T0 all whom tm/ay concern certain new. and use'ful Improverr'ients in Ap-paratus'for Mak-ing Bagspr Pockets, of which the following .isa specification.

This invention lrelates to apparatus for making bags`orvp`ockets from flat sheets of paper or other. material, an d itrefers to apparatus of the -kmd in which 'plunger actuated folding devices are employed.

It has for its object to p/rov-ide a simple and efficient form of apparatus of this class in which the formation of the pocket is comit is designed vmore particularly for the production of so-called 'block bottom pockets` ofthe type where, .after the bottom and the two sides are formed, the remaining open sides. are closed by two side folds being tucked in first, the bottom 'edges beingA folded on top of these, the two last foldsof the edgesvvof thesheet to which paste may have been previously applied upon the inside, the paste holding the. pocket together; j

the pocket when finished thus presenting only .oneopen end...

. A machine constructed in accordance with the present invention may moreover, by duplicating certain portions of the folding mechanism, be arranged to produce bot h a pocket and shell atone operation, the said pocket being placed in vthe shell, whereby the hand labor heretofore .employed to eectv this operation is dispensed with.

In order that the invention may be vthe better understood, drawings are appended illustrating two forms of the inventiomand in which Figure 1. is a front elevation partlyT m section and with certain parts omitted. Figs. 2. 3 and ll show various stages in the formation of the4 box.

partl)7 in 'section of the saidalternative fold- Be it known that I, WALTER' Evnnn'r'rl Morane, a citiaen ofthe United States, re siding in London, f England, have ,inventedv 111g? mechanism. Fig. 16, fis a part sectional Fig. is a plan of certain partsfof an alternative form offoldingmechanism'. Fig. 18. is a front view of 'the feed mechanism and container'for the paper with certain parts omitted. Fig. 1 9', is aside elevation n or former 4. The plungerd receives motion from #a toothed wheel 5 mounted yupon a shaft 6 supported in bearings formed upon Yor attached to a suitable baseplate arranged .motion from' a shaft 7 operated by means of a pulley from some suitable source of power, .the motion of shaft 7 being transmitted to shaft 6 through pinions 5 and 61 secured to tlierespective shafts 6 and 7. n

, In drderthat the operation ofthe plunger may be automatically checked in the event of there lbeing-any material increase in thev thickness .of the paper operated upon, for

example should the feed mechanism'presenttwo blanks instead of one `tothe plunger. I

provide an arrangement whereby the thickness of the'. material willv act toV hold the plunger back. ,By this means any damage lrhat might .be caused by the forcing of the thicker material through the `machine 4is avoided. result. I employ a means of operation for the plunger, and of 'such' a nature that thesaid plunger is free thereof for a certain portion of its st-reke, such portion of the stroke being due wholly or partly ,to vits own weight. The plunger after its movement above referred. to is accomplished, is rengaged by its operating means and thereafter'for the rest of one cycle of opera- 'tions is positively'dr-iven.

Inpractice the free travel of the plunger is arranged to takeplace at that portion of its movement during which the paper or other blank is placed in position and the rplunger commences'y its operation thereon.

In .the present instance I, employa lazy-tongs 8,Figs. 1 `and '6, ixed at one end to the rod plan Of .the alternative folding-mechanism.'

Arranged at one k. of\the points of intersection of the cross members of the lazytongs -is a pin 9 upon which is mounted a roller 10. ,'The roller projects into the path of a cam 11 mounted upon the shaft 6, and which cam is formed in two parts, of which parts one, 11a, only surro-unds the body of' the cam 11 for a certain distance so that between the respect-ive outer surfaces of the cam 1 1 and the part 11a there'is formed a cam race which engages the roller during a certain point .of the cams rotation, the said roller-A at theother times being free of the cam'so that in the eventyofithelpaper of-v -fering-too -great a re'sistance the plunger will be held back and the-cam will continue its l rotation without acting upon said plunger,

and as will be hereafter described the paper feed will also be stopped.Y .Secured inany convenient manner to the front'of frame 1 are

brackets

12, 13 which brackets at their inner ends are provided with depending

members

14 and 15 to which are securedthe various members forv eecting the folding of the paper `or other material to form vthe pocketl The brackets-12 and 13, between the vertical faces of which a spaeeor slot i's left equal to the thickness of tlepocket, areeach provided at their upper end with horizontal members upon the uper surface of which the paper to whic adhesive has pre-. viouslyv been applied bythe meanshereafter described, is placed in a `position ready for the operation of the former4'WThe former 4 is of an outline corresponding to the cross sectional outline of the pocket, and in .order to prevent the formation of a vacuum 1n the end .of the pocket as the former is withdrawn, provision is made for the passage of air throughthe former tojthis point. In order to prevent the format-ion o f projections due to' the thickness of paper or the like at this point, the lower end of the plun- -ger at `the'side is recessed as shown at 411,

Figs. 1 and 13. Pivotally supported upon, the member 15 of bracket 13 areplates 151, curved as' lshown at their lower end, which Q'plates are arranged upon each sidevof the former, see Figs. l, 10, 11 and 13, and arel adapted to move into -a position such that theylie one upon each side o f said former as shown by dottedlines in Fig. 1. The plates are normally held clear of the former .by means of a weight 16 supported upon a 'pin attache/d to the body17 by which plates 151 are supported upon their pivot. The

bottom of the pocket.

plates 151 are provided at their lower ends By means of the arrangement just lde-l scribed, as the plunger or former 4.descends the paper is first turned upward against the sides of the'former, and as it is carried down, the end of the former with the paper thereon comes into Contact with the extensions 19 upon the hinged members 18 of plates 151. The plates 151 ontheir initial movement e'ngage the lower ends of the projecting sides of the paper, andas 'theycontinue to-inove into the vertical position L tuck or. fold is formed at this point, which tuck or fold is indicated by w1 in Fig. 4, and is disposed within the opening 15b at the lower end of the plate 151, Fig. 13, said opening being ar-v ranged, between plates 151 and the horizontal yielding plates-'18, which plates 18 serve to support the fold during the operation referred to, and also to support the The spring 2O connectedto the said hingedlembers is of sufcient strength to both-maintain the members in their horizontal position against the downward thrust of the plunger 4, and.

against the effort requiredtocause the inner Vertical edges, of the plates 151 to act upon the paper and form the longitudinal folds upon one side of the pocket. The spring 20 when the front vertical edges of the plates 151 are in alinement with the surface of one side of the former 4, at which period the inner face of the body 17 is in the' vertical plane, and pressing flat against the back of the bracket 15 will be overcome by the downward pressure of 'the plunger, and the members 18, and theextension thereon, willbe turned into the vertical plane, the extensions 19 thereafter acting to turn the projecting portion at the vsides of the bottom of the pocket upward against the' sides of the pluner 4. g The counterweight 16 is of suicient bulk to cause plates 15 to return to their normal position after the plates 18 have completed their work. Before the bottom plates start toyield they bear the pressure of the plunger at a poi-nt close to their hinged center. and as the plunger continues its downward movement and the plates yield, their point of contact with the'said plunger recedes from their hinged center, and therefore the leverage of the spring 2O gets weaker and weaker until after the bottom. fold is produced and only the inner edges of the bottom plates are in'eontact with the sides of '10 pocket 'bein'gprodu'ced ,within'a short stroke of the plunger because any undue obtrusion -f of the vmechanism `'for forming the first folds would prevent the last fold beingproduced. in the pocket beforethe latter were entirely 15 clear of's'uch obtrusion. The two stages in the formation of the pocket just referred to are'shown inFig's. 3 and 4 where a? yindi- `cates the paper which in'Fig. 3 is shown as simply folded/wit-hthe front i/ and back-e 2e of the pocket at aright angle to the bottom W, and; in Fig. 4 the first longitudinal fold at thewside ofthe pocket is formed, and the tuck lmade at the bottom of the said pocket.

i Secured in any convenient manner toi the sides of Athe vertical member' 14 of the bracket-12 are plates 21, Figs. 1, '10 and 11, the edges of which are curved as'shown in the drawings, said ,plates in addition to their peripheral outline also having'aportion of 3o their length turned or bent'ihward so that they engage the projecting portions of the pocket and turn or Vbend same `over andinward against the sides of the former 4 and outsidethe aforementioned longitudinal folds already formed upon the sides ofthe pocket. The folding in the manner just re ferred to completes the formation of the pocket which then present's the appearance shown in Fig. 2. The further movement of 'the plunger or former 4 carries theV pocket down into a. heating device' orI chamber formed sides of

brackets

12 and 13 so as to'close thev space or slot between the verticalmembers,

and which may be heated in any convenient manneimby a suitable device such for instance as anl electric resistance, Bunsen burner, or any other convenientmeans, and 4which in 4the present instance isindicated generally -lo'y a, and is provided with rigid walls. I may, however, retain such walls by means of 'spring pressure so 'that they will yield to any inequalities or differences in the thickness of the paper. The pockets in the passage to the heaterl are acted upon by means of rollers 22 which .are supported-in the frames 23 pivotally mounted upon the

vertical members

14 and 15 of the

brackets

12 and 13. The rollers act upon the side folds of y,the-pocket, and serve to secure the propen adhesion of the gum provided upon said sides to secure them together. v` The j pocket is removed from `the former4 -upon the return movement of same, and the re- '65 moval is effected by'means o-f thes'prings .by plates 14 and 1.5 secured to the.

,524,-FigsL "'11 and 13 lwhich arefseeured tothe

members

14 and 15 and project through apertures therein so that theirlo'wer ends will engage the upper end of the pocket and as 'pockets are heldl and remain in the heater a until the next descentof the plunger. order that the expulsion vof the pockets may be insured, I provide spring members 25 which are shown by dotted linesvin Fig. 13, and which act upon the pocket when it is reandbuclele'- sameso that 'its upperend is somewhat distorted and there'is no chance -of the neXt1-pocket' being thrust into the 'pocket previously removed from the former. Obviously the length of the heating de- `'vice a' may be varied as desired, and it may be of such length as to retain two or more 'pockets jbcfore they are. thrust out.4 Inthe latter case anendless band may besubsti- Atuted -under the aforesaidplates'to aidthe progress of the empty pockets through the 'drying chamber. 'i

-As aforesaid range the apparatus in a manner such that I may simultaneously produce a shell with a pocketthereijn. In order thatv this v'may be accomplished, I duplicate the folding mechanism for the front, back and sides of the pocket, the arrangement being such that the partly folded pocket is .brought into contactI with the paper forming the outer ca sc o-r shell, and the two are thereafter simultaneouslyI acted upon and the shell and pocket formed at one operation. the said shell and pocket being discharged with the placed in the pocket and the poc-liet closed.

carried out by an exaetduplication of the slot and pivotally mounted plates 15"ivith their accompanying hinged pieces 18 and projections 19. In practice. however., where apreviously cut out stiff blank, (see Fig. y5) .is used as'aninner pocket in lieu of a paper sheet, and where a simple overlapping ofthe cutiiaps 1a` and 2 would occur in .lieu -of folds or'tucks as previously described, I may find. it more convenient tov simplify the folding mechanism for the inand- 17 ,the simplified inner pocket folding` mechanism being' arranged to cooperate `with the pocket folding mechanism previously described, thelatter in 'this case, however, forming the outer shell. e

In th'e figures` just referred to, it will be seen that at a point above the level of the. vfolding mechanism before described as act- -ing upon the pocket, I provide a bracket 2f) which is bolted or otherwise securedI to one of.4 the vertical members of frame 1.v The bracket 26` is of U-shaped outline and pirotally supported thereon is a body 27 which the. plunger 4 moves upward, the y saidI The arrangementjust referred to may be' In Y moved from the plunger to slightly compress I pocket open so that the contents may be j ner pocket as illustrated in '18, 15. 1G 'i l is also of U-shaped outline, its transverse member 27@l being normally containedV within a recess 26aL upon the upper'surface of bracket 26 in Figs. 15 and 4 16. vThe upper surface of the bracket 26 in conjunction with an yarm 28 forms a support for the Y paper fr: from which the pocket is formed.

The yarm 28 is disposed upon thefopposite side of the plunger or1.former 4 to the bracket 26, and upon the same side of Vthe plunger 4 as that upon which the plates 151 are arranged. The arm 28 serves in conjunction with the inner edge of thebracket 26 to effect the transverse folds in the blank whereby the back and front of the pocket'.are produced.

body 27 is a nose piece 27C, whichis normally disposed in a position such as illustrated in

F igs.l

13, 16 and 17 when it is in thejpath of the plunger or former 4, and

which plunger as it moves downward carries the paper w with it and engaging the nose piece acts thereon and causes the pivot 27.b to turn, and thebody 27 to be brought into the position shown in 'dotted lines in into contactwith the sides of the blank, and turn same inward against the sides of fthe former. the line of movement. of the plunger A4 are Fig. 15 when the-transverse member 27a is invl contact with the upturned side of the paper 'sa During the movement aforesaid, theside members of the body 27- are brought Arranged upon each side of fixed members 29 which: accomplish the bottom folds of .the inner pocket, The fixed members 29 and the nose piece 2,7c replace respectively the hinged pieces 18 and their projections' 19 previously described. The

members 29 form partof brackets 30 which arey secured by means of screws 31 to the side Vmembers of the bracket 26. The blank m1 for forming the outer shell is placed upon the upper surface of the

brackets

12 and 13,

and after the folding of the inner pocket in the manner just described, the plunger 4 with the partly folded pocket thereon comes into contact with the paper m1' which it turns or folds upward as indicated in Fig. 7 by forcing it betweenthe inner ends of

xLie brackets

12 and 13.

The continued movement of the plunger 4 causes the side of the paper m1 to be folded "inthe manner already described in connection with the pocket', but in this 'casethe forming of the first longitudinal fold in theouter shell simultaneously edects the formationI ofthe second longitudinal fold in the pocket, theplates 151 being disposed upon' the opposite side of theformer 4 to thatupon which the body 27 is placed. This operation completes the formation of the pocket, the plates 151 and 138, and the plates 21 operating in the manner before stated serve to complete thenfolding of the outer Secured in any con-v `yenient manner to the pivot 27b of the vof the material' in use.

shell. It will be understood that where a shell is employed, the inner pocket is provided with a flap designed to be turned in and tucked .between the front of the outer shell and the'front of the pocket so that the ends of the contents vof said pocket are protected. As in the case of the pocket, such portions ofthe shell to which it is necessary that adhesive be applied have such adhesive appliedthereto by any suitable means prior lto their presentation to the machine.

The feeding mechanism to which reference has already been made,'and which is illustrated in Figs. 1, 6, 12, 14, 1S, to 22 comprises a suitable magazine which is arranged .upon one side of the plunger, the blanks when removed therefrom being received by a tray al carried by a pair of swinging arms b. -The construction and operation of these parts will be hereafter more fully described. The magazine in addition to applying the necessary adhesive tothe material presents-- certain'novel features whereby the upward movement of the support for the papers is controlled by the height of the said papers.

.The'feed apparatus also presents the .novel feature that the `gum applying members automatically adjust themselves to the width The ma azine is o-pen on one side so that the ready introduction of the blanks is permitted, which blanks when in the magazine are held against lateral displacement by a gate arrangement as shown, or other means which may be caused to press against the sides of the blanks. The

,gate just referred to is arranged so that it i Fig. 18. The half nut 33 engages a screw thread upon a rod 351 supported at each end .in suitable bearings, and which rod, as will be presently more fully explained, is hollow. i

The screw threaded hollow rod receives lintermittent motion from a ratchet wheel 36 `secured thereon, and with which engages a pawl 37 carried upon an arm 38, which arm receives arocking motion as shown from the lazy tongs of the 1nachine,--by means of the rod 9a, Fig. 1, connected to a lever 9b pivoted at 9c on the frame 1z By arranging for the operation of the feed mechanism from the lazy tongs 8- it is'evident that the checking of the movement of the plunger 4 will also stop the feeding of the blanks. Arranged between the operating-arm for the pawl just referred to, and the said p awl, is a resilient plate 39, Fig. 18, oneend of which is provided with a piece of leather or any other material designed to come into contact with a surface upon an extension 40 of the pawl 37. The pawl 37 is. spring pressed into engagement with the ratchet, and normaily the friction surface upon the spring member vis clear of the pawl. At certain periods, however, as will be hereafter explained, the friction surface comes into contact withl the surface on the pawl, and at such time the pawl is held out of engagement with the ratchet,

and no upward movement of the plate supporting the blanks takes place. The action l just described is effected by means of a wire 41 or other flexible connection Figs. 12 and 18 attached at one end to the spring member 39, and at the other attached to a. radially moving arm 42, Figs. 12 and 14-connected at one end by the slot 43 to 'a pin 44 on a member 45 carrying rollers 46 whereby the feed of the blanks from the magazineis effected. The arm is so constructed and arrangedthat itis capable of a certain amountof movement transversely of its length. Means are' provided for adjust-inv the effective length of the wire 41. It will be readily understood that when the upper-most blank is at a certain level the rollers 46 pressed thereon will lift the arm 42' pulling the wire 41 and lift? ingthe spring member 39 so that there is contact between the leather thereon and the surface o f the extension 40 on the pawl 37. When this takes place the feed pawl is thrown outof action as -before stated. j

The mechanism whereby the blanks are removed from the magazine comprises a bar or other body 45 receiving reciprocal motion through arm 46a by means of a rod 46b passing through the aforesaid hollow screwed rod-35., s eejFigs. 1, 14 and 18 and attached as shown to the rocking arm38 carrying the feed pawl 37, and having at its upper end an adjustable arm 47 provided with a projection 48 engaging a slot in the said arm 46a operatively associated with the aforesaid bar or body by means of the slotted end thereon which engages a pin 50 sho wn in dotted lines `in Fig. 12, and in full in Fig. 18. The bar Aor other body 45 moves in suitable guides 51, and carries supports for rollers 46 which rest upon thef'upper surface of the 4uppermost blank m in the magazine. The rollers 46 just referred to are preferably provided l with a roughened surface which. may `comprise a number of small stud-like projections thereon, and they' are so arranged that during the inoperative portion ofthe movement of thebody to which they are attached,

they are free to rotate. 'This action is secured b v providing the rollers at their spindles with a ratchet wheel 53 with which en.- gages a pawl 54 as shown in Figs. 14 and 18.

pon the opposite movement of the body 45 taking place, the rollers are fixed and oper# ate to push the blank out of the magazine.

'The gumming shoes'53a are supplied by tubes 54a connected in any convenient manner with a gum receptacle 55,--and which tubes ,541jl are capableof radial move-ment in both the horizontal and vertical planes. T he movement -in the planes just referred tov is controlled on one hand .by means of springs 56 coiledV aboutthe pivots of the radially moving rods 57 carrying the tubes 54a tocause them `to bear upc-n the surface p of the blanks with the desired amount of pressure, and on lthe other lia-nd the tubes are acted upon to cause Vthem to travel toward the edge of the paper, by means of springs 58 acting upon arms 581 connected to thep'ivots of the rods 57. The outward movement of ,the rods however, is controlledby means of shields 59", 59 attached tothe `spindle of

rollers

59, 59a, the purpose of which will'presently be explained. The ends of the tubesjust referred to are provided with swivel-ed shoes as shown or the like 53 presenting a sufficient surface to cause the tubes to adjustthemselvesto the angle of the 'surface' upon which they'rest.` By this means the properapplication of the adhesive is insured in the event yof the buckling or curving of the blank.

` The

rollers

59, 59 just referred to are arranged one on each side of the top'of the Imagazine, and said rollers are arranged so that their axes are in, or substantially in the plane of the uppermost blank. One of the rollers isiixed while theother is mounted.V upon a member,62 free to move laterally under spring pressure so that it may automatically ladjust itself to the width .of the blanks against the sides of which the rollers bear. The roller is supported at the upper end of a rod 63 carried by arms 64 arranged to swing in the horizontal plane by means of a pivot 64a to which .one end of the arms is attached.' In order that the feeding of more than one blank may be avoided in the case of a variation in the widths of'the blanks, the surface of the rollers, which are covered with rubber or other suitable elastic. material, are-provided with small projections arranged upon lines inclined to the line of vtheir axes. The-blanks when removed from themagazine are fed by continually rotating rollers G5 to the packet 'machine Such rollers may be driven by a belt 66. Fig. 6 from a pulley G7 on the shaft 7 of the packet making machine. The blanks when fed by the rollers 65 are received. in the aforesaid tray a.

Instead of employing rollers having surfaces such as those before referred to, I may employ, hair wire, or other bristles in place of the rubber or 'the like. said bristlesbeing preferably arranged so that they are inclined relatively to the 'longitudinal axis of the roller.

.The traya as already statedis attached to the lower ends of the arms b, which arms are disposed upon each side of the frame l vas shown in Figs. l, 6 and 19. The arms are connected by a U shaped member b1 arranged behind the frame l. The arms l) are secured to a pivotj b2 carried in'bearo ings,`and the bearing has attached to it a projection b3 to which is attachedl one end of a spring b4, the other end ofthe spring being ,attached to the aforesaid U shaped member b1. The tendency of the spring b4 is to pull the arms sharply inward,the outward movement of the arms b being eifected' by means of the projection c attached to the upper end' of the rod w attached to the lazy tongs 8. The tray is cut away or otherwise shaped to permit the passage of the plunger and at one end it is provided with an abutment a which is shown as being Xed, but which in practice willpreferably be an adjustable member so that the position of the '25 blanks may be properly. adjusted with regard to the former il. The tray mayvalsgL have its side members capable of adjustment to 'suitblanks of di'erent widths. The operating member or projection 0 before referred to has coperating with it a body g pivotally mounted uponA the rod w, and which bod-y is of wedge shaped outline and is yeldably held by lmeans of a spring al, Fig. l with its outer surface flush with the '35 outer surface of the body to which it is' attached during the downward movement of the rod. A roller'al1 travels over the inner surface of-body c, said roller being carried by the U shaped member b1. As the wedge 40 shaped body is pivotally mounted as aforesaid, the roller presses the upper end out-- ward and passes on to the outer'surface of \rod w, pulling arms b outward to receive j the blank. On the return movement of the rod w, the roller travels on the outside of the wedge shaped body, its passage over the end of the wedge shaped body producing a sharp inward movement to'bring the tray,

and with it theblank, beneath the plunger.

The. swinging arms during this movement operate'against the spring b4. lThe tension ofthe spring b4 effects the sharp inward movement above referred to.

, The machine may be readily adapted for makingv packets ofvarious sizes by simply varying the widths of the rod and the angle brackets, or the width between the folders,

rollers and plates, the folding parts being mechanically self-acting, or independent and 6l) self-contained. It will also be seen that the principle upon which the sheets are gummed and folded permits of making a double pocket consistingof an outer wrapper and an inner lining. 'The gummed "edges of the bottom sheet would adhere tothe top sheet and the same gummed edges of the top sheet would adhere to the outer edges of the bottom sheet when the pocket is made up. l may also double the production 'of my machine by duplicating the brackets, 12, 13,A

which may be placed at each end of a plunger so that a pocket may be made at both right and left strokeof the plunger. Obviously where the machine is arranged to produce at one operation an inner slide and an outer shell,the magazine and the swinging arms with the tray presenting the blanks to the former would be duplicated. In order to check the impetus of the swinging arms b1, I ,may provide the frame l with resilient members Bas shown in Figs. QOaud 2l, said members B being placed upon each side of the frame, and being expanded by a V shaped projection on the rod w as shown. By this means any recoil which might take place through a too violent contact of the arms with the leather or other buifer E is prevented.
