Abstract: 9288. Des Jardins, B. M. May 19. Type, setting.-Relates to apparatus for justifying lines of type which are set up with temporary separators, shown in Fig. 32, between the words Fig. 1 shows a front elevation of the machine, as applied to a Thorne type-setting machine, Fig. 5 the form of separator introduced between the composed lines, and Fig. 27 a right-hand side view of the space-inserting mechanism. As the lines are composed the word separators 152, Fig. 32, are inserted between words, and the number of separators in each line is counted by one of a series of sliding racks 130 mounted to slide vertically in a cylinder 131. The rack 130 is moved down one tooth at each operation of the space key of the setting-machine, and after the setting of a line the cylinder 131 makes a partial rotation, to bring the set rack into position for setting a counting-bar 117 of a space measuring and selecting mechanism contained in the casing B. Each rack 130 is released and returned to normal position after use by a spring. The line of types is packed into a vertical channel 121 provided with a pivoted cover 173, and each line is pushed up through this channel into a measuring and transferring channel 182. The line elevator consists of a block 200 having prongs 203 entering slots in the side of the channel 121. The block 200 is fixed on a reciprocating rod 206. The grooves 168 in the line separators, Fig. 5, enable the prongs to clear such separator at the bottom of the line and engage the bottom type. The separator 150 at the upper end of the line is removed by a pivoted block 212, which engages the separator and is pushed sideways of the upper end of the channel 121 by the channel 182 when it swings over the channel 121 to receive the line. The channel 182 is carried by an arm 176 on an inclined pivot shaft 178, which is rocked to bring the channel 182 in vertical position over the channel 121, and then to swing the channel 182, with the measured line therein, over a platform 170 to the space-inserting mechanism, which also removes the temporary separators. Sliding on the channel 182 is a slide 214, which is pushed up by the ascending type, and engages the projection 120 of a bar 119" rigidly connected at 119<b> to a measuring-bar 119 of the measuring- mechanism in the casing B. The bars 117 and 119 slide vertically in the casing B, and operate to set the mechanism by which the proper combinations of spaces are selected and substituted for the separators in the line. The bar 119 is provided with a horizontal bar or arm which is set to different heights varying with the different lengths of the unjustified lines, and the bar 117 sets a pivoted bar to various inclined positions according to the number of spaces in the lines. A slide which moves on the horizontal arm of the bar 119 is stopped in position by engaging in the angle formed by the horizontal and the inclined bars, and the position of this slide controls the position of a space-selecting rack 452, which determines the combinations of spaces. In cases where a particular combination of spaces inserted in each word-space in the line would not properly justify the line, a wedge and arrangement of escapements &c., forming part of the measuring-mechanism in the casing B, operate to re-set the rack 452 after a certain number of combinations has been inserted, to reduce by a unit the size of the combinations inserted in the remaining word-spaces. The channel 182 swings with the line therein into the position shown in Fig. 27, over a slot in the platform 170. The first word of the line is pushed down through the slot into the cut-off channel 521, carried by a horizontal slide 523 moving in guides 520. The remaining words are prevented from passing through the slot by the word separator, which is longer than the types and the slot. The spacers are contained in the channels 123 of a space reservoir 169, and the required number of spaces to be ejected from each channel is determined by the position of the rack 452, in which are series of recesses 455 which operate to set slides 400, one under each spacer channel. The height of the slides 400 determines the number of spacers ejected from each channel at each operation. The spacers are ejected endways from the reservoir by blades on an ejector slide 409, and they pass into slots 470, in four superposed plates 465 mounted in a slide 431. As the carriage 431 moves forward with the ejected spaces, the plates 465 are also independently moved to varying extents by a pin 466 on an arm 467 working in cam slots in the plates. The slots 470 of the plates are thus brought one over the other, and the whole of the ejected spaces are collected one above another for insertion above the word last pushed down into the channel 521. The slide 523 and channel move to the right of Fig. 27, to receive the spaces from the superposed slots in the plates 465. The spaces are pushed down into the channel 521 by a space clamp 474 mounted on a bracket 475 on the upper plate 465 and suitably operated. The channel 521 now moves back to the slot in the platform 170, to receive another word from the channel 182, the operation being repeated for every space in the line. The word separators enter a slot in an extension of the lower plate 465, and are carried forward successively to a suitable receptacle. The types are fed down from the channel 182 to the channel 521 by a spring ratchet piece 504 on a reciprocated rod 500, which engages a hook on the slide 214. The types are supported in the channel 521 by a friction slide 201. When the channel 521 has received the justified line, it moves to the mouth of the galley b. The side of the channel 521 is now moved back out of the way, together with a rule 538 closing the mouth of the galley, and the line is pushed into the galley by a further movement of the remaining side of the channel 521. The rule 538 is provided with a shoulder for transferring leads or rules from the receptacle 570, at the back of the galley, into place in the galley between the lines. The leading arrangement may be rendered inoperative by a sliding plate on the rule 538. The various parts of the apparatus are mainly operated by cams on two sleeves 600, 700 driven at the proper times by suitably-controlled clutch mechanism from a shaft 610. The driving and clutch &c. mechanisms and the details of the measuring-mechanism are fully described in the Specification and drawings.
