Abstract: 12,507. Degener, H., and General Composing Co. May 23. Assembling matrices.-Relates to means for composing from multi-face matrices, wherein the matrices are received on the upper fixed ledge 2, Fig. 1, of the assembler-elevator, and the selection of face is effected by arresting the assembler-elevator at different levels. According to the present invention, the pin 4 that releases the line-transferring devices is used also for arresting the assembler elevator, and for this purpose is adjustable by means such as a lever 5. According as to whether the lever is set in the dotted or the full line position, the pin 4 releases the transferring-devices at or before the normal time, and arrests the assembler-elevator in the normal position for italics, or in a lower position for the ordinary face. The hook 7 for locking the assemblerelevator is provided with two teeth. In setting mixed matter, the bracket 8 is folded down, and the matrices for the ordinary face are turned in the usual manner on to the bottom fixed ledge 3, the assembler-elevator then moving up to the normal level determined by the pin 4. To provide means for transferring the spacers to the casting-carriage at the same level, whether the assembler-elevator has been arrested in the normal or the lower position, the groove 85 for the spacers is widened at the entrance. In the arrangement shown, when the assembler has been brought to the lower position, the spacers slide up the entrance to the groove and are thereby brought to the constant level. Preferably, however, the groove 85 is arranged to depress the spacers when the assembler-elevator has been raised to the normal position, thereby decreasing wear on the spacerlugs, as the number of italic and mixed lines is much less than the number of ordinary lines. In this arrangement, the rail 8 which receives the spacers is arranged higher than the normal level by the distance between the two faces. Clamping matrices.-(1) The screw 19, which operates the movable jaw 22, is mounted in a nut which is adapted to be released to permit a quick adjustment. The nut preferably consists of two members 24, 25, which are held together by springs 28 and may be moved apart to release the screws by means of a rotatable rod 26, having a flat which is seated between the members. The link 34, forming part of the usual justifying-mechanism, is pinned to a split sleeve 32, which is clamped by a nut to a bush 31 having a feather 30 which engages a longitudinal groove 29 in the screw 19. The screw has a pitch, such as a half unit, commensurate with the typographical unit; and the adjustment of the jaw for another length of line may generally be made by releasing the nut and moving the screw longitudinally through a certain number of threads. In the case of an adjustment for smaller fractions of a unit, it is necessary also to release the sleeve 32 and to effect the fractional adjustment by turning the screw. (2) The movable jaw is provided with a spring-pressed slide which prevents the matrices from turning when the line is slack, the slide being pushed back flush with the end of the jaw during justification. In the arrangement shown in Fig. 8, the jaw 22 is dotted to receive the slide 312, which is engaged by a spring 313. When the line is brought forward by the fingers 316, the slide is in the position shown in dotted lines, and is engaged by the left finger and pushed back as far as is required by the length of the line. When the line is carried downward between the jaws, the slide engages the matrices and prevents them from turning. During justification, the spring 313 is compressed, and the slide is pushed inwards until it is flush with the cheeks of the jaw. In making repeat castings, the slide is locked back so as to prevent the line of matrices from being formed when they are brought down for the second and the following casts. The locking-device may consist of a spring-supported lug adapted to engage a pin 314 on the slide, the lug being outside the normal travel of the slide, but being adapted to engage the pin when the slide is pushed in by the operator beyond the flush position. In the arrangement shown in Fig. 12, the slide 312 is controlled by the casting-carriage 343 instead of by the fingers 316, the arrangement being such that the spring pressure is not exerted until the line of matrices is partly within the jaws, thereby preventing the slide from fouling the line of matrices when repeats are being cast. For this purpose, the slide 312 is carried by a spindle 337, which is engaged on opposite sides by springs 339, 340. The spring 340 is stronger than the spring 339, and is engaged by a plunger 341 having a bevelled end arranged in the path of a bevelled plate 344 on the casting-carriage 343. When the line of matrices has been partly seated between the jaws by the carriage 343, the plate 344 engages the plunger 341 and forces the slide 312 yieldingly against the matrices. During justification, the slide is pushed inwards until it is flush with the end of the jaw. The jaw 22 abuts as usual on the stop 21, Fig. 4, or 29, Figs. 8 and 12, so that the jaw may be moved across the mouldslot when reglets are being cast; in the arrangement shown in Fig. 12, the jaw is formed with a slot to receive the plate 344, so as to preserve an uninterrupted side.
