Abstract: 15,547. Lanston Monotype Corporation, [Lanston Monotype Machine Co.]. July 5. Monotype machines; type, setting. - Relates to means for preventing, the delivery to tbe galley of a type making and composing, type-setting, or like machine of a line of types containing errors of composition. The device, which is described as applied to the monotype machine described in Specification No. 8633, A.D. 1899, may be controlled from the record strip by means of a special signal. The transfer bar 273, Fig. 7, which pushes the line into the galley, is provided with a channel 2 which, when the transfer bar is in its advanced position, registers with the line channel 266, so that a defective line is drawn by the line-carrier into the channel 2 and is thus diverted from the galley. The bar 273 is locked in its advanced position by a vertically-movable bolt 6, Fig. 5, which engages the actuating-lever of the bar. The bolt 6 is connected to a lever 12, which is normally depressed by a spring 7<x> and can be connected to and lifted by the lever 299 which actuates the galley blade. The head 17 of the galley blade has a slot which can be engaged by a pin 16 on a rotatable rod 15 which is connected to the lever 12. A pawl 13 locks the lever 12 and bolt 6 in their raised position. The rod 15 may be rotated to connect and disconnect the levers 12, 299 by means of the device described in Specification No. 5957, A.D. 1902 ; this comprises a switch bar 102 pivoted to an arm 101 on the rod 15 and having shoulders 105, 106 adapted to be engaged by an arm 113 on the line-carrier slide. To the bar 102 is pivoted a lever 107 havitig shoulders 108, 109, Fig. 10, which engage the ends of the bar. The lever 107 is connected by a link 112, lever 111, and link 110 to a crest-bead 72, on a shaft 71 which is held in either of two positions by pawls 73, Fig. 6, engaging shoulders 74. The cross-head 72 is shifted from one position to the other by rods 83 pivoted to a lever frame 78. The rods 83 are lifted into the path of the cross-head by plungers 'are controlled by the designating-perforations of the justifying-signal in the record strip. The lever frame 78 is actuated to move the cross-head by a pin 85 on the die-case centring-lever 390 through a notched arm 84 which is raised into engagement with the pin by a plunger actuated by a special perforation in the record strip. When a defective line is to be cut out, a special perforation is associated with each designating-perforation of the justifying-signal. The first special perforation causes the shoulder 106 of the switch bar 102 to be rocked into the path of the arm 113 which, moving to the right, turns the rod 15 so as to connect the levers 12, 299 and effect the lifting of the bolt 6 into operative position. The second perforation causes the lever 107 to be moved into the path of the arm 113 without moving the bar 102. When the arm 113 returns to the left, it strikes the lever 107, turns the shaft 15 so as to disconnect the levers 12, 299, and returns the switch bar 102 to the inoperative position. The rise of the galley blade to permit the next line to enter the galley, trips the pawl 13 and allows the lever 12 and bolt 6 to descend.
