To all whom lt may concern:

Be it known that we, HENRY DE SMITH and CHARLES R. SEYMOUR, citizens of the United States, and residents of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Scoring-Machines, of

which the following is a specification.

This invention relates to machines for scoring paper-board, and particularly to that class of scoring machines or apparatus adapted for double scoring paperboard or similar material, and which are provided with two sets of scorers or scoring mechanism arranged to score the` paper-board in two directions (usually at right angles to each other) during a single passage of the same through the machine. A mechanism of this general type is disclosed in the prior patent to M. D. Knowlton #725,453, granted April 14, 1903, and the present invention is primarily an improvement upon that disclosed in said patent. In machines of this kind a suitable feed deviceis employed between the two sets of scorers for engaging a sheet or board after it has been operated upon bygthe first or primary scoring mechanism, and automatically feeding it to the next or secondary scoring mechanism, In the operation of such machines the sheets are fed oneat a time to the primary scoring mechanism and after emerging therefrom are engaged one at a time by a reciprocatory feeding device in the nature of a cross-feed operating crosswise of the first path of movement of the sheet, andare fed by said device to the. secondary scoring mechanism. In said machines it has also been customaryto employ means for automaticallyI controlling the passage of the sheets through the machine, for the purpose of preventing fouling or interference of two o1' more sheets when vthese are fed rapidly. In the machine illustrated in said Knowlton patent this automatic controlling means embodies as its main element'sheetsupporting means for receiving'that edge.

of each4 sheet which is to be actedv upon di'- rectly by the aforesaid'cross-feed device and supportlng said edge above the path of reci rocation of said device for a predetermined len th of time sufficient to assure the feeding Og the sheets one at a time only to the secondary scoring' mechanism.v Machines of the type shown in" said Knowlton patent have long been in regular commercial use, but in the actual use of said machines it l fs been found that their speed is limited. This is due toa number of causes, among which may be noted the construction and weight of the reciprocating feed device for transferring successive sheets to the secondary scoring mechanism, the length of the stroke of this device, and the manner in Which it coperates with the sheet-supporting means before -referred to. In addition to this the construction and modev of operation of the sheet-controlling means and the principle upon which its controlling action is based, which isI the timing of the operation of the sheet-supporting means fronrthe front edge of each entering sheet or board, have been such as to make accurate work at high speeds difiicult. It has however been found that it is practical to produce a machine of this general class capable of operation at high speed by prop? erly modifying the construction of the feed device before referred to, and reducing its weight, and decreasing its stroke, and especially by operating it from its center, or in such a manner that it is acted upon substantially equally at all points in its length; and that the capacity of the machine is much increased and the control of the operation of the sheety supporting and releasing means is greatly improved by the provision, in connection with the lighter, shortstroke, cross-feed device operated from the center as just described, of controlling means for the device for supporting and releasing successive sheets in which means the action of the main controlling element is determined by frictional contact and movement with the surface of the traveling sheet.

The machine constituting the subject matter of the present invention embodies the lfeatures of improvement just referred to and also others which will be hereinafter more specifically described.

In the accompanying drawings there is shown a machine illustrating, one embodiment of said invention, in Which.-

is an enlarged, substantially central vertical transverse section of a portion of the same illustrating the construct-ion and organization ofv the sheet-supporting and controlling means, the cross-feed device before referred to, and various coperative parts; Fig. 4 is anr enlarged transverse section of -a portion of the mechanism illustrating in detail the construction and various positions of the principal elements of the controlling mechanism forthe sheet-supporting means, the section. being taken in line 4-4, F ig; 5, looking in the direction of the arrows; Fig. 5 is a plan of-the same and of other portions of the controlling mechanism, the sheet-- supporting means, andthe cross-feed device, the same being illustrated on a smaller scale; Fig. 6 is a vertical longitudinal section, taken in line 6-6, Fig. 5, of portions of the cross-feed device and sheet-supporting means, showing the latter in position for supporting a sheet or board; Fig. 7 is a similar view of theserparts and an elevation of other parts of the controlling mechanism, etc., drawn to a smaller scale, illustrating the main elements of the cross-feed device and the sheet-supporting means in the positions occupied by them after the sheet or board has been released and has dropped into the path of the cross-feed device in readiness for feeding to the secondary scoring mechanism; Fig. 8 is an enlarged viewv partly in vertical transverse section and partly in elevation of portions of the sheet-supporting means, its controlling mechanism, and the cross-feed device, and illustrates particularly the manner in which the sheet-supporting means is moved to its effective and ineffective positions through the action of the controllinor mechanism and the cross-feed device, and Fig. 9 is a horizontal section and plan of a portion of the sane, the section being taken in line 9-9, Fig. S, looking in the direct-ion of the arrows.

Similar referencel characters designate like parts in all thentigures of the drawings.

1 represents the main frame-Work of the machine `and may be of any suitable form and construction for supporting the various working parts. Near one end of this frame and supported in suitable bearings is a main driver, 2, carrying a pulley, 3, for transmitting power to the principal operative parts. A suitable clutch device is illustrated at 4 for controlling the coupling and uncoupling of this driving means and the driven parts, of the machine. The clutch may be operated in any suitable manner, as for example through connections, such as 5 and 6, operated -by' a lever, 7, located at the opposite side of the machine in .position to be conveniently grasped by the operator. Two shafts, such as 8 and 9, arranged at right angles to each other and each carrying a bed-roll thereon forming parts of the primary and v'secondary scoring mechanisms respectively, are driven from the niain driving shaft 2 through suitable connections, as

is usual. '11m two scoring mechanisms, of which the bed-rolls 10 and 11 form parts, are also of the usual construction, they comprising the aforesaid bed-rolls and the usual scoring knives or cutters, 12 and 13, adapted to cooperate therewith, said knives being carried in the Welt-known manner by reversible bars, such as 14 and 15. In the rear of the primary scoring mechanism are also located, as is usual, a pair of feed-rolls, 1G and 1T, supported in suitable bearings vand adapted to engage the leading edge of the sheetas it is fed by the operator from the feed table, 18, through the primary scoring mechanism, said feed-rolls serving to feed the sheets successively through said primary scoring mechanism and onto the table 19 between the primary and secondary scoring mechanisms. These feed-rolls are connected and driven in any suitable or Well-known manner.

After the sheet has been scored in one direction and fed onto the table 19 it is engaged at the proper time by the reciprocating cross-feed device, which device operates, as is usual, in a. direction at right angles to the path of the first feed movement of the sheet. This cross-feed device, as here shown, is driven from the main driver in any suit-- able manner, as for example, by means of pulleys, 20 and 2l, connected by a belt, 22, the pulley 21 being secured to a relatively short shaft, 23, journaled in bearings at the under side of the machine in one end of the frame work and in a substantially central hanger, Q4, respectively, said shaft having at its inner end a crank.I 25, and suitable connections therefrom, including a pitman r0d.26, for imparting reciprocating movenient to a slidably supported rod 27 adjacent the under side of the table With which the cross-feed device proper is operatively connected. This cross-feed device is different in many respects from that disclosed in the aforesaid patent. It is similar, however, to that of said patent so far as the principal functions of such a device are concerned, that is to say, it is so constructed as to be capable of engaging the edge of the sheet substantially throughout the length of such edge, and of moving in a substantially straight line forward to feed a sheet to the secondary scoring mechanism, and then Withdraw out of the path of delivery of the next succeeding sheet.

The feed device proper is a relativel light plate, designated generally by 28. lit is considerablylighter than the corresponding feed device employed in the aforesaid patent and in the construction here shown is secured directly to a slide, 29, mounted for reciprocation in a corresponding guide, 30, formed by the walls of an opening eX- tending entirely through and substantially at the center of the table 19, and which slide in turn is adjustably connected with the reciprocating rod Q7 before referred to. It will be obvious t-hat by means of the crank and the described connections therefrom to the slide 29, the feed device 2S secured to said slide will be reciprocated back and forth on the table 19. This stroke of the feed device is relatively short and the speed of movement is relatively great as compared with that of the correspondingl feed device of the aforesaid patent; the. difference between the two being the difference between a high-speed and a low-speed feed device for ad 'ancing successive sheets to the. secondary scoring mechanisu'i. The present device also has the further great advantage over that of said patent of being operated directly and positively from its center so that'every point in the length of the work ing face of the feed device that comes in contact with the edge of a sheet advancesl at the same speed as every other throughout the working stroke, thus assuring positiv-e feeding and accurate positioning of the sheet without the use of heavy and slow-moving operating parts.

As the sheet is fed onto the intermediate table 19 from the primary scoring mechanism the edge of the sheet adjacent to the working edge of the cross-feed device 9.8 is intended to be received upon a sheet-support or trip-plate substantially parallel with the forward or working edge of said feed device 28 and to be supported by said trip-plate above the path of the feed device so as not. to be engaged by. the same until a certain predetermined time` at which time the tripplate is automatically shifted backward to permit the supported edge of the sheet to drop upon the table 19 and into the path of the cross-feed device 28. Mechanism for performing the operations of support-ingand releasing said edge of each successive sheet fed onto the table 19 is disclosed in the aforesaid patent. ln the present machine an improved mechanism for performing these operations constitutes one of the most important features of the invention and will now be described. l

For the purposeI of supporting one edge of each sheet and releasing itin the manuel' just referred to, sheet-supporting means, and automatic controlling means therefor are employed, in which a trip-plate is disposed just above the path of-,reciprocatonof the cross -feed device 28. This trip -plate is preferably a lightI strip, such as 32, slidably lsupported for movementto and fro in the same general direction as the feed device 28, on the under side of a fixed plate or crossbar, 33, secured to the lower lends of apair of arms, 34, depending from a rod, 35, above the table 19, which rod is supported at itsends in two adjusting slides, 3G and 37,

mounted for movement on parallel guiderods, 38 and `39,-suitably supported on the f 'ame-work ofthe machine'at opposite sides of the table 19. ln this construct-ion the vslidable frame formed by the parts 33, 84,

36 and 37 is adjust-able to differentpositherefor is stationary. Because of this it is possible to use a light trip-plate, readily shiftable to its supporting and releasing positions, and operate the same at high speed. rlhe trip-plate is preferably connected to the cross-'bar by pin-and-slot connections, as indicated at 40 and 41. the parts 40 being screws on the heads of which the trip-plate is supported and on the shoulder portions of which the AWalls ofthe slots are guided (see Figs. G and 7). The slots -ll are diagonal slots for a reason which will be hereinafter set forth. It will, of course, be understood that the trip-plate may be mounted for movement back and forth on its support-ing frame in any suitable manner so long as it .mechanism it is so formed as to be capable of cooperation with `one element of the automatic controlling means for governing the positions thereof. As this controlling mechanism is operated and controlled by the entering sheet or board, its construction and mode of operation will now be described in connection with the sheet-feeding mechanism.

' As before stated, one of the principal features of the invention is the actuation of the slieet-si1pporting"'iiiea11s proper, viz., the trip-plate, from a controlling element frictionally operated by engagement with the. surface Aof a sheet being fed into the machine. The construction and mode of operation of a Suitable controlling means for this purposeare illustrated particularly in Fig-s. 3, 4, S and S).- The main element of this controlling means is a `controller proper adapted to be actuated directly by frictional Contact ywith the surface of an entering` sheet. Preferably this contro-ller is a pivoted element, su-eh as the sector 4Q, secured to a rock-shaft, 43, mounted in a long bearing, 44, in a rock-.frame 45, on the lguide rodi-38 before described.- This rock-frame and the sector -l-Q andthe shaft 43 carried thereby are intended to have a limited movement toward and from the surface of a sheet entering the machine, this limited movement being controlled preferably by a strong coiled spring, suchas 4G, interposed between a cheek on an I-bo-lt, 47, journaled on the shaft 43, and a fixed stop, 48, carried at the rear end of the rod or shaft 38. This'I-bolt passes through the stop 48 :and

is adjustable up and down and is held inplace by means of suitable adjusting and check nuts, 49 and 50, this adjustment being for the purpose of locating the working face of the sector in proper relation with the periphery of the lower feed-roll 17 with which said sector coperates. This adjustment is for the purpose of taking care of sheets or boards of different thickness and assuring the proper coperation of the sector therewith.

'In addition to the movement of t-he sector just described, it also has another and main movement, z'. e., in the direction of the line of feed of the sheet, for the purpose of controlling the movements of the trip-plate. This movement is a swinging one about the a'Xis of the shaft 43, the limits of which movement vare indicated in Fig. .4. ln said figure it will be seen thatat its upper end t-he sector has a stop-face, 42', which coperates with a stop, 51, which is also preferably adjustable in order that the throw of the sector may be varied within limits. The stop 51 shown herein is a screw-threaded one which may be held in any desired adjusted position by means of a nut, 52. The sector 42 as here shown has a long curved slot, 53, therein to permit it to stradd'le. the shaft of the upper feed-roll 16 and coperate properlyT with the lower feed-roll. It also has a working face, 54, which is substantially an arc of a circle struck from the axis of the shaft 43, and a prolongation. 55, of said working face'which is not defined by an arc struck from said center, this prolongation being so shaped as not to come into feed relation with the surface of a board passing through the feed-rolls. The sector, 42, as illust-rated. also has an extensio-n o1" arm, 56, pivotally connectedat its free end to one end of a link, 57, as-by means of a headed pin, 58, engaging said link through a slot 60 therein (see Fig. 4) and carrying near. its point a washer, 59, held in place by a Cotter-pin, the connected end of the link being disposed between this washer and the adjacent cheek of a rounded bearing portion of the extension 56, as clearly shown in Fig. 5. At its opposite end said link 57 is pivotally connected to the free end of a rock-arm, 61, .secured to a rock-shaft, 62, mounted in suitable supports including a pair of bracket arms, 64, depending from a sleeve, 65, on the rod or shaft, 38, as shown in Figs. 5 and 7.' The construction and arrangement of these parts is such that the shaft 62 is rocked through the'linkage just described by the sector 42 whenever said sector swings about its axis in the shaft 43. Such a swinging movement will take place both on-the feeding of a sheet, such as-S, (see Fig. 4) into the machine, and on the release of the sector 42 from said sheet when the sheet in its advance emerges from the pass between the sector and thefeed-roll 17. In one case, thatis. on t-he feeding of the sheet, the sector, the operated linkage and the rock-shaft 62 move in o-ne direction, which is the direction determined by t-he advance of the sector in frictional Contact wit-h the sheet; while in the other case, that is, on the release ofv the sheet, all of lthese parts move in the opposite direction, which is the direction determined by the return stroke of the secto-r to its normal position. In Fig. 4. the dotted lines show the normal position of the sector and the full lines show the position of the sector when it is substantially at the end of its effective o-r forward movement in frictional cont-act with the sheet.

The controller or sector 42 constitu-tes the primary controlling element of the controlling mechanism for governing the movements of the trip-plate 32 before described. The connected linkage and rock-shaft constitute the movement-transmitting portion of this controlling mechanism. The `terminal member of the controlling mechanism is actuated by these movement-transmitting devices for governing the movements of the trip-plate. It is here shown as a finger, such as 66 carried at the lower endof a substantially Y-shaped swingingarm, 67, pivotally mounted ona pivot-pin, such as 69, carried in the ends of a pair of rock-arms, 68, secured to the rock-shaft 62 between the bracket arms 64 (see Figs. 3, 4, 5, `7 and S). This construction gives a long bearing for the depending finger 66 and also positions it very positively for operation in its predetermined path. It will be noticed that the upper portion of the member 67 is of relatively great length as compared with the depending linger 66, which in consequence is substantially rigid and has practically no movement-except about or lwith its pivot:4 69. Thevarious'positions which this finger 66 assumesl at the principal points in its cycle of operations are clearly shown in Figs. 4 and 8,to whichandto Figs. 5, 6, 7 and 9, reference willnow more particularly be made.

The normal position of the finger and its supporting rock-arms, that is, the position occupied by Vthese parts at the moment a sheet begins to advance the sector 42 by frictional contact therewith, is lclearly shown in full `lines in Fig. 3 and in dotted lines in Fig. 8.

4At this time the lower end of the finger is in At suchl time it will be seen that the forward side of the finger is in contact with a wall, 71, .of the trip-plate,v this being the front wall of an opening in which said finger 66 works'. The rear wall of this opening is preferably` tapered and is indicated at 72.

It` is intended to coperate with the rear side of t-he iin erA 66. It will be seen that the Wall 72 is o much greater length thanthe wall 71 and-,Win/the construction illustrated it will also be'noted that the opening 73 in the trip-plate is of dierent widths measured in the -direction of the length of the tripplate, the wider portion being at the rear of the trip-plate and its front wall being that indicated at 74. rlhe connecting wall be-l tween the walls 71 and 74 of the trip-plate opening 73 -is designated by 75.

lVith the parts in the posit-ions just described, when a sheet enters the pass between the feed- rolls 16 and 17, and, by frictional engagement with the surfacev 54 of the sector` 42 swings the latter from the dotted line position shown in Fig. 4l toward the full line position in said view, the finger 66, then in engagementwith the wall 7'1 of the trip-plate, contacts at its upper side with a stop-face 70 in fixed relation with the rock-shaft 62 and is swung by the rockarms 68 on said'shaftfrom the dotted line position shown inFig. 8 toward the full line position in said view,. which posit-ion it reaches when the sector arrives at a predetermined point in its advance with the sheet. The sectorthroughout its further movement in contact with the sheet holds these parts, including the finger 66,l in the full line position shown in Figs. 8 and 9, that is to say, it holds the trip-plate, 32, which has been advanced to the forward limit of its working stroke by this movement of the sector, in position for receiving and supporting one ed'ge`of the sheet advancing from the primary scoring` mechanism. The trip-plate will remain in this po! sition and will be held there positively because of the frictional contact of the sector with the sheet until the sheet passes beyond the feed- rolls 16 and 17. It should be noted here that as the trip-plate reaches the limit of its forward or working stroke, where it is in position for supporting` an advancing sheet, the wall 71 passes beyond the edge of the actuating finger 66 and the latter enters the wide part of the opening 73 opposite the wall 74, as shown in Figs. 8 and 9. At this time the sheet just fed into position for delivery to the secondary scoring mechanism is supported at its edge onl the tripplate 32. On its passage beyond the feedrolIs theL return movement of the trip-plate controlling means to its normal position will be -n. i The sector 42, the connected linkage, and all other parts of the controlling means, including the linger 66, will return under gravity togtheir normal positions, the finger 66 dropping into contact with the table 19 as indicated by the dotand-dash lines in Fig. 8. The linger 66 will then be, as just stated, in contact with the table 19 andwill also be. in position to be operated upon by .the reciprocating feed device 27. This feed device is intended in the present construction to coperate at its right-hand or forward end with the .depending linger 66. when the feed device is at the proper point in itsmovement, for the purpose of returning said nfinger to its normal position, that is, from they position shown by dot-and-dash lines in Fig. 8 tothe position shown by dotted lines in the same View'. In order to do this said feed device, in the resent machine; has at its extreme rightand end an vactuator or cam face of considerable length in the direction of movement of said feed device, this cam being indicated at 76. Itis so positioned that on the rearward or return stroke of the feed devicethis can face comes into contact with-the forward side of the lower end of the depending finger .66 and, with a gradual movement, but nevertheless quickly, returns said linger lt0 its normal position shown in dotted lines in Figs. 8 and 9. At the same time it'causes the engaged trip-plate to be shifted to release the last sheet fed through the machine and permits said sheet to drop .down onto the table'19 into the path of the feed device, for delivery to the secondary scoringI mechanism on the next forward stroke of said feed"device. This releasing movement or backward stroke ,of the trip-plate is due to the engagement of the depending finger 66 with the rear wall 72 of the opening 73 in the trip-plate, during said return movement of the finger, which acts to positively shift said lplate backwardly with a diagonal movement to its sheet releasing position. At the end of this movement the trip-plate is restored to its normal dotted line position shown in l8 and 9 and the finger 66 is in the narrow part of the opening in the trip-plate. a

Assoon as the feed device reaches the limit of its rearward stroke. by which time the finger 66 will be in its normal dotted line position as shown in said views and the trip-plate will have released the board supported by it. said feed device will be in readiness to feed said board to the secondary scoring mechanism, which feed movementwill thereupon be l'nought about by such forward movement of the feed device. The stroke of the reciprocating feed device 27 being a relatively short one, the board supported on the table will be quickly delivered to the secondary scoring and feed-Y ing mechanism and said board will be passed through 4them and onto the delivery side of the machine in the usual manner.

It will be noted that the cross-bar 33 supporting the trip-plate 32 is provided with an under-cut roove 33 which, with the trip-plate in a vanced position as shown in Fig. v6, forms with said trip-plate a threewalled guide which performs the function of properly locating. the edge of the sheet in its travel along the trip-plate and also prevents buckling of .the sheet- Most of the other yfeatures of the machine are or may be of well-known construction and 4the operation of them will be understood Without referring to .them in detail.
