Distributing matrices.-In composing-machines, either alone or in connexion with casting-apparatus, which are capable of producing single letters, syllables, words, or complete lines, and employ matrix-bars composed of two or more relativelymovable parts, all matrix bars, the lengths of which have been changed from the normal, are forcibly returned to their normal length after composition, before starting a fresh composition. Fig. 2 shows a matrix-bar comprising two parts a, b enclosed by a sleeve c and slidable upon one another ; the part a bears two formative cavities, and the part b is suspended from a guide-wire d. The matrix-bar is shown in its shortened condition with the lower cavity opposite a mould. After casting, a lever e returns the bar to its full length. There need not be a separate lever e for each matrix-bar ; a pair of such levers may support a striking-rod for engaging any number of the matrix-bars Instead of moving the lower part of the matrix-bar relatively to the upper part, the upper part may be moved. In this construction, the two parts are connected by means of toggle links, and the links are straightened when the member supporting the guide wires is raised by the lever or levers e. Before starting a fresh composition, the guide-supporting member is lowered again. Fig. 8 shows a further modification in which the hooked supporting-part b of the matrix-bar is pivotally connected with the part a, and Fig. 9 a modification in which a spring m, instead of a lever e, serves to return the matrix-bar to its normal length. In a modification of the construction shown in Fig. 2, a spring may be provided in connexion with the two parts of the matrix-bar. Tension, compression, blade, or torsion springs may be combined with the various modifications.
