JOHN R. ROGERS, OF BROOKLYN, NEW YORK, ASSIUNOR 'lO NERGEN- THALER LINOTYPIC OOM PANY, A CORPORATION OF NEW YORK.

MACHINE.

SPECIFICATION forming part of Letters Patent No. 768,910, dated August 30, 1904.

Application filed March 28, 1904.

To (zi/Z whom it may concern.:

Be it known that I, JOHN R. ROGERS, of Brooklyn, county of Kings, and State of New York, have inventedanew and useful Improve ment in Linotype-Machines, of which the fol* lowing is a specification. l

My invention relates to linotype-machines wherein linotypes or line-printing slugs are produced in a slotted mold which receives molten metal from a melting-pot on one side, While it is closed on the opposite side by an assembled or composed line of matrices bearing type characters in the order in which they` are to appear in print.

The aim of my invention is to adapt the machine to produce the type characters on the slug in one style or another as demanded.

To this end it consists, essentially, of matrices each of which has two or more characlters differing in style or design, with a mold havingva like number of slots or cells to cooperate with the respective characters, and means for delivering the molten metal or its equivalent into one of the mold-slots or another, as desired.

In the drawings I have shown my invention as embodied in a linotype-machine of the character represented in Letters Patent of the United States No. 679,481; but it will be understood that it is applicable in any and all machines in which the linotypes or slugs are cast against a line of character-matrices.

I have limited the drawings to those parts of the machine which are necessary to an understand ing of my invention. The other parts may be constructed in the manner represented in the patent above referred to or in any equivalent manner.

Referring to the drawings, Figure 1 represents a vertical section through the casting mechanism with the parts in operative position. Fig. 2 is a similar section with the pot, mold, and matrices separated subsequent to the casting action. Fig. 3 'is a cross-section on the line 3 3 of Fig. 2. Fig. 4c is an elevation looking in the direction of the arrow 4, Fig. 2.

Referring to the drawings, A represents the Serial No. 200.362. (No model.)

rigid main frame o1" the machine, and B B-a series of fixed endless guides.

O C represent a series of matrices suspended from the guides and arranged to traverse tbe same, first, lndividually from the storagepoints to the assembling-point, thence in the form oi a composed or assembled line to the casting-point, and, finally, from the castingpoint to the points from which they started, in the manner explained in the patent above referred to.

D is the mold, cooperating with the composed line of matrices to form the slugs or linotypes, and E is the meltingpot, from which molten metal is delivered to the mold.

rlhe matrices instead of having, as in the previous patent, one letter or character each are now constructed with two letters or characters c c'. These may be different characters; hut under ordinary circumstances each matrix is provided with the same character in two different forrns-as, for example, the letter A in a light or text face and the same letter in a heavy or bold face suitable for headings, &c.

The mold D instead of being constructed, as heretofore, with a single slot or cell is now constructed with two parallel slots or cells d d', so arranged in relation to each other and to the characters on the matrices that when the moldis presented against the matrices in the casting position (shown in Fig. l) one of the mold-cells will aline with thelower series of characters, while the other will aline with the upper series.

The pot E is mounted to swing to and from the mold around a horizontal snpportingshaft or axis F. Instead .of mounting this shaft rigidly in the frame, as heretofore, I now mount it in a rotary yoke having eccentric ends or journals G, which are mounted in the main frame, so that by imparting a rotary motion to the yoke by the handle g thereon it is caused to raise or lower the pot, which may thus be adjusted to deliver metal into .the upper or the lower mold-cell, as desired. By thus changing the position of the pot and casting in one cell or the other I am enabled to produce the slug with the type characters l chines. rI`his feature constitutes no part of g my invention.

located in the lower position in the matrices,

or, on the other hand, with type characters lol cated in the upper position in the matrices. In other words, by simply raising or lowering the pot and without changing the position of the other parts I am enabled to produce slugs bearing type characters of one style or another, as demanded.

The mold is carried b van arm I), supported at its lower end on a shaft CZ, having both an axial and a rotary motion, thus permitting the mold to move toand from the matrices, as heretofore, and also permitting it to swing laterally from the casting position downward to a position such as shown in Fig. 4t, that the slugs may be ejected.

The essence of the invention consists in combining with the matrices, each having two or more characters, a mold having a corresponding number of slots or cells and means whereby the molten metal may be delivered into one mold-slot or another at will.

It will of course be understood that the pot may be supported in any manner which will admit of its being raised and lowered and that the means for effecting its support and its adjustment may be varied at will.

Locking devices such as are commonly used for like purpose may be employed in connection with the turning-yoke to hold it in its different operative positions. These features constitute no part of the invention.

My invention is of course applicable not only to machines which cast slugs for printing entire lines, but also .to those which produce shorter slugs and to machines for producing logotypes.

Slugs may be ejected by any suitable meehanism-for example, two reciprocating blades, such as are ordinarily used in linotype-ma- Having thus described my invention, what I claim is- 1. In a linotype-macliine, the combination of matrices having two characters each, a mold having two corresponding slots, and a metaldeliveringmechanism adjustable to deliver to one slot or the other` as required: whereby the machine is adapted to produce linotypes with different type-faces.

2. In a linotype-machine, the combination of matrices having two characters each, a mold with two slots or cells1 means for presenting the same with the respect-ive slots in alinement with the respective matrix characters at the same time, and a melting-pot having its mouth adjustable to deliver metal to one moldslot or the other, only, as demanded.

3. In combination with a linotype-mold having two slots or molds proper, a metaldelivering mechanism adjustable at will to deliver to one slot or the other.

4. The combination, in a linotype-machine, ot' the lixed guides, the traveling matrices suspended therefrom and each containing two separately-usable characters, the mold having two slots and arranged to l'present them to the respective matrix characters, one at a time, the pot having a mouth adapted to close and deliver into one mold-slot at a time, and means for adjusting the mouth to cooperate with one slot or the other.

In testimony whereof I hereunto set .my hand, this 24th day of March, 1904, in the presence of two attesting witnesses.

JOHN R. ROGERS.
