Abstract: 22,553. Lanston Monotype Corporation, [Lanston Monotype Machine Co.]. Oct. 12. Type, setting ; type writers &c. -Relates to machines of the kind described in Specifications Nos. 8634 and 18,638 A.D. 1899, for producing record strips or controllers for automatic type casting, setting, writing, and like machines. The machine is provided with means for automatically selecting the justifying-signals which are made by the depression of a single key. Means is provided for preventing the operation of the justifying-mechanism until the line has reached a certain length, and for preventing the inclusion in the line of a character for which there is insufficient room. Perforations representing leading and sectional line justification are made by special keys, and a repeat key enables any signal to be repeated, or marginal feed-perforations to be made in advance of the line. The punch-bars 1 as heretofore have lugs engaging slots in an actuator 3, with which they may be connected by interponents 7 advanced by keys 8. The units' wheel 16, Fig. 12, is carried by a shaft 25 which is rotated by a rack 29 connected to pistons moving in air-cylinders. The units' rack carrier 18 and pawl 17 are actuated by rocking cams connected to the punch-actuator 3. In addition to the ordinary line scale 33, a pointer moving over a dial and geared to the units' wheel is provided to indicate fractions of the unit. The justification-signal selecting-mechanism comprises a proportional divider mechanism which divides the unoccupied space in the line by the number of word-spaces and selects the appropriate punches. The proportional divider comprises a lever 64, Fig. 18, having a movable pivot carried by a sliding block 66 which is adjusted in accordance with the number of word-spaces in the line. The pivot is journaled in a block 51 sliding on a fixed bar 50. The upper end of the lever 64 is pivoted to a slide 46, the movement of which selects the justifying- punches, and the lower end of the lever passes through a slide 48 which is moved by a lever 58 having an adjustable pivot block 59 The upper end of the lever 58 is pivoted to a slide 45, which is connected to the line-measuring mechanism and moves through a distance equal to the amount of space to be filled by justification. The block 59 is adjustable by means of bars 52 to adapt the mechanism for different founts. The block 66 is pivoted to a block 71 sliding on a lever 69 which is connected to and moved by a block 47 sliding on a bar 43. The block 47 is advanced a step for every word-space, and the pivot-block 66 of the lever 64 is thereby adjusted so that the travel of the slide 46 is reduced to a half, a third, a quarter &c. of the full amount. The levers 58, 64 normally rest parallel with the bars 50, 52, the slides 45, 46 being in contact with adjustable abutments 77. The slide 45 is connected by a rack 94 and pinion with a disk 103, Fig. 12, loosely mounted on the shaft 25 of the units' wheel. The disk may be advanced by a lever 106 to bring a pin 104 on its surface into the path of a pin 105 on the units' wheel. Upon the depression of the justifying- key at the end of the line, the disk 103 is advanced and rotated by the rack 94 until arrested by the contact of the pins 104, 105. The slide 45 is thereby moved through a distance proportional to the amount of unoccupied space in the line. By means of the screws 77, the units' wheel may be set back beyond the zero point for different founts, the amount being indicated by a pointer and dial. Justification-punch selecting-mechanism. To the punch actuator 3 is secured a second actuator 120, Fig. 1, which is engaged by lugs on the dimensioning series of punch-bars and on two special designating-punches. With the actuator 120 co-operate two pairs of interponents 122, 123 and 124, 125, Fig. 27. The interponents 122,124, when advanced, cause the actuation of the designating-punches, and the interponents 123, 125, which are movable laterally by the slide 46 of the proportional divider, select the proper dimensioning-punches for each signal. The slide 46 actuates a rack 142 geared to a rack-bar 139, Fig. 27, which moves the dimensioning-interponent 125 of the first or major justification signal. The rack 142 also rotates a pinion 154, to which are secured pawls 155, 156, Figs. 32 and 33, co - operating with fixed and movable ratchets 153, 154, respectively. The teeth of the ratchets are in the ratio of -one to fifteen, which is the relation between the major and minor justifying-units. During the advance of the slide 46 and rack 142, the pawls slide over the teeth of the ratchets, but on the return movement, the pawl 156 drives the ratchet 154 until arrested by the engagement of the pawl 155 with a.tooth of the fixed ratchet 153. The ratchet 154 is connected with a rack-bar 140, Fig. 27, which moves the dimensioning- interponent 123 of the second or minor justification signal.' Both interponents 123, 125 are thus adjusted during the return of the slide 46, and are, with their designating-interponents, successively moved into engagement with the actuator 120 upon the depression of the justifying-key. Leading and sectional line justification. A leading-signal may be formed in conjunction with either justifying-signal by means of two interponents which can be coupled with the justifying- interponents by the operation of special keys. The line-closing signal for sectional justification is produced by a special interponent which also causes the simultaneous formation of both justifying-signals. Means for preventing the formation of short lines. Depression of the justifying-key actuates a starting-bar 182, Fig. 42, movement of which is normally prevented by a lever 181 which engages a notch in the bar. A rack-bar 168 is engaged by and advances with the units' wheel when the line reaches a certain length. When the line is long enough to be justified, the rack-bar 168 meets and advances a slide 183, which is connected by a lever 180 with the lever 181. The bar 182 and the justifying-key are thereby released. The pivot of the lever 180 is advanced a step for each word-space in the line so as to increase the justification area, the movement being, however, limited to a certain number of steps. Preventing the formation of long lines. The dimensioning punch-bars are successively locked in the order of the sizes they represent by latches 193, Fig. 42, which are successively released by a block 194 actuated by a lever 196 from the rack-bar 168. The justifying-interponents are successively advanced at the end of a line by levers 137, 138, Fig. 1, which are actuated by pawls 222 engaged by a toothed block 226. The block is advanced in steps by a piston and cylinder, to which air is admitted upon the depression of the justifying-key. Each advance of the block 226 actuates the valve of the actuator motor, and the rise of the actuator successively trips the pawls 222. The final advance of the block 226 operates a valve which controls the resetting-devices of the linemeasuring mechanism. The depression of the justifying-key actuates through the bar 182 an arrangement of valves whereby (1) the proportional divider is advanced and retracted to select the justifying-punches, and (2) the block 226 is advanced to make the justifying-signals and re-set the line-measuring devices. Repeat key. By depression of a special key, an arm 271, Fig. 51, projecting through a slot in the actuator 3, is caused to rock an arm 273 which acts through a rod 225 on the retaining-latch of the actuator-valve. The rise of the actuator 3 permits the arm 273 to return and the valve to be re-engaged by the latch. If the key is held depressed, the arm 273 is again moved upon the descent of the actuator, which therefore reciprocates continuously. Any signal may thus be repeated, or marginal feed-perforations, which are made by punches permanently connected with the actuator, may be formed in advance of the line. Specifications Nos. 5957. 8736, and 8737, A.D. 1902, and No. 21,013, A.D. 1907, are referred to.
