separated standards 16 and 17 for supporting the glue-applying rolls A, B, C, and D1 These glue-applying rolls are preferably arranged so that one or more applications of the substance or glue from t-he tank Will be made by them to a blank passing through the machine. Furthermore, they are all preferably supported so that they tend to gravitate towardthe distributer roll and so that they are freely movable toward the roll or away from it. We also prefer to provide means for nicely regulating or adjusting the position of the glue-applying rolls with respect to the distributer roll so as to regulate the distance of the glue-applying faces of the rolls from that of the distrihuter roll. In this way the faces of the rolls may be made to nearly contact without pressing each other and a very nice regulation is obtained for the coating of glue which is conveyed from the distributer roll to the glueapplying rolls. In order to accomplish this, We prefer to arrange the glue-applying rolls in pairs such as the pair A and B. These rolls are preferably formed with separated glue-applying faces 19"IL and 19", the former being on the roll A and the latter on the roll B. These glue-applying faces are arranged out of alinement with each other and the rolls are arranged relatively close together with the collars of one roll intermediate the collars of the other roll so that the glue-applying faces of one roll extend beyond the glue-applying faces of the other roll of that pair, that is, if the rolls are viewed in end elevation, their peripheries apparently intersect.

Beyond the rolls A and B are provided means for completing the coating operation which is commenced at these rolls. This means operates to coat any spaces left uncoated by the rolls and may apply a second coat over part of the area of the blank. For this purpose, in the present embodiment, in addition to the rolls A and B, We have illustrated two other rolls C and D which form a cooperating pair. These rolls are similarly constructed and similarly arranged to the rolls A and B. There may be as many of these. different pairs,l of rolls as desired. Each pair of rolls coats any uncovered gap left by the other rolls, and preferably suh-v stantially coats the entire surface of the blank.

The rolls C and D are arranged with their glue-applyingv peripheral faces 19c and 191 out of alinement with the glue-applying peripheral faces of the rolls A and B. This arrangement is preferable because it .insures the complete application of the glue to the blank. The desirability of this arrangement appears very clearly froma reference to Fig. 4, in 1which the glue-applying faces are represented as being the peripheral faces of collars 20, formed integrally on the rolls.

By arranging the rolls C'and D so that they do not aline with the other rolls, the glueapplying faces 19c ofthe roll C are in a position to apply a coating of glue along the lines of the adjacent edges of vthe glue-appyling faces 19i and 19h. In this Way, the second pair of rolls is made to apply a. second coat and applies that coat in'proper position to till up any gaps which may possibly be left by the first pair of rolls. In order to support the rolls the standards 16 and 17 are preferably provided with open sockets 21 and these sockets receive and guide the ends of the shafts 22 of the glueapplying rolls. The glue-applying rolls are 30 all preferably positively driven and this may be accomplished by means of a long faced gear wheel 23 on the shaft 14 (see Fig.

2) and meshing with pinions 24 rigid with the shafts or gudgeons 22, and the ends of 35 the shafts of these rolls simply rest freelyi in the sockets (see Fig. 3). It is evident from an inspection of Fig. 3 that the pinions 2& would interfere with each other unless they were arranged out of alinement with each other, as indicated in Fig. 2. We prefer to provide means for simultaneously adjusting all of these rolls A, B, C and D. For this purpose We prefer to provide a cam 25 which is adjustably supported on 95 the axis of the shaft 1t, and this cam has a plurality of cam edges 26 which en- -gage respectively with the shafts or gud- 'geons 22 of the different rolls. This cam is duplicated at the other end of the machine and evidently by rot-ating these cams in one direction, the rolls could all be adjusted inwardly, yWhereas if the cam rotated in the opposite direction, the rolls would all be adjusted outwardly. Each of these cams 25 105 has a Wing with a slot 25a which receives a clamping stud 25 secured in the frame. By means of these bolts the cams can be clamped in'any adjusted position desired. All the glue-applying rolls, however, constantly tend to gravitate toward the distrihuterV roll'and so that their glue-applyingl faces tend to come into contact-With the peripheral face of the distributer roll.

Between the rolls A and B, We prefer to provide means for coperating With the rolls 'to assist in guiding the blank through the machine. This guiding means is preferably in the form of a small presser roller V27. This roller preferably has a plurality of 12.0 equidistant circumferential ribs 28, and at each end of the roller enlargements or heads 29 are formed which roll on and are Y supported on corresponding enlargements or heads 30 on the rolls A and B (see Fig. 2). 125 This arrangement operates to hold the presser roller at a'suitable distance from the glue-applying faces of the rolls A and B, that is, so that the peripheries of the ribs 28 lie very near but do not touch the glue-aparrangement for guiding plying faces. We prefer to adopt a similar the blank as it passes from'the roll C to the roll D, and this guiding means preferably comprlses a presser roller 31; the details of the construction and arrangement of this roller 31 are the same a-s'those just described in connection with the other presser roller.

Between the rollers B and C,we prefer to provide a presser roller E which is of relatively large diameter and of considerable weight, and the ends of this roller are provided with circularheads or wheels 32 which roll upon the coperating heads 30 on the ends of the rolls B and C, and this operates to impart the weight of the roll E to the rolls B and C, at the same time holding the Vcircumferential ribs 33 of this roller out of contact with but adjacent to the'peripheral faces of the rolls B and C. In order -toY may, if desired, be attached in common to a bar 35. 'These fingers are preferably of substantial ,U-form, the bend of the VU being disposed toward the roll B from which the blank is received, and the free legs of the U projecting toward the roll C, and in such a way that they will operate to strip the blank ofi' of the glue-applying surface of the roll B and direct it against the surface of the roll C. For this purpose, the forward ends of the guide lingers 34 preferably Aproject inwardly beyond theperiphery of the roll B. Similar guide fingers 36 are provided for talng the blank oil' of the surface of the last roll D and these fingers 36 direct the coated blank onto the upper run of an endless conveyer 37 which conveyor is supported on a conveyer frame 38 which extends out over the tank 11. This con- Veyer preferably consists of aplurality of belts 37 guided around suitable pulleys 39 and 40 supported on this frame. The frame 38`is preferably supported on the frame 10 on a suitable pivot 41, enabling it to be swung up when desiredf The pulleys 39 are carried on a common shaft 42 driven continuously when the machine is in operation .by means of al gear 43 at its end, actuated by gears 44 and 45, the latter of which meshes with the aforesaid gear 23. We provide means to prevent the coated blanks from curling up at their edges. Above the belts 37 a plurality of narrower belts 46 are provided which are to .keep the gluecoated blank'fromcurling up.. These belts run substantiallyv parallel with and near the belts 37, their lower ends passing around pulleys 47 on a common shaft 48, and this shaft 48 is driven continuously by a gear 49 on shaft 42 which meshes with the gear 50 on the shaft 48. While the coated blanks are lying on the conveyor 37 they have their glued slde down. As each blank passes V,lower 15 to the glue-applying rolls.

around the pulleys 40, it is stripped olf the belts 37" by suitable guides 51 (see Fig. -1) and each blank then falls down onto an 1nclined shelf or delivery table 52.

When the gluing machine is in operation, it is usually run in conjunction with another machine such as a wrapping machine which is being fed with the glued'wrappers. The operator of such machine constantly removes each glued blank as it arrives at the table 52. The wrapping machine and the gluing machine are both controlled by the operator of the wrapping machine so that when the wrapping machlne stops, the gluing machine also stops and this arrangement prevents any possibility of two or more wrappers arriving on the delivery shelf 52 at the same time and so that they could become stuck together. If necessary, the belts 46 may have a special form particularly adapting them to their purpose. For instance, we may employ coiled wire belts, the coils of which tend to prevent the curling edges fropi slipping by when they are trying to cur The wallower roller 15 is preferably hung on tsgudgeons 57 between two arms 54 and these arms are mounted to swing on rotating pivot pins 55 at the sides of the tank,

.and are adjustable on said pivots by means of adjusting screws 56. The gudgeons 57 of the roller 15 are about on a line between the pivots 55 and the shaft 14 so that by swinging the arms 54 upwardly the roller 15 can be swung out of the tank and also out of engagement with the distributer roll 13 which conveys the glue from the WE1- y swinging the frame 38 upwardly, the rolls C and D as well as' their adjacent roll 31 will be exposed so that they can be readily removed from their bearings, if desired.

The sheets or blanks 58 which are to be coated with glue are preferably supported in a pack 59 with the sheets 58 on edge ('see Fig. 1). The ymechanism for supporting this pack and for oscillating the pack so as to present the foremost sheet to the glueapplying roll A is covered in Patent No. 1,152,358 dated August 31, 1915. This feeding mechanism will now be briefly described :y

It comprises an inclined table 60 which is provided with a rack 61 which is reciprocated by means of a cam 62 on acam shaft 63. The cam operates a rock-lever 64, the short end. of which isconnected at 65 with the rack 61. A spring 66 tends to pull the rack outwardly on the table and in a direction to'hold the roller v67 of the lever 64 against the cam62. The connection at 65 is a pin and slot connection. Back of the pack 59 there is mounted a follower or pusher 68 preferably comprising a base or slide 69 mounted to travel inwardly along the table. 0n the base 69, is pivoted a gear las j There ore, this upward movement of the j rack will pull the gear wheel 70 and the base wheel and a-pawl carrier 71, said pawl carrier having a pawl 72 which-engages the teeth of the gear wheel 70. As the rack 61 moves in an outward direction on the table,

it moves the gear wheel -70 in a right hand..

which is pivotally mounted at 74 on the basev 69, the said awl carrier bein connected by a link 75 wlth this plate. o eration of the machine this late 73 simp y oscillates on its pivot 74. I the forward oscillation of the plate should be excessive such as that indicated in Fig. 1, the yend of the pawl 72 comes out of en agement with a latch 76 and then frees itsel automatically from the teeth due to the special construction of the nose 77 of this awl. When this occurs the plate 73 falls ack toward the left, as viewed in Fig. 1 and the pawl 72 gets a new engagement with the teeth of the gear. As the pawl 72 moves back with the plate 73, it engages the shoulder 78 of the latch 76 andpushes this latch back against the resistance of its spring7 9, and the latch is then moved back into its normal position by its spring, pushing the awl 72 mto engagement with the teetho `the gear wheel.

In this way the pawl automatically takes a newv grip on the gear 4wheel if the plate 73 has an excessive forward oscillation. In ad' dition to this there is provided a'detent pawl 80 which is mounted on the base and pressed into engagementwith the teeth ofthe gear wheel by a spring 81.1,"'If suchen excessive movement of the oscillating plate 73 occurs, such as just described, a tooth of the gear wheel 70 will move ast the pawl 80 and the pawl will prevent t e gear wheel from re-A turnin when the rack'6 moves upwardly.

69 upwardly on the inclined table. In order to prevent the pusher from slipping back on. the inclined table and for holding th ground gained `in the upward movement given toV 1tV by the rack, we provide a ratchet rack 82 with inclined teeth and we also ro vide a pawl Y83 which meshes with t ese teeth and prevents the base from slipping back. Thispawl is pressed into en agement with the ratchet rack by a suitab e spring 84. The rack 61 is suitably guided by pin and slot connections 85 on the under side of the table.V

In order to adjust the height of the pack with relation to the roll A, we prefer to provide a manually operated adjusting screw 86 which passes through a threaded sleeve or nut 87 attached to the table 60. In order'to maintain ,theiengagement with the cam 62 on the shaft 63, the cam 62 is arranged to slide along dn the shaft 63 n the normal through the medium ,of a feather running in a slot 87 in the cam shaft. An adjustable stop 88 is provided for limiting the forward movement of the pawlcarrier 71.

In order to e'ect a uniform ydistribution of the glue on the distributer roll 13, we prefer to constantly shift that roll longitudinally to and fro on the Wallower 15. In order to accomplish this movement in a simple manner, we prefervto provide a gear cam 89,`the `rim of whichv is warped out of its proper plane and thus constitutes a cam (see Fig. 2) so that the edges of the rim operate upon a grooved roller 90 fixed to shaft 14, and shift the shaft longitudinally in its bearings. At the same time the gear teeth on the rim 89 mesh with corresponding gear teeth 91 at the bottom of the grooved roller 90 so that this cam gear not only a'ords means for shifting the shaft 14, but also affords means for rotating By reason of the long face or gear 23 driving engagement is maintained with the pinions 24. 1

In order to support and guide a pack 59 of the sheets on one edge, we prefer to provide a guide rod 92 which is suitably supported in an adjustable bracket 93 on the` table, and this guide rod paes through a suitable slot 94 in the oscillating plate 73.

The c am shaft 63 is preferably continuously driven by a shaft 95 which aetuates it through suitable bevel gears 96.

When the gluing machine is in operation,

the operator starts the gluing machine and also starts the feed movement from the peck-` from thepack.u The foremost Vsheet adheres to the Troll` A and rolls up on it so that the upper edge of the foremost blank orsheet passes under the guide roll 27 and is then guided onV through the machine sol that the blank /will pass on through the machine and between the

belts

37 and 46.
