To all whom it may concern."

Be it known that we, CHARLES R. SEYMOUR andO'rTO M. H0011, citizens of the United States, and residents of Rochester, in the county of Monroe'and State of New York, have inventedcertain new and useful limprovements in Machines for; Operating upon Webs of Material, of which the following is a specification. c

This. invention relates to machines for receiving a web of material and performing certain operations thereupon, such as cutting the same into predetermined lengths and trimming and creasing the Web of material or the blanks cut therefrom.

The object of the invention is to provide a machine of this type which is especially designed for receiving aweb of single-faced or double-faced corrugated board, and to cut the faced corriigated board into blanks or portions'of predetermined length, and then to trim the edge portions of the blanks so formecL'and if desirable',.provid e the blanks with the proper number of bending creases. These operations are performed in proper sequence by mechanism. the parts of which are designed in a novel manner and, are so related that they are automatically operated in timed relation. For this purpose, Various auxiliary devices are associated with the main machine, which auxiliary devices will he hereinafter described in detail in conjunction with the description of the main parts of the machine.

p The improved machine disclosed herein was designed especially for receiving singlefaced or double-faced corrugated board manufactured upon amachine constructed for the purpose, but not herein illustrated.

The present machine is designed to be located at the rear of the above-mentioned machine for manufacturing the lined or fared corrugated board, and when used in conjunction therewith, constitutes inefl'ect, a single machine. The rear portion of such machine, or; in other words, the mechanism which constitutes the s11bject-matter of the nrcscnt application may be used for operat ing upon other materials than faced corrulav itself or in combination withinachines other than the type above mentioned. The int-ward portion of the machine formsthe ated board. and. therefore, it may be used subject-matter of a separate application and has associated therewith the necessary mechanism for manufacturing the faced corrugatedboard and delivering the same to the feed end of the portion of the machine forming the subject-1natter of this applicat1on. The portion of the machine herein dlsclosed has associated therewith the mechanism for cutting the faced corrugated board into predetermined lengths and the mechanism necessary for trimming the "cut lengths and providing them with bending creases. llthoughthe rear portion of the machine herein disclosed is not limited to the treatment of faced corrugated board, the following description will, refer throughout to faced corrugated board as the treated material, for

'the sake of convenience.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a longitudinal vertical section through the central portion of the machine,-

ill"

stated, .the faced corrugated board dis-- charged from the forward portion of the machine not herein shown is gripped. by these rolls and fed to the present machine. The four pairs of rolls just mentioned may, therefore, be more properly termed pull rolls, as'they pull the material from the rear end of the machine for manufacturing the faced corrugated board and feed the same to the present machine.

The top rolls of the first three pairs are made adjustable toward and away from the lower rolls of such pairs by mounting the journals of the same in' 'bearing boxes 5.

(Fig. 3) capable of vertical sliding movements in the side frames of this part ofthe machine. The lower roll of each pair is mounted in stationary bearing boxes 6 over which the bearing boxes 5 are yieldingly supported by means of coil springs 7. It will be understood that there is an upper sliding box 5 at each side of the machine for each upper roll ofthe first three pairs and a lowerbox 6 at each side of the machinefor each of the lower rolls of the first three pairs, and that a spring 7 serves to support each upper box 5 upon the lower box 6. All of the upper boxes 5 are provided with bosses 8, each of which is internally threaded to receive a rotatable screw shaft '9. Each of the screw shafts 9 is rotatably mounted in and extends upwardly through a bearing bracket 10 mounted upon the corresponding side frame, and above such bracket each screw shaft is provided with a beveled gear 11. The beveled gears 11 of each pair are rotated from a transverse shaft 12 carrying two beveled pinions 13 to mesh with the two beveled gears 11 of each pair. There are, therefore, three transverse shafts 12, each of which carries two beveled pinions 13 for rotating the beveled gear 11 at each end of one of the rolls. Each of the-transverse shafts 12 is provided with a hand wheel 14, by means of which such shaft may be rotated to adjust the position of the corresponding upper roll toward and away from the underlying bottom roll. It will be obvious that the turning of any one of the shafts '12 will'simultaneousiy rotate the screw shafts 9 at the opposite ends of the corresponding upper feed refit to raise or lower the two boxes 5 in which such roll is mounted. The springs 7 serve to hold the upper rolls the proper distance away from the lower rolls and when the upper rolls are adjusted toward the lower rolls, they are moved against the tension of the springs 7. The adjusting mechanism just described is utilized to space the upper roll of each pair the proper distance from the corresponding lower roll to'fecd the faced corrugated board withoutcrushing the same.

It will be noted that the top roll 1 of the fourth pair of rolls is not adjustable by the same type of mechanism as that just described. The top roll 4 is mounted in upper sliding boxes 5 the same as the other top rolls, and the lower roll 4: is mounted in boxes 6 similar to the boxes 6 employed for the other lower rolls, and the upper boxes 5 are supportedon the lower boxes 6 by means of springs 7, just. as in the case of the first three pairs of rolls. Each of the top boxes 5, however, of the top roll 4 receives the threaded extremity of an arm 15, which extremity is locked to the box 5 by means of a lock nut 16. On each of the side frames is mounted a bracket 17 to which the extremity of a link 18 is pivoted.

-Each of the arms 15 is pivoted to the midportion of the corresponding link 18, as

shown at 19. The two links 18 are swung upon the brackets 17 to raise and lower the upper roll 4 by means of a lever 20 disposed at one side of the machine and rigidly so cured to a rock shaft 21. The rock shaft 21 at each side of the machine carries a rock arm 22 connected by means of a short link 23 to the extremity of the corresponding link 18. The lever 20 has connected thereto, a chain or cord 24 (Fig. 1) which may extend to an operators station at the front portion of the machine. In the normal position of the parts, the toggles constituted by the arms 22 and links 23 are straight, in which position the arms 22 abut against set screws 25. In this position of the parts, the top roll 4; is in its raised osition and is spaced from the correspond ing lower roll 4. The set screw 25, therefore, determines the spacing between these rolls. In the normal 'position of the rolls +1 of the fourth pair, they pinch the faced corru atedboard slightly and assist the first t ree pairs of rolls in feeding the same forward. As above stated, the extent of this pinching action .may be regulated in the case of the first three pairs of rolls by turning the hand wheels 14-. When these wheels are turned in one direction, the up per boxes 5 of the top rolls of the first thrcc pairs will be lifted by the springs 7, and when turned in the opposite direction, the screw shafts 9 will force the top boxes 5 downwardly against the tension of the springs 7. The space between the rolls of hatchet the fourth pair is adjusted to conform with the space between the rolls of the other.

pairs by turning the set screw 25. llf, for any reason, there may be a break in the through the machine, the lever is actuated to depress the top roll 4 and bring it into contact with the corresponding lower roll 4. It may also be desirable to do this in the event that the faced corrugated board 7 passing between the feed or pull rolls is comprises a Vertically reciprocatin of less than normal thickness, as may be the case if the material for forming the corrugated filler gives out, in which event, the web would not be properly fed forward by the pull rolls. By actuating the lever 20, the top roll 4 may be quickly brought into closer relation with the correspondlng bottom roll to compensate for the reduction in thickness of the web, and, therefore, the web will be fed forward and will not clog the machine. When the pull upon the lever 20 is released, the upper roll 4 will return to its normal position, due to the rovision of the springs 7 which support t e' upper boxes of the top roll 4.

After the faced corrugated board leaves the pull or feed rolls, it is caused to pass between a pair "of shear blades, the purpose of which is to cut the web transversely into predetermined lengths. of the shear mechanism is located the mechanism for trimming the web and providing the same with the necessary creases and to the rear of this creasing and trimming mechanism is positioned a trip device adapted to be engaged by the forward edge of the web to trip the shear mechanism and thus permit actuation of the same to per form a cutting operation upon the web. The shear mechanlsm thus constitutes that portion of the machine through which the web next passes after leavin the feed or pull rolls. The shear mec anism will, therefore, now be described.

Referring particularly to Figs. 1 and 3, it will be seen that the shear mechanism knife bar 26 extending transversely of t e machine and supported at its extremities in vertically movable slides, one of which is shown at 27 in Fig.- 3. The movable slides 27 are, in turn, mounted to reciprocate in side housings, one of which is shown at 28. Each extremity of the vertically reciprocating knife bar 26 is connected ,at 29 to a link 30, which, in turn, is pivoted at 31 to the extremity of the actuating lever It will be understood that there is one of these actuating levers 32 at each side of the machine. as shown in Fig. 2. Each of the levers 32 is pivoted at 33 to a portion of the shear frame. As shown in Fig. 2, there is a shear frame 34 at each side of To the rear the machine, and these frames are connected by means of a transverse girder 35. Each frame 34 has associated therewith the housing 28, above described, in which the movable knife bar reciprocates.

The lower knife bar is shown at 36 and is mounted at its extremities in the shearframes 34. The upper knife bar 26 carries the upper knife blade 37, and the lower knife bar 36 carries the lower knife blade 38, the two blades being properly positioned to cut the web transversely when the upper knife bar descends.

The two shear frames 34 and the con necting girder 35 are mounted to reciprocate as a unitlongitudinally of the machine on guides 39 formed on the bed of the machine. The mechanism for vertically reciprocating the upper knife bar is also utilized to reciprocate the shear frames in order to cause the upper and lower knife bars to travel with the web of material While the latter is being cut. This is accomplished by connecting the ends of the actuating levers 32 remote from the knife bars to "a crank shaft, the rotation of which causes oscillation of the levers 32 about their pivotal connections 33 as well as bodily longitudinal movementthereof. The crank shaft for accomplishingthis is shown at 40. At each end, the crank shaft 40 is provided with a crank arm 41 pivoted to' the extremity of the adjacent lever 32, as shown at 42. It is obvious that rotation of the crank shaft 40 will oscillate the levers32a-bout their pivotal connections 33, and hence reciprocate the upper knife bar in a vertical direction. As the levers 32 are pivoted at 33 to the shear frames, the rotation of the crank shaft will also impart a horizontal reciprocating motion to the shear frames. lft will be noted from Fig. 3 that when the crank pins .42 rotate from the positionshown in Fig. 3 in an anti-clockwise direction, the shear frames, together with the upper and lower knife bars, will move in the same direction that theweb of material is moving, and about the time the shear frames attain their maximum speed and are moving at about the same s eed as the-web of 1115 material, the cutting action will take place. This is due to the fact that the cutting action takes place when the crank pins 42 are at approximately their highest points, and at this time also the shear frames are moving 39 tric solenoidcircuit inwhich a solenoid, when actuated, permits engagement of the members of a clutch, which latter controls the rotation of the crank shaft 40.

The clutch just referred to for controlling the rotation of the crank shaft 40 is shown in Fig. 2, the member 44 of which is loosely mounted upon a clutch shaft 45,, and the member 46 of which is keyed thereto. The

member 44 of the clutch may assume the shape of ,a pulley, so that a belt passing thereover will serve to drive the same. As

will hereinafter appear, the pulley or clutch 44 are in engagement, ,it is, t-herefore, ob-

vious that the crank shaft will rotate to actuate the shear mechanism. Means is provided for normally holdingthe clutch members 46 and 44 out of engagement with Y each other, but when such means is tripped or released, the crank shaftis allowed to make one revolution. This means comprises the mechanism now to be described.

Mounted upon the crank shaft 40 is a cam .51 (Fig. l0), the cam surface of which is formed upon one of the lateral sides of the cam. Upon this cam surface rides a cam roller 52 carried by a bracket 53, which is mounted to swing about the axis of a stub shaft 54. Mounted to swing about the axis of the same stub shaft 54 is a second bracket 55,

to the extremity of which is pivoted a pawl 56 which normally engages-a shoulder 57 formed on the bracket 53. It will be understood that the two brackets 53 and swing about the axis of the stub shaft 54 indeendentl of each other, but are normally eld in t e relative positions shown in Fig.

10 by the pawl 56. Mounted to oscillate 55 unita'rily with the bracket 55 is a rock arm 58 which is connected by means of a link 59 to a yoke 60, which, as' will be noted from Fig. 2, acts directly upon the clutch member 46 to slide the same upon the clutch 55 shaft 45. lhe arrangement of the parts is such that the clutch spring 47 tends to engage the clutch members 44 and 46, but the pawl 56 just described holds the clutch memer 46 in itsinoperative position through 50 the intermediary of the bracket 55, the rock arm 58, the link 59 and the clutch yoke 60. It is obvious, however, that if the pawl 56 were tripped, that is, if it were moved from engagement with the shoulder 57, the bracket 55 would be allowed to move inwardly pawl 56 rides over the to 57. When the high-part o the cam 51 again toward the cam 51, and hence the clutch spring 47 would be permitted to engage the clutch .members. Means is, therefore, provided for tripping the clutch in this man- It is accomplished by means of an electric sole noid, shown at 61, in Fig. 10. When energized, this solenoid attracts the core or armature 62 and serves to swing a link 63 upwardly about its pivotal connection 64. Connecting the mid-portion of the link' 63 with the pawl 56 is a link 65. lVhen the solenoid is energized, 'thelink 65 raises until the extremity .of a slot 66 formed therein engages a pin 67 carried by the pawl 56. The pawl is, therefore, lifted and the bracket 55 is permitted to swing inwardly toward the cam 51, thus permitting the clutch member 46 to engage with the clutch member 44, as above described.

The link 63 has pivoted thereto, a swivel block 68, through which passes a rod 69 pivotally supported at its upper end, as shown at 70, to a stationary part of the machine. Two coil springs 71 are associated with the rod 69 in such a manner as to yieldingly check the movements of the links 63 and avoid shock. These springs 71, therefore, act as buffer springs.

After the pawl 56 is tripped and the crank shaft 40 is set in motion by the engagement of the clutchmembers 44 and 46, the cam 51 secured to the cam shaft, of course, rotates and brings a-low portion of the cam adjacent the cam roller 52. The bracket 53 is then permitted to move inwardly a sufiicient distance to allow the pawl 56 to again drop behind the shoulder 57, i being understood that when the pawl 56 is first tripped and the bracket 55 moves toward the cam 51, the

of the shoulder engages with the roller 52, the bracket 53 is swung 'backwardly to its original position, and as the pawl 56 now engages behind the shoulder 57, the bracket 55 is also returned to its original position. 'The restoration of the parts in this manner to their original position disengages the clutch members 44 and 46.

As above stated, the electric solenoid 61 is controlled from the heet trip 43, which, in turn, is actuated by the front edge of the web of material. The operation of the shear mechanism is, therefore, automatic. It may -ble of engaging the link 63 to move the same upwardly when the rod 73 is moved to the all) naianea left in 19. The link 63, may, therefore,

be moved upwardly by actuating the rod 73- mechanism may be tripped by hand by actu- :ating the rod 73.

It will be noted from Fig. 19 that before the clutch mechanism is tripped, the high portion of the cam 51 engages with the roller After the clutch mechanism is tripped, the crank shaft rotates until the high portion of the cam 51 again engages the roller 59., at which time the clutch members are disengaged. The crank shaft 40, therefore, makes one complete revolution during which the shear frames are moved forwardly and returned to their'original positions and during which the upper knife bar descends to cut the web, and then returns to its raised position.

ln order to prevent unintentional operation of the trip mechanism when working about the machine, a link 75 (Fig. 19) is provided having a slot 76 in its end portion in which a pin 77 carried by the bracket engages. The pin77 normall occupies sucha position in the slot'l'fi that t e link 75 does not enterfere with the movements of the bracket 55. 1f the link 75 i moved to the left, however, in Fig. 10, the right-hand extremity of the slot 7 6 will engage with-th pin 77 and revent movement of'the bracket 55, even if t e pawl 56 is tripped. The link 75 may be so moved to the left and locked in such position by means of a hand lever disposed at the side of the machine, or at any other point where it may be conveniently actuated. -As shown in Figs. 9 and 10, the solenoid 61 is electrically connected to the sheet-actuated trip 43. -As shown in the drawings, this sheet trip is disposed near the rear end of the machine and lies in the path of movement of the web. In some instances, it may be more desirable to use two sheet trips than one, and, therefore,two of such sheet trips have been illustrated in the drawings. Their relation with respect to each other is best shown in Fig. 7, from which it will be noted that they are arranged to be simultaneously engaged by theforward edge of the 'webof material. As shown in Figs. 8

- and 9, each sheet trip 43 comprises a casing or framework 7 8, which is adjustable longitudinally of .the machine upon a rod 79. turning the thumb wheel 80, the casing 78 may be shifted until it is brought to the proper position as shown by the calibrations 81 on the rod 7 9 and the pointer 82 carried by the casing and cooperating with the calr brations. The position ofthe sheet trip from the shear mechanism, of course, determines the length of the blanlrs cut from the web.

Mounted to rock in the casing 78 use transversely extending shaft 88 carrying at each end an upstanding arm 84:. The upper the arms 84 are swung' backwardly and the ends of the arms 84 are conneeted'by a transversely extending sheet engaging plate 85 arranged to be engaged b the front edge of the web of material. When so engaged,

shaft 83 is, therefore, oscillated. The oscillation of the shaft 83 serves to shift "a rock arm '86, to the upper end of which is pivoted a awl 87. The pawl 87 normally engages ehind a tooth 88- formed on the flange 89 of a sleeve 90, said sleeve being loosely mounted upon the shaft 83. When the pawl 87 moves forwardly with the arm 86, it, therefore, turns the sleeve 90 upon the shaft 83, but this movement is in opposition to the action of two coil springs 91 connected to the rear portion of the casing and to two depending

arms

92 and 93, the arm 92 being carried by the sleeve 90, and the arm 93 being a depending portion of the arm 86 which is rigidly attached to the shaft 83. The sleeve 90 is rotated sufficiently far by the pawl 87 to bring two oppositely disposed contact shoes 94 into engagement with corresponding electric contacts 95. After this contact is made, an upwardly projecting arm 87 associated with the pawl 87 strikes an abutment 98 and serves to lift the pawl 87 out of engagement with the tooth 88. (The of the coil springs 91 then returns the sleeve 90 to its original position and the electrical contacts between the parts 94: and 95 are broken. The arms 84 continue to-swing downwardly to such an angle that the web passes over the same, and when the blank 109 out from the web has passed completely over said arms, they are returned by the other spring 91 to their original upright position in readiness to be en aged by the forward edge of the next blanh.

The return movement of the sleeve 90 is yieldingly checked by means of a coil spring 97 coax ally disposed on a pin 98. A projection 99 associated with the sleeve 90 engages the pin 98 near the end of the return move-' 119 ment of the sleeve, and as the pin 98 is yieldingly held in the position shown in the drawings, the return movement of the sleeve 99 is yieldingly checked.

Tn the normal position of the parts, the 1115 contact shoes 9d are normally out of engagement with the contacts 95, as best shown in Fig. 9. These shoes are mounted to rotate unitarily with the sleeve 99, so that rotation of said sleeve brings each contact shoe 9A 120 into engagement with the corresponding contact The contacts 95 are carried by arms 190, to which the electric current is conducted from binding posts 191. The electrio wires from the solenoid 81 are connected the tact 99. ran

When two sheet trips arefiemployed, both of them may be connected in the same electric circuit, the latter being soarranged that the actuation of either trip will operate the solenoid. The manner of electrically connecting the sheet trips with the solenoid is diagrammatically illustrated in Figs. 9 and 10.

After passing through the shearmechanism, the web passes through the slitting and creasing mechanism, best shown in Figs.

1, 4 and 5. The slitting and creasing mechanism' comprises two pairs of mandrels or shafts, upon which cooperating cutting disks or knives and creasing blades are positioned.- These shafts are arranged one above the other in a vertical row, and means is provided for shifting the position of all of the shafts as a unit to bring either pair of shafts into such position that the web will pass through or between the cutting and creasing blades thereon. In this way, while one pair of shafts with the cutting 'and creasing blades thereon are operating upon the web of material, the. cutting and creasing blades onbthe other pair may be set for the next 10 e The shafts above referred to, upon which the creasing and cutting blades are mounted, are shown at 102, 103, 104 and 105. All of these shafts are mounted in vertically slid able side housings shown at 106 and 107.

The housings 106 and 107 are mounted to slide in frames 108 and 109, respectively, each of these frames being provided with guides 110, upon which thehousings slide.

Each of the housings 106 and 107 has associated therewith a rack 111, the teeth of which mesh with'the teeth of a pinion 112 mounted upon each end of a transversely extending shaft 113. The shaft 113 is mounted in the frames 108 and 109 and may be rotated by means of a crank applied to its extremity 114 (Fig. 2); When this shaft is rotated, it is obvious that the housings 106 and 107 will be raised and lowered in the side frames 108 and 109. 'In order to facilitatamovement of the housings 106 .and 107, the counter-weight 115 is provided at each side of, the machine mounted upon the end of alever 116, which is pivoted at amid point particularly Fig. 1)

117 to the frame of the machine. The free end of each lever 116 is connected by means of a link 118 to the base of the corresponding housing. At one side of the machine, one of the links 118 is pivoted to the housing 107,

and at the other side of the machine, a similar link is pivoted to the housing 106 (see The counter-weights 115 counter-balance a portion of the weight of the housings 106 and 107 and the parts carried thereby.

The shafts 102 and 103 constitute the up per pair ofcooperating shafts and the 'shafts104 and 105 constitute the lower pair of cooperating shafts. v As best shown in Fig. 5, the upper pair of shafts carry the desired number of cooperating knife disks 119 to slit and trim the'web and also the desired number of cooperating creasing blades 106 and 107 are in their lowermost position,

the upper pair of shafts are in position to have the web fed therebetween and, therefore, the knives and creasing blades upon the upper pair of shafts will operate upon the web of material. The housings may be held in this position by means of a pin 121 mounted at each side of the machine in the frames 108 and 109. The extremity of the pins 121-engages in openings 122 of the housings to lock the same in position and before the housings can be moved, it is obvious that the pins 121 must first be withdrawn against the tension of'coil springs 123 which normally hold the pins in their operative position. While the upper pair of shafts and the creasing and slitting blades thereon are being used to operate upon the web, the creasing and slitting blades upon the .lower pair of shafts may be properly positioned for the next job. When the next job is started, the housings are raised by the mechanism above described to bring the lower pair of'shafts into operative position, and then the creasing and slitting blades upon the upper pair of shafts may be re-positioned, if desired. When the housings are in their raised position, the locking pins 121 are adapted to engage in openings 122 to support the housings in this position.

- The lower shaft 103 of the upper pair and the upper shaft 104 of the lower pair are mounted in bushings in the housings 106 and 107, but the upper shaft 102 of the upper pair and the lower shaft 105 of the lower pair are mounted in sliding bearing

boxes

124 and 125, respectively. It will be understood that there is an upper sliding bearing box 124 at each side ofthe machine for thetopmost shaft, and likewise a slidable of the two upper bearing boxes 124 has an internally threaded hub portion 126 to receive the extremity of a threaded screw shaft 127. There are two of these screw shafts, one being arranged at each side of the machine for eachupper bearing box 121.

, bearing box at each-side of the machine reiaoea of a beveled gear 129 driven from a beveled pinion 130, the twobeveled pinions 130 for driving the two'beveled gears 129 being mounted upon a transversely extending shaft 131, best shown'in Fig. 5. This shaft may be rotated any suitable manner, such, as by applying a crank to the extremity 132;

of the shaft. By rotating the shaft 131, it is obvious that the upperbearing boxes 124 will be raised'and loweredto ad ust the position ofthe shaft 102 with respect-to-the shaft 103. A similar arrangement of parts, comprising beveled gears 129. meshing with beveled pinions 130 mounted upon a transversely extending shaft 131.,serves to adjust the lowerbearing boxes 125 in the same manner as above described in connection with the upper boxes to vary the distance betweenthe shafts 104 and 105 of the lower pair'.- The shafts 131 maybe actuated by applying a crank to the 'extremlty 132' thereof. l

The position or spacing of the cutting or, slitting, and creasing blades "u on the shafts which carry them maybe facllitated by the provision of a scale 133, shown iii-Fig. 4. This scale'runs transversely of the machine and normally occupies theposition shown in. Fig. 4. ft is supported near each end by a bracket 134 pivotally mounted upon a rod 135-{which' is fixedly carried in'the adjacent housings, as shown. lEach bracket 134 is normally locked-to its plvot'al support 135 by means of a set screw 136, and,thereposition shown-in Fig.- 4. By loosening the set screws 136,however, the scale 133 may be raised or lowered to bring it adjacent to the blades of thellower shaft of the upper fair, or the upper shaft ofthe lower pair. fter the cutt ng and creasing blades are set on either of these two shafts, the blades on the coiiperating shaft may be set accordingly.

The lateral edge ortions trimmed from the web of material ythje trimming knives may be deflected downwardly by a so-called trim deflector 138, mounted" at each side of the machine. These deflectors direct the trimmed portion of the web downwardly toward the base of the machine. The trimmed portion of the web is then engaged by a lid" trips.

These" rollers are mounted upon pivoted arms 143 carried by brackets 144 mounted upon the frame of the discharge table and serve to .hold the web in contact with the discharge belts. The end rollers 142, of each series are positioned over the corresponding pulleys, over which the belts passand the intermediate rollers 142 are positioned over rollers 145 located below the discharge belts .and supported by brackets 146.

Each of sthese brackets or castings 141'- is carried by a rod 148 which runs longitudinally of the discharge table and' which is -.pivoted at its forward end to the frame of the discharge table, as shown 'at 149. The rear end of each. of the rods 148 is supported from a depending link 150.

' The arrangement of the gears for driving the various parts above described has yet to be considered. Running longitudinally of the machine at one side thereof is a shaft 151 (Fig. 2) carrying a beveled pinion 152 meshing with a crown'gear 153 secured to the face of the pulley44. Therotation of the pulley 44 by a belt passing thereover, therefore, serves to drive the shaft 151 and the rotation of this shaft n'iay be utilized to drive the other parts of the machine. i ls above stated, however, the machine disclosed herein is designed to be used at the rear of a machine for making faced corrugated board and the shaft 151 may. therefore, extend forwardly to such machine and be driven therefrom. In this instance, the shaft 151 will constitute a driving; shaft and will serve to drive the pulley 44 through the meshing gears 152 and 153. It is obvious that under these circumstances, the pulley 44 need not be driven by means of a belt passing thereover. I

The feed or pull rolls at the forward portion of the machine are driven from a shaft 154 which loosely carries a beveled gear 155 meshing with a beveled pinion 1156 upon the shaft 151. Aclutch 157 serves to connect or disconnect the gear 155 with the shaft 154- This clutch may-be operated by means of a pivoted lever 158 which, in turn, may be actuated by means of a rod 159 running to the side of the machine and actuable by a handle 160 (Fig. 2). The shaft 154 carries at its end remote from the gear 155, a pinion 161 which meshes with two gears 162. Each of these. gears is mounted upon. a shaft 163 which extends back to the drive side of the machine. At this side of the machine, each of the shafts 163 carries a pinion 164, whiclr'serves to drive a gear 165 mounted upon one of the shafts of each pair of pull rolls. 1t will be understood that the two pull rolls of each pair are geared together by two gears 165 and that as one of such gears of" each pair is driven by an adjacent pinion 164,'all of the feed rolls are positively driven.

Running parallel with the rear portion of the machine is a shaft 166 geared to the shaft 151 by means of the meshing gears 167 and 168 (Fig. 2). The shaft 166 carries a beveled pinion 169 meshing with a beveledgear 170, which is utilized tor driving the slitting and creasing shafts.- The gear 170 is loosely mounted upon a shaft 171 and may be operatively connected there to by clutch mechanism actuated by means of a pivoted lever 172, which, in turn, is operated by means of rod 173 running to the side of the machine where it carries a' handle 174. The shaft 171 at its end remote from the gear 170 carries a pinion 175 meshing with a gear 176. The gear 176, as shown in Fi 2 and 5 rotates integrally with a pinion 1 7, which is adapted to mesh with either the gear 178 mounted upon the extremity of the lower shaft of upper pair of slitting and creasing shafts or with the gear 179 mounted upon the lower shaft of the lower pair. When the four creasing and slitting shafts 102., 193, 104 and 105 are in their lowermost position, the gear 178 carried by the lower shaft of the upper pair meshes with the pinion 177, and, therefore, the upper pair of shafts are positively driven. The two shafts of each pair are intergeared by means of the meshing gears 180 carried by the ends the shafts remote from the gears 178 and $179. The

of gears 130 connect the two u urged toward the clutch member 46 and the lower pair of gears 180 connect the two lower shafts. When the four slitting and creasing shafts are in their raised position, the dri ing pinion 177 meshes with the gear 179 carried by the lower shaft of the lower pair, and, hence, the two lower shafts will be positively driven. By this arrangement of gearing, the'two slitting and creasing shafts which happen to be in operative position will be the two shafts which are 141 over which the discharge belts pass, and,

therefore, rotation of the the discharge belts.

As described above, the crank shaft 40 from which the shear mechanism is operated makes one revolution, and is then disconsect-ed from its driving mechanism by the disengagement of the clutch members 44 and 46, In order to insure a prompt stoppage of the crank shaft 40, when the clutch members and 46 are disengaged, theslidable clutch member 46 is caused to bear against friction brake mechanism to stop the rotation of the member 4-6 when it is disengaged from the clutch member 44. For this purpose, the clutch member 46 is provided with a flange 184 adapted to bear against the friction surshaft 183 actuates face 185 of two yieldingly-mounted slidable rods 186 and 3187. These rods are yieldingly means of the coil springs 188 and 189, but

' the inward movement of these rods is limited by the nuts it!) and 191 carried by the two reds, respectively. The friction surfaces 185 are, therefore, spaced from the flange 184 when the clutch members are in engagement, but when the clutch member 46 is thrown out of engagement with the clutch member 44, the flange 184 will engage with the friction surfaces 185 and the rotation of the shaft 45, and hcncethe crank shaft 40, will be immediately arrested.
