Abstract: 16,860. Boult, A. J., [Typograph Ges. Setzmaschinenfabrik]. July 23. Linotype machines.-Relates to machines of the kind known as the "typograph," and consists in (1) means for adjusting a line of matrices at the casting point, and (2) means for enabling two-character matrices to be used. (1) Each matrix 4, Fig. 2, has in its front edge notches 7, 7<1> and in its rear edge a notch 8 which is engaged by a fixed strip 9. The matrices are alined in an horizontal direction by a rotatable rod 25 carrying a strip 26 which enters the notches 7 of the matrices. Should a matrix of the line be improperly placed and fail to engage the strip 9, the strip 26 will be unable to enter the notches 7 and the operation of the machine will be prevented. 'The matrices are alined in the vertical direction by an arm 11 pivoted to the rotatable mould-holder 10, Fig. 5. When the mould moves towards the matrices, the arm 11 enters the notches 7<1> and presses the matrices against the underside of the strip 9. When two-character matrices are used, two notches 8, 8<1> are provided for engagement by the strip 9 and an incline 7<2> to permit of the action of the strip 26. (2) The matrix basket A, Fig. 1, is carried by a shaft 1 and can be rotated by means of a handle 6 so that the matrices of an assembled line slide back into normal position along their supporting - wires 3. The shaft 1, Fig. 4, is movable endways in its bearings 22 to permit of the matrix basket being moved into or out of gear, i.e. towards or away from the fixed frame B conveying the strip 9 which engages the notches 8, 8<1> of the matrices. The matrix basket is moved into gear by a spring 28, and is normally held out of gear by a lever 30 carrying a pivoted arm 32 one end of which bears against a roller 33 on the frame B. Depression of a rod 35 by means of a coupling-rod 16, Fig. 1, tilts the arm 32 and permits the basket to be moved into gear by the spring 28. When the lower characters of the matrices are to be used in a line or part of a line, these matrices are raised, before they engage the strip 9, by means of an inclined plate 14, which is moved into their path. The matrix basket is thrown into gear by rotation of the coupling-rod 16 which causes a cam 34 to depress the rod 35. A cam 17 on the rod 16 acts through a slide 19 and a lever 18 to project the plate 14 into the path of the matrices. A stop pin 15 is simultaneously projected by a lever 20 having at one end an incline 51 agaiost which bears a lever 46, which is supported by the matrix basket A. The inclined plate 14 is withdrawn, when the upper characters of matrices are to be used, by backward rotation of the rod 16. The stop-pin 15 is withdrawn after the composition of each word, by depression of the space-key which is connected by a lever 62 and a rod 64 to the lever 20. The words are successively pushed on to the strip 9 by a rocking arm 66, Fig. 1, which is automatically connected to the space-key when the matrix basket is thrown into gear. When the whole line has been composed, the pin 15 is withdrawn by depression ot the rod 16 and the machine is started. A hook on the rod pulls down a lever 44 which lifts the lever 46 so that the incline 51 can pass beneath it. A spring 52 thereupon rocks the lever 20 and retracts the pin 15. After the casting of the line, the basket is thrown out of gear by a hook 37, Fig. 5, pivoted to the rotating mould-hol ler 10. As the mould moves away from the matrices, the hook 37 engages a projection 38 on the lever 30, which is thereby rocked. A spring restores the arm 32 to normal position with its end on the roller 33. If the same line is to be cast again, the basket is prevented from being thrown out of gear by a nose 40, Fig. 4, which is projected into the path of the hook 37 by a lever 39. When an entire line is to be cast from the upper characters of the matrices, the basket is left out of gear during assembly, and is put into gear before casting by depression of the rod 16, which in turn depresses the rod 35. The suspension eyes of the matrices are revoluble in known manner so that the matrices may be raised without leaving their supporting-wires. The inclined plate 14 is serrated in order to prevent the matrices from rebounding from the stop-pin 15. A pin 69 on the matrix basket engages under a part 68 of the fixed frame to prevent the basket from being raised before it is thrown out of gear. The basket may be moved into and out of gear by hand.
