Abstract: 21,898. Mergenthaler Setzmaschinen- Fabrik Ges. Nov. 9, 1909, [Convention date]. Assembling and distributing matrices. - In composing from multiple-face matrices (or dies), the usual setting-switch in the assembler and the retractable slide in the first elevator are dispensed with, the selection of face, when composing entire lines in the same face, being effected by adjusting the levels of the organs concerned in the transference of the matrices. Fig. 1 shows an arrangement for composing in either but not both of two faces. The assembler 6 is formed with a single fixed guide 35, the channel 10 with fixed guides 18, 19, the first elevator with fixed guides 20, 21, and the channel 13 with a fixed guide 22. The level of the assembler with regard to the channel 10 is determined by a stop 9 or by a movable stop 23, which, when operative, projects below the stop 9 by a distance equal to that between the faces of the matrix. According as the stop 9 or the stop 23 arrests the assembler, the matrices move along the top guides 18, 20 or the bottom guides 19, 21, and present the bottom or the top faces to the mould. The level of the elevator 11 with regard to the channel 13 is determined by stops 12, 25. The stop 25 may be connected by a link 26 to the lever 24, which constitutes the stop 23. The stops 23, 25 may be carried by the assembler and the first elevator, in which case the stops would be independent. When the matrices stand on the guide 20, the stop 25 is in position to arrest the elevator with the guide 20 in alinement with the guide 22. When the matrices stand on the guide 21, the stop 12 arrests the elevator with the guide 21 in alinement with the guide 22, the stop 25 having been moved back by the setting of the stop 23. If the matrices have more than two faces, additional stops 23, 25 are provided. Fig. 6 shows an arrangement for composing in either or both of two faces. The assembler 6 is formed with fixed guides 16, 17, the matrices always being assembled on the top guide. According as to whether the stop 9 or 23 arrests the assembler, the matrices move along the top guides 18, 20 or the bottom guides 19, 21, and present the bottom or the top faces of all the matrices to the mould. The stop 25 is dispensed with, the elevator 11 being arrested invariably by the stop 12 with the guide 21 in alinement with the guide 22. When the matrices stand on the top guide 20, they are brought down by the known depressor 15 in the channel 13. In composing mixed matter, the matrices are assembled on the top guide 16, and the matrices which are required in the top face are then moved down on to the guide 17, the assembler being then moved up to the stop 9. In the device shown in Fig. 9, the assembler is arrested invariably by the stop 9, and adjustment of level is obtained by mounting the guide 27 on a transverse pivot 28 so that the delivery end may be set, as by a handle 29, to register with either of the guides 18, 19 in the channel 10. For mixed copy, the guide 27 is formed with as many guide ledges as there are faces. The guide 27 may be placed in any of the other organs except the first elevator.
