PAPER-CUTTER.
SPECIFICATION forming part of Letters Patent No. 398,575, dated February 26, 1889.
Application filed July 14, 1888. Serial No. 279,970. (No model.)
To all whom it 'may concern:
Be it known that I, ALBERT BEss, of Ilamilton, Butler county, Ohio, have invented certain new and useful Improvements in Paper- Cutters, of which the following is a specification.
This invention pertains to that class of paper-cutting apparatus often called slitters, and designed principally for cutting long webs of paper into narrow pieces, the cutting being done by drawing the paper through rotary shears.
My improvements relate to the mounting of one of the blade-disks of the pair of rotary shears, and are applical'ilo generally where such shears are used.
My improvements will be readily under stood from the following description, taken in connection with the accompanying drawings, in which- Figure l is a side elevation of a paper-cutter embodying my improvements; and Fig. 2, a front elevation of the same, exhibiting the device as being provided with three pairs of slitters, the top slitters at the right-hand end being shown as turned up out of action, and one of the hub-bearings of the left-hand top slitter being shown in vertical diametri cal section.
In the drawings, A indicates housings for the support of the parts7 the special forni of which to be controlled by special circumstances of associationmas, for instance,when the device is to be attached directly to a pa per-1nakin g machine; B, the usual lOWersIitter shaft, to be provided and arranged in the usual manner; C, the lower slitters, to be arranged on this shaft in the usual manner, so as to be adj ustahle along the same, according' to thedesired width of slitting, these slitters being cutting-disks with beveled peripheries, as usual; I), the top slitters, operating in conjunction with the lower slitters, as usual, these slitters consisting, also, of cutting-disks; E, the web of paper to be slitted; F, the saine after slit-ting; G, a non-rotary shaft for the support of the top slit-ters; II, a housing-one for each iop slitter-iu which is journaled the top slitter, this housing being attached to the shaft G by a shank upon the housing securedv in a clamp upon the shaft, the housing i where it receives the slitter having the form of a fork; J, atwo-part col1ar-one for each top slitter-clamped upon the shaft G; K, a cla1np-screw by which the collar J is firmly affixed upon the shaft G in any desired position; L, a clampingsocket formed in the eollar J, opposite to the clamp-screwK, the housing H having a cylindrical shank engaging this socket and clamped therein; M, the hub of the top slitter; N, a bolt carried by the housing` H and forming the axle on which the top slitter revolves; and O, a spring encircling this bolt and serving to press the top slitter toward the bottom slitter, with which it works, this spring being seated in a cylindrical counterbore in one bearing of the housing-fork and compressed between the back wall of the counterhore and the face of the slitter-hub contiguous thereto.
The two-part collar J is clamped tothe nonrotary shaft G by means of the screw K. The forward clamp-socket, L, of the collar holds the housing-fork H. By loosening the screw K, the top slitter (an y one or more of them, of course) may be turned up out of engagement with its lower slitter and there secured in an idle position by retightening the screw K. In this manner the top slitters may be adjusted longitudinally along the shaft to suit the desired width of slitting', and any desired one or more of the slitters may be turned up out of action. If it is desired to entirely remove one of the top slitters with its appurtenances, it is not necessary to remove the shaft G. The two-part collar need only be separated by re moving the clamp-screws at both sides of the shaft G. The making of the clamp-collarJ in two parts is, of course, not essential to the mere operation of the clamp-screw l( as a means for tightening and loosening the clampcollar upon t-he shaft G.
Any given top slitter can be removed Vfrom its housing by removingihe bolt N.
Slitter-faces wear the most atI the extreme periphery of their faces, and they soon lose their clearance and cease to cut properly. They then, as ordinarily constructed, require sharliening. They are generally made more or less concave upon their faces; but this does not correct the evil. In my construction I prefer to concave the slitteudisks as usual,
IOO
but I provide means for compensating for the loss of clearance, and thereby secure an effective operation for a comparatively long time without the necessity for resharpening the slitters. Assume that the slitters are sharp and newly started. The axis of the top slitters Would be parallel with the axis of the lower slitters-that is t0 say, parallel with the shaft B-and in this condition they would Work until Wear materially affeeted the elearanoe at the Cutting-points. Vhen this ooours, I loosen the clamp L and turn the housing H a trifle and reseeure the Clamp. This throws the top slitter out of parallelism with the slitter with which it Works, and in this manner the faces of engaging' slitters may be adjusted i for angular engagement to compensate for the loss of Clearance. is t-he Wear Continues, i the angular adjustment is repeated I olaim as my inventionl. In a paper-Gutter, the Combination, substantiall y as set forth, of a shaft Carrying one or more slitter-disks, and a non-rotary shaft parallel therewith, a slitter-housing clamped to said non-rotary shaft and adapted for longitudinal and rota-ry adjustment thereon, a slitter Carried in said housing and movable axially therein, and a spring engaging said slitter and housing.
2. In a paper-cutter, the combination, substantially as set forth, of a rotary shaft provided with one or more slitters, a non-rotary shaft disposed parallel thereto, a forked slitter-housing clamped to said non-rotary shaft and adjustable longitudinally and rotarily thereon, bolt- N, slitter D, provided With hub M, engaging said bolt, and spring O.
3. In a paper-cutter, the Combination, substantially as set forth, of shaft B, provided with one or more slitters, C, non-rotary shaft G, two -part Collar J, provided With clampsoelet L, clamp-screw K, housing H, engaging said clamp-socket by a longitudinal shank,
g and slitter D, Carried by said housing.
et. In a paper-cutter, the combination, subl stantially as set forth, of shaft B,one or more sli'ters, C, thereon, non-rotary shaft G, two- I part Collar J, clamp-screw K, clamp-socket L,
housing H, slitter D, hub M, bolt N, and spring O.
