CUTTING. DEVICE.
SPECIFICATION forming part of Letters :Patent No. 546,607, dated September 17,1895.
i Application led March '7, 1895. Serial No. 540,871. (No model.)
.To all whom it may concern/.-
Be it known that l, CHARLES A. BYRD, of Drain, in the county of Douglas and State of. Oregon, have invented a new and Improved Cutting Device, of which the following is a full, clear, and exact description.
This invention relates to an improved cutting device, which is particularly well adapted to truly cut the edges of paper or pasteboard ers, who occasionally need a paper-cutter and do not care to invest a considerableA amount in an expensive machine of the indicated character.
The invention consists in the construction and combination of parts as is hereinafter described and claimed.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.
Figure lis a side view of the machine with parts adjusted to receive material that is to be cut. Fig. 2 is a partly-sectional view of the opposite side of the machine, showing a paper-clamping device which embodies fea-v tures of the invention; and Fig. 3 is a trans verse sectional view substantially on the line'` e s in Fig. 1.
A base-plate 10 is provided for the support' of other parts of the cutting device and at' tachment of the complete machine on a heavy.
table, bench, or other stable support by bolts or other means. width are afforded the base-plate for the re. ception of a housing-frame, which comprises four posts 11 and a cap-piece 11a, and thesev parts may be integrally formed together and with the base-plateior separately, as maybe.
preferred. The four posts are so spaced apart in pairs that the cutting device proper may -be located and freely work between them longitudinally of the machine.
A sufficient length andk The cutter-blade 12 consists of a metal plate, preferably steel, rectangular in form and having its lower edge sharpened by beveling this straight edge from one side of the blade, as shown in Fig. 3. A supporting-stock 13 is provided for the cutter-blade, having one side at the lower edge rabbeted, of a suitable width for the reception of the cutterblade, the upper edge of the latter having contact with the shoulder produced bythe formation of the rabbet, and the blade and stock are secured together, preferably by screws, to permit a detachment of these parts. It is essential that the cap-piece 11 be made strong enough to sustain upward strain without deiiection, and it may be, and preferably is,thickened toward the center from each end for the purpose mentioned. A longitudinal slot of suitable length is formed in the cappiecella for the reception of the bell-crank lever 14, that is pivoted in the slot by a pintle-b'olt 15,'which engages a transverse vperforation .in the cap-piece, and also a perforation formed in the lever at the junction of its long and short limbs, as shown in Fig. 1.
vThe longer limb of the bell-crank lever 14 projects above the cap-piece 11a, and its short limb 14a is downwardly extended, its lower extremity being pivoted to the upper edge of the stock 13. A knuckle-jointformation is preferably produced between the end of the -limb 14Ea and the knife-stock 13, so that the circular edge of the lower extremity of said limb may be partly embedded in corresponding recesses in the stock, and thus afford such acontact of these parts as in service will re' lieve the pivot connection of said parts from strain, the thrust of the lever in action being vmainly sustained by the knuckle formation l that is of the usual construction, as indicated in Figs. 1 and 3. Near each end of the cap'- ypiece 11a two similar link-bars 16 are pivoted by their upper ends in the longitudinal slot in said cap-piece, as shown in Figs. 1 and 2, their lower ends being pivoted by knucklejointV formations to the upper edge of the lieve their pintles from bending strains. The links 16 and lever-limb 14.a incline in the same directionv when the knife blade and stock are raised from the base-plate, and it will be seen that a rocking movement of the lever 14 in direction of the curved arrow in Fig. 1 willproject the stock and blade downwardly substantially parallel with the base-plate 10, so that the sharp edge of the blade will be caused to engage with a strip 10a, of slightly-yielding material, which is preferably held in place beneath the knife by its embedment in the upper face of the base-plate, as shown in Fig. 3. There is a clamping attachment provided for the paper-cutting machine to retain material rmly in place while being operated upon by the cutter-blade, the said attachment consisting, essentially, of the followingdescribed parts: A heavy presser-block 17, having a straight lower face, is loosely entered at its ends in upright grooves 11b, formed to receive said ends in two of the posts 11, which are in the same vertical plane, and at the upper ends of these grooves lateral notches are formed in the outer sides of the posts, so as to permit the insertion and also the removal of the presser-block by withdrawing its ends through said notches, one notch being shown at 11c in Fig. 2. At or near the longitudinal center of the presser-block 17 a guide-rod 18 is erected on said block, and preferably it is made adjustable in the latter by its sliding engagement with a vertical perforation in the block, as indicated at 17n in Fig. 3. A screw-threaded clamping-bolt 17, having a grip-piece on its outer end, has a threaded engagement with a tapped perforation in the outer side of the block over the guide-rod and serves to temporarily secure the rod within the block, and the guide-rod projects loosely through the cap-piece 11 of the housing-frame. There is a presserarn1 19 loosely secured near one of its ends on the guide-rod 1S by an engagement of the latter with the wall of a vertical perforation formed in the arm, a clamping engagement of the edges of the perforation at opposite points on the guide-rod being enforced by the spring 20, which is preferably in plate form and is secured at one end to the cap-piece 11 so that its free end can upwardly press on the adjacent end of the arm 19, whereby the presser-arm is slightly depressed at its opposite end and the bite of said arm on the rod will retain it at any desired point of vertical adjustment on the guide-rod. An upward extension is formed on the presser-arm 19, which may loosely slide in the slot 11, formed to receive it in the cap-piece 1l, as represented in Fig. 2, and a hook-nose 19a is produced on the extension of said arm and has engagement with the toe 2liL of the angular bent lever 21, that its toe 21a will be maintained with the hooknose 19n and the lever by a rocking movement of its main limb in direction of arrow 2 (see Fig. 2) will engage its lower edge with the top edge of the presser-arm. The lower edge of the toe-piece 21 is curved, so as to produce a cam formation eccentrical with regard to the pivot 2lb of the lever 21. Hence if the lever is rocked into the position indicated by dotted lines in Fig. 2 the presser-block will be correspondingly depressed and the material on the base-plate 10 will be firmly held in a compressed condition.
It will be evident that by the peculiar construction of the clamping attachment which has been described any thickness of material within the range of the device may be firmly clamped, be it a single sheet or a number of pieces, forming considerable bulk. Vhen paper or pasteboard stock has been clamped in position for cutting, the rocking movement of the lever 14 to effect a depression of the knife 12 will produce a longitudinal movement of the said blade after it impinges the clamped material beneath it.
The-link bars 16, together with the short limb of the bell-crank lever 14, will exert a powerful pressure, as these members of the machine serve as toggle-levers while approaching a perpendicular position, and the body of material held beneath the sharp edge of the cutter-blade will be smoothly and easily sheared into pieces, the exertion of manual force required being comparatively moderate. After material has been cut by the machine, said clamped material may be released by rocking the lever 2l in a direction away from the hook-nose 19, as this movement of the lever will cause its toe 21a to lift the engaged end of the presser-arm 19, thereby releasing the perforated end of the lever from its clamped engagement with the guide-rod 18, so that the presser-block 17 maybe upwardly moved for release of the clamped material.
As the main portions of the cutting-machine can be formed of cast metal, such as iron or low-grade steel, the cost of production can be reduced to a minimum amount and the improved machine be afforded at a low cost.
Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination with a supporting frame, of a cutter blade, mechanism for imparting a vertical and lengthwise movement to said blade, the presser block, an upright adjustable guide rod therefor, a lateral presser arm adjustable on the guide rod and having a hook-nosed extension, means for holding the presser arm in yielding tilting contact with the arm, and a lever having a cam-shaped cnd to engage and operate the presser arm and block, substantially as described.
2. In a cutting device, substantially as described, the clamping attachment comprising a presser block, an upright guide rod thereon, alateral presser arm adjustableon the guide IOO IIO

rod, and having a hook nosed extension, means for holding the lpresser arm in yielding biting contact with the arm and a lever having a cam-shaped end to engage and operate the presser arm and block, substantially as described.
3. In a cutting device, substantially as de scribed, the clamping attachment, comprising a presser block loosely engaging its ends with grooves in the cutter frame, and vertically perforatednear its center, a guide rod adjustably held in the perforation in said block, a presser arm having an adjustable clamped connection with the guide rod and provided with an extension at one end having a hook 15 nose thereon, a spring adapted to enforce an interlock of the presser arm with said guide rod, and a cam lever pivoted on the cutter frame, and having a toe engaged with the hook nose on the presser arm, which arm is dezo pressed When the cam lever is rocked toward the hook nose, as specified.
