MATRIX FOR CASTING SPACES AND QUADS.

Specification of Letters Patent.

To a whom it may concern.-

Be it known that. we, FRANK H. BROWN and JOHN E. HANRAHAN, of the city of Baltimore and State of Maryland, and GEORGE A. BOYDEN, of Mount Washington, in the county of Baltimore, State of Maryland, citizens of the United States, have invented certain new and useful Improvements in Matrices for Casting Spaces and Quads, of which the following is a specification.

This invention relates to a matrix from which type spaces and quads are to be cast; and the object of the invention is to provide a matrix for this purpose which may be used in the same mold in which the type with char acters are cast.

It is to be understood that spaces and quads should be shorter in length than types having projecting characters, and in order to cast such shorter spaces and quads in the same mold-cavity that is employed to cast the types with the characters the length dimension of the cavity must be shortened. By this invention, therefore, we provide a space and quad matrix plate having on its casting side a boss which when brought into the position to close the end of the mold-cavity will project or take into said cavity and shorten the latter to the extent to which it has entered said cavity. Thus the length of the mold-cavity having been shortened tlxe type-bcdy cast therein will be correspondingly shortened, and these type-bodies con stitute the spaces and quads.

The construction or operation of the mold parts is immaterial, it being understood that when they are in the casting position the improved matrix Will have position at one end of the moldcavity, and the boss or projection on the matrix will enter said cavity.

The invention is illustrated in the accompanying drawings, in which- Figure 1 illustrates a face view or front elevation of a space or quad matrix, and Fig. 2 illustrates a side or edge view of the same.

The improved matrix consists-of a plate 1 of such dimensions as to readily coact with the mold mechanism. The bro ad flat side of this matrix-plate, which is to seat against the 50 end of the mold-cavity, is provided withaproor boss 2, which is to enter the moldcavity, thereby shorten its length dimension. The flat outermost face of this projection or boss forms the top or end of the quad or space that is cast in said cavity. The vertical dimension between 3 and 4 represents the bodywise size of the space or quad, and all sides of said boss are spaced from the edges of the plate.

It will be understood that any size projection or boss may be on the matrix-plate.

By this invention changes can be rapidly made to cast spaces and quads from the same mold mechanism that produces type characters.

This invention enables spaces or quads to be produced from the same mold mechanism that casts the type of the same bodywise size and without requiring skilled adjustment of the parts, it only being necessary to remove the matrix which has the type character and substitute the improved space or quad matrix.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. A matrix for individual-typecasting machines, comprising a plate having at its broadest fiat side a projection or boss of smaller dimensions than the said flat side of the plate and all sides of said boss being spaced from the edges of the plate, whereby a space or quad of a size equal to the outermost face of the said boss may be cast in an ordinary type-mold cavity.

2. A matrix for converting an ordinary type-mold cavity into a cavity for casting spaces or quads, comprising a fiat plate having at its broadest side a rectangular boss adapted to shorten the length dimension of said mold-cavity.

In testimony whereof we affix our signatures in presence of two witnesses.
