MATRIX FOR LINE-CASTING MACHINES.

Specification of Letters Patent. Application filed June 9, 1910.

Patented Sept. 22, 1914. Serial No. 585,953.

To (ZZZ whom it may concern Be it known that I, HUGH ALFRED SPAR- F greater widths, that is to say, with wider LING Of New Orleans, parish of Orleans,- and State of Louisiana, have invented a! of which the Q like between adjacent matrices when asj in actual practice, and

thaler liuotype machine of the general 'organizaticurepresented in Letters Patent of the United States No. 436,532. These matrices, representing individual characters, are carried in a magazine, from which they are delivered one at a time by a fingerkey mechanism, the released matrices being assembled temporarily in line and presented to a mold to form type characters on a slug cast therein, after which the matrices are returned through a distributing mechanism to the magazine. Each matrix consists 'of a flat rectangular piece of metal having in the upper end a notch containing distributer teeth, and having on the two vertical edges projecting ears or shoulders at the upper and lower ends; These ears or shoulders, which engage with various parts of the machine to sustain and aline the matrices, also travel in the guiding grooves or channels in the magazine plates. In passing downward from the distributer into the upper end of the magazine certain of the matrices pursue latenally curved paths. hen very large or thick matrices are employed the space or; clearance at their sides -is very slight, and it is found that if the. matrices are made with the usual straight parallel ears and upper ends of full thickness they occasionally bind in the channels against one another so that is retarded or arrested.

My invention is designed to overcome this difficulty, and to this end it consists in a matrix having its upper end, including its upper ears, beveled or ch amfered, whereby it is reduced in thickness at one end. In this manner I am able to retain all the features and proportions necessary for the proper handling of a matrix at the various points in the machine, while at the same time I am enabled to handle matrices of and their advance guiding surfaces,

characters, than heretofore, without difficulty.

Another valuable advantage arising from my improvement is the facility which it gives for the insertion of spaces and the sembled. This necessity frequently arises particularly in connection with tabular work, when the beveled or. chamfered upper edges of the matrix permitsthe ready insertion and seating of the spaces or blanks.

In the drawings: Figure 1 is a perspective view of one of my matrices looking toward the front or inactive edge. Fig. 2 is a. perspective view 'of the same looking toward the active end, containing the character or matrix proper. Fig. 3 is an edge view. Fig. 4 is a side view.

Referring to the drawings, A represents the body portion of a matrix, consisting of a flat, generally rectangular plate having parallel vertical edges, one of which contains the intaglio character or matrix proper, a.

a, c of and a represent ears extending edgewise from the matrix at the upper and lower ends, these ears serving to enter the groove or channel in the magazine plates for the punpose of guiding the matrices, and

also serving to engage with the various members of the machine by which the matrices are alined, distributed and otherwise controlled.

The upper end of the matrix is formed with a V-shaped "notch having distributing teeth a therein.

So far as described the matrix may 'be-in all respects of ordinary construction;

I Her'etofore it has been customary to construct all the ears of the same thickness, and with parallel Vertical faces. length of the upper ears is such chines of ordinaryconstruction possible for these cars to follow the curved paths required in entering the magazines from the distributor without binding on the or conflicting with adjacent matricm. In order to overcome this difliculty I bevel, 0r chamfer, the upper end The.

it was irrl- I of the matrix, including the upper ears a and (L in an upward and backward direction, thus reducing the thickness of the upper cars and of the upper end of the matrix, as'shown in the several figures. When thus formed the matrix will follow the various paths required freely and speedily, and without conflicting with other matrices. Although the ears are reduced in thickness at the upper end they are left of the ordinary or full'thickness at the lower ends, or practically so. Their under faces or shoulders, by which the matrices are sustained and alined, remain unchanged. In short, all those surfaces of the ears heretofore employed, and which are necessary for the proper guidance and adjustment of the matrices in their course through the machines, are retained.

When the matrices are of very great thickness I prefer to bevel or chamfer the lower ends as shownat a, this ohamfer being on the opposite side to that at the upper end. This feature is old in itself but when combined with the chamfer at the upper end it gives a matrix such form that it may be handled with rapidity and certainty by the ordinary mechanisms of the machine.

Having described my invention what I claim is:

l. A matrix adapted for circulation in a typographical machine and beveled or chamfered at its upper end to facilitate its guiding during circulation.

2. A matrix adapted for circulation in a typographical machine and formed on its edges with guiding ears, the said ears being beveled or chamfer'ed at their upperends to facilitate the guiding of the matrix during circulation.

3. A matrix adapted for circulation in a typographical machine, and beveled r chamfered at both its upper and lower ends to facilitate its guiding during circulation.

.In testimony whereof I hereunto set my hand this th day of May, 19-10, in the presence of two attesting witnesses.

H. ALFRED SPARLING.
