Application'filed June 19, 1.914. Serial lie.

To all whom it may concern:

Be it known that we, JAMES D. REIF- SNYDER and HARRY B. SMITH, citizens of the United States, residing at Philadelphia, State of Pennsylvania, and in Brooklyn, county of Kings, and State of New York, have invented new and useful Improvements in Gluing-Machines, of which the following is a specification.

This invention relates to a machine for applying an adhesive or glue to one side only of blanks or individual sheets.

The invention is closely related to the in- \ention disclosed in Patent Number 726,473, granted to P. S. Smith. In that patent, the construction consisted essentially of two spaced rollers having separated glue applying faces arranged in parallel relation and withthe faces out of line so that the first roller which touched the blank applied the glue to it in stripes or zones, and the second roller also applying the glue, in the spaces between these bands or zones, the result be ing that the face of the blank was completely covered with glue. Above the glue applying rollers there was provided a pair of presser rollers,-the axles of which were mounted in sockets so that the rollers could rise or fall with respect to a horizontal line. In using this machine, the operator held a pack of the blanks in her hands and fed the pack at once through the machine, the pack being suiiiciently thick to raise the presser rollers in their sockets and the weight of the pack and the Weight of the presser rollers pressed the lowermost blank onto the glue applying rollers. As the pack passed out from the other side of the machine, the operator segregated the bottom blank to which the glue had been applied and then repeated the operation just described. In other words, a pack of the blanks was passed successively through the machine in the form of a pack. The presser rollers, of course, did not come in contact with the glue applying rollers, so that they remained clean and did not operate to smear any glue accidentally on the upper face of a pack. A machine such as that just described, while it is useful with the mode of operation just described, necessitates constant labor and attention on the part of the operator. Furthermore, a machine with presser rollers of this kind cannot be used hesive to one side only of a single blank fed through the machine, because, it would be impossible to bring about the pressure on the upper surface of the blank to maintain it in contact with the glue applying roilers, for it is evident that the blank being of paper, is very thin, and if the presser rollers would operate with a single blank, they would necessarily have glue smeared accidentally upon them from the glue applying rollers at times when there was no blank passing through the machine.

principal object of the present inven* tion is to provide a machine which will perform the functions of the machine referred to above, but without necessitating the passing of the pack of blanks through the machine, and having a construction enabling the machine to operate etfectively with automatic feeding mechanism which feeds the blanks time through the machine.

to appiy an adone at a @ne of the diflicuities of accomplishing this object is to insure that a good contact may be maintained between the blank and glue applying faces as the blank passes through the machine One of the objects of this invention is to overcome this difiiculty, and furthermore to insure that in passing through the machine the blank will have the glue applied to it throughout its entire area and particularly at the tail edge, or following edge of the blank as it passes through the machine.

Another object of the invention is to arrange for guiding bianks in such a way as to prevent the smearing of glue on the guides.

Further objects of the invention will appear more clearly hereinafter.

in the drawing which fully illustrates the preferred movement of our invention, Figure 1 is a side elevation of a machine constructed in accordance with our invention. Fig. 2 is a plan, certain parts being shown in cross section and broken away. Fig. 3 is a front elevation of the machine, certain parts being broken away. Fig. 4: is a vertical section through the machine, certain parts being broken away. Fig. 5 is a vertical section, but on an enlarged scale, particularly illustrating the feeding mechanism.

Referring more particularly to the parts,

10 represents the frame of the machine which may be of any suitable construction and armesh with the gear wheel 20 rigidon theshaft 21 of a distributing roller 22, the face of which is in Contact with the Wallower 13 below and in contact abovewith the glue applying rollers 14 and 15', The p're'ferredarrangement is most clearly Illustrated 111 F1 4. The rollers 14 and 15 are formed wit separated glue applying faces 23, and this ei ect is most conveniently produced by forming the glue applying faces on a series of collars 24 on the rollers. As illustrated most clearly'in Fig. 2, the glue applying faces of tliecollars are out of alinemefi't with each other.

Arrangement is provided for guidi g the blanks one by one across the u 'p'er si es of the rollers 14 and 15. In o'rer to accomplishthis, we prefer to provide feed rollers comprising an upper feed roller 25 and a lower feed roller 26,'th'e lower feed roller being preferably formed with collars 27fwl1'ich touch the under surface of the roller 25. We provide means for guiding the blank as it passes from these feed rollers so that it is guided in a direction intersecting theflperipher of the first roller 15 in order to e ct a goo contact between the blanks and the glue applying faces of this roller, and we cause the blank to engage and adhere to the glue on a substantial portion of the periphery' of the roller so that the blank adheresto, and is advanced by the glue applying roller itself andwithout any other roller pressing the blank upon it. In order to accomplish this, we provide guiding means between the feed rollers and the roller 15, preferably comprising a lower guide bar 28 which is disposed parallel to the rollers-and provided with a plurality of strips or fingers 29 which project at right angles to the bar, one extremity of these strips being disposed between the rollers 27 of the roller 26, and the other extremity being disposed between the collars 24 of the roller 15, that is between the glue applying faces of this roller. The upper-edges of these fingers are on a line which intersects the outline of the periphery, as indicated in Fig. 4, so that they tend to guide the blank in a direction intersecting the periphery of the roller.

We provide guiding means on the upper guldlng direction at any side which preferably comprises a guidebar 30 which is substantially parallel with the guide bar 28, and this guide bar has a pluali'ty of strips or fingers 31 which are arranged in a staggered relation in respect to the fingers 29; however, they are disposed parallel with the fingers 29 and their rear extensions 32 preferably terminate very near the glue applying face of the roller and near the plane of the upper edges of the fingers 29. These extensions .32 are preferably rounded on their ends, as shown in Fig. 4. The uide .fin ers 3-1 evidently form a guide for die side 5f the blank which is remote from the glue applying rollers, and the blank has a sliding enga ement with these fingers as it passes onto t e roller 15.

l-fietween the rollers 14 and 15 we provide guiding means having the same general functions as the guiding means which includes bars 23 and 30 tlns guiding means is preferably entirely supported between the rollers 14 and '15 and preferably comprises an upper guide bar 33 which is disposed parallel W' h are rollers 14 and 15, and is preferably su ended from an up er "bar 34 by means of adjustable bolts 35. 5n the under side er this uper guide bar 33 we provide apluraiityo finger-s36 which are preferably thin and flat like the fingers described above, and these fingers extend at right angles to the bar. These fingers are arranged 'i'n line with the glue applying faces of the rear or second roller 14, and the lower ed 'es 'of these guide fingers incline down'war l'y slightly, so that when the blank slides along on their edges it"is guided in a direction intersecting the periphery of the roller 14. Cooperating with the upper bar 33 we refer to provide the lower bar 37, which is opposite to the bar 33, -with fingers 38 which have a function similar to that of the fingers 29, that is, they guide the blank on its under side, the forward extensions of the fingers 38 terminating between the glue applying faces of the roller 15, and their rear extensions'being dis osed in alinement with and terminating a' jacent to the glue applying faces of the rear roller 14. This lower bar 37 constitutes means for en tirely supporting the fingers 38 between the rollers 14 and 15. One .ofthe advantages of supporting these guides entirely between the rollers 14 and 15 'is that they can be made of'a'm'o're substantial construction and they canbe more readily removed. Also they can be more readily ad'apted'to the desired As it maybe necessary to change or adjust the -guidefingers 36, we-prefer to secure the bar 34 so that it can be readily removed; for this purpose, We prefer to provide slots 34" in the ends of thisbar to receive bolts having wing nuts 34. By loosening the win nuts 34", the bar 34 can be readily removed l particular point.

The fingers 36 are preferably sli htly rounded. at their forward edges, and it will be observed also, that the space between the fingers 36 and the fingers 5-38 preferably con tracts slightly toward the rear.

Behind the rear roller 14 we provide another guiding means for taking the blank ed the roller 14 in order to direct it onto a conveyer, which conveyor is preferably in the form of endless belts 39 passing over rollers l0 and-i1 which support the belts in aninclined position. The belts 39 are preferably disposed intermediate of horizontal belts 42 which pass around the roller ll, and which receive the blank from the conveyer 39..

The guiding means for guiding the glued blank up onto the conveyor 39 will now be.

described. This guiding means preferably comprises a cross bar 43 behind the roller is and near the upper portion thereof, and this bar is preferably provided with a plurality of fingers it which proiectsubstantially horizontally into the space between the glue applying faces of the roller. lhese lingers are preferably formed integral with upwardly curved armsdli, and. they terminate over the roller 141-. Hence they are supported entirely from the rear and do not interfere with the guides that are between rollers i land 15. The fingers l iaet as strippers to take the blank oil the roller, and the forward edge of the blank is then bent upardl by the curved arms' ifi so as to turn over it blank and. deposit it upon the conveyer inverted position, that is with the ed side uppermost. The course of the blank passing over the rollers 1s 1n- 'lQfltStli the dotted line 4-6.

The feed rollers 25 and 2-5 are preferably driven in opposite directions and at the speed by means of gear wheels 17 and 48 which are rigid on these rollers. The gear 28 which is carried by the roller 26 is driven by an idle gear 4-9 from the aforesaid gear wheel '19, see- Fig. 1.

The rollers 41 are preferably supported on a suitable bracket 50 on the side frames 14*.

The feed mechanism and the arrangement for operating the same will now be described. This mechanism preferably comprises a feed table 51 which may be mounted on the forward face of the tank, as shown in Fig; 4: and this feed table has a slot 52 for guiding and clamping a guide bracket This guide bracket carries an adjusting bolt 54 for clamping it in any desired position so that it can assist in holding in place a pack orsupply of blanks 55. The feed table 51 is preferably formed with a bracket 56 which supports a vertical feed screw 57, and on this feed screw is a threaded nut 58 which is formed as a rigid lug on a vertically movable feed shelf 59. This feed shelf supports the blanks in a horizontal position and reciprocates them,

and is provided with a slot 60 through WlllCh the upper portion of the guide 53 extends.

of the ratchet at certain times to prevent the rotation of the feed roller. The feed rollers have rubbing faces of rubber or similar materialadapted to frictionally engage the uppermost blank. In order to recipro cate the feed bar 65, which carries the rollers we prefer to provide a pair of disk cranks 69 which are connected by' connecting rods T0 with arms 71 which are rigid Withthe feed bar 63.. llhe arms 64: project inwardly so that when tension is being exerted in the rods a slight amount of pressure is developed forcing the feed rollersdown on the uppermost blanks. In addition to this, the pull on the rods, of course, produces a movement of the feed bar toward the rollers 25 and 26. l hen the tent 67 is out of engagement with the teeth of the ratchet wheels 66, of course, these ratchet wheels rotate freely and do not vance a blank, but we provide an arrange ment such that on each rearward movem it, that is on each movement toward the feed rollers 25 and 26, the rotation of the rollers will cease at a certain point so that they will then grip the uppermost blank and advance it, for this purpose, we provide a fixed feed shelf 72, see 2, and this feed shelf has two parallel channels or gutters l8 which lie directly under the detents on the .of each detent engages its corresponding ratchet wheel and stops the rotation of the roller. In this Way, the detent performs the function of stopping the rotation-of the feed rollers at a predetermined distance from the rearward edge of the uppermost blank.

In the operation of the feed rollers, the uppermost blanks have a tendency to arrange themselves in a more or less overlapping condition at their rear edges, and in order to increase the friction resistance on their under sides so that the uppermost blank only will be fed forward, we prefer to provide the upper face of the feed shelf 72 with pads 76 of rubber or similar mate rial. These pads assist in preventing the forblanks 55 until the arms 71 come against adjustable stops 79 mounted on the slide blocks 62; as soon as the arms 71 come against these stops, the blocks slide outwardly in'the guideways 6 Any suitable arrangement is provided for 'auton'iatically feeding the blanks 55 upwardly so as to maintain a substantially uniform level for the uppermost blank; for this purpose, the aforesaid feed screw 57 may be actuated by means of a ratchet wheel 80 rigid with the feed screw and adapted to be operated by a spring pressed pawl 81 carmod on a loose arm 82 on: the feed screw. This arm 82 is rocked backward and forward at each rotation of the distributing roller 22 by means of a cam 83 which rotates with the roller andwhioh actuates a rocking lever 84;, said rockin lever 84 being connected by a suitable link 85 with the aforesaid arm 82. From this arrangement, it will be seen that at each rotation of the roller 22 the feed screw 67 will have a slight rotation operating to raise the nut 58 carrying with 1t the feed shelf-59.

Any suitable arrangement is provided for regulating the amount of feed movement, so that if itbetomes too great it will desist temporarily, For .this purpose, we prefer to provide an arrangement for throwing the pawl 81 out of operation automatically. This is preferably accomplished by means of a-guard fin 86 which is formed on a gagement 7 It is understood that the embodiment of the invention described above is only one loose arm 87 mounted on the lower extremity of the feed screw. This arm is connected by a link 88 and a bell crank lever 89 with ashoe 90 pivotally carried on the horizontal arm 91 of the bell crank lever, and this shoe rests on the uppermost blank. If the pile of blanks are fed up too high, the shoe 90 Will raise the arm 91, and this rotates the trip arm 87 toward the pawl and moves the guard 86 under the pawl so as to prevent its engagement with the ratchet wheel 80, or else, limit the amount of its effective enwith the ratchet.

of the embodiments, or forms that the invention make take, and we do not wish to be limited in the practice of the invention, nor in our claims to the particular embodiment set forth.
