WILLIAM HEOKERT, OF BROOKLYN, ASSIGNOR TO NATIONAL BANK NOTE COMPANY, OF NEW YORK, N. Y.
PAPER-CUTTING MACHINE.
SPECIFICATION forming part of Letters Patent No. 227,356, dated May 11, 1880.
I Application filed April 4, 1879.
To all whom it may concern:
Be it known that 1, WILLIAM HEGKERT, of the city of Brooklyn, county of Kings, and State of New York, have invented a new and 5 useful Improvement in Paper Cutting Machines, of which the following is a specification, reference being had to the accompanying drawings, forming part of the same, in which- Figure l is an end elevation of a machine embodying my invention. Fig. 2 is a plan of same, and Fig. 3 a vertical section on line so of Fig. 1. Figs. 5 to S, inclusive, are detailed views of parts of the machine which are fully described below.
My invention relates to that class of papercutting machines in which paper is out while lying upon a bed-plate by a vertically-reciprocating knife; and it consists in the devices and combinations of devices hereinafter described and claimed.
The frame of the machine is formed of the two upright sides A A, connected by crossbars A A A and plate A B is the bed,
formed of a plane iron plate strengthened by a downwardlyprojecting rim or flange, a, extending around its outer edge, and also by the cross-rib a and hollow rib B. G is the knifebar to which the knife 0 is secured. The
0 knife is suspended by the links a a to the sliding blocks D D, which are held and fitted to slide vertically in ways between the upright standards E E, Fig. 3, where are shown the said standards on one side of the machine.
3 5 There are similar standards on the opposite side. They form part of the frame of the machine. Screw-bolts pass down through -the plate A one at either end, into female screws in the said sliding blocks D D, whereby the 0 said blocks may be raised or lowered in their ways at pleasure, thereby enabling the knife to be adjusted to the bed. The heads of these screws are indicated by the letters 0 0.
F is the driving shaft, which revolves inboxes I) I). G is a worm-gear secured to a shaft which has its bearing in a sleeve, G. The boxes I) b and sleeve G are supported on or form part of a bracket, H, that is bolted to one side, A, of the frame, the block D being 0 also attached to orformingpart of said bracket. The holes through which the bolts pass that bolt the bracket to the frame are slotted, to permit the bracket to be raised and lowered with the knife-bar. The gear G is driven by an endless screw or worm, c, on the shaft F.
I is a crank-connection pivoted at one end on the crank-pin g, fixed in the gear G, and at the other in the knife-bar O, at g, the end of the said bar being slotted to receive the end of said connection.
It is evident that as the gear is revolved from right to leftthe knife-bar will be re ciprocated horizontally or endwise, and at the same time elevated and depressed vertically by swinging 011 the links a (R.
It is also evident that the upward motion of the knife-bar will be morerapid than its downward movement, as it moves upward while the gear G is making less than half a revolution, and downward while said gear is moving through the remainder or more than half a revolution.
This construction and arrangement ofparts permit the knife and the mechanism which actuates it to be raised and lowered together 5 for the adjustment of the knife to the bed. This arrangement and construction of parts also incidentallyrelieve the general frame from all strain as it is evident that the force exerted through the crank-pin in the gear G and the connection I to draw down the knifein the act of cutting, which force operates to move the bed toward the bracket H, and the said bracket in an opposite direction, will terminate in the side A of the frame to which said bracket and bed are attached.
L is a clutch splined on the shaft F, fitted to engage the hub L of the driving-pulley M, running loose on said shaft, as shown in Fig. l.
L is the clutch-lever, pivoted at h, the upper arm being curved, as shown, so as to be parallel with the knife-bar 0. Through this end i, which is enlarged for the purpose, passes a pin, 0, having a shoulder, t", and head i on the outer end and a collar, t near the oppo- 5 site or inner end.
A spiral spring, j, placed in a recess in the end 5, through which the pin 0 passes, acts to press the pin inward over the knife-bar, but permits it to be Withdrawn so as to clear the said bar.
Now, it is evident that when the knife-bar is raised it will engage the pin 0 in the position shown in Fig. 3, whereby the long arm of the lever L will be carried up with the knifebar and the clutch disengaged from the hub L, and that by this movement the motion of the gear G, and consequently of the knifebar, will be arrested as the bar reaches the upper limit of its stroke. In this position the bar will remain until the pin 0 is withdrawn, and thereby disengaged from the knifebar. When this is done the long arm of the lever L will fall by its own weight, thereby throwing into engagement the clutch L, whereby the gear G and knife-bar will be again set in motion.
By the arrangement of parts described the upward movement of the knife-bar is automatically arrested just as it reaches the end of its upward movement, where it will remain at rest, affording opportunity for the adjust ment of the paper on the bed until again set in motion by the withdrawal by the operator of the pin 0.
J is the paper-clamp, the office of which is to press and hold the paper down upon the bed B while it is being cut. This clamp is secured at its ends to side rails or bars, 1) 19, one of which is shown in Fig. 5, and both are indicated by dotted lines in Fig. 1. They are fitted to slide automatically in ways in the sides A A of the frame. To their lower ends is secured the girt J, through the center of which is a female screw, in which works the male screw B. This screw B revolves in a bearing in a bracket, l bolted to the hollow rib B on the bed B.
K is a shaft, one end of which has its bearings in a bracket, m, also bolted to the bedplate, the opposite end having its bearings Z in the bracket Z as shown.
a is a beveled gear on the shaft K, which meshes into the beveled gear n on the upper end of the screw R.
0 is ahand-wheel on the shaftK It is evident that by turning this shaft K the girt J, and with it the clamp J, may be raised or lowered for pressing and holding the paper on the bed-plate B while being out.
As is shown in the drawings, the shaft K is arranged to extend from one corner of the machine diagonally inward and across to the bracket 1 thus locating the hand-wheel 0 at the right-hand corner of the frame, out of the way of the operator, while it is still in a position convenient to his hand.
l is a second bearing in the bracket P, designed to receive the inner end of the shaft K, if it should be desired to shift the said shaft onto the opposite side of the machine from that shown, the change being made by simply unbolting the bracket m and changing it to the oppositecorner of the frame, screw-holes being prepared in the bed-plate on that side for it.
Fig. 4 is a somewhat enlarged view, in section, of the pulley M, shaft F, and clutch L. If it should be desired to operate the machine by hand, detach the clutch and put a pin through the hole W in the hub L of the pulley and the shaft F.
r 1' are collars secured on the shaft'F by set-screws, or otherwise, for holding the pulley in place on the shaft when running loosely thereon.
A recess, is made in the ends of the hub L next the clutch, in which the collar 0" is placed, thus placing it out of the way of the clutch.
N is the gage against which the paper is to be placed to be out. It is adjustable on the bed-plate by means of the screw-shaft P. This screw-shaft has its bearings at either end in the rim to of the bed B, as seen in Fig. 3, and is furnished with a hand-wheel, a, with which to revolve it.
P is a nut bolted to the gage N, and extending downward through a slot, 8, in the bed, the screw-shaft P working in said nut.
S is an enlarged opening at the end of the slot 8, through which the nut P is passed to its place under the gage N.
B is a hollow rib secured to the bed, which spans the slot .9 and extends from the rear end of the bed to the cross-rib a. A cross-section of this rib is shown in Fig. 8. The screw-- shaft P lies within this hollow rib B.
On Sheet 2 of the drawings is shown the mechanism designed for indicating the adj ustment of the gage N. This consists of dials q q, Fig. 6, set in the bed B,that are revolved by the screw-shaft P. From each dial extends a short shaft, r 1, through the bed, on the lower ends of which are worm-gears s s, that mesh with the screw P. On the dials are index-figures, as shown. It is evident that the movement of the gage N will correspond with that of the dials, and thus the position of the gage in relation to the knife may be correctly indicated by the figures on the dials. One or both dials may be used.
In place of said dials a vertical wheel, t, as
shown in Fig. 7, may be used, a slot being cut in the bed, and the wheel arranged to revolve under the bed, with its periphery in this slot, and just coming through to the upper surface of the bed, the indicating-figures being placed on the said periphery. The wheel is revolved by the screw P, working in a wormgear, 15, on the shaft of the wheel, revolving in brackets c 21, secured to the bed B.
I prefer to employ the two dials represented in Figs. 2 and 6 of the drawings, in order to be able to employ conveniently both the metric and the English systems of measurement, the figures on one dial indicating the metric and on the other the English measurement. If preferred, however, only one dial may be used, and the figures for both systems placed on such single dial.
What I claim, and desire to secure by Letters Patent, is-- 1. In a paper-cutting machine, the bracket H, having formed on it the link-box D, and the bearings b and 1), adapted to support the shaft F, pulley M, and the worm-gear G, all bracket 1 in combination with the shaft K being vertically adjustable on the side of the and bracket m, made interchangeable, so that frame A, as and for the purpose specified. the hand-whee] o andits shaftK may be placed 2. In a paper-cutting machine,the dials q g at the right or left hand side of the machine, 5 (one or both) in the face of the table B, and the as may be desired by the operator, all as de I 5 worm-wheels s s, in combination therewith, scribed.
and with the screw-shaft P, as and for the WM. HEOKERT. purpose specified. Witnesses:
3. In a paper-cutting machine, the screw R, J. P. FITCH, 10 the bevel gear 02, the bevelpinion n, and M. F. CLIFTON.
