Be it known that i, Pnirnn ALEXANDEI'L VOGET, a subject of the- Merino-11,}; in erio residing at Hanover, in the Empire of C many, have invented certain 119" 2'L1l1i useful Improvements in Sliortiinnd ri-Writing Machines, of which the following a li cation.

The present invention relates to 2L short hand type-writing, mscliinc--thst is to say, 2. machine which is shle to Wrie with smilicicnt speed for taking l'own the spoken Words. For this purpose thi operation oi r the keys does not. ir-mince stra ght lines of positions and that rililwns with nlis ol a printed, letters of uniform color, but letters printed in vziriouscolors above, helm or on the llOlll'lil-l. line. To allow of dom th s, the

A principal feature of this invention con,-

Thus the essential i=1 tors ma-i1 of the Words to nia'ie are indicated by the; depression of mo iCBYS-IllMDBl those corre-- spending to the letters in and k. The preposition to and the final letter e can be omitted. it the 'Euie is adopted that the infinitive form of verb is expressed by printing tlie'veri; in blue ink. Another rule oi this shorthand sjste'in would be that the, root or 'e'sscntial part of a verb printed in red ii the future tense is to be egpresserhin black ii the past tense is to he expressed, and

in green'if the present tense is to be expressed. two keys which print the ietters in k need he oper ed. to Write either of the phrases he wilimwke," he made, or he ins-hes. lit mil he understood that Witl this system the .-+ing can he performed with exce stions speed, especially it special system of stone-typography is adopted w ,ich allows of using "further 30111- hinations of colors and high and low positions of letters. Further description of :t of this kind is, however, not necessary for the explanation of thv new machine.

In the annexed orawings, Figure 1 is a. vcrticsi longituiiinal through the center of the machine seen from the lefthand side. Figs. 52, 3, and 4 represent detziiis of Fig. i in other "tor" ing positions; Fig. 5 is a plan view with part-s omitted.

As wiil he see T0111 the drswings, a iight platen-lever 41 used in the machine instead of thousuzil heavypsper saift rollers, the said lever being mounted on fixed. pivots (5 and provided with two arms 12 1:3, extending in opposite directions. The said arms are pivotslly connected, by means of rods 42 43, with two key-levers which are pivoted at 18 and have at their ends l5 and 16, respectively, so that by alternately depressing thesekeys the lever C he iven e rocking movement in wnich stzip of wsper 46 takes part, passing between H e l'eeo-rolie:rs 44 45, Figs. 3, anal ove cyiinririosi surface of the lever 21'. F0 ii ".iibi201l$ 412 4Q man be separately nio'voii to the nosition 49, Fig. Lin inrinuer which Wili he do scribed hereinafter.

5 5 5 are the ordinary letter-keys, by the depression of which .e lcey-iovers 87 con be rocked on the fixed axle 53. in order to bring the type into con tact with the paper strip 56. For this purpose each key-iever 87 1S pivotnily connected, by means of a rod 52,

with it type-lever 54,1nounted on station- .i'iccording to these rules oniy the means of the key 64.

of the ink on the ribbon 49. The lever 41 is provided with small metal hooks or fingers 57, which hold the paper strip 46 on the cylindrical surface of the said lever, but do not grip the aper.

At 6-8011 side of the lever 41, but not directly adjacent thereto, is arranged the pair or feed-rollers 44. 45, already mentioned, Figs. 7, 8, which serve to move the paper af ter the operation of a type-key or of the space-key. Since the pair of feed-rollers 44 45 on the left-hand side of the machine is considerably removed from that on the righthand side of the machine, it is possible to move the taper strip to and fro by rocking the lever 41 through a small angle, so thatthe point 56, at which the type strikes the pape is sometimes above and sometimes be low. the normal line of writing. As already mentioned, the lever 41 is operated by striking one of the keys 15 16, of which only one--- namely, 16is visiblein Fig. 1, the other, 15,-

being exactly behind it. The ink-ribbons 47 48 49 50 are loosely supported near the striking-point 56 by metal holders 58, which are fixed to parallel arms 59, supported by links 60 and levers 60. The links 60 are mounted on fixed axes 61., and the levers 60, which are integral with arms 62, are mounted on fixed axes 61 and are ada ted to be operated l; y.means of rods 63 an keys 64 65 66 67. In .the position shown in Fig. l the ink-ribbon 49 has been moved into the working position 49 by the depression of the key' 64. The position of rest of the same inleribbon is shown in Fig. 4, in which the inkribbon 50 is shown in its working position,into which it has been moved from its position of rest by The inl ribb on 48 (shown in Fig. 1 in its position of rest) -.=s.

moved into the working position 48 (shown in Fig. 2) by means of the key 67, Fig. 5, and the ink-ribbon 47, which is shownin Fig. 1 in its position of rest, is moved into its work ing position 47, .ig. 3, by means of the key 66. The key-lever 66 is rotatable about the axle 68, the k ey-lever 67 about the axle 69, the key-iever 65 about the axle 70, and the hey lcver 64 about the axle 71. All these key-levers form )ortions of frames, shown in Fig. I). The hey 64, for instance, is fixed to the left-hand front corner of the rectangle formed by the two lovers "2 73, the frame part 74, and the axle 71. The latter is supported in bearings 74 in the lateral metal walls 75 oi the machinc-frame. The keys 6.3 66 67 are rigidl f connected to the respective axles in a siini ar manner.

The paper strip 46 on which the letters are to be printed is wound on a roller, (not shown in the drawings,) this roller being situated on the left-hand side of the machine. From. the said roller the paper passes between the rollers 44 (shown in Figs. 7, 8,) then over the lever 41, Fig. 9, and into a large box or bastype-keys 5, so that whenever one of the.

keys 5 is depressed the said bar 86 and the levers 81 82 84 are caused to movedownward. The end 88 of the lever 81, projecting beyond the shaft 85, is forked, Fig. 7, and engages a pin 89, fixed to the lever 91, iv oted at 90, this lever being normally pu led upward by a spring 92, so that the space-key 84 is also normally in an elevated position. A short vertical rod 94, pivoted at 93 to the lever 91, is connected to a lever 97, provided with a pawl 95 and pivoted at 96. he awl 95 gears into the teeth of a ratchet-whee 98, fixed to the paper-feed roller 44, so that every time the space-key 84 or one of the keys 5 1S depressed the paper-feed roller 44' is moved through one t0ot-hSpace. The roller 44 is of ebonite or similar material and is provided on its circumference with longitudlnal ribs.

The roller 45 is of soft rubber and is only rotated by friction, so that the paper strip 46, which is held between the two rollers with slight pressure, takes part in the movement of the roller 44that is to say, is shifted after each impression of a letter or after the operation of the space-key 84, the extent of'the movementbeing one letter-space corresponding to one tooth-space on the wheel 98. The ink-ribbon which has been used must also be shifted to the extent of one letter-space each time a letter has been printed, so that a fresh part of the ribbon is in position the next time it is required. The devices for moving the ink-ribbons are identical with each other, so that only one of them need be explained. The ribbons are wound on metal rollers 101, Fig. 9, in the known manner. At the side of each roller 101 is rigidly fixed a ratchetwheel 102, into the teeth of which gears a resilient pawl 104, pivoted to a lever 103. A finger 105, fixed to the latter, abuts against a lever 107, pivoted. at 106 and adapted to be lifted by means of a short lever 108 perpendicular thereto. The lever 108 is lntcgral with. the lever 60, pivoted at 61, Fig. 1. If, therefore, by striking the key 65 the ribbon 50 is moved into its working position, the lever 108 lifts the lever 107, and the latter operates the lever 10:;, so that the ribbon-roller is rotated through one tooth-space.

Having now fully described my invention, l. declare that what I claim is- 1. in a shorthand type-writing machine the combination of a plurality of ink-ribbons,

ITS

a platen contact-surface, of type-levers and means of striking said type-levers against said platen contact-surface, of fixed axes, levers and links, pivoted to said axes, an arm respectively connecting said levers and links, rib on-holders rigidly connected to said arm and means for o crating said levers to move said ribbondiol ers, substantially as and for the purpose set forth.

2. In a shorthand type-Writing machine, the combination of a plurality of ink-ribbons, a platen contact-surface, t e-levers and means for striking said typeovers a ainst said laten contact-surface,fixed axes, overs and inks pivoted to said axes, an arm respectively connecting said levers and links,

said contact-surface, of a platen-lever for the machine reception of said contact-surface, a fixed pivot with said platen-lever mounted thereon and means of oscillating said platen-lever and matrix around said pivot of feed-rollers 44, 45 for conducting a strip of paper 46 intermittently over the cylindrical surface of said platen-lever and means for causing said stri of paper to partake in the oscillation of sai platen-lever, substantially as and for the purpose set forth.

4:.In a shorthand type-writing machine adapted to print upon a strip of'paper, the combination of an oscillatory lever, a platen fixed thereto, a plurality of ink-ri bons, means for intermittently moving said strip ing said ribbons independently of each other 40 of paper over said platen and means for fee a
