is driven in a novel manner, and wherein the paster feet carrying portion of the roll can be controlled in such a manner that the paster feet will be brought into and out of operation to contact at predetermined times with the wrap which is to be glued.

It further comprehends novel detent mechanism and novel means for actuating it.

Other novel features of construction and advantage will hereinafter more clearly appear in the detailed description and the appended claims.

For the purpose of illustrating the invention, I have shown in the accompanying drawings a typical embodiment of it, which, in practice, will give satisfactory and reliable results. It is, however, to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized, and my invention is not limited to the exact arrangement and organization of these instrumentalities as herein set forth.

Referring to the drawings:

My present machine embodies a number of features which are old per se in the art, such as, for example, the paper feeding mechanism for the unglued wraps and the delivery mechanism for the glued wraps, and I have, therefore, illustrated and described such features with only suflicient detail to enable those skilled in this art to understand the construction and operation thereof.

The driving mechanism corresponds, substantially, to that shown in my prior Patent 1,744,244.

As my invention resides more particularly in the gluing mechanism and I will first describe the stencil mechanism.

I designates the machine frame on which is pivotally mounted the gluing mechanism. A tubular coupling 3, see Figure 4, has a poiygonally shaped aperture 4 at its outer end for operatively connecting it with its driving means in order to drive a paster feet roll 5. 5 is made in sections and is provided at its driving end with a smooth roll 6 having a hub fixed to the driving coupling 3. The paster feet roll 5, at its opposite end, is provided with a smooth roll 1, provided with a hub 8 and gear 24, in which is journalled a shaft 9 retained in position by means of a collar 19. The opposite end of the shaft 9 is of reduced diameter and has a bearing in the tubular connection 3. The tubular connection 3 is journalled in one of the bearing brackets H carried by the machine frame. I The shaft 9 has secured to it by means of a pin l2, a paster feet carrier is which'is provided with the dovetailed circumferentially extending slots !4 adapted to receiv'ecorrespondingly shaped shoes l5 to which the stencils iii are secured by means of fastening devices l1, illustrated as screws in threadedengagement with the shoes l5.

hub 'l 8 of the gluing roll section 6 has keyed to it gear [9, by means of a key 20. The gear lfi meshes with a gear 2| carried by a shaft 22 journalled in the stencil carrier 13 and at its op posite end'it is provided with a gear 23 which meshes with the gear 24 keyed to the hub 25 of the roll section I. The shaft 22 is jonrnalled in the bearing sleeve 26 which is fixed in position in the stencil carrier l3 by means of the pin 21, see

' Figure 4. The gluing roll sectionfi has, in frictional engagement with it, a gluing ring 28 having the raised gluing face 29. In a similar manner, the gluing roll section I has, in frictional engagement with it, the gluing ring so having a circumferential gluing face 3L These gluing rings 28 and 30 effect the longitudinal gluing at the side tudinally of their roil sections to conform with the width of wrap which is being used.

The outer end of the gluing roll section I forms one part of a friction coupling and is recessed to provide a tapered clutch face 32 with which cooperates the tapered portion 33 of the clutch member 34 which latter is slidably'mounted on the shaft 9. The shaft 9 is longitudinally slotted as at 35 to receive a 'shoe 36 which is fixed to the clutch member 34 by means of a fastening device 3'l. A spring 38 is interposed between the forward lug of the shoe 35 and an'arm 39, which extends into the slot 40, and is pinned to the shaft 9 by means of a' fastening device 4|. It will be seen from Figure 4 that the armf39 does gnot extend to the bottom of the slot in the shaft 9 so that the shoe 36 is capable of longitudinal sliding movement between the shaft 9 and the arm 39.

The shoe .36 is provided at its outer end with an.

The slotted end of the shaft 9 is enclosed by a 7 housing 48 having a sleeve 49 extending into the 7 adjacent bearing bracket I l to contribute to form a bearingfor the shaft 9. This housing 48 is apertured to receive a plunger 50, see Figures 6 and '7, connected at its lower end with a cam 5! paster feet roll block and the upper wall of the housing so that the tendency of such springis to move the pawl 53 and the plunger 50 downwardly. The chamber of the housing has one side wall cut away, as at 58, to provide a space into which the pawl 53 can move so that the arm 39 is free to V revolve and thereby the shaft 9 to which it is connected. To prevent the pawl 53 catching on the insert 52 I provide a spring pressed guide having its free end bevelled,'so that when the pawl 53 moves downwardly it will clear the upper sharp edge of the insert 59. The upper L shaped end of the block 55 overhangs a manually controlled member 56 in the form of a bar or strip of material which is provided with a recess 6|, see Figure 7, forming a space into which the hook shaped end 62 of the cam lever 45 can move during the operation thereby releasing the slide 36 sothat the spring 38 can move the clutch member 34 into clutched engagement with the roll section '5. In Figure 4 the hook shaped end 62 rests on the member 56. V a

The controlling member 55 is mounted out of alignment with the plunger 50 as will be clear from Figure 11, and is provided with an out- "wardly extending pin H4 which extends through by limit the downward movementiof the plunger 1 The controlling member 56 provides for the manual tripping of the stop pawl 53 and is controlled by a manually actuated lever 95, fulcrumed at 56 on the machine frame in proximity to the discharge end of the apron 61 which delivers the glued wrap to a wrapping machine or i other desired place of utilization. When the grasping portion of the lever 65 is raised the rod 58, pivoted atone end'to the free end of such lever, rocks thebell crank 69 on its fulcrum l9, see Figure 2, so that the bifurcated arm H which receives the pin I I4 will raise the manually controlling member 56 and thereby the block 55 and the stop pawl 53. The rod 68 is slidable in the guide 72 between which and an abutment 73, on

the rod, is interposed a spring 14 which tends to move the rod 93 into the position seen in Figure 2. The cam 5| is actuated by a pin 15 which, as illustrated, is carried by and revolvesin unison with a. wrap feeding cylinder [6.

The gluing mechanism comprises a glue frame Tl pivotally mounted on post 18 and'provided with a grasping handle 19. The frame 1'! is provided with a glue pot or reservoir 89, and into the glue in such reservoir extends a glue dipping roll 8i suitably journalled on the glue frame H, see more particularly Figure 2. A glue trough 84, openat its outer end, has its lower side contacting with the periphery of .the glue dipping roll 8! and the bottom of such side contacts with the periphery of the glue transfer roll 83 which is journalled in the brackets 82, see Figures 1 and 2. The top side of the trough 84 is movably carried by it and secured in adjusted position by means of the fastening devices 85 so that the space be tween the bottom of the upper side of the glue trough and the periphery of the glue transfer roll can be varied in accordance with the amount of glue which is to pass from the trough through such space to the glue applying roll 5. A squeeze or doctor roll 86 journalled on the glue frame I'I beneath the transfer roll 83 and contacts with the glue applying roll 5; Excess glue is removed from the" doctor roll 86 by means of a scraper 81.

The driving mechanism The driving mechanism is best seen in Figures 8 and 9 and is substantially the same as that shown in the Rider and Saatman Patent 1,744,- 244.

88 is a motor, the shaft of which is operatively connected with a worm 89, meshing with a worm gear 90 fixed to a gear 9|. The gear 9i meshes with a gear 92 keyed on a longitudinally adjustable shaft 93 having its inner end of a polygonal contour, as at 94, to engage the correspondingly shaped recess 4 of the glue applying roll 5. The shaft 93 is moved into clutch or declutched position by means of a manually actuated lever 95.

91 is the feed table, see Figure 2. 98 is the suction pump. 99 is the stripper bar, see Figures 1 and 4, adjustably mounted on the glue frame and provided with the strippers I00 adjustably mounted thereon.

The shaft of the glue applying stencil roll 5, see Figure 10, has a gear IOI fixed to it which meshes with an idler I02, which, in turn, meshes with a gear I03 which drives the shaft of the squeeze roll 86. This gear I03 meshes with a gear I04 on the shaft of the glue transfer roll 83. The shaft of the squeeze roll which carries the gear I03 is also provided with a gear I05 which meshes with an idler I06, which, in turn, meshes with an idler I01 which drives the gear I08 on the shaft which carries the dipping roll 8I. The squeeze roll is journalled in the pivotally supported brackets I09, see Figure 2, which are provided with the adjusting screws II8 so that the squeeze or doctor roll can be adjusted relatively to the glue applying paster feet roll 5.

The shaft of the dipping roll BI is removable by upward displacement from its journal bearings and the same is true of the glue transfer roll 83. The squeeze or doctor roll is provided with a sectional bearing so that such doctor roll may be removed for cleaning or other purposes, and the stencil roll is also provided with a sectional bearing having the nuts I I I, see Figure 2, so that such bearing can be opened and the glue applying paster feet roll 5 can be removed and, if de sired, replaced by a smooth gluing roll of any desired or conventional construction depending on the type of gluing which is to be done.

The feed cylinder 16, see Figure 3, is provided with a radial slot I I2 in which is adjustably positioned a pin II 3 which, when set, in a position corresponding to the fifteen inch graduation thereon, will allow the paster feet to be tripped a second time without pause between the first and second revolution. Pin I I3 remains in a position corresponding to the fifteen inch graduation for all wraps fifteen inches in length and under. This fifteen inch length is the length of wrap which is equal to the circumference of the paster feet roll. It is obvious that for wraps fifteen inches and under two paster feet are used positioned circumferentially apart in the circumferential grooves I4 to suit the length of the wrap.

The second revolution in this case is simply made to allow the wrap to be carried far enough to be completely stripped by strippers I00.

For wraps fifteen inches and over up to the capacity of the machine, only one front paster foot is used, which, when brought into operation by pin I5, will stencil the front end of the wrap, complete its revolution, pause a length of time corresponding to the amount the wrap exceeds the fifteen inch length and then tripped a second time by pin M3 to apply glue to the back end of the wrap.

For this reason, the pin H3 is adjustable and provided with graduations I24, the setting of which corresponds to the length of the wrap to be run.

It is understood that the fifteen inch circumference mentioned is only referred to as an example of the condition that actually exists on the present machine. This will vary according to the circumference of the stencil roll used.

The stencil carrying portion of the glue apply ing roll, see Figure 1, is preferably provided with graduations I25 to facilitate the circumferential adjustment of the paster feet in accordance with the length of wrap which is to be glued.

I have deemed it unnecessary to illustrate and describe in detail all of the features of construction and operation as certain of them are now clearly understood by those skilled in this art and the general cycle is clearly set forth in Patent 0- No. 1,744,244. I, have, therefore, illustrated in detail the paster feet roll and its controlling mechanism which forms more particularly the subject matter of this invention.

The operation will now be apparent and is as follows.

The wraps which are to be glued are placed on the counter weighted table 91. Assuming now that the glue frame TI is in its closed position so that the shaft 93, see Figure 8, is in driving connection with the paster feet roll 5, the wraps will be progressively passed to the feed cylinder I6, being retained thereon by the conventional gripper mechanisms, which are, at the proper time, released in the conventional manner. Each wrap is thus passed to the glue applying paster feet roll 5.

The glue dipping roll 8I feeds the glue from the glue pct 80 into the trough 84 which forms an auxiliary glue reservoir to feed the glue to the transfer roll83 throughout its length.

The roll 83, rotating in the direction of the arrow, has its glue coating cut down to the proper thickness by the adjustable upper blade, adjustably fastened in 84 by clamping screws 85.

This is adjusted to allow the roll 83 to deposit a slight surplus of glue to the stencils and the gluing rings 28 and 30.

Once set, this adjustment need not be changed, but the desired amount of glue on the wrap is cut down by the squeeze or doctor roll 86 rotating in an opposite direction which wipes the paster feet and gluing rings free of the surplus glue.

The scraper 81 is for the purpose of cutting all the glue from the squeeze roll to allow itto present 65 an absolutely clean surface when it comes in contact with the paster feet.

The adjustable gluing rings 28 and 30 are longitudinally adjusted on their roll sections. These rings have a driving fit on their roll sections, so 0 that their gluing surfaces can be positioned in accordance with the width of the wrap which is to be glued, and the glue will be applied at opposite marginal portions throughout the length of the wrap. The paster feet I6 are circumferen- 75 .tially adjusted in their slots l4 in accordance with the length of the wrap which is to be glued so that the transverse gluing will take place at the marginal end portions of a wrap. The glued wraps are delivered to the delivery apron 61. As the feed cylinder 16 revolves, the pin'15 cooperates with the cam 5| to move the plunger 50 upwardly.

The arm 39 is in the form of a tooth rounded at its bottom and terminating in a straightwall which latter is held in stopped contact with the face of stop pawl 53 under the frictional rota- .tion .of the rotating parts 6, and I. The cam 5i operated from the feeding cylinder 16 is moved in an upward direction bringing the bevelled' tooth 52 into engagement with 39 on the shaft 9 to which the, stencil drum I3 isrigidly. fastened by pin I2. By this tooth action the stencils or paster feet are started in a definite timed relation to the wrap on cylinder 1,6; It is evident that this positive motion would haveshort durationso that with a slight continued upward movement the friction clutch 34 is drawn into engagement with the constantly revolving member I bythe hooked shaped end 62 of cam lever dropping into the depression 6| and continuing into such engagement for a full revolution where the clutch is again disengaged by .the contact of end 62 against member 56.

It is evident that when the upwardly moving plunger makes contact with the tooth. 39 the bottom edge of the stop pawl 53 mustbe in a position at the edge of the block 59 toallow it to swing out of the way as the continued upward movement of the plunger 50 starts the tooth 39 rotating the shaft 9.

The purposeof the member 56 with recess 6| is to hold the cam lever 45 in a position towards V I the center of shaft 9, in which position it is holding the clutch member 34 out of engagement with the rotating roll section 1.,

With the upward movement of the plunger 59 the shaft 9, carrying cam lever 45, rotates to a position where the end 62 of the cam lever is in contact with the 'member 56 having recess 6|, drops into the recess 6|, allowing the friction clutch to engage to complete the entire revolution.

It will be apparent thatif the lever65, see Figure'2 is raised, the rod 68 is pushed against lever 69 which turns on its fulcrum 10 and raises pin H4, see Figures 15 and 16. This lifts the parts 56, and 53. 53 isdrawn out of contact with 39,

end 52 of lever 45. This permits spring 38to move part34 into engagement with part 1. As long as lever is retained in raised condition the stencil organization revolves continuously until lever 65 is released. The purpose of actuating lever 65 is to remoisten the stencils in case the machine has been idle for a considerable period. 56 and 53 are withdrawn at the same time and the clutch engages immediately. The lever 65 is only actuated when it is desired to remoisten the stencils.
