last full sheet will be completely slit or out before the slitting or cutting cylinders separate further to provide means for individual as well as collective adjustments of the cutting disks on the main shaft of the male cutting cylinder whereby the individual blades may be readily set to obtain accurate cutting or slitting; further to provide novel means for mounting such individual blades allowing for shifting or easy removal of same combined with means for procuring minute relative adjustments for the several blades as well as separate blade adjustments in their indi-, vidual carriers.
My improved attachment also embodies other features of novelty and improvement in combination with slitting, cutting or perforating devices, whereby the operating mechanisms are simplified and made more effective and otherwise better adapted for use, all of which will be hereinafter set forth and then particularly pointed out in the appended claims.
The drawings show my invention in. its preferred embodiment in a rotary press with the slitting cylinder attachment arranged with blades adapted to slit or out a sheet or strip of cardboard or similar stock with eight rows across the sheet requiring seven knives or blades in each row. Such layout for the cutting blades, however, may be widely varied to meet requirements, My improvements, however, are not to be restricted to any particular type of printing-press, since the inwith the same advantages and results.
Of the drawings, Fig.1 is an end view looking from the left in Fig. 2 illustrating more particularly the slitting cylinders and the ghrow-oif device forthe male slitting cylin- Fig. 2 is a diagrammatic view in side elevation, of a rotary printing-press embodying my improvements and particularly illustrating the layout of the slitting cylinders;
F ig. 3 is a detail side view of one of the disks which compose the male slitting cylin- .der, the clamps for holdingthe blades being omitted Fig. 4 is a detail side view illustrating male I p Similar numerals refer to similar parts throughout the several figures.
Referring more particularly toFig. 1, the
Referring to Figs. 1 and 5, the male cutting cylinder 81 is preferably composed of a series of disks 89 slidab'ly mounted on the shaft 90 of the cylinder 81, and preferably secured thereto by set screws which are not shown. Each disk 89 has formed therein a clearance hole 91 to receive a transverse screw-threaded rod 92 on which screw- nuts 93 and 94 are carried on either side of the several disks 89 as shown in Figures 1 and 5, Means are preferably employed to collectively adjust the several disks 89 on the shaft 90, which means may be widely varied in construction. In the present embodiment, two bearing disks 89 are pinned fast to the shaft 90 at either end as shown in Fig. 1, each disk 89 having a clearance hole through which the ends of the rod 92 project, such rod carrying the nuts 93 and 94 on either side of the disks 89 as shown. When it is desired to collectively adjust the disks 89 as a unit, the two sets of nuts 93 and 94 aremanipulated to shift the rod 92 transversely in either direction, while a group adjustment of several disks 89 is attained by loosening the nuts 93 and 94 of the remaining disks and then tightening same after the first set of disks has been shifted as a group. Each disk 89 maybe separately adjusted relatively to its adjacent disks by the sets of nuts 93 and 94 on either side of the disk to be shifted.
Separate means are provided to throw off the cylinder 81 from the cylinder 79. Ac cordingly the shaft 90 for the male cutting cylinder81 is .mounted at both ends in eccentric bearings 95 (Figs. 1' and. 2), which inturn are'mounted in journals- 96 carried by theframe 22. The bearings 95 carry the projecting arms 97 (Fig. 2) to which are pivotally secured the toggle levers 98 pinned f at 99 to the toggle arms 100 mountedon the throw-off shaft 101 ournalled in the brackets 102 secured-to the frame 22% shown inFig. 2.
Means are provided for mounting the individual sets of knife blades or cutterson the cutting cylinders 7 9 and 81 which are shown in detail in .Figs. 3 to 7 inclusive, whereby the individual bladesmay not only be easily removed, but falso be secured on the cylinder 81 by means admitting of minute relative adjustments; referring to Figs. 5 and 6 the disks 89 on the male cutting cylinder carry. the split hou'singsf132, the successive housings 132 beingadjusted relatively to one another by the screws 134 (Fig. 6). Each housing 132 has the cut-out 135 formed in its outer surface to contain and hold the transverse cutter blades 136 maintained between the clamp blocks 137 and 138. The block 138 has a bevel surface 139 on which the wedge'block 140 slides inwardly to bind the blades 136 between the blocks 137 and 138. The block 140 has a hole bored therein through which the screw-bolt 141 extends to engage with the housing 132. The spring 142 is coiled around the bolt 141 and tends to force the wedge block 140 outwardly. The inward movement of this block 140 by screwing in the bolt 141 against the spring 142 binds the blades 136 in position. The longitudinal cutter blades 143 are carried in a suitable groove 144 formed in the periphery of plates 158 on the disks 89, and are adjusted relatively to one another in the grooves 144 by the screws 159 (Fig. 7). The female cutting cylinder 79 has formed in its outer surface circular parallel run-ways 145 in which are adjustably secured the grooved bedplates 146 to coact with the longitudinal cutting blades 143; in like manner the groovedbed plates 147 are also adjustably secured to the cylinder 79 to receive the transverse cutting blades 136, all as shown in Fig. 7. The collective arrangement of the two sets of cutting blades 136 and 143 in relation to the female cutting cylinder 79 is shown in Figs. .3 and 4.
