Abstract: 317,915. Marks, E. C. R., (Elliott-Fisher Co.). May 29, 1928. Ink - ribbon mechanism. - A flatplaten typewriter or like machine for manifolding on a multi-ply web or a pair arranged side-by-side is equipped with alternative carbon-arrangements comprising (1) transversely movable carbon webs carried by rolls at the sides of the platen frame and passing over guides thereon, and (2) carbon sheets mounted on a carriage which can be moved longitudinally to bring new parts of the carbon sheets into use and is provided with guides for the multi-ply web and means for slitting longitudinally a fanfold multi-ply web. In the arrangement shown in Figs. 7 and 9, carbon webs 54 interleaved with a multi-ply web a passing longitudinally over a flat platen 14, are wound on spools 52 at the sides of the platen .frame 1 which is provided with slots 61 and plates 62 for guiding the carbon webs. The spools are mounted on shafts 49 provided with knobs 60 and having square parts for engaging the spools. The spools have flanges 55, and clips 53 for securing the carbon webs. Each shaft is mounted in bearings 50, 51, the bearing 50 having a spring latch 57 which engages a groove in the shaft and serves as a retainer and brake, additional braking being effected by tightening the bearing 51 by means of a screw 59. The bearings 51 are pivoted horizontally so that the shafts can be raised above the bearings 50 to facilitate detachment. The carbon webs may be employed with a multi-ply web, or a pair arranged side-by-side, consisting of a number of webs delivered from separate rolls, or folded in a zig-zag pile; or, when the slitting-means described below are used, the carbon webs may be employed with a fanfold multi-ply web. In some cases, for instance when parts of the carbon webs are cut out to prevent complete manifolding of the original, one spool only is employed and the carbon webs are secured at the opposite side of the platen by a clamp preferably consisting of a spring strip 64, Fig. 7, pivoted at one end and detachably retained at the other end by a slotted bracket 65, the bottom edge of the strip being serrated to form a cutter. A carbon-sheet carriage 78, Figs. 4 and 18, can slide on rods 77 secured to the frame 1 and engaging slots 81 in flanges 79, 80 on the carriage. Stepped blocks 82, secured by screws to the carriage, support fingers 83 to which the carbon sheets are attached by means of grooved clamps 84. To permit adjustment of the blocks 82, the carriage is formed with duplicate sets of holes 88 for the block-securing screws. The fingers 63 may each rest at both ends on corresponding steps of the blocks and be secured by pins 85 which pass through a hole and slot at the ends of the finger and into holes 86 in the steps. The clamps 84 are pivoted on the pins 85. When webs having more plies than the number of steps are employed, two fingers 83 are, as shown in Fig. 4, mounted on each pair of steps. When unslitted fanfold webs are employed, the fingers 83 are supported at one end only, and each finger is provided with two pins for engaging holes 83<c> in the steps. Long carbon sheets are employed and the carriage 78 is periodically moved forwards to bring new parts of the carbon sheets into use, the used parts being torn off. Movement of the carriage is limited by a stop 108, Fig. 25, formed on a block 104 which is adjustable on a rack 105 on the frame 1 and is secured by a latch 106, a pointer 107 on the block being arranged over a scale. Paper-supports; sheet and web clamping, guiding, and cutting arrangements;-For guiding a multi-ply web over a flat platen 14, Fig. 7, the above-described carbon-sheet carriage 78, Figs. 4 and 18, is provided with a pair of adjustable guides 89 having top and bottom flanges 91, 92. The guides have lugs engaging slots 94<a> in the flange 80 on the carriage, and are secured by screws 94 which pass through slots in the guides and into holes 94b in the flange. To permit of substantial adjustment of the guides, the flange is formed with duplicate holes and slots. For slitting longitudinally a fanfold web, the carriage is provided at each side with a superposed set of slitting-bars 96<a> secured to spaced plates 96<a> mounted on posts 97 on a laterally adjustable base 100 and secured by nuts 99. The bases have studs which pass through slots 102 in the carriage and are secured by nuts. To permit of substantial adjustment of the bases, duplicate sets of slots are provided. The platen is associated with the paper-clamps 17, 20, 25, web-smoothing device 67, and transverse cutting-edge 26 included in the subject-matter of Specification 317,705, pedal mechanism being provided for successively raising the clamps 25, 20, and depressing the platen at the rear to release the clamps 17. Platen indicators.-The line of transverse cutting of the web is indicated by means of the adjustable fingers 44, Fig. 7, included in the subject matter of Specification 317,705.
