LUTHER L. KENNEDY, OF BROOKLYN, NEW YORK, ASSIGNOR TO MERGEN THALER LIN OTYPE COMPANY, A CORPORATION OF NEW YORK.

LlNOTYPE-MACHINE.

Patented Dec. 12, 1905.

To all whom, it may concern-.-

Be it known that I, LUTHER L. KENNEDY, of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Lino type-Machines, of which the following is a specification.

The aim of my invention is to adapt the molds of the Mergenthaler linotype shown in Letters Patent N 0. 557,000 and of kindred machines to produce at will solidfiat slugs or linotypes of uniform thickness or linotypes recessed in one side, as shown in Letters Patent of the United States N 0. 665,326 to Isaiah Hall.

To this end the invention consists in a liner or core of peculiar form adapted to be inserted and secured within the ordinary linotype-molds and in the combination of such liner with the mold.

While the liner may be modified in detail to adapt it for application to linotype-molds of the various forms in use, I prefer to employ it in connection with the so-called universallyadjustable mold represented in Letters Patent of the United States to J. R. Rogers, No. 620,804, and in the accompanying drawings I have illustrated such application. A Rogers mold provided with an improved liner forms a convertible or changeable mold which may be used to cast either solid slugs or recessed slugs at will.

Figure 1 is a front view of a linotype-mold having my liner applied therein. Fig. 2 is a rear elevation of the same. Figs. 3, 4, and 5 are cross-sections on correspondingly-numbered lines of Figs. 1 and 2. Fig. 6 is a perspective view of the liner. Fig. 7 is a per spective view of one of the slugs or linotypes. Fig. 8 is a perspective view of a modified form of liner.

Referring to the drawings, A represents the body portion of the mold presenting a fiat upper surface; B, the cap portion overlying the body and presenting an under surface parallel with the top surface of the body.

0 and O are two liners or spacing-pieces seated between the cap and body at opposite ends for the double purpose ofseparating them a distance equal to the thickness of the required slug and of determining the length of the slug. In other words, termine the dimensions of the slot or mold proper in which the linotype is cast as usual.

When the cap is seated directly on the these liners de-' I liners and the parts secured by the usual confining devices, the mold will produce a slug or linotype of rectangular outline and practically uniform thickness throughout. It is frequently desirable, however, to form the linotypes, particularly those for very large type-faces and for very long lines, with cavities or recesses in the side face, as shown in Fig. 7, and this for the double purpose of re ducing the amount of metal and the weight and of reducing the amount of air to be displaced from the mold as the metal enters, so that a more solid type-face may be obtained. To this end I provide a core or liner D, such as shown in Fig. 6, consisting of a plate of metal adapted to be seated snugly under the mold-cap with its ends extended and con fined between the cap and liners O C, so that the underside of the core forms for the time being the top of the mold cell or slot. The under side of the core is formed with downwardlyextending projections or bosses d to form the cavities or recesses in the side face of the slug. It will be observed that these bosses extend to the rear face of the mold, but that they terminate in the rear of the frontface, so that the front edge of the slug bearing the type characters is cast of full thickness. It will also be noticed that the bosses of the core are separated by transverse grooves d, which form on the slug corresponding ribs -0Z standing out flush with the front edge of the slug to give the type-face the requisite support and to bear against the adjacent slug in the form.

The ends of the core are preferably notched, as shown at (1 in order that they may embrace and be kept in place by the usual end bars or gibs which connect the cap and body.

The length of the slug produced in the mold is varied by substituting for the liner 0 a similar liner of different length, and the thickness of the-slug is varied by changing both end liners.

When the length of the slug is to be changed, the core D and the liner C will be replaced by others of suitable length, or the liner O may'be recessed, as illustrated in Fig. 8, to correspond with the sectional form of the core, so that the one core may be used with liners of different lengths, the end of the piore overlapping the recessed surface of the nor.

If desired, the liner may be connected to the cap at one or more points between its ends in order to prevent it from springing away therefrom. This may be accomplished by means of a screw, inserted as shown in dotted lines in Figs. 1 and 2, by providing the liner with a longitudinal rib on the upper surface to enter a corresponding groove in the cap or by any equivalent means.

While the ribs (1 are advantageous in assisting to support the type-face of the slug and in sustaining the slugs against the compression to which they are subjected when the liners are locked together in the form, it is to be understood that they are not necessary in all cases and that in the case of short slugs, such as those employed in newspapers, a single cavity in the side, extending nearly the entire len th of the slug, may be used in the absence 0 any dividing-ribs.

Heretofore molds for casting recessed slugs have been limted to that use alone and were incapable of casting solid or fiat slugs. By means, of my removable liner, which may be cheaply constructed, I am enabled to quickly convert or adjust an ordinary mold so that it will produce slugs of either form, as demanded.

What I claim as my invention is 1. In combination with a longitudinallydivided slotted linotype-mold a removable core extending the entire len th of the moldslot and having its ends con ed by and between the mold members.

2. A slotted linotype-mold, having a movable cap, in combination with an internal detachable core confined in place by the cap and having projections to form cavities in the linotype.

'3. As a new article of manufacture, in a linotype-mold, the combination of the body portion, the cap portion, intermediate liners at the ends, and a removable core, having its extremities confined between the cap and the liners, and having its body portion provided with projections to form cavities in the side of the linotype, said projections terminated at a distance from the front of the liner, whereby the mold is adapted to form the type-bearing edge of the linotype of full thickness.

4. As a new article of manufacture, a core for linotype-molds having one or more projections on its side face to form recesses or cavities in the side of the slug, and having its ends extended beyond the operative portions and fashioned substantially as described for confinement by and between the two portions of the mold substantially as described.

5. In a linotype-mold, the combination of cap. and body portions, the intermediate liners, and the core having projections on its under surface, one of the liners being recessed to admit the projections on the core, substantially as described.

In testimony whereof I hereunto set my hand, this 16th day of March, 1904, in the presence of two attesting witnesses.

LUTHER L. KENNEDY.
