To all wlw/ft it /imj/ concor/i.

. .l .lle it known that l, Unitarios E. bm.-

uoi'n, citizen ol the United States, and res'b i dent ot ochestcr, in the county of Monroe parts being' broken away to show the construction; Fig. 2 is an enlarged plan partly and State oit New York, have invented certain ne f and useful lmprovements in Scor iagili/iachinos7 ol which the following` is a specilication.

ihis .invention .relates to machines for scoring paper-hoard, and particularly to machines ot that class known as doublescoring n'iachines, in which lsel'iarate sheets ol" lpaper-htnird are ted lirst through pri mary scoringv mechanism in one path and then through secondary scoring mechanism in a path usually at a right angle to such tiret moven'ient to score the sheet alongg,` lines pcrpendiciilar to lach other.

The present invention has ttor its principal object to provide a lmachine olf this class in which the movements of successive sheets .into and through the machine are positively controlled, and also to provide a machine ol this class capable of ollgieratjion at high speed.

Aln carryingv the invention into effect means are provided lor presenting successive sheets to the machine in such manner as to assure a positive cooperation oit all ot the elements that operate upon said sheet during its passage through the machine, timingi means beingl employed vfor preventingrv the delivery oitl a sheet from the first toed-table to thc primary scoring mechauism except, at a predetermined point in the cycle oit operations of the machine, which point in the machine ilh'lstrated herein is always the same lor cach cycle oit operations.

',ln general, an important object ot the invention is to provide a douhlescoring` machine in Vwhich all ot Vthe parts are so organized as to move in a certain predeteriifiined timing` in cooperation with one another and to present each sheet to the receiviupy end ot the machine at such a time that in its travel through the machine said ,sh-cet will lind the successive sub-mechanisms and elements ready to receive it and operate upon it without loss ot time and 'Without any interference olf a sheet travelineI in scribed and claimed and are illustrated in the accompai'iyinp,Y drawings, in whichm Figure l is an elevation of the machine looking trom the left-hand side thereof,

Similar relierence characters designate like parts in all, the ligures olf the drawings.

The douhle-scorinp,l machine shown herein is, or maj7 he. in many respects the same or substantially the same as correspondiupmachines in general use. It embodies among other parts oli well-known construction, a main l'rame 2; a feed-table trom which sheets are led into the machine; a right-hand end rage l, on said teed-tahle; primary scoringl mechanism 51 comprising,` the usual hed-roll (l and coijiperativ'e scoring` knives 'Tl a pair oit' leed-rolls 8, hy means o1 which successive sheets are Ateol :trom the primarv scoring niecnanism into position 'for deliver)7 one path through one oit the scoring' mechanisms with a sheet traveling' in another' path through the other scorlng mechanism.

( )ther features of the invention not herel to the seconda r v scoriniV mechanism; a lieedf table l), onto which said sheets are ted from the primary scoring mechanism; a reciprocatory jliecd device, l0, for 'feeding the sheets from said table 9 to the secondary scoring prises a pair of feed-rolls, such as 14 and 15,

' able bearings in the aforesaid slide-blocks .surface of the roll carried by it is always mechanism; and the secondary scoring mechanism 11, of similar construction and operation to that of the primary scoring mechanism. In connection with these parts suitable guides, stops, brushes, etc, are or may be employed as in the ordinary machine of this type.

All of the parts of the double-scoring machine shown herein may be operated from a suitable, main driver', which in this case is the shaft, 13, carrying` the bed-roll, 12, of the secondaryT scoring mechanism. From this shaft movement is intended to be transmitted through suitable driving connections both to the timing means for controlling the presentation of successive sheets to the primary scoring mechanism and also to means for feeding to the secondary scoring mechanism sheets delivered onto the table 9 from said primary scoring mechanism. The connections to the timing means and to said last mentioned feeding means, which in this case is the reciprocatory feed device, 10, may be any suitable for the purpose.

Considering first the timing means for presenting sheets to the primary scoring mechanism, this comprises a feed device and means for bringing it into feeding relation with successive sheets in a predetermined manner, the object being to cause each sheet to be delivered to the primary scoring mechanism and associated pair of feed-rolls 8 8 at the same point in each cycle of operations of the machine, in order that each sheet may always pass through the machine in an exact predetermined relation to all of the submechanisms and elements that coperate with it and are intended to act upon it. Here the timing means for feeding successive sheets into the machine preferably commounted so as to be capable of operating in such a manner as to open and close at the proper moments the pass between them to release or engage a sheet. In this construction the upper feed-roll is mounted on a long shaft, 16, extending transversely across the machine just above the delivery end of the feed-table 3, and the feed-roll 15 is mounted on another shaft, 17, parallel with the shaft 16 but located somewhat below the delivery end of said feed-table. The lower of these shafts is suitably mounted in bearings in such a manner that the top of the substantially in alinement with the upper surface of the feed-table 3. The upper shaft 16 and its roll are, however, mounted in a vertical reciprocatory frame formed in part by vertical slide-blocks, 1S, and in part by vertical links, 19, operatively7 connected with the shaft 16, which shaft is mounted in suitlS. VThe links 19 straddle the shaft 17 land have elongated slots Q0, the length of which is sufficient to provide for the necessary up and down movement of the upper timing feed-roll la and its shaft 16. Said upper feed-roll is preferably normally held down in feeding relation with the lower one by some suitable means-such, for example, as coiled springs 21, surrounding the stems, '122, connected with theA slide-blocks lS-in such a manner as to permit adjustment of the stem, slide-block and roll up and down as a whole, while also providing for an independent up and down movement of the roll and its shaft in said slide-block. The means for adjusting the up and down position of the feedroll, etc.. is preferably a pair of nuts, 23 and 2e, at the upper end of the stem 22, one being an adjusting-nut and the other a check-nut, as usual. The up and down movement of the roll lll resulting` from the up and down movement of the levers or links 19 is a relatively short one, it being, however, suflicient to permit a sheet in the pass between the feed-rolls 1e and 15 to be. out of feeding relation with the peripheries of said feedrolls at the proper time. The means for imparting vertical movement through the links 19 to the upper of these timing feed-rolls is illustrated herein as embodying a rock-shaft, 25, having' short rock-arms 26, connecting with the links 19 and a long rock-arm 2T, connecting with operating means for the rock-shaft. The short arms 26 are substantially horizontal and the long arm 27 substantially vertical in the construction illustrated, in. order that a substantially straightline up and down movement may be imparted to the upper roll 14.

As shown in Figs. 2, 4, and 5, the devices just described are operated by a long connecting' rod, 28, connected at one end with the arm 27 and at its opposite end extending to the rear of the machine and there connect-ing with a lever, 29,' mounted to swing back and forth substantially in the direction of the length of the machine and controlled in its movements by a cam-wheel, 30, mounted on a shaft. 31, connected, as by gearing. with the main driver 13. The connectiiig rod 28, as shown, is made of two sections connected by a turn-buckle, 32, for the purpose of making the necessary adjustments in the length of said rod. rilhe operating lever 29 to which said connecting rod is connected carries, preferably an antifriction roll, which makes contact with the surface of the cam-wheel 3() and is intermittently swung' back and forth at one point in the rotation of said cam-wheel by the cani surface Bt thereof. The same connections just described also serve in part as a means for operating an automatic stop-plate adjacent to and cooperative with the timing feed-rolls 1% and 15, for the purpose of preventing the presentation of a sheet to the primary scoring mechanism until the proper moment in llO the cycle of operations. This stopplate .may also be of any suitable typc and construction and may be ope ated iii any proper manner. lt is here shown as a. plate, 35, secured to vertical arms, 36, pivoted at their lower ends to horizontal rock-arms, 37, on the shaft 25, corresponding to, but of greater length than.` the short arms QG on said shaft.

by means of which the upper timing feedroll ll is moved upward to release a sheet. llVhen the shaft 25 is rocked it will be obvious that the up and down movement of the ends of the rock-arms 37 will be much greater than that of the arms 2G, and the stop-plate is intended to have a correspondingly greateiI up and down movement than the timing,` feed-roll lll. The extent of this movement will be clear by comparing Figs. d and 5, in the former of which the stopplate is down in position to permit the feeding` of a sheet into the machine by the feedrolls l-'land 115, then in feeding relation with such sheet, While in Fig. 5 said stop-plate is shown as up in the path of a sheet pushed forward on the feed-table and as out of feeding` relation with the rolls la and 15, the upper of which at such time is raised. The stop-plate, as here illustrated, is intended to slide up and down in contact with the forward end of that portion of the frame of the machine on which the feed-table 3 supported, this portion of the frame being' indicated at 3S, and the stop-plate and its carrier-arms 3G are shown as connected to the member 38 of the framework by suitable screws, 39, on the shanls of which the stopplate is intended to slide, it being slotted at d0 to permit this. lt Will be noted that by means of the operating connections just described the stop-plate and the timing feedrolls are brought into or out of position for the feeding of a sheet, or for preventing the feedingI of a sheet, at substantially the same moment, and also that this operation is controlled from the main driver through suitably timed connections. These operating connections are also intended to coperate in predetermined timing with the reciprocatory feed device l0, and indeed with all of the other operatively connected mechanisms and elements of the machine.

rilhe reciprocatory feed device l0 is in many respects substantially the same as that disclosed in another application, Serial No. TiJfLSQQ, tiled January 13, 1913. lt is preferably a light feed-plate having,l a short stroke to permit of operation at high` speed and it is disposed and operative to engage a sheet delivered onto the feed table 9 at one edge of said sheet and push the sheet to the secondary scoringl mechanism. lt is also adjustable for travel baci; and forth in different Z ii es correspondinp,q to the width of sheets fed. its in said prior application, it is carried by and adjustable on a slide mounted to reciprocate in a suitable way disposed 'substantially centrally of the feed table 9, the construction of all of these beingl preferably the same as in said prior application. In several. respects, however, this reciprocatory feed device or pusher 10 differs fro-ni that of said prior application and it operated in a manner entirely different from that of the corresponding device of the aforesaid application. Here it is formed. with a vertical rib, l2, for engaging the adjacent edge of a sheet, which rib is made relatively high to prevent possibility of the feed device passing under a warped or similarly distorted sheet and so failing,l to feed the same. The feed device here shown also has a foot or member, 4:1, j nojecting` forwardly from the base of the rib l2 a suiiicient distance to extend beneath the edge of a sheet being fed onto the `feed table 9 when the feed-device has reached the limit of its backward stroke. TWith the feed device thus constructed all possibility of the sheets goingeither under or over the same in the operation of the machine is avoided.

An important feature of the present machine is that the feed device l() is intended to be operated with a. variable movement for the purpose of enabling it to start gradually on its workingstroke without injury to the i surface of said sheet and without tending to buckle it. As soon, however, as said sheet is started to fia-rd the secondary scoring mechanism it is desirable that the speed of travel of the feed device l() be rapidly increased up to the point where it is moifing` at substantially the same rate of speed that the surfaces of the second pair of feed-rolls are traveling, this speed being,l reached, preferably, substantially at the moment that the edge of the ad fancing sheet enters the pass between the feed-rolls of the secondar y scorn ing mechanism. The object of this is to assure the presentation of the whole edge of a sheet to the rolls of the secondary scoring1 mechanism at the same instant and the proper straight-line feed of the sheet through said mechanism and out of the machine. The desired variable movement for rapidly increasing' the speed of its working; stroke, and a long dwell at the rear end of its stroke, may be obtained by suitable connections to the main driver 13, as, for example, through a connecting rod and crank-shaft operated by atrain of elliptical gears. Here the feed device l0 is operatively connected by a pitman, dt, with the crank, 46, of a crank-shaft, 45, mounted in suitable bearings at l? and .l-S near the rear end of the machine, said crank-shaft being in turn driven by a train of three elliptical gears, 49, and 5l, mounted respectively on shafts or studs, 31, 52, and 45, supported in an open frame 58, at the rear end of the machine. The shaft 3l which, as before pointed out, is the means for imparting movement to the timing feedrolls and the stop-plate, also carries in this case a spur-gear el, which is driven by a spur-pinion, 55, secured to a short shaft, 56, having also in fixed relation therewith a spur-gear 5T, meshing with a spur-pinion, 5S, on the main driver 13. From this main driver through the spur gearing just described movement is imparted to the shaft 31 and hence to the elliptical gears and the reciprocatory feed device l() operated thereby, and is also imparted in proper timing therewith to the upper timing feed-roll and stopplate associated with it. Provision is also made, as will be clear by referring to Figs. 2 and 3, for changing the speed of the machine to suit different kinds of work, by changing the connections between the shaft 3l and the driving shaft 13, this being accomplished by shifting differential gears one of which is the gear Said gear 54 is shown as carried by a sleeve, 59, having a substantially central circumferential groove for engagement in a well-known manner with the pins of a shifting lever, 60, by meansof which said gear and a second differential gear 54 on the same sleeve may be shifted back and forth into and out of driving connection with the shaft 18 by movement into and out of operative relation with the respective differential driving pinions and 55 in iXed relation with the spurgear 57.

The primary and secondary scoring mechanisms, including the feed-rolls and various other operative parts associated therewith, are or may be driven in usual manner from the main driver 13, so that all of the working parts of the double-scoring machine shown in the present application are operatively connected for movement through a certain predetermined cycle of operations in which the travel of each sheet through the machine is mechanically predetermined and controlled, the feed of each sheet being positive and the mechanisms being so timed and cooperating in such a manner that every sheet is started into the machine at the same point in the cycle of operations. The speed of operation of the various main parts just described and the timing relation are such that there is just time enough for the first scoring and feed rolls to advance one sheet from a position of rest on the feed-table 3 back of the stop-plate, to a position against theV usual stop-gage, 6l, on the feed-table 9, while the feed-plate l0 is advancing a preceding sheetA into the secondary sco-ring mechanism and is returning again to the end of its .back stroke; said feed plate being suficiently far advanced on its forward or feed stroke at the time the second sheet is being fed from the primary scoring mechanism to the second feed table 9 as not to catch said second sheet which is adapted to ride over the top of the feed plate without being acted on thereby. Thus in the operation of the machine the upper timing feedroll ll is lowered to feed a sheet in, the stopplate is also lowered below the level of the feed-table 8 to allow that sheet to be fed in, and the feed device l0 makes one complete stroke.y all in the same cycle and in predetermined timing in such a manner that a single sheet is fed through the machine at each stroke of said feed-device and it is impossible for two sheets to interfere with each other in the machine or for a sheet to fail to travel steadily in a predetermined manner through both the lirst and second scoring mechanisms.

In a machine of this type the scoring rolls may be operated at higher speed than in machines as heretofore constructed and increased capacity thus obtained.
