CREASING AND SLITTING MECHANISM.

Application filed December 20, 1915. Serial No. 67,816.

To all whom t may concern.'

Be it known that l, CHARLES R. SEYMOUR,

a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented'certain new and useful Improvements in Creasing and .Slitting Mechanism, vof which the following is a specification.'

The present invention has for its object to provide improved mechanism for operating upon a web of material, such as lined corrugated board, paper board for making box blanks, or other similar materials. rlhe operations performed upon the web of material may be the formation of creases in the web, or slitting the web'longitudinally,

.or both, the specific character of the operations performed upon theweb'being dependent'upon the character or type of the elements associated with the mechanism for performing these operations.

The mechanism herein disclosed was designed especially for operating upona web of lined corrugated board, but as will hereinafter appear, other materials than lined corrugatedv board may be operated upon just as efficiently. In the present instance, the mechanism is provided with cutting and crea-sing elements for providing the web with a plurality of longitudinal creases and for slitting the.web longitudinally. The cutting and creasing elements are rotary andare mounted upon two pairs of rotary mandiels or shafts, which, in turn, are arrangedin a vertical series. Mechanism is provided for raising and lowermg the entire series of shafts to bring either pair into operative relation with the web of material so that the latter will pass between the shafts of such pair, and rhence between the cop- `eiating cutting and 'creasing elements on these shafts. `While one pair of shaftsand the cutting and creasing elements thereon are being utilized for operating upon the web of material, the other pair of shafts are in their inoperative position. While two ofthe shafts with the cutting and creasing elements thereon arein their operative'position and operating upon the web of material, the cutting and creasing elements on the two shafts in the inoperative posit-ion may then be adjusted for the succeeding 0rder, that is for the manufacture of a slitted and creased web having the creases and Specification of Letters Patent.

probably the slits formedin the web along other lines. l

As above stated, the present mechanism i was designed for operating upon lined corrugated board and was designed especiallyY for use in combination with the machine disclosed in the co-pendin-g joint application of O. M. Hoch and m-yself, Serial No. 69,097, filed December 28, 1915. The mechanism forming the sub-ject matter of the present application is disclosed in the abovementioned 'co-pending application combination with mechanism for performing certain other operations upon the web, but is not claimed therein. It will be understood that the cutting and creasing mechanism herein disclosed isnot limited'l to use in com-` bination with a machine of the above-men;

tioned`character, but maybe used as -a unit by itself or in combination with any other mechanism necessary for performing other operations upon the web.

The invention is illustrated in the accompanying drawings, in which:-

Figure l isa vertical longitudinal sect-ion through the center of the improved slitting or cuttmg and creasing mechanism; and

Fig. 2 is a rear elevation, partly in section, of the improved cutting and creasing mech` anism. y

Referring to the drawings, it will be noted that two pairs of shafts or mandrels are employed, the shafts of one `pair being ,shownat l and 1, respectively; and those of the other pair at 2 and 2, respectively. Each pair of the shafts has positioned thereon, the elements for performing` the necessary operations upon the web. In the pres,- ent instance, creasing blades and slitting knives arc mounted upon the shafts, the creasing blades `for the shafts 1 and l bein'g shown at 3, and the-slitting knives for ,the/shafts l vand l being shown at 4. Likewise, the creasing blades for the shafts 2 and 2 are shown at 5, and the slitting knives for. the shafts 2 and 2 are shown at G. rlhe number of pairs of slitting knives and creasing blades will depend upon the number of places at which the web is to be slitted and the numberv of creases with which the web is to be provided. In the present instance, the pairs of slitting knives atthe extreme ends of theshafts are for the purpose of trimming the edge portions of the webfand the pai'rof knives shown at the mid-portion of each pair of shafts is for the purpose of dividingv the web longitudinally.- The creasing blades are provided in suficientv number, in the present instance, to provide th'e'web with two creases at either side of the central slit. It is obvious that the exact arjV rangement of these elements upon the shafts is immaterial and the number thereof may be decreased or increased, as desired. Furtherymore, it is not even essential that the elements take the form of cutting and creasing blades, because so far as the broad aspect'of invention are concerned, it is immaterial what the specific character of the elements upon the shafts happen tobe. v

Both pairs of shafts are mounted housings 7 and 8, which housings are mount'- ed for vertical' sliding movements in .Yth'eside frames 9 and 10', respectively. The side` f rames 9' and' 10 may be supported in"" a nyj suitable manner, such as upon the fra'iiienllvl of the machine in combination withwhie'h the present. cutting and creasing mechanism is used. Each side frame is providedlwith the guideway 12 in which the corresponding housing is adapted to slide. Thespeciic manner o f slidably mounting the housings in the guides 12 is immaterial, but, inA

the present instance, eachof the housings-` is provided with gibs 13 and 14, capable ofre-l taining the housings in -place withrespcct vto the frames 9 and 10 and the guideways 1 It is obvious that by turning the shaft 17,

the pinioiis 16 will rotate and either raise or lower the housings 7 and 8 in the frames 9 and .10. This is for-the purpose of bringing one or the other of the pairs of :Shafts into proper relation with the web of material, so that thesame will pass' between the shafts so brought into operative position. In order to facilitate movement of the housings from the shaft17, links 19 may be ,pivoted to the lower portions vo f the houspass between 'the shafts of the upper pair and hence, be operated upon by the cutting and creasingcelements Aassociated with said shafts.' The Y'webmay be'fedto the shafts by. hand, if desired, orwhen the present cutting and creasing mechanism is associated 'with a machine for performing other operati'oifi's upon the web, the feedingelements of such machine may be depended upon to feed the web to the cuttingandv creasing shafts. Fig. 1 shows-a discharge belt 21 `for conducting away theweb. Thisdischarge beltand the mechanism associated therewith constitutes a portion of the machinedisclosed in the above mentioned co-pendingapplication. When either set or pair fof 'shafts is brought into operative position it is desirable to lock the housings 7 and 8 yin position. This may be done by' providing a lockiiig pin 22 at each side of the machine mounted in'the corresponding side frame.v These pins are mount-ed to slide longitudiupper pair of shafts is in the operative position, the extremities of the pins 22'are capable of engaging in openings 24 formed in `the housings 7 and 8 to support or lock the housings 7 and 8 in place, and when the flower pair of shafts is in operative position, the extremities of said pins are adaptwise lock the housings in position. It is `obvious that before-tlie housings canbe moved to change the position of the shafts, the pins 22 must be withdrawn against the tension of the coil springs 23.

Means., is preferably provided foradjusting the distance between the two shafts of each pair to either mo've the cutting and nally and are held in their innermost positionby means of coil springs 23. When the'` y ed to engage in similar openings-25' to likecreasing blades toward or away'from each other. This may ber done by mounting the lowermost shaft 1 of the upper pair and the uppermost shaft 2 of the lower pair in bushings 26, which, in turn, arev rigidly mounted in the housings 7 and 8. r'The upper shaft l of the upper pair and the lower shaft 2 of the lower pair aremounted in 'I bearing boxes 27, which are capable of sliding vertically in the housings 7 and 8. The two upper boxes 27 have associated therewith upwardly projecting hub portions 28 which are internally threaded to lreceive a screw shaft 29. Each screw shaft 29 is rotated by means of a beveled gear 30 mounted thereon which meshes with a beveledpinion 31. The two beveled pinions 31 (Fig. 2) are mounted upon a transverse ,shaft 32 supportedl by means of brackets 33 on the housings 7 a'nd 8. The extremity of theshaft 32 ismsquared as shown at 34; to receive a crank handle by means of which the shaft 32 may be rotated' to simultaneously raise or lower the two upper bearing boxes 27. vIt is obvious that the raising or lowering of 1. 'Lerares the two upper bearing boxes 27 adjusts the distance between the shafts'l and -1 of the upper pair.

A similar arrangement comprising screw shafts 29 engaging with the downwardlyextending hub portions 28 of the' lower Abearing boxes 27 serves to adjust the disceiving a crank handle to rotate the shaft.

By rotating the shaft 32', it is obvious that the lower boxes 27 will be raised or lowered to adjust the distance between the shafts 2 and 2 of t-he lower pair.

The shafts which carry the creasing lelements are positively rotated by mechanism designed so as not to interfere with t-he vertical movement of the shafts and-which is designed to positively drive the two shafts which happen to be in operative position. As shown in Fig. 2, a driving gear 35 is provided'which may be driven in any appropriate mannerdepe'nding upon the relation in which the present cutting and creasing mechanism is used. rlhe gem- 35 is mounted upon a stub shaft 36 which also .carries a pinion 37, so'that the gear 35 and the pinion 37 rotate in unison. The lowermost shaft of each pair, that is the shafts l and 2', have secured thereto gears 3S and 39, respectively. The pinion 37 and gear 35 are so positioned with respect to these gears 33l and 39 that when the upper pair ofishafts.

is in the operative position, the pinion 37 wlill`mesh with the gear 38, and when the lowerpair of shafts is in operative position, the pinion 37 will mesh with the gear 39. `When the gear 38 is rotated, the shaftl is positively rotated and transmits motion to the shaft 1 through the meshing gears 40. Likewise when the gear 39 is rotated, the shaft 2 imparts motion to the shaft 2 by means of the meshing gears 4l. It is, therefore, obvious that the two shafts of whichever pair happen to be in operative position will be positively rotated from the pinion 37 and the gear 35.

lVhile one pair of shaftsand the cutting and creasing elements thereon are being utilized to operate upon the web, the cutting and creasing elements upon the other pair of shafts may be adjusted and re-positioned for the next ob or order. 'In order to facilirtate the positioning of the elements upon the shafts, a gage or scale 42 is provided (Fig.

l) which runs longitudinally o`f the shaftsy and is supported on brackets 4:3. Each-of the brackets 43 is mounted tov slide on and pivot about the rod 44 carried by the housings 7 and S. The brackets 43 are normally cutting and L42 adjacent to the cutting and creasing elements on veither of the intermediate shafts. When 'the scale is thus brought into close' relation with the cutting and creasing ele- `ments on either of the intermediate shafts, said elements may be properly spaced. The corresponding cutting and creasing elements on the coperating shaft may then be spaced accordingly. 4

rIhe above-described double or duplex arrangement of the parts for operating on the web of material -with means for bringing either set of the parts into operative relation may be applied to other machines than machines of the specific type herein disclosed. So far as this @feature is concerned, it is immaterial whetherthe operating `elements upon the shafts are cutting and creasing blades or lotherelements. Furthermore, various changes may be made in the details of constructionas above described without departing from the spiritor scope of the invention, as defined in the accompanying claims. y 4
