IMPROVEMENT lN PAPER-BOX MACHINES.

Specification forming part of Letters Patent No. 178,499, dated June 6, 1876; application filed April 29, 1874.

To all whom it may concern:

Be itknown-that I, McOLmTocK YOUNG, of Frederick, in the county of Frederick and State of Maryland, have invented certain new and useful Improvements in the Art of Manufacturing Paper Boxes, and in mechanism for making the same, of which the following is a specification:

It is the object of my invention to manufacture paper boxes from a strip of paper by one continuous connected operation.

The subject-matter claimed will hereinafter be set forth.

In the accompanying drawings I have shown all my improvements as embodied in the best way now known to me.- Obviously, however, some of the parts may beused without the others, and in machines different 1n construction from the one herein shown. The details of construction of some of the parts may also be varied in some respects without departing from the spirit of my invention, which variations would be readily suggested to skillful mechanics, or those skilled in the'art to which my invention pertains, simply by reading this specification.

Figure 1 represents a side elevation of my improved machine, showing the parts in the positions they assume when the cutter is about to severj a box from the tube. Fig. 2 is a view, partly in section, on the line p p of Fig. 1,-showiug the cams for operating the printer and tube nipper or clamp, with the parts in the positions they assume when not in operation, the cams being partly broken away to show the cam-flange by which the nipper is reciprocated to feed the paper tube. Fig. 3 is a view, partly in section, on the line q q of Fig. 1, showing the cams for operating the bottom paster and cutter, portions of the frame and cutter being broken away to show the parts more clearly-the positions of the parts being those which they occupy just after the bottom has been inserted in the tube. Fig. 4 is a view, partly in section, on the line 1 r of Fig. 1, showing the cams which operate the devices for forming and applying the bottoms to the tube. Fig. 5 is'a plan view of the tube forming and feeding portion ofthe mechanism, and the plunger for cut ting and placing the bottoms, the plungercasing being shown in section, and the devices for operating the parts being omitted. Fig. 6 is a front elevation of the shaping or forming guide. Fig. 7 is a front'elevation, partly in section, on the line 8 s of Fig. 5, of the mandrel and first forming-roller; Fig. 8, a view, partly in section, on the line ttof Fig. 5, looking in the direction indicated by the eye, showing the second forming-roller, the pasting apparatus, and printing device.

20, a rear view, partly in section, on the line d d of Fig. 1, showing the bottom forming and applying devices; Fig. 21, a mechanical plan view of the cam-flange which reciprocates the tube-feeding clamp, as it would appear when flattened out, showing the details of construction of the flange; Fig. 22, a view, partly in section, on the line 0 c of Fig. 5, looking in the direction indicated by the eye, showing the mandrel and guide between the second and thirdforming-rollers.

The mechanism is mounted in a strong frame, preferably of metal, in this instance composed of a base-plate, A. a side piece, A and uprights A A A A A and A A main shaft or cam-shaft, B, is mounted in suitable bearings in the uprights A A and carries cams, by which the operative partsof the mechanism are actuated, as hereinafter described. Aroller, (J, is mounted upon an arm, 0 hinged to the side piece A of the frame at 0 so that it may be turned. back when not in use. A tension-spring, c, on the arm bears upon the roller, to prevent the paper from unfirmly to the arm D in this instance by the screws which hold the guide D, as shown in Figs. 1, 5, 6, and 7. A forming or folding roller, D beneath the end of the mandrel, (between which roller and the mandrel the strip of paper passes,) turns up the sides of the paper, and presses them and the bottom against the mandrel, thus forming three sides of a tube. (Sec Figs. 1, 5, and 7.) The paper then passes to a second forming or folding roller, D Figs. 1, 5, and 8, which turns down one of the side flaps of the paper upon the top of the mandrel, forming a tube with one flap or portion remaining unfolded. The paper tube next passes beneath a paste-holder, E, Figs. 1, 5, 8, and 9, the lower end. of which is perforated or partly open, and provided with a brush, E consisting of a covering of cloth or other absorbent material, through which the paste, gum, or cementing substance penetrates. The upper side 'of that portion of the tube which has been turned down upon the 'mandrelpasses in contact with the brush, and

is thoroughly pasted. Removable type E are clamped by a set-screw, or otherwise suitably held, in a holder or frame, E (see Figs. 1, 5, and 8,) which is operated as will hereinafter be described, to print the desired words at intervals upon the tube while supported by the mandrel, so that each box, when finished, is labeled. After leaving the roller 1) the tube passes over a supporting plate or guide, E supported by an arm, F, secured to the side frame A (see Figs. 1 and 5,) between which plate and the mandrel the tube passes. This plate may have sides, or one or more lips or flanges, f, on each side, to constitute a guide to preserve the form of the tube, which next passes to the last forming or folding roller F, which turns down the last flap upon the pasted portion of the tube. (See Figs. 1, 5, and 10.) A plain roller, F on the opposite side of the mandrel from that on which the folding-roller F is situated, serves to brace the mandrel and preserve the form of the tube.

It will be seen that the rollers D D F and F are all mounted upon stud-shafts supported by arms projecting from the side A of the frame, and as the forming rollers are grooved or formed with double flanges, they serve to brace the mandrel and keep it in proper position independently of its attachment to the frame at the front of the machine, which is important, as the mandrel is loose at its rear end. After the tube passes the roller F it enters a casing, F which prevents the spreading or opening of the tube, and keeps the last-folded flap in contact with the pasted portion of the tube while the paste is drying .or setting. The guide or rest E before described, terminates at the roller F To insure the thorough drying of the paste I prefer to use a lamp, F, the flame of which impinges against a metal plate, G, connected with the casing F (See Figs. 1, 5, and 11.) This heater-plate or flame-cover conducts the heat from the lamp-flame to the casing inclosing the paper tube, and insures therapid drying of the paste. Instead of using the lamp the casing may be perforated to allow air to circulate therethrough, .or a current of air may be passed through the casing. The tube now passes along the mandrel, between itand the casing, to a nipper or clamp,

Fig. 12. To allow the clamp to act on the tube the casing is slotted on each side, at f f. (See Figs. 1. 2, 5, and 12.) This nipping device is preferably constructed in-the following manner: Two corresponding sides or plates, G G are pivoted in lugs g g on a supporting-plate, G which is-reciprocated, as will hereinafter be.described, in slotted arms or guides G G secured to the side piece A of the frame. (See Figs. 1, 2, and 5.) The clamp-plates G are provided with female screws, into which are screwed pointed screwpins 5 to indent the tube and prevent the slipping of the clamp when operating. The mandrel is-grooved opposite these pins to allow the paper tube to yield, and thus prevent its being punctured. To prevent the points of the pins 9 from entering too far into the paper I employ stops 9 which are formed like the pins g except that their ends are blunt instead of being pointed. These stops, being properly set, abut against the tube when the nipper takes its hold thereon, and prevent injury of the tube. The plates are normally held apart by a spring, 9 and have each an arm, g 9 Fig. 12, on their inner faces, which interlock, and by means of which the plates are caused to act together when operated upon by their cam acting through an arm, G. A cam, H, fast on the main shaft B, so as to revolve therewith, (see Figs. 1 and 2,) acts once during each revolution on the crank h of the arm G ,;to close the clamp upon the papertube, and retain it in' such position during that portion of the revolution of the cam during which the crank his ofiE the cut-away part H and in contact with the curved part h of the cam. At the same time that the circular part h of the cam H is traversing in contact with the crank h, a cam-flange, H, on the side or face of the plate composing the cam H, acts, by

means of an incline, W, on a friction-roller, h

Fig. 2, on a stud-shaft projecting from an arm, H pivoted in lugs 11/4 on the base-plate A of the-frame.

A' stout spring, H bearing-at one end against the frame-upright A and at the other against the pivoted arm H keeps the roller k in contact with the cam-flange 11 As the cam-flange revolves with its incline h in contact with the roller h the clamp-supporting plate G is moved toward the rearof the machine, as the arm H rocks in that direction, by means of a fixed stud-arm, H Fig. 2, on the arm H and a pitrnan, gipivoted at one end in lugs on the under side of the plate G and connected at its opposite end to the stud;

H As the main shaft, and, consequently, the

cams HH continue to turn, thesupportingplate (and also the paper tube, which is now' connected with this plate by means of the nipper mounted thereon) is moved toward the back of the machine-adistance equal to the length of the box being'made, the tnbeof paper passing through an opening in the upright A5, Which-opening is made (see Figs. 15'

roller remains in contact with the plain portion h of the cam. During this pause the box issevered from the tube, as will present ly be described. The roller it next has presented to it a short incline, h, on the camflange, which, acting through the rocking arm H stud H and pitman 9 moves the plate and tube still farther toward the rear, but only a short distance. While in this latter position paste is applied to the inner sides of the end of the tube, and the bottom inserted after the withdrawal of the paster, as will presently be explained. In the regular order of operation the short movement to slightly project the tube for the application of the paste and insertion of the bottom takes place, before the tube is projected the length of a box to be formed, instead of afterward, as just described. The printing device E during the last-described position of the parts, is

caused to print the desired words or devices (which can be changed as desired, as before described) upon the paper supported by the mandrel, by means of a cam,-I, upon the opposite sideor face of the plate composing the cam H from that on which the cam H is 10- cated. The curved portion 1 of this cam I acts upon a crank, 1 of an arm, 1 keyed to a rock-shaft, I rocked in bearings in the ends of the guide-arms 6 G in which the plate Gr reciprocates.

The type-holder is firmly secured upon this rock-shaft, in this instance by a'set-screw, i, which admits of the adjustment of the holder. By this arrangement the paper tube is printed at proper intervals, positively regulated by means of the joint action of the cams, .to insure each box (or each section afterward cut from the tube to form the boxes) having the desired printing upon it. As the cam-shaft continues to revolve, the cut-away part H of the cainH is presented to the crank h, upon which part the crank enters, and the spring 9 throws apart the sides G G of the clamp, releasing the tube. At the same time the part ll of the cam Ipasses from beneath the crank 1 and the shaft 1 is rocked, in this instance by the weight of the arm 1 thus throwing the type-holder out of operation, at which time it rests against a rod, 45, secured at one end to the frame-upright A, and atthe other end to the arm D This rod allows the printing device sufficient play to clear it from the paper, and also prevents the arm 1 from falling low enough to come in contact With any but the operative part of the cam I. Shortly after the cut-away part H 'ofthe cam H comes in contact with the crank it, a slope or decline, h, leading to the bottom or plain surface of a recess, H in the cam-flange H is presented to the roller 71. which is caused to enter the recess by the spring H and the plate G and clamp are moved forward by the rocking of the arm H ready-for the above-described operations, by the cams H, H and I, to be repeated as the shaft B is revolved. A pasteholder, J, (see Figs. 1, 3, and 14,) has a side projection, J at its lower end, which is open, or provided with a partially-open or perforated bottom, to which is'secured cloth or other absorbent material, through which the paste will penetrate. This holder is fastened by a clamp or set-screw, j, to a rock-shaft,j mounted in bearings in the ends of arms J J", which terminate in a rod, J (shown in this instance as forked at its lower end,) pivoted in supports j j secured/tothe base A of frame. A

cutter, K, (see Figs. 1, 3, and 13,) formed in.

A pin, f which may be provided with a friction roller, projects from the rod J and is caused, by a spring, j, Fig. 1, to bear upon the irregularly-curved edge or periphery of a cam, M, which is keyed to the main shaft, and revolves therewith.. During the time the pin j? bears against the regular portion M of the cam, the paster J J 1 is inoperative.

As the shaft revolves, the cut-away or recessed part m of the cam is presented to the pin 3' the pin entering bya decline to this recess. The rod J 4 moves parallel with the face or side of the cam, and the paster descends, so as to bring its brush or end J in line with the tube of paper. When in this position, the arm'J rests upon a stop, m secured onone of the frame-pieces, to insure the paster being in the proper position, in line with the tube of paper. An arm or tappet, M fixed on the rock-shaft j by a set-screw, now acts on a rib or projection, W, on the face of a wheel, L, fast on the shaft B. The tappet is caused to bear against this rib by a spring, M which tends to rock the tappet toward the rod J, but is prevented from swingingit too far to ward the rod by a stop-pin on the rock-shaft supporting arm J against which stop the tappet-arm bears, and is thus held in the proper position to be acted upon and rocked by the rib on the wheel L.

This rocking of the shaft j swings the paster into the end of the tube of paper, which, as before described, has just been slightly projected beyond its mandrel. Paste is thus thoroughly applied to the inside of the end of the tube. As the brush J enters it the tube may expand or yield slightly at its end where it is not confined, and thus accommodate a tight-fitting paster.

As the'tube projects beyond the mandrel and frame-upright, there is no liability of gumming or clogging the mandrel or the frame by any paste that might accidentally be applied outside or slightly beyond the portion of the tube which it is desired to paste.

. As the shaft B revolves, the tappet-arm M is freed from the cam-rib m and swings vback against its stop into proper position to be acted upon again when the revolution of the wheel brings the rib around. The pin j passes out from the recess m upon the incline leading therefrom, and the paster is moved first out from the tube, and then up to its inoperative position, the arm M being held clear of the Wheel L, and the pin 7' bearing'upon the regular part of the cam M- The parts remain in this position until the cams repeat the above-described operation. The bottom-applying device now inserts the bottom in the tube, as will hereinafter be described, and afterward, the tube' having been projected beyond the mandrel and frame opening the length of a box, as before described, the cutter strikes 01f a box fromjth'e tube. A fric tion-roller, I, mounted on a short stud projecting from the lower part of the cutter-plate K, projects into a cam-groove, L, in the face of the wheel L.

When the tube i s projected, that part of the groove marked '1 acts on the roller 1, and

causes the cutter to swing up against the bottom of the tube, cutting it half. through close to the end of the mandrel and to the frameopening, thus making a shear-cut, and not crushing or altering the shape of the tube. After this first cut the part l of the groove acts on the cutter-roller, causing the cutter to make a cut from the top downward, meeting the first cut, and thus completely severs the box from the tube.

The roller 1 now is acted upon by the part i of the groove, which leaves the cutter in the position in which it rests when not in operation, with its opening 76 opposite the opening in the frame, to allow the tube to be projected centrally through it. While in this position the roller runs in the regularly-curved part of the groove, which extends from the" termination of the part 1 to the beginning of the part P. A strip of paper, w, of the proper width to form the box-bottoms, is wound upon a roller, N, mounted on a stud-shaft, n projecting laterally from an arm, N This arm is securely attached to a reciprocating casing, N in which works a plunger, N, as will hereinafter be explained." The strip a is passed through a guide, of, and between feeding-rollers N 4 n, the guide being secured to a bracket, 0, and the feeding-rollers mounted on shafts projecting therefrom. The bracket 0 is secured to the arm N or to the casing N The roller N it will be seen, has a long bearing or sleeve, terminating in a ratchetwheel, 0, by means of which the feed of the strip is gaged and regulated. After the strip passes betweenthe feeding-rollers it enters a guide, 0 secured on the plunger-casing,which guide conducts it to an opening'in the top of the casing, through which opening the strip passes, to be acted on by the plunger-first, to cut 0d a section for a box-bottom, and then to place it in the end of the tube. A lever, 0 is fulcrumed, with a long bearing, 0 on a shaft, 0 projecting from an arm, 0 This lever is curved and caused to hear at its lower end 0 upon the edge or periphery of a camwheel, 0 (fastened on the main shaft B,) by

the action of a spring, 11 coiled upon the bearing 0"", one end of the spring resting against the lever, and the other against the cam-wheel 0 As the projection passes from under the lever it is rocked back to its normal position by the spring 19 leaving the pawl in position to resume its action, when another revolution of the cam or main shaft brings the cam in position to operate again on the lover. The space between the ratchetteeth is such as to feed the strip into the easin g-where it fits snugly--a proper distance to be cut off and form a bottom piece of the required size by each partial revolution of the ratchet-wheel. A spring bearing on the roller N prevents the strip from unwinding too freely. The arm 0 is pivoted in lugs on the base A of the frame.

A friction-roller, pion a stud-shaft projecting from this arm bears against a cam-flange, P, on a wheel, P fastened to the main shaft. The roller is kept against the cam by means of a strong spring, P one end of which bears against the upright A of the frame, and the other against the rocking arm 0 to which the roller is secured. This arm is slotted near its upper end to receive a pin secured to the plunger-casing N The plunger is secured, by means of a pin, T to a rocking arm, R, pivoted in lugs on the base A of the frame, the arm being slotted near its upper end to receive the pin. This arm is provided with a stud-shaft carrying a friction-roller, which is caused to bear against a cam-flange, R, on the face of the cam-wheel O, by means of a strong spring, R one end of which bears against the upright A of the frame, and the other end against the arm R.

1 When the strip of paper a has been properly I fed into the casing, (beyond the end of the plunger,) as before described, an inclined projection, W, on the cam-flange P of the wheel P begins to act onthe roller 1), rocking the arm 0 and causing the casing N 2 to move -toward the paper tube, carrying with it the paper strip 12. (and other parts connected with the casing,) the bent end 0 of the lever O sliding across the regular portion of the periphery of the cam-wheel O. This movement of the casing continues, as theroller is acting on the inclined part of the projection Soon after the beginning of this movement, an inclined projection, B on the camflange R of the wheel 0 is presented to the roller 1, and, as the shaft B is revolved, causes the plunger N to slide in its casing N When the plain portion, at the termination of the incline T is presentedto the roller 12 the casing has been moved forward until its end rests against the upright A of the frame, the

enlarged or shouldered part 4 of the casin g fitting over the end of the paper tube. (See Fig.

16.) During this time the plunger has been advancing, and when the casin g rests against the upright A the plunger cuts 011' the strip n a piece to form the box-bottom. This cutting is efi'ected by the upper edge of the end of the plunger acting with the edge of a cutter-plate, B secured upon the casing on the side of its top opening, through which the strip passes, as before described, the casing bein g now at rest, and the roller p acting on the regular surface or plain portion of the projection T the plunger continuing to move in the casing, pushing along before it the bottom piece, and finally forcing it into the end ofthetube, (which has been gummed and slightly advanced, as hereinbefore described without altering the shape of the tube, as it is supported on its outside by the enlargement 1 of the casing-opening, fitting overthe tube.

As the cam-shaft B continues to revolve,

The parts are now in position for the repetition of the above-described operation as the .shaft B revolves, so as to present the projections again to the rollers. that the bottom forming and applying -mech- During the time anism is at rest the tube is projected and a box struck off, as before described.

The tops for the boxesare formed by a machine similar to the one above described, and may be equal in length to the box, so as to form a sliding inclosing cover, or may be made short, like an ordinarytop.

The boxes may be made with projecting bottoms, if desired, the bottom-formin g casingand plunger being made large enough to produce bottom pieces of the desired size, the strip-feedingdevicescorrespondinglychanged,thepaster being so constructed as to apply the paste to the end instead of inside of the tube, and the bottom being presented to the end of the tube instead of inserted in it.

By changing the form of the mandrel, and

correspondingly altering the forming-rollers,

mandrel-casing, and bottom-forming devices,

boxes of different shapes may be manufactured.

Instead of the knife-cutter herein described, to sever the boxes from the tube, rapidly-revolving circular saws may be employed, and be swung up automatically to the tube from opposite directions to strike of the boxes.

The main or cam shaft is shown, in this instance, as revolved by a hand-crank; but it is obvious that themechanism may be driven byany suitable motive-power. It is also 0bvious that the same set of cams may be employed to operate two or more machines, and thus the rapidity with which the boxes may be manufactured increased.

I claim as my invention- 1. The improvement in the art of manufacturing paper boxes by machinery hereinbe fore set forth, which consists in forming a tube from a strip or web of paper, pasting together the lapping edgesof said tube, pasting the end of the tube, applying a separatelyformed bottom piece to the pasted end of said tube, and severing the tube to form a box of proper length, these operations being automatically, successively, and repeatedly carried out by mechanism substantially such as described.
