Abstract: 25,960. Walker, A. H., [Mergenthaler Setzmaschinen-Fabrik Ges.]. Nov. 10 Distributing matrices ; driving - mechanism.- Relates to means for separating matrices or typedies into groups according to face, of the kind described in Specifications 19,713/98 and 14,263/09, wherein the mixed line is threaded on to faceseparating rails. The matrices 7 of one face are formed in the front edge with a notch to engage the separating-rail 11, and the matrices 8 of the other face are formed in the rear edge with a notch to engage the separating-rail 12, the matrices 7, 8 being also provided respectively with open notches 9, 10 so as to clear the opposite separating-rail. The rail 12 is fixed and the rail 11 is movable, the movement being made as short as possible by arranging the distributors 4, 5 one behind the other on the same level and as near together as possible. In the device shown in Figs. 2 and 3, the rail 11 is suspended from parallel links 18, 19 and is actuated by a cam 20 on the cam-shaft 21 of the machine, the link 18 being connected to a link 24 pinned to a lever 22, which is tensioned by a spring 26. The matrix-pushers 14, 15 are actuated by a face cam 27 on the shaft 21, the pushers being carried by slides 32 connected by links 31 to a common lever 30, which is pivoted at 29 and tensioned by a spring 33. When the rail 13 of the second elevator is carrying the mixed line upwards, the rails 11, 12 are held in the approximated position by the cam 20, and the projection 34 on the cam 27 retracts the pushers 14, 15. As the drop 35 is passing the lever 28, the spring 33 causes the pusher 15 to transfer the mixed line from the rail 13 to the rails 11, 12. When the projection on the cam 20 has passed the lever 22, the spring 26 pulls the rail 11 into the position shown, the face 36 of the cam 27 holding the pushers 14, 15 stationary. The lowest face 37 of the cam 27 then allows the pushers 14, 15 to transfer the separated groups of matrices 7, 8 from the rails 11, 12 to the respective distributors 4, 5. The lever 28 which connects the lever 30 to the cam 27 is of U-section and open at the front so as to allow the pushers 14, 15 to be retracted by hand in case of jamming. In a modification, the pushers 14, 15 are formed in one piece, and the rail 11 is carried directly by a bell-crank lever, which is tensioned by a spring and is controlled by a drop in a cam on the shaft 21. In a further modification, the rail 11 is mounted on a slide which is actuated by the lever 22. In the device shown in Fig. 9, the cam 20 is dispensed with, and the rail 11 is moved by the matrix-pusher. The rail is suspended from parallel links 18, 19 and is maintained in the approximated position by a spring 46. The rail is moved by the pusher 42, which is formed with a plate 49 having an incline at the front end adapted to push back a slide-rod 53 pivoted to the link 19. The front edge of the plate 49 is long enough to keep the rail 11 presented to the distributor 4 for the proper time. To compensate for the different lengths of the separated groups of matrices, the pushers 14, 15 may be provided with the compensating-devices described in Specification 5436/97.
