To (ZZZ whom, it may concern;

Be it known that I, LEWIS WARD, a resi.

dent of Wichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Adjustable Liners for Linotype-Machines; and I do here-' by declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvementin" adjustable slotted molds such as are used in linotype-machines to form the linotype-slugs or line-printing bars, the object being to perhalt the adjustment of the mold in order to vary the size of its slot and of the slugs cast therein in a cheaper and more simple manner than heretofore practiced.

As shown, for example, in Letters Patent of the United States No. 620,80 linotype molds consist of a body portion, an overlying cap, and two intermediate liners or spacingpieces, which determine both the length and.-

the width of the slot.

Heretofore it has been the usual practice to effect a change in the length of the mold slot by removing the liner at one end and substituting another of diilerent length. When a change in the width of the slot was required, both liners were removed and replaced by others of a thickness corresponding to that of the required slug. This practice necessitated the employment of a large number of expensive liners in order to meet. the various requirements of the printer. To overcome this diiliculty, I make use of composite liners, adjustable in length and also adjustable in thickness, so that a single liner will serve to adjust the mold-slot at on e i nd both as to length and width.

The details of construction may be variously modified without departing from the limits of my invention.

In the accompanying drawings 1 have represented a construction which in practice has given good results.

Figure 1 represents a front elevation of a linotype-mold having my improved liner therein. Fig. 2 is a perspective view of a mold, showing the members of the mold and liner separated. Figs. 3, 4., and 5 are pers ectiveviews showing the various parts of t e liner.

Referring to the drawings, 1 represents the.

body or baseportion of the mold 2, the overlying adjustable cap, and 3 a. liner located be.-

tween the capand body, with a transverse I rib fitting into the latter and serving to determine the distance between them and also to form one, end of the mold slot or cell 15, i which the slug or linotype is cast.

The foregoing. parts are of ordinary construction. The cap and bodyniust be sepa rated by liners at both ends. Heretofore it has been customary to employ at solid liner similar to the liner 3. using a second solid liner I provide a composite liner, consisting of the principal mamers a and b andone or more supplemental members lb. The parts a and b constitute the main portion of the liner and are to beused without the supplemental members for casting thin slugs. The part a 1s constructed with a transverse rib 5, seated in a corresponding recess in the body of the mold for the purpose of holding it against longitudinal movement and of lieepmg it properly in line.

the lefta Instead of.

The outer or thicker end of this liner is of the same thickness as the liner 3 and determines the distance between the mold-cap and body. The inner end 6 of the member a is reduced in width and in thickness, so that it forms along horizontal tongue. The member I) has its inner end and longitudinal edges of the same thickness as the outer end of the member aand is formed in its upper face with a longitudinal groove adapted to receive the tongue 6 of themcmber a, and also provided with a series of holes or notches 9, to receive a stud 8 on the tongue. When the tongue of the m ember (t is seated in the groove of the in ember b, the two constitute jointly a liner of variable length, which maybe seated between the cap and. the mold and the inner end of which will form one end of the mold slot or cell, as shown in Figs. 1 and 2.

"When the length oi the slot is to be increased or diminished, the liner is removed edgewise from the mold, or released by lifting the mold-cap, and the member b moved forward or backward in relation to the member {1. until the distance between the inner ends oi the two liners equals the length of the required slug. The holes 9. are commonly.

me or standard. As regards the liner of variable length, it is only necessary that its members should be'made in such form and connected in suchmanner that the inner end should be movable forward and backward at will to/vary the length of the mold-slot. It

Will be seen that the member 0 serves not only to aidin. supporting the cap and determin-- 'ing the width-0f the mold-slot, but also to uide the movable member b and prevent'it roin moving either endwise or edgewise out -of 'theiequil'ed position.

When it is required to change the'vertical width of the mold-slot'in order to produce slugs ofianother thickness, I use one or more of the supplemental plates or liners 10, seating the same on top of the members a and b, its-shown in the drawings. This supplemental plate is'provided with studs 1], adapted to enter corresponding holes in the member 7), whereby it is kept in proper osition without changing its length, the liner 3 is rethereon; The inner or operative en s of the members b and H) are of like form and stand in line, so that they jointly form the end of the mold slot or cell. There may be any de sired number of the dates 10, of the same or of" different thickness, and they may be placed one upon another.

When the adjustable liner is varied in thickness, as described, which maybedone moved and another of a thickness corre- .sponding to that of the composite liner inl serted. Instead of replacing the liner 3 by another of different thickness the supplemeneeasae tal plates 10 of suitable'form, may be'used thereon to increase its thickness, as in the case of the composite liner. c

When the liner is extended, as shown in Fig. 2, a space is left between the outer end of'the member I) and the thick end of the por-.
