23,006. Timmis, W. S. Oct. 24. Type - - writers, type setting, monotype, stereotype matrix, linotype, and like machines. - Relates to apparatus for producing perforated or like controlling-strips for typewriting t y p e casting, composing, impressing, or like machines by which justified lines are produced, and especially for the machine described in Specification No. 23,007, A.D. 1903, by which justified lines of characters are printed on lithographic paper. Fig. 1 shows a front elevation of the preferred form of machine, and Fig. 6 shows diagrammatically the electrical connections &c. A type-writer A, of any suitable construction is provided, which prints a letterpress copy of the matter represented by the perforations made in the strip. Under the key levers of the keyboard B of the type-writer are series of vertical rods B2 through openings in which pass wires X, the left-hand end of each wire being fixed, and the right-hand end connected to one of a series of circuit-closing arms D pivoted side by side at D3. The depression of any key lever depresses one or two pins B2 operating one or two arms D. There are 22 arms which make and break the contacts at D, Fig. 6, closing circuits through magnets S, S', J7, J23, &c. which operate the punches L, Fig. 1. The paper strip F6 is fed from a roll F5, between a pair of feed rollers F, one of which is in a spring-pressed arm F3, and the other is operated oy ratchet mechanism actuated by a rod H5 connected to a lever H2, H9 attached to the armature H1 of a magnet H, the circuit of which is closed at each operation of a key. The strip then hangs down in a loop and passes between a pair of feedrollers G', G2, the former of which is fed, one step at each operation of a key, by a special ratchet feed-device operated by a sliding bar G4, operated from one of the magnets S or S1 which operate the punches for making the feed-perforations in the opposite edges of the strip. The strip then passes over the punches L and to the re-winding device. The roll E5 on which the strip is re-wound rests on two rollers E', E4 geared together and driven by ratchet mechanism from the arm H9 operated by the magnet H. A roller E7 rests on the roll E5. The arms D are held in normal open position by springs, and are provided with contacts which, when the keys B are depressed, engage insulated contacts D'‹ connected to the punch-operating magnets. There are 22 punches L, the two outer ones which punch the feed perforations being operated by the magnets S, S1, which are both put in circuit when any key is depressed. Two groups of the punches represent characters, one of these group the thicknesses of the characters, and these two groups also represent space thicknesses for justifying the lines. One of the punches makes a "space-trip" perforation when the space key U is depressed, and another makes a " line-trip " perforation, at the end of each line. This "line-trip" perforation is made with two justifying perforations, one of which indicates the number of units of thickness of space and the other fractions of units required in each word space to justify the line produced in the printing or composing &c. machine. When these two perforations are alone, they represent characters, but when accompanied by the line - trip perforation, they represent space thicknesses and operate the space selecting means. The character &c. punches are operated by the armatures of magnets J17, J23, J25, J27, J29, J31, J33, J35, J39, J41, J43, J45, J47, J49, J51, J53, and J55, Fig. 6, and the space and line-trip punches by the armatures of magnets J61, J71 respectively. The feed-perforation magnets S, S1 are in a circuit J1, J', J3, J4, J5, J6 including the generator J7. The circuit of the magnets S, S' is also closed by a relay J20 which is in the return wire J5 from the ring J18 connected to the punch magnets. This relay closes the circuit from the generator J7 by wire J15, the bar carrying the arms D, wires J14, J2 through the magnets S, S'. The wire J8 leads to the counting-magnet M, and thence by wires J64, J5, J6 to the generator. The wire J56 leads by wire J57 to a magnet N19, and from thence by wires J58, J59, J60 to the space-trip magnet J61. The line-trip magnet J71 is energized by the closing of contacts carried by the type - writer carriage. The magnet M operates a counting - mechanism connected with means for automatically selecting and operating the necessary space-selecting punches for justifying the line. The armature of the magnet M is connected to a slide having a pivoted pawl engaging and moving the units counting wheel M18, Figs. 24 and 1, and the movement of the slide is regulated according to the thicknesses of the characters, by an arrangement of stops operated from the punches representing the thicknesses of the different characters, so that the wheel M is fed a number of units equal to the thicknesses of the characters. The wheel is also fed a distance of three units at each operation of the space key U. A means is provided for cutting the magnet M into circuit only after the punches have been moved, so that the feed slide is not moved until the stops are set. The armature of the magnet S1, when attracted, closes contacts J", J", which close a separate circuit &c. through the magnets H, M. The proper justification punches are selected and operated automatically at each return of the type-writer carriage for a fresh line. For this purpose an arm N, Figs. 1 and 24, is mounted to slide in a guide N4, N5 pivoted on the stud carrying the counting-wheel M18. On the wheel M18 is a pin M100 which engages and moves the arm N during the latter part of the movement of the wheel, and the end of the arm, which carries two contacts N2, N3, is moved over rows of contact pins V99, V100. These pins are arranged in radial rows and in double curved rows. In each double curved row the pins V99 represented by black dots represent the numbers of units in the sizes of spaces, while the other row V100 shown by open circles represents the fractions of units of the spaces. At each operation of the space key the arm N is moved longitudinally to the next circumferential double row of pins, a double row being provided for each different number of spaces required in any line. The arm N is formed with rack teeth gearing with a pinion N9 on a central shaft N" on which is a second pinion gearing with a rack bar moved by ratchet gear actuated by the magnet N19, Fig. 6, which is in a circuit closed at each operation of the space key. In order that the length of lice may be varied, an index disc N99, is provided, held in adjustable position by a stop N97. A pin N95 on the disc N99 limits the return movement of the counting-wheel M18 and locates its zero position, by engaging the pin M100. The pins V99, V100 extend downwards, and all pins representing the same number of space units or fractions, are connected to one of a series of superposed insulated metal plates, projections of which are shown at V1 .... V8 and v1 .... v8, Figs. 6 and 24, and these are connected by wires V11 .... V18 and v11 .... v18, to the circuits of the proper punch magnets. The contacts N2, N3 on the arm N are connected respectively to circuit wires J94, J95 and J75, J96. In these are circuit breakers J97, J98 and J99, J100 closed by the armature of the line trip magnet J71 when the circuit of this magnet is closed at each return of the carriage, so that the punches for justifying are operated at the end of each line together with the line-trip punch. The line-trip magnet is in circuit with an apparatus P, Figs. 1 and 6, on the carriage. This apparatus operates to close the circuits through the space and line-trip magnets, and also momentarily to cut out of circuit the counting-magnet M so that the wheel M18 and arm N may not be moved at this time, and afterwards to close the circuit of a restoring- magnet O, which operates release mechanism to effect the return of the counting-wheel and arm N to normal position for a fresh line. An electric lamp signal Q is provided to indicate to the operator when the line is about full. The circuit of this lamp is closed during the time that the contacts N2, N3 are over any of the pins V99, V100, by means of a contact Q5 on the arm N engaging a contact plate Q6 of the required shape. A special indentation key, for forming a space at the beginning of a line, is provided, which closes the circuit through the magnet M only. In the case of short lines at the ends of paragraphs &c., a special key is provided, which closes the circuits of the spacetrip magnet, feed-hole punching magnets, and the magnets H, M. Sparking at the contacts D is prevented by the arrangement shown in Fig. 7, which comprises a condenser, and contacts, the latter being operated to close and open the circuit just before the contacts D are moved together or apart.
