UNITED STATES 1 PATENT OFFICE.
ERNST WILHELM ERAcKELsBERG, or onLIGs, GERMANY.
TYPE-WRITING MACHINE.
SPECIFICATION forming part of Letters Patent No. 660,556, dated October 30, 1900.`
Application filed December 16. 1898 u erial No. 699,489. (No modell To LZZ whom, t may concern.-
Be it known that LERNsT WILHELM BRACK- ELSBERG, a subject of the Emperor of Germany, residing at Ohligs, Germany, have in vented certain new and useful Improvements in Type-Writing INIachines, of which the following is a specification.
In type-Writing machines which comprise wheels or segments bearing types or characters the construction is based on the principle of mounting such Wheels or segments on a common axle. By reason of this form of construction it is necessary to employ bent or curved bars for the purpose ot' connecting the type-wheels, which are positioned close together, with the mechanism of the several keys, which are located farther apart, or when it is desired to avoid the use of such bent or curved bars it is necessary to arrange the hubs of the several type-wheels telescopically or fitting one in the other. One illustration of this arrangement occurs in machines for casting up or adding figures, in which, hoW- ever, the bent or curved bars are held within practicable limits, -owing to the fact that the keyboard, comprising only the numbers from naught to nine, has only one row of keys and will therefore occupy but little space; but in the case of keyboards having a greater number of characters the use of such bent or curved bars results in great disadvantages in the Working of the machine. In my invention each type wheel or segment has an individual axle. The axles have bearings in the frame of the machine, in Which they are supported in a firm manner adapted to meet all requirements. The length of these axles is not necessarily limited, so that it is possible to employ several rows of keys and a corresponding number of segments or type-wheels. In my invention the radii of the type wheels or segments Vary; but they diier only by the distance apart of their respective axis.
The accompanying drawings, which form a part of this application, illustrate one form of myinvention.
In the drawings, Figure l is a top plan View of my type-Writing machine, and Fig. 2 is a vertical longitudinal section takenthrough the center of Fig. l.
As shown in the drawings, my machine has four keyboards or groups of keys, which are lettered, respectively, h h h2 h3, each compris: ing three rows of separate keys arranged in horizontal and perpendicular lines. The first or left-hand keyboard contains the punctua' tion characters, the second keyboard contains the capital letters of the alphabet, and the third and Jfourth keyboards each contain an alphabet of small letters. The stems of the keys are guided in suitable openings'in hori-v zontalA plates, as ci', and are held in their normal positions by coil-springs surrounding the stems and having one end secured to the latter and the other end to the plate 'L'. When the keys hare depressed, they strike the plate f, arranged below said keyboard and secured to the lever e, which is pivoted at its forward end to the shaft 7c, arranged at the front of the machine and having suitable bearings in the frame of the latter. To the rear end of the lever e is pivoted a vertical rod c, which in turn is pivoted at its upper end to the short lever CZ, to which is secured the axle l), which operates the segment a: Each of the keyboards is arranged and constructed and operates in a manner exactly like that just described, and each one has a corresponding axle and type-bearing segment. Each key has an individual or peculiar stroke limited by shoulders formed at different points on the key-stems, which strike on the plate 'i' as the keys are depressed, so that the position of the characteron the segmentoperated through the medium of said key will correspond with the character on the key which is being operated. On releasing the depressed keys the segments will be returned to their normal positions of rest bythe action of suitable sp rings which bear against the under side of the levers c, e', e2, and e3, as will be readily understood. The axles of the respective segments are arranged parallel and in such a manner that on the left-hand side there are the axles b b, the former slightly in rear of the latter, and on the right-hand side the axles b2 and b3, the latter in the rear of the former. By arranging the axles b b3 in the same alinement and the axles b b2 in the same aline. ment there will be required only two dierent radii for the segments. For the purpose of effecting the accurate alinement of the types or characters at the point of impression the innerside of each segment has formed therein IOO notches Which correspond in position and number to the types or characters. Positioned for engaging these notches is a 1ever j, which may be operated in any suitable manner.
The mechanism for feeding the paper for in king the type is not described nor shown in this application, because the same does not come Within the scope of this invention.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. A type-Writing machine comprising several Wheels or segments bearing characters Situated side by side, said Wheels or segments being mounted on rotary axles corresponding in number to the number of the Wheels or segments, said axles being arranged side by side and key mechanism for rotating said axles, substantially as set forth.
2. A type-Writing machine comprising several Wheels or segments bearing characters situated side by side, said Wheels or segments being mounted on rotary axles corresponding in number to the number of Wheels or segments, said axles being arranged side by side, and means for rotating said axles consisting of pivoted levers corresponding in number to the number of the axles and secured thereto by rods and levers, and means for depressing said rstnamed levers consisting of keys having characters indicated thereon, and each key having a limit to its vertical movement peculiar to itself, substantially as set forth.
3. A type-Writing machine comprising several Wheels or segments bearing characters situated side by side, said wheels or segments being mounted on rotary axles corresponding in number to the number of the Wheels or segments, said axles beingarranged side by side, key mechanism for rotating said axle, and each of said segments having notches on its inner side, a pivoted lever adapted to engage said notches, and means for operatingsaid lever, substantially as described.
