 EMI2.1 
   ist auf   einem am   Schreibmaschinengestell 27 angeordneten   Zapfen 33 drehbar gelagert, und seine Drehbewegung wird durch zwei Stifte 34 begrenzt. Diese Anordnung ist so getroffen, dass beim Umlegen des Handhebels 29 in die eine oder andere Endstellung der die Verbindungsstange 24 bewegende Hebel 28 mit dem Zapfen 25 über die Totpunktstellung hinausgelangt. Dadurch wird erreicht, dass der Handhebel 29 in seinen Endstellungen durch die Wirkung der Feder 18 gegen den einen oder anderen Anschlagstift 34 gepresst gehalten wird, so dass sich für ihn eine besondere   Feststellvorrichtung erübrigt.   



   Nimmt der Handhebel 29 die untere Stellung ein, so wird Normalschrift geschrieben, d. h. die Schaltklinke 6 schwingt nur um eine Zahnteilung des Schaltrades 35 zurück, so dass die Schaltklinke 6 die mittlere der drei puktierten Stellungen gemäss Fig. 1 einnimmt, wobei sie gegen den entsprechend eingestellten Anschlagschaft 16 schlägt (Fig. 1 und 3). Ist dagegen der Handhebel 29 so eingestellt, wie in Fig. 1 punktiert gezeichnet, wobei die veränderte Lage des Hebels 28 mit der Zugstange   31,   der Verbindungsstange 24 und der Schaltplatte 22 gleichfalls punktiert dargestellt ist, so wird   Sperrschrift   geschrieben, d. h. die Schaltklinke 6 schwingt um den doppelten

 EMI2.1
   is rotatably mounted on a pin 33 arranged on the typewriter frame 27, and its rotational movement is limited by two pins 34. This arrangement is made such that when the hand lever 29 is turned into one or the other end position, the lever 28 moving the connecting rod 24 with the pin 25 extends beyond the dead center position. This ensures that the hand lever 29 is held in its end positions by the action of the spring 18 pressed against one or the other stop pin 34, so that a special locking device is unnecessary for it.



   If the hand lever 29 is in the lower position, normal script is written, i.e. H. the pawl 6 swings back only one tooth pitch of the ratchet wheel 35, so that the pawl 6 assumes the middle of the three dotted positions according to FIG. 1, striking against the correspondingly set stop shaft 16 (FIGS. 1 and 3). If, on the other hand, the hand lever 29 is set as shown in dotted lines in FIG. H. the pawl 6 swings twice
