MACHINE FOR JUSTIFYING MATRIX-STRIPS.

PECFICATION forming part of Letters Patent No. 311,400, dated January 27, 1885.

` Application filed March if), 1883. Renewed November 12, 1884. (No modeh) To @ZZ whom/ may concern:

Be it known that I, JOHN H. VVIHTE, of Vashington, in the Districtof Columbia, have invented certain Improvements in Machines for Justifying MatrixStrips, of which the following` is a specification.

This invention relates to a machine for justifying that class ot' matrices for producing printing-bars which consist of a narrow strip Io of paper or like material having characters indent-ed or impressed in a single line therein.v

The present machine is designed as an im provement on the one for whichIled an ap- 'plication for Letters Patent of the United States on the 28th day of February, 1883, and, like the original machine, is designed to incise the edges of' the matrix-strip and drawthe saine together endwise at the point of incision, so as to reduceits length and at the same time 2o produce a rib or elevation thereon.

' The improvements consist, more particu- Vlarly, in the combination, with a fixed notched support, of an incising-knife which acts from above; in thc combination, with the above, of

abending device or anvil which acts from below; in the combination, with the support for the matrix-strip, of clamps which engage the matrix thereon and then approach each other to reduce the length of the matrix; in the method of shortening the matrix, consisting in grasping the same on opposite sides of a given point and forcing it together to double or shorten the intermediate portion 5 in various minor combinations of devices; in pecu liar mechanism for operating the knife, the clamps, and the anvil, as hereinafter detailed and claimed.

Referring to the accompanying drawings, Figure l is a view of the matrix-strip, showance before and after justication. Fig. 2 is a perspective view of the operative parts of my'improved machine. Fig. 3 is a vertical transverse section of the same on the line xx, Fig. 4. Fig. 4 is avertical section on the line y y of Fig. 3. Fig. 5 is a face view of one of the operating-cams. Figs. 6, 7, 8, and 9 are detail views illustrating the forms and various positions of those parts which act directly npon the matrix-strips.

Referring to Fig. l, it will be seen that the matrix'stri p therein represented consists of a narrow strip or ribbon of paper or similar material having letters or characters from which a cast is to be taken impressed or indented therein in a single line. It is the object of this machine'to forni in the edges of said strip at suitable points incisions a, and force the material on opposite sides of said incision together endwise in such manner as to shorten the strip and produce raised ribs or projections Z) thereon, as more fully described in my original application above referred to.

The present machine consists offour leading parts-a iiat bed or guide, A, over which the 65 matrix-strip is passed and bywhich it is supp0rted;a vertically-moving knife, B, designed to incise or nick the edges of the strip; a verticallyioving anvil, C, which rises beneath the strip from the center of the support A, to 7o bow or bend the strip upward at the point of incision, and two vertically and longitudinally moving clamps, D, designed to engage the strip on opposite sidesof the anvil and draw its ends together on opposite sides of the point which is elevated bythe anvil.

The guide or support Aconsists of two bars having flat upper surfaces of a width equal to the matrix-strip. The two bars are secured rigidly end to end inline with eachother, and have their inner or adjacent ends notched or recessed vertically on opposite sides, as shown at a', Figs. l and 6. These recesses correspond in size and form with the incisions or notches which are formed in the edges of the matrix- 8 5 strip, and are intended to receive the lower cutting end of the incising-knifc B,`which, descending from above through the matrixstrip upon the supportsA A, forms the notches or incisions in the two edges of the strip simul- 9o taneously, as represented in Fig. 7.

The anvil C consists of a thin blade arranged to slide vertically between the inner ends of the supports A, the width of this blade being equal to` that of the reduced or nicked ends of the support, as shown in Fig.

6, in order that the forked end of the incisingknife may embrace or straddle the same in its descent.

The jaws or clamps D consist each of a 10o plate having substantially a n form incross section. They are made of suitable width to cover the top of the matrix-strip, and extend downward past the two edges of the same and past the two edges of the guides A, to which they are loosely connected, as hereinafter described. These clamps are located on opposite sides of the incising-knife and anvil. In operation they are drawn backward from each other, then caused to descend upon and clamp the strip, and nally moved inward toward each other in order to crowd the two ends of the strip toward each other.

The action of the devices is as follows: The incising-knife is first elevated, and the anvil lowered until its upper end is flush with the top of the supports A. The jaws D are also elevated and moved backward from each other, the parts presenting the positions represented in Fig. 8. The matrix-strip is then introduced between the upper surface of the supports A and the under surface of the clamping-jaws D. The knife B descends, as in Fig. 7, and incises the two edges of the strip, and is immediately raised to its original position. The jaws D then descend upon and engage with the strip, and immediately commence a movement inward toward each other. During this movement of the jaws the anvil C is elevated in such manner as to act upon the under side of the strip between the incisions in its two edges and force the same upward between the two ends of the clamps or jaws in the manner indicated in Fig. 9. After thusn elevating the strips, and before the jaws have completed their inward movement, the anvil recedes, and the jaws, continuing their motion, close the elevated or folded portions of the strip closely together, the same operation causing the opposite edges of the incisions to meet closely.

Having thus described the leading features and their general mode of operation, I will describe the details of the mechanism by which said parts are supported and operated.

The supporting and guiding surfaces A are secured rigidly in position in or upon a bedplate, D', which is preferably grooved to receive them. The incising-knife B is attached at one end to a vertical rod, E, extending `through the bed-plate, and guided at its lower end thereby, its upper end being sustained and guided by a bracket or standard, F, bolted firmly to the bed-plate, as shown in Figs. 2 and 4. The knife is guided and prevented from swinging laterally by means of a vertical slot formed in the face of the standard, and through which the knife is extended, as shown in Figs. 2, 3, and 4. l

To the upper end of the knife-carrying rod or spindle E, I apply a spiral spring, G, resting at its lower end upon the standard, and acting at the top beneath avcollar on the spindle to elevate the knife when it is released. I also apply to the knife-supporting spindle a second spiral spring, II, bearing at its upper end against the under side of the standard F,

and at its lower end against a collar upon the spindle. This second spring, which is of comparatively short` length, tends to check the ascent of the knife after it has risen some distance above its operative position. The two springs applied as above tend to counteract each other to a limited extent, and the result is that when free from other influences the knife assumes an intermediate position, as shownrin Fig. 4, being capable of rising and falling from said position under the action of devices which will be hereinafter described. This application ofthe springs is made for the purpose of enabling the knife-operating cams, hereinafter described, to act in the proper manner. v

For the purpose of depressing the knife, I mount transversely in arms depending from the bed-plate a transverse shaft, I, provided with a sector-plate, J, which plate carries a fixed laterally-projecting cam, K. (Plainl y represented in Figs. 3 and 4.) A spiral spring, L, extended from thel'ower edge of'thesectorplate to a fixed connection on the under side of the bed-plate, tends to turn the sector-plate backward to the left and hold the same in the position indicated in Fig. 4. A rod, M, connected to the upper edge of the plate and extended thence downward to a treadle, foot-lever, or other operating devices, serves as a means by which the plate J may be turned forward to carry the cam K past the side of the anvil-bearing spindle E. The spindle is provided on one side with a stud or pin, N, as

represented in Figs. 3, 4, and ll, in such position that as the sector-plate J is moved forward in the direction indicated by the arrow in Fig. 4 the cani K will be caused to engage above the stud N and depress the same, thereby forcing downward the spindle E and causing the incising-knife D to act upon the matriXstrip, as before explained. The plate J is moved forward a sufficient distance to carry the cani K past the stud N, thereby releasing the latter, whereupon the spring G, which was compressed by the descent of the knifesupporting spindle, immediately elevates the spindle and knife to their original positions, the stud N being carried upward past the rear end of the cam K, after which the cam-bearing plate J is turned backward to its original position.

Inasmuch as it is necessary to have the stud N stand normally below the point of the cam K preparatory to the action ofthe latter thereon, it is necessary to have the spindle E, upon which the stud is carried, descend slightly after the cam has moved backward. It is to secure this action that the second spiral spring, H, before alluded to, is applied. The stud having been acted upon by the cam and having been carried upward in rear of the same, as before described, the cam, in passing backward, rides beneath the stud N, which rides over its upper surface. The cam is eccentric upon its upper edge, and in passing backward IOO IIO

beneath the stud forces the same, together with its spindle, slightly upward, therebygcompressing the spring H. As soon as the cam has been carried backward clear of the stud N the spring H, reacting, depresses thespindie and stud to their normal position, (represented in Fig. 4,) the stud standing at a suitable point to be engaged beneath the cam as the latter moves forward. It will thus be seen that the stud passes beneath the cam as it moves forward and over the same as it moves backward, that the stud is depressed below its normal position by thev forward movement, elevated above its normal position by the backward movement of the cam, and that after the backward movement it again descends to its original positiomas shown in Fig. 4. While the spring G serves to sustain the knife in its elevated position, and under ordinary circumstances to elevate the same whenever it is relieved from the depressing action of the cam K, there is a liability of the knife binding in the matrix-strip and failing to ascend under the action of the spring. To remedy this difiiculty and to insure the positive elevation of the knife, I mount upon the shaft l a second sectorfplate, O, (plainly represented in Figs.

2, 3, and 5 and in dotted lines in Fig. 4,) having on its forward face an inclined surface, P, designed to act against an arm, Q, projecting laterally from the knife, as plainly represented in Figs. 4 and 1l. The parts are so adj usted that alter the depressing-camK has ceased its action upon and passed the stud N theincline P rides beneath the arm Q; and thereby forces the knife-bearing spindle upward in a positive manner.

Passing next to the vertically-moving anvil and its connections, it will be seen on reference to Figs. 3 and 4 that the thin blade of the anvil is secured at the lower end to a stop or guide, R, guidedatv the upper end in an opening in the bed-plate and at its lower end in a depending arm or bracket, S. On one side this stop is provided with two projecting pins or studs, T and U, located one above the other. The upper stud, T, serves as a means of elevating tne anvil, and is acted upon by aspringA cam, V, consisting of an elastic plate secured at one end to the periphery of the sectorplate O, and provided at the opposite free end with a laterally-projeoting eccentric lip or portion, as clearly represented in Figs. 4 and 5. This lip stands in such position that as the plate O is turned forward the lip rides beneath the pin T, as represented in Fig. 5, forcing the same upward, and thereby elevating the point of the anvil between and above the paper-supports Ain such manner as to bend the matrixstrip upward, as before described, and as represented in Fig. 9.

For ,the purpose of depressing the anvil after the action of the elevating-cani V, a fixed cam, W, is applied to the said plate O, as represented in Figs. 4 and 5. This cam, located in rear of the cam V, engages the stud U, and thereby depresses the anvil during the forward mot-ion of the plate O. During the backward motion of the plate the rear end of the elevating-cam V yields and rides above the lelevating-stud T, and before the completion of the backward movement springs downward to its original position. It will thus be seen that by means of the cams V and W the anvil receives positive upward and downward movements. These cams are so located with reference to the cams by which theincisingknife is operated that the action of the anvil occurs after the elevation ofsaid knife. l

Passing next to the clamps or jaws D and the appliances for operating the same, attention is directed particularly to Figs. 2, 3, 4, and 10.' Each jaw or clamp is made, as before stated, of a n form. At its rear end it is held and guided by means of studs c, passed through its depending jaws and seated loosely in longitudinal grooves d in the sides of the stationary paper-support A, this connection permitting the clamp to slide endwise upon the paper-support and also to rise and fall at the inner or forward end. The plates are caused to rise and fall at the free end, and are held down upon the `matriX'sti-ip during the forward motion by means of studs e, secured to the paper-support A, and extending out ward through slotsf, formed in the depending sides of the clamps.l These slotsf have their outer or rear ends extended horizontally and their forward ends inclined downward and forward, as represented in Fig. 2. The resuit is that when the clamps are in their outward position the studs e rest in the lower IOO ends of the slotsf, holding the clamps in an which the studs, passing intoV the horizontal portions of the slotsf, retain the clamps in theirdepressed position as they move forward toward each other, thus causing them to engage the matrix firmly-on opposite sides of the anvil and crowd the two ends or portions positively toward each other as the intermediate portion is elevated by the action of the anvil. Thelongitudinal motion ofthe clamps V is secured by means of two vertical levers. X, which are mounted on horizontal axes below the bedplate and 'extended upward through the same, their upper ends being forked and arranged with transverse pins Y in the under side of the respective clamps, as shown in Fig. 3. The pins Y pass transversely and loosely through slotsor openings in the under side of the paper-supports A, as

shown in Fig. 3. thus serving the additional purpose of limiting the upward motion of the clamps. Springs Z, secured firmly to the lIO ISO

Vatraco and thereby forcing the two clamps down- -ing the descent of the anvil C, their action continuing after the anvil has been depressed, in order to effectually close the folded or elevated portion of the matrix-strip. Frein the foregoing` description it will be seen that the incising-knite, the anvil, and the clamps are all operated by means ot' the cams applied to the two sector-plates J and t).

While it is preferred to retain the details of construction herein described, it is manifest vthat the mechanism for imparting motion to the knife, anvil, and clamps may be modifiedin various details which will suggest tl1en1- selves tothe skilled mechanic without departing from the limits ot' my invention.

While it will be necessary in most cases to incise or notch the edges of thematrix-strip, as herein described and illustrated, the ineisions may bein special cases omitted and the strip' shortened by folding the saine upward and drawing the same together on opposite sides ofthe folded portion. In such case the incising-knife may be omitted and the anvil or bending device used in combination with the movable jaws or clamps.

I do not claim, broadly, herein'the method ofjustifying a matrix-strip by causing its two ends to approach each other in the manner set forth in the application iiled by me on the 23d day otl February, 1883, No. 85,937. The method of justifying herein described differs from that in the application named, in that vunder the former method strips were shortened by bending or raising them upward at intermediate points in their length, thereby drawing the two ends together, while in the present instance the strip, grasped at two points, is forced together from opposite directions, thereby causing the intermediate portion to be raised or upset.

I do not claim in this applicationany features which are described or shown in the prior application above named.

I do not claim herein the matrix-strip having the characters therein as shown, the same being claimed 1n another application numbered 93,064.
