Abstract: 4524. Voget, P. A. Feb. 23. Type-writers.-In a stenographic type-writer or machine for taking down the spoken words, the letters may be printed above, on, or below the line and in various colours, in order to indicate vowels, cases of nouns, tenses of verbs, and the like. The paper roller is replaced by a lever 41 mounted on a pivot 6, and provided with arms 12, 13. These arms are connected by rods 42, 43 with two keylevers provided with keys 15, 16. The lever 41 can thus be given a rocking motion which is shared by a strip of paper passing from between two feed-rollers over the cylindrical surface of the lever 41, on which it is held by small hooks. The type-bars 54 are operated by keys 5 on levers 87. The inking-ribbons 47, 48, 49, 50, are supported by metal holders attached to arms 59, each of which is supported by a pair of a levers 60. A projection on one lever of each pair is connected by a rod 63 with one of the keys 64, 65, 66, 67, whereby the various ribbons are brought over the lever 41. Each of these ribbon key-levers is in the form of a rectangular frame consisting of two levers pivoted on an axle on opposite sides of the machine, and connected by a rod which carries the key. The paper strip winds off a roller, passes tween rollers 44, 45 and over the lever 41. The spacing-mechanism consists of two levers 81, on opposite sides of the machine, connected in front by a bar which carries the spacing-key. A bar connecting the two levers is depressed by each of the typelevers 87 as they are operated. The end of the lever 81, beyond the pivot, is slotted and engages a pin on the end of a second pivoted lever 91, Fig. 10. The further end of this lever is pulled upward by a spring 92, and is connected by a rod 94 with a pivoted lever 97, carrying a pawl 95, which actuates a ratchet-wheel 98 attached to the paper feed-roller 44. The ratchet-wheel is advanced one tooth for every depression of the space key, or of any of the type-keys 5. The roller 44 is of ebonite, or the like, with grooves on its circumference, and rotates a rubber roller 45 by friction, the motion of the roller 44 being thus transmitted to the paper strip. The ink ribbons are also shifted after each impression. The ribbon is wound on a metal roller 101, Fig. 11, to which is fixed a ratchet-wheel 102, provided with a spring pawl 104 pivoted to a lever 103. A finger 105 on this lever presses on a lever 107, working on a pivot 106 and capable of being lifted by a lever 108, which is integral with the lever 60, Fig. 1. Thus, on striking the key 65, the ribbon 50 is moved over the lever 41 and, at the same time, the ribbon roller is rotated through the space of a tooth. To enable the ribbon keys to be depressed at the same time as the type-keys 5, the latter are pivoted at 111, Fig. 7, to the keylevers. Springs 113 tend to pull them out of the vertical, but they are retained by fingers 114. If the key is depressed in an inclined direction, a projection 116 engages a projection 117 on the key-lever 64, and the latter is also operated. In Fig. 8, the key-rod has two projections 116, 118 whereby it may engage either of two ribbon keylevers 64, 65.
