Application filed October 13,1893. Serial Nu.488,190. (No model.)

Machines, of which the following is a specifb' cation.

This invention relates to improved mechanisms embodied in an automatic machine for gumming paper box blanks and for folding them and insuring the adhesion of the adjacent corner flaps or wings.

Theimprovements more particularly relate to-the gumming and picker mechanism, the

blank conveyer, the foldingand setting mechanisms, as to their constructions and thecombination or arrangement of certain thereof to each other, and, incidentally in connection with these mechanisms, the invention relates to subordinate features for utility and novelty, as will be hereinafter rendered manifest.

The invention also has reference. to constructions and arrangements whereby the machine may be utilized for making boxes of diiferent shapes and sizes; and the invention consists in various constructions and combinations of parts, all substantially as will hereinafter fully appear and be set forth in the claims.

Reference is to be had to the accompanying drawings, in which the invention is fully illustrated, wherein- Figure 1 is a plan view of the box making machine. Fig. 1 is a perspective view of certain of the driving connections for the blank conveyer. Fig. 2 is a side elevation of the machine, and Fig. 3 is a front elevation of the same. Fig. 4 is an illustrationin perspective of one of the end setting followers. Fig. 5 is a perspective view showing one of the corner wing folders and the piece to which it is connected. Fig. 6 is a vertical section on a large scale taken through a part of the folding and end setting mechanism about on theline 6-6, Fig. 1. Fig. 7 isa plan view of parts seen in Fig. 6, the folding plunger being shown in horizontal section. Figs. 8, 10, and 12 are vertical sections taken substantially onthe plane 7 indicated by the line 6-,-6, Fig. 1, (and someof the folding operation, while Figs. 9, 11, and 13, are sectional elevations of the same. Fig. 14 is a perspective view on a large scale showing the formation and arrangement of the parts at the corner of the folding throat or box. Fig. 15 is a plan view of the blank from which the box is produced. Fig. 16 is a perspective view showing the relative disposition of the parts of the blank at the corner of the completed box. showing a slight modification which may be practicably made in the form of the blank at the stay section.

Similar characters of reference indicate corresponding parts in all of the views.

A,-Fig. 15, and also Fig. 1,-represents the blank from which the box is formed, the same comprisinga rectangular middle section, a, as bounded by the scores or bending lines, a outside of which are the side sections, b, b, and end sections, b b the lengths of which are equal to the proximate boundaries of the middle section, the widths being equal to the height of the'box (or box cover). The blank also comprises the stay sections, d,.which are formed as endwise continuations of the opposite side sections, there being between them and the said side-sections the scores or bending lines, a These stay sections are of trapezoidal form, as rendered by the diagonal cut at d These sections might, however, be triangular, as indicated in Fig. 17.

In making the box the side and end sections are bent up at right angles to the bottom, the wings or stay sections are turned at right angles to the side sections from which they are unsevered and lie against the inner sides,

near their ends, of the end sections, being stuck thereto by the gum, or usual adhesive,

'no separate stay strips of tape or other flexithereunder, whereupon the blank is detached from the picker and falling upon the conveyor Fig. 17 is a plan view is, by the latter, carried over the folding box, or throat, and under the folding plunger, all very much in the manner of handling blanks for envelopes. The walls of the rectangular throat or folding box stand normally opened from each other leaving the opening larger than the plan of the box, said walls being inwardly movable, and have movements imparted periodically to them, whereby the infolded wings are properly brought to the squared form andhave their ends squeezed hard against the plunger to set the gummed stay-sections. The folded and stuck boxes are then permitted to fall down through the opening at the bottom of the folding box to be cared for in any suitable manner.

The gummer picker, as seen in Figs. 1, 2 and 3, comprises the vertical reciprocatory shaft, f, the motion to which is imparted in the manner usual in envelope machines, and this shaft has secured to its lower end the horizontal, transversely ranging bar, or rigid rod,f This rod has, adjustably fitted at each end, the split collars, f held by grip uts, f, in and through both of which collars are secured, by their middles parallel, and forwardly and rearwardly ranging rods, 9*, g";

on the end portions of these rods are adjust,

ably fitted and held by the set screws, 9 the split hubs, 9 of the pickers, g; the picker members, proper, standing-in parallel front and rear-pairs, or at the corners of an imagis nary rectangle coinciding with the ends of the end, sections of the blank, and all as plainly seen in Fig. 1. The gumming impressions of the pickers are also seen at 9 in Fig. 15. By properly adjusting the bars, 9 along the bar, f the pickers may be arranged for gumming the blank for a box of different length;-and with the pickers set for any given length, by adjusting them individually fore and aft on the bars, g", g", they may be made to accord with the blanks which are provided for boxes of a differing width.

The folding box, or throat, the sides of which are movable, are constituted by the end followers, B, B, and the vertical plates or blocks, D, D, D, D, front and rear pairs of which are mounted on the slides, E, E. These parts have, at proper times and when the folding plunger, E, is well down, their closing-in movements, as will be hereinafter set forth, but they stand, when the plunger is up, at the boundaries of a rectangle some. what larger than the plan of the completed box, and at, or near, the boundaries of the rectangular opening, a:, at the opposite ends of which are the hinged bottom sections, deriving their swinging movements in the manner hereinafter described.

The end followers, and their actuating means, are fully and clearly shown in Figs. 1 to 4, and 6 to 7; and each of these duplicated mechanisms comprisesa bottom slide, 20, constrained, for slight extents of horizontal rectilinear reciprocatory movements, by the grooved formations seen at 22, whichinsure support and guide engagements with the boundaries of the apertures, 23, transversely formed in the table, as continuations of the throat-opening,w. And the slide has, at its inner end, the right angular and upright member constituting the follower proper, B, the height of which is to be approximately that of the box to be formed in the machine. The follower-slide is centrally and longitudinallyaperturedoutsideof the upright member, as seen at 24, and has at its top rear end the substantial bearings, 25, 25, for the trunnion-like journals, 26, 26, of the collar, 27, which hasits location withinthe said aperture. Through this collar is the shank of the screw-shaft, 28, the engagement being adjustably insured by the two lock-nuts, 29, 29. This screw-shaft forms one member of a toggle-joint, the other member thereof consisting in the link-piece,

30, which has the bifurcated formation at 32,

" apertured support block, 33, firmly bolted to the table near its lateral edge. The said toggle member, 30, has the depending ear-pieces, 34, 34, within and pivotally connected to which is the upper end of the thrust-rod, 35, which is operated through means of the cam, 36, on the main shaft, 0. The slides, E, E, which are at the front and rear of the said opening, 00, havetheir reciprocatory movements on the top of the bed toward and from the front and rear edges of the said opening, and at right angles to the line of movement of the followers, B, B. The slides have the slots, 40, longitudinally thereof (which slots are transversely of the table of the machine) in which are set the depending ribs, 42, of the clamp blocks, 43, which are provided with the upwardly extended edge flanges, 44, 44. -The aforementioned vertical blocks, or plates, D, D, have their horizontal right angular members, 45, fitted in the clamp blocks, these members, the blocks, and slide, all being confined by the bolts, the shanks of which pass down through the parts, 45 and 43, and the slotted slide, the nut locking them in the confinemen't when adjusted.

It will be seen that the vertical plates, D, D, have their location within the opposite edges of the aperture, w, their upper edges being,-as will be seenin Figs. 6 to 14,-somewhat higher than the upper edges of the followers. The properly timed and periodically reciprocatory movements are imparted to the slides, E, E, by the connection therewith of arms, 46, extended from the rock-shaft, 47, 47, each rock-shaft having a radial arm, 48, with which is con nected the upper end of a thrust-rod, 49, which receives its reciprocatory movement in one direction by the main-shaft cam, 50, and in the other by the spring, 51. The plates,

D, D, of the front and rear pairs stand in coinciding planes which are within the ends of the followers, 13, the outer edges of the plates being quite near the working faces of the followers even when the latter are retreated. These plates, D, are, therefore, as manifest, adjustable edgewise toward or from each other, that is, along the lengths of the slides, E,and also are adjustable inwardly, transversely of the slides, to accord with different-sized box blanks, the adjustment of the followers, at their connectionswith the screw-togglemembers, being necessary to accord with the edgewise adjustment of the plates, D, for changes of length. Were it not for the purposes of adj ustinent ofthese plates, D, as above explained, a single wider plate of the required formation might be provided non-adj ustably as to its width at, and upon,the front and rear slides. Each plate, D, stands a little higher than the top of the follower, its upper edge being upwardly and outwardly beveled, as seen 'at 52, and each plate has at its upper corner toward the follower, a projection, g, which as regarded relatively to the dimensions of the plateD extends longitudinally outwardly from the edge, and also laterally inwardly from the face of the plate, D. The upper surface, 53, of this projection is on a bevel corresponding to, and as a continuation of, the bevel, 52, of the upper edge of the plate, while its inner face, 54, which is opposite from the working face of. the follower, is'downwardly and inwardly beveled, toward the plane of movement of the vertical end of the plunger, see Figs. 1, 5, and 6. lower is forced up to edgewise contact with the plates, D D, its upper surface is closely under the aforesaid projections, g, g. The conveyer, to be soon described in detail, brings the flat blank from the pile, at the front, to a position over the throat, the-side sections, 5, b, overlying the upper edges of the plates, D D, the stay sections in part overlying the projections, g, while the end sections overlie the tops of the followers. The relations of these parts are shown in Figs. 6 and 7, the heavy broken lines in the latter figure indicating the blank, the parts, D and B, being shown as retreated. Now, before the said retreated parts move to their contracted relations, the folding plunger descends and as the middle of the blank is, by the plunger, forced down, the opposite side sections, 1), are bent angularly to the bottom section, a, and the staysections, d, are, by the beveled faces, 54, of the projections, g, caused to assume, more or less nearly, right angular relations to the side flaps, aswell as to the bottom, all as will be clearly understood on reference to Figs. 8 to 16 of the-drawings, in connection with this description. It will be perceived, Figs. 10 and 11, that as the plunger descends so far as to cause, in its cooperation with the

faces

52, 54, the sections,

1), d, to have their top edges nearly vertical and about coincident with the under surfaces of the projections, g, and the end sections, 17 to stand angularly to the bottom section,.a, the slides, E, are moved inwardly causing the plates, D, D, and the edge or corner, 55, of

When the fol-' the projection to have positions snugly up to the sides of the plunger, the said blank sections, 1), d, of course assuming positions next to the plunger; and now each of the followers begins to move inwardly, finally assuming the position seen in Figs. 12 and 13. As the followers come up and remain hard against the blank sections, 5 d, insuring the setting of the adhesive, and at atime when the bottom of the plunger is level with the bottom of the followers, the hinged bottom sections, G, G, are forcibly swung up against the bottom end portions of the box, and, together with the followers, efiect the positive shaping and setting of the box.

It will be perceived in the drawings that the end of the plunger isreduced or rabbeted, as at 57, at its ends between its corners, so that the entire end pressure by the followers against the ends of the plunger is next to the corners, where only is such pressure necessary. The bottom sections, G, G, are in the form'lof plain rigid rectangular bars, and are hinged near the lower corners, at their working ends, of the follower slides, as fully and clearly shown in the drawings. Each said hinged section has connected thereto the thrust-rod, 58, operated by the properly timed and guided cam on the cam-shaft.

Each of the vertical members, B, of the followers has, within its working face, a recess, 65, in which is set a plate, 66, having its upper portion overturned to form a hook, 67,

which stands outwardly beyond the face. of the follower, at a place opposite the rabbeted part, 57, of the plunger. As the plunger, after having forced the blank down against the bottom sections, G, retreats rapidly upward before the followers have retreated much, should the box hang upon the plunger it will, by the said hooked clearingdevice, be stripped therefrom and will, i of course, fall down through the throat opening as the members constituting it expand or recede.

The blank conveyer comprises the parallel opposing horizontal bars, h, h, each of which has the longitudinal upwardly extended rib, or feather, 70.

The follower members, B, B, have endwise through them, which is .fore and aft of the machine near their upper, inner corners, the ways, 72, for the said feathered conveyer-bars, said ways having the contracted openings leading to the upper surface of the-follower members so that the feathers 70, stand with their edges considerably above the said upper surfaces. While the conveyer-ba'rs move longitudinally thereof through the conveyers for the purpose of receiving thereupon the blanks and carrying them to their positions .over the folding box, they necessarily have,

by reason of their support upon the followers, movements transversely of their lengths bodily with the followers; and to permit this action each of the bars has, at or near its rear end the angularly extendedperforated' lug,

75, while through the perforation, 76, of these ends being rigidly supported, as at 82, to suitable parts of the rock-shaft, 83, which is mounted in suitable bearings therefor of the framing. This rockshaft has the radial arm or crank, 8at,which,bya link, 85, is connected to one arm, 86, of an intermediately pivoted lever, the other arm, 87, of which has the roller stud in working engagement with the eccentric or cam, 88. The spring, 89, insures the movement of the last described parts in a direction opposite to that in which the said parts are positively forced by the cam.

The rib or feather 70, which stands above the top of the follower, B, constitutes, in a certain degree, the former member, or part, coacting in the upward and inward turning of the end sections, 5 as will be apparent on an inspection of Fig. 8; the upper part of the follower, B, might be downwardly and inwardly beveled whereby the adequate folding action would be derived, but by the construction shown, wherein the feather stands above the longitudinal way, 72, at its upper orifice, there will be no liability of the lubricant, which is liberally provided in the slideway, coming onto the surface of the blank.

Inasmuch as the upper edges of the plates, D, are higher than the tops of the followers, B, and the plane of movement of the conveyer bars, h, the front pair of the plates have the sheet metal upwardly and rearwardly inclined deflectors, 81, to raise and guide the rear edge of the rearwardly moving blankas itassumes its position over the folding throat.

The elevating mechanism for the blanks and the means for supplying the pickers with gum are not herein particularly described as they constitute no part of the novelties of this invention and may be substantially as usual and well known in envelope machines.
