Any air-forcing device which shall directa current of air against the exposed prin ted surface will answer the purpose.
  • the feeding-rolls 9 9 and ll-11 are geared to rotate in synchronism, and they are driven with due regard to the travel of the paper or web through the printing mechanism.
  • the printing devices may be of any well-known form, such as are now used forprinting calico and other fabrics or such as have heretofore been employed for printing bag-blanks and the like. It is therefore unnecessary to enter into a detailed description of the printing apparatus.
  • the web or sheet passes to intermittently-acting rolls 12 and 13, which are designed to score, crease, or indent the web on the lines of future folding.
  • one roll is formed or furnished with slightly-projecting ribs,and the other is made with corresponding grooves or depressions, the two being made to register with accuracy.
  • the character and arrangement of the scoring-ribs and grooves will vary according to the nature of the web andthe dimensions and form of the package to be produced, Fig. 1S showing the scored or indented blank, and thus illustrating in plane projection the surface of the rolls.
  • the scoring-rolls 12 and 13 are geared to rotate at equal surface speeds and receive motion through the medium of a ratchet-wheel 14, carried by roll 12, which wheel is turned by a pawl 15, carried by an bottom of the bag or package.
  • Rack 17 is pivotally supported upon the main frame of the machine and is actuated by a cam 18 on the end of lower roll 11. The motion may be positively effected in both directions by use of a curved cam or in one direction only by use of an open cam, in which latter case gravity or a spring will be utilized to return the rack to its normal or depressed position.
  • the rolls 12 and 13 act intermittently, while rolls 11 11 act continuously and turn at a constant rate of speed. From this it follows that a certain amount of slack accumulates between the two pairs of rolls during the periods of inaction of the rolls 12 13. To take care of this and to prevent the web from being buckled, torn, or distigured, I place upon that portion lying between the feeding and the scoring rolls a roller 1S, having ilanged or enlarged ends. This roller by reason of its weight keeps the web taut and straight, acting in amanner similar to a belttightener, yet is light enough to be readily lifted when the scoring-rolls turn, so that no hindrance to their operation is caused.
  • rollsI am enabled to score or indent the stock without subjecting it to undue tension or strain, having always a surplus in advance of rolls 11 when the scoring is performed, ⁇ vhich surplus is under the very slight tension of roller 18.
  • Roll 19 indicates another roll, geared to rotate in unison with roller 12 and in the same direction through the aid of an intermediate pinion 20.
  • Roll 19 is designed, with the aid of a smaller roll 21, to apply paste to the blank at such point as will serve for securing the To enable the roll to perform this latterfunction, it is formed or furnished with a projection 22, which at one point in the rotation of the roll makes con tact with a paste-roller or equivalent pastesupplying body 23 and at another-point therein bears against and delivers paste to the web, supported at the time by the upper roller 21, the point of such application being indicated in Figs. 19, 20, and 21.
  • a bag length or blank is severed therefrom by a vertically reciprocating or oscillating knife 21, (shown in Fig. 1, but more clearlyV in Figs. 2, 5, and 7,) the parts being so timed or related that the knife acts only while the web lengt-h in advance of rolls 19 21 is at rest.
  • the intermittent action of the rolls 12 and 13 is designed to preclude any tearing of or injury to the web by the scoring or creasing rolls, which might occur if said rolls drew the web directly from the rolls 11; but rolls 19 and 21, being geared to turn at the same surface speed as the scoring-rol 1s, will advance the web at precisely the rate at which it is delivered by the scoring-rolls.

` T0 a/ZZ whom, tana/y concern:
Be it known that I, RUFUs L. PATTERSON, a citizen of the United States, residing at Durham, in the county-ofDurham and State of North Carolina, have invent'ed'certain new and useful Improvements in* Machines 'for Packing'Merchandise, of f which thefollowing is a speciiication.- I
My inventiony pertains to machinery -for `packll,merchandise; and is designed in its complete-form to print afweb of paper in one" or more colors, to cut from said web proper,
lengths for the production of bags or packages, to fold 'and pastethe paper into the required form, tomeasure andweigh the properJ charges, to deposit them into thelprep'ared-` bags or packages,and, finally, to seal and de-i liver the finished packages, all automatically.`
Referring to the accompanyingdrawings,A Figurel is aside elevation:y of the -printingg apparatus, showingthe *package forming mechanism inend-elevation; Fig. l,a-ver`-4 tical sectional View taken'in the'plan'e of :the

At the present time there is a large yand vgrowing demand for packaged goods, especially in the line of lstaple articles of mer- 1 ichandiseJ-such as coffee, tea, sugar, spices,
breakfast-foods, and thelikel-and the present invention is designed lto produce a machine by which" the packaging of such goods may be speedily and efficientlyV performed. =Gertain parts of the machine or certain groups iofm'echa'ni'sm therein are susceptible of use independently of others-Fas, for instance,the ,measuring and weigh-ingdvices maybe used independently ofthe printing or of the packzaging mechanism,"the printing and bag-forming mechanism may be used independently of the measuring or weighing mechanism,and theprinting mechanism may be eliminated :and the measuring or the 'measuring and `weighing mechanism used eonjointly with the package-forming and packing devices. I`
the'refore mean. tolclai'm the As epaara'temech- {anisrns 'and groups of mechanismsindepend- 'ently of y theircombination in one organized s structure andI also? to claim the complete jstiuct'ure, wherein all the parts are designed with 'reference to'each other and'to their operation inipropertiniel and 'sequence A In many ofits'details the embodiment of fthe invention may be varied; but I' shall set 4forth'thatA construction and arrangementof parts which I have fully developedfand which isinovv` believed by me to be themost ableembodiment of the invention. Referring first to'Fig. Vl, I have represented a Web'or roll of paper.l 1, mounted upon a shaft or axle 2, carried in brackets or supports upon a suitable frame 3,which also carries feedrollers 4 and one or more printingv mechanisms 5. `The feed-rollers and printing mechanisms receive motion through bevel-gears 6 and 7 from a shaft 8, which, in turn, may receive its motion from any convenient source. In practice it is deemed desirable to print the bag or package blanks in two or more co1- ors, and where this is desired rIprovide a pluralityof printing. mechanisms 5, which may' be of any approved type, andI pass the web or paper from the roll l first between the feeding-rollers 4 4 and then between the form-rolls and the impression-rolls of the printing mech- Vanism's 5, thence between a second pair of feed-Tolls 9 9, thence upward over a drum or rotary support 10, and back to a third pair of feed-rolls 11 vl1.
IOO
The feed-rolls 9 9 are cut away between their ends, so as to bear only upon the unprintcd edges of the web or sheet. ln passing from the rolls 9 9 to the rolls 11 11 the paper or web is carried a considerable distance through the air with its two faces eX- posed thereto, the drum 10 serving to separate said faces and to permit a free access of air to the printed surface.
The drum 1() is constructed in the manner represented in Fig. 1a or in any equivalent form, whereby it is adapted to sustain the paper or web at its edges, while leaving the intervening printed surface free from contact with any portion of the drum or other body. As seen in Fig. 1, the drum 10 consists simply of two flanged or rimmed wheels, each having a circumferential face of suilicient width to sustain one edge ot' the paper, the two wheels being separated such distances as to accommodate the width of the web or sheet between their flan ges.
Printers ink dries rapidly when exposed to a moving air-current, and in order that it may dry during the passage of the web or sheet from the feeding-rolls 9 to the feeding-rolls 1l a fan 12 or other air-forcing device is arranged to direct a current of air against the printed surface of the web between these points. In the drawings, Figs. 1 and 1, I have represented the fan l2 as carried by a shaft passing through tubular axles or journals of the drum-wheels 10; but this is merely suggestive and need not he followed in practice. Any air-forcing device which shall directa current of air against the exposed prin ted surface will answer the purpose.
As indicated in Fig. 1, the feeding-rolls 9 9 and ll-11 are geared to rotate in synchronism, and they are driven with due regard to the travel of the paper or web through the printing mechanism.
It will of course be understood that the printing devices may be of any well-known form, such as are now used forprinting calico and other fabrics or such as have heretofore been employed for printing bag-blanks and the like. It is therefore unnecessary to enter into a detailed description of the printing apparatus.
From the feed-rolls 11 11 the web or sheet passes to intermittently-acting rolls 12 and 13, which are designed to score, crease, or indent the web on the lines of future folding. To this end one roll is formed or furnished with slightly-projecting ribs,and the other is made with corresponding grooves or depressions, the two being made to register with accuracy. The character and arrangement of the scoring-ribs and grooves will vary according to the nature of the web andthe dimensions and form of the package to be produced, Fig. 1S showing the scored or indented blank, and thus illustrating in plane projection the surface of the rolls. The scoring- rolls 12 and 13 are geared to rotate at equal surface speeds and receive motion through the medium of a ratchet-wheel 14, carried by roll 12, which wheel is turned by a pawl 15, carried by an bottom of the bag or package.
arm 1G, secured to or made integral with a pinion loosely mounted upon the shaft or gudgeen of roll 12 and rotated iirst in one and then in the other direction by a segmental rack 17. Rack 17 is pivotally supported upon the main frame of the machine and is actuated by a cam 18 on the end of lower roll 11. The motion may be positively effected in both directions by use of a curved cam or in one direction only by use of an open cam, in which latter case gravity or a spring will be utilized to return the rack to its normal or depressed position.
As pointed out, the rolls 12 and 13 act intermittently, while rolls 11 11 act continuously and turn at a constant rate of speed. From this it follows that a certain amount of slack accumulates between the two pairs of rolls during the periods of inaction of the rolls 12 13. To take care of this and to prevent the web from being buckled, torn, or distigured, I place upon that portion lying between the feeding and the scoring rolls a roller 1S, having ilanged or enlarged ends. This roller by reason of its weight keeps the web taut and straight, acting in amanner similar to a belttightener, yet is light enough to be readily lifted when the scoring-rolls turn, so that no hindrance to their operation is caused. By this combination of rollsI am enabled to score or indent the stock without subjecting it to undue tension or strain, having always a surplus in advance of rolls 11 when the scoring is performed,\vhich surplus is under the very slight tension of roller 18.
19 indicates another roll, geared to rotate in unison with roller 12 and in the same direction through the aid of an intermediate pinion 20. Roll 19 is designed, with the aid of a smaller roll 21, to apply paste to the blank at such point as will serve for securing the To enable the roll to perform this latterfunction, it is formed or furnished with a projection 22, which at one point in the rotation of the roll makes con tact with a paste-roller or equivalent pastesupplying body 23 and at another-point therein bears against and delivers paste to the web, supported at the time by the upper roller 21, the point of such application being indicated in Figs. 19, 20, and 21. Vhen the web is advanced a proper distance beyond the rolls 19 2l, a bag length or blank is severed therefrom by a vertically reciprocating or oscillating knife 21, (shown in Fig. 1, but more clearlyV in Figs. 2, 5, and 7,) the parts being so timed or related that the knife acts only while the web lengt-h in advance of rolls 19 21 is at rest. The intermittent action of the rolls 12 and 13 is designed to preclude any tearing of or injury to the web by the scoring or creasing rolls, which might occur if said rolls drew the web directly from the rolls 11; but rolls 19 and 21, being geared to turn at the same surface speed as the scoring-rol 1s, will advance the web at precisely the rate at which it is delivered by the scoring-rolls.
IOO
IIO
The precise mode of actuating the knife or cutter is immaterial, though I have shown the knife in Figs. 5 and 7 pivoted at one end to a rigid support and connected by a link at` its opposite end to a lever 26 of the first order,
the free end of which is furnished with an;
antifriction-roller 27, which bears upon the edge or circumference of a cam 28, carried by a shaft 29. As willbe pointed out, shjaft 29 carries a series of cams, by or through which the appropriate motions are imparted to each and all of the folding devices by which the bag or package is brought into shape. v It receives motion from any convenient prime inotor through a pinion 30, carried by a band-Y wheel shaft 3l`and meshing with a gear-wheel upon shaft 29, as indicated by dotted lines in Figi. 2, though any equivalent driving-rig may be employed. Before being severed from4 the` web the bag length or blank is carried across and caused tolle upon a horizontal bed or support, at one side of which is located astationary shear edge or blade, with which the cutter 24' coacts. a t
The manner of folding up the blank to producea bag or package is illustrated in Figs. 9 to 14, inclusive.
The bed or support just mentioned is formed by two movable horizontal plates or folders 32 and 33, which are normally drawn apart a distance equal to the width of the intended bag or package or until their proximate edges,
just overlap the upper edges of two vertical plates 34 and-35, constituting the side walls of a mold in which the bag or packageis fashioned. Between the plates 34 and 35 there is arranged a yielding bed or block 36,y which,
bridgingthe space between the folders 32 and 33, forms a support for the blank. Directly above theblockorbed 36 there is locatedaform or pattern-block 37, about which the bag or package is wrapped orfolded. pattern-block is carried by a vertically-reciprocating head or slide 38, to which one end of the form is made fast, and standing normally somewhat above the level ofthe folders 32 and 33 it permits the bag-blank to pass beneath and between it and the .block 36.
When the blankis thus-placed and' is severed from the web, the form or pattern-block 37 is caused to descend, carrying before it the blank and the block 36 beneath it; but the side .portionsfof the blank, supported, as
they are, by the folders 32 and 33, are turned planes, as indicated inl upward into vertical Fig.r 10.
It has already been explained that paste isl applied to the blank at one point in passing between rolls 19 and 21 to insure the sealing of the bottom of the bag. That portion of the blank thus supplied with paste overhan gs the'folders 32 33, and consequentlydoes not f give off the paste to said parts, which would of course cause trouble inthe working of the machine. To supply paste for the longitudinal seam or joint of the bag or package, there is arranged above the folder 33 apaste- This form ork receptacle providedwith a rollerI 40 or equivalent delivering device-and `carried bya le-v ver 41, to which is applieda spring 42, a counterweight, or equivalent lifting device to hold the paste-receptacle and roller normallyabove the lever of the bag-blank. Projecting from` the pivot shaft or spindle 43 of the 'lever 41 is an arm 44, carrying at its end an antifriction-roller 45, and securedto or projecting from the h ead or slideY 38'is a lug 46, which as the form or pattern-block descends bears,
against roll 45, depresses arm44, and thereby lowers the pastereceptacle 39 until its roll- 40 bears upon the bag-,blank lying upon folderv 33.- The lug 46 is of such vertical measurement,
as to hold the paste-roller in contact with the blank until said blank is almost ,drawn out from beneath it by thel continuing descent of the form or pattern-block37 but that just be-` fore the edge is reached the arm- 44 is released and thepaste-recepta'cle and its roll arepermitted to rise.V The vspring 42 or its equiva lenta weight-serves tovelev'ate thepaste-V receptacle vwhen it is thusmade free to rise, a spring being.preferred,because of its more prompt action. pattern-block carries the projecting endof the blank against a Vfixed folder-plate47 of the'form shown in Fig. 11. .This folder occupies averticalposition just alittle outof plane with` the end of bed or block 36 and of pattern-block or form 37, so that as the blank is carried down the protruding portion of the lower side ofthe package beingformed is turned or folded inward andupward, as
'In descending `the former ICO` indicated inFig.- 11, thus makingthe irst bottom fold. The upper edge of the folder.
47 is highest at the middle andinclines thence downward toward each side to ycause -the proper formation of the bottom fold. The,
pattern-block or form having`,been carried down to the position shown in Figs. 10 and 11 and the sides and bottomhavingbeen thus IIO given their initial folds, a horizontally-recip-` rocating head. 48 moves inward toward the form or pattern-block37, carrying with it the folder plate or blade 32, Awhich when moved its full distance inward laps slightly overor.
upon the pattern-block oriform 37 and .over
or upon the paper thereon. Owing to the preliminary. creasingA or scoring of thepaper, the portion against which the folder 32 bears will be caused to lie-fiat upon the upper face ofthe form or pattern-block,- notwithstanding the-slight distance to whichitis overlapped bythe folder 32. `The reason for giving so slight a projection or overhang of the folder is that it is desirableto leave uncovered as large. a part of the upper faceiof the blanky as practicable when the flap or fold is laid upon the form or pattern-block, so that the second flap or fold previously. pasted may be laid fairly upon it without overlapping the `folder32. -Ati the same time` that the folderl 32 moves inward, or shortly thereafter,
folder 33 which is carried bya head 49, simif` larly-moves inward from the opposite side,`
its range of movement being greater than that of folder 32 advisably, though Anot necessarily. Y
To insure the proper laying of the wider second flap or fold upon the narrower rst flap or fold, the folder 33 is hinged or loosely attached to head 49 and is normally elevated at its forward or inner edge by a spring 50. The elevation ofthe folder is limited in any convenient way and is slight in any event, but is suiiicient to prevent pressing the wider flap down fiat upon the narrower one or upon the form beneathuntil the folder has reached the limit of its inward movement. The narrower flap being pressed flatly upon the form or pattern-block and the wider one left free to rise by reason of the natural spring or resilience of the paper, the wider one will always fall upon the narrower one. To insure perfect contact and good'adhesion, the folder 33 is depressed by a plunger or head 51 after reaching the position indicated in Fig. 12. At or Ajust before the moment that the head or plunger 51 bears upon the folder 33 and presses it down upon the flap or fold of the package the folder 32 withdraws, so that there shall be no interference of one folder with the other and so, also, that if paste is squeezed from between the two flaps it shall not foul the folder .lust after the folder 33 performs its work, or it might be simultaneously therewith, two horizontally-moving heads 52 and 53, carryingbottom-folding blades 54 and 55, moveinward toward each other, as indicated in Fig. 13, and make the second and third bottom folds. Lastly a head 56 descends, carrying with it a blade or folder 57, which makes the fourth andi-ast bottom fold. This blade is made somewhat long and is quite elastic,the several thicknesses produced by the successive folds being liable to necessitate a certain amount of yielding or adaptation of the folder 57. It is likewise important that a quite firm though elastic pressure be given the last fold in order to give a goed finish to the bottom, and particularly to insure adhesion of the bottom fold to those preceding it.
It will be remembered that andai) of paste is applied torthebagmlapk beforel the latter is severed from the web, and this at a point which afterward becomes the first fold of the bottom. The subsequent folds each overlap this dab of paste and are thereby caused to adhere to the first or inner fold.
It will be seen that by the foregoing mechanism there is formed a complete bag or package open at one end and suited to re` ceive merchandise. This may be of paper of any desired weight and texture or of other suitable material, a good Manila paper being deemed advisable ordinarily. The several operations take place in suchquick suceession that the paste has no opportunity to dry or set before the parts are laid and pressed together; but care must be taken to use a good grade of paste, glue, or mucilage or vcam 6i.

This end piece is carried by a central rod or stem 59, preferablypolygonal in section, which passes iongitudinallythrough the pattern-block or form,
`and extending some distance outward beyond form their operations in proper order and time, and to insure the maintenance of any relative adjustment that may be made it is deemed advantageous to place upon a comm on shaft the various cams for actuating said folders, as also that for carrying the bag from the form into the holder or carrier. vrlhis arrangement is illustrated in Figs. i and 5, where the shaft 29 is represented as bearing the various cams mentioned. Referring 1i rst to Fig. 1, it will be seen that the verticallysliding head 38, which carries the patternblock or form, is connected by a link 61 with one arm of a lever (32 of the first order, the other arm of which has alaterally-projecting stud orroller 63, which is acted upon by a rThe cam serves to lift the sliding head and pattern-block or form, which may descend by spring or gravity or be positively depressed through the use of a covered instead of an open cam. As shown in Fig. 5,
`the side-folders 32 and are actuated by levers 65 and 6b', moved by grooved cams (37 and (5S, suitable links being employed to connect the folder-carrying heads 4S and 49 with In like manner the heads 52 and 53, carrying the bottom or end folders 5l and 55, are connected by links with levers 69 and 70, which are moved horizontally by grooved cams 71 and 72, carried by The vertically-moving.head 5G, carrying the end or bottom folder 57, is connected by a link with a vertically-oscillating lever 73, carrying at the opposite end a stud or roller 7st, which bears upon the periphery or enters the slot of a cam 75, likewise carried by shaft 2Q.
To cause the removal of the prepared bag or package from the form or pattern-block 37 and its delivery to a suitable holder or carrier, I provide the mechanism illustrated in Fig. et, where 7 G indicates a rigid guide-bar upon which is arranged a sliding block or head 7 7 IOO IIO
The block 77 is provided with a fork open at its lowerendto receive the pin 60 of rod 59 when the bag form orpattern-block 37 is elevated. e Block'77 is connected byalink With the upper end of a lever 78, which is pivoted orfulcrumed at its lower'end and isconnected by a draw-bar 79 with the free or moving 1 end of'a'leve'rfSO, which is pivoted or fu1- `nishedwith aAlaterallyiprojecting stud or,

In this Way the bagisremoved from the pattern-block or formand carried into a suitable holder or carrier 84.'
In all cases Where open cams are employed springs may be used to give movement inthe direction opposite to that produced bythe cam, or covered cams may be used throughout. It may befound preferable to use the open cams and springs to permit the parts to yield in the event of encountering obstacles when moving in operative direction.l v Referring next to Figs. 2, 3, and 4,'the construction and arrangement of the carrier by which the bags are delivered to and from the charging devices will be explained.
It is proper to mention that While paper has been spoken of in the foregoing description as the material of which the bags or packages are made'any suitable materialpaper, cloth, cardboard, or other-capable of being oper- -ated upon in the manner and by the means described may be used. So, too, the relative dimensions of the package maybe varied and the terms sides, ends, &c., are to be understood as referring to a packagehaving the general relation of dimensions herein set forth, though they might require to be transposed if the proportions-were so far changed as to 4make those parts the ends which are herein referred to as sides The folding or bag-forming mechanism is carried by an end extension of a frame S5, in and upon which frame are mounted suitable k appliancesl for charging the bags or packages and for closing and sealing them. Frame-e5 supports a horizontal bed or table SG, from which rises a column or standard 87, which supports mechanism for measuring or Weighing or for measuring and weighing the charges of material and delivering the same into the prepared bags or packages.
The mechanism for receiving, holding, and conveying the bags or packages consists of an. endless chain, composed ofopen-ended boxes 8e4, connected by links V88, the' pins'of which are advisably furnished'with rollers-89.' The chain .thus formed passes aboutffour sets of rollers 9091, located at the ends of.:y `the bed or ltable 86,- and at points directly be-` low, the rolls 91 being notched to receivethe l rollers S9, "and thnsto'act as sprocket-Wheels for giving motion to the chain'n-The snm'allf rollers 891facilitate th'e-travelwofgthe chain ovei-.thetop of the bedforztable 86 and also? ,j 4 over 'a'sh'ort' vertical xbed, orsupport .92 atfthev 1 1' j.V .l1

bag form both vertically and horizontally. So, also, the end piece 58 is timed to advance with the bag to carry it into the carrier box or holder-and to recede, leaving the bag in said box or holder, before the carrier-chain again begins to move. The bag will be made to fit so snugly within the box or holder as to preclude liability ot' being withdrawn by the plunger or carrier 58, or, if found necessary, friction devices may be added to retain it; but as this is set forth in an application filed in my name on the 20th day ot August, 1807, and designated by Serial No. 048,930 it need not be further described herein. t
Standard 87 carries or sustains a hopper 107, into which and from which is delivered the measured charge for each successive bag or package. The hopper has a contracted discharge pipe or outlet which is so located that each bag in turn shall come to rest directly beneath and in line with it, as indicated in Figs. 3 and 6, and the measuring and weighing mechanism is timed to deliver into the hopper at those periods when a bag is in such It is desirable that the charge be leveled in each bag preparatory to closingits top in order that the folds may be neatly and accurately made and properly secured. This may be done by subjecting the box or holder to a shaking or jogging motion just after the chargeis introduced or by a pluugeror presserhead entering the mouth of the bag and bearing upon the contents. 'lhe selection will depend somewhat upon the character of the material being packed and the facility or lack of facility of movement of its particles. I have shown the presser-head 108 and shall ordinarily employ such device, finding that with most substances it gives very satisfactory results. The presser-head is shown in Figs. 3 and 8 and is preferably made hollow to constitute a paste-receptacle, one of its side walls being furnished with a paste-roller 109, as shown in said figures. lt is carried by a horizontal arm 110, secured to a vertical rod or stem 111, which is elevated by a spring 112 and is periodically lowered by a cam 113, acting upon a lever or radius-bar 114, which is connected by a link 115 with the rod or stem 111. Cam 113 is carried bya shaft 11G, which receives motion through gearing from shaft 29. In descending into and withdrawing from the mouth ofl the bag or package the presser-head 108 carries its paste-roller 109 over the inner face of one wall ot the bag, applying a suitable quantity of paste thereto.
In Fig. 28 I have represented abar or rail 170 with a wavy or corrugated upper face secured to the bed or table 86 in such position that as the carriers or holders 8l pass from the point where the charge is introduced to the point where the mouth or top of the package is closed the holder, and consequently the package and its contents, shall be rapidly shaken by reason of the rollers 89 of the carriers riding over the corrugated surface. There will be a like rail at either side of the carrier-chain. i j
It is a common practice to introduce into packages of this vgeneral character acard, ticket,-or coupon for advertisingpurposes or the like, and to supply and introduce such l cards or tickets there is provided the apparatus illustrated in Fig. 8. This comprises a paper-roll 117, from which the paper strip passes to and between printing and impression rolls 118 119 of a printing apparatus of ordinary construction. vBetween these rolls and the presser-head 108 is a bed or table 120, upon which the strip rests and beyond which it projects beneath the presser-head and over the mouth of the bag. The outer edge of the table 120 is made slightly beveling to constitute a fixed shear-blade, and the proximate side of the presser-head has its lower edge similarly formed, so that as the head passes the table it shall shear ofl the protruding length of paper and carry it into the bag or package. To cause the periodical advance ofV the paper strip, any suitable intermittent feeding mechanism may be adopted-such, for instance, as that shown in Fig. 3-for turning the sprocket-wheels 01 to advance the carrier-chain. The card-printer may be omitted or thrown out of action when not needed.
.Inst after the withdrawal of the presserhead the carrier-chain advances one step, and thereby carries the charged bag or package into position to be acted upon by the closing or end-folding mechanism. As shown in Fig. 3 and on a larger scale in Figs. 15, 16, and 17, this consists of a swinging folder 121, two horizontally-moving side -folders or blades 122 and 123, and a fixed plate 124, beneath which the package is carried to produce the final fold and to press and iron down the several folds. The plate may be a part or continuation of the guard-plate 94 or a separate plate in plane with the end thereof. In closing the mouth of the bag or package the swinging folder 121 rst, comes into action. It is merely an arm mounted upon a rockshaft 125 and carrying a pointed or V-shaped plate 120, which striking the side of the bag above its contents folds it inward over-the top of the package. Motion is given to the rock-shaft by a rod 127, connected at one end to a radial arm 128 of said rock-shaft and at the other end to the vertical rod or stem 111, by which the presser-head 108 is raised and lowered. Obviously, however, the special form and arrangement of cams or gearing for effecting this and other movements are relatively unimportant and may be varied as desired.
The side- folders 122 and 123 are simply two flat blades or plates, respectively carried by levers 120 and 130, the lower and shorter arms of which levers are connect-cd by a toggle 131, which in turn is connected with one end of a IOO IIO
lever or radius-bar 132. Said bar or lever is quickly raised and lowered at intervals by a covered cam 133 on shaft 116, (shown in Figs. 3 and 6,) said movements taking place during or just after the backward movement of folder-plate 126. By arranging the side-fold` ers to-start inward beforethe folder-plate 126 is entirely 4withdrawn the firstA fold is prevented from rising before the side folds are laid upon it.
Tofenable the foldingblades or plates to adapt themselves readily to any sligh ty variation in the height to which material stands in the bag or package and to render their action elastic and yielding, each plate is held in place by a screw 170, passing through a hole in the plate slightly larger than the body of the screw, the head of the screw being set just a little higher than the plate and the top of each arm or lever129 1 30 being slightly rounded or beveled at the rear or outer side, as shown in Fig. 16. Near the forward or inner edge of the top face of each lever 129 130 a second screw 171 is passed vthrough a hole in the folder or blade lying thereon, its head being kept some distance above the plateand a spiral spring` being arranged between the screw-head and the plate, as seen in Fig. 16.
It has been explained that paste is applied to the inner faceof one wall of the bag-mouth before the folding of the end begins, and it will be seen upon referring to the drawings, Figs. 3 and 15, that it isV applied to that face or wall of which the yfinal fold is formed. By making the bag of such length that the side folds at the top or end cannotmeet the paste will be exposed between theinturned edges of the final fold, so that when said fold or flap is pressed down upon the-preceding folds or iiaps it will adhere thereto. By applying paste somewhat liberally it may be caused to 'sfeadiaterall and thus to insure perfect sealing, while the folds beneath and the ina serted card or ticket preclude the paste or moisture therefrom reaching the contents of the package.
Itwill be observed upon referring to Fig. 3 that the sealed bag or package passes from the folding devices directly to and beneath the plate 124, and thence beneath the guard 94, which latter may be heated, as described, or left unheated and allowed to act by pressure alone. It is deemed desirable to have the presser 108 and the folder-blade 126 act at thesame time, but upon successive packages, because thereby the periods of res't of the carrier may be made quite short. Bybeing held beneath the plate 124 and the guard 94 during several periods of advance and rest of the carrier the effective sealing of the package is insured, the paste being thus given time to set and dry thoroughly before being subjected t the expanding force of the compressed charge when the latter is of an elastic nature, as in the case of tea and various other substances.
l The holders or boxes 484 pass successively over the end of table or bed 86 and out from under the guard 94, eachin turn coming to rest in a horizontal position at a point between the rolls or wheels 9() and 91. While tlleyholder is in -this position, an ejector134 l enters at thebase or inner end ofthe box or holder and passing through the samefromV devices may be substituted for these, or the j arm 121 may carry a paste-roller or series ot' rollers to apply paste to the several flaps or folds of the upper end, as villustrated. in Fig. 27. f The successive steps performed inv making the bag or package are illustrated in Figs. 19 to 26, inclusive; but as these operations have been quite fully detailed further description here is unnecessary. Any suitable measuring or weighing or measuring and weighing mechanism may be employed to supply the bags or packages; but that illustrated in Fig.. vis preferred. The material to be packed is fed :from an elevated bin or stock-hopper through a trunk or spout 136 (one or more) to a hollow cylinder 137, within which rotates a chambered or pocketed measuring-wheel or a plurality of such wheels. If more than. one is used,.the cylindrical shell 137 is partitioned to give to each a separate spaceor chamber, i Y The construction andy arrangement ofthe measuring-wheel andits actuating mechan-v ism are best shown in Figs. 29 and 30,though they will also be found on a smaller scale in Fig. 6. Themeasuring-whcel is somewhat smaller` than the interior of the cylinder and is set eccentrically therein, so as to be in close proximity tov one of its sides, while the space between the opposite side and the pee riphery of the wheel is occupied bya drib bling-roll 138, thev surface of which may be smooth, milled, `iiuted, pitted, or.y otherwise formed to suit the material being-gfed.- The measuring-wheel has aseries of. cells, pock-v ets, or compartments of like'and deiinite capacity, so that by turning said wheel dilfen. ent distances a single charge or multiples of such charge may be delivered.l Tol turnfthe wheel, its shaft or axle 139 has securedupon IOO IIO
it a ratchet-wheel 140, ,which is engaged by a dog or pawl 141, carried by a lpinion 142, mounted loosely upon said shaft or axle.
segmental rack 143, turning about a pivot and having an actuating-arm connectedby a rod or pitman 144, with a radius-leaner lever 145, v moved by a cam 146, serves .to oscillate the rack and to turn the pinion iirst in one and then in the other direction. In this way the dog or pawl is caused alternately to engage with and to ride back over the teeth of ratchet-wheel 140, and consequently the wheel is turned at intervals, but always in the same direction. The actuating-arm of rack 143 is slotted, so that by setting the bolt 147, connecting it with rod or pitman 144, nearer to or farther from the pivot of the rack the throw of the latter may be varied and the extent of rotation of the measuring-wheel at each operation regulated and determined. The dribbling-roll 13S is driven by a light belt 143 from any convenient rotating shaft or member, the friction ofthe belt being so slight that the roll may be locked without stopping the belt or doing injury to anyT part of the mechanism. Secured upon the shaft of said roll 138 is a ratchet-wheel 149, which is engaged at times by a locking-dog or detent 150 in the form of an elbow-lever pivoted to the end face of the cylinder or shell 137. Beneath the measuring-wheel is a scale-pan 151, carried by a scale-beam 152, hung upon knifeedge bearings, as indicated, and provided with an adj ustable balance-weight 153. This pan is provided with spring-sustained doors or gates constituting a bottom, the gates being provided with actuating arms or levers 154, which overlap at their ends and are actuated at stated intervals by a lever or radiusbar 155, connected by a rod 156 with a second lever or radius-bar 157, which is depressed at stated times by a pin 158, projecting from the side face of cam-wheel 146. A spring 159, applied to lever or radius-bar 155, overcomes the weight of said lever and the actuating members connected therewith and normally relieves the gate-levers 154 entirely of their weight or influence, so that the delicacy of action of the scale shall not be interfered with. The connection between lever 155 and the gate-levers 154 is formed by a pin projecting from one into an enlarged eye or opening in the other, so that normally there is no contact between them. The weight 153 is so set as to slightly overbalance the charge deposited in the scale-pan by the measuringwheel, and the dribbling-roll 133is intended to complete the charge by the gradual addition of the small amount required for that purpose. To set the dribbling-roll in action, the pinionV 142 has attached to it an arm 160, which just as the rack completes its throw in direction to rotate the measuring-wheel engages one arm of a trip-lever16l,the other arm of which is thereby thrown upward beneath the horizontal arm of detent 150 and withdraws its nose from engagement with ratchet-wheel 149, thereby making the dribbling-roll free to rotate. When the scale-pan is fully charged, the dribbling-roll should of course cease to deliver material to the pan, and hence a hook or slotted link 162, carried by the scale-beam, engages over ahorizontal lever 163, connected with tho detent 150, and
throws said detent into engagement with the ratchet-whccl149, stopping its rotation instantly as the pan begins to descend. Just after this occurs the pin 158 acts upon lever 157 and causes the gates to open, and thus to empty the pan.
A spring 164 is provided to elevate the bed or support 36, as shown in Fig. 4.
The primary power-shaft 31 of the machine carries a fast pulley 166, a loose pulley 167, and a pinion 30, which latter gives motion to a large gear-wheel on shaft 29, as shown in Figs. 2 and 3, and from a bevel-pinion 169 on the end of shaft 29 motion is transmitted to the printing-cylinders through suitable intel'- mediate shafts and gearing, as shown in the same iigures.
