Abstract: 14,388. Lagarde, J. June 25. Type, setting; type-writers ;monotype and like machines. - Relates to machines for producing perforated strips for controlling composing and like machines. On the bed-plate 1 of the machine are uprights 2 carrying a table 3 on which are fixed two electromagnets 4. On the table 3 is a bracket 5, on which is pivoted at 6 a two-armed lever 7 having armatures 21 co-operating with the upper poles of the magnets 4. The coils of the armatures 21 are in circuit with the corresponding electromagnets 4. The lever 7 is connected by rods 10 to levers 11 pivoted at 12 on posts 13 and having toothed segments 14 on their ends, gearing with opposite sides of a pinion 15 on the shaft of a wheel 18. The ends of the lever 7 are formed with hooks 8 and adjusting-screws 9 engaging lever frames 35 pivoted on posts 34. On the outer sides 36 of the lever frames 35 are rows of adjustable screws 37, all of different length, adapted to engage the upper ends of three-armed levers 32 pivoted at 31. Each lever 32 has an armature 33 co-operating with one of the magnets 24, of which there are a number of rows or series. When the circuit of one of the magnets 24 is closed, it attracts its armature 33, and throws the upper end of its lever 32 into the path of the corresponding screw 37, so that the movement of the frame 35 and lever 7 is stopped by such lever 32 and screw 37, and the wheel 18 is set in a corresponding position. One of the magnets 4 is put in circuit when the circuit of any of the magnets 24 is closed, and thus the lever 7 is operated. The circuits of the magnets 24 are closed by any suitable keyboard arrangement, such as that described in Specification No. 14,457, A.D. 1901. The periphery of the wheel 18 has transverse rows of holes or depressions which control the number and position of the holes punched transversely of the strip at each operation. The wheel 18 has a flange 19, the periphery of which is provided with types or characters which print on the edge of the strip the character corresponding to the row of perforations, to facilitate the verification or correction of the matter. Under the wheel 18 are a series of levers 42, the number of which is equal to the number of longitudinal rows of perforations made in the strip. The levers 42 have sockets 47, into which dies or punches 48, on levers 49, are adapted to enter and punch the strip 53. The levers 49 are all lifted simultaneously by a hammer 55 on a lever arm. The hammer 55 has also a projecting part which presses the strip against the types on the flange 19. The types are inked by two spring-pressed inking- rollers. The hammer 55 is lifted by one end of a lever 59, the other end of which is engaged by two arms 60 of levers 61 which project up through the table 3, and are engaged by levers 62 carrying electromagnets 63, which are attracted by the lower poles of the magnets 4. When the levers 49 are lifted, those which engage levers 42 stopped by the wheel 18 punch the strip, but the strip is not punched by the levers 42, the ends of which enter holes or depressions in the wheel. The levers 42 may be formed as punches, and the levers 49 provided with sockets. The strip 53 is fed at each operation by a ratchet mechanism operated by an electromagnet, the circuit of which is broken and closed by a projection on the hammer 55. The perforated strip may also be used for controlling machines used for telegraphic typographic composition.
