Specification of Letters Patent.

Patented Nov. 20, 1906.

Application filed June 25,1906. Serial No. 323,258.

To all whom it may concern,.-

Be it known that I, PHILIP T. DODGE, of the borough of Brooklyn, county of Kings,

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

My invention has reference to linotypemachines, such as shown in United States Letters Patent No. 436,532, and analogous machines wherein matrices representing the characters to appear in one line of print are assembled or composed in the proper order and the line presented in front of the mold in order to formthe type characters on the edge of a slug or linotype cast therein.

In practice the mold is adjusted to produce slugs of uniform length; but in setting advertising matter, headings, and the like the type-line, frequently shorter than the must be centrally located thereon. Heretofore this has been accomplished by filling the line to the right and left of the matrices containing type characters with quads or blank matrices-an operation involving considerable skill and a substantial loss of time.

' My invention is designed to overcome the loss of time; and to this end it consists,

broadly, in automatic means acting to locate the matrix-line, regardless of its length, centrally in relation to the mold and also to cover and close the ends of the mold extending beyond the matrix-line.

The invention is capable of embodiment in many forms. Any mechanism which will automatically advance the two matrix-coniining jaws having a wide range of movement to points equallydistant from a central line will answer the purpose in view In the drawings I have represented my improvement in connection withy the mechanism shown in United States patent to J. R. Rogers, No. 786,155, Vfonadvancing the righthand jaw when the ,line is to b e quadded fout at one end only.

I am aware that means have been provided l i -for manually changing the distance between *the jaws and for manually changing the operative position of either jaw at will; but

these4 mechanisms are not to be confused the preceding figures, the

with my structure adapted to receive and automatically center matrix-lines of different lengths. The drawings show only those parts which are immediately associated with my invention. The remaining pfiirts may be of the ordinary or any other suitable construction.

Figure l is a rear face view ofthe so-called vise mechanism of the Mergenthaler machine having my improvements incorporated therein, the parts being adjusted to center a matrix-line of any length which may be pre.

sented. Fig. 18L is a similar view of the mechanism adjusted to produce a short line of characters on one end of the slug and automatically quadded out the remainder of the line. Fig. 2 is a vertical central section from front to rear on the line 2 2,l Fig: 1. Fig. 3 is a similar section on the line 3 3, Fig. l. Fig. 4 is a planview of the parts shown in mold and the adj acent mouth of the melting-pot being shown in horizontal section. Figs. 5 and 6 are perspective views showing the product of the machine with the parts adjusted as in Figs. 1 and la, respectively.

Referring that portion of the stationary main frame which gives support to the matrix-clamping devices and which is commonly known as the vise-frame.

H and I are two opposed jaws mounted to slide in a horizontal guideway in the vise-A frame for the purpose of coniining thematriX- line between them while it is inthe casting position in front of the mold. Z represents the matrices representing individual characters and assembled in lme in the order in which the characters are to appear inprint.

K represents the wedge spacers or justiiers' seated in the line between the matrices for the purpose of elongating or justifying the line to the predetermined length when' :lines of maximum length are to be produced.

In castingheadings, advertisements, '&c.,

to the drawings, A represents the usual blank matrices or spaces may be used i'n place of the wedge-spacers. The

matrices are lowered to their position bev tween the jaws H and I and are suspended in the casting positin by the usual verticallyf movable support G, known as the first elevator. The transfer of the matrix-line to this elevator preparatory' to the lowering of the line is effected, as usual, by a horizontallymovable transfer-carriage having two depending fingers e2 e3, between which the line is held While being moved horizontally into the elevator, all in a manner well understood by those skilled in the art and described in the patents above referred to, particularly Patents Nos. 436,532 and 786,155.

In the operation of the machine as ordinarily constructed the line-confining jaws H and I are always separated a distance equal to the length of the mold and the slug to be produced therein, and if the matrices representing the characters form a line shorter than the mold the line is filled out by the use of blank matrices or quads added during the composition of the line.

In the Rogers structure before referred to and shown in the Patent No. 786,155 the line-carrying finger e2 acts on a projection on the jaw I and advances the latter toward the jaw H, standing at one end ofv the mold, until arrested by the intervening matrix-line. If therefore a matrix-line is shorter than the mold, it is confined by the advance of the jaw I, which at the same time covers and closes the end of the mold which is not covered by matrices, so that a smooth or blank surface is formed on one end of the slug beyond the type characters.

In the present embodiment of my invention I have retained this organization, and I utilize the advance of the jaw I to eHect an equal advance of the opposing jaw H. To this end I pivot to the vise-frame an angular lever L, the upper end of which is connected through the link M with the jaw I, while its lower end acts through intermediate parts on a second angular lever L', pivoted to the viseframe and connected at its upper end by alink M or otherwise with the jaw H. The two levers may be connected in any suitable manner. In the arrangement shown the lever L bears on a collar g, which in turn bears on the end of the lever L'. The collar g is formed on a verticallyuided rod Q, which also carries a second col ar g', acting beneath the lever L', `as shown in Fig. 1.

A spring R, bearing beneath a third collar on the rod Q, tends to lift the rod and, through the intermediate levers, to effect the separation of the aws.

The parts operate as follows: The fingers e2 and e3, advancing in the direction indicated by the large arrow, present the matrixline in position to be lowered between the tvro jaws, and at the same time the finger e2, advancing the jaw I through the levers Land L', causes a corresponding advance of the opposed jaW H. In this manner the two jaws are advanced equally in opposite directions toward ,the central line, confining the matrixline, whatever its length, between them, so'

that it is located centrally in relation to the mold.

It will be observed that each jaw has a Wide and unrestricted range of movement and that the line of matrices determines the operative distance between the aws, so that the machine will automatically adjust a line of any length without special regulation of the arts.

T 1e ends of the mold projecting beyond the matrix-line are covered and closed at the front by the respective jaws, which produce smooth surfaces thereon, so that the slug or linotype produced will appear as shown in Fig. 5, with the type characters at the center and blank spaces at the two ends.

When it 1s required. to have a short line of type characters appear at one end of the slug with a blank surface for the remainder of its length, it is only necessary to throw out of action the lever L', so that the jaw H n'lay remain at rest at its outermost position at one end of the mold. The advancing jaw I will carry the matrix-line over against the jaw H and will also close that portion of the mold which extends beyond the matrices in essentially the same manner as in the Rogers mechanism.

In order to prevent the lever L from` actuating the lever L', the collar q is cut away on one side of the center, so that by rotating the rod Q, which is provided with a handle V for the purpose, as shown in Fig. 2, the collar may be thrown out of the path of the lever L.

For the purpose of locking the jaws in position during the casting action, so that the matrix-line may be confined to the roper length, and to resist the expanding in uence of the wedges K when they are used I provide each jaw on the upper side with a series of ratchet-teeth and mount in the frame pawls h5 and i5 to engage the respective jaws.

In the ordinary operation of the machine it is necessary that the matrix-line shall be slightly relieved from end pressure during justification and also after the casting action preparatory to its being lifted for distribution. To this end the pawls h5 are pivoted to a lever U, having its upper end pivoted to the vise-frame and its lower end acted upon by a block P, receiving motion from a verticallymovable wedge W, which will be actuated by the usual cam mechanism of the machine in the same manner that a similar wedge is now operated to adjust the left-hand jaw of the commercial linotype.

The awls i5, holding the jaw I, are connected y a slot and pin i9 with a lever fil, acted upon by a lifting-spring is and by a depressing-finger on the end of the elevator G. When the elevator descends with the matrix-line it depresses the lever i', and the pawls are permitted to engage the jaw. When IOO IIO

the elevator rises the spring is lifts the pawls out of engagement, leaving the jaw free to retreat. The pawls h5 are. controlled by a similar mechanism, being connected to a slot and pin h" with a lever k7, acted upon by a depressing-ringer on'the elevator G and by a lifting-spring hs. The lost motion between thepawls'h5 and i5 and their controlling-levers permits the pawls to ride over the teeth of which they are automatically and equally advanced in order to centrally locate the matriX-line regardless of its length and of the length of the mold, and while I prefer to use connections essentially such as herein shown and while one jaw in advancing effects the corresponding movement of the other jaw it will be understood by a skilled mechanic that the invention embraces any mechanism by which the two jaws .may be automatically and equally moved in' opposite directions, and it will be perceived that this mechanism may be made in a great variety oi forms without departing from the general mode of action herein described.

Having described myl invention, what I claim is- 1. In a linotype-machine, the combination' of amold, two vopposed jaws to confine the matrix-line, and means for automatically advancing the jaws toward'a central point until arrested by the intervening matrices, whereby the line may be centered in relation to the mold.

2. In a linotype-machine containing circulating matrices, the combination of a mold, means controlled by thematrices for automatically centering the matrix-line regardless oi the length of the mold, and for closing the front of the mold beyond the matrices.

v 3. In a linotype-machine, the combination oi two opposed InatriX-coniining jaws, means for advancing one of said jaws toward the v line, and means operated by said jaw to advance the second jaw in the opposite direction.

- 4. In a linotype-machine, the combination of two opposed movable jaws, and, intermediate connecting-levers, whereby the jaws are caused to move in opposite directions.

5. In a linotype-machine, opposed movable jaws to conne the matrices, means vfor advancing the two jaws simultaneously against the matrix-line regardless of its length, and their operative positions.

6. In a linotype-machine, the two reciprocating jaws, means for automatically advancing the jaws to centrally confine the matrix-line regardless of its length, and means for locking the jaws in the casting position.

7. In a linotype-machine, two opposed matrix-confining jaws, means for automatically retracting the two jaws to the maximum distance, means for automatically advancing the two jaws until arrested by the intervening matrix-line without regard to its length, and means for locking the jaws in the inner position.

8. In a linotype-machine and in combination, two opposed movable matriX-connin jaws, mechanism for equally advancing an retracting the two jaws, said mechanism including means for releasing one jaw and permitting it to remain at rest.

9. In a linotype-machine and in combination with a matriX-conining and mold-closing jaw', means for advancing said jaw over the mold and against the matrix-line, and adjustable mechanism whereby the second jaw may be caused to advance in opposition to the first, or permitted to remain at rest.

10. In a linotype-machine, two opposed matrix-confining jaws, means for separating means Jfor locking the jaws in` the jaws to the maximum distance prior to the introduction of the matrices them, and thereafter advancing said jaws until arrested by the intervening matrices.

11. In a linotype-machine, a slotted mold, opposed jaws arranged to advance. over and close the opposite ends of the mold and'to confine the matrices between them, in combination with mechanism for automatically separating the jaws to admit the longest line, .and thereafter automatically advancing the jaws until arrested by the intervening matrices.

In testimony whereof I hereunto set my hand,this 23d day of June, 1906, in the presence of two attesting witnesses.
