Application filed August 1, 1904. Serial No. 219.100.

1'0 (1,7 7 whom, it may concern;

Be it known that I, GEORGE IV. DIETZ, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Envelop-Making Machines, of which the following is a specification.

One object of my invention is to provide an envelop making machine Whose various parts shall be relatively adjustable to permit of the manufacture of envelops of any desired size and shall at the same time be so ar ranged and constructed that it may be operated at a high rate of speed.

A further object of the invention is to pro vide a machine of the above-noted general character which shall have improved mechanism for operating its paste-cups and their attached mechanism, said mechanism being so arranged that the paste wheel or wheels shall be moved at predetermined times into and out of engagement with the web of paper from which envelops are to be formed as said web is moved through the machine.

It is further desired to provide an envelopmaking machine which while cutting out an envelop-blank from a web of paper also re moves certain portions of the sides of said web, thereby reducing the quantity of paper necessary for an envelop of a given size as Well as securing a valuable by-product from the pieces so cut off.

I also desire to provide an envelop-inaking machine which shall include a device for braking the blank feeding mechanism so that this latter shall be periodically stopped and held at a predetermined point, thereby insuring that the envelop-blank is cut and folded at the proper points.

I further desire to provide a machine having the above elements so constructed and assembled that it shall as a whole be of relatively simple construction and inexpensive as regards the labor and material involved in its production.

These objects, together with other useful results more fully set forth hereafter, I secure as follows, reference being had to the accompanying drawings, in which- Figure 1 is an elevation of one side of my improved envelop-making machine. Fig. 2

is an elevation of the opposite side of the machine. Fig. 3 is a plan view of the structure shown in Figs. 1 and 2. Fig. 4 is a perspective view, on a somewhat enlarged scale, illustrating the detail construction of certain of the dies as well as of the paste-cups, together with the mechanism for operating these parts. Fig. 5 is a perspective view illustrating the detail construction of the cutting-off die and one of the feed devices,together with the mechanism for operating the same, certain portions of the machine being omitted from this figure, as well as from Fig. 4, for the sake of clearness- Fi 6 is a perspective view showing the feed-rollers and the side following devices. Fig. 7 is a perspective view showing the detail construction of a portion of the mechanism for operating the feed-rolls, and also illustrating the brake employed for checking their movement at a predetermined time, it being understood in this figure, as well as in Figs. 4, 5, and 6, certain parts of the machine have been omitted for the sake of clearness. Fig. 8 is a perspective view of the longitudinal scoring devices. Fig. 9 is a perspective view of the adjustable cam for varying the length of time during which the paste wheels or rollers remain in engagement with the web of paper or envelop-blank. Fig. 10 is a side elevation of a portion of the ratchet mechanism shown in Fig. 7. Fig. 11 is a plan view of a portion of the paper web during its passage through the machine, showing the various steps in its formation into envelop-blanks; and Fig. 12 is a front elevation of a finished envelop made by my machine.

In the above drawings, A is the frame of the machine, the main ortion of which is composed of two side pane s a, which in the present instance are illustrated as resting upon a floor, but which may, if desired, be supported in any desired manner upon legs or standards. These panels which, as shown in Fig. 3, are parallel to each other, have projecting from their rear ends two brackets a, formed with bearings for the support of a shaft a carrying the roll or web of paper from which envelops are to be made. This roll is positively driven by a pair of friction-disks a and a, the latter of which is carried on a shaft a continuously driven through a train of gears from the main driving-shaft a, on which is a driving-pulley a, as shown in Fig. 2. The speed of revolution of the roll-carrying shaft a may be varied by moving the friction-disk toward or from the center of the disk 0, by proper manipulation of a nut a on a screw a which has an arm in engagement with a collar a, fixed to the disk (1*. Revolution of the nut therefore moves the screw a longitudinally, and consequently slides the friction disk a on. its shaft a.

From the roll a the web of paper passes over rolls or small shafts l) and 7) and under rolls 6 and l), and thence through mechanism hereafter described to a pair of feed rolls 0 and 0, carried on shafts c" and c, supported in bearii'igs in upwardly-projecting frames or standards C, adjustably held to the side panels of the frame of the machine, as hereinafter set forth.

In order to drive the feed-rolls, i provide a crank d, fixed to a shaft (1, on which is carried one of the train of gears driven from the main shaft a and heretofore referred to as driving the shaft of. This crank is slotted for the reception of one end of a connectingrod D, made in two sections (Z and d, telescoping into one another, as shown in Fig. 1, and connected. at its opposite end to a toothed segment d. The crank end of section (Z may be moved in the slot of said crank toward or from the crank center, and the two sections of the connecting-rod may be moved together or pulled apart to adjust the length of said red by properly loosening the nuts (Z As illustrated in Fig. 7, the teeth of the segment CZ mesh with a pinion e, loosely carried upon the shaft 0 and l'iaving fixed to it an arm 0, provided at its upper end with a pawl 6 shaped to engage the teeth of a ratchet-wheel e, keyed or otherwise fixed to the shaft 0. Fixed to said pawl, so as to be movable upon its pivot, is an arm 6, projecting toward the shaft 6 and having on its inner end a head loosely ongaged by one end of an arm a, movably mounted upon the shaft 0, and yet so fitted that there is considerable friction between it and said shaft.

The two standards C in the present instance consist of plates or frames extending each parallel with one of the side panels (I! of the frame of the machine and sliclably rest-- ing upon the upper edge of said panel, which is faced off to serve as a guideway or slide. In each of the side panels are two elongated slots a and a for the reception of bolts a, screwed into each standard.

On the opposite end of the shaft 0. from that having the ratchet-wheel c is a gear 0*, meshing with a similar gear a on the shaft 0 so as to drive the upper feed-roll c. This roll consists of a number of parallel disks or rolls, as shown in Fig. 6, or it may be de scribed as a roll having a number of annular recesses, whose distance apart depends upon the distance between the two lines along which paste is applied to an envelop-blank. In the present instance there are five sections to this feed-roll, and this latter, as a whole, is pressed toward the lower roll 0 by springs 0 active upon the bearings, in which iscarried the shaft of the roll c. Carried upon portions A of the side panels of the frame A is a die-plate F, having adjacent to each of its longitudinal edges an oscillator; knifej, which has projecting lugs f, fixed to a barf supported in. bearings) Fixed to that endv of each of the shafts nearest to the feed-rolls c and c is an armf, slotted at its outer end for the reception of a blockf", attached to a barf", which projects rearwardly and horizontally therefrom longitudinally of the machine. Said latter bar is f' ad to and extends at right angles from a vertically-movable shaftf reciprocated b means of an eccentricf fixed to the she. 1", which is driven from one of the gear ((lll. necting the main shaft a and the shaft (1, as shown in Fig. 2, there being an occentr1c-rod f connecting said eccentric to the lower end of the shaftf Each of the barsf has upon it two armsf respectively, projecting toward each other and supporting between them a pair of vertical plates 1", having sharp lower edges and serving as transverse scorers for the web of paper.

In line with the edges of the knivesy" and between the rear ends of the same and the rolls 7) l), &c., is a shaft g, carrying a pair of scoring-disks g, each of which has coacting with it a grooved disk 1 carried upon a shaft 9. Both pairs of these disks are fiscal to their respective shafts by set-screws, so as to be adjustable toward and from each other to suit various widths of envelop-blanks Just in front of and. beyond. the die-plate l and the knives f is a shaft ll, carried in bearings in brackets 71/, projecting upwardly from the side panels of the frame, which brackrt also have the bearings f for shaft f and having a pair of paste-cups 7i adjustahl v fixed to it in such manner that as said shaft is oscillated the forwardly-projecting and lower front portions of said cups are raisril. and lowered. From Figs. 3 and d it will be seen that these cups may be moved upon their shaft ll toward andv from each other, and for oscillating said. shaft there is providrd an arm 71?, fixed to it and connected to a downwardly-extending bar 71/ attached by a link 72 to one arm of a l: oll-crank lever 71, loosely mounted uponv the main driving-shaft c. The second arm of this lever carries a roller If, which engages with the periphery of at ea in .l preferably of the construction shown in Figs. 4 and 9. This cam is carried on the shaft f and has movable segments j and j a lju l ably held to its body by means of screw By loosening the screws j and moving the segments and j the times at which the in llcrank lever 7L oscillz'ttcd may be variul. so as to correspondingly vary the times during which the lower ends of the paste-cups are in their normal or lowered. positionthat is. with the past-distrilniting rollers 7r in (ngagement with the web of paper. One of said rollers its projects into the bottom of ICC) ISO

each paste-cup through a suitable slot therein and is supported so that it rests upon the web of paper when the paste-cup h is in its normal position, it being fixed to a shaft h, journaled in the sides of the cup. This shaft has fixed to it a pinion h driven from a shaft is, through pinions 1c and 7: there being a belt 7c extending between pulley-wheels, respectively, on shafts 7c and 0 In Fig. 5 is shown the mechanism for finally cutting off and folding the envelopblanks, this consisting of a stationary knife or die-plate M, extending transversely of the machine and having an oscillatory knife m parallel to and coacting with it. This knife m is carried on a pair of arms m, fixed to a shaft m to which is also attached a down wardly-projecting arm m having fixed to it a bar m Said bar is adjustably engaged with one arm 19 of a lever P, loosely carried on the main shaft a and provided with two other arms p and 19 on the latter of which is a roller p held in engagement with a cam p on the shaft f 9 by means of a spring p Said spring is confined between a bracket 19 proj ecting from the side panel a ofthe frame A, and a nut 19 on a rod 19 attached to the third arm p of said lever. It will be noted from Fig. 5 that with this arrangement of parts the knife m is normally retained in an elevated position, and consequently also maintains elevated a plate g which constitutes part of the final folding mechanism for the envelop-blanks. Said plate is carried on a bar q, slidingly adjustable on two bars (1, adjustably held at one end in the casting extending between the arms m and carrying the knife m. Said plate (1 acts between two rollers (Z3 and g carried in bearings at the upper part of frames or standards Q, adjustably carried by the side panels of the machineframe in a manner similar to that in the case of the plates Cthat is to say, they are held in position by stud -bolts (1 which pass through the slots a and a so as to permit of said plates Q and the mechanism carried by them being moved toward and from the plates C and the mechanism thereon. The roller g is carried in a movable bearing yieldingly pressed toward the roller by means of springs q, said roller being driven by means of a belt 9 passing around pulley-wheels (1 and (1. respectively, on its shaft and on the main driving-shaft a. A gear 1 on the shaft of roller meshes with a second gear Q9 on the shaft of roller q, thereby driving the lat ter. Said belt also passes over a pull eywheel r, fixed to the shaft of a roller 1", there being a second roller 1, resting upon said first roller and so placed that the line of contact of the two rollers is in the plane of the web of paper passing through feed-rolls c and c and over rolls (1 and (1 Betweenthe feed-rolls and the paste-cups h and adjacent to said rolls is a cross-bar T,

carried upon the two plates C and having adjustably depending from it two curved pieces 25, which together form a folding throat for turning inwardly the edges of flaps of an envelop-blank prior to its passage through the rolls 0 and 0. These two pieces have guideplates t, projecting toward the paste-cup and are provided with set-screws, so that they may after being adjusted toward or from each other be held in any desired position upon the cross-bar T.

In order that the feed-rolls may be instantly stopped from turning as soon as the driving means therefor ceases to act, 1 provide a brake of the construction shown in Fig. 7. Said brake includes a bar V, extending between the side frame panels and having pivoted to it a shoe 1), whose free end is connected to one arm of a lever 12 by means of a link v Said lever is loosely carried upon the shaft a and is provided with a roller 12", coacting with a cam 11 upon the shaft f Said cam is so adjusted on the shaft that at predetermined times it turns the lever v and forcibly draws the shoe "0 against the roller 0, thereby preventing further rotation of the roll for the time being.

Under operating conditions the roll a upon which is carried the web of paper, is continuously rotated from the driving-shaft a, so that said web is delivered therefrom and falls in a loop between said roll and the roll b. Since by means of the crank (Z, connesting-rod D and segment d", the pinion e is alternately revolved in opposite directions, it will be seen that the pawl c is alternately engaged with and disengaged from the ratehet-wheel 6 thereby intermittently turning the two feed-rolls e and 0 By means of the device shown in Fig. 7 the pawl is raised from engagement with the teeth of said ratchet-wheel as soon as the pinion e, and with it the arm 6, start to move backward, since the arm 6, and with it the pawl, is caused to turn on its pivot by means of the piece 6 immediately upon reversal of the direction of movement of the arm c. Similarly when the movement of the pinion is again reversed said piece a by reason of its frictional bearing on the shaft 0 again turns the arm e and the pawl on their pivot, and so throws said pawl into engagement with the ratchet-teeth. It will thus be seen that while the paper is fed from its supply-roll continuously it is intermittently taken up by the machine.

During the time that the feed-rolls c and c are inactive the eccentric f on shaft f causes the bar f to be moved downwardly, thus bringing the two bars bodily nearer to the die-plate and causing the blocks on said bars to slide in the slots of the arms f, so as to oscillate the shafts f 2 in their bearings and cause the knives to move downwardly past the shearing edges of the die-plate F.

There is thus cut in each side of the web of paper an elongated recess, as indicated at in Fig. 11, it being noted that previous to such action the scoring-wheels g and g make longitndinal scores in the web in the line of cut of said knives. The bodily downward movement of the bars f brin s the transverse scoring-platesf into engagement with the web of paper along the lines indicated at a) and 0: and after this operation knives and score-plates are raised and the teed-rolls c and 0 move the web forward, through the length of one envelop-blank, (indicated in Fig. 11. at ev The cam J on the shaftf is so set that as the Web is moved under the front lower p o rtions of the paste-oups the rollers its for feeding the paste from said cups are permitted to rest upon the portions of said web (indicated at at) until said web has been moved. so that the transverse score-line comes adjacent to the line of contact of said rollers with the web. Vi hen this point is reached, said cam acts and oscillates the paste-cups on their shaft H so as to lift the rollers ont of engagement with the web. The next op eration of the feed-rolls causes the projecting flaps to be engaged by the folding throat formed by the curved pieces t, and inasmuch as the web has been. scored by wheels 9 along the lines at its passage thrr h the feed-rolls causes the turned-in flaps to remain in their folded positions. After passage through said feed-rolls c and c the end or the web rests in the machine so that the portion indicated by the line 1: is directly over the shearing edge of the stationary knife M while the scored line at" is directly over the line of contact of the two rollers and q and under the edge of the folding-plate The cam p is therefore so placed on the shaft/' that as soon as the feed-rolls have brought the end of the web to the position above noted and have been stopped by the application of the brakeshoe 1) under the action of the cam 'v the knife or, and with it the folding-plate q, are moved downwardly, the former cutting oil the end of the web {T0111 the body tl'iereo'l and the latter starting a double thickness of said web down between the rolls (1 and q", whereby the portions 23 of said end, to which adhesive material has been applied, are pressed against the outer faces of the inwardlyturned ilaps 111 thereby completing the envelop, which is delivered into any suitable receptacle or conveyer, which, however, is not shown, as it forms no part oi the present invention.

The upper feed-roll c is made in a number of sections, as shown, in order that the portions or" the paper web to which adhesive material has been applied may pass said roll without sticking thereto or without depositl ing any oi the adhesive material thereon. lit will be seen that 11' 1t be desired to manufacl l i came? ture envelops 01' greater width than those For which the machine is set in the drawings the various disks or sections of the teed-roll may he moved. upon their supporting-shai't, so as to bring the spaces between sections (1 and r in line with the line ol paste deposited by the paste-wheels It operating in the paste-cu ps The paste-cups are also movable uponv their supporting-shait toward and from each other, and similarly the gear-wheels 7c are also mov able upon their shaft 7; to permit of this ad- 'ustment of said paste-cups. in order that the greater width of web may be accommodated and cut to the proper dimensions, the die-plate ii and the knives f coacting therewith. maybe removed and replaced by others oi the desired width, the score-wheel gand g being ad insted upon theirsupporting-shal'ts -g and g in order to form the longitudinal scoring-linesin the desired positions on t he envelop-blank.

When it desired to produce a longer envelop than would be formed with the various pa: s ol the machine adjusted, as shown in the drawings, 1 vary the length ol the con necting-rod l) by slacking oil the nuts d" and pulling apart its telescoping sections (I and d, also corres )ondingly varying the. throw of the crank d. Such adjustment causes the length or web drawn out by one operation ol" the teed-rolls e and (1 to be increased, it being also iiecessary to move the plates U and (,1; farther away 'l rom the part of the machine carrying the paste-cups, &c., as well as larther away i'rom each. other. The loldiugplate (f will also rei' uire to be correspoudingly moved upon the bars r it being understood that the various connectiug-belts will have to be lengthened accordingly.

in order that the paste-cups may deposit adhesive mater al uponv the web tor a greater distance than originally, it will be necessary to slack oil the screws fol" cam J and so ad inst the segments j and j that the active portions thereof will not oiiierate the bell-crank lever /'i so as to raise the rod 72/, and consequently the pastewiip and its ieeding-roller, until a later point in. the cycle of operations or the machine.

From the above it will be noted that the various parts oi the machine may l easily and quickly adjusted, so that it is possible to make envelops of any desired size within very wide limits, and it \\ill be further noted that owing to the particular type ol envelop which it designed to mztnulacture i am enabled to recover the long pieces of paper web cut oil' from the sides thereof, where otherwise the same parts have been required in the making oi the envelop. Such scrap-paper is ol very appreciz'ible value, and its saving coiisi itutes one oi the valuable l' nitures oi the machine. I
