TYPOGRAPHICAL MACHINE.

Specification of Letters Patent.

Patented Mar. 3, 1914.

Application filed. June 1 9, 1912. Serial No. 704,473.

To all whom it may concern Be it known that I, LUTHER L. KENNEDY, a citizen of the United States, and a resident of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Typographical Machines, of which the following is a specification.

My invention relates to typographical machines, such as linotype machines of the general organization represented in Letters Patent of the United States, No. 436,532, to O. h lergenthaler, wherein circulating matrices are delivered from a magazine in the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the face of a mold, the mold filled with molten metal to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices thereafter elevated and returned through a distributing mechanism to the magazine from which they started. In this particular style of machine, the release of the matrices from the magazine is controlled by escapement devices, and their subsequent deliver to the assembling mechanism is efl'ecte by gravity. It sometimes happens that the matrices are sluggish, or stick in their channels, or are not freed therefrom before the return action of the escapement, which results in their being caught thereby and their delivery prevented.

It is the purpose of this invention to prevent such abnormal occurrences, and to insure and accelerate the delivery of the matrix when it is released by the eseapement, and to this end I provide constantly driven means to engage therewith. Preferably and specifically, these means take the form of a continuously actuated roll, transversely arranged with reference to the magazine and projectin through an opening therein, so as to be in frictional engagement with the matrices next to be delivered. In this way I not only obviate the liability of the matrix to stick or bind in the channel, whether due to dirt or other causes, but also insure its removal before the return operation of the escapement. In addition, I secure the valuable advantage of accelerating the matrix delivery, which is necessarily slower when gravity alone is relied upon, and particularly in cases, like that in the said Mergenthaler patent, where the magazine is tilted or inclined from the vertical.

In the accompanying drawing, I have shown my invention in preferred form and by way of example, and as applied to a special style of machine, but obviously many changes and variations may be made there in, and in its mode of application, without departure from its spirit. Thus, for instance, it may be adapted not only to other kinds of line casting machines, but also to other forms of typographical machines, wherein type or dies are handled instead of matrices. Generally speaking, I desire it to be understood that I do not limit myself to any specific: form or embodiment, except in so far as such limitations are specified in the claims. p

Referring to the accompanying drawing: Figure 1 is a front view of a portion of a linotype machine, having my invention applied thcrcto; and Fig. 2 is a transverse vertical section, on an enlarged scale, through the lower or delivery end of the magazine.

As is usual in machines of this kind, the manipulation of the keys A, through connected means, including devices such as the reeds B, actuates the escapements C, and thereby controls the release from the channeled magazine D of the matrices X, which are delivered to the face-plate E and therethrough to the other assembling devices. The parts and operations so far described are or may be similar to those set forth in the before-mentioned Mergenthaler patent, or as embodied in the commercial linotype machine.

In the particular instance illustrated, it will be seen that after their release by the escapements, the delivery of the matrices is effected by gravity. In order to insure this delivery, and to free the matrices from the magazine before the return movement of the escapements, and also to accelerate them, I have provided constantly operated means to engage therewith, which takes the form of a roll F, coated with rubber or otherwise as may be desired, transversely arranged with reference to the lower or delivery end of the magazine D, and projecting through an opening D therein, in such manner that the roll is in frictional engagement with the lowermost matrices X. It will be seen that the tendency of this continuously exerted force is to expel the matrix from its channel, and that when released by the escapement, it will be delivered with greater certainty and increased speed. The rotation ot the roll F may be-secured in any desired manner, as for instance by the pulley G thereon and the'band or cord H engaging therewith.

As shown in Fig. 2, the roll F contact-s Withthe upper ear: of the matrix X,.andis also 1n position to engage nnmediately with the matrix X next in series, so that the latter Will be shifted in. the same Way to take the place-of the delivered one;

As previously pointed out; I have shown my invention in preferred form and by Way of example, but obviously many changes and variations therein, and inits mode of -matrices to permit the action of said means.
