ENVELOP-MACHINE.

I Application filed June 3,

signed for making that type of envelop or folded continuous strip required in the op eration of vending machines, more particularly that type ofvending machiiie disclosed 111 my co-pending application filed March M11908, Serial No; 421,133, and especially designed for making the sales strip that forms the subject matter of an allowed application for patent filed by James R. Williams, Feb. 12, 1907 No. 357,039 allowed Jan. 14,1908. 1 i I 'lhatthe operation and the purposes for which my present invention is designed will be the more readily understood, it should he her-e stated, that-the machine disclosed in my co-pending application before mentioned, ismore particularly designed for selling postage stamps and for delivering each sale of stamps inclosed within an en.- vclop, the envelop being in the nature of a section of the continuous sales strip, specitically descrihcd and illustrated in the allowed \Villianis application before mentioned, and which is also disclosed in the presentcase. v

Briefly stated, in the practical applicationof a continuous envelop or salesstrip produced by my invention, the sales strip or envelop is composed ofa lone; rih- I hon' of paper vfolded in the direction of length upon itself. and at equispaccd dis tanccs the lapped folds are gunnned or otherwse secured to form a series of pockets, in each of which is held the stamp or st amps that constitute the single sales, and which, when the proper coin isinserted into the machine and the same is operated, are severed, one section at the time, and with the contents, are discharged from the machine.

tions of the strip or envelop is printed with a suitable advertisement or with such data to. designate it as a coupon, rcdeeinableif desired, by the advertiser, Further, the sales strip used in the vending machine, disclosed in my co-pending application forms one of the elements of the mechanism for feeding and discharging each envelop section when the sale is made, and for such purpose the continuous strip or envelop sheet has a se.

ries of equispaced apertures, and my present invention also provides for forming the said apertures with such accuracy that when the sheet or strip is made, it is in condition for h-cing inserted in the shape of a reel of sales envelops and to fit with such accuracy in the selling; machine that adjustment or special manipulation for a propereoartion thereof with theother feeding means of the machine is not required. 1

Having thus generally outlined the purposes of the envelop strip or ribbon made by the present invention, the same comprehends, generally, a means for feeding a con- "tinuoustiat or spread sheet of paper or analogous material from a discharging roll to 'a taking-up roll. that coiiporates with means for foldingthe said sheet upon itself at points between the discharging and takeup'rolls so that in passing into the take-up roll it is wound in its folded condition, other means in the more complete nature of invinvention being the coinhining with the tecdinof and folding: means. of printing dcvices for printing one taco otthe sheet he.- tore it is folded upon itself, and in its more specific nature it also provides a means for pasting V the folded sheets at llltQl'VlllS, wherchy to form the folded sheet into a serics o't' sections-of .unitorni size and shape with means for puncturing the folded strips at the pasted or gununed points.

in its still more specific arrangement, my present invention consists in certain details of construction and ,peculiar combination of parts. all of which will he hereinafter fully lion tor use.- Fin. 2, is a frontelevation of one portion of theinachine, the left hand end, and showing the printing and the pasting mechanisms. Fig. 2 is a similar view of theright hand end of the machine, shoW- ing the puncturing, the feed and the envelop sheet take-up mechanism. Fig. 3, is a top plan view of the parts shown in Fig, 2. Fig. 3 is a similar view of the parts'shown in Fig. 24.. Fig. 4:, is a vertical section on the line 4L-4 on Fig. 2, looking in the direction indicated by the arrow. Fig. 5, is a similar view on the .line 5-5 on Fig. 2, and looking in the direction of the arrow. Fig.

6, is a detail perspective view of the paste applying wheel, hereinafter referred to. Fig. 7, is a detail view of the folding device.

Figs. 8 and 9, are cross, sections of the printing mechanism, then the paste apply-.

ihg means, then the folding devices and finally, the puncturing mechanism which, in acting on the folded ribbon or strip, aids in feeding it properly forwardly toward the drawing rolls, from whence the folded and pasted strip, ribbon or envelop sheet, passes to the take-up roll, hereinafter again referred to.

The supporting frame of. the machine comprises a back casting a', that extends the full length of the machine, has a pendent leg a/at the front end formed with afoot portion a and with a pendent leg a at the other end, which also has a foot portion a asshown.

At the rearof. the' back casting a, the frame has a ,bracket bearing an for the drive shaft a that carries the drive pulleya, and a gear a that meshes with a larger gear a on the main shaft 1.01 the printing mechanism, journaled in a cross bearing a of the frame, as clearly shown in Figs. 3 and 4, by'reference to which it will also be seen the shaft 1 carries abevel gear I) that meshes with a similar-gear c on a counter shaft (Z, journaled in bearings b, c", and cl, that extends parallel withthe back frame a the full length thereof, and has, about midway t-h-reof, a bevel gear (1 that meshes with a similar gear d on the shaft .-f that imparts motion to the paste applying devices, and at its extreme end it has another pinion d that meshes with a pinion g on the shaft 9 that drives the perforating mechanism and the envelop ribbon or strip pullingrolls, wit-h wh'ichlthe take-up rolls hereinafter referred to, contact. A

Shaft 1, whose outer end extends into a cog gear 81 that mesh with a cover plate or. casting 2, which is secured by the cross bolts P-3 and 3*,see Fig. 2, carries the printing cylinder 4, whose periphera-l'face is suitably formedffor receiving the printing plates 5, the cylinder as shown being provided for receiving seven of such plates, it being understood, it may be arranged for holding more or less of such plates, as desired.

Adjacent the print ng mechanism the back frame a has a vertical extensional having a stub shaft a, on which a roll of the paper ribbon or sheet is mounted, -said sheet, which is designated X, in practice, being about two inches wide, the width,

however, depending on the size of the stamps, which the vending machines are arranged to sell.

The sheet X passes from the roll. X over guidepulleys 5 and 5and from thence over the impression cylinder or platen 6, which, as is clearly shown in Fig. 2, has; an eccentric bearing '2 controlled by a hand lever T, which, when swung over in the direction of the arrow on Fig. 2 brings the'platen or cylinder 6 into contact with the printing cylinder 4, and when swung in the opposite direction moves the cylinderG and the ribbon X from the printing face, the former movement being restricted by a stop 7.adj ustably mounted on the lever 7, having a-hook b for engaging a stop lug or bolt 3.

The printing 'mechanism includes the main inking cylinder 8, whose shaft SOhas a gear a on the shaft 1.

Cooperating with the roller 8 is an ink font 9 in the nature of a trough, hinged at 90. on the back pasting, see Figs. 1 and 2, in

the outer end of which is mounted a dis-.

charging roll 91 that engages a feed roll 16. journaled in the outer end of an arm 17 fulerumed at 18 on the back casting a and the said arm is so positioned, relatively to the font and the maininking cylinder 8 that the feed roll 16 is norm-ally out of contact with the cylinder 8 and held to' rest on the font 7 roll 91. Y

The arm 17 is intermittently oscillated through by a cam 20 on the shaft21 that carries the feed roll 91 and engages an ad j ustable heel 17 a on the said arm 17 and as it does so, it temporarily raises the feed roll 16 and likewise holds it in contact with the l inking cylinder, 8. I I For regulating the flow of the ink in the font the same has'its front end adjustably supported on the set screw-23, held in the casting bracket 23, see'Fig.-2.

. The ink feed roll carrying shaft 21 has a large cog gear 21 that meshes with a cog gear 21 on the ink cylinder shaft 80 and the back face of the said gear 21" has a bevel gear 21, with which meshes a pinion 24 on a short shaft 24: mounted on the back casting shaftsfjtl and 29 are fixedly connected, that l the inking cylinder, and the" several parts a, see. Fig. 2, that carries a crank disk 25,

the wrist or crank pin 25* of which engages the forked end '26 of an oscillating lever, see Figs. 2 and 5, fulcrumed on a-bracket piece 26*, and whose other forked end 26 engages a stud 27 on a shaft 27, longitudinally slidable in. a hollow bracket 27." and whose front end has a fixed engagement with a triangular bracket 28, to which a pair of are parallel withshaft 27 and which are slidably mounted in the frame brackets 27 -27 and each of which shafts carries an .inkdistributingroller 30-- -3O that engages just'described are codperatively so arranged that a longitudinal reciprocatory movement is imparted to the rolls 3030 over the-face of the inking cylinder so as .to thoroughly distribute the ink fed thereon from the font and feed rolls hereinbefore referredto.

So far as described, it will be readily ap' parent that as the paper strip or ribbon is fed forwardly from left to right iii-Figs. l

and 2, it is engaged by the printing -nieehanisin and operated upon to receive the ad vertisemeuts on the outer side thereof.

In passing from; the'printing mechanism, the printed ribbon orstrip passes over a flat plate or table 31, secured by'braclrets 31 to project, thcrethrough sutliciently to form a bearing for the passing paper ribbon or str p, 11; being held under tension against the r said strip by the coiled springi-ii that issecured at one end to the main frame and at the other end to, the inner end of an arm 32".

I fulerumed under the table or plate 31, and

which carries the roller abutment 32, as

clearly shown in Fig. 2,which also shows a cam lever 32 for engaging the spring attached varn'r'32 for regulating the tension pullof such spring32 l (loacting with the roller isthe paste distributer which forms a particular feature of my invention. he distributer is in-the nature of a pulley or wheel 33liaving a series of .equi-sp'acedfradial paste applying tingers -3d. These fingers, it- Will be observed from Fig. (3,:each consist-of two semi "cylindrical members slightly spaced apart,

so that in engaging the sheet they a iply the ply the paste in two opposing semi-cirla yers designated g -y oirhia'. 10, the

The pasting fingers receive paste on their outer edges only, and to provide for this the said edges are made to engage a paste distributing wheel that is geared with the' paste applying wheel, the distributing wheel- 35 being mounted on a stub shaft 36 having a gear 36 that mesheswith a,lar rer gear 37 mounted in a i 'ertically extgn'ded bracket 37 of the back framed and which gear 37 in turiihas its shaftprovided with a cam 38, the purpose of which will presently appear. The paste applying 'wheel has its shaft geared with the counter shaft (1. see Fig. 3,

and it drives the paste devices by connections, shown in F 2.

The paste supplying means operates subthe gen r stantially the same as does the inlrfout andsupplying means for the prii-iting' met-ha- T118111; As shown inFig. 2 the said paste supplying means includes a pivotally and adjustably mounted font 41 in the discharging endof which is mounted a feed roller 11,

mounted on the shaft is iiiteri'nittently enga roller 42,-

38, and which roller ged by a distributing mounted in the outer end of an arm 43 pivoted at 43 on the back frame and normallydrawn upward by a coiled spring 44-. Arm -13 also has an adjustable stop heel for engaging with the can] 38, it being understood that when the (21111.38 engages the heel L5, as shown in Fig. 2, the distribut- 111g roller 42 engages and transfers the paste to the paste wheel that the radial ,qumming or paste transferring fingers ennui-e. The paper, as it is fed to the pasting means, is also being partially manipulated to provide for the fold, but that part of the ribbon engaged by the pasting fingers remains in the original flat condition and does so dui'iii (T its full passage through the machine. It

will be apparent that the paper ribbon as it passes from the pasting fingers, has the gum or paste only ()Il'OllO face. the inside face, whereas the printing is' on the bark face. To enable the ink'side to become partially dry before the ribbon engaged by the pasting;- devices. the latter are preferably'positioi'uul some distant-e away from the printing end, as shown, but they may, if desired, bd close After the side,.as stated, the actual operation of folding the ribbon and gu nining the folded parts together follows, and that the same may be readily understood, attention is more particularly directed to Figs. 1 hurt 7 of the drawings, from which it will be noticed that the paper strip or ribbon vjust after it passes the paste applying wheel, enters the folding device that bends and folds one half T of the ribbon over and down upon the other or pasted portion.

V 5 flange 46 The folding device shown in detail in Fig 7 consists of a thin metal plate 46,'in practice, of slightly greater widththan that of presser rollers 4747 located just in .ad-

-ance of the puncturing mechanism pres- 16 ently' described, the front-edgeof the said base portion' lfi a guide flange 46 for'one edge (the outer) of the paper ribbon to hold it from moving outwardly duringthe operation of folding the saidstri or'ribbon. The other portion 46 of theplate 46 at the paper entrant end,

extends vertically at right angles to the part 46 as at 46, and front thence ,it bends'down in a gradual curve over the base portion 46'- E (the two members of the folding device being spaced apart) until its other or'discharging end 4L6 lies flatwise on :the otherportion 46, and the upper edge of the said member 46 is bent inwardly to form a guide for guiding andturning the other or inne'redge of the paper ribbon. The -member 46, it will be noticed, is in a plane to the'rear face of the pasting wheel, so that the desired passing of the ribbon under the said wheel is not interfered with.

By arranging and constructing a folding device in the'manner shown and described, it is obvious thatafter properly slipping the end of the ribbon into the said folding de vice and through the same, and drawing it through, until it, in its folded shape, is engaged by the pull or drawing rolls herein,- after again referred to, the said ribbon, from the point where it leaves the printing mech:

anism,.has its inner portion gradually bent upwardly by the folding. device until the said ribbon assumes a substantially L shape, see Fig. 9, and from the point where it enters the said folding device the inner or ver-.

' tical portion of. the ribbon is gradually brought down over the otheror horizontal portion until it lea-ves'the said folding device .when the a said vertical part of the said ribbon is fully bent over and parallel with the other or horizontal part thereof,

and in position to be brought down onto that face of the ribbon having the paste surfaces.

By extending the folding device as shown,

' ample time is given for allowing the pasteto set so that when the two parts of the ribbon ass under the guide and pressure roll-- ers 4 *47", the said two parts will be glued at equi-spaced points.

.The rollers 47%? are mounted'in the vertical plane on stud axles47 47 and one of the rollers 47 extends up through an opening 31 in the table plate 31 as shown, and to provide for adjusting the pressure of the rollers 4l74=7 on the passing folded being turned over to form.

framing, the tension of which is regulated by a cam lever48 mounted on the framing,

as best shown in Fig. 2. The ribbon, now folded upon itself and pastedat properly spaced intervals, passes to the puncturing means, located just in adyanee of the pull or feed rollers, the.construction of which is clearly shown in Figs. 1 and 2, fr0m.which it will be seen that said'puncturi'ng. means consist of a pair of opposing disks 5l-51 mounted on shafts 5l"51 projected from the main frame,-one above'and the other below the table plate 81,

so the oppos- The disk shafts 51 carry-gears 52-52 that mesh, and one of the gears 52 meshe with a cog pinion 56 through the medium of an idler gear 55, the shaft of which pinion 56 is mounted in a horizontal frame bearing 51 and carriesthe'bevel pinion g that meshes with the similar pinion on. the

center or drive shaft 0?, see Fig. 3.

As before stated, owing to the construction of vending machines for which the Williams continuous envelop or sales'strip is moreespecially, intended, the said envelop must have apertures spaced equi-predetermined distances apart, it being also required that the ends of each section of the envelop (meaning the spaces between the apertures) must have its opposite ends closed by pastmg or gumming, whereby to provide small envelops, see Fig. 11.0f a size to conveniently hold one or more postage stamps packed. upon each other.

The upper disk 51 carries a series of radially disposed puncturing studs 52, adjustably mounted, see Fig. 2, so they ma be accurately projected with respect to eac other and with respect to a corres onding series of socketed anvils 53-53 adwstably carried in the peripheral edge of thelower disk or wheel 51, the outer or bearing surfaces of the said anvils being concentric with the peripheral edges of the disk, whereby to oppose the upper disk or wheel face.

The series of punching studs on the upper disk and the socketed anvils on the lowerdisk are relatively so spaced thatas the en-' velop passes the said upper and lower disks, the punchers will engage the envelops and perforate them through the spaces between the circular gummed or adhering portions, or in otherwords the apertures in the envelop are so made that they aresurroimded by the. pasted portions ofithe two folds" of the ribbon or strip. This method, of puncturing the envelop sheet rovid'es for the cutting off the sections of the continuous ribbon in such manner that the opposite 130 57 of the take-up rolls so as to provide for ,v on the ribbon independently,

ceases edges of the section or envelop remain pasted or L edges sufficiently to hold the stamp from sliding laterally within sheet, and thereby lose their proper separation. 1

T he puncturing studs and the hollow anvils that coact therewith are mounted in sections of the disks ail-*5? that are rotatably adjust-able on the other sections of the said disks, see 1 and 2, so that the punc- 'turing studs and the opposing socket anvils may be accurately set for their intended purposes. I

The disks51-51 are geared with each other and the upper disk 51 also gears with an idler gear 55 that receives motion by reason of meshing with the gear 56 on the upper draw roller 57 that also meshes with the lower draw roller-57 see Fig. 2 upper roller being driven from the counter shaft (Z, as shown, and in such direction that the rollers 57-57 travel in the direction inarrow 2, Fig. 2, so as to grip.

dicateo by the the now printed, pasted and folded, and perforated envelop sheet direction of the take-up roll 59. The roll 59 is mounted in a stub shaft 59 'on the upper end of a bearing arm 59, fu'lcrumed at the lower end on the stud 59 on the leg portion of the main frame'casting -andheld under tension to keep the constantly filling roll 5.) pressed in the direction of the lower roller the constantly increasing diameter of the wound endless-envelop or strip as it passes in its complete form the said rolls 5151 is not arrested fromthe starting to the de-' livery point, a complete operation is being continuously carried on, and this is rendered possiblesince the several parts operate interdepende'ntly and are not designed for acting that is, the said several mechanisms are so designed that the desired operations can only be accurately effected by continuousl moving the ribbon, and having the seven mechanisms operate on different parts thereof simultaneously.

In order that a more positive and perfect crease may be imparted to the sales'strip in passing through the folding mechanism 46, a beveleddisk 60 mounted on the arm (30 which is pivoted a 60 and held in engagement with the strip and folding mechanism 46, by the tension spring 60, is provided, as

glued together to close up the said the continuous the and pull it in the vfolding means and 1 will be seen from the drawings, to effect the purposes above enumerated.
