Abstract: 15,058. Albrecht, C. July 5. Linotype machines. - Relates particularly to machines having two or more matrix magazines, any one of which may be operated from one keyboard, and to which the used matrices are automatically distributed. Fig. 3 shows in vertical section, the lower parts of two magazines 1, 2, either of which may be brought into use. On the lower end of each magazine is a set of escapements 6 or 7 pivoted at 52. The matrices 17 liberated by the escapements pass through a slotted guide 10 and channels 44 to the usual assembling-devices. In place of the double guide-channels 44, a single pivoted set of guides may be employed. The ends of the escapement levers are engaged by projections 15 on bars 8 sliding in slots in the guide 10, and connected to levers 11 operated by the rods 12 connected with an ordinary keyboard and operating-mecbanism, which may be such as is described in Specification No. 24,603, A.D. 1894. Springs 18 operate the escapements when the rods 8 are raised, but the springs 55 which are connected to the rods 12 are strong enough to overcome the springs 18. Either set of escapements may be rendered inoperative by turning a shaft 41, having a flattened side, so that the round side engages and prevents the operation of the levers 6 or 7. The two shafts 41 may.be connected by gearing so as to be operated simultaneously, to throw one set of escapements into, and the other out of, action. Other means may be employed for rendering the escapements operative or inoperative. In one of these, the ends of the levers 6, 7 engage notches in the rods 8, and the rods are arranged to rock on a pivot to engage either set of notches and disengage the other set. In another arrangement, the ends of the levers 6, 7 similarly engage notches in the rods 8, and the pivot shafts 52 of the levers 6, 7 are movable so that the levers may be moved out of or into engagement. The means for moving the shafts 52 may consist of rack-and-pinion devices so arranged that, when one set of levers is moved out of engagement, the other is moved into engagement. In another arrangement, the escapements are operated by two sets of levers and rods 12, and the rods 12 are operated by one set of movable actuating-rods. The magazines are independently removable, together with their escapements 6 or 7, and may be independently supported in any suitable manner. The lower end of the lower magazine 1 is preferably supported by the guide 10 which is made L-shaped in cross-section, and the upper one 2 may be separated from the lower one by distance-pieces and supported on them. Before the removal of the magazine, they are moved endways to withdraw the escapement levers 6, 7 from engagement with the rods 8. For this purpose, the magazines may be slidably arranged, and the lower one may be moved by a pin and lever or cam arrangement. A hook or catch may be provided to hold it when moved. The upper magazine 2 may be moved by projections thereon engaging projections on the lower one. Each magazine is provided, at the upper end, with a channelled guide 78 or 79, Fig. 14, by which the matrices, as they drop from the distributing-rails 80, 81, are guided to the grooves or channels of the magazines. The guides 78, 79 may be carried by a frame 82 pivoted at 83 on the fixed frame, so that the guides 78, 79 may be thrown back and removed, when it is desired to remove the maga zines. A distributing-mechanism similar to that described in Specification No. 17,753, A.D. 1902, may be employed, in which the two sets of matrices are separated by dovetail side notches in the matrices, and similarly-shaped diverging bars, by which the matrices are carried to the bars 80 , 81 and screws 50, 51, Fig. 14. Another arrangement of distributing - mechanism is shown in Fig. 18. For use in this, the matrices of one set or magazine are formed with cut-away shoulders 90, so that they are supported at a lower level than those of the other set as they are all guided to the first distributing - bar 80. The set of matrices with the cut shoulders 90 do not engage the bar 80 and screws 50, 94, and fall into a channel 92, in which they are moved laterally by a lever 97, and are then lifted by the slide 103 and fed to the distributing-bar 81 and screws 94, 96, 95 of the other magazine. Two cams on the screw 96 operate the matrix lifters and the lever 97.
