Speciiication forming part of Letters Patent No. 12,51 l, dated March 13. 1855.

nails',tacks,spice, dac.; and I dol hereby declare that the following is afull, clear,v and Y exact descriptionofthe constructionv and opi eration of the same, referencekbeing -had to the annexed drawings, making part of this specification, in which- Figure'l is a longitudinal side elevation,`

Fig. 2 is a top view, Fig. 3 a front view and part section at the 'line III and II," and Fig. 4. a back end View, of the machine.

The nature of my invention'yconsists in an .arrangementfof rollers tol bring-the paper from an endless roll along the machine to the place where the box is to be m,a de seondly, in astamporknite frame by which the paper is cut into the lrequired shape necessary for" folding; thirdly, in a pasting-frame provided with suitable paste-boxes so arranged. as to paste those parts of the paper necessary to be pasted; fo urthly, in a wheel provided with arms` to Vwhich molds are attached, around which' the boxes are to be made; itthly, in an arrangement of slides by which the paper is folded `around the mold,land,' sixthly, in a 'pairlot pinchers to draw off the box from the inold after completion. These different parts are made to move successively partly together and partly one after the other, said motions being produced by anarrangement of levers. actuated by cams or toes fast upon shafts and working in such a manner that by one revolution of said shafts' always one box will be completed. i

A A 4are themain frames of t-he machine.

BB are the driving-shafts, geared together by ,the wheels w wf, and. upon oneotsaid` shafts eitherpulleys arefto be placed to drive the machine by power or (as'h'ere represented in Fig. atlacrank C is attached to move the same by hand. y4 j D D' are rollers running in bearings in the frames A iA. These rollers are of such a size that the outside circumference of the. same is equalto the length of thc paper required for one box. The lower rollers .D have' cranks ff attached to the ends of their shafts, which are connected together by rods c e', thereby connectingal'l t-he lower rollers together, so that the same move always simultaneously together.. The upper rollers ` loose in the bearings inthe frames AA `and obtain their motion frointheir corresponding lower4 rollers by friction. I i

Near the front of the machine and as close as possible to theplace where the box is made are situated two sm aller rollers d d', moved by gearing v virom the nearest'roller D. l By, this arrangement the paper is always heldl fast until the operation of folding begins.

, E is a stamp or knife frame situatedbetween two rollers near the. after end, guided` in the frames A A", and connected by links' e e to the beams F F', from which the same I To the lower side of this frame E stamps or knives Areceives an up-andedown mot-ioni,

are attached, (shown in Fig. 2 in dotted lines) fitting, when pressed down, in suitable disks, by which said stamps or knives .the paper is cut or punched 'out the required shape inr4 the downward motion.l Forward of the frame E, and likewise between two` rollers, the pasting-frame G is situated, guided, in

the frames A A', and connectedby links g` gio the beams F F', from which the saine receives an upand-down motion.` This pastingframe has suitable openings a a to contain boxes filled with paste. The lower sides of ,those boxes are covered with wire, flannel, lsponge, or its equivalent, so as to allow the paste to go-through in small quantities only, which by pressing .down upon the paper is communicated tothe latter.

H isa wheel with four arms having at their extremities the molds hat'tached, round which the boxes are to be made., This wheel is Ifast h h h 7L are pins `attached 'to the wheel 7L, forming t'he` inner molds for 'the bases, fit

' between projections K IK', att-ached to the insidey of ,the frames A Af, and whiclrsaid projections/form ish/esides of the outer mold.

`lis ,a hinge-valve attached to the projeclattached to it to keep it closed, and is likewise secured by the `catch L, fastened to the to a shaft running in bearings inthe frames if closedtowns the bottom of projection K'. .A spring la, acting against the `back of the catch L, keeps the same in'this position.

lns'tead of the weight d', attached to the valve l, a spring may be used for the/same purpose. y

M M are the top slides. N N' are thesidc slides. O is the lower slide, and O the upper slide, by which said slides the ends of the paper are folded around the mold 7l. These slides are guided insnitable guides.

P are pinchers situated under the center of motion of the whecl'II and sliding up and down oversurfaces Q Q', attached to thcframes A A. Between t-he lower extremities of thc pinehers a spring 7c' is fixed to force the same apart atthe required time.V On the upper end ofthe pinehers are projections pp', which slide over the surfaces Q Q'. Those surfaces Q Q have elevations part of the way, and so situ-Y ated that said pinchers P will be thereby pressed together in their downward motion, while at both extremities the same will be forced apart by the action of their spring la. The reason of this arrangement is to ,give

clearance at the upper position for the mold h, with the finished paperbox'attached, to-

pass between the same, to keepthe paper box tight when" the same is to be pulled olby the pinchers P from the mold 71. in the downward niotion of the pinchers, and to allow thebox to fall freely away from and ont of the pinchers Pafter having been .pulled oit from. the.

"F F are beams fast to a shaft b, turning in bearings in the frames A A'. To theforward end .'of those beams the upper slide O is attached,-as well as the stamp or knife frame E and the pasting-frame G, as has' been before described. These beams F F are connected, through the rods n n', 'with levers R R', turning upon centers'r 1r', fast to the frames A A', andv said levers 'R R are again con-f netzteil with levers S S', turning upon centers s s and which latter levers are acted upon by earns or toes 1 'and 2, fast ion .the drivingshafts B B.- Through this connection motion communicated by the toes 1 and 2 to the levers S S' is communicated to the. beams F F', and consequently to thestam p or knife frame `E, the pasting-frame G, and the upper slide 0', giving thereby an up-anddown motion'to those parts.

T T' arelevers` turning on centers tif', fasti,l

on the frames A A', and connectedgthrough the rods m m', with the cranks on oneot'thel rollers D, by which. connection a rectilinear motion,communicated to the levels T T', is,

converted into a circular motion of the :roll` c rs. These levers T T" are actuated bythe camsfortoes l3,1, 5,6,and 7., fas't on .the shafts -ll-, 'whichsaid cams ortoes are so' arranged kthat the motion communicated'by the salue. to .the one. cud offthelovers 'IT-T shall exactly produceon-o whole revolution of the rollers. vU is alever turning uponithe shaft '(lhfast ver is attached to the lower slide O and the other end is actuated by the cams or tocs'8.

.and 12 13, fast to the shafts'B l', and the other cnds of said levers are attached to belll cranks W \V', turningon centers 1' if', 'fast to the frames A Al,'and connected with the lside slides N N', respectively. By this connection the action of' the cams 10 11 and 1f. 13 upon the ends of the levers V V' produces a lat?- eral motion to'ithe slides N N.

X X' are levers turning upon-the shaft C, fast to .the frames A A. he one end of these levers is actuated by the cams or toes 1415 and 16 17, fast tothe shafts "B 13', and the other ends of said levers are attached to bell- -cranks Y Y', turning en centers i i', fast to the frames A A', and connected with the top slides M" M', respectively. By this connection the action of the cams or toes 1 4 15 and 16 17 upon the ends of Ythe levers X X produces a lateral motion to the top slides M M.A

Z is a lever turningnpon the shaft q, fast to the frames A A'. 'lhe one end of this lever is attached, through the links 6', with the pinchers P, and the other end isactedonbya cam 18, fast on the shaft B. This cam 18 is sooonstrueted that by itsv action upon the lever Z the pine-hers P will 'be pulled down and retained for a certain time in thatposition, after which time and as soon as/the cani 18 sets the lever Z at liberty the pinchers P will be forced up again'by a springz, attached tothe lever Z.

L' is a rod ru nningncarl y the whole length of the machine under the rollers. The for- Ward 'end of the same is ent` out for -the pins 71,' of the wheel II to t in and is pressed against said pins, by the spring o, acting against the underside of saidrod L'. -The same has vsuitable. guides at the forward end and is attached 'by means of a spiral spring q.' at the after end to the frame A. On one side of t-hisrod L and near the forward end4 is'a small projection Fig. 3,'so situated as to operate when in motion, upon the catch L in such a 'manner as to liberate the hinge-valve I from its action. P' is aleve *turning upon a fixed centerg,

fastto theframe'A.l 'lhe oneend of this lever actuated by the cam 1,9, fast on the shaft li.'

.By this connectionof the lever P with the ,rodjL'thc motion communicated to t-he lever 'P' bythe cam-1D produces a forward motion of the rod L,.and.tnrns thereby the wheel Il as soouas' said -rod L' comes in contact with oneA ofthe pins h', fast to the wheel ll. The cam 19 has two projections, which are so con structedl that the Vtirst projection moves the 'lever P. acertain distance and retai'ns'itin,44

about forty-fivel degrees.

thatposit'ion some length `of time, when the second projection begins to act, moving the lever P some distance farther, and likewise retains the same in that position a certain vlength of time and then leaves the lever P'l `pulls` the rod L', as well'as the lever P', back again to itsformer and original position.

Instead of cutting or punching out the paper by the iabove-described flat stamps the same may likewise bedone by attaching the knives to oue of the rollers D or D', andA the pasting-frame `may likewise be changed by substituting 'a ihollow roller with suitable openings, and into which the paste is forced.A

The spacell between the frames A and A' `and the lower rollers D is filled Ain with plates H', whose upper surfaces come very nearly even with theupperpart of the circumference of thev rollers D, 'forming thereby a table over 'which the paper slides. l,

The operation of this machine is as follows: ln the accompanying drawings the' machine `.is represented in a-'position supposed that a box has just been completed. The cam 19 has already moved a little the lever P', and

consequently the rod L', and as this motion hasbeen just suicient for the projectionaV i Vou the latter to have acted on the catch L, so

as to bring4 the same clear of the valve l, saidl valve I is now only kept closed by its. weight a', and can be pressed open by the mold h to allow'the sameby the mot-ion of the wheel H to move out of'the'outermold. `By turning now at the handle G, setting thereby'themachine in motion, the cam 19 will still act upon the lever P', and consequently on-the rod -Lf, which comes now in contact with one of the' pins h' of `the wheel H and turns `the same partly; around, 'thereby bringing the inner mold h. (where we suppose a nished box attached) clean of the outer mold, formed by the projections K and Kand the valve I. VIn this'operation the valve I has been pressed downlto allow the mold h topass, and is then closedagain by its weight a', and the catch' L, which has likewise been released ,from theprojection x of the rod L', is pressed by its spring k, so ya-,"to lock the valve I lirnily to its place. The cam 19 moves the lever P', and consequently the rod L', so far that by the action of the latter against the piu 7L' of the wheel Il this wheel H' has turned so far around that its arms stand atY an angle of During. this time the cam 18 has acted continually on the leverr i Z, keeping the same, and consequently the pinchers P, steady and the latter inthe lowerV position. As soon as the arms of the wheel- Harrve at the above-described position-4 namely, at anangle` ofy about forty-tiverdegrecs-the cam 18 relieves the lever Z from its action, and tliesame is no'w acted upon 4by vvthe spring z, thereby forcing the pinch' ers `P. suddenly upward. The pinchers are at this'top position ,pressed apart by the action of their spring 7c', as above described, so. as to allow the arms or Imolds h of the wheel H to pass within them. At the same ,tixne the above-mentioned operation has \been going on the toes 8, 4, 5,.6,`and 7 have acted alternately upon the levers T and T', respectively, moving the same backward and forwardl, 'and whichy motion has been commnn-icate, through the rods fm mi', to the cranks ff' of one of the lower rollers D, prothe same, and as all 'the lower rollers are connected ogether, and the circumference of each 'roller is just equal to the length of pa@ of'papeil has by this operation been brought forward! As .will appearby the following, there isin the table of the machine, formed by thep` ates H' and in the positionthe ma-y .lying close to the forward en d of the machine, ready cut and pasted for folding; close to and cut or stamped out, only requiring to be the `paper drawn into the machine by the situated behind the machine. By the operareadycut andipasted, isbrought now forward and pushed over the opening of the outer mold, resting upon the top slides M and M', ready tobe folded, While the second piece of paper is brought forward and into the place which was occupied before by the first piece, to be pasted by the next operation, and a further piece from the endless roll of paper is pulled before by the second piece, to .be cut olf by the stamp the required length and shape. The first projection of the cam 19 has rought the arms of the wheel Hin the position above mentioned and kept the same statidnary in Vthat position until the motion of the rollers, and consequently ot the paper, is completed.

upon the lever. P', and consequently on the rod L-, producing a further motioni of the wheel H suicient to bring the arm oilrinner l'mold h into the outer mold,l, thereby;folding of said outer mold around itself and taking it with it intov the same, leaving onlythose parts of the paper projecting which are to form `the top andnend of the box. This cam 19 keeps, tthen, the lever P', and consequently the rod' L' andfwheel H, for some little time stationary in that position-until one of the top slides the same is secured, when the cam 19 leaves the lever P', and the spring q' at the end of to itis original position :ready for the next ac'- tioul "".After the mold h hasvbeen moved dncilng thereby j ust one whole revolution of per required to' make one box, such a length chine ist ow in,.one required length of paper,

K K andA the Valve I the' toe Meets then upon the lever X, which lever by its connection, through the be1l-crank Y, with thetop slide M moves the latter over the moldv h,

.folding thereby the projecting paper over the The toe l5 acts now uponl ythe same will likewise be pasted together.y

.The toe l2 acts now upon the lever V', which by its connection, through the bell-crank XV", with the side slide Nfmoves the latter over the end of the mold h, folding thereby the projecting pieceof paper over the same. The tool?) acts then upon the opposite side of the `lever V', and brings thereby the side slide Nl away' again. W'hen the side slide N is about half-way brought back again, the toe 9 acts upon the lever 'U, which by its connection with the lower'slide O brings the same upward and over the end of the mold @and at the same time thletoes l act upon the levers'S and S', which by their 'connect-ions, throughthe levers R and R and the rods 'n and n', re spectively, with thev beams F and Ff, and the connection of the latter with the upper'slide 0'-, move this upper slide downward and over the end lof the mold h. By those two last op- @rations the top and bottom projecting pieces of paper have been folded over the end' of the ino'ldhand over the piece of paper which was folded before by the side slide N. The ,toes 2 act then upon the opposite sides of the levers Sand S- and the toe 8 upon the oppositeside ot the lever U, bringing thereby the upper and lower slides Ol and O back` again. During the return motion of --those slides the toe 1Q acts upon the lever V, which byits connection, through the bell-crank W, with the side' slide N moves said sideslide over the end ofthe mold h, thereby folding the paper projecting ou that side over the end of the mold and likewise over the three other pieces which have been' folded before over 'the end of the mold 71 and .as this last-folded piecev o f paper was pasted beforehand the same has by the lastmentioned operation of folding beenpasted to the other pieces of paper which were folded' first, The toe 11 acts then upon the opposite side of the lever'V, bringing thereby the slide' N back again, and the toe 17. acts upon the lever X', whereby the top slide M is broughtv back, and leaving the boxjnished, folded,j and pasted together on the .mold h'. During the time thatthis operation 'offolding thegpaperal'ouudthe mold h has been goingt'onithe cam 18 has acted on the lever Z, and, through the connection-of the latter with the pinchers P, the same have been pulled downward by the action of this cam 318 on said lever Z. In this downward motion of the pinehers P the projections p pf on the pinohe'rs P have passed over the elevations on the slides Q Q", and have pressed thereby' the pine-hers P together, s o that the same take hold of the iinished paper box, which We have supposed to be on the lower mold h,andpull thereby said box off this mold h. As soon as the pinehers have been sufficiently far moved downward, so as to have pulled vo the paper box clear `of the mold, the projections p p"leave the elevations on the slides Q Q, and the pinchers are then forced apart by the action of their springk',thereby allowing the boxY to fall out from between said pinchers. .During the down ward motion of the beams F F' the knife or stamp frame E and the pasting-frame G have been pressed down and upon the paper sit'- nated upon the ltable H and between the rollers D and D' and held stationary at that moment'by said rollers. By this action the stamps or knives attached to the under side of the frame Ecut ofia piece of paper the required shape necessary forv one box, while the boxes with paste, situated within the past ing-frame G, have (by being pressed upon the paper) pasted that piece'of paper inthe required places which lies underneathv the same and which was cut out by the former formerlycut-0E piece of paper has been pasted in the required places preparatory for folding the next time.' 'The paper from which the boxes are to, be made' is fed' int'o the machine from an endless roll situated nearthe after 'end of che same, Aand which is prepared beforehand, so as to have exactly the width vrequired for a box, andthe knives or stamps have therefore only to out the ends the proper; shape.vl
