Application filed March 10, 1904. Serial No. 197,507.

(No mode;

To (LZ/ whom it may concern Be it known that I, PHILIP T. DODGE, of Washington, District of Columbia, have invented a new and useful Improvement in Linotype-lVIaehines, of which the following is a specification.

My invention has reference to the Morgenthalerlinotype and kindred machines, wherein a printing-slug or linotype is castin aslotted mold against a line of matrices temporarily closing the face of the same, the typemetal being delivered into thc'mold at the rear from the perforated'or slotted mouth of the melting-pot, which acts directly against and serves to close the mold.

The object of my invention is to reduce the weight of the linotypes and the amount of metal contained therein by forming cavities in the base thereof; and to this end itconsists in providing the mouth or throat of the pot through which the molten metal is delivered with one or more studs or projections adapted to enter the mold and serve the ofiice of cores therein, the studs being of such form that they may be withdrawn from the mold and from the slug without disturbing the latter. These studs or cores may be of any sectional form and of any suitable length, provided only they are adapted to be readily withdra n from the mold and the slug therein. "he openings for the admission of metal may be through, between, or in one side of the cores, as preferred.

1n the accompanying drawings, Figure 1 mold of a linotype-machine with the matrices and my improved pot-mouth in operative relation thereto. Figs. 2and 3 are respectively a face view and a cross-section of a mouth piece in accordance with my invention. Fig.

4 is a view illustrating the same in an alter-' native or equivalent form. Figs. 5 and 6 are perspective views illustrating linotypes produced by my improved mechanism.

Referring to Figs. 1, 2, and 3, A represents a slotted mold wherein the linotype B is cast. This mold may be of any ordinary or suitable form and construction.

C represents the matrices alined tempora- I rily against the face of the mold in order that their cavities or matrices proper may form the correspondingcharacters in relief on the edge of the linotype.

D- represents the delivery mouth or throat through which the molten metal is delivered into the mold from a source of supply. This delivery-throat may be integral with the pot, as in the ordinary Mcrgenthaler machine, or it may be independently movable, as in other machines, the only requirement being that it shall connect with a supply of molten metal and means for delivering the same under suitable pressure into the mold.

The mold and the delivery-mouth will be movable one in relation to the other, as usual in this class of machines, so that the mouth may be seated against'the base of the mold to close the same during the casting operation and the parts there-after separated to permit the ejection of the linotype. Up to this point the parts may be constructed and arranged tooperate in the ordinary manner.

In carrying my invention into effect I form on or apply to the mouth D in any suitable manner one or more projections or cores E, adapted to extend into the mold from the rear without closing or filling the same, so that when the linotype is cast these cores will produce cavities of like form in its base. They may be varied in length and in sectional form at will, provided only they leave at the base of the slug a suiiicient body of metal to give it the requisite stability when in use. i

In the form shown in Figs. 1, 2, and 3 the mouthpiece, adapted to produce a slug such as shown in Fig. 5, is of a dovetail form in cross-section and is driven endwise tightly into a corresponding groove in the pot-mouth, as is usual in linotype-machines. or studs shown in Figs-1, 2, and 3 are separated from each other lengthwise of the mouthpiece in order that the sing or linotype may be solid from one side to the other be-- tween the cavities, as shown in Fig. 5.

The holes F, through which themolten metal is delivered, may be located between the cores or projections or extended through the melting-pot or other' The cores 2 be readily removed.

. slug and that the cores, or both. The cores may be locatedso as to lie either at the top or the bottom of" the mold cavity' in order to produce in the slug open cavities 1n one side or face, as shown 5 in Fig. 6.

It will be understood by the skilled .me-

chanic that the studs may be made integral with the mouthpiece or separately formed and As it is a common practice to use a mouthpiece secured thereto in any suitable manner.

of maximum length in connection with a mold which is variable in length in order to cast linotypes of different lengths,the separatelyformed studs or cores may be screwed into 5 the mouthpiece or otherwise attached in order that one or more of them may be removed when the mold is shortened in length.

In Fig. 3 I have shown the cores as screwed into the body of the mouthpiece that they may other part is employed. between the mold and s the pot. The slag is left undisturbed in the mold, so, that itmay be trimmed to the exact mane height required in the usual manner by a knife acting across the face of the mold.

Having described my invention, what I claim is- 4 1. In a linotype-machine, a slotted mold in combination with a melting-pot having its delivery-mouth adapted to act directly against and close the base of the mold, and provided with one or more studs adapted to enter the mold and to be withdrawn from the mold and from the slug therein.

2. As a new article of manufacture, a mouthpiece for a linotype-machine, adapted to fit directly against and close the rear face of the mold, and provided with perforations for the passage of the metal, and with one or more studs adapted to enter the mold and to be Withdrawn therefrom and .from the slug therein.

3. In a linotype -machine, a mouthpiece adapted to close the rear provided with studs adapted to enter the mold and to be withdrawn endwise therefrom and from the slug therein.

In testimony whereof I hereunto set my hand, this 5th day of February, 1904, in the presence of two attesting witnesses.
