   Die sendende Person stellt die Walze mittels Knopfes k auf eine   bestimmte   verabredete   Kennziffer   am Index i ein und schreibt in den Brief oder das Depeschenformular die Zeichen der dann über der Skala t im Schlitz s erscheinenden Reihe, die den auf der Skala t abzulesenden   buchstaben   und Zahlen des Textes entsprechen. Für jeden Buchstaben bzw. jede BuchstabenKruppe (Wort) wird die Taste c niedergedrückt und für den nächsten Buchstaben bzw. Buchstabengruppe (Wort) die dann erscheinenden Reihenzeichen der Walze über Skala t benutzt usf. 



   Sobald nur der Empfänger die Kennziffer weiss, so kann er diese beim Index i einstellen und dann den Text mittels der Skala/. und der bei jedem Tastendruck hinter dem Schlitz s   erscheinenden Geheimzeichen zurückverwandeln.   



   Natürlich lassen sich mit dem Apparat die   mannigfachsten     Kombinationen.. uld Permu-   tationen treffen, so kann jedesmal eine   andere KelU1ziffer   gewählt werden, man kann diese auf Verabredung nach einer gewissen Anzahl von Buchstaben oder Worten wechseln ; man kann   verabreden,   dass nach jedem einzelnen oder einer bestimmten Zahl von Buchstaben oder Worten die Taste c nicht einmal, sondern je zweimal, je dreimal oder in progressiver Anzahl steigend,   niedergedrückt   wird, also nach dem ersten bzw. dem dritten Buchstaben oder Wort zweimal, nach dem zweiten bzw. vierten Buchstaben oder Wort dreimal oder viermal usw.

   The usage is as follows: The sending and the receiving person both have such a device, with the same number of character rows and the characters in these rows in the same order.



   The sending person sets the roller by means of button k to a certain agreed-upon code number at the index i and writes in the letter or the dispatch form the characters of the row that then appears above the scale t in the slot s, which correspond to the letters and numbers to be read on the scale t of the text. For each letter or each letter group (word) the key c is depressed and for the next letter or letter group (word) the then appearing row characters of the roller above scale t are used, etc.



   As soon as only the recipient knows the code, he can set it at index i and then enter the text using the scale /. and convert back the secret characters that appear behind the slot s each time a key is pressed.



   Of course, the most varied combinations can be made with the apparatus ... and permutations, so a different number can be chosen each time; this can be changed by appointment after a certain number of letters or words; You can agree that after each individual or a certain number of letters or words the key c is not pressed once, but twice, three times or increasing in a progressive number, i.e. twice after the first or third letter or word, after the second or fourth letter or word three or four times, etc.
