LINQTYPEl-.MACHINEQ sPnoIFIOATION forming part of Letnersratent No. 732,383,uated fune 3o, 1903. Application filed March 18, 1903. Serial No. 148,415. (Novmodel.)

slugs or line-printing bars are commonlyused. It is frequently desirable to use these machines for producing slugs or forms for the printing of tabular matter, or matter having the figures or characters arranged in columns. When the continuous slugs are cast,`as usual, of the full widthof the table, it is difficult to secure exact alinement of figures in the vertical columns and impossible to insert co1- umn-rules unless vertical slots are sawed ltransversely through the slugs to receive them.

The aim of my invention is to provide simple meansrwhereby the ordinary machines may be adapted to produce, instead of the ordinary continuous slugs at one operation, a series, of short slugs to be used end to end. In this manner I am enabled to bring the figures or characters on each slug in alinement vertically with the slug above and below it. I am also enabled to introduce into a form composed of .these lines of short slugs columnrules in the same manner that they would be inserted in an ordinary type-form. I accomplish the desired result by inserting in the ordinary slotted mold adjustable partitions, whereby it is divided into a series of short lengths or sections adapted to form a'correspending series of short slugs of lengths corresponding to the widths of the columns to appear in the table. In connection with this mold I employ specialy division-pieces, abutments, or quads, adapted to interlock with the partitions ofv the mold, so that they are kept in exact alinement therewith and of exactly the predetermined distances apart. The division-pieces thus secured against lateral movement determine the position of the intervening matrices and locate the figures on the face of the slug in exact positions re- 5o quired. The fixed division-pieces or quads divide the matrices in the line into groups of definite Width, each group representing the width of one column. When the figure-matrices are made of uniform Width or in width multiples of acommon unit, they will justify to produce a compact line. When, however, matrices of different widths are used, so that ploy in the line adjacent to each of the mat- .rices an ordinary expansible Wedge spacer ing sections, which will act one on each of the spacers.

Referring to the drawings, Figure l is an inside face view of the vise or line-supportingl mechanism of a linotype-machine containing a lineof matrices and spacers in connection with myimproved parts. Fig. 2 is aperspectrve `View of the mold, showing the abutments or division-pieces therein and one of thel interlocking matrices. Fig. 3 is a side view of one of the abutments or division-pieces. Fig-4 is a perspective view of one of the mold-partitions. Fig. 5 is a side elevation showing the mold, the galley to receive the slugs, and the means for delivering the slugs from the mold to the galley. Fig. 6 is a horizontal section on the line 6 6 of Fig. 5. the parts shownin the two preceding gures. Fig. 8 isa front or edge view of the series of slugs, such as arevproduced inthe mold at one'operation.

Referring to the drawings, A represents the vise-frame, forming a portion of the main frame; B and C, the two opposing jaws in the top of this frame for the purpose of confining the matrix-line endwise in the casting position and determining its length.

D D represent .ordinary figure or character matrices composed in the line.

E E represent my division-pieces or abutments seated in the line and dividing the same into groups of four, five, or six, more or less, according to the number of vertical rows to appear in each column. These divi- Fig. 7 is Aa front view of the line needs justification, I propose to em- ICO sion-pieces E are of the same external form as the ordinary character-matrices except that they are each provided with a protruding pin or stud e, as shown in Fig. 3. They may be carried in the magazine and inserted in the line during its assemblage by the ordinary key mechanism or they may be inserted by hand.

F represents the slotted mold in which the slug is cast, its face being held during the casting operation tightly against the matrixline that it may be closed thereby as usual. The mold-slot extends through it, as usual, from the front to the back, and in the cap of the mold there are a series of transverse grooves f.

I divide the mold by partition or division pieces G into a series of short lengths or sections corresponding in width to the group, or'

sections in the matrix-line, so that when the mold is filled with molten metal it will produce, instead of the usual solid 'or continuous slug, a series of short slugs. Vhen the mold is in position, each partition G will register exactly with one of the division-pieces E in the line.

Cavities are formed in the front ends of the partitions to receive the studs e of the division-pieces. Owing to this interlocking of the division-pieces E with the mold, the division-pieces are prevented from shifting laterally and are held exactly in the predetermined positions, so that they in turn tix exactly the positions ot` the intermediate matrices D. It follows, therefore, that the series of short slugs cast at each operation will be precisely of the same length as those cast at the next operation and that the figures or other characters formed on one slug will exactly aline vertically with the slugs occurring above or below it in the form.

While I prefer to secure the partitions by forming them, as shown, with ribs seated in corresponding grooves in the mold-cap, it is obvious that they may be varied in form and secured against lateral movement in any appropriate manner.

I propose to provide the mold with grooves f at short intervals, so that the partitions may be adjusted laterally and arranged at any desired distance apart to suit the requirements of different tables, and of course the partitions may be made to extend to any desired distance on either side of their ribs, so that there will be more or less space between one partition and the next, as occasion may require.

While I propose to employ the conical projections on the division-pieces to enter corresponding cavities in the partitions, it is manifest that the interlocking surfaces of these two parts may be varied at will, provided only the partitions serve to hold the matrices securely against lateral movement.

For the purpose of delivering the series of slugs or linotypes from the mold after it has been turned to the usual discharging position I employ, as shown in Fig. 5, ejectorslide II, having a series of narrow ejectorblades h,corresponding substantially in width to the several chambers or sections of the mold. In order to support the series of slugs and hold them in line as they are delivered into the galley K in front of the mold, I provide a forwardly-yielding plate L, which stands normally opposite the usual vibrating pusher M, which latter acts to push the slugs laterally into the galley. When the ejector advances, the series of short slugs are delivered between the plate L and the pusher M, whereby they are maintained in position one above another and prevented from falling into a pile, as they would otherwise be liable to do. -The plate L is mounted on a pivot Z, so that it may swing forward away from the slugs and out of their path when they are to be pushed laterally in the galley. A spring Z2 tends to hold the plate L in its operative position. As the pusher M advances toward the matrix-line a beveled lip m on its lower portion acts with a lifting effect beneath a lip lon the plate L, near its pivot, the effect being to swing the plate L forward beyond the slugs and out of the path of the pusher.

It will be observed that the partitions G are inserted from the front of the mold, so that they are held back to their places therein by the pressure of the division-pieces or abutments E against their forward ends. It will also be observed that the ribs of this partition terminate at a distance from the rear end, so that being seated in corresponding grooves it is impossible to push the partitions backward out of position.

In making use of my invention the operator iirst determines the widths of the several columns which are to appear in the table. He then inserts the partition-plates G into the mold in the required positions to produce short slugs of the requisite length.

In assembling the line of matrices the special division-pieces or abutments are inserted at distances apart corresponding tothose between the mold-partitions. The machine is then operatedin the ordinary manner. When the matrix-line is presented to the mold, the studs of the division-pieces interlock with the partitions in the mold. If the line is not already justified, the expansible spacers N, which are inserted adjacent to the divisionpieces, are thrust upward, each being subjected to pressure independently of the others, whereby small groups of matrices are justified independently and in one direction between the division-plates or abutments. The ejector acting in due time drives the entire series of slugs out of the mold and alongside of the plate L. This plate is in due time retracted, the line pushed forward horizontally in the galley by the follower M, and the plate L returned to its operative position to maintain the vertical alinement of the se- IOD IOS
