To allwhom, it may concern: n 4 Be it known that LGARL MUEHLEISEN, a citizen of the United States of America, residing at 88 Chausseestrasse, Berlin, l\ 4, in the Empire of Germany, have inventednew and useful Improvements in Matrices or Type-Dies for Use in Typographical Composing-Machines, of which the followingis a specification.

This invention relates to matrices or type dies for use in typographical composing machines such as those known commercially under the trade mark Linotype, and particularly those matrices or type dies which have both normal and variant faces-and are adapted to be assembled in as many different levels as there are difierent faces.

word matrix or matrices tion is to bring So far as the present invention is con cerned a matrix is considered to be the equivalent of a type die, and that being the case, to avoid unnecessary reiteration, the

' as hereinafter employed isintended to apply to either or both of such devices. When the operatorcomposes matrices such as those above particulariz'ed, for forming what is known as a mixed line, that is to say, a line partly of one face and partly of another, it often happens thathe omits to make they necessary adjustment for securing that result at the point of assemblage, and consequently he has, afterward, to raise or lower some of the matrices by hand, to bring them to the desired level in the assembler. In the case of double character matrices, which are assembled at only two different levels, the aforesaid manual change of level presents no appreciable diiiiculty, because the matrices can be tilted forward without moving the upper front supporting ledge, lugs clear the said ledge, at which juncture they can be easily raised to bring those lugs on to the said ledge or lowered to bring the said lugs on to the lower front supporting ledge according to whetfi'er 'tlie alterathe variant or the normal faces into the assembling or casting line. In cases however in which the matrices are provided with more'thantwo faces and the assembler is provided with" supporting ledges at a corresponding-number of different levels, sible, under existing circumstances, to manual ly transfer matrices from say the upper- Specification of Letters Patent.

most ledge to the lowermost one without first withdrawing at least the said uppermost ledge and thereby entirely disarranging the composed line by allowing any matrices which may have been assembled on that ledge to fall on to a lower one.

The object of the present invention is so to construct the matrices, whether provided'with two or more formative cavities, as to enable the aforesaid manual transference to be readily effected without disturbing the parts of the line not to be affected by such transfer, and to that end it consists princip lly in prtwidin each of the matrices with g recess in the edge opposite to that bearing the characteniaces, to allow the said matrix .to be canted over on the lug below sucln recess, sufficiently to enable that lug to clear the supporting ledge above or below it and without withdrawing any of the upper supporting ledges.

The invention will behest understood reference to the accompanying drawings in which it is shownin connection with a triple character matrix; this, however is given merely as a convenient example and it is to be understood that the said invention is equally applicable to matrices having two or other lurality of characters.

In tlie said drawing :Figure 1 is a side view ofthe said three-character matrix constructed according to this invention, and Figs. 2, 3 and 4 are views showing the said matrix in three respectively different positions in the assembler or assembler elevator, Fig. 2 3 showing it a higher to a lower position or Vice versa, and Fig. 4 showing 'it in full lines in its highest position and in dot-andrdash lines as when being transferred from the lowest to a higher position or vice versa.

The matrix a has three formative aavities b, 6 6. all presenting say the same charactor in respectively difierent faces, such for example as Roman, black letter, and italic. According to whether the face I), 5' or b is to be presented to the mold slot (the dot and-dash line y represents the relative height of the center line of the said slot) so showing it in its lowest position, Fig. 1

as when being transferred from must the matrices be assembled on the lowthe movable rail or of a switch device which constitutes no part of the present invention. Therledges d ande are movable forwardly from thepositions in which they are shown in the. draw'ingsg the means for so moving them are not represented in the drawings astheyconstitute'no part of this invention; any of the means" now i well know n' in the art may be used for the P po 51 Each matrix according to the present invention is provided with a recess f in its front edge that is to say the edge opposite that containing the formative cavities Z2, Z2,

6 this recess being of any such size and shape (not necessarily those shown in the drawings) which will admit of the said matrix beingtilted sufficiently to allow the front bottom lug 9 thereof, to be moved up or down past the back of the rails d and 6 while the latter are still intheir respective rearmost positions.

Assume now that of a line of matrices assembled on the fixed ledges and consequently in positionto present their faces 6 in casting position-some of them should have been assembled on say the rail 6 so that their faces I) would be presented in casting position. To rectify this error the 0persay the ledge e to the ledge '0, the operator 'carries out the said 0 eration in practically the reverse order of t at just' describedi g g.-

the combination of the assembler formed with an openmg .to receive the matrices and provided. with a device projectingthereinto and into close proximity to theedges of the matrices, with the matrices formed with cars and edges between said ears and also with recesses in their said edges to receive the projecting device when the matrices are tilted over or toward it and thus to facilitate the longitudinal adjustment of thematrlces.

also with a recess in said ed 'e to receive the supporting device when tire matrix is tilted over or toward it.
