LINOTYPEFMACHINE.

SPECIFICATION formingpart of LettersPatent No. 605,701, dated June 14, 1898.

Application iled July 14, 1897.

To a/ZZ whom it may concern.'

Beit known that I, PHILIP T. DODGE, of New York, county of New York, and State of New York, have invented a new and usefulV Improvement in Linotype-Machines, of which .keep the forms standing for long periods of time, and as these slugs are commonly made solid-that is to say, without openings or recesses of any kind in them-a large investment is necessary for metal.

The object of my invention is to reduce the consumption of metal by producing slugs with cavities in the base; and to this end the invention consists in an improvement in the mold and ejecting devices adapted for use in the Mergenthaler and analogous machines.'

Referring to the drawings, Figure l represents in perspective a slug. produced by my means. Fig. 2 is a perspective View of the mold in which the slug is formed, together with the ej ector-blade for removing the slugs. Fig. 3 is a cross-section of the mold on the correspondingly-numbered line of Fig. 2. Fig. 4. is a longitudinal section through the mold from end to end on the correspondingly-numbered lines of Figs. 2 and 3.

The slug represented in Fig. lis a solid cast-metal body typehigh and provided on its upper edge with a series of type characters adapted to print an entire line. It differs from the slug commonly in use only in that it is provided in the base with cavities a. These cavities may be varied in form and number at will, provided onlythere is sufficient metal left in the body and base of the slug to give proper support to the type at thev surface in order that they may not sink under the pressure applied to them when in use.

The slugs as above describedcannot be pro. duced in molds of the ordinary form, which have an unobstructed slot or opening from one end to the other, so that'a solid ejectorblade may be passed therethrough.

In order to produce the improved slug, I provide the solid slotted mold B, which in all other respects is of ordinary construction, with two internal blocks or lling-pieces h, which are pinned fast or otherwise secured in Serial No. 644,503. (No model.)

place. These blocks stand iiush with the mold on the rear side and extend through it but part way to the front, as plainly shown in Figs. 3 and 4:. When, therefore, the mold is filled'with molten metal, as usual, to produce the slugs, the blocks b form the cavities in the base,while the front or top edge of the slug, bearing the type characters, is continuous and unbroken. The mold thus formed presents na smooth unbroken rear face and serves to hold or support the slug while the trimmingknife is passing over its base from one end of the mold to the other, as usual.

In order to effect the ejection of the slugs, I employ an ejector-blade which is slotted or forked longitudinally, so that it presents a n'umber of arms to pass through the mold. The ejector may be made, as shown, of a single plate or of a series of separate blades or arms, as indicated by the dotted lines in Fig. 2.

It will be understood that the mold and ejector herein shown are adapted for use in the ordinary Mergenthaler linotype-machine in the same manner that the ordinary molds and ej ectors are used therein and that in all other respects the machine may be of the customary construction.

The essence of my invention resides in the mold adapted to form cavities inthe base of the slug and in an ejector having two or more arms to effect the delivery of the slugs.

I am aware that in the so-called Rogers typograph-machine a mold adapted to open and close was recessed at the base to admit the conical mouth of the melting-pot, which produced a central cavity in the base of the slug. Such construction is not, however, applicable in the Mergenthaler machines or analogous machines using solid molds. I believe myself to be the first to incorporate in the linotype-mold parts or members adapted to produce cavities in the base of the slug and the first to combine with a solid linotypemold having a plurality of openings through its base an ejector having a corresponding number of iingers or branches adapted to enter the mold from the rear and eject the slugs from the front. f

Having thus described my invention, what I claim isl. A linotype-mold having at the front an unobstructed slot or opening, and at the rear IOO one or more filling-pieces forming` part thereof to produce cavities in the base of the slug or linotype.

2. A linoi'ype inold having a continuous slot or opening at its front to produce a slug with an unbroken face, and having the back closed for a portion of its length with two or more openings for the admission of an ejector.

3. A linotype-lnold coutainin g an elongated slot or mold proper, its face adapted to coperate with a series of matrices, and its rear side having a plurality of openings7 in coin-
