@LETTING MAC l=1 I To all 'whom t may concern.

Be it knownthat JAMES A. CON, a citizen of the United States, and a resident of New York city, in the borough of Brooklvn, count, of Kings, and State of New ork, and anni' MCC. donns'ronn, a citizen of the United lStates, and a resident of Roselle Park, in the county of Union and State of New Jersey, have invented'certain new and useful Improvements in Slitting Machines, of which the following is a speciication. y

This invention relates generally to slitting machines for exible materials and has for its main object and feature the provision ci means whereby' two groups ot' slitting elements may be employed in connection with complementary slitting' means together wlth devices whereby one group or' slitting elements may be adjusted to produce a diHerent width of section while the other group 1s cooperating with the complementary slitting` means to the end that the slitting operation may be changed from one width to another without breaking the 'flowing web and with out. stoppingA its iiow. 'lhe broad features or" the invention herein disclosed are claimed in application Ser. No. 678,332 liled December 53, 1923. The slittino; means emplpyed may of course vary widely and may be elther ot the score-Cut or 'the shear-cut type, and, il ot the sheancut type, the arrangement may be as disclosed in application Ser. No. 678,- 334: tiled llecember 3, 1923, and some ci the claims herein are intended to cover the disclosure of said application Ser. No. 678,334 tiled December 3, 1923, and also to cover some ot the features disclosed in application Ser. No. 678,332 led TDecember 3, i923.

ln the accompani/inf.;r drawings the inven` tion is disclosed in a concrete and preferred term in which l is end elevation of a machine embodying the invention.

Fig. l is a 'tt-ragnientary view oit a latch that may be employed in connection with the invention.

lullig'. is a sideelcvation ot the machine shown in lligfn i.

lig. 3 is 'e transverse vertical sectional view on the plane oit line 3 3 of Fig. 2.

lfig. Ll is a longitudinal vertical sectional view on the plane ot line of Fig. l..

Fig. is a diagrammatic view of a slitting operated in unison by reason et two machine associated with a board or paper making machine and a sheeter. v

The slitting devices include two sets, one

consisting here of slitting means 1 which isk `devices consists of member l and the group' of score-cutters 3. 'lihe two or more groups 'of score- cutters 2 and 3 are mounted on the carrying member l which latter is mounted to turn in a suitable support that will hereafter be more particularly described, and are spaced apart circumferentially on the carrying member, beine; mounted on faces 5 and '6 of the carrying member. llt will be understood that, it one group ot score-cutters is .in engagement or proper position with reference to member l, the other group may be adjusted by slidingi them along; the face of the carrying member after which they may be secured in position by means ot screws 7, lf it is now ydesired to vary the width of the slitting sections, the carrying member is turned in its bearings to bring said other ,sgroup ol cutters into properl position with respect to member l and this can be done without breaking; web 8 or interruptinnr its How. lin addition to the adjustments described, it is preferred to mount the carrying member in a snpportthat can be moved toward and away from member l; and it is also preferred to have means to slide the carrying member longitudinally of its anis.

As here disclosed these parte taire the fol?.

lowing forni z 9 indicates a framework in which is mounted a support here consisting1 ot'two' arms l() and ll. These arme are pivotally supported on center l2. rlhe free ends ottV the arms are provided with bearings l and il and in these bearings the carrynng member l is mounted., Any suitable means may be provided to roch the but, prefere ably, each arm carries a sector or io with which engage screws ll' and lp'. that can be i pairs oit bevel gears lo und handle 2U., (Jarry/ing member l is provided with a sleeve 2i that carries e gear 22'and with this geen meshes pinion 23, the center of which is at 12. Handwheel/,2i is connected to pinion 23 so that by turning said handwheel, the carrying member may be turned in the bearings of the armste bring either group of cutters into engagement with member 1. Mounted on one of the arms is a latch 25 that consists of a bolt 25a 'spring pressed into one of a number of apertures 26 of the carrying member or extension thereof so that, when the carrying member has been turned toa proper position, it becomes latched in position. To withdrawthebolt, handle 27 is .turned andn cam face 28 moves bolt upwardl and out of aperture 26'. At times, it is diasirable to be. able to move the carrying member lengthwise to compensate for an uneven feedof material from the board mill or paper making machine. c In order to be able to do this, extension or sleeve 21 is 1n slidable engagemet with the carrying member by means of key 29 and carries a threaded stem 30 that engages corresponding threads in the carrying member. By turning handle 31, :tast to stem 30, the carrying member is moved lengthwise of'its own axis in the bearings of thel arms.

In operation the preferred practice is to lower the arms away :trom member 1 and then to turn the carrying member in its bearings.4 l

In Fig. 5, the slitting machine, designated generally by 32 is shown between board mill or paper making machine 33 and sheeter 34. The web is led from the paper making machine over guide roll 35 and through the slitters and thence'to rollers 36 ofthe sheeter which latter rollers act to pull the web through the slitting machine.

The broad idea, disclosed herein, of score cut slitting means to sever aweb into inde4 pendent longitudinal sections without distorting the sections out of parallelism together with a feeding device to exert anV equal pull on all the sections to thereby advance them in arallelism and severing devices lto cut t e sections substantially-at right angles to their longitudinal advance is not claimed in the present application but forms the subject matter of another appli-4 cation filed Nov. 21, 1924, Ser.- No. 751,410.
