New York, have invented certain new and useful Improvements in: Envelop-Machines,

of which the following, together with the accompanying drawings, isa specification, the present application being a cohtinuation of my pending application, Serial No. 795,629,'filed October 17 ,1 1913.

The present invention relates to envelop machines, and morepa'rticularly to such machines of the so-called rotary type wherein the va'rious operations in the manufacture of envelope-including theforming of blanks,

andthe gumming and folding of said blanks, are performed in a continuous manner by the passage of the material from end to end in the machine, inrolling contact with the various instrumentalities, thereof.

More particularly, the machine ,of the,

present invention contemplates, initially,'the

' production of blanks substantially arallelogrammic inform from ,a continuously moving web of material, the blanks being cut on the, bias,.or diagonally, fromsaid .web, in

order to economlze' stock and reduce the waste to a minimum. Theblanksthus con,

tinuously severed are thereafter successively subjected to the action of novel and improved gumming and folding devices,.ashereinafter described, for forming them' into completed envelope, and in order to present said blanks in symmetricaldisposition with respect to" said gumming and foldingjdevices, the machine of the present invent-ion includes suitable "mechanism for changing the direction of the blanks-in transit from the original direction ofv the, web,this.. being zilecessitated by the diagonal position of each blank.

' which is-s'evered from the web. 1-

The aboveand other objects "are attained :by the combination and arrangement of blank forming, gummingand folding instrumentalities hereinafter, described] in detall,

The operativeparts of my improved mechanism are represented. in the resent inso stance as mounted on. a suitabletable 1, which .has supporting legs 2, 2: The table 1 supports-a painof longitudinal side frames 3 and 4, and substantially at right angles to the latter a. pair. of transverse side'frames 5 and 6. Power .is imparted to the. mechanism from asuitable source, not shown, by

means of a beltpulley 7 on main driving shaft 8, the latter being suitably journaled in the side frame The shaft v8 carries a pinion 9 whichis in mesh with a gear 10 on a countershaft 11, also journaled in the side 'frame 3. Above the shaft 11 is journaled a shaft 12, which is driven from the shaft 11 by means of intermeshing gears 13 and 14.

,"The gear 1e on shaft 12 serves to actuate the web advancing. and'blank cut-tingdevices of my mechan sm, as hereinafter described.

I The continuous web, as indicated at A,-

Figs. 1,2 and 3, is taken from a-roll A Fig; 2, and is continuously forwarded between the bight of feed rolls and 16 which are carried on shafts 17 and 18 re-,.

spectively having suitable bearings in the frames 3 and 4. Said shafts carry intermeshing gears19 and 20, the firstnamed gear being'also in mesh with the gear14 on shaft 12, whereby the feed rolls 15 and 16 are rotated in unlson, continuously, to move.

,theweb A forward. In advance of said feed rolls are provided cutting cylinders 21 and 22, which are carried on shafts 23.and 24 respectively having suitable bearings in the side frames 3 and 4. .Saidshafts carry intermeshing gears 25 and 26, the first named gear being in mesh with the gear 14 on shaft 12, whereby the cutting cylinders 21 and 22 are driven in the same directlon, relatlvely,

. as the forward rolls'15 and'16.

'The' cutting cylinder 22,, in the present instance, is constructed as represented n Fig. 4. Said cylinder carries at each end. thereofa pair of cutters27, 27', for making the notches 28in the edge of the traveling.

web A, as shown-in Fig. 15; Said cylinder 22 also carries a centrally disposed cutter 29, for making at each revolution a center cut 30 in the webg'as shown in Fig. 15. The cutters 27 and,@9 of cylinder 22 cooperate with the surface of cyl1nder 21 in making the four edge cuts.28 and the sin le center cut 30 in.

the webat each revolution, the surface of' cylinder 21 beingpreferably hardened for-- this purpose. The pieces or chips of the web A which are defined by these cutting operatime may not become entirely se rated from the web on account of. the-fact that some ofthe fibers of the material remain unf severed, and it may benecess'aryto em loy a mechanism for removing. thesepartlally separated chips from the traveling web,

Such a chip removing mechanism-may take any suitable form,-suchj as that shown in my copending application Serial No. 798,236, filed October 30, 1913. The details of such mechanism constitute no part of thepresent ing thereof is unnecessary.

In advance of the cylinders 21 and 22, the

invention, and hence a description or showmachine herein'shown provides cutting cyl; I inders 40 and 41, which are carried on shafts- 42 and 43 respectively, having intermeshs5 ing gears 44 and 45. The latter of said gears is in r-mesh with an intermediate" ear 46 that -is driven from the gear 25 of t' 21. One of said cutting cylinders, .here shownas the cylinder 41, Figs. 5 and. 6, provides a substantiallyhelical cuttiiig blade 47,

which-is secured thereto ina-ny suitable-mam- 1161188 bymeans of a retaining screw 48 ene5 1 eo nmncementgof-this movement, one of said 180 sever the travelin web A- on successive oblique lines 50, Fig. 15, whereby to form blanks which are substantially parallelogrammic in outline. The cutting cylinders 40 and 41 are rotated in the same relative directions as the cutting cylinders 21 and 22, by the gearing as above described, and the speeds of all said cutting devices are so timed that the lines of out 50 will intersect the opposite corners of center cut 30 as'well asthe apexes of those notches 28' which are directly in line with each center cut 30, as clearly shown inFig; 13. Instead of sepa' rate pairs of cutting cylinders 21, 22 and 40, 41 respectively, the functions above 'described may obviously be performed by a single-pair of cylinders, the cutter carrying member of which would have the blade47 in additionto the cutters 27 and 29.-

Inadvance of the cuttin devices as here-' invention provides cylinders 52 and 53 for forwarding the separated blanks inthe line of travel of web A, each blank being received into the bight "of said rolls, 52 and 53 in an oblique osition. That is, the oblique line 50 'constiutes' the advancing edge of successive blanks in each instance, said. edge being formed by contiguous portions of one of the longitudinal flaps and one ofthe side flaps of the. blank, as shown clearl in-Fig.

15. With the blanks traveling in t is direction, with such an obliqueedge foremost,

there is 'no way in which the same'maybe centered and squared for the subsequent such "a change in the direction of movement of the blanks as willpermit of their advancement in a symmetrical relation to the machine as regards their projecting side, back and seal flaps, and at thesame time re described, with a minimum waste of stock. 'To'this end the cylinders 52 and53- are rotated'so as to advance the separated blanks continuously through the machine, saidcylinders being carried on shafts 54 and 55 respect'vely which have intermeshing gears 56 and 57. The formerof said gears is in gummingland folding operations of the ma- -chine,and the present machine contemplates Twining theadvantages incident tocutting t and forming the blanks in the manner-above mesh with an intermediategear 58 that is I driven from the gear 44 of cutting cylinder 40, whereby the cylinders 52 and 53 are-rotated in unison, in the same direction. relatively as the previously d cribed forwarde cylinder ping, cutting and chip remo 'ng cylinders to ,move the blanks .in substantiall the same direction 'as the web A. The requisite change in directiomi'or partial, rotation of the separated blanks, -"-is' effected by .devices in advanceof, thec linders 52 and '53, as hereinafter describe and for thepurpos'e' releasinggeach ,fjjllSl'i ;;prior"to the advancing edge of said blank is seized thereby, as hereinafter described. It is to understood,-however, that my invention is not confinedto the, particular means. herein shown and described for releasingthe blank from' the bight of forwarding rolls; 52- and 53, namel the segmental cutaway portion 59,-it be1ng clear that-any eq uivalent releasing means, such as a mechanism for momentarily separating said rolls at the proper period in their revolution, could as well be employed.

The direction changing devices for operation on the separated blanks consist in the present instance of coacting frusto- conical rolls 60, 61, arranged with converging axes at an angle oblique-to the'parallel axes of the previously described blank advancing cylinders .52-and 53L Said rolls" and 61 are carried on shafts 62 and 63 respectively, which are journaled in ' suitable brackets 64 and 65 supported on table 1. The shafts 62 and 63 carry intermeshinggea'rs' 66 and 67,

which are slightly beveled to, compensate for the convergence of said shafts. The

, shaft 62 of lower roll 60 carries a bevel gear 68 which is in mesh with a beveli gear 69. on

V a transverse shaft 70, the latterbeln 'driven by bevel pinions 71 and 72 froma-s aft 7.3.

The latter'is rotated in synchronism-With the blank. cutting and advancing devices of 4 the machine by abevel gear-connection 74,

75 with the main driving shaft 8. h

The separated blanks as received in the bi'ght of conical rolls 60, 61" have theirfldirection of advancement varied, by reason of the greater peripheral speed of the larger ends of said rolls, as will be understood.

The blanks are swung gradually through the path indicated by the broken lines B, B,-

. Fig. 15,- their motion of translation being continued during their rotation, so that they finally assume the positionindicated at C, Fig. l'5,-in which the projecting side andlongitudinal flaps are symmetrically dis posed about the rectangular portion which defines the shape of the completed envelop or inclos-ure. V In this position their advance is adapted to bewcontinued, in a straight- .v

line, by means ofcoacting cylinders 76 and 77, Fig. 8, which are journaled =in the' side I framesjf) and 6 with their'axes at right anseizing the advancing edge of the blank unglesto the axes of cylinders 52gand 53. The cylinders 76 and 77 are substantially the counterparts ofwcylinder- s 52 and 53, in that one of the former, in the present instance cylinder 77 has a segmental cutaway portionJ 8, which prevents said cylinders from they may be placed inclose proximity to the for accomplishing this same result could be employed. The cylinders 76- and'77 cooperate in advancing the blank to the blank 70 centering, squaring,-gi1mming and'folding devices of the machine, as hereinafter-described. Said cylinders'76-and 77 are ro tated by suitable intermeshing gears 79 and 80, one of .which, 79, is shown in Fig. .7 as beingdriven from a gear 81 onshaft 82,, the latter having a bevel gear connection 83 with shaft 70. i For facilitatingthe' blank turning action of the conical rolls :60, 61, I provide coacting pairs of short cylindrical rolls 81, 85 and 86, 87 which are located respectively onops posite sides of said conical .rolls,between the same and the adjacent pairs of cylinders 52, 53 and 76, 77 respectively. Said rolls 84 85 and 85 are carried on shafts 88 and 89 respectively, having intermeshing gears 90 and 91. The former of said gears is driven by an intermediategear 92 which is in mesh with gear 56 of cylinder 52, whereby the rolls 84 and 85 are rotated continuously in the same relative directions as cylinders52 and 53. Said rolls 84, 85 are considerably shorter thanthe cylinders '52, '53, whereby ,7 95 conical-rolls 60, .61, in order to insure the feeding of the edge of each separatedblank 'to thebight of said conical rolls near-the outer larger ends of the latter; y One of'the rolls 84, 85', in the presentinstance the upper ,roll 85, has a segmental cutaway portion 93 similar to the portion 59 of cylinder 53,

whereby the release, of a, blank is effected .When the latteris seized bythe conical rolls 60,61. The rolls 86, 87fare;substantially counterparts of the rolls. 8 l, 85, one of them, inthe "present instance the roll 87,having a segmental cutaway portion Qtwhich prevents said rolls from seizing the blank until thelatter has been released by the conical rolls (SOandY 61, Said rolls 86, 87 are driyeu by inter-meshing gears 95, 96 respectively, Fig. 7 one of which is in mesh Withan idler 96' that isjdrivcn froun gear 79 of roll 76. One of the conical rolls, in the present instance roll 61, has a segmental cutaway portion 97, whichbecomes operative to release the blank-from the bightgbf said rolls at the end of their turning operation thereon, just described mechanism, the separated blanks are each in turn moved cont inuously into the conical rolls 60, 61, andthe final rolls 8%, 85

operate tosiving/the, outer end or edge of the 1% blank while remaining inoperative with respect to itsinncrcnd or edge. The latter partakes of the gradual movement of'trans .lation {which is accomplished by the smaller in'nerends'of conicalrolls66, 61, and'is not away portion97 releases the blank from said conical rolls just assaid blank is seized by operated upon by the rolls 86, 87 which act only on the more rapidly moving outer end or edge. The segmental cutaway portion 93 releases the blank from the bight of rolls 84, 85 just as the blank is seized in the bight of conical rolls 60, 61, and the segmental cutrolls 86 87. The latter complete the Wide swing-ing movement of the outer of the blank, and therafter the forward edge is seized in the bight of rolls 76, 77 and the blank is advanced into the position C for the l I operations of centering, squaring,

gumming and folding, as hereinafter described.

It will be seen that the successive blanks, asf'cut obliquely from the web A, have their speed of advancement in the direction. of said web gradually reduced as" they come into'the bight of conical rolls 60, ,61. Simultaneous with their reduction in speed in the direction of web 'A, there-.is-a combined movementof translation and rotation by said. conical rolls and by the short rolls adapted to receive, 'on the under surface of one construction the roll 86 84, 85 and 86, 87 which carries the blanks through a curved path, whereby they come into symmetrical relation to the direction of.

advance of the forwarding rolls 76, 77.

As the blanks are successively turned into the position C, wherein they are symmetrically disposed for the further operations of gumming and foldin thereon, they are of as indicatedf'at 98, Fig. 15. In the present is adapted to perform this function, shorter than its coacting roll 87, as shown in Fig. 9, and carrying quired relative position for making contact with the tip ofthe side flap of each blank passing thereabove.- The arm 99 makes con tact at anotherpart of its revolution with 45 the periphery f a gum transfer roll 100, which isrevolubly mounted and partially submerged in a gum box 101-, being drivenfrom the shaft of idle gear 96 The'above described'gumming operation is useful in insuring theadhesion ofthe two side or end flaps of the. blank, when the latter are folded. over'into contact, as shown at 102,

The upper'courses of'these belts'serv f -convey ngvmeans for end or edge if deslred, a spot of gum d the side flaps,

said roll being made.

I on its shaft a gnmming arm 99, of the proper size and in the rewords, alinement, the-pin 124 'first engaged by its the successively received blanks, and the belts are operated at a speed which acceler-" ates the movement of the blanks over the speed imparted thereto by the rolls 76 and gear 117 is driven from gear 81 by means of an idler 119.

While on the belts 108, each blank is adapted tohave its side flaps folded inwardly, and on account of the necessity for bringing each blank to a momentary rest for this purpose, the belts are timed to increase the speed ofeach blank, as heretofore de scribed. The blanks are held in firm frictional engagement with the upper courses of belts 108.by means of gravity resting balls '120, Fig. 8,'which are loosely carried in rearwardly projecting portions of a cross member 121, supported by the frames 5 and 6 above the plane of advance of the blanks. At its rear portion said member 121' carries guides 122, which prevent the 121 supports a stationary forming plate 123, which is spaced slightly above the u per courses of belts 108-to permit the bla s and said belts. p

A pair of fixed registering pins 124, 124 are suitably. mounted on, inwardly extend.-

ing brackets 125, so, as to"'project in the path of the Hat blanks: at the-forward corners of forming plate 123, Fig. 1 These register: ing pins are adapted. to interrupt the movement of a, blank by the belts-108, and at the same-time to cooperate with the advancing edge of said blank to center and square the prellminary to the side fiap folding' operation, by their engagement with the resame entrant angles 28, 30 of said edge. In other if a blankion the belts 108 is out of isplacement of the blanks from the belts 108. At its forward portion, the member to enter edgewise between said forming plate V leading edge will act as a pivot until the blank pin, due tothe constant-frictional contact of the blank with the.v traveling belts 108. This movement of belts1081will also cause the advancing edge-of the blank to slidealong the pins/124 until said pins reach the reentrant angles 28, 30, thus bringing the blank into' registeredposition beneath the forming plate 123. The lateral edges of. said forming'plate lie inwardly slightlyof the pins 124 and said is broughtup square with theother edges constitute the folding edges for the projecting side flaps of the blank. After the centering and squarin above described, said pro ecting side flaps of. the blank as which are disposed in the positions indicated att'126, 126, Figs. 1 and 11, are acted upon by reciprocating folder plates 127, 127,

which are carried o l-supporting members force .the side flaps 126 upwardly and inwardly over the lateral edges of forming plate 123,as shown in Figs. 11 and 15.

Thereafter, upon the simultaneous retraction of folding plates 127, the blank is freeto be moved forwardly by the belts 108-since the advancing edge of said blank is entirely between the pins 124.

As herein shown the belts 108 and disks 113 deliver the blanks, with their side flapsthus folded, to the bight of printing cylin: ders 132, 133, of which the formerm'ay be a type cylinder and the latter an impression cylinder. Said cylinders 132 and 133 are carried on shafts 134.and 135"respectively,' having intermeshing gears 136 and 137, the former being. driven by anidler 138 from the gear 115 of shaft 110. Ink may be supplied to cylinder 132 through the usual rolls 139. and 140, spreader 141, andthe usual transfer vibrating ductor and fountain devices indicated as a whole by the numeral 142, Fig. 7. It will be understood that the use of .the above described or any other printing mechanism, for impressing an ,address or the like on the under surface of the blank is entirely optional and, if desired, such mechanismmay be dispensed with, and; the blanks delivered instead directly to the seal and back flap gumming and creasing mech anisms, which, will now be described.

Feed rolls 143 and 144 are adapted to seize the blanks as they leave the belts 10801 the printing mechanism, as the case may be, and advance the same successively for} further operations thereon. Said feed rolls are carried on shafts 145 and 146 respectively hav-' ing intermeshing gears 147 and148, thelatter beingdriven through an idler 149 from the gear- 1370f the printing mechanism. In advance of said feed rolls are disposed shafts 150 and 151 having intermeshing gears 152 and-153, the former'of which is driven through an idler154 from the gear 147 of feed rollshaft145. Theshaft 151 carries a segmental gumming member 155, which supports a back flap creasing blade 156 and a seal -flap creasing blade-1157',

- These blades cooperate, in the ordernamed,

with grooves 158 and 159 respectively in the surface of a. roll 160 on shaft 150, to crease the blank as it passes betweenmember 155 and roll 160, on the lines 161 and; 162 re s'pec'tively, Fig. 15. 'By the cooperative action of'blade 1 56 withgroove 158, the advancing. or back flap of the blank is deflected upwardly, as shown. at 163, Fig.8, and the same is true of the rear or seal flap of theblank whenithe blade 157 and groove 159 become operative with respect thereto.

The member 155, in addition tothe creasing functionsabove described, is operative as a gumming device, to apply the strips of gum 164, 164,,Fig. 15, to the side flaps in readiness for the folding over thereon of the creased seal flap 163. .To this end the surface of member 155, between the blades 156 and 157, is adapted to receive a suitably disposed line of gum alternately from gumming ledges 165', 165, which are carried 'by rotating arms 166, 166. Said arms are mounted on a shaft 167 which has a gear 168 in mesh with the gear 153 of shaft 151. The

gumming ledges 165 are adapted to make contact in their rotation with a gum roll 169 which rotates in a suitable gum box 170. The arms 166 also carry suitably shaped gumming- ledges 171, 171,supp'lied from the roll 169 and adapted alternately to lay a line of gum on the surface of memher 155- behind the blade 157, whereby to gum the seal flap, as shown at 172.,v Fig, 15.

In advance of the mming and creasing devices above describ .d, the blank is projected onto a supporting guide 173 which is carried on a transverse stationary rod 174. A stationary guiding-rod '175 is so spaced above the guide 173 as to engage the upwardly deflected back flap 163 of the blank, and by. the continued advancement of said blank to fold orturn-said flap into theposition indicated by thebroken line 163, Fig. 8. .Thereafter said back flap is completely folded 'down, and'pressed into contactwit the gum 164, :by the passage of the blank between-pressing rolls 176 and 177, the latter of which has a cutaway portion 17 8, to prevent interference-with the um 172 on. the

'seal flap. The shafts of said rolls have intermeshing gears179and1180, the former of whichis driventhrough an idler 181 from the gear 152. of shaft 150. J

x The envelop is thus completed save for the turning down of the seal flap, which'has already been partially creasediby the action of blade 157 and groove .159. The 'sealfiap :folding mechanism comtp'rises stationary ides 182 and 183, inthe orm of transverse are above and below the plane of advance .of the envelop, and just inv advance of the pressure rolls 17 G'and 17 7 Beyondsaidbars 182 an-d 183 the folded bottom edge of the envelop" encounters upwardly inclined defleeting members 184which depend from a transverse rod 185, Said, members 184,

which are preferably two in number and spaced apart, as shown in Fig. 1, have projecting stops 186 thereon with which the advancing bottom edge of .the envelop makes contact, as shown in Fig. 12, before the rear or seal flap has passed out of the bight of pressure rolls 176 and 177. In assuming the position shown in Fig. 12, the envelop is acted-upon by upper rod. 183 which causes the bending of the seal flap along its creased line 162. In the further advance of said h of'the -envelop, the endsof said fingers being notchedas at 189, to insure engagement with. said edge. The descentof said fingers completes the folding of the sealflap, which isthus kept out ofcontactwith the back wall of-the envelop, and simultaneously projects'said completed envelop ,intoth'e spaces of a suitable-dryingchain 190, or "other envelop receiving instrumentality, driven by gearing 191, 192 and 193"from\g'ear-181..

. '.The'shaft 188 is driven by a gear- 194 thereon, which is inturn driven, through gearing 195 and 196, from the gear- 179' of roll 176.- The fingers} 187 operate to. make a. revolution -.for. each envelop arriving fiap:of-each is folded, as above described.: A modification of theseal flap folding devices is lshown in.
