Abstract: 27,582. Ennisson, W. J. Aug. 3, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Drawings to Specification. Type, setting.-Relates to justifying- mechanism such as is described in Specification No. 12,960, A.D. 1897. The words and lines of composed types are separated by separators having projecting ends, and the lines are separated from the continuous line issuing from the composing- machine by any suitable mechanism, such as that described in the above Specification. The line is pushed into the vertical line channel until it and its underlying separator is engaged by a pawl and there held until it is carried up by the lineelevating mechanism. This consists of two slides having pawls for engaging under the line, and a connecting-rod by which they are caused to move up together during a part of the upward movement of the lower slide. The line of types is first engaged by the lower slide and carried up to a waiting position, in which the slides remain at rest until the line shaft commences its revolution, when the line is carried up to the measuring-mechanism by this lower slide The lower slide then moves to its lowest position for a fresh line, and the two slides then move up together, the upper slide carrying the measured line up to the spacer-inserting mechanism and the lower slide carrying the fresh line up to the waiting position. The line shaft then stops until again set in motion to make a complete revolution. The line is measured by means of a pawl on a slide pivoted to one end of a measuring-lever, which moves the line up until its upper end is engaged by the stepped block which limits the upward movement of the line and eliminates the space occupied by the separators in the line. The stepped block is moved into position according to the number of spaces in the line by mechanism controlled by the projecting ends of the separators operating as the line is moved upwardly. The opposite end of the measuring- lever is connected to the means for setting the stepped racks by which the spacer-selecting mechanism is set. The fulcrum of the measuring- lever is mounted to slide, and is moved so that the movement of the measuring-end of the lever varies according to the number of spaces in the line. The fulcrum is set by means of sliding stepped quills or sleeves on a shaft rotated to bring the required steps into position by mechanism controlled by a stop block moved by the operation of the projecting ends of the separators. The end of the measuring- lever engages and moves a vertically-sliding stop into position to stop the stepped selector setting- racks in the required position. This stop has preferably an inclined face or faces engaged by the inclined sides or faces of a projection from the slide carrying the setting-racks. The two setting- racks are placed side by side, and are attached or move together. One of them has several series of steps which operate to set the selector for the insertion of one size or combination of spacers in all the spaces of a line. The other, called the selector-correcting rack, has finer steps, and operates to vary the position of the selector during the justification so as to insert a larger space at intervals when the total amount or number of space units required to justify a line is not equally divisible by the number of spaces in that line. The spacers used are of four sizes, the smallest being called the A or basic spacer and the others B, C, D or fractional spacers, and the arrangement is such that any one of the four spacers may be inserted singly, or two, three, or four A spacers, or any one of the B, C, or D spacers in combination with one or two of the A spacers. The spacers are in vertical channels, from the lower ends of which they are ejected by sliding plungers. The table or support forming the bottom of the channel containing the A spacers is mounted to slide vertically, and may be raised into a position to close the channel and prevent the ejection of any A spacers, or lowered to permit of the ejection of one or more of such A spacers. The table is supported by a stop pivoted to a vertically-movable slide controlled in position by a stepped extension of the setting-rack. The upper end of the stop is also stepped so that, by moving it on its pivot, one of two lower steps is brought under the table, and the latter is lowered to permit of the ejection of one or two additional A spacers. The B, C, and D spacers are each ejected singly, when required, by their plungers on to a table or raceway from which they are pushed laterally on to the ejected A spacer or spacers (if any), and the spacer or combination of spacers held in position by a spring presser-foot is then pushed endways into the space under the word then lifted by the word-lifting mechanism. The words are lifted singly and in succession from the measured line into position for the insertion of the spacers, by a word-lifting slide having pawls or grabs which engage the ends of the separators. The spacers as they are inserted eject the separator which is under the word last lifted. The word-lifting slide is operated from a reciprocating carriage forming part of the spaceinserting mechanism and referred to below. The plungers for ejecting the B, C, and D spacers are operated by bell-crank levers pivoted to the framing. The ends of the shorter arms of these levers are arranged in a vertical line or series, and also in this line, one above and one below it, are two spurs or projections on a slide connected by a rod to the pivoted stop of the A spacer table. The lower spur of the slide is shorter than the upper spur, the shorter spur, when operated, moving the table stop to effect the ejection of one additional A spacer, and the longer spur moving the table to effect the ejection of two additional A spacers. This vertical row of lever ends and spurs is in position to be operated by a series of five pivoted fingers on the reciprocating carriage which is driven by a crank on a continuously-rotating word shaft. The fingers are normally held out of operative position, so that they move clear of the levers and spurs, and the required finger is moved into operative position by a projection on the selector as the carriage moves past it. The selector is a vertical slide set or stopped in position for each line by a foot on the slide engaging the step on the selector setting-rack which is brought under it. The finger-operating projection is formed on a slide which slides vertically on the selector slide, and this sliding part is operated by mechanism controlled by the correcting-rack, the steps of this rack setting a slide forming part of such mechanism in position to be operated by one of a series of cams on the reciprocating carriage. This moves the selector projection so that it operates the next higher finger at intervals, thereby effecting the ejection of the next larger or additional space at intervals when necessary to properly justify the line. The line shift from which the measuring and selector setting &c. mechanisms are operated is driven through one revolution at each operation by a clutch from the driving-shaft. This clutch is released to commence the revolution of the line shaft, at a suitable time in advance of the completion of the line being justified, by governor mechanism driven through ratchet &c. mechanism by worm gear from the word shaft. The word shaft is geared to the driving-shaft. The governor mechanism includes a spiral stepped disc which is released and set for each line. When released it is rotated by a cord and weight until stopped in a position depending upon the number of separators in the line, by a stop set by a slide moved a distance varying with the number of separators in the line. The stepped controller disc, having been set, is rotated through ratchet mechanism by the governor shaft after the line has been measured and transferred to the justifying-mechanism. The disc is thus rotated through one of its steps for each word lifted by the word mechanism, and when it reaches the releasing position it operates to stop further operation of the space-inserting mechanism, and also to release the line shaft driving-clutch by withdrawing a sliding clutch pin which disengages the clutch and stops the line shaft at the end of each of its rotations. The machine operates continuously, many of the parts being set so as to remain in operative position during the justification of a line, while their mechanisms return to initial positions for dealing with a fresh line. The justified lines may be placed in a galley by any suitable means.
