Apoatisn filed August 7, 1896. Serial No. 602,038. (No model.)

To all wir/om, fr? muy fio/marre.:

Be it known that we, JOHN T. ROBINSON and HENRY J. CHAMBERLAIN, of Hyde Park, county of Norfolk, and DEsBRoW M. SMITH, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Quadruple Scorers, oi which the following description, in connection with the accompanyin g drawings, is a speci cation, like letters on the drawings representing like parts.

This invention has for its object the p'roduction of an apparatus for scorin g paper to be made u p into boxesin such manner that the waste is reduced to a minimum and the two sets of scoring at right angles to each other can be made in a rapid and efficient manner.

In thc apparatus to be hereinaf ler described the sheet of material is fed beneath a series of scorers, which score the surface in parallel lines as it passes thereunder. One or more cutters divide the sheet into separate parts, it desired, as it passes through or beneath the first set of scorers, and as it frequently happens that the size and shape of the sheets of material would cause a great amount of waste if the entire sheet was fed through the second set oi' scorers we have provided means whereby, when it is so desired, a certain portion of the sheet only will he automaticall)T fed through the second set of scorers'to thereby completely score such portion, the other part of the sheet being delivered directly from the first machine at a suitable point and scored in only one direction, or not scored, to be thereaftersubjected to the action ci' a second set of scorers, arranged or set according to the size of the severed portions of the sheet and according to the size and shape of the box which is to be made therefrom. The part of the sheet which is to be automatically fed through the second set of scorers, or in some instances it maybe the whole sheet, is delivered upon a table or support, from which it passes to the second set of scorers, and in order that the feed to the latter set may he effected with great rapidity and without interfering with the following sheet we have located the support or table below'the plane of the delivery from the "first machine, wherebyas a sheet. is boing delivered from the first set of scorers the next preceding sheet is being fed at right angles thereto and beneath it to the second set of scorers.

In accordance therewith our invention consists in the construction and arrangement of parts to be hereinafter fully described, and particularly pointed out in the claims.

Fig. 16 is an enlarged detail view of the connecting mechanism between the two bed-rolls, and Fig. 17 is a detail plan view of the waste-controlling device shown in Fig. 13.- f

Referring' to the drawings, we have shown the operative parts as mounted upon two frames A B, of suitable shape, to provide bearings for the working parts, said fra m es being connected by a substantially rigid casting C, for a purpose to be described.

The frame A is provided with bearings for the main shaft A', provided with a suitable pulley A2, herein shown as loose on the shaft and adapted to be brought into engagement therewith by a suitable clutch mechanism, although it is obvious that in lieu thereof tast and loose pulleys might be substituted provided with a usual belt-shipper of well-known construction.

The main shaft has fast thereon or forming a part of it a bed-roll A3, over which the sheet of paper or other similar material is fed to be acted upon by the scorers A4, which are and may be substantially as shown in United States Patent No. 273,391hdated March l5, 1883, the scorers being mounted upon a scorer-support A5, adapted, as in said patent, to receive a series of scorers upon its upper and lower edges, whereby by rotating the support in its bearings one series of scorers, laterally adjusted according to the work to be done, may be substituted for a second series of scorers at the other side of the support.

A guide-plate A, of usual construction, is mounted above the bed-roll A3 at the feed side of the scorers to direct the leading edge of the sheet beneath the scorers, and, as shown in Figs. l and 7, we have arranged a feed-con-l trolling device to permit the entrance ot' a sheet to be scored at the proper time.

Brackets a are secured to the cross-girth A7, preferably toward the left-hand side of the feed-table A8, to form bearings for a rockshaft d', to which are secured blocks CL2, having fast thereon detents CL3, shown as bent over or hooked at their lower ends to normally project through slots a4 in edge-guides a5, shown as inclosing the detents, and bent upward and over the tops of the brackets and secured thereto, as by suitable screws d6. (See Fig. 7.) n

The rock-shaft has secured thereto a post or stud d?, to which one end of a spring s is' attached, the other end of the spring being` secured to an upright as on the cross-girth AT or other fixed part of the apparatus, the tendency of the spring being to normally maintain the detents in the position shown in Figs. l and 7, with their hooked lower ends projecting through the edge-guides d5 and preferably beiow the edge of the feed-table A8 and in the path ot the sheet to be fed.

It will be obvious from the foregoing that whenever the rock-shaft a' is partially rotated until the detents are moved int-o dotted-line position (shown in Fig. 7) the sheet of paper may be fed forward beneath the guides d5 and upon the bed-roll A3 to be scored, the releasing movement of the detents beine` timed, as will be described, to deliver the sheet uponl the intermediate table at the proper time. As the scored sheet passes from the bed-roll A3 it is to be delivered altogether upon an apron b to and to Abe engaged by a. pair of delivery-rolls h h2, Figs. 2 and l5, or a part of it will pass over said apron to the delivery-rolls, and another part will be directed beneath the frame A to a suitable point. As the sheet is fed over the bed-roll A3 each of its longitudinal edges is trimmed by suitable trimming-cutters mounted on the support A?, one of such trimmers, as AX, being shown in Figs. 4 and G, and just beyond the trimmers and at their outer sides we have mounted stri p-guides d10, shown as curved pieces of metal adj ust-ably secured to a crossrod a, as by set-screws cl2, so that the said strip-guides maybe adjusted laterally with the trimmers AX, the supporting-rod du being mounted in suitable supports L13 (see Fig. 2) at the sides of the frame A.

In order to feed, as it were, the severed waste strips positively away from the bed-roll and strip-guide d10, we have mounted upon a rod du a rocker di, Figs. 4, 5, and 6, having at its upper end a stud als, upon which is mounted a roll d, held `in contact with the bed-roll A3 by suitable means, herein shown as a weight 'w on the end of an arm als, secured to the rocker, the latter being bifurcated to straddle an adjustable collar al", held in ixed position on the rod d1v1 by a suitable set-screw d20, so that the rocker is free to swing upon the rod, but is held from lateral movement thereon. A chute ax, having secured thereto a hub or sleeve 2.21, is supported on the rod a in such manner that the mouth of the chute will be beneath the point of contact of the rolls A3 and a, and in the operation of the device the waste strip as it is cut from the sheet enters beneath the strip-guide al@ and is guided thereby underneath the auxiliary roll d, and by the continued rotation of the bed-roll A3 the severed or waste strip is directed positively into the chute (LX, from which it is discharged at the front of the machine. It is to be understood that one of these waste-controllin g devices will be located at each side of the sheet if each side is to be trimmed. 'Were it not for the auxiliary roll d the waste-strip would be liable to crowd into and jam the space between the bed-roll and the strip-guide al, from which it would have to be cleaned from time to time.

Supposing `now that the entire sheet as it is delivered .from the rolls h h2 is to be scored by a second set of scorers at an angle to the first score-lines made7 the sheet is delivered upon an intermediate table or support D, over which it is to be moved as it is fed rig to the second set of scorers. At the longitudinal edge of the table B, beneath the delivery-rolls b b2, is located a raceway composed, as herein shown, Figs. 2, l2, and l5, of two separated sides o and c', longitudinally grooved at their inner faces to form a track for a crosshead c2, reciproca-ble therein, the said sides being secured to cross-girths B', (see Figs. 3 and 15,) forming a part of the extension B2, which supports the table D.

- Referring to Figs. 3 and l2, the two parts of the raeeway have depending therefrom suitable ears eX, through both of which is loosely extended a rod c3, threaded at its ends to receive check-nuts n n', whereby the sides of lthe raceway are maintained in parallelism and Wear may also be compensated for, one such connection being located, preferably, at

each end of the raeeway and outside of or beyond the throT of a depending` foot c4, (see also Fig. 15,) secured to or forming a part of the cross-head ci, pivotally connected by a link ci to a crank-arm c on a cam-shaft c7, mounted in suitable bearings in the frame B, and having fast thereon a pulley e8, rotation being transmitted thereto by means of a suitable belt e, passed over a pulley o10 on the bedroll shaft B3 of the second series of scorers to be described.

The cross-head e'l is longitudinally grooved in its upper face at c11 to receive therein the tongue d of a feed-gage d, suitably secured thereto, the tongue being at right angles to the gage, the said gage being held in adjusted position on the crosshead by means of an adjustingscrew d2, the shank of which extends through the gage and tongue d and into a square-sided T-nut cl3, held in an undercut groove c12 of the cross-head, the head of the set-screw d? entering a counterbcred hole in the gage, as best shown in Fig. Turning the set-screw to screw it into the T-n ut draws the latter againstthetop of the groove c12 and pulls the gage and tongue tightly againstV the cross-head.

It will be evident that the cross-head has a constant throw or stroke, but that by varying the position of the feed-gage d upon the crosshead relatively to the ends of the latter the said gage is adapted to feed paper ofdifferent widths, and such adjust-ment is effected by loosening the set-screw d2 and then sliding` the gage along the cross-head to desired -position, after which the set-screw is tightened.

The feedgage is extended laterallyover the auxiliary table D and rests thereupon in its movement back and forth, and as a sheet is delivered from the relish Ui it passes beneath the downhold, to be described, and over the feed-gage d, which at such time is in the forward part of its stroke, feeding the preceding` sheet to and to be acted upon by the second set of scorers.

Upon the feed-table D we have mounted standards e, one near each corner of said table, and on a rod b3, supported. in the delivoryroll stands bx and bx', are mounted collars bi, to which are attached in any suitable manner, herein shown as hollow bosses or hubs, one end of the rods e, the other ends of said rods being held in the tops of the standards e by suitable set-screws eX. The cross-rods e form supports for the downhold for the sheet as it is delivered from the rolls b' b2. As the leading edge of the sheet is delivered from the rolls b b2 it is necessary to direct it out over the table D in such manner that the sheet Will lie fiat thereon when the feed-gage d engages one of its trimmed sides to feed the sheet forward to the second set of scorers, and it is also necessary to prevent retrograde movement of the sheet after it leaves the delivery-rolls, and all this we have accomplished by supporting above the sheet and to act upon it a iiexible downhold, which permits the passage thereunder of the sheet as it is fed forward over the table D to a stopgage, to be described, but which prevents retrograde movement of the sheet, the construction of the downhold being such that the gage d is free to reciprocate back and forth beneath it.

We have herein shown the downhold as composed of a brush f, extended parallel to the delivery-rolls and suspended from the cross-rods e by lingers e2, depending from collars e3, held in adjusted position on the rods by suitable set-screws e4, and with large sheets it is preferable to use two or more such downholds, according to the size and shape of the sheet and the material of Which it is composed. The brush is preferably composed of IOO bristles or fibers inclined at an angle to the plane of the table D, the. leading edge of the sheet moving under the fiber or bristle and being thereby smoothed or pressed out flat upon the table, while it Will be obvious that the feed-gage may move back and forth be neath the fibrous or bristle portion of the brush in the subsequent operation of feeding a sheet.

The brush-like downhold presents little obstruction to the forward movement of the sheet thereunder, but acts to prevent its retrograde movement as the points of the bristle or fiber then take hold of the surface, and the friction exerted thereby is sufficient to hold the sheet in place.

A gage-rest gis secured to the table, the upturned lip g forming a longitudinally-extended support for a slidebloek g2, in which is mounted one end of a stopgage support, shown as a rod g3, the other end of the said rod resting on the supporting-rod b3, which latter also supports a binder B6, loca-ted just. back of the delii-Yery-rolls b' b2, Figs. 2 and 15, and acting upon the top of the sheet as it moves across the apron b to the said deliveryrolls.

Referring to Figs. 2 and El, the stop-gage lis shown as an arm g", mounted to swing on the support g3 and of such lengt-h that its lower end or foot normally bears upon the surface of the table D, the stop-gage being inclined IIO at an angle of about thirty degrees to the horizontal to rock as the feed-gage passes beneath it, and also if the leading edge of the Y paper is very rough, the corners g5 of the gage nearest the second set of scorers being upturned or curved to permit the movement thereunder of the feed-gage d as it is retracted to engage the trimmed edge of the sheet, the leading edge of the sheet as it is fed across the table D by the delivery-rolls being engaged by the dat side of the stop-gage g4.

It sometimes happens that the leading edge of the sheet is not true or continuous, and in Order to avoid presentingthe sheet improperly to the second set of scorers, as would be the case if the stop-gage were of considerable extent, we make use of the comparatively narrow stop-gage g4, which acts upon only a small part of the leading edge of the sheet, permitting the sheet to be turned about-such engaging portion when the feed-gage (Z engages its true-trimmed edge sufiicientl y to straighten or true the sheet before the feedgage moves :it forward to the second set of scorers. Y Supposing now that a sheethas been delivered from the rolls Zi' h2 upon the feedtable, passing beneath the yielding downhold described and against the stop-gage, the feed-gage d as it is moved toward the outer end of the table D will slip from under the edge of the sheet, allowing the latter to rest upon the surface of the table, and at the next forward reciprocation of the feed-gage the sheet will be moved forward between the bedroll B3 and the second series of scorers, two only of which are shown in Fig. 2 at B4, to be scored at right angles to the first scoring imparted to the sheet. Vhile this sheet is being fed forward the feed-controlling detents CL3 have been operated to permit the entrance of another sheet between the bed-roll A3 and the scorers A, and such second sheet will beV delivered by the rolls b b2 above the rst sheet and while the feed-gage is feeding it forward7 the yielding downhold permitting the second sheet to slide thereunder and over the rst sheet, the bite of the delivery-rolls preventing displacement of the second sheet, due to the feeding motion of the first one underneath it.

The second sheet is not released from the delivery-rolls b b2 until the next preceding sheet has been removed from beneath it.

The scoring mechanism of the second set of scoring devices is substantially a duplication of what has been hereinbefore described.

Referring to Fig. 1, the box-like connection O is broken out to show therein an intermediate shaft B30, (see Fig. 16,) which is fast tothe bed-roll B3 of the second scoring mechanism, said shaft having thereon one member, as CX, of a clutch adapted to be brought into engagement at times with the other member, CX, of the clutch, provided with a bevel-gear 50 in mesh with a second bevel-gear 51, (see dotted lines, Fig. 16,) the latter having a gear 52 thereon in engagement with an intermediate gear 55, which in turn meshes with a gear 54, connected with the hub of the belt-pulley A.V The two members of the clutch are brought into engagement by a usual cone C2 on a slide-rod C3. controlled by a hand-lever C4, so that the operator may throw the second scoring mechanism into or out of operation, as desired. The cam-shaft c7, Figs. 3 Vand 14, has fast thereon a cam C5, adapted to act upon a lever C, secured to and to rock'a shaft O7, mounted in bearings in the two frames A and B, said rock-shaft having a toe CS, Figs. 1 and lA movable beneath an ear or offset C9, secured to a slide-plate C10, having a pin 20 thereon to bear against and lift an arm C12, fast on the rock-shaft a when the slide-plate C10 is raised, the said plate being guided by suitable headed studs 25, extended through longitudinal slots in the plate and into the frame of the machine. The lever C3 is held against the cam C5 by a suitable spring S, and the rotation of the cam causes the feed-controllin g detents a3 to be operated at the proper time to permit the feed of the sheet into the first set of scorers. The box-like connection C also has within it a train of gears G50, Fig. 1, between and connecting the gears 54 and 504, the latter being fast on the inner end of the lower delivery-roll b', said roll at its other end (see Fig. 2) having thereon a gear 505 in mesh with a gear 505 on the adjacent end of the upper roll. As the sheet is passed through and acted upon by the second scoring mechanism it is delivered therefrom upon a delivery-table H, a binder B25, of usual construction, preventing the sheet from rising and maintaining it flat as it is subjected to the action of the second scoring mechanism` as best shown in Figs. 1 and 14.

The delivery-table l-I is shown best in Fig, 14 as inclined downwardly away from the scori ng mechanism to receive thereon the successive sheets, and said table is mounted upon a series of posts 7i, adapted to slide vertically within a frame formed by corner-posts h and braces h2. A drum-shaft h3 is mounted in the frame and provided with drums h4, (see Figs. l, 2,and14,) about which are wound iiexible connections h5 and It, secured, respectively, at points adjacent the front and rear supporting-posts of the table H, the connections t passing directly therefrom to and about the drums, while the connections h5 pass over intermediates tT-on the braces h2, and thence to the point at which their outer ends are secured.

From the foregoing it will be seen that rotation of the drum-shaft in the direction of the arrow 50, Figs. l and let, will elevate the table H, and this may be done by means of a suitable hand-wheel H on the projecting end of the shaft. The said shaft is provided (see Fig. 1b) with a ratchet-Wheel hs, adapted to be engaged by pawls 72.9,pivoted on the interior of a flanged friction-pulley hw, and rotatable with the d ruin-shaft When the latteris rotated IIO IZO

in the direction opposite the arrow 50, Figs. l and ll.

rl`he periphery ol' the brake member 71.* is partially embraced by the stationary brake member, herein shown as consisting ot two parts 71.12 and 71H3, connected at opposite sides of the flanged member by bolts h1" and hw, one or the other of said bolts being provided ywith a suitable thumb-nut 71?, whereby the' friction between the two members ot the brake may be varied according to circumstances.

Supposing that the table ll is elevated, as shown in Figs. l, 2, and il, and the frietionbrake adjusted, as the sheets are delivered upon the said table their increased weight will cause the table to gradually fall, thus permitting the sheets to form a pile automatically, while the fall is so gradual that the top ot' the pile will be below and near the point of delivery of the sheet, and when the movement of the table has been completed the sheets of paper thereon may be removed, and rotation of the hand-wheel in the direction of the arrow will elevate the table to normal starting position, the pawls hg at sneh time slipping over the teeth of the ratchet hs ready for a new load of scored sheets.

It is sometimes not only convenient but necessary that oniya part of a sheet be passed through the second scoring mechanism, and it is desirable that the other part of the sheet be delivered automatically at another point without interfering with the operation of the machine. To accomplish this, we have provided the framework A with a sheet-turning device located below the table B, said sheetturning device consisting of a series of curved guides ne, secured each to a. bifurcated support m', embracing a cross-rod m2, and held rigidly in place thereon from lateral movement by a suitable set-screw ma, each support straddling a roll m, mounted to rotate on the cross-rod in?, and held from lateral movement by the adjacent support. These rolls m4 bear against the surface of and are driven by the paper as it passes between them and a roll for, extended across the framework A below and parallel to the bedroll A3, said roll m5 being positively driven by a belt 'm5, passed around a pulleyml, (see Fig. 5,) fast on a short shaft m3, extended through the frame, and having thereon a pulleym, driven by a belt mi@ from a pulley lm1L on the main shaft A'. Each of the curved guides m is longitudinallyT slotted at its upper end, as at mx, Fig. 4, to receive therein a pin n2 and the shank of a set-screw n3, both mounted in a switch-plate n, curved for a part of its length to correspondto the eurvature of the guide m, the upper end of each switch-plate being bent or offset at a5 to permit the tip n of the switch to clear the downturned end of the apron b, which projects over the cross-rod all. then the switches are in the position shown in Figs. e and 5,

the portion ot the sheet which engages them will be turned or de'lleeted downward thereby, and, such portion of the sheet following the curve of the guides m, it will be turned and led between the rolls mil m5 and delivered beneath the machine onto a truck or other suitable receptacle it desired.

It is to be understood that the cross-rod m2 will be provided with as man y sheet-turning guides fm as are necessary, and that said guides will be located only in the path of that part of the sheet which is to be deflected below the apron Z) by means of the switches described, and obviously, if desired, the whole sheet can be deliected as itleaves the iirst scoring mechanism and delivered beneath the apparatus, as described.

It the sheet is cut into two parts as it receives its rst scoring, one part of each sheet can be delivered to the second scoring mechanism, as hereinbefore described, and the other part of the sheet deflected and delivered below the machine. This adaptability of the apparatus is a very valuable feature, as it saves a great amount or" waste and increases the output ot the machine, for it will be evident that if the sheets are to be severed and one part doubly scored, the two parts of the sheet may be scored diti'erently by the first scoring,` mechanismthat is to say, at different distances apart-so that one part of the sheet is adapted for boxes of one kind or size and the other part of the sheet for another box.

A shield 0, located at the front of the frame A, prevents the sheets as they are delivered thereunder from sliding or jumping toward the front of the apparatus and underneath the intermediate table D, and also keeps the said delivered sheets separated from the waste.

lVhile we prefer to use the downhold and stop gage heretofore described with some classes of work, a modilication of both parts may be used with good el't'eet, such modified forms being illustrated in Figs. l0 and l1.

The downhold shown in Fig. ll consists of a bifureated support i', adapted to be mounted upon the cross-rod b3, and held from longitudinal movement thereon by means of a collar or hub r", maintained in position by a set-screw (50, the said support being adapted to receive therein a preferably hollow shank fr?, into which is telescopically extended and held in adjusted position by a set-screw a rod r3, upon the outer end ci which is secured a forked bcarin g frL for the journals r of a roll r, preferably having a cover rl of rubber, felt, or other suitable material, the said roll being adapted to rest upon the surface of the sheet as delivered from the rolls h h2 and parallel to its path of movement therefrom. The weight of the roll and its telescope connection with the support fr is suflicient to maintain properfriction upon the sheet to press it down upon the table D when the feed-gage CZ is removed from thereunder, and it will be noticed IOO IOS

that while the paper may bc fed from the rolls b' Ui beneath the roll r with but little friction, rotating said roll, the paper cannot be moved at right angles to said roll unless positive force be used, such as the movement of the feed-gage d. A skeleton frame rg0 is secured to the rod lif* and upwardly curved at its ends, the .feed-gage as it passes under said framelifting it, so that the gage can move easily beneath the roll 'r The leading edge of the sheet as it passes under the roll r6 moves under a detent t, Fig. I0, and against a stop-gage f', shown as a thin plate adjustably mounted on an arm 2, depending from the support r/S, the detent 'preventing backward movement of the sheet. The arm t2 is pivotally mounted and is automatically returned to vertical position by a spring S40, secured at one end to a pin t3 on the arm and at its other end to a pin t1 on a sleeve held in fixed position on the support g3 by a set-screw The sleeve is reduced and extended in tubular form at one end to form a bearing t7 for the arm t2, retained in place by a collar s, and a second bearingt9 is formed at the other end of the sleeve for the arm tw, which carries the detent. rIhe arm t1@ is centered by a spring 50, similarly to the arm t2, and a collar l2 retains it on its bearing. A platev tlg is adjustably secured to the arm tm by clamp-screws t, said plate having the detent t pivoted thereon at t, the said detent having a stop tl" on it to prevent undue movement by a spring .50. The stopgage t is also adjustably mounted on its arm t2 by means of set-screws if", so that the detent and stop-gage can be adjusted for wear, in order that they will always assume -the proper position relative to the table.

It is sometimes found desirable to supplement the action of the Iiexible downhold herein described by a roll, as 96, mounted on an arm 97, secured to the rod c' (see Fig. 2) near the inner end of the downhold, the roll rotating as the work comes from the primary scoring device, but presenting' its side to and preventing any retrograde movement of the work as the feed-gage is retracted from the secondary scoring device, the said roll 9G acting precisely as has been described for the roll r6. (Shown in Fig. 1I.)

Instead of using the waste-controlling devices shown in Figs. at, 5, and 6, we may use the devices shown in Figs. I3 and 17, wherein two rolls o and /12 are mounted in a yoke o2, pivoted at 1:3 on an arm e, the latter being cut out at 1:5 to receive a bearing-block e6 and form an abutment UX. By means of a setscrew v7 the block is clamped up against the shaft au to hold the arm e4 rigidly thereon, thus enabling the arm to be readily applied to or removed from the shaft without disturbing the latter.

The rolls e and e are adjusted to direct the waste by the set-screw e8, and then the rolls will operaie in conjunction with the betiroll AS.

Our invention is not restricted to the precise construction and arrangement herein shown, as the same may be altered or rearranged without departing from the spirit anu scope ot' our invention.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is-
