DAVID SHERWOGD KENNEDY, OF BROOKLYN, NEW YORK, ASSIGNOR TO MERGER- IHALER LINOTYPE COMPANY, A CORPORATION OF NEW YORK.

TYPOGRA I-ITCAL MACHINE.

Application filed October 27, 1914.

To all whom it may concern Be it known that I, DAVID SHERWOOD KENNEDY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Typograph cal Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to typographical machines, such as linotype machines of the general organization represented in Letters Patent of the United States No. 486,532, to O. Mergenthaler, wherein circulating matrices are stored in grooved magazines and released therefrom by suitable escapement devices 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 returned through distributing mech anism to the magazines from which they started.

More particularly, it relates to the con struction of the magazines and specifically of the grooves therein, as will appear more fully from the subsequent description and claims.

In the accompanying drawing, I have shown my invention only in preferred form and by way of example, and as applied to a linotype machine, but obviously many changes and variations may be made therein, and in its mode of application, which will still be comprised within its spirit. Similarly, it may be adapted to other kinds of typographical machines, such as typesetters, typecasters and the like, which handle type or dies, 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.

Referring to the drawing: Figure 1 is a longitudinal section through the magazine and the adjacent parts of a linotype machine, with my improvements embodied therein; Fig. 2 is a perspective of a portion of the magazine, etc; Fig. 3 is a section on the line 3--3 of Fig. l; and Fig. 4: is a similar view of an arrangement now in use.

Specification of Letters Patent.

Serial No. 868,793.

The matrices X are as usual stored in the magazine A and are released therefrom by the escapements B and pass into the raceway 0 on their way to the other assembling devices, all in the ordinary manner. The escapements are actuated by the reeds D, which in the form shown extend across the front of the magazine so that the matrices are forced to pass between them, in a manner similar to that presented in a number of commercial machines. The parts so far described are or may be of any desired or improved construction, and in themselves constitute no part of my present invention, except as hereinafter specified.

In ordinary practice, the magazine is in the shape of a trapezium, with its lower or delivering end parallel to its upper or receiving end, but of materially less extent, and with its two sides or edges downwardly converging. The channels therein are constituted by opposing series of grooves in the upper and lower faces, wherein the matrix ears engage and travel, and because of the general contour of the magazine, these grooves also converge from the upper to the lower end; and also in each pair, the lower groove has lain directly beneath the upper one, or in the same plane therewith. In the early form of magazine, it has been provided with top and bottom plates of the same length, and consequently with a rectangular or squared end, so that the grooves in each pair are of the same length; but in magazines of the later type, the end of the magazine has been beveled or cut off at an inclination, as shown in Fig. 1, and as a result the upper groove is materially shorter than the lower one. Due to the general convergence of the grooves, and also the fact that the upper one terminates in advance of the lower one, the continued engagement of the matrix in the extended portion of the lower groove has the effect of delivering it between the escapement reeds out of parallelism therewith, and thus requiring an undue separation between them. The result of this old arrangement is indicated in Fig. 4c, wherein the magazine A is formed with the usual upper and lower grooves E and F and wherein due to the greater extent of the grooves F the matrices X are delivered between the reeds D out of parallelism therewith, or, as it appears in the plane of section, tilted with respect thereto, and thus involving a material waste of space.

In order to correct the difficulty, and referring now to Figs. 1, 2 and 3, the grooves E and F in the upper and lower plates are relatively offset or staggered, as best shown by the heavy and light dotted lines in Fig. 2, the lower grooves F being no longer in the same plane with the upper grooves E, but slightly inclined therefrom to the right, with the effect that the engagement of the longer lower groove with the matrix tends to alter its relative position and to ring it into parallelism with the reeds as it passes between them. This result is best indicated in F ig. 3, in which, when compared with Fig. 4, it will be seen that the ends of the lower grooves have been in effect shifted to the right in relation to the ends of the upper grooves, and so as to bring the matrices into parallelism with the reeds, as appears in the plane of section. In this manner, the waste of space is prevented, and as a result thereof either the reeds may be located nearer to each other in connection with the same width of matrix, or if they be located at the formerdistance from each other, there will be ample space for much thicker matrices to pass between them.

This construction corrects a difiiculty long existent in connection with magazines provided with the earlier arrangement of grooves, and particularly adapts the magazine to modern conditions, wherein larger matrices are often employed, or where for other reasons it is desirable to avoid the waste of space.

As previously stated, I have shown my invention only in preferred form and byway of example, and as applied to a specific type of mechanism, but obviously many modifications and alterations therein, and in its mode of adaptation, will suggest themselves to those skilled in the art, without departure from its scope.

Having thus described my invention, its construction and mode of operation, what I claim and desire to secure by Letters Patent of the United States, is as follows:

1. A magazine for typographical machines formed with two opposing series of grooves, some of the grooves of one series being offset or staggered with relation to the corresponding ones of the other series, for the purpose described.

2. A. magazine for typographical machines beveled at its lower end and formed with two opposing series of grooves converging toward its lower end, some of the grooves of one series being staggered or offset with relation to the corresponding grooves of the other series.

3. A magazine for typographical machines formed with two opposing series of grooves converging toward its lower end, the degree of convergence of one series of grooves being less than that of the other series.

a. In a typographical machine, the combination of a magazine beveled at its lower end and formed with two opposing series of grooves converging toward such end, and a series of escapement actuating devices eX- tending across the beveled end of the magazine, the said magazine having some of the grooves of one series offset with relation to the corresponding grooves of the other series.

5. In a typographical machine, the combination of a magazine beveled at its lower end and having channels converging toward such end, and a series of escapement actuating devices extending across the beveled end of the magazine, the said actuating devices and the magazine channels being relatively arranged so that the side faces of the type or matrices will lie parallel with the side faces of the actuating devices, as they pass therebetween.

In testimony whereof, I have affixed my signature in presence of two witnesses.

DAVID SHERWOOD KENNEDY.
