Specification of Letters Patent.

Application filed July 8, 1920. Serial No. 394,694.

T 0 all whom, it may concern Be it known that I. PHILIP ZALKiND, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented an Improvement in Glue Rolls, of which the following is a specification. I

This invention relates to an improvement in glue rolls and more particularly to glue rolls employed in conjunction with boxing machines designed to fold and seal paper boxes, cartons and various forms of receptacles. As ordinarily made and sealed it is necessary, in acquiring access to the contents of the form of paper box generally used for cereals and other similar merchandise for example, to disrupt the box in at least some portion thereof, and in the formation of which the ordinary type of glue roller answers the purpose of applying the adhesive in the sealing of the box or package. Heretofore, however, various means have been suggested in the use of paper boxes and other forms of receptacles for making an opening in a predetermined portion of a box or receptacle for removing the contents thereof. In some of these forms of providing the opening in the box or receptacle predetermined portions of the body of the box, and in some instances also predetermined portions of the covers or flaps forming the covers, are designed to assume a normal position and con" dition in the box or receptacle and to be separated along predetermined lines to form a tongue which may be removed partially from the flaps and partially from the body of the receptacle to form an opening to gain access to the contents of'the box and to be closed and maintained in position so that portions of the contents of the box or receptacle may be removed from time to time and the remaining portion of the contents kept in the box or receptacle under substantially the same conditions as regards the atmosphere and otherwise as when originally packed. Difficulty, however. has been experienced with this form of box or receptacle in sealing the same with the usual type of folding and sealing apparatus because of the necessity of omitting the glue or other adhesive at predetermined portions of the flaps which form parts of the tongue that is severed from the body of the box to form the opening therein, and my present invention relates to a form of glue roll adapted. to overcome this difficulty.

) In carrying out the invention the ordinary form of glue roll may be employed and associated in the usual manner with the glue pot or other vessel holding the adhesive and from which to the surface of the glue roll the adhesive may be supplied in any usual or desired manner. In the surface of the glue roll, I provide an opening in which there is a movable member or plunger, the outer surface of which is preferably made to conform with the surface of the roller and is nor mally in registry therewith so that the roller surface is continuous, this being the case when the adhesive is applied to the surface of the roller. I also employ means operative at predetermined times in the revolution of the roller for shifting the plunger for instance for withdrawing the movable member or plunger into the roll so that when this portion of the roll is applied to the flap or cover or other portion of a box no adhesive will be applied thereto, whereby, as will be understood, by suitably shaping the opening or openings in the roll and utilizing the same in the proper positions and in the required number the adhesive maybe omitted from those portions of the box or receptacle in Sealing the same in which no adhesive is necessary so that the tongue portion of the receptacle employed for making the aperturetherein in all parts of the same may be free for use when the opening is to be made therein. 7

In the drawing:

Fig. 1 is a transverse section illustrating a glue roll embodying my invention. i

Fig. 2 is a similar view showing the parts in the opposite position.

Fig. 3 is a plan view of a glue roll in which my improvement is embodied, and

modified form of the invention as is included in Fig. 3.

Referring to the drawing, the glue roll is indicated at 10 and preferably comprises a hollow cylindrical member made of metal or any other suitable material. As illustrated in Fig. 3, the glue roll at the ends thereof is provided with collars 11 and 12 by which the glue roll is mounted on a shaft 13, preferably a stationary shaft. while at least one of the collars that is indicated at 11 is fitted with a sprocket 14 connected by a drive chain or otherwise to a suitable source of power by which the glue roll is made to revolve, it beciated with a glue pot or other adhesive receptacle in such a mannertha-t the adhesive is applied to the surface of the glue roll in the turning of the roll.

In a suitable position in the glue roll, I provide the same with an opening 15. In thi's opeIiing there is fitted a plunger The plunger 16 is citl1ei" coiine'cted to or made integral with a ring member which may be made in parts, vone part of which is indicated at 17 and the other part at 18. The inner surface of the ring member 18 is provided with a cam face l9. while the remainder of 'this inn'er surface of the ring member 18 is circular as is'also the entire inner surface 20 of the ring member 17. These parts of the ring member may be connected by suitable bolts QQpasse'd through flanges on the parts oft-he ring member as indicated atQl. Allso'as illustrated in Figs. 1 and 2, the part 18 of the ring member is provided with a guide pin 23 fitting; into a soc'ketQ't p'rbvided therefor on the inner face of the roll and fitted with a spring 25 which extends between the inner surface of the roll-'and'theadjacent face of the part 18 of the ring memherf in this form of the inventiom'the shaft l3is provided with a projection 26'lving within the ring member and at its extremity fitted with acain roller 27 adapted to contact with thecam' face 19 in order to move the ring'me'mh'er and plunger at predetermined times in'th'e revolution of the glue 'ro'll. As shown in and 2, the part 17 of the ringme nber may be fitted with adjusting screws 28 'mounted in shoulders 29 thereon and'adapt'ed to engage iwith a reinforced portion of the glue roll as indicated at 30= to insure the proper registry between the face of the plunger member and the surface of the glue roll. v V

In the operation of this apparatus as will he understood, the surfaceUof the plunger memlier is normally in that position in which it registers with'the face of theglue roll so that the' same form a continuous surface. This is illustrated in Fig. 2 and in this positioii'the surface of'the glue roll has the glue or other adhesive applied thereto by passing through theglue pot or in" any other manner. In the other position of the glue roll or that shown in Fig. L the eam 'roll e r 27' 'has passed a predetermined"distance along the cam face l9and in doing so, as will be understoodghas withdrawn ring'memher and the plunger predetermined distance into theglue'ioll against'th'e action of :the s'pi'ing'25. '7 This, as will be furthermore understooddeaves a surface' of PIBClBtQI' mined configuration conforming tothe outline of the o ening in 'the glue roll at which noarllliesiv'e will he applied to "the cover or flaps or other-parts off-"a paper box or other receptacle ,in .the operation of applying the adhesiye,:folding-the parts and sealing the same. When the glue roll is turned sufficiently far to permit the cam roller 27 to pass off the face of the cam 19 the spring will force the ring member and the plunger to their normal positions so that the adjusting screws 28 abut against t e reinforced wall 30 and the face of the plunger is again coincident with the surface of the glue roll.

In the form of the invention shown in Fig. 7 4, the glue roll and the plunger are substantially the same as those shown in the other forms of the invention. In this form of the invention I also employ a ring member 31 havinga cam face as well as a projection secured to the fixed shaft and a calm} roller mounted therein to engage with the cam face to move the plunger'into the roller predetermined time.

in the revolution of the gliie roll. The mm face which corre spends to'the cam face'19 is indicated at while the projection "which corresponds to the projection 26' is indicated at 33 and the cam roller 3 1 is the equivalent of'the cam roller 2?. Associated with tl'iis ring 1nein her and either made integral with or connected. thereto and parallel therewith is another ring 'rneinber having .a 'cam face 3 6 which is the'ehinplementof the cam 32, and on the fixed 'shaft lii em )lOYfi cam adapted to cooperate with thec ani face so that in the'revol'utio'n"of.the glue roll the cam 37 is noriiiallv in face '36 to maintain the memh' i s and the plunger in that position iil wlll cli the face of the plunger is'coincident with the surface of'th e glue roll. predetermined position of the glne r011, however, inthe. revolutionthereof, the fa-m137ru'n's off the cani face 86 and simultaneously the c'a1n. 105 rolleril t runs onto the cam face 32, whereby L the plunger and' caiii rings will herlra wn 1" l t KT.
