LIN'O'IYPE -MA.CHINE Specification 01" Letters Patent.

Fatented June 22, 1909.

Application filed February 15, 1908, Serial No. 6,053. Renewed April 5, 1909. Serial No. 488,069.

To all whom it may concern:

Be it known that I, F RANCIS B. GoNvin-isn,

of borough of Brooklyn, county of Kings,

and State of New York, have invented new and useful Improvement in Linotype-Mm chines, of which the following is a specification.

This invention has reference to that class of line-casting machines, generally known under the trade mark Linotype, in which composed lines of matrices are presented successively to the face of a slotted mold, in order to produce lines of type characters on the edge of type metal slugs cast therein. At the present day, it is a common practice to adapt these machines for the production of two different alphabets by providing each matrix with the same character in two styles or sizes, and so arranging the mechanism that the matrices may be assembled and transferred to the mold at a high or a low level, in order that the upper or the lower characters may cooperate therewith, as desired.

Mechanisms heretofore in use have generally been constructed in such manner that each matrix added to the line in the course of composition may be adjusted to the upper or the lower level as demanded, a double system of horizontal guides being provided to maintain the matrices at their respective levels during their transference to the mold.

My improvement is intended more particularly for use in connection with the machine represented in my application for Letters Patent ofthe United States filed on the 9th day of November, 1907, Serial No. 401,412. In this machine it is not convenient to make use of the matrix-controlling mechanism such as above described, and I therefore provide for setting all the matrices in the first instance on a common level, and thereafter changing the level of the entire composed line in relation to the mold, so as to present the upper or the lower characters thereto, as deman ded. The shifting mechanism is preferably arranged in front of or adjacent to the mold, and combined with automatic mechanism for restoring the line-support to the nor mal level.

In the drawings,-Figure 1 is a vertical cross-section from front to rear through the casting mechanism, with my improvement incorporated therein. Fig. 2' is a similar cross-section on an enlarged scale with the parts in casting position and the matrices alined to cast the upper characters. Fig. 3 is a similar view with the matrices adjusted to cast the lower characters. F 4 is a perspective view from the front with the viseknee and its line-confining jaws removed, showing the delivery endof the assemblage channel, the mold, galley, and adjacent parts. Fig. 5 is a vertical section through one end of the mold and the connected means for advancing the line of-matrices beyond the casting position. Fig. 6 is a hori zont al section through the means for advancing the line beyond the casting gether with the right-hand jaw and adjacent parts. Fig. 7 is a right-hand side elevation of the parts shown in Fig. 4 with the linesupporting and advancing devices shown in vertical cross-section. Fig. Sis a perspective view looking from the rear and showing principally the rear face of the vise-knee, the lineconiining jaws, and adjacent parts,-the lefthand jaw being shown in its forward or inactive position to resist the line as the latter is advanced to the casting position. Fig. 9 is a perspective view of the right-hand vise-jaw looking from the rear. Fig. 10 is a perspective view of one of the two-letter matrices such as are used in the machine. Fig. 1 l is a loi'igitudinal Fig.,12 is a llhorizontal section through the casting. mechanism on the line 12-42,

Fi 11." lhe matrices Y, used in the machine and shown in Fig. 10, are of the same general shape as those used in the well-known Mergenthaler linotype machines, They consist each of a body portion having its upper end notched and provided with distributing teeth 3 its corners provided withlugs 'y, y, g and 3 and one of the vertical edges provided with the intaglio characters or matrices proper 3 and y. y

Matrices representing the characters for one line are assembled or composed into lines (see Fig. .4) with interposed justifiers or spacers Z of the usual type, each consisting of two oppositely tapered wedges. The ine is com'i'osed (see Fig. 4) in an assemblage channel Fbetween two plates f, f ,on which the upper shoulders of the matrices and justiiiers rest. The composed line 18 advanced from the assemblage position toward the left to the casting position by a horizontal pusher including two plates 'n and 12/,

vertical section on the line l1-l1', Fig. 2, looking toward the rear.

5 assemblage channel F terminates at a point did, ointly guide and sustain the composed line ported thereby. The bar f has its upper 20. front of the mold in a position to receive and end of .a Vertical slide 0. When the parts tains the justifiers independently of the level that they may be transferred laterally :5 spring 0 and depressed by a cam 0 It will 0 Figs. 2 and 3, while the matrices ride upon the matrices, as shown in Fig. 8, by a stud i (Fig. 12) projecting from a sliding wedgebar i and engaging the shoulder on the jaw. The wedge-bar is connected by a link 2' with a lever having cam connections, as in my prior application, whereby it is moved forward and backward in order not only to move the "stud 2' but also to crowd the jaw laterally against the matrix line. When the j I is drawn forward to its inoperative position, a latch-pin i (Fig.3?) engages a notch in the lower face of the wedge-bar i and holds the parts in their inoperative positions. As the matrix line is advanced to the casting position, a block 2' (Figs. 7 and 11) on the under side of the line-pushing plate a engages an arm 2'' (Figs. 7, 8 and 11) on a horizontal.rock-shaft i, which carrieson its forward end an. arm 1' (Figs. 7 and 8) which engages the latch-pine, before referred to, in order to effect its disengagement from the wedge-bar i thereby unlocking the bar and the jaw I, so that the latter may be projected rearward across the end of the line of matrices. In brief, the act of ad- 'vancing the matrix line to the casting position causes the advance of the jaw I behind the line to-confine it insuch position.

The two matrix-confining jaws and the justifier-elevator O are mounted in a casting 9, known as the casting-vise knee, and formv guided in grooves in the side plates. This pusher is actuated by a hand-lever and connect10ns, shown'in my original application and foreign to the present invention. The

just to the right of the casting position, but it is continued in effect to the left by the horizontal plate f ,.the fixed bar f, and the 'y'ertically movable j ustifier-elevator O, which lie-casting position. The plate f has its ppe'r edge, in line with the lower rear ears ofthe'matrices, so that as the line is shifted to the left, they ride thereon-and are supat t surface in position to receive and support the forward upper ears of the matrices as the line is advanced at the assembling level.

The justifier-elevator O, which standsin sustain the upper ends of the justifiers Z when they are in the casting position, consistsof two horizontal arms fastened to distance pieces between them, and to the upper are-in the casting position, this elevator sus matrices, and after the casting action, the rise of the'justifier-elevator serves to lift the ustifiers out of the matrix line and to such mg a part of the main-frame. This casting, which is locked rigidly in position by an cecentric shaft 0 provided with a handle 0' (Fig. 1), may be unlocked at will and moved forward to give access to the other parts. hen the line is in the casting position, it stands directly-in front of and in contact with a horizontally slotted mold K, which is momentarily closed at the remand supplied with molten metal by the mouth of the melting-pot M. The mold is movable to and from the matrix line, and the pot is movable to and from the mold, as heretofore.

to their magazine. The elevator 0 receives motion, as shownin Fig. 1, through a link 0, and an elbow-lever'o, which is raised by a be understood that as the line of matrices and spacers is shifted horizontally to the casting position, the ears of the spacers enter the grooves 0 in the elevator O, as shown in the upper edges of the plate f 7 and barf", by which they are sustained in position.

'J is the jaw for confining and supporting the left end-of the matrix line at the casting position. It is in the form of a horizontally sliding block seated-in the justifier-e-levator O, with ribs guided in grooves 0 therein. It stands normally at the right side of the elevator when the latter is down and supports the forward end of the matrix line as the latter is advanced to the left toward the casting position. The movement of this jaw in advance of the line is limited by an adjustable stop 7' (Figs. 11 and 12) which is seated firmly in the elevator and engages a lugy' on the bottom of the jaw.

During the justifying and casting operavtions, the line is confined between the jaw J andthe right-hand jaw I. The jaw 1 con- .sists of a bar having a forward and backward sliding movement across the end of the ma trix line. A spring 2' urges the jaw rearward to its operative position; as shown in Fig. 12. .The jaw is drawn forward and held normally i'in an inactive position beyond the path of and arranged to operate as in my prior application.

Passing now to the parts which form the subject-matter of the present invention, for the purpose of supporting and vertically ad- 1,15, justmg the matrix line, I seat in the viseknee .0 a vertically guided slide t, having in its upper end a horizontal groove t adapted to receive and confine the lower forward ears of the matrices. 'By moving this plate upward and downward, the entire line of matrices may be raised or lowered, so asto present their loweror their upper characters opposite the mold and' in position to form characters on the slugs cast therein. The plate is urged constantly upward by a spring if bearing against the stud thereon. For the purpose of locking the plate down when required, a sliding pin i is seated in the frame in position to enter a hole t 'formed 1n the .130

The foregoing parts may all be constructed drawn slide. The pin'is provided with circumferent al grooves to receive a spring-actuated pin f, by which the pin may be held in either of its two positions. In the normal operation of the machine, the slide is locked down by the pin so that the matrices are received and used in the lower position, or in other words, at the assembling level, so that their up er characters are produced on the slugs. Vhen it is required to produce the lower characters, the pin is withby hand and the slide permitted to raise the entire line of matrices from the lower position shown in Fig. 2, to the upper position shown in Fig. 3. It will be rememered that after the casting operation, the spacers Z are lifted out of the line by the e evator O. It is desirable that the matrices which remain behind, shall be lowered to .their original level, in order that they may be shifted to the left preparatory to their elevation and distribution, as heretofore. To this end, I providethe slide t with a stud t, which projects beneath the vertically movable justifier-bar 2, already referred to. After the. casting action, this bar descends from the position shown in Fig. 3, to that shown in Fig. 2. In so doingyit depresses the stud t and plate t, lowering the entire matrix line at one operation to the original level. The plate remains in this position not onlv during the transfer of tie first matrix line to the left, but also until it re- -ceives the next matrix line from the right. It will be observed, therefore, that it the lower matrix characters are to be used continuously, the pin is withdrawn and permitted to remain in the position shown in Fig. 3, and that the matrix line will be re ceivcd in front of the mold at the lower love and automatically lifted by the plate I. as the latter is released by the rise of the justiiierbar 2*, and the line finally lowered automatically to its original level after the casting action. In other words, the line importing plate t is automatically ra' whenever the lower matrix charz'tcters are being employed. If, on. the other hand, the upper'matrix characters are to be continuously employed, the plate may be locked down and permitted to remain in position.

The upward movement of the plate t is limited by its contact with the under surface of the bar f, as shown. in. Fig. 3.

It is, I believe, wholly new provide means for presentin line of matrices in one castin the mold, and means for 1310?. automatically to'a second castin position prior to the casting action. It is a so wholly new in the art, I believe, to providemeans for guiding the composed line of matrices in a continuous path from the assembling to the casting position, and thence in a continuing course to the elevating position, in combinain the art to a corny. rscd tron be! ed and lowered casting position, is advantageous in that the operator is relieved from the care and labor of watching and shifting the line, and mitted to direct lns attention to the [comp y positively and at the proper time, so that no oversight or carelessness on the part of the operator can prevent the proper sequences of o ierations. r

horizontal shoulders to engage the'lowerrear ears of the matrices when they are in the upper, as well as when they are i n,,the lower, positions,

The justiiicr-ba'r z", and the other parts,- are so shaped and controlled that the slidet is permitted to complete its upward movement before the bar 2 encounters the lower end ofthe justifiers Z. The justifier-bar is actuated, as shown in. Fig. 1, by a link 2 and the elbow-lever 2 urged upward by a spring 2 and forced downward by a came". This cam is provided with a surface 2 which er- Inits the justifier-bar to rise and lift the s ide t the required distance before the justifying actions take place. The-concentric face 2' of this cam, which holds down the justiiicr between the justifying actions, of the same radius as the portions 2' and 2 and conse quently the justi'fier-bar is not drawn down far enough to engage the lug t after the plate has been permitted to rise, until the increas ing face 2 comes into action subsequent to the completion of the casting operation and the unlocking of the line of matrices.
