Abstract: 1483. Gilbert-Stringer, H. J. S. Jan. 22 Type, setting &c.-Relates to a method of, and apparatus for, justifying lines of type. The lines are composed with thick spaces and longer than the justified line, and, to justify the line, the thick spaces are removed, reduced to the proper thickness by passing over an adjustable milling-cutter, and re-inserted in the line. Fig. 1 shows a plan of the machine, and Fig. 12 a sectional view of the type-separating &c. mechanism. The types from any suitable composing-mechanism are delivered through a channel a into an assembly channel or raceway formed between the walls b, c, into which they are fed by the reciprocating pusher d. A line abutment g supports and yields to the advancing types, under pressure of a cord and weight. A collar j on a rod k is engaged by the abutment g when the line is the proper length, and the collar j and rod k are moved by the abutment a distance equal to the excess length of each line. The collar j is adjustable on the rod in accordance with the required length of line. Depression of the space key of the composing-mechanism inserts a thick space in the line, and also feeds a piece m and slide n to the left, one step for each depression of the key. The slide n moves under a series of pairs of wedges o, p, the parts p of which are mounted to slide horizontally in a box 36, and the longer depending parts are movable vertically to spread the series of wedges. The slide n is moved under a number of wedges equal to the number of thick spaces in the line. When the line is composed, the operator depresses a starting-lever s, which through an arm u, rod v, and arm w rocks a shaft x and engages a clutch 5, 8, which locks a pinion 9 to a continuously-rotating shaft 6 driven by a pulley 7. The wheel 9 drives a wheel 10 and series of cams 12, 13, 14, 15. These operate to lock the line between the abutment g and a stop on the rod k, and then to elevate a vertically-sliding frame carrying the slide n, thus pushing up the wedges o under which the slide n has been moved. This expands the wedges and moves a spring-pressed plunger 37 to the left until an arm 38 thereon engages a stop q on the rod k. The advance of the plunger 37 is equal to the excess length of the line, and as the number of wedges elevated is equal to the number of spaces the elevation of each wedge will be proportionate to the excess length divided by the number of spaces. The amount of elevation of the wedges determines the position to which the milling-cutter is set by mechanism connected with the vertically - movable slide which elevates the wedges. The cutter is thus set in position to remove the proper amount from each thick space. The line is then unlocked and the wedges returned to normal position, and the rod k is partially rotated to withdraw the abutment g from in front of the line. The depression of the starting-lever s also engages a clutch 51, 52 connecting a cam barrel 54 with the wheel 10, so as to wind up accord 55, on the barrel, to which a weight is attached. The cam-groove of the cam 54 oscillates a lever 57 and a pivoted head 58 carrying a sliding rod or lever 60 connected to a line carriage 61 sliding in the wall c of the raceway. A finger 63 on the carriage 61 engages behind the line, and the clutch 51, 52 is then disengaged by a cam piece on the wheel 10, and the carriage 60 and line are then urged to the left by the action of the cord 55 and weight. The finger 63 moves the line to the left until the foremost type is stopped by a wall 67, Fig. 12, whereupon a cam piece on the wheel 10 operates to engage a clutch 73, 74 which connects a shaft 76 with a rotating pulley 75. Another cam piece on the wheel 10 then operates to disengage the clutch 5, 8 and stop the wheel 10 and cams 12,13, &c. On the shaft 76 is a cam 82 operating a lever 83 connected by a link 84 with a plunger 85, by which the types are separated and pushed singly, against the pressure of spring-pressed sliding strips 86, to the mouth of a justifying-channel 88. A number of the strips 86 is moved by the type equal to its thickness. A plunger 95, operated by a cam &c., and forked to embrace the strips 86, forces the separated type or space into the channel 88. As each type is brought to the position shown at 96, a reciprocating feeler 100 is moved against that part of the type above the walls of the channel 88. The justifying-spaces being shorter than the other types &c., the feeler passes over each of them, and makes an increased stroke. This operates mechanism by which the cams 82, &c. are stopped, and a space is engaged and moved over the mitting-cutter. The space is engaged by knife-edged gripping-pieces 123,124 on a vertically-movable slide 121, moved down over the cutter and then moved up again into position in the justifying-channel to be advanced by the next type. When the last type of the line has been removed by the plunger 85, the finger 63 passes through a slot in the plunger, and a pin 131 on the carriage 61 engages an arm 132 of a shaft 133 which operates mechanism bv which the clutch 73, 74 is disengaged. The justified lines pass along the raceway 88<1>, the length of which is a multiple of the length of the line, to the galley 152, into which each line is pushed, after the withdrawal of a supporting-rule 153, by a presser-bar 156.
