Be it known that I, GEORGE W. Swn'r, Jr., a citizen of the United States, residing at. Bordentown, in the county of Burlington and State of New Jersey, have invented certain new and useful Improvements in Feed Mechanism for Slotting and- Creasing Machines, of which the following is aspecificatlon. I

The object of this invention is to provide a machine which will most efficiently slot and crease material, su h as card board or. corrugated card, for the formation of boxes, cartons, or containers, therefrom, thesame' being a division of application Serial No. 200,698 filedNov-erfiber 7, 1917. 4

More definitely, the object is to provide an improved feed second pair of said dies and cutters; Fig. 20 is an end view feed rolls; Fig. 21 is a side elevation of the same; Figs; 22, 23 and 24 are respectively top, side and end views of the feeder rolls for the creaser shaft; Figs, 25 and26 are respectively' side and endviews-of an improved adjustable crank or eccentric for mechanism for feeding the feed table stock elevating arm;lFig. 27

isasection on line 27-27 of-Fig. 1; Fig.

of the invention comprises a v forward portion thereof extends a horizontal feed table comprising spaced channel irons ;5, between the upper while the said table by means of bolts 8.: Abovethe forw-ardmost portion of the said'table piled, from which position they are designed to be fed into the machine as will now-be described.

Suitably journaled in the channel iron side bars 5 adjacent to the front and rear ends of feed table 6 are the transverse shafts 79' and 86- carrying respectively the. spaced sprocket .WhQBlS 80, .80 and 87, 87 upon which are the-laterally inclined slots formed in the table 6 to receive the chains. An adjustable angle-iron side gage 6 is mounted upon the feed table 6 at the side towardwhichthe sprocket chains 8.8 incline, so that the feed bars 89, moving in their inclined path, continually urge thesuccessive blanks into gaging contact with gage 6 and insure the feed of the blanks to the machine in proper position; The tension of the sprocket chains 88 ,may' be maintained as desired by meansof idlers 90, carried upon the free 'ends of de pending pivotally mounted members 91.

The blank-feeding mechanism just de-' scribed is suitably geared to the slotting and creasing machine to permit the convenient adjustment and timing of the feed to correspond with the work' to be performed. I

' prefer to accomplish this result by the ed at 85 upon the frame 3 by which the gearcarried mechanism shown particularly in Figs.- 1, 3, 27 and 28 of the drawings inwhich a gear wheel 78 is adjustably mounted upon the shaft 79 by means of a disk 7 8' whichis fast uponthe shaft and isdeta'chably secured to gear 78 by means of-screw. bolts 82. Pins 83 project" laterally from gear 78 (at diametrically opposite points) in position to be engagedby a latch member 84 p ivotally mountis' held against movement whenfreedfrom the shaft 79. Gear 78 meshes with and is driven by .an idler pinion 77, which "is in turn driven by a pinion 20 on shaft 16 hereinafter referred to. The shaft 79 also has a hand-wheel 81 secured to it, by which the feed mechanism can be manually adjusted when the gear 78 is freed on sh'aft 79.

In adjusting the feed mechanism for a given size of box blank the machine is stopped with the first pair' of creasing members"(presently to be described) in a given osition, such for instance as that shown in ig. 2, and the latch member 84, is moved into engagement. with one of the pins 83, by thegear 7.8. Said gear. is then freed from its shaft 79 by unscrewing bolts 82,'as described and shaft 79 is revolved by means of the hand-wheel 81, until a feed bar 89, abuts against the rearmost edge of the desired blank resting upon the table 6 and having its forward-edge in the desired relationship with said first set of creasing members. The screw-bolts 82 are then tightened member 84 is disengaged from pin 83, after which each successive blank will be fed into the machine in'exactly the desired position. This feeding mechanism is covered by my divisional application Serial No. 27v ,550, filed February 17th, 1919.

Successive blanks are taken from the shelf 9 and placedupon feed table 6 over which they are carried by the feeding mechanism above described and presented to feed rolls 15 carried by transverse shafts 16, 16' (see Fig. 7). Said shafts are journaled in side frames 3 and 4, the upper shaft 16 carrying a pinion 17, at one end meshing with an idler pinion 18, substantially above it and rotatably carried by apin 19 secured to the frame 4,' while the lower of said shafts 16 has securedthereto the'pinion 20, meshing in turn with an idler pinion 21, revolvably carried' by a pin 22, secured to the frame 3.

As each blank approaches the feed rolls. 15 its forward edge is raised by the spaced arms. 95 mounted upon the rock shaft 96 and movable upwardly through spaced slots 97 in the feed table 6. The outer end of the shaft 96 carries a slotted crank-arm 98 to which is adjustably' journaled one end of a rod or pitman 99 having its other end Y j journaled upon an operating crank mounted upon a'suitably timed shaftof the machine.

to lock the gear 78 upon its shaft, and latch I prefer to construct this operating crank" in the form shown in Figs. 1, 25 and 26,-in which a segmental crank-arm 101, having a crank-pin-opening 100, is securely vbolted to one edge of the outer face of a removable and adjustable ring or collar 102,which is radially enlarged uponthe side 0 positearm 101 and suitably slotted, as at 1 3,104, to form an integral spring tongue 105, which constitutes part ofthe wall of the circular bore or opening of the ring or collar that fits the outer end of one of the machine shafts such as shaft 25. The enlarged portion of the. ring or'collar 102, is formed with 'a threaded radial opening 102 adjacent to the free end .of the spring tongue 105 to" receive a screw. bolt 106, which is adapted to engage tongue 105 and firmly clamp it against the surface of the shaft 25 for securing the ring or collar in the desired adjusted position thereon. The segmental arm 101 is so proportioned withreference to the diameter of the ringor collar 102 that the crank-pinopening 100 will be eccentric to the shaft 25 with the result that the rotation of shaft 25' will intermittently raise and lower the arms 95 for the purpose explained.

The blanks pass from feed rolls 15 to'the creasing members mounted upon the vertically spaced shafts 25, 25' journaled in bearings 26 carried by side frames 3 and 4. These shafts 25, 25 are provided with two and made up of gears 27, 27'

sets of intermeshing gears, one set secured to the shafts outside ofthe frames 3 and 4 on shaft and gears 28, 28 on shaft 25, while the other set is secured to the shafts inside of the side frames 3 and 4and comprises gears 37,37 upon the shaft 25 and the gears 38, 38 upon the shaft 25, The 'intermeshing gears outside of the side-frames are normally fixed upon their shafts, although it is preferred to providemeans. by which they can be relatively adjusted. The intermeshing gears insidegof the-"side frames are adjustably mounted upon the respective shafts for the purpose which-will presently appear.

The shafts'25, 25' are also provided with series of spaced wheels or collars indicated at 29 and 33 for supporting two pairs of relatively adjustable male and female creasing members, which are preferably in the form of suitably shaped rigid bars.' One pair of said creasing 31 and 32, is carried by suitable brackets secured'to and supported by the wheels or pulleys 29 and 33. The creasing members of the other pair, are secured at their opposite ends to suitable flanges or pulleys 36, which are rigidly attached to the inner intermeshing gears 37 37' and 38, 38. which are so mounted upon the shafts 25, 25" that they may be freedpr loosened thereon to permit their supporting shafts to independently rotate in said gears when the gears and their attached creasing .members are held against motion. Upon the bar 201 extending across the machine and supported in brackets upon the side frames 3 and 4 are mounted adjustable-gear looking members 200, one of which is shown in detail in Figs. 14, 15 of the drawings. Each of these locking members is adjustably keyed upon its supporting bar and provided with two inwardly presented gear-engaging teeth 202. These locking members 200 can be moved longitudinally upon their supporting bar so as to intermesh with the teeth of gears 37 37 to hold said gears and the gears 38, 38 against increment when the gears and connected creasing members are loosened upon their shafts. With the intermeshing gears so shafts carrying the fixed pair of creasing 3 11"- are rotated in the desired direction to change the circumferential distance between the fixed and adjustable pairs of'creasing members ti suit the desired size of box blanks that are to be made. When the desired ad ustment has been effected, the inner set of intermeshing gears 37, 37 and 38, 38', with their =ttaclied creasing members are again securely fastened te their respective shafts and the locking-members 200 moved out of engagement with the gears 37 37,

when said properly adjusted pairs of creasing members will be ready to cofiiperate in members, indicated at indicated at 34 and I the said frames constantly locked against motion, the.

the production. of box blanks of the desired size. Suitable provision is made for fastening locking members 200 upon bar 201 in eitherof their engaged or disengaged posi-. tions.

Continuing onward the board, which is in the process of passes between two vertically spaced horizontally positioned shafts 40 and 4O journaled atv their opposite ends through bearings 41, carried by the respective frames 3 and 4 of the machine, said shafts each carrying'at their adjacent ends interlocking gears 42, which latter mesh in turn. with gears 43 and 44 rotatably journaled on pins 44' on side frame 3 and respectively above and-below said first-mentioned gears. These shafts have secured thereto pairs of longitudinally adjustable rotary trimming knives 45 and 46 for cutting to the desired length the board as it passes therebetween, said shafts also -bein provided with spaced pairs of feed rolls 4 for insuring a continued and uninterrupted passage of the 'said blanks.

Still further as the blank continues through the machine, it passes between a pair of vertically spaced, parallel, horizontally extending shafts 50 and 50 through bearings51 in the respective frames 3 and 4 of the machine and carrying upon their outermost end portions and outside of interlocking gears 52-52 and 53-53 respectively, while between the said frames the said shafts carry spaced pairs of collars 54, secured thereto and in turn carrying flat bars 55, provided upon their latterly opposite sides with radially inwardly converging surfaces to provide a dove-tail'cross-section (as shown in Figs. 8 and 10). Further. surrounding the said shafts 50 and 50 are spaced pairs of collars 56, to which are secured flat bars 57, of dove-tail cross-section like the bars 55 above described, the opposite end portions of said bars 57 being secured indirectly to constantly interlocking pinions 58-58 and 59-59, respectively, mounted upon shafts 50, 50 inside the side frames 3 and 4. These gears 59, 59 upon shaft 50' are geared respectively to the gears 38, 38' upon shaft 25 termediate pinions 220 journaled upon stud shaftson inner sides of frames 3 and 4. By this gearing the inner sets of gears 37, 37', 38, and 53, 58', 59, 59" will always act in unison and be held against motion when locked by member 200.

The two bars 55 carry inter-engaging dies 60 and 61 as hereinafter described, while the. said bars 57 also carry spaced pairs of coiiperating dies 62 and 63, which latter can be shifted circumferentially about their respective shafts by temporarily loosening the formation into a box blank,-

by means of injournaled respective collars to said shafts. in fixed position, thus by saidadjustment adapting the machine to form blanks for various sizes of boxes. For the purpose of forming blanks such as that shown in Figs 39, a set of dies 64 and 65 (Fig. 4) are secured to the bars 57 at the end-portions adjacent to the frame 3 and of a construction hereinafter described. From between the last-named pair of shafts the blank passes onward between a pair of rolls 67, which operate to remove said blank from the (lies between which it has just passed, and to deliver it to a platform or the like as may be desired.

For driving the various elements of this machine there is provided a counter shaft 70, preferably carrying a belt pulley 71 and a pinion 72, said shaft being journaled through spaced bearings orbrackets 73, de

pending from the underside of the bed plate 1. The pinion 72 meshes with a gear 74, secured to the shaft 50 which by means of the interlocking gears 52.-52' and 53-53 rotates shaft 5O. The gear 52 meshes with the pinion 43 which by means of the cooperating pinion 42 also drives pinion 44 which latter meshes directly with the gear 28, cooperating with gear 27. Also meshing with gear 28, is the pinion 21 which turn the pinion 20 of the shaft 16 while meshing with the gear 27' is the pinion 18 which also cooperates with the pinion 17, of the shaft 16. The rolls 67 are driven by idler pinions 67 intermeshing with ears 52 and 53.

Re erring to Figs. 20 and 21, an auto- .matically adjustable feed roll segment is shown in detail, the position of the same within the machine being shown clearly in Fig. 2 immediately adjacent to the upper and lowermost creasing members carried by the shafts 25 and 25. This'roll segment esber in operation to provide for the useof various thicknesses of paper, cardboard, corrugated board, or the like, in the manufacture of. box blanks.

In Figs. 22, 23 and 24 is shown in detail another form of segmental feed roll comprising abody portion 118 provided with a radially extending flange 119 from whichprojects laterally an integral shoulder 120 in turn provided with a radially outer face 121 formed upon an are about the center of theshaft upon which said roll is mounted,

-member of a set of cooperating segmental pairs thereof for insuring a positive feed of the box material through the machine and it is to be noted that while one of the members of each pair is mounted upon each of the shafts 25, 50 and constructed as shown, the other is mounted upon each of the shafts 25, 50 and is substantially the same except for the fact that its feed surface is an integral part of its body and is not adapted to yield from its normal position as material of various thicknesses comes into contact therewith. The members shown comprise a semi-circular yoke portion 125, having apertured reduced end portions 126 fitting between'and pinned to the lugs 127 of the bifurcated ends of a second semi-circular yoke member 128. Extending radially from the central portion of the member 125 and integral therewith is an arm 129 provided with an enlarged head portion 130, adjacent to which is positioned in parallel relation therewith a segmental feed plate 131. Said plate is provided with inwardly extending pins 132 adapted to pass'slidably through relatively larger radially extending apertures 133 in the head 130, said pins being prevented from more than predetermined movement by pins 134 extending transversely through the inner end portions thereof. The head portion 130 is also provided with enlarged recesses 135 extending.,inwardly from its outer surface and adapted to form cups for the retention of coil-springs 136, which at their outer free ends press against the inner surface of the feed plate 131 and tend to maintain the same yielding in its outermost position. These segmental-feed members are used only when working upon sheets which are too narrow to reach from the shafts 16, 16 to I the shafts 40, 40.

The rotary punches and dies carried by the shafts 50 and 50 are shown in detail in Figs. 8 to 11, inclusive. As hereinbefore described, said shafts are encircled by collars 56 having secured thereto longitudinally extending dove-tailed bars 57, while adjustably' mounted upon the latter are the supporting members for the punches and dies on the shaft 50, each of the punch supporting members 140 has a beveled sur-' face 141 adapted to cooperate with one edge portion of said bar and is provided also with an adjustable member 142 having a beveled surface 143 adapted to adjustably grip the, edge portion of said bar. The

outermost surface of the member 140 is pro- 158 formed with of similarly extending apertures 155, in portion 151. Die

inclusive.

vide d with a radially inwardly extending longitudinal recess 144, in which is adjustably positioned a ground segmental punch member 145 by means of set screws 146.

Positioned upon the shaft 50 and exactly in alinement with the punch and mounting 'ust described, is a corresponding die and its mounting. Specifically, this. latter comprises a segmental die supporting member suitable integral strengthening ribs on one lateral face and a curvedshouldered recess in its other lateral face to receive a circumferentially adjustable member 150 having a transversely extending portion 151 recessed upon its outer surface'152 and adapted to receive a ground die plate 153, having a longitudinally extending aperture 154, the sides of which taper radially outwardly and lie substantially in planes with the corresponding sets plate 153 is secured in recessed face 152 by suitable means, not illustrated. Plate 153 is omitted from Fig. 8. The box blank shown in Fig. 39 illustrates the shape of slits cut by punches 145 and dies 153, while the shape of a box blank formed by the sole use of such dies as that shown in Fig.37 is shown in detail in Fig.

40. Each of the members 150 is adjustably secured bymeans of a bolt 156', passing slidably through elongated apertures 157 to a member 158, which in turn is provided with.

a diagonally disposed surface 159, adapted to cooperate with one side of the dovetailed bar 57 carried by the collar 56, while the opposite sideof said bar is held by a member 160, secured by a bolt to the memher 158.

For forming the cut-out portions 170 shown at one end ofFig. 39 and adapted thereby to create a tapered tongue 171, flap dies and punches are provided such as are shown in plan detail in Figs. 16 to 19, The punch two cut-out portions as the box material passes through the machine, while the punch and die pair of Fig. 19 forms the second of said portions. in construction and operation and the punch of each comprises a shearing bar 175, having a cutting edge 176, while said bar is curved outwardly at 177 and provided with the flap cutting edge 179, said bar also beremovably secured within angularly related slots 178 within the radially outer surface of a base member 180 secured by bolts 181 to a member 182 in turn removably and 'adjustably secured to the dove-tailed bars 57, carried indirectly by the shafts 50 and 50.

The corresponding .die for the shearing and cutting' punch just described comprises as the respective the arrows the the I the ,the box blanks,

terial forced thereinto by and die pair shown in Fig. 18 is adapted to form the first of the The said pairs are similar the paper 179 of the said punch cotiperates in alinesaidtbar terminating adjacent to an ane cutting edge ment with the similar arc 186,.corresponding with the curved portion 187 of the punch shearing edge 186. With dies and punches come together in rolling contact in the direction-of circumferential cutting of the box blank is efiected by means ofnla shearing cut while the conver ing sides of the tongue portion of the said lank are cut similarly by pressure of a cuttin edge against a relatively smooth surface. he operation of the oppositely disposed pair of flap cutting dies and punches 1s shown in a 19 wherein the same similar manner by Fig. numerals are used as in Fig. 18 except that each is primed.

this construction In forming the transverse creases 190 in I 7 male and female creasing members are used such as for instance those shown in detail in Figs. 30 to 36, inclusive. Therein a male creasing member 192 (or 192 or 192 or 192") is rigidly yet re 193 and movably held by adjustable means 193 in a suitable mounting 194 secured in turn in any suitable manner upon the shafts 25 and 25. and one of the pairs being. immediately to the rear of the feed members shown in Figs. 20 and 21. Corresponding and co'ciperating with the said male creasing members are positioned female creasing members 195 (or 195' provided with longitudinally extendin slots 195 of various widths as shown in igs. 35 and 36, the latter being a bar having slotsof four distinct widths 195 which upon having-the box mathe working portiOns 196 of said male members, such as those" shown-in Figs. 34 and 35, forms the creases 190, upon which lines the blank may be folded to ultimately form a box.

The longitudinal creases in the blank are preferably rolled in by means of rolls 197 secured by means of collars 198 to the shafts 16 hnd 16 (Fig. 7) and adjacent to the feed rolls 15 hereinbefore described in detail. The radially outer surfaces 199 of said creasing rolls are corrugated and coiiperate in such manner that the ridges of each force into the grooves of the other of each pair, this form of crease having been found to bemuch better than those wherein a'single male member rolls the paper into a female member.

When it is desired to set the ma-hne t a cut out blanks of a definite epze. the lo -king members 200 are shifted upon their shaf': 201 to engage the teeth of gears 31'. 37" tfirmly hold them against rotation upon the shaft 25. Smce these gears are ;n intermeshing trains with the gears 38v 38", .38, 58'

' and 59, 59, as hereinbefore described, this entire system of gears upon shafts 25, and 50,50 will be held against motion. The enumerated gears and the creasing bars, punches and dies, which are connected to them as hereinbefore described, are then freed upon their shafts by loosening up the set screws that normally secure them in position. The intermeshing system of gears 27, 27, 28, 28, 52, 52' and 53, 53 fastened to the shafts 25, 25 and 50, 50 outside of the side frames of the machine, as well as the other pairs of creasing bars, punches and dies that are fast upon said shafts, are then rotated, by hand or by power, forwardly or backwardly, to circumferentially adjust the distances between the several pairs of creasing bars, punches and dies. It will be understood that those members that are fast upon the shafts will move with the shafts while the members that were loosened or disengaged from the shafts will be held against motion during this adjustment. When the desired adjusted relationship is obtained, the inner system of intermeshing gears together with the creasing bars, punches and dies connected with them are again made fast upon their shafts and the locking members 200 shifted out of engagement with controlling gears, when the machine will be in readiness for operation. The longitudinal positionsof the punches and dies, as well as the shearing wheels and 46, may be adjusted upon their respective shafts by loosening the bolts which fixed "position.

Having thus described my invention, what I claim and desire to protect by Letters Patent of the United States is hold them in normally 1. In a machine of the character de-,
