PAPER-CUTTING MACHINE.
SPECIFICATION forming part Of Letters Patent NO. 244,938, dated Jlily 26,1881. I I Application filed May 21, 1881. (No model.)
To all whom it may concern:
Be it known that I, EDWIN R. SHERIDAN,
\ of Brooklyn, in thecounty of Kings and State of New York, have invented certain-new and useful Improvements in Paper-Cutting Machines; and I do hereby declare that the followingis a full and exact description thereof,
reference being had to the accompanying drawings, making part of this specification.
Previous to my invention'paper-cuttin g machines have been made in which the clamping-bar,'which"is first forced down onto the thefknifelor shearin'gblade. A machine involvingthis principle'of construction may be seen inj the Letters Patent of the United States grantedltomeMayl25, 1880, o. 227,999.
Mypresent invention relates to this kind of machines; "and it consists in the combination,
with the devices-carrying respectively the clamping-bar and the shearing blade or knife, of an actuating arm orllever pivoted to the vertically-moving frame which imparts the necessary motion to the clampingbar, and provided withfgear-teeth which engagewith a toothed bar hingedto the frame whichactuatesthe knife, the combination being such, as
will be hereinafterfmore fully explained, that the lifting of the free end of said lever will first induce said lever to turn on its fixed fulcrum and operate the clamping-bar, and to their move on its creeping-fulcrum to lift the device to which it ispivoted, and thus operate the knife-frame.
To enable those skilled in the" art to which myinvention relates to make and use the same,
I will now proceed to more fully describe the same, referring by letters to the accompanying drawings, forming part of this specification, and in which- Figure l is a face view or front elevation of V a machine embodying my present improvement. Fig. 2 is a similar view,-but with the moving parts of the machine in difi'erent position. Fig. 3 is another similar elevation of the machine, but with the parts in still another different relative position. Fig. 4 is a detail horizontal section at the line was of Fig. 2. Fig. 5 is a top view.
In the several figures the same parts will befound designated by the same letters of reference.
Ais the table; B, the main frame or sup- 6o porting-stand; O, the vertically-reciproeating clampingbar that holds down the pile of paper to be out, and D the knife frame or stock carrying the shearing-blade d, and having the necessary downward-sweep motion, all constructed and arranged in about the usual man- 'ner,but operated or driven bythe novel means which I will now more minutely describe.
In a suitable stand, E, arranged at one side of the machine, and in the case shown about 7e on a level with the table, is mounted in suitable bearings, the main driving-shaft F, provided with a pulley, G,for the applicationlby a belt) of the motive power. On this main shaft are mounted so asto turn freely,but 7 5 not move endwise, a pinion, b, and half-clutch c, and so as to 'move endwise on it, but not turn thereon, a half-clutch, d, the arrangement of these parts being such that a movement of the half-clutch 01 upon the said shaft 89 F in one direction or the other will either cause any rotation of said shaft to be impartedto the said pinion b or permit said shaft to revolve without turning said pinion; In the same stand E is mounted the counter-shaft H, on which are made fast a spur-gear, I, and a drum or strap-wheel, e, the said gearIengaging with the pinion b, and the said wheel or drum 0 having made fast to its periphery one end of a cord or strap'adapted to'be wound 0 upon said drum, and having its outer end fastened tothe endof alever designed to be lifted, for purposes to be presently explained.
f is a shipper-bar pivoted in a lug, 9, pro
jecting horizontallyfrom aportion of the stand 5 E, and adapted, by a vibratory movement, to move the half-clutch d to throwthe drivingshaft into or out of working engagement with the driving-gears. This shipper-bar is moved by hand in one direction to throw the driving- 10o gears into a working condition, and is automatically moved in the other direction to throw the parts out of gear bya tripping-lever, h, pivoted to the main frame, as shown, and moved by a projectinglug or pin, 1', on one end of the knife-frame.
J is the main working-lever of the machine. It is weighted at its outer or free end, near which the strap or cord 76, by which said endis lifted, is applied, as clearly shown. This lever J is pivoted at s to a vertically-reciprocatory frame, 0, and it is formed or provided at its inner end with a toothed sector or segment of a gear, M, which engages with a rack, N, cut on or attached to apendent arm, P, that is pivoted or hinged at t to the vertically-reciprocatory frame P.
To insure the retention in gear of the sector M and the hinged rack N, these parts are clasped at theirmoving points ofcontact by the armsff' and f of a carriage, provided with anti-friction rolls that hear, one of them against a flange, i, of the sector, and two others of them against the back side of the pendent arm P.
To prevent undue pressure on the teeth of the rack and sector endwise, and keep these devices properly in engagement without undue friction, I provide the sector at each side with a curved bearing flange or surface, m, which rolls against a straight bearing-surface, 11 of the arm P, as most clearly exhibited at Fig. 4.
The frame P is rigidly connected by side bars, g, as shown, to the elamping-barO, which is thus caused to move always with said frame.
Q is a bent lever, pivoted near its angle by a pin, 1, to the main frame, and having itslower end connected by a pin-and-slot connection to the lower middle part of frame 0, whileitsupper end is pivoted to one end of a connectingrod, m, the other end of which rod is connected ata to the knife-frame.
Inthe operation of the machine, the power being applied by a proper movement of the shipper handle or bar, the rotation of the strapwheel or drum winds up the cord or strap k, and thereby the weighted end of lever. J is lifted. During the initial movement of said lever it turns or vibrates on its pivotal point 8 as a fixed fulcrum, and by the vibratory movement of its sector M about the point s causes the toothed arm I? to be pulled down,therehy depressing the frame P and bringing the clamping-bar 0 down onto the pile of paper resting on the table A. When this bar 0 shall have come to a solid bearing on-top of the pile of paper, so. that the frame P and rack-arm P can no longer move on, the continued ascent of the weighted end of lever J causes said lever to then vibrate about the point of engagement of itssector M with the rack N, the engaging It will be seen that by the employment of the lever J, pivoted to the frame 0, as described, and provided with a sector, M, to engage with the rack N, the clamping-bar G is quickly brought to a bearing on the paper to form a point of counter-resistance, as usual, to the power to be applied to do the cutting, and that the cutting device is then actuated by aslower movement of the lever, but with a more economical and effective application of the motive power applied to the machine, since, by reason of the ascending or climbing movementof the toothed end of said lever, the pullon its outer free end is always more nearly in the direction of movement of that end. ,During that part of the motion of lever. J in which itswings from its toothed end as a creeping-fulcrum the arm P, of course, vibratesabout itspivotal connection t sufficiently to perlnit the-frame 0, which is attached. by a fixed pivotal; point, 8, to said lever, to move up. in a vertical. right line, and during themovementtogether of the said arm P and the -sector..M these parts .are held toward each other by the ,claspingecarriage above referred to, which movestautomatically to adjust itself tothemotionof the 5 RE. SHERIDAN.
