Te. all it may concern:

Be it knownthat we, JAMES A. CAMERON and Gus'rsr B. BIRCH, citizens of the'United T 3 States, and residents of the borough of State of New York, have invented certain new and useful Improvements in Shtting and Rewinding Machines, of whichthe fol:

This invention. relates to slitting and re- 1 Winding machines generally and in particular to slitting and rewinding machines. of the surface rewind type.

' In the art of slitting and rewinding sheet material as heretofore practiced, machines o'f the'surface rewind type, of which that shown in Patent No. 1,076,189 is anexam- 'ple, have been constructed to operate sucencedin adapting these machines to handle- 'ce'ssfully on rollsof material of 'mediurn size. Difiiculty, however, has been experithe massive mill rolls that are being produced in constantly 'increasingsizes as the art of manufacturing such material'is de veloped. These difliculties have taken various forms. One of them, has been tl18 l1n possibility, with the t pe" of top pressure roll mechanism-hereto ore used, of mounting the rewinding apparatus on a low frame [to thereby .secure stability of the rewound coil supporting means and facilitate the removal of the finished coils.

Another clifiiculty" *connected with the use of large and cumbcrsom'e'mill rolls has been the question of longitudinally adjusting the mill roll in its support to properly align the web with the cutting mechanism; It'has also been found that with certain materials, it has sometimes been diflicult to rotate the cutting discs at a winding function and serves sufiiciently high speed to insure a perfect slitting of the Web.

The-large size of the deflecting roll not only adds to its rigidity, but, in addition, a large area of contact on the roll is applied to the surface of the Web so that the speed of travel of the web and, to a great The main object of this invention is to' in. 1,465,964, dated August 28,1923. -Application for reissue filed July 17', 1925."

In one form of the invention the large deflecting roll serves also as a rewound coil supporting and rewinding roll, but in another embodiment of the invention, this roll is so mounted as not to perform a supporting or reand draw the web through the machine. In either of these forms of the invention the cutter roll is preferably driven at a higher peripheral speed than that of the large deflecting roll and, consequently, than the speed of travel of the web. The invention solely to guide consists also in the provision of means-fol controlling the rotation and the longitudinal placement of the mill roll shaft. Other features of the invention will be'referred to as the description proceeds.

In the accompanying drawings there is illustrated a preferred embodiment of the invention, but it is to be understoodthat the invention may be carried out byother embodiments and by mechanism widely different from that selected for illustration.

slitting mechanism having this general in.

rangement is'alsoshown in Figure 13 of the drawing in this case. In the embodiment'of the slitting mechanism which is best shown in Fi 2 of. the drawing the rear-rewindin ro '1', and not the relativegg larger front rewinding roll 2, is employ as a cutter roll. Co-operating with the cutter r0111 are the cuttin discs 7 which slit the web 88 as it passes in the mill roll 8 overfthe guide roller and tensioning device 10 it: its we to e'rewindmg' m the cut of the invention in- Figure 15 thefront rewinding roll 2, which inthiscaseis ualinsiretotherearrewind roll 1, isemplo ed as the cutter roll an a special'web d ecting, or-breast,.

. roll 191, which is relatively larger than rewinding rolls 1 and 2, is mounted out-of contacting relation with the ,rewound coils. The cutting 7 as shown in Figures" 2, 13 and 14, are preferably journaled in bars the" 11 which are in turn moimted in channels 12 in the members 13 and adapted to rock therein about the fulcrums 14. The spacing members are adapted to be moved along the head of the sup rting member 15 and to be rigidly clam in any desired position thereon by means ofthe thumb screws 16. The base of the support' 'momber 15 is slidahly supported in brac ate 1'! firmly clamped to the stay rod 18 which ex tends acros' the machine. An ecwntric shaft 19 also extends across the machine and is provided with reduced bearing portions 17' which are journaled in the brackets 17 and in the framework at the sides of the machine. The member 15 bears through the wear ieces 20 the eccentric shaft 1% w ereby when the shaft is rotated the meinbef 15will raised or lowered to move the cutting discs 7 intoor .out'of engagementwith the cutter roll 1.- In order to manipulate theeccentric' shaft 19 a spiral gear 21 is provided on the end of the shaft which meshes with a spiral gear 22 mounted on a rod 23 whichterminates inthe hand wheel 24- at the front of the machine as shown in Figure 1 of the drawing. A. locking screw 87 serves to hold the parts in set position. I

The cutting discs 7 are preferably resiliently pressed against the cutter roll through the action-of the leaf springs 25 which are mounted in the cutting disc supporting bars 11 andbear at'their extended extremities against the abutment beam .26. The beam 26 is preferably .80 mounted that it-can be withdrawn bodily out of'engagement with the .ends' of the springs 25. For this purpose the top of the beam 26 is adapted-to slide along the lower surface of the lugs 27 projecting from the brackets28. A rack 29 carried by the beam 26 meshes witha pin-. ion '30 and provides a means for'moving the beam. A guiding lug 31 carried by the beam co-operates with the roller 32 to hold the beam in sliding engagement with'the under surface of the lug 27. -The pinion 30 is mounted on a stub'shaft 33 which carries at its outer end a hand lever 34 as shown in Figure lby means ofwhich the shaft 33 and pinion 30 can be rotated and the beam 26 thereby moved to free .the ends offthe springs 25, whereupon the cutter disc bars 11 can be lifted out of the spacing members 13. Apawl 35 co-operates with a ratchet 36 on the stub shaft 33 to lock the shaft 33 and pinion 30 and thereby hold the beam 26 in spring engaging position.

In the form of machine shown'in the patent referred to, the rewinding roller which is used to apply pressure to the upper surface of the rewound'coils is mounted in a framework'which is provided with down- Wardly extending guide members which are supporting framework.-

inou'nting gives very satlsfac'tory results with adapted to move vertically with the roller This form of a machine having a high framework such as is shown in the patent, in which ample space is provided for the downward extension of the guide members. In the present I invention, however, one of the objects is to provide a machine having a low frame and 'to accordingly devise a form of mounting in which downwardly extending guide memlbers are not used; To this end thetop pressure roller 5 is preferably- 'journaled at the ends in the carriages 37 whichare rigidly connected by. means of the beamfi'l which I 1 extends from side to 'side of'the machine for this purpose as shown in Figures-.2, 4 and 5. In lieu of the downwardly extending guide members of the patent the carriagesin this instance are provided with guide rollers 38 which engage and travel along the stationary vertical guide posts 39 as the'pressure roller 5 is lifted in accord ance with the increasing diameter of the rewound coils. 4 I

The posts 39 form a rigid part of the framework of the machine-and serve to support the headpieces 40 to which tie rods extending. across the top'of the framework may bejattached. Additional guide posts -41-extend through the framework of the carriages. 37 and vserve as sliding ways for the U-shaped guide members 42 which direct the vertical movement of the rewind shaft 4 as the rewound coils 3 increase in diameter. Horizontal movement'of the rewind shaft lugs 43 carried by the guide members 42 and between which the reduced ends 4 of the shaft & are held. The guide members 42 are preferably made in sections which are clamped' together as shown in Figure 10,

and are preferably adapted to be'locked in an elevated position by means of the thumb I screws 194.

' It'has been found in practice-that the rew'oundcoils can be most effectively built up if the rewinding roll 1 and the pressure roller 5 are rotated at a higher peripheral speed than the peripheralspeed of the re- .winding and supporting roll 2. It has also been found that the slitting operation ris is prevented by the downwardly extending facilitated by providing for the rotation of 'the slitting discs at a peripheral speed at least equal tothe speed of travel of the web. Inorder to insure the rotation of the slit-' ting discs 7' at the required speed they are preferably arranged to co-operat with the rewinding roll '1. as shown in Figure 2,

which, as has been stated, rotates at a higher peripheral speed than the peripheral speed of the rewind roll 2 which determines the speed of travel of the Web." The engagement of the discs 7 with the cutter roll 1 serves to rotate the discs at a peripheral speed .at-

least equal to, and preferably slightly higher than, the speed of travel of the web 88 and results in a more effective operation of the slitting discs 7, since they are thereby caused to'sevcr the material with a sliding out instead of merely pressing their way-through it. The effectiveness of the slitting operation is stillfurther increased, by mounting the discs 7 notdirectly'at the point of tangency of the stretch of the web .with the cutter roll 1, but offset somewhat from-this point toward the direction from which the web is; movingv so that the web is, put under 1 a certain amount of tension by the direct engagement therewith of the slitting discs as it passesover the discs on its way to' the cutterrolll. a v

It will be seen that the pressure exerted by the slitting discs against the web will pleted when the web points of engagement the disc 7 and the cutter roll 1.

rolls from a condition of rest. noted that both of the rewinding rolls 1 have a tendency to initiate a cuttin operation which can then more easily com asses between the 7 It will bee noted that, in the aim of the invention shown in Figure 2, the front rewinding roll 2 has agreater'diameter than has the' rear rewinding end cutter roll 1.

The purpose of this is to secure'a suflicien't degree of rigidity of this roll so that it will withstand the enormous strain put upon it in unwinding the web from the larger mill rolls and particularly in artin the mill t will be "and 2 and also the riding roller 5' all play a part in the rewinding and consequently rect contact'with the web. It will be seen.

that b means of this. large area of contact the r0 1 2 is enabled to exert sufiicient friction on 'the'web to insure that it will be uniformly and positively fed'through the machine at a speed equal to the peripheral speed of the roll.

In the arrangement'of the cutting and rewinding mechanism shown in Figure 15, the L rear-rewindingroll 1. and the front rewindin roll 2 are preferably of the same Size an the front rewinding roll is utilized as 'acutter roll. In order to utilizethe front roll as a cutter roll and at the same time to rotate the cutter roll and the cutting discs 9 at a relativel greater speed than the speed of travel of t e web, in this modification an enlarged driven breast roll 191 out of engagement with the rewound coils but adjacent the front roll 2 is made" use of. .The function of the large breast roll 191 is substantially the same as that of the large rewinding roll 2 of Figure 2, that is, to guide and draw the web through the machine. In

this arrangement, however, the large, roll is relieved ofthe rewound coil supporting function which is characteristic ofthe large roll 2 of Figure 2. In this arrangement'as in the arrangement 'of Figure 2, the speed 'of travel of the web is determined by the V sivel speed of travel of the large roll. In Figure 15, however, the speed of peripheral travel offour, instead ofthree rolls, isprogresincreased. That is,- the peripheral of the breast roll 191, whlch is the speed of travel of the web, is at a certain ratethe peripheral speed. of the front rewinding 2, which governs the speed of the ripheral speed of the. rear rew ding ,-coil 1 1s still greater; and the peripheral speed of cutter discs 7, is slightly gr ater; the pe i the riding roller 5 is greatest of all. Thus, e s eed of rotation of the cutter" discs greater t an the'speed of travel of the web is V attained, and the-progressively increasing speeds of the rewinding rollers insures va firmly-{wound set of rewound coils, as has already been explained. a

Owmg to the, larger size and consequent greater momentum of themoving parts in amachine of this type, a braking mechanism is preferably provided which is readily accessible for manual actuation b the operator. This mechanism as'shown in 9 includes a brakeshoe 121 whic is piv'oted on a stud 122 on the framework and is adapted to frictionally engage the periphery of the fly wheel 96 to thereby bring the driven parts to a stop. The brake is pref-- i res 3 and y erably-brought into operative position by means of a hand lever 123 alsopivoted on the stud: 122 and carrying a thrust-transmitting member 124 adapted to bear directly against the brake shoe 121. The member-124= is preferably yieldingly mounted-in a socket 125 in the lever 123, the spring 1126 being arranged to permit themember'124 to yieldwhen an-excessive degree of force is ofiered to the 1 brake lever 123.

In order to hold the brake mechanism normally inoperative, a spring 127 exerts pressure on-.arod 128 which is connected-with a stud 129 pro'ecting from the brake shoe and acts to wit draw the brake shoe from engaging position' when the lever 123 is released. 1

In the practiceof the invention it is desirable to provide means that will co-operatewith the mill roll to produce a constant tension on the web to thereby overcome any tendency that the rotating roll might have to momentarily increase its speed and, by

producing-a slack stretch in the web, inter" fere with the operation of the device.v The plOVlSlOIl of such tenslomng means 15 especially desirable in handling mill rolls of the lar er sizes. bra 'ng mechanism beiprovided which will stop the rotation of the mill roll, and thus preventthe unwinding of a greatlength of web, when the operation of.v the machine is stopped. An example of a combined tensioning and braking mechanism is shown in Figures '1, 4 and 11 of the drawing and takes the form of a band brake comprising apul- 1e or movable member 130, the periphery of which is adapted to be frictionally' enga ed by the brake band 131. The'brake ban is attached to stop members 132 at the lower side of the pulley which engage opposite sides of a tie rod 133 to hold the brake band 131 stationar and preventits be' carried about with t e rotating pulley. e brake band is normally 'set so as to grip the-pulley It is equally desirable that a with suflicient force to maintain the web under tension. In order to pull the ends of-the brake band toward each other to thereby cause the band'to grip the pulley with sufiicient'force to stop the rotation of the roll, that end of the band which passes over the right-hand face of the pulley in Figure 1 of the drawing is secured to. a cross bar 134 having its ends mounted in slots 135 in the side members 136 of the frame designated generally at 137. The other end of the brake band is secured to the rock shaft 138 which passes through the slots 135 and has the cams 139 mounted on its ends outside theframe members 136." The cams 139 engage theshoulders 140 on the frame whenthe shaft is rocked and force the rock shaft 138 and the crossbar 134 toward each other in the slots 135 and consequently pull the ends of the band toward eachother to thereby cause the I brake band 131 to grip the'pulley with sufposite side of the machine.

ficient force to stop its rotation.

' It is desirable to provide a single actuating means for both the brake mechanism of the slitting and rewinding machine c-proper andthe brake mechanism which is especially provided for the mill roll shaft. 'To this end the'rock shaft 138 which rotates the cams 139 to pull the brake band ends together has an arm 141 fixed to one end there- 9 of which is connected through a rod 142' with a corresponding arm 143 rigidly car-.

ried by the rock shaft 144 extending across the machine. The rock shaft 144 thus serves as a medium for connecting the hand lever 123 of the main machinebrake 121, through the arm 145 and link 146, with the mill roll shaft controlling brake band 131 at the op- A weight 148 carried by an arm 147 on the rock shaft 144 tends to move both the braking mechanism to inoperative position and supplements the action of the'spring'127, already referred to, in securing this function.

A coupling member 163 carried by the end of the mill roll 155 has a projecting tongue 164 arranged diametrically across its face which is adapted to fit into the slot 162 of the brake shaft head 161. The tongue 164 has notches 165 out intermediate its ends with which the inwardly extending lugs 166 carried by a locking ring 167 rotatably mounted on the brake shaft head 161 are adapted to engage to lock the tongue 164 against removal from the slot 162. A groove 168 in the coupling head 161 receives the inwardly projecting lugs 166 of the locking ring and not only prevents the'removal of the ringfrom it's head but also provides for the rotation of the ring into and out of locking position.

In order to vary the gripping effect of" the tensioning device 1n accordance with the requirements of different mill. rolls, provision has been made for adjusting the length of the gap which normally separates the ends ofthe brake band.- This adjusting means is best shown in Figures 1 and 4 of the drawing and comprises a screw 149 which is threaded through a seat 150 in the frame 137 and can be manipulated to move the cross bar 134 toward and from the other cross bar 138' to thereby Vary the gripping action of thebrake band. Preferably interposed between the cross bar 134 and the band end which it carries, and the end of the screw 149, is an abutment member 151, slidably mounted on the frame 137 and adapted to transmit the longitudinal movement of'the screw to the cross bar -134. In order to turn the screw; 149, a

hand wheel 152 is provided which operates the screw 149 through the shaft 153 and universal joint 154, the universal joint providing for the 'longitudinaladjustment of the mill roll shaft. The hand wheel 152 is adapted to tilt horizontally about the edges 156 to allow for'the lateral movement of the brake engaging end thereof. It will be seen that, a *combinedtensioning and brake mechanism has been provided which can be adjusted to exert any desired tension on the web during the operation of the machine, and can in addition be manually actuated as a brake to stop the rotation of the roll at thewill of theoperator.

Because of the difficulty of mounting a large and heavy mill roll in correct lateral relation to the operating mechanism, means have been-provided for laterally adjusting the mill roll after it has been put in place in the bearings 157. This mechanism. comprises a rack member 169 mounted on the shaft and adapted to give a longitudinal movement thereto inthe bearing 170. A pinion 171' meshes with the rack 169 and isdriven from a sprocket 172 through chain 173 and sprocket 174. The sprocket 174 is in turn operated through the shaft 175 by I means of the hand wheel 176. It will be the frame-work and at its upper end in a carriages 37 wereadapted to travel.

shown in section in Figure 2 and in elevaf tion-for a-portion of its lengthin .Figure 11, which is adapted to be bowed upwardly against the under surface of the web, .is-

employed. In order that the spreader bar 10, which. is preferably made of resilient and flexible metal, may be adjusted to dif-- ferent curvatures to conform to the requirements of different materials, means are pro--.

vided for bending the bar into the form required. Each end of the spreader bar'10 has a slot 177 therein which provides-for screws 17 8 can be turned in the threaded portions 179 of thebrackets 180 to raise orv longitudinal movement of the'end portions of the bar with relation to the hand screws 17 8 on which they are supported. The hand lower thebar engaging-nuts 182 on the upper ends of the screws and thereby determine the height of the end portions of the spreader bar. The locking screws 183 pass through the brackets 180 and are adapted to bear against the stay bar 184 to hold the brackets in any desired positions along the bar,-while the thumb screws 185 mountedin the lugs 1815on the brackets serve, to lock the screws-178 at any desired heightQ It will be seen that the adjusting screws-178 a'tthe-ends of the spreader bar are adapted to pullthe ends of theb downwardly while the remaining screws pintermediate the ends of the bar are adapted to how. the intermediate portion ,oftthe *bar upwardly. In order to provide for-the engagement of the intermediate screws with the bar to push it upward, the bearing members 186 are swiveled on the ends of th screws and directly engage the undersi'de'of the bar. It will be seen that the adjusting screws. 178 can be. manipulated to give vthe spreader bar 10 any desired curvature'to thereby spread the web and remove any wrinkles or other irregularities therein before the cutting and rewinding operations take place.

It has been found desirable in slitting and rewinding certain materials to providesup- .plemental means for cutting any threads that might be left unsevered by the slitting discs, aswell as to guide the strips and prevent'them from overlapping as they pass to for this purpose.

.tion, one of whic the rewound coils. In Figure 2 of the drawing one of the separating blades 187 is 'shownmounted on a supporting bar 188. in position to engage the slitted web immediately after it leaves the slitting mechanism. In placing the blades in this location and in then causing the slitted web to immediately engage and pass around the rewindingroll -2 a very efiicientcontrol of the strips is retained until they pass into place on the rewound coils. In Figure 13 ofthe drawing the separating blade is shown in a location where itwillengage the web between the rewinding roll 2, which in this caseis the cutter roll, and a guiding roll 191 around which the slitted web is diverted toprovide a stretch in conjunction with which theseparating blades can act. Theguiding roll 191 is preferably removablymounted in bearings 192 provided in the brackets 190 In Figures 2, 13 and 15 an alternative mounting for a series of separating blades is indicated at 189. Separating blades mounted on this support engage the upper stretch of web as it passes from the vguiding-roll 191 to the rewinding roll 2 Attention is also directed to Figures 2 and 13 for a showing of device for diverting thenarrow trimming strips that are severed from the edges of the web, clear of the machine. of shallow sheet metal guiding members,

These devices take the form or troughs, 193- enerally U-shaped in secis so mounted near each side of the machine that they can be moved laterally to positions coincident with the edges of the web. ,Each guiding member 193 is attached to a supporting member 198 slidably mounted on the T bar 26 and to which it can be clamped in any. desired position by means of'the thumb screw 199. The guiding members 193 rest at their lower endson the tie rod 200 in Figure 2 of the drawing. -The receiving end of each guiding member when'in operatlve position is located closely ad acent the trimming strip .c'utter-so as to-receive the trimming strip immediately after it is severed.

A preferred form of driving means for the .machine comprises the gears and Y89 which are mounted on the shafts of the rewinding rolls 1 and 2 and which mesh with 94 which consists of a fly wheel '96 rigidly connected to the gear 94. and having a friction cone flange 97 adapted to co-operate with a corresponding flange 98 on the drive .these members are rotatably mounted is preferably made hollow. The stud shaft 99 is ri 'dl'y held in the framework 101 of the mac ine by means of the set screws 102 -and carries a clutch actuating rod 103 which is attached to a clutch actuating cam member 104 adapted to co-operate with a cam face 105 on the inner end of the stud shaft 99. The other'end of the clutch actuating rod 103 is 106 and a ocking nut 107 through which motion can be transmitted from the rod 103 through the cap member 100 to the driving ulley and clutch member 95 in order to firing the clutch faces 97 and 98 into operative engagement. A push spring 109 bears tends to ress the cap member outwardly and thereby disengage the clutch members. Provision for the control of the clutch by the operator is.made through. the use,.0f a foot lever 110 fulcrumed at 111 in the frame of the machine to move both vertically and horizontally, as shown in Figures 2, 5 and 9.' A chain 112 attached at one end to the foot lever 110 asses over a sprocket 113 on the cam 'mem er 104 and is connected at its other end to a fixed point 114 in the frame. LA pull spring 115 on the side of the pulley where the chain. is anchored -tothe frame provides for a, movement of that art of the chain which engagest-he sproc etand serves to move'the, cam members 104 and 105 toclutch disengaging position when the foot lever is released. A secondsprin 116 inserted in. the chain on the other si e of the sprocket serves to protect the parts ward movement of the foot lever ,1 10'. A lug 117 shown in Figure 9-on the locking plate 118' serves-,to hold the foot lever in its lowermost or" clutch engaging position.
