22,374. Lanston Monotype Corporation, [Bancroft, J. S., and Indahl, M. C.]. Oct. 21. Type, setting; stereotype-matrix machines; typewriters. - Relates to typographic composing- machines, such as typecasting, composing, writing, matrix-making, &c. which are controlled by a pattern or record strip, and consists in the provision of automatic justifying-mechanism controlled by signals in the pattern representing line deficiency and number of spaces respectively. The device is described as applied to the machine described in Specification No. 8633, A.D. 1899. The linedeficiency signal positions a slide 20 having a straight-edge 26, and the signal representing the number of spaces positions an interponent 22 which slides at right-angles to the slide 20 between the straight-edge 26 and a radius bar 21 which turns about a pivot 27. The radius bar, which is normally parallel with the straight-edge 26, moves into contact with the interponent 22, the amount of its movement being proportional to the amount to be added to each space in order to justify the line. A slide 23 which moves parallel with the slide 20 into contact with the radius bar adjusts the mould-blade accordingly. The slide 20 is adjusted by means of two bars 40, 41 which replace the justifying-wedges of the prior machine. The bars are provided with projections 42 which, when the bars are raised by levers 16, are engaged by one of the pairs of final positioning-jaws 6. Racks on the bars engage pinions on two shafts 47, 48 which, by means of racks and pinions, adjust two wedges 50, 51. The movement of the wedges is transmitted by a bell-crank lever 54 and an adjustable block 56 to the slide 20. The levers 16 are raised by pistons 17 controlled by two designating-perforations in the record strip with each of which is associated a dimensioning-perforation which determines the closed position of the jaws 6 and the amount of movement of the bars 40, 41. The interponent 22 is guided in ways in a shoe 29 sliding on a rod 31. To the shoe is pivoted a bar 65 having a head 66 adapted to be interposed between the jaws 6 of the other positioning mechanism. The bar 65 is moved into operative position by a sliding cam-bar 69 operated by one of the designating - perforations which control the bars 40, 41. With the designating- perforation is associated a dimensioning-perforation which determines the closed position of the jaws 6 and hence the position of the interponent 22. If more than fourteen positions of adjustment for the interponent are necessary, a second bar 65 is employed, the head 66 of which is displaced from that of the first bar by an amount equal to half the distance between consecutive pins of the primary gauge. One bar 65 then represents even and the other odd numbers of spaces. The slide 23, which adjusts the mould blade, is provided with a rack gearing with a pinion on a shaft 85 which can move longitudinally and has at one end a screw engaging a thread in a fixed block 87. The end of the shaft bears against a block 88 connected by parallel links or otherwise with the block 87, and serving as an abutment for the mould blade. The slide 23 is caused to move the radius bar 21 into contact with the interponent 22 by a spring surrounding the shaft 85. Specifications No. 18,638, A.D. 1899, and No. 27,278, A.D. 1904, are also referred to.
