To all 'whom t may concern.'
Be it known that I, FRANK JoHANNEsEN, of Erie, county of Erie, and State of Pennsylvania, have invented a new and useful Im provenient in Linotype-Machines, of which the following is a specification.
My invention has reference to that class of machines in which slugs or bars, bearing won oneedge the characters to print an entire line, are cast in a slotted mold against a co1nposed line. of matrices presented temporarily thereto. i
It is intended more particularly for use in those machines in which the mold is carried by an intermittingly rotated disk, by which it is presented alternately at the casting position and the position to permitejection of the slug. 1 l,
vThe aim of the invention is to provide the instantaneous and accurate adjustment of the mold slot so that it may be caused to produce slugs of any length or thickness demanded. The mold consists mainly of a body portion and a parallel cap portion, be'
tween which the slot'or mold proper exists, the distance between them being variable to change the thickness of the slugs produced; and of a series of independently movable transverse `slides or liners to`y close the mold slot at one end, thereby reducing its length and the'length of the slugs produced.
l combine with the above parts, which are mounted on' the rotating disk, manually controllable mechanism by which the number ot' liners in use may be controlled to regulate thc length ofthe slug., and by which the .distance of the cap from the bo'dy may be controlled to vary the thickness, each of these adjustments being independent of the other, so that the slugs may be varied either in length or in thickness, o1' in both.
l also provide means for adjusting the jaw for conininethe'matrix line and conneetl the same wila the mold-adjusting devices so that the adjustment of the mold to a given length will beaccom anied by an adjustment of the jaw to con nea matrix line ofequal length.
l also connect the-mechanism for adjust- L ing the width of the mold slot with means for adjusting the slug-trimmingknives, so that the latter are automatically adjusted to correspond with the thickness of the slugs produced by the mold. Themanual devices for effecting the adjustments, Aare mounted on the main-frame and arranged to coperate with a mold and its adjuncts on the rotary disk when required.
ln the drawings,-Figure l is a front elevation o'f the-mold-carrying disk and Aad- 60 jacent parts, portions being broken away lto show the internal construction. Fig. 2 is a horizontalA central section of the parts shown in the preceding gure. Fig. 2A is a section on the same plane as Fig. 2, but with the liners disconnected from theactuating slide. Fig. 2B is a rear elevation of the series of liners, with the vertical rack-bar by which they are thrown into and outof engagement with their actuating slide. Fig. 3 is a face 70 view of the lmain slide for throwing the se- -lected liners into and out of action. Fig. 4 is a horizontal section of the same on the line 4 4, Fig. 8. Fig. 5 is a Vertical section on the line 5-45, Fig. 3. Fig. 6 is l.a 75 l perspective view of detached parts.
Referring to the drawings, A represents the vertical intermittingly rotated disk, in, which the mold mechanism is carried, this disk being provided on lthe outer edge with gear teeth through which it receives motion, as usual.
B is Ithe central horizontal shaft on which the disk is supported.
C is a horizontal sleeve sustaining the$ shaft and forming part of a .horizontal slide which is moved forward and backward in the main-frame, as usual, in order to move the disk A and the mold therein facewise to and from the matrix line in a manner well understood in the art.
D and D? are two parallel plates rigidly secured to the disk and forming the body portion of the mold. j E, E, are a series of parallel liners ar- 95 ranged to slide 'independently transversely of the mold body, with their outer ends fiattoned so that they may be drawn back to common plane to serve jointly as one side or wall'of the mold slot. Any number of 109 these slides may be advanced beyond the others across the mold slot to reduceits length. as will be hereinafter more fully eX- plalned. v
F is a mold cap having a Hat face lyi parallel with the ends of the liners aiicgl forming one wall of the slot ormold proper G, in which the slug is cast. y
H, H, are'l .two rigid plates extending be yond the body of the.mold,.and forming the 11 CJR ends of the mold slot when it is adjusted to its maximum length. These end plates H are grooved and serve as guides for the mold .cap F, which is lmovable to and from the ends of the retracted liners in order to vary the width of the slot and the thickness of the slugs produced, in a manner which will be hereinafter explained. When all of the liners are retracted toward the body portion, a slug of maximum length may 'be cast, 'extending across the ends of the entire.
series of liners from one yof the end plates H to the other. Any number of the liners, which are of an em pica in thickness, or vof any other desired thickness, may be advanced endwise against the cap, beginning at one end of the mold, the effect of each liner being to reduce the length of the mold slot an amount equal to the thickness of the liner. In other words, the advance of each liner will reduce the mold and the resulting slugs one em in length, so that a slot for slugs of any length may be produced by simplypadvancing the required number of liners. y f
In ordenthat the operator may instantly adjust the Amold for a slug of any given measure by advancing the requisite number of liners, I provide the following mechanism.
I mountinv guides on the mold disk. a
sliding plate I, movable forward and backward lengthwise of 4the liners, or in other words toward and from the mold cap F, and on this plate I mount a stud i extending into a cam groove a" in the non-rotatingV sleeve C, so that each time the mold disk A is revolved, the;.:eam causes the slide I to move backward or inward radiallyton the disk. Between disk A and slide I, I seat spiral springs @'10 (Figs. 1 and 3), bearing at opposite ends against said parts respectively, for the purpose of u rging the plate endwise on the disk toward the mold cap F. Each of the liners E is jointed vertically midway of Vits length at e, and its rear end e is formed on `opposite sides with vertical shoulders e2 and e3. The Vslide I is provided, Figs. 2,-2A, 3 and 4, with a plate or shoulder 4 to act -against the rear ends of the liners and 'push them forward against the mold cap F, and it is also provided with a shoulder 5 to effect the retraction of the liners when their rear ends e are shifted to engage therewith. a Comb-springs i, attached to the slide I, act against -the lrear ends of the liners and tend to throw themklaterally out of the path of the shoulders a" and i5, Vas shown in Fig. 2A. Whenever one of these springs is permitted to act, the corresponding liner in the retracted position` has its end e thrown sidewise so as to engage behind the body D', as shown in' the slide I, s o that although the slide may be carried forward, the liner will be permitted to remain at rest in its backward position. Thus it will be seen, the advancing slide serves" to. push' forward across the mold slot only those liners whose rear ends have been pressed sidewise into the path of the shoulder i4.
In order to determine the number of liners which will be advanced across the slot, I provide a vertically sliding rack-bar J beveled at the upper end, as shown in Fig. 2B, mounted in the Vmold body and adapted to ride across the ends of the liners on one side and press them backward laterally and successively in position to be acted upon by the pusher slide I. This rack-bar, shown in detail in Fig. 2A, is adjusted by a gear K, mounted to turn loosely the mold disk, and receiving motion in turn on the shaft B of l from an idle gear L mounted on the mold disk, the arrangement being such that the arts will all rotate together and the seected number of liners remain -inv action until the adjustment is changed by theoperator through parts located on the main frame. v
For the purpose of effecting this adjust-l ment while the mold disk is at rest, I provide the pinion M, designed to engage the idler L, and mounted on a horizontal shaftl N, seated-in the main-frame and provided at its forward end with a graduated index wheel O, adapted to be turned b hand.
The shaft N is movable eh wise in its bearings, and is held normally forward by a spring n which keeps the gear M nor- Amally vout of the path of the idle gear L.A
When, however, an adjustment is required, the operator, grasping the wheel-O, pushes the shaft- N rearward, carrying the gear .M to engagement with the idler L, after which he rotates the wheel O, thereby movingthe liner-controlling rack J upward or downward until it hasl pushed the required num? ber of liners into position to be acted upon by the slide I. The wheel O has, vas shown in Figs. 1 and 2, a flange o provided, as shown in Fi l with graduations representing ems, an adapted to be read in connection with the fixed mark or pointer, so that the' o erator, to adjust the mold to ,they require length, .has only to turn the wheel until the ropergraduation alines with the pointer, a er which, the shaft is permitted to slide forward to disengage the gear M. The mold disk stops, in the course of its rotation, in definite positions, as usual, and in order vthat the gear M may becertain to properly rengage the idler L, I provide for locking the gear M against accidental rotation. This is effected by providing its shaft N with-a-second pinion m adapted to engage al lixed locking plate m when the shaft N moves forwar 939,262A j a The matrix line, when in the casting position before the mold, is conlined, as usual in this class of machines, at one end by a horizontally sliding jaw l), which must-be secured at a distance from the opposingjaw equal to the length of the mold and of the slugs produced theiein. For the purpose of locking this jaw in its ditferent positions, l provide a vertically guided plate Q, havshoulders end of the jaw. By raising and4 lowering the plate, it may becaused to lock the jaw in any position, that is to say, for any length of line.
It is usual, after the casting action, to permit a slight backward motion of the jaw in order to release the confined line and permit the wedge-justitiers therein to fallto their normal positions. In order tof permit this movement, I provide the locking plate Q, with a vertical slot y engaging a stud or itsjequivalent g2 on a nut m7,'which receives'` a slight horizontal motion through a pinion m3 on its end, the pinion being in turn actuated by the mechanism of the machine. So
far as this nut and its acti'iating devices are concerned, they are identical with those indlcated by corresponding letters in U. S.
Patent No. 436,531. This nut may be adjusted at will to move the jaw a distance less `than the length of the teeth g. This permits theimold and the jaw to be adjusted to produce slugs of any length required between the regular or standard lengths.
in order .to insure an adjustment of the jaw P corresponding to the adjustment of the mold as to length, l attach tothe jaw a downwardly extending rack-bar R, which engages the pinion 'l' on the mold-adjusting shaft N. I'Vhen, therefore, this shaft is turned to regulate the length of the mold, it sets the plate Q at. such height as to lock the jaw l in the required position. The essence of the invention in this regard consists in a. mechanical connection between the means for determining the position of the jaw and the means for determining the length of the mold, and it will be manifest to the skilled mechanic that 'the parts `#may be widely varied in form and arrangement without departing from my invention.
I lwill now describe the means for adjusting the mold cap to vary the thickness of the slug. The mold cap is urged constantly a way from the body and the liners by under lying springs f, seated in the body "andis support ed and urged toward the body against the influence of the springs by a vertically guided wedge bar f, seated at one side against the cap, and at the opposite side against the mold disk or other solid support. By moving this wedge-bar downward, the cap is crowded inward and the thickness of the mold slot and the slugs reduced accordframe.
ingly. When the wedge is movedl inthe opposite direction, the springs.automatically force the cap outward to increase the width of the slot. The wedge fis notched on one side and locked in its adjusted positions by a spring-actuated pawl The vertical movement of the wedge is effected by an arm .s ou the upper end of a rack-bar S actuated 1 by a pinion s on the end of' a horizontal mg on its upper surface a series of stops or y to engage and support the outer shaft which is provided at its forward extremity with a hand-wheel sa, so that by vturning this wheel, which is suitably graduated for the purpose of determining its ad justment, the mold may be adjusted to pro duce a slug of any thickness required.
As the mold revolves with the disk while the adjusting arm s and-its connections are mounted on the main-frame, provision must be made for throwing the arm into engagement with wedge f when the mold-is to be adjusted, and out again after the adjustment has been effected. To this end the rack-bar S ismounted, as shown in Figs. l and 6, in a-hand-lever T of angular form,
`having at the lower end the horizontal hole t* to receive a supporting axis on the main- By swinging the lever T sidewise about said axis toward and from the edge of the mold disk A, the arm s may be thrown into engagement withv the wedge f.. The lever is also provided at its upper end with one or more teeth t whiehengage the teeth of the disk in order to lock itiirmly against rotation while the adjustmentr of the mold ag is taking place.
While the mold sta-nds in the position shown, with its slot in a vertical position, the slugs are ejected therefrom and driven forwardv between two trimming knives Il, ll, one of which is 'adjustable by means of a vertical wedge u as usual. This wedge f is also operated bythe arm S. In other words, this arm operates simultaneously the wedge for adjusting the thickness of the mold slot and the wedge u for determining the adjustment of the knives. The arm engages and disengages the two wedges in like manner, the two ends of the arm being provided, as shown in Fig. G, vwith horizontal slots 81 and s to receive studs on the sides of the .respective wedges. The knife-adjusting wedge is locked as usual, bya springactuated pin u. Before the wedges can be moved, they must both be unlocked; For this purpose, I mount on the side of the hand-lever T a thumb-lever t connected by a link t2 with the slide t mounted in the side ot' themain lever, and having lateral arms to engage the latch f3 and the pin u.
To eifect the adjustment of the mold and knives, the mainvlever T is moved to engage and lock the mold disk and throw the .arm s into'engagement with the Wedges, after which thejsecondary lever t is actuated to, unlock the wedges, which are then adjusted 1 iio iso
corresponding adjustment of the mold and the knives.
It iste be noted that the liners are advanced, toward and against the cap by Y spring connections, and that they follow the Xia a engage the liners from the plate, and concapv automatically to' any position in which 4 it .may be placed.
v Having thus described my invention, I claim and' desire to secure by Letters Patent Vl.
