COMBINATION sLIT'rEE. AND 'PERF'ORATOR.
, Application filed August 19, 1919. Serial No. "318,586;
To all whom it may concern:
Be it known that I, LESLIE D.'Honr, a citizen of the United States, and a resident of Newark, cou'ntyrof Essex, and State of New Jersey, have invented certain new and useful Improvements in Combination Slitters and Perforators, of'which the following is a specification. i
This invention relates to a combination slitter and perforator'whichcan be used for slitting and for perforating paper while the paper is on the impression cylinder of a printing press, whereby there is an economy of time and of space.
The invention relates to a device of this kind which is adjustable soas-to vary the place at which'the perforating or slitting takes place, according to the make-up of the sheet.
My invention further consists of a device of this kind in which a band, preferably of steel, is employed to provide a shear out where the slitting is being done, the band being adjustable laterally the sameas the cutter, according to the marking on the sheet and the portion to be slitted or cut.
In my improved slitter and Q cutter the band is preferably embedded in the soft material of the tympan, being-held in place at the two ends with the necessary tension,
narrow as one-fourth of an inch wide, as the band can be reduced to this width and still operate efficiently, Embedding the thin steel hand or bands does not in any way interfere with the printing or make-ready.
In this improved construction the perforation or 'cut in the sheet is straight, the alinement being insured since the grippers, as ordinarily, used in cylinder presses, are holding the sheet while the slitting or perforating is being accomplished.
The invention further resides in various details of construction to, be more fully described hereinafter, and in the "combination of parts as is described hereinafter and finally embodied in the claims.
The invention is illustrated in the accompanying. drawings, in which Figure 1 is a sideview, somewhat diagrammatic, of the impression cylinder of a printing press provided with the improved cutting and slitting attachment, the cylinder being shown as provided with a band. Fig. 2 is a perspective view of a fastening means for one end of the band. Fig. 3 is a perspective view showing a spring and hook used for I connecting the end of the bandcto the top sheet reel. Fig. 4 is a side view and Fig. 5 a top view of the tool holder used in conjunction with the band for slitting, and is of the type shown in Fig. 1. Fig. 6 is a side view, partly in section, and Fig. 7 is a top v ew, of a modified form of tool holder. Fig. 8 is a side view, partly in section, of an impression cylinder with modified forms of fastening means for the band Fig. 9 is an enlarged detail sectional view taken on' the plane indicated by line 9-9 in Fig. 8; F 1g. 10 is a bottom view of part of the cylinder shown in Fig. 8.- Fig. 11 isa perspective view of a form of fastening means for'the band illustrated in the top part of Fig. 8. Fig. 12 is a'perspective viewof the fastening means shown in the bottom part of Fig. 8, and Figs. 13, 14 and l5 areperspective views of brackets used for holding the anchor barto which the device shown in Fig. 12-is securedj I The device is used in conjunction with the impression cylinderof a printing press, in the drawing 10 indicating the impression cylinder, and adjacent thereto, and preferably secured to the frame of the printing press, is a rod 11 which issupported by rod supports 11*, one. being placed oneach side of the machine and being-adjustable toward and from the impression cylinder andv being fastened in place by set-screws 13.
Transversely adjustable on the rod 11 is the tool holder 12. As} many tool holders are installed as therears slits. to be made in the sheet. In the end ofthe tool holder, the details of which; will be described hereinafter, is arranged-a wheel-lfwhich can be either a slitting or a perforating wheel,
the illustration showing aslitting wheel 36,
this slitter or cutter operating against the tympan and bearing against the edge of a band 15, which band is usually made of thin sheet steel, rather narrow and easily embedded in the tympan,being held at its'two ends so that it is taut and thus acts not only to guide the wheel 14: but provides,
in conjunction therewith, ashear out which does not at any point tear the sheet, providing a clean out without any frayed or uneven edges. 7 j
In the form shown in Fig. 1' the band is secured at the gripper edge, which in Fig. 1
is the top edge, by a fixture 16, which is shown more particularly in Fig. 2, which has a hooked end; 17 fitting around the bar 18 and providing a grooved hooked end 19 which prevents side movement of the band relative to the fixture, the end-of the band being hooked over the end of the finger 2O 7 scribed hereinafter.
The other end of the band is secured to a spring 22, which is looped, its ends being secured to a' hook 23, which is preferably made of wire and is secured to the top sheet reel or otherwise fastened, the bar 24 in the v drawing indicating an element over which the hook is caught. The hook 23 is slidable on the bar 24 andthe fixture 16 is slidable on the bar 18, so that the band can be laterally adjusted on the cylinder;
i ,A tool holder is shown in detail in Figs.
' 4 and5 comprising the clamping members 24 and 25, one of which, as 25, having the extension 26 and also having a knuckle 27 through which a pin-28 is passed, the pin also acting as a bearing for the knuckles 29 of the rocking member 30, the rocking member havlng a slight rocking mot1on.'be1ng forced in one direction by a spring 31, such motion being limited by the head 32 of the ing means for the bands 15 is illustrated.
set-screw 33.
' The end of the rocking member is forked, providing bearings 34 between which is mounted the wheel 35 and into which is inserted the disk 36', these elements 35 and 36 being the same elements as designated by the reference numeral 14 in Fig. 1. The disk '36 1s either a cutting or slitting disk, or, if
desired, is a perforator, according to the nature of the work to be accomplished. The slight rocking motion of the rocking member permits it to take care of anyslight inequali ties 'in the surface against which it is operating, and also insures sufficient pressure to positively slit the paper sheet. The wheel W 14 includes collars 35,35 flanking the disk 36, thewhole being assembled so that the collar 35 operates against the outer face or surface of the"band, so that mainder andthe band, and
terialon the cylinder is held against the cylat the same time the wheel is positively rotated sothat the disk rotates as it performs its shearing action against the edge of the band. The wheel is readily removable, one form of permitting this being shown in Fig.
5, inwhich the screws 34 are screwed in the bearings 34 and thus support the wheel so that it can be readily reversed to make it adaptable for cuttlng against either edge of the band.
The usual grippers 37, shown in dotted outl ne in Fig. l grip the sheet in the usual way and carry 1t around with the cylinder,
and while it is thus being carried around'the slitting V or perforating operation is accomplished. The band or bands 15, by being embedded in' the tympan, which is of soft matratedas square, and a fixed member 38 is secured bya set-screw 39, which bears against the back ofthe rod 11 and has bearing faces against which the top and forward faces of the rod project with a lug40 pro- 'ectin at an an 'le therefrom and actin as b C; b
a bearing for an adjusting screw'41 which operates in a screw-threaded recess 42 in the sliding member 43, so that the member can beadjusted back and forth, the locking of the sliding member 43 being assisted by the screw 44 which is screwed into the bracket 45 and passes through a slot 46 in the member 43. The guide lugs 47 hold the bracket and the sliding member in alinement, and
the sliding member has on its end a bearing 48 for supporting the slitting or perforating wheel 49.
In Figs. 8 to 10 a modified form of fasten- In this form what might be termed the forward end of the band, or the gripper end, issecured in a bracket 50 transversely movable so as to be adjustable on the bar 51, which bar 51 is secured to arms '52 swinging with the rod 53, the band passing from the bracket 50 half way around the cylinder and being secured by looping it" through the openings 54 and 55 in the fixture 56, which I fixture 56 has a clamping 'member 57 by means of which it is secured to the anchor bar 58 and on which it' can be transversely adjusted. I The anchor bar. is supported by suitable brackets 59, 60 and 61, which havehooked projections into which the anchor bar is seated. The fixture 56 is adjustable-trans versely and is secured in position by the screw62. '7
Other means of fastening the band can be provided, but the illustrated ones are shown to indicate several ways of doing this, the object being to secure a tight, positive positioning of the band in the tympan, the cutting wheel, of course, cutting a slight groove adjacent to the edgeof the .7
band, but operating against the band to provide the shear cut that provides the clean slitting orperforating of the paper.
The part 15 of the band that projects beyond the printing edge of the cylinder, as will be noted particularly in .Fig. 1, provides what I call a starter part which engages the cutter before the cutter reaches the printing edge of the cylinder, and the collar of the cutter, having engaged this band while the cutter is free from any cutting action, initiates the rotation of the cutting wheel so that it is rotating freely when it engages the paper, thus causing a proper initiation of the out without any chance of crinkling or bunching, which might be the result of engaging the cutter before its rotation had been well established.
While in the drawing there is illustrated a slitting wheel with a continuous periphery, it will be understood that in the specification and claims the term slitting wheel also embraces a wheel with a broken periphery, which can be used to make short-spaced slits; in other words,'tomake a perforated line on the sheet.
I claim:
1. A slitting and perforating device for printing presses comprising a cylinder, a band to be affixed to the periphery of said cylinder, and a rotatable wheel having a portion adapted to engage the edge of said band to operate on a sheet being printed, and another portion adapted to engage material on the face of the band to rotate the wheel.
2. A slitting device for printing presses comprising a cylinder, a band adapted to be embedded. in the tympan of the cylinder, and a wheel having a portion to operate against the edge of said band.
3. A slitting device for printing presses comprising a cylinder, a band adapted to be embedded in the tympan of the cylinder, a wheel having a portion supported so as to operate against the edge of said band means for laterally adjusting said band, and means for laterally adjusting said wheel.
4. A slitting device for printing presses comprising a tool holder, means for supporting said holder including a rocking member, means for limiting the rocking motion, means for yieldingly holding the member against rocking, a wheel supported by said member, said wheel including a cutting disk and collars flanking the same and a band on the impression cylinder 0 the press and supported thereon at the periphery thereof so as to operate against one of the collars of said wheel, to rotate the wheel, the disk of the wheel bearing against the edge of the band.
5. The combination of the impression cylinder of a printing press with a band stretched on the periphery of the cylinder, said band projecting partly beyond the printing edge of the cylinder with a wheel operating against the edge of the band, the wheel including a disk, which operates against the edge of the band, a collar which operates against the face of the band, whereby material is held against the band and the wheel is rotated, the projecting part of the band acting as a starter portlon which causes an initial rotation of the wheel before the paperon the press is engaged thereby.
6. A slitting device for printing presses comprising a tool holder having bearings on its outer end, a slitting wheel, means for removably supporting the slitting wheel in the hearings to permit a reversal of the wheel, said wheel including a collar larger in diameter than the bearings, in combination with a band on the impression cylinder of the press, against either edge of which the disk of the wheel can operate, and against the face of which the collar bears to rotate said wheel when in engagement with the band.
In testimony that I claim the foregoing I have hereto set my hand, this 15th day of August, 1919.
