SPECIFICATION forming part of Letters Patent No. 414,840, dated November 12, 1889. i Application filed December 21, 1883. Sen'al No. 115,294. (No model.)

.To all whom t may concern.-

Be it known that I, HENRY A. HOUSE, of Bridgeport, Fairfield county, Connecticut, have invented certa-in Improvements in Paper- Box Machines, of which the following is the specification.

This invention relates to the manufacture of boxes or parts of boxes from blanks of paper or other suitable material; and it con- 1o` sists of apparatus fully described hereinafter, and then particularly defined by the claims, for drawing the blanks into form, for carrying the blanks, stripping them from the dies, and presenting the latter properly to the blanks.

In the drawings, Figure lis an elevation, in part section, of a machine embodying my improvements. Fig. 2 is a plan with the upper portion of the machine-such as the plungers zo for operating the formers and the guides for said plungers-removed. Fig. 3 is a perspective view showing devices for guiding and delivering the formers. Fig. 4 is a section on the line l 2, Fig. 2. Fig. 5 is a section elevation taken on the line 3 4, Fig. 2, looking toward the die feeding and guiding appliances. Fig. 6 is the same as Fig. 5, showing the parts in different positions. Fig. 7 is a former in section on an enlarged scale. Fig. 8 is a perspective view, on an enlarged scale, of one form of box made by this machine; Fig. 9, an end elevation, and Fig. l0 a detail, of the driving-hub, showing particularly the stop.

The machine as illustrated in the drawings 3 5 is designed to draw up or form blanks offpaper or other material upon blocks or formers forced through a die of corresponding shape and carrying between them the blanks, the projecting edges of which are turned up against the formers to constitute the iianges as said formers pass through the die. The full description of this operation will. be found in Letters Patent No. 206,686, issued to me November 5, 1878, and need not be here repeated.

The main object of the present invention is to deposit the formers properlyupon the blanks, and to then move the blanks and formers through the die, rake off the boxes,

5o and again deposit the formers upon other blanks, continuing such operation automatically. For such purpose I employ a machine in which is a blank-carrier, a device for depositing the formers successively upon the blanks, a plunger for forcing the formers through the die, a conveyer for carrying the formers from the die, and a feeder for carrying the formers to the depositor, and a discharger, whereby the flanged boxes are stripped from the formers. I have embodied 6o these several devices and appliances in machines differently constructed, and have used such devices and appliances constructed in different ways, and will now describe in de tail one form of machine which l have found most effective.

The frame of the machine is illustrated -sufficiently to show the arrangement of essential working parts thereon, and supports a table A, guides B B., between which slides 7o a head C, carrying a plunger C and a holder or tubular die A', open at both ends, the upper end or mouth .being level with the face of the table. The die and plunger conform to the shape of the former D, a series of which are used, said formers corresponding in shape to the boxes to be made. Each former has grooves 16 at the sides, and a central stripping-plug h, terminating in a disk h at the lower end, both fittingcorrespondingrecesses 8o in the former, and a spring h2 serves to keep the parts normally in the position shown in Fig. 7.

To permit ready alteration of parts, as different styles of boxes are to be made, the plunger O is screwed detachably in the head, the die has a removable center tube c, bearing upon a bottom piece a, which rests upon a ange a of the outer casing a2 of the die; and it may be here stated that the outer cas- 9o ing a? is hollow to permit the passage of a current of steam or hot water. The upper die-plate a3 has a central flanged opening, is removable, and rests upon the tube c, which latter consists of two or more sections bolted together to facilitate construction; The open ings in the plates c. d3 and in the tube c will correspond to the forms of the former, these parts being of course changed with every change of form or dimensions in the boxes to roo be made. The space between the tube c and outer casing is lfilled with shot, pebbles, or

other granulated material, constituting a mass which will retain the heat, while permitting a ready change of the parts.

In making the boxes a blank is brought above the mouth of the die, a former is deposited upon the blank, the plunger then descends and pushes down the former until its upper face is level with the table. Another blank and former are then brought into position and forced downward by the plunger, and so on, one former forcing another through the die. The blanks are rectangular, as shown in Fig. 2 in dotted lines, and are held in a tube X above the face of the table A, (see Fig. 5,) and a plate E slides back and forth in guides Ll 4, Fig. 2, upon the face of the table, and has an opening or slot which is successively brought beneath the tube X, so as to receive the lowest blanks, and then above the mouth of the die A a stop 2, arresting the blank y (dotted lines Fig. Ll) in its upper position. A plate F extends between the tube X and the mouth of the die, partly covering the sliding plate E, and serves as a rest for the formers successively depose ited thereon, each former being then (as or after the blank is carried above the mouth of the die) slid into position upon the blanks, a rectangular guard G open at the front side receiving the former and guiding and holding it in proper position until the plunger descends. The guard G of course corresponds to the shape of the former, and is therefore detaehably secured in its position above the plate F.

The formers are delivered in proper position upon the plate F by devices hereinafter described, and are moved over the plate into the guard by a reeiprocati'ng arm H, secured to a slide H,which is reciprocated by hereinafter-described devices between guides 5 5 upon the face of the table, the arm lAI being carried to a forward position, the former then being deposited upon the plate F, and the arm ll then moving back until in contact with the guard G, thereby carrying the former into said guard.

To prevent any injuries should the plunger descend when the former is not in the proper position, I use a stopping device, (see Figs. 2, E), and 10,) whereby the operation of the machine is suspended, unless the former is earried to such a position as to move outward a pin d to a predetermined extent. As shown, the pin bears upon a rod d', carried by an arm d2 upon a shaft d, which has secured to its upper extremity a short arm d". This latter arm bears against a similar short arm di on the shaft d, which carries a trip-dog (Zion its outer end. The drive-wheel D2 is journaled loosely upon the shaft D3, and but for the clutch D would revolve independently of said shaft. The clutch D4 is a semicircular rod fitting in a corresponding groove in the shaft D3, and when locking the wheel one of its corners projects within a notch d in the hub of said wheel.

d is an arm extending outward from the cluteh-rod and held in its normal position by a spring d1". Now, as the trip-dog (17in its normal position is within the field of rotation of the arm dg, it is obvious that unless said dog be removed without said field it will trip the clutch, thereby stopping the shaft and consequently all the operating mechanism of the machine, while the driving-wheel is left free to revolve. By the formers D coming to their proper position relatively to the plunger the above-described mechanism is operated and the trip-dog thrown without the field of the clutch-arm during every revolution of the latter just before it reaches said dog. Thus the machine continues to operate. As each former with the box molded thereon drops from the lower end of the die A', it falls upon a belt-carrier I, passing around guide-pulleys G and extending in an inclined position, so as to deliver the formers upon the platform J, the carrier being provided with stops or lugs 7, arranged to pass between fingers 8, extending from the platform J, so that the forlners will slide over said fingers to the platform as the lugs move between the fingers and descend in passing around the upper pulley. Each former as it passes onto the platform strikes a pin 9, projecting from a slide K, which is reciprocated by a rotary shaft K and pitman 12, so as to carry the former forward as soon as it is delivered by the carrier I to a position designated by the letter V upon a plate L, which slides back and forth between guides 10 10, and is recessed in the upper face to receive springtongues 11 12 1.3. As the plate L is carried to its extreme left position in the direction of the arrows,Fig. 2,it slides beneath the former D, held stationary by the pin i), until the end of the tongue 11 passes ont from beneath the former and bears against the side thereof. rlhe plate L then slides to the right until the former is in the position shown at Y, when the plate again slides back to the left beneath another former deposited thereon in the position V, the former at the point Y beingheld in position by contact with a stop f upon an arm f extending from a shaft f2, rocking in bearings 14. As the plate L moves to the left, the tongue 12 springs up, and when the plate is carried to the right the end of the tongue, striking the former at the position Y, carries it farther to the right until it strikes the bent end g of an arm g, extending from the shaft f2, being then in the position Z. As the former approaches the position Z, the grooves 1G receive the guide-edges e e of two plates M M', secured a short distance above and parallel to the platform J and exte11ding'for\val'd over the plate F upon the table A. The former is prevented from moving to the left after it reaches the position Z by pressure of springclamps 17 17, secured to theplates M M and receiving the former between them, so that the former remains in place while the plate L passes wholly from beneath it, when a plun- IOO IIO

ger N, carried by the head C, will descend, and, striking the plug h, will force the box from the former into a chute O, which will conduct it toa suitable receptacle. When the plate L again moves to the right, there will be three formers in position above it at the points V 'Y Z, (indicated in the foregoing de-4 .scription,) and each will be moved one stage to the right, the end of the tongue 13 striking the former at Z and carrying it to a position U, over the plate'F, in line with the mouth of the die A, a position which is defined by a stop-arm 18, secured to the plate M. The outer section M3 of the plate M `is pivoted at 19 to the said plate, and a spring 20 tends to draw the section near the end of the plate M, so as to hold the former in position, the guideedge e being reduced upon the section M2 and entirely removed at the opposite point upon the plate M, where a vertical plate serves as a bearing, against which the former is clamped by the action of the spring 20. There is also a vertical blade il upon the section M3. The section M2 is provided with an arm j, which extends downward and carries a screwpin j', so that as the arm H moves to its eX- treme forward position it will strike the said screw-pin, swing the section M2 away from the plate M, and allow the former to drop upon the plate F, over which it will be slid into the guard G as the arm His carried backward. The plate L is reciprocated by the revolution of a crank P, carried upon a shaft 7a at its lower end, and-connected by a pitmau 7c to aA stud k3, extending from the plate L. It will be seen that the operation of the plate L and its tongue results in carrying each former by three successive stages from the position V, in which it is left by the iinger 9, to the proper position U above the plate F, another former being carried upon the plate L by the slide K as that previously deposited is movedforward one stage. A stop-finger g2 may be carried by the arm g to define the forward position of the formers at the point Y, and the arm g is lifted to carry the stops g g3 out of the way at the' proper intervals by a cam m, having lugs which are brought in contact with an arm m upon the shaft f3.

To prevent the turning or misplacement of the formers after they are placed upon the table, I sometimes use'a swinging guide Q with side ianges, which yield as the former passes beneath it, the side iianges directing the former as it moves onward.

I will now describe suitable lnech anism for reciprocating the head C, plunger N, slides E and H, and for turning the cam m and pulleys 6 6. The shaft D3 is journaled in the uprights B B', and the driving-wheel D2 is loosely mounted on said shaft, as before explained. On the other end of this shaft is a cog E3, which meshes with a cog F3 on the shaft G3 of the eccentric plunger-rod H3. This shaft G3 is jcurnaled in the uprights B B', and has on the extreme inner end a balance-wheel I3, and immediately beyond the cog F3 a beveled gear-wheel J3, which latter meshes with a beveled gear K3, secured at the end of an upright shaft L3, journaled in bearings supported by the upright B. v

The construction and operation of the eccentric plunger-rod H3, which is pivotally connected to the sliding head C, is very ordinary, and is the same as in the usual power-press.

M3 is a shaft, journaled between the uprights B B and having on the inner end a cog N3. Journaled on a short shaft O3, extending from the upright B, is an intermediate cog P3, meshing, respectively, with the cogs F3 N3, so that it will be readily understood that motion is communicated to the shaft M3 from the power-shaft D3.

Mounted on the shaft M3 are two cams Q3 R3, and pivotally hung on a cross-rod S3, extending between the uprights B B', are rods T3 T4, which latter have pins 0c y projecting across and against the edges of said cams. The lower ends of these rods are connected to the slides E H by pitmen x3 @/3, pivoted, respectively, to said slides and rods, so that it will be clearly seen that the swinging of said rods to and fro will cause the reciprocation of the slides. As the cams Q3 R3 revolve, they will act directly against the pins y', thereby effecting the swinging of the rods T3 T4. The return movement of said rods T3 T4 is accomplished by means of coil-springs 74E 75, which are secured at their ends, respectively,to the said rods and the uprighhB. The proper timing of the reciprocation of the head C and the operation of the slides E H is of course a matter easily effected by the diameters of the several cog-wheels. The lower end of the shaft L3 is provided with a beveled gear U3, which meshes with a similar vgear V3 on the end of the shaft K', thereby imparting motion to the latter. On this shaft K. are also beveled gears W3 X3,which mesh, respectively, with similar gears Y3 Z3 on the ends of the shafts a? and 7c, thus giving rotation to the pulleys G and the crank P, for the purpose hereinafter explained. The plunger, being carried by the head C,willreciprocate with the latter and forceI the plug from the former, as heretofore set forth.

I do not limit myself to the precise construction of parts set forth forcarrying the formers, as they may be varied without departing from the main features of my invention. For instance, the formers may be pushed forward from a plate upon which they are successively dropped, the movement of one shoving forward the others in Contact with each other, and sliding upon a way inclined and curved to carry them to the proper positions below the discharger N and above the plate F. I have also used other appliances for this purpose. Other appliances may also be used for carrying thel blanks successively over the die, or the plunger may carry a knife, which cuts off the Yblanks successively from a strip fed over the die.
