TYPE 0R MATRIX.

To all whom it may concern: 7

Be it known that I, Fnneos F. WiLsoN, 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 Type or Matrices, of which the following is a specification, reference beinghad therein to the accompanying drawing.

My invention relates to type or matrices for typographical machines, such as linotype machines of the general organization represented in Letters Patent of the United States, No. 6,532, to O. Mergenthaler. In machines of this class, the matrices are released from their magazine by the manipulation of a keyboard mechanism, and are then assembled in line and presented to a mold, wherein the slug or linotype is cast. After this, the matrices are distributed and restored to the magazine from which they started.

It frequently happens, and particularly in the case of very large or display matrices, that their weight, and consequent impact when arrested, causes wear of the machine parts and of the matrices themselves. The problem has been to lighten them suffi ciently, but at the same time to leave sup port for the wall containing the formative character, so that when the matrices are as sembled in line, they will retain the dimensions required, and the characters cast therefrom will be of the exact height desired. To this end, they are ordinarily constructed in skeleton form, or more specifically, longitudinal cuts or grooves are made in them to remove as much metal as possible. ()ther difliculties consequently arise, and particularly in that not only do the walls spring inwardly, due to the cutting or milling of the grooves, but also their strength is diminished. I therefore provide these skeleton matrices with means for reinforcing the outer walls, and preferably by inserting strengthening members in the cuts or grooves in the rear of the characters.

I have illustrated my invention as applied to a very large or thick matrix of the display kind, but many changes and variations may be made in the mode of application, and also in its form, which will still be comprised within its spirit. Similarly, the invention may be adapted to type Specification of Letters Patent.

or dies, as. well: as t0v 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 assuch limitations are specified in the claims.

The accompanying drawing illustrates the several steps employed in the production of the matrix, Figure 1 showing a solid blank with the character punched therein; Fig. 2, the blank with transverse holes drilled therein; Fig. 3, a section on the line 3-3 of Fig. 2; Fig. 4, a side view with the reducing slots formed therein; Fig. 5, a section on the line 5-5 of Fig. 4; Fig. 6, a section on the line 6-6 of Fig. 7 and Fig. 7, a perspective of the finished matrix.

The matrix X is first formed as a solid blank(Fig. 1) and provided in its edge with the formative character X Transverse pin holes D are then drilled therein, in the rear of and in a plane intersecting the character X (Figs. 2 and 3). Next the longitudinal reducing grooves or cuts A, of a depth approximating the thickness of the matrix, are formed, leaving the central wall B and the two exterior walls C, and also the outer portions of the holes D (Figs. 4 and 5). It will be noted that this operation results not only in weakening the blank, but also in springing the walls C inwardly and consequently out of parallelism. To correct these difficulties, namely, in order to reinforce the skeleton structure, and to restore the walls C to their proper spaced relation, I insert the strengthening elements E (Figs. 6 and 7) between the outer walls 0 and the inner wall B, these elements being preferably in the form of solid cylinders or pins E, located in and held in position by the recesses or notches constituted by the remaining portions of the pin holes D. As a result of this procedure, not only is the matrix lightened, but also given the strength necessary to perform its functions properly.

As previously stated, I have shown my invention only in preferred form and by way of example, and as applied to a specific style of matrix. However, many modifications and alterations therein, and in its mode of application, 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. The type or matrix X formed in its side face with the longitudinal grooves A, and presenting outer Walls C constituting the edge portions of the matrix body, and the intermediate Wall B, and provided with the elements E located in said grooves and serving to maintain the Walls in proper spaced relation.

2. The type or matrix X formed in its side face With the longitudinal grooves A,

each having in its opposing faces cylindrical recesses D, the said matrix being provided with the cylindrical reinforcin elements E fitting in the recesses of the grooves A and serving to maintain the outer Walls C in their separated condition. In testimony whereof I have affixed my signature in presence of two witnesses.
