258,447. Leysieffer, R. Nov. 24, 1925. Index type-bar mach ines; aligning for impres sion.-In type-bar ma. chines of the kind wherein slidable type-bars carry ing numerical &c. char acters on their undersides are set by means of a stylus or the like, a series of type-bars is provided each having a complete alphabet and a set of numerals and symbols to adapt the machine for printing on cheques. mercantile forms, &c. Type-bars bearing complete words or statements may also be provided. The type-bars 4, Fig. 1, are of I-section and are slidable between guide bars 5 in a 'frame 2 pivotally mounted above a desk-shaped casing 1 upon which the paper is placed. The upper faces of the type-bars are provided with indentations to receive the stylus, the indentations being marked to correspond with the type characters on the underfaces. Similar characters may be inscribed between the slots of a grid-like plate 12 covering the type-bars, the setting of which is effected by inserting the stylus within the slots and sliding the type-bars until the stylus comes against the edge 13 of a covering plate 10. The plate 12 is slidable rearwardly to enable a set line of type to be examined before printing. Spring-pressed pivoted pawls 14, 15 bearing upon serrations in the type-bars hold them in their set position. After printing, the type-bars are restored to their original position by a slidable returning-bar 20 with outwardly projecting handles. To enable certain type-bars, such as those for printing the date &c., to remain stationary, the bar 20 is recessed to over-ride them. The printing-frame 2 is lifted by swinging rearwardly a hand-lever 26 on a shaft 25, and is lowered on the return of the lever. Line-spacing mechanism.-The paper blank or form is placed upon pins 28, Fig. 10, on a bar 29 slidable upon the surface of the casing 1 under the action of the lever 26 to align any line of the paper in a position to receive the impression of the set of line of type, means being provided to disengage the bar 29 automatically and retain it in the requisite, position. The bar 29 is displaced by rack bars 41 disposed along each side of the casing and provided with lateral stops 42 adapted to bear against arms 43 pivoted on the bar 29, so that when the racks 41 are displaced longitudinally by a gear train 40 driven by a sector 39 on the lever shaft 25, they move the bar 29 with them until a roller 44 on each arm 43 slips within a recess 45 in a rack bar 36, allowing the arms 43 to slip from the stops 42 bearing against them. The rack bar 36 is set in the requisite position by a pinion 35 on a shaft 34 carrying a pinion which engages internal teeth in a graduated setting member 31. The rack bars 36 are notched to engage spring-pressed pins 37 which hold them in their set position. The bar 29 is moved to align the paper by the same furward movement of the lever 26 which lowers the type-bar frame 2 upon the paper, and the bar is returned to its datum position by stops 46 on the rack bars 41 engaging it when the lover 26 is swung rearwardly to raise the frame 2 for the removal of the paper. Roller-impression arrangements. - In its set position, the line of the paper to be printed upon is disposed above a slot 47, Fig. 5, in the casing 1, and above a resilient roller 48 projecting there. through. The roller 48 is journaled upon a carriage 49 which slides along a guide bar 50 mounted below the slot 47, the driving means comprising an endless chain 53 driven by a sprocket wheel 51 at one end of a shaft carrying a pinion 54 in engagement with a quadrant 55 on a hand-lever 57. An adjustable inking-ribbon is disposed between the line of type and the printing-roller, and by this means a number of copies may be taken. A rod 58 pivoted upon the lever 57 is reduced at one end 59 which passes through a bush 60 pivoted upon the lever 26, the collar formed by the increasing diameter of the rod being so disposed that it abuts against the bush 60 on the return of the lever 26 thus restoring the lever 57 and the roller carriage 49 to their original positions. Paper-feeding arrangements. - The printed sheet is ejected laterally from the machine by sets of co-operating rollers 62, 63, Fig. 12; the rollers 62 are mounted on pivoted arms 64 and normally held away from the paper by a spring 65, and the rollers 63 are driven by a gear train 67-69 and a toothed sector 39 on the shaft 25 of the handlever 26. The arms 64 are connected to a lever which is rotated against spring tension to move the rollers 62 into the position indicated by dotted lines in Fig. 12, whereby the sheet is then disposed between the rollers 62, 63 and is ejected by the rotation of the latter consequent upon the rocking of the lever 26, this movement also raising the type-bar frame 2 upon its pivot. A clutch 71 ensures a one-way rotation of the rollers 63.
