Abstract: 962. Burden, T., and Martin, E. A. Jan. 13. Appliances for indicating and correcting errors in composed matter; copy-holders. - An appliance for indicating errors in composed matter comprises two line-indicators moved synchronously, one over a proof-sheet and the other over the matter in a galley. The corrections may be made by hand, or, for line - casting machine matter, the galley indicator is replaced by devices for ejecting, inserting, and transposing slugs. Fig. 1 shows an appliance for indicating only. The composed matter is contained in a galley 11 provided with walls 12, 13 on two sides only; the galley is placed on rollers 10 between guides 9, with the end slug against a stop 4. The proof-sheet is held by a clip 37 on a table 19, and is adjusted so that the last line is in register with an adjustable pointer 16. Two line-indicators 65, 34, respectively for the composed matter and the proof-sheet, are traversed synchronously by means of nuts 64, 24, screws 51, 54, and gearing from a handle 50; automatic return is effected by means of a weighted cord 57 on release of a ratchet detent 62. The nut 64 also carries a spring - pressed pivoted clamp 67, which holds the matter behind it towards the stop 4 compact; the galley is free to move forwards on the rollers 10 to provide the requisite looseness for insertions &c. in the matter in front of the clamp. The line-indicator 34 for the proof sheet is carried by a spring- pressed pivoted member 31 bearing upon a pivoted guide - bar 21, which is adjustable by means of a screw 23 to regulate the movement of the line-indicator. In an appliance including slug-manipulating devices, the proof-sheet table is arranged nearly vertically instead of horizontally as shown in Fig. 1, and the galley indicator is replaced by a carriage 94, Figs. 11 and 17, for a slug - box 100 containing the correction slugs, a wedge-shaped spacer-bar 170, a slugejector 118, a slug-depressor 135, a galley clamp 67, and fixed slug-retainers 178, 181. The parts, where necessary, are recessed for the passage of two-line letter slugs. Two handles are provided in connexion with gear sectors 109, 162, respectively, for actuating the slug-ejector 118 and slug-depressor 135 for substituting correction slugs, and the spacer-bar 170 for providing extra space in the galley matter for insertions. The ejector 118 is pivoted to an arm 114 on a rack 113 geared to the sector 109, and is formed with a guide-slot 124 engaged by a friction roller so that the galley slug is raised to clear the adjacent slugs in case of a two-line letter. A follower 108 presses forward the slugs in the box 100 for delivery first into a recess 119 in the ejector and then on the return of the ejector into a second recess 121 at a higher level. A lever 156 falls behind the transferred slug to prevent it from being returned with the ejector; when it is desired to eject a galley slug without substitution, a handle is operated to withdraw the lever 156 through connexions 149, 152, 153, and to move a spring catch 125 behind the slug in the recess 121 of the ejector and into position to prevent the transfer of a slug from the box 100 into the recess 119. The slug-depressor 135 is secured to an arm 134 of a bridge-piece 133 between pivoted arms 131 connected by links 130 to a cross-piece 129, which is advanced by means of a stop 117 on the rack until released by trips 138, springs 137 effecting the return movement. A tumbler 143 co-operates with the bridge-piece 133, first falling into position to hold up the bridge-piece from the time of action of the trips 138 until the rack 113 returns and, through a stop 115 on the arm 114, raises the tumbler into the position shown in Fig. 11, thus allowing the depressor to descend suddenly. The spacerbar 170 is connected to extensions 168 on two racks 167 geared to the sector 162. A slugretainer 176 is carried by an arm 175 on a crosspiece on uprights 171 on the extensions 168; the spacer-bar partly ejects a galley slug and the retainer 176 finally restores this galley slug into position. For transposing, the appliance is set to eject without substitution, and the ejected slug is then placed in the ejector and reinserted in the galley in a space made by the spacer-bar. The slug-box may be provided with an inking- pad and paper roll for taking proofs of the substitute slugs. The slug-box, spacer-bar, &c. may be dispensed with and a plain ejector slide substituted.
