CHANGEABLE TYPE FQR TYPE-WRITERS Specification of Letters Patent.
Patented Aug. 11, 1908.
Application filed October 5, 1906. Serial No. 337,519.
To all whom it may concern: 1 Be it known that I, GABRIEL MAoIs, a sub- 'ect of the Emperor of Russia, residing at St. etersbu'rg, Russia, have invented new and useful Improvements in Changeable Types for Type-Writers, of which the following 1s a specification, reference being had to the annexed drawing.
In all the most perfect t pewriters, as for instance, the Remlngton, I lnde'rwood, Ideal and other systems, 1n which each printing lever is furnlshed with one letter block, it is possible to print only with one type, i. e. Russian or Latin. For changing the type in these machines it is necessary to change all the levers with the letters, which can be fulfilled only by a specialist and with a considerable loss of time. The present invention does away with this drawback and affords a possibility to change the types in these machines quickly by everybo even by an altogether inexperienced person, working on the machine.
The important feature of the machine is in the fact, that the letter block does not form one whole iece with the lever and is not fastened rigi y to the same, but constitutes a separate part, connected in hin e-fashion w1th the lever, in such a manner, t at it can be turned into a certain position, in which it is held with the aid ofa spring. Theblock is principally made tetrahedral, although it may also have a larger number of sides. Eachside may be furnished with letters of an alphabet or other signs, so that by turning all the letters into a certain osition, it is possible to make use of either a phabet.
The machines affording most convenience in typing, are those in which one sign or let ter is marked on the key and therefore in ehangin the v alphabet, when turning the letter b ocks, it 15 necessary to change the letters or signs on the keys, accordingly. An opening is made for this purpose in the key, in which the letters or slgns corresponding with the changed alphabet ma appear.
On the annexed drawing, igure 1 represents, as an exam le, a side view of the letter lever of the nderwood ty ewriter, furnished with the proposed movab e letter;
Fig. 2 is an edge view of this lever; Figs. 3 and p 4 represent, in a larger scale, a side view and plan of the movable letter block, held in a certain position by a s iral spring; Fig. 5 is a side View of the letter lock, which is held in prop'er position by a flat spring; Figs. 6 and 7 represent a plan and side view of a key furnished with changeable letters.
The letter block 1, having a tetrahedral form preferably, is located with its journals inlugs 3 and 4, which are cast to the ends of lever 2. One journal of the block ends in the shape of a square head 5, by means of which block 1 may be turned with the aid of a key in either dlrection. In each of the certain positions, the letter block is held in place by meansof a spiral spring 6, pressing the stem 7 (Fig. 3) or with the aidof a -flat s ring 8, pressing directly against the block FFig. 5).
An arrangement is shown in Figs. 6 and Z for changing the letters on the keys, in accordance with the change of the alphabet on the letter levers. This arrangement is made so that there is an opening 10 in key 9, in which a letter or other sign may appear, this latter being fixed on a s rin lever 11, for which purpose it is moved y the finger in the proper direction and is kept in a certain position, owing to its entering slot 12, made in the head of key 9.
Claims.
1. A type-bar for ty ewriting machines, having lugs at'the en of said type-bar, a
ty e-head provided with two types and ourna ed between the lugs aforesaid, a part formed with said t pe-head, for engagement by a key, to turn the same, and a spring carried by the ty e-bar and pressing against the underside of t e type-head.
2. A type-bar for typewriting machines, having lugs at the end of said type-bar, a type-head provided with two types and with journals fitted between the lugs aforesaid, a part integral with said type-head and pro- Lecting from one of the lugs, for engagement y a key to turn the same, and a spring carried by the ty e-bar and pressing against the underside of t e typehead.
In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
