IMPROVEMENTDIN MACHINES FOR MAKING PAPER BOXES.

Specification forming part of lLetters Patent No. S5, 301, dated December 29, 1868.

To allV whom t may concern:

Be it known that we, WILLIAM GATES and DAVID J L LLOYD, both of Frankfort, ,in 'the county of Herkimer and State of -New York, and ASAMUEL MILLER, of South Hammond, in the county of yJefferson and State of New York, havel invented 'a new and Improved Machine for MakingPaper Boxes 5 and we dohereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being hadl to the 'accompanying drawings, forming part of this specifica tion'.

This invention relates to a new and im# proved machine for making paper boxes, such as are "of square'or,rectangularvforinin their transverse section, and is an improvement on a machine for` the same purpose patented by R. L. Hawes, April 24, 1855; and the: object of the present invention is to vobviate several difficulties attending theoperation of the orig- 'inal machine, a practical use of which forY a number-.of years having suggested 'a number of improvements, all of which are hereinafter fully shown and described. i o In the accompanying sheet of drawings, Figurel, Sheet No. 1, is a side elevation of our invention; Fig. 2, an end elevation of the same; Fig". 3, Sheet, No. 2, fa side sectional view of the same, taken in the line wx, Fig. 4 5 Fig. 4, a transverse section of the same, taken inthe liney y, Fig. 3; 'Fig'., Sheet No. 3, a section of a portion ofthe same, taken in the line z z, Fig. 4; Fig. 6, a detached perspective view of certain. parts pertaining to the same; Fig; 7, 'a detached face view of acutter perf taining to the same; Fig. 8,' a section of ay paste-box pertaining to the same, taken in the line zf jz, Fig'. 3; Fig. 9, an enlarged face view of a portion of the paper strip from which the boxes are made, showing how the paste is apf plied; Fig. l0, an enlarged face view of a portion of the same, cut oft' the required length to form abox Fig. 11, a' detached enlarged perl spective view of a paper box.

Similar letters of reference indicate-.the same parts in all the gures.

- A Arepresents the frame ofthe machine, which may be constructed vin any proper manner Vto vsupport the workin g parts, and B represents 'rests upon an elevated portion of the frame A, and in which box there are lsecuredftwo standards, a', tov serve as ,bearingsvv for the kshafts b b", placed one above the other in the same axial plane, and having rollers x on their inner ends, said rollers beingin 'contact with each other when the paper of which the boxes are made is not passing between them. o The lower roller DX of the lower shaft. b is made of wood or other suitable material, which is somewhat absorbent, and this rollerl) X works in and is kept moist by the water in theubox O, and meistens one edge of the strip o f paper as it passes into the machine, said edge being designated Vby c in Figs.- 9 Vand 10,'Sheet No. 3.

The paper strip, being designated by E, and,

.'besides, bein g shown separatelyV in Figs. 9 and l0, is shown in its passage from a continuous 'roll Ainto or through the Amachine in Figsl and 3. This portion" or edge o ofthel paper strip which is thusgmoistened; is" thepart lof which the bottoms of theboxes are made, and

the object oimoistening it is to facilitate the folding and insure `that portion vof the work being performed ina smooth and neat man- F represents a fountain, which is" attached to or rests upon an arm, d, attachedA toy the upper part of the back B. This fountain is elevated above all the working parts ,of the machine, and it supplies,.by means ofthe tubes e o, flexible or otherwise, paste or muoilageto the two paste-boxes G GX?. Y This fountain'may be made of quite large capacity, much larger than the two `paste-boxes combined, asgthe former may be sufficiently elevated 'astobe entirely out of the way, and made of anyconvenient size, whereas thel capacity vofthe paste-boxes is restricted, owing to theirnecessary closer proximity to theworking Apartsbf the machine.. n f i f i By this arrangement, therefore,the pastea boxes may be'kept supplied a longgtimewith paste or mucilage, and the trouble and inconvenience of frequently replenishing the pasteA boxesavoided. l v

'The paste-boxes G GX are placed on the inner end of a lever, B', connected with it, said levers bein g pivoted to the inner side of the plate S, and each having a spiral spring, u, attached to it, which springs have a tendency to keep the jaws q off from the plungers L when the machine is at work, and which effect this end after fiat springs c at the outer ends of the levers B' pass the plate A', said plate A', when adjusted so as to .project over or beyondthe edge of the back B, being in the path of the rotation of the levers B' and springs fu, and the latter Ab eing of sucha length that they will be forced .backward in Aorder to pass underneath plate A', and vth ereby actuate the levers'B, so as to cause the jaws q to project over the plungers L.

By adjusting the plate A' backward, so that it will not p rojectbeyond ,the edge of the back B, and be koutof the path of the rotation of the springs u of the levers B', the jawsql will be rendered inoperative. By this simple adjustment ofthe plateiA" the platens Ware preservedfrom injurygwhen theshaft Nand plates M S are 'rotated for the purpose of removing the plungers from the machine.I

Hitherto the platens W/were very frequently injured .by the jaws g coming in contact with them after the plunger above ithad been removed, no means having beendevised in the originalmachine to render the jaws inopera- .tive when -the machine was not at workand the driving-shaft turned in order to vremove the plungers for the purpose of cleaning, repairing, Stc. j g

The plungersL having been described as having an inward movement y at their rear ends caused by thestationaryhor flxedcam B, Fig. 5, lit is necessary to limit thisinward movement; and this part of `the invention refers to means to effect that endwhich consist of stops w, (see Fig. 4,) which are .simply setscrews inserted in a hub, a', projecting radially from the inner side of the plate l 0'0" 0'." 0"" represent folders which operate against the bottoms `of the boxes, folding the paper s o as to form the boxes.. The folders 0' are pivoted in or to a spur-wheel, D', `on the driving-shaft N, the'outer ends of said foldersthaving each e a spiral spring, b', attached, which springs ,have a tendencyto keep thefolders 0' y in-contac'tlwith the inner side ofthe wheel D', (see Fig.. 4,) said folders being forced out from the wheel D' asv1 they come in contact with'a xture, c', vattached to ther frame of the machine. (See FigA.)

There is onlyone folder 0", and this is at thelower end of a lever, E', which is attached to vthe frame, .and is operated by a spiral spring, d', and projecting pins e' at the outer side of the wheel D'. (See Fig.'2.)

There is also but one folder 0'", and this projects from a tube, j", Figs. 3, 2, and 1, on a shaft in the upper part of the framing, said tube f' having an arm, g', extending from it,

with a roller, h', at its outer end, said roller being made to bear on the periphery of the plate S, which performs the oice of a cam by on thesameshaft'as the tube f',`to which the folder 0"' vis attached, said folder 0"" being in line with or directlyover the-platens W. This folder is raised by an arm, b", having a roller, of, on its ends, which is made to bear upon the periphery of S bymeans of a spiral Spring, dxv F, Figs. 3 and 7', represents abox or case, which is attached to a shaft, 9*, in the framing, and has within it a guard, 0r, Figs. 3 and 7, upon which a spring, H', bears. At the rear of this guardGr' a knife', or cutter, I, is placed, which is Vsecured .in position by av plate, I', and set-screws h'. This guard holds the paper down while being c ut between the cutter I and a cutter, i", which is fsecured by screwsjx to each wall or surface p, the

cutter I having a slight movement whileeff ecting its c ut, in consequenceof. aspiral spring, kf, which is connected to'an upright arm, l', on shaft g", Fig. l, throwing back the cutter after beingraised by the pins e', 2,' of wheel D' coming in contact with an arm, J x, Fig. 1, which extends f'rornthe shaft g'x. The folding-jaws g, Fig. 6, have their pivots von shafts mx, the lowcrends of the jaws resting on bearings n' on the shaft, and having guide-pins 0"'passingvv through them, and the lower ends of the jaws have aspring, 10'., restingl on them. j

The object of these springs is to admit of the folding-jaws rising Ato accommodate them-- selves to the different thicknesses of paper being folded over the plungers, and in case two thicknesses of paper should accidentally pass into the machine.l

K' represents a inishing-roller, which works overthe lapped edges of: the folded paper on the outer side of the plungers as the latter are moved out from the platens or tables W. This roller 4is fittedbetween two spring or elastic arm's,.q' q',','( see Fig..2,) vwhich extend from a shaft, L', in the framing, saidshaft havinglan arm, y', projecting from one end of it, which has a bent lever, M', in contact with it, and this leverA is actuated at the proper time by the pins e' of the, wheel D', soas to throw vthe roller K' in cojntactwith thelapped surface of the. paper on the plungers, the roller smoothingsaid surfaces' ,ai1d giving them a finished appearance. Y rvv 'Ihesprings .or elastic arms q' q' admitr of the roller yielding or giving to anyirregularity of surface over which it may pass. e

'N' represents a slide, which is fitted on `a vertical guide, O', in the framing, and is .a1- lowed .to work freely up and down thereon. This slide has two curved rods, s s', attached to its upper end, and an arm, t', is pivoted to it, which arm extends down and is pivoted at its lower end tol one end of a lever, P', the outer end of the latter being pivoted to an upright rod, Q', the upper end of which is pivoted to jaw q.

:the'lo'wer of two parallel levers, R' It', (see Fig. 1,) said levers being pivoted at one' end to the framing of the machine, as shown at u',

and the opposite ends connected by a bar, 'u'.v

These levershave each an inclined projection,

w', attached to or fitted in. them in any suit; .able wayy against which radial rods w', iitted in or attached to a hub, S', on the shaft N, act, said rods and projections, in` connection .with a. spring, y', connected to lever P', the

levers It' R', and the means by which they are connected to the slide N' giving an up-and` down movement to the slide N', the curved rods s' s' on the top of which, as they descend, insuring the discharge of the nished boxes from the machine.

Having thus describedV the several parts -with more especial freference to those parts which are novel, and comprise the subject matter of `this specification. The endless roll of paper E passes between the rollers 'D D,

`which moisten the edge c, then passes over guide-rollers a* a.X and down between the -rollers J J, where the moistened edge c is pasted, and strips b", which extend transversely across the paper, (see Fig. 9,) the pasted strips b X being at equal distances apart.

-The paper is cut at one edge of each pasted strip b", (see Fig. 10,)which shows the length required for the folding of a boX. The cuts are effected by the cutter I as each cutter i* V`-passes underneath it, the guard G' holding the paper while it is being cut, and preventing the paper being folded back while being cut. The paper, during this cutting process, is between the plungers L and the tables or platens W; and, to facilitate the passage of the plun gers over the paper while the plun gers are being moved forwardunder the action of the levers U and the fixed camsVV, the outer ends of the plungers are raised in consequence of the rear ends of the same coming in coiitact with the xed cam It, as previously alluded to.

After each strip of paperis cut, the plunger directly over it is forced down in consequence of its slide 'I being pressed down by its roller rcoining in contact with the wide portion Y of the rim of the back B, the platen or table W underneath the plunger being, of course, pressed down. The foldingjaw .q Vis then moved in consequence of the spring 'v `of its lever B' coming in contact with the curved plate A', and the folders G"" then fold down the pasted edge bx., which laps over the other edge folded down upon the plunger L by the The bottom of the box, Fig. 11, is folded by the folders C', which turn over one end, l, of

the jsame, the folder C", which turns over or back the other end, 2, the folder 0"', which turns down the flap 3, and the folder C", which by one upward movement turns up the flap 4. The lapped surfaces of the paper are then rolled by the rollerV K', which is moved off from the box at the proper time, the plunger L previously moving outward toward the roller. The plunger L is then drawn baci: under the influence of its lever U, actuated by the cam V, and the descent of the slide N' with the rods s' attached insures the dis charge of the finished box from the machine.

The operation of each of the plungers is precisely the same as the one described.

We would remark that the covers `of the boxes are made in precisely'the same way as the bodies or main portions, the difference between the two consisting only of dimensions.'

We claim as new and desire to secure by Letters Patentl.` rlhe moistening of one edge, c, of the continuous paper roll E by means of a wooden anda metal roller, D Dx, applied to a pa per box, substantially as shown and described.
