LINER FOR LINOTYPE-MACHINES.

Specification of Letters Patent.

Patented J an. 5, 1909.

Application filed August 2%, 1908. Serial No. 450,068.

To all whom it may concern:

Be it known that I, MATHIAS S. MILLER, citizen of the United States, residing at Lawrenceburg, in the county of Dearborn and State of Indiana, have invented certain new and useful Improvements in Liners for Linotype-Machines, of which the following is a specification.

This invention relates to liners for linotype machines, and has for its object to provide improved means for varying the molds which are used in linotype machines to form the printing bars or slugs, the object being to provide means whereby the size of the mold may be varied in length or width in a convenient and exact manner.

Heretofore the length or width of the mold slot has been changed by removing a single piece liner and substituting another of different length or width. This practice required a large number of liners in order to meet the various requirements of the practical art.

My invention comprises a three piece liner consisting of a middle piece and end pieces. A sufficient stock of end pieces of different thicknesses will be provided and a suflicient stock of middle pieces of different lengths, the middle piece being made as thin as the smallest type cast and capable of being used with all thicknesses by the casting of lead around the same at the time the first line is cast. By this means, sixty pieces will give as many adjustments as three hundred would under the old practice. The middle pieces have definite lengths, and conse quently no manual adjustment of the length is necessary, but the length of the liner will be the same for all thicknesses, and after changing new lines will be the same length. That is, when a change is made from one length to a second, and then back to the first, the last will match exactly with the first with respect to length, and the same is true with respect to thickness.

The invention is illustrated in the accompanying drawings in which- Figure 1 is a plan of the under side of the liner assembled, without the lead filling, however; Fig. 2 is a plan View of the parts separated; Fig. 3 is a plan view corresponding to Fig. 1, with the lead in place; Fig. 4 is a section on the line 44 of Fi 3. Fig. 5 is a front view of a linotype mo d having my invention applied thereto; Fig. 6 is a view showing sets of pairs of end sections.

Referring specifically to the drawings, 1

and 2 indicate the two end sections of the liner. A number of these sections are provided corresponding to the number of different thicknesses of type cast. All of the sections N o. 1 and No. 2, respectively, are made the same width (measured laterally or from right to left as in use). The middle sections 3 are made in different lengths according to the lengths of line desired, a long liner producing a short slug, and vice versa. All of the sections 3 are made the same thickness, this thickness being that of the smallest type cast, but any one of the sections 3 is capable of being used with all thicknesses or sizes of type, the remaining space being filled up by lead injected around the part 3 at the time the first line is cast, as indicated at 6. Section 1 is provided with a key 4 which fits in the usual groove in the bottom of the mold, so that the section 1 always occupies the same position. The position of the section 2 varies according to the length of the section 3 selected. To make a long liner, a long middle section is used, and by having a set of middle sections, liners of any length may be made. The stock of pieces 1 and 2 therefore corresponds in number to the thickness of the various sizes of type cast, and the stock of the middle pieces number 1 corresponds to the various lengths of line to be made.

Each of the sections 1 and 2 has a dovetailed mortise in which the flared ends 5 of the sections 3 fit snugly.

In assembling a liner of any desired length and width, the parts 1 and 2 are selected according to the desired thickness, and the section 3 is selected according to the desired length, and the parts are fitted together, the dove-tailing holding them perfectly true. T he liner thus assembledis placed in one end of the mold cavity as shown in Fig. 5 with the part 3, and likewise the parts 1 and 2, resting upon the bottom of the mold slot. If the parts 1 and 2 are thicker than the part 3, the space on top and along the edges will, when the first line is cast, be filled with lead, which will thus form a solid liner of the desired length. To separate the parts after the liner is removed, the lead is broken off. To make a liner of a different length, the part 3 is removed and another similar part of the selectedv length is put in its place, the end piece 2 being moved along to pro er position. Since the parts 3 are of stan ard length, the change from one length to another will always bring the liner to the exact adjustment, without any possibility of error. Since the part 3 is as thin as the smallest type, it can be used for that size and also for any larger size, because the lead will fill in to any desired thickness. 'lhe change from one length to another can be quickly made, as well as the change from one thickness to another, and the large number of liners varying in length and thickness, as now used, is avoided. 'lhus at present with, for instance, ten sizes of type and thirty lengths of line, three hundred difierent liners are needed, whereas with the present invention, ten each of the pieces 1 and 2 and thirty of the pieces 3 are all that is needed.

No limitation is implied by reason of the particular form shown, but various modifications may be made within the scope of the invention as defined in the following claims.

I claim:

1. A liner for linotype machines, comprising two end sections, and an intermediate section attachable at its opposite ends to the respective end sections.

2. A set of liners for linotype machines, comprising end sections of various thicknesses, and intermediate sections of various lengths attachable at their opposite ends to respective end sections.

3. A liner for linotype machines, comprising two end sections, and a separate intermediate section fitting between the end sections to space the same apart, the intermediate section being removable to permit the substitution of other intermediate sec tions of different lengths.

4. A liner for linotype machines, com prising two end sections, and an intermediate section fitting between the end sections and having means to engage and hold the same.

5. A liner for linotype machines, comprising two end sections, and an intermediate section detachably connected at its opposite ends thereto, the intermediate section being of a thickness difi'erent from the end sections, and not greater than the smallest size of type to be cast.

6. A set of liners for linotype machines, comprising sets of pairs of end sections of various thicknesses, and an intermediate section attachable at its opposite ends to the respective end sections of any of said Ipairs.

7. A set of liners for linotype mac ines, comprising sets of end sections of various thicknesses and intermediate sections of various lengths attachable at their opposite .ends to the respective end sections.

In testimony whereof, I aflix my signature in presence of two witnesses.
