 kraft stehenden Stangen 35 gesichert. Arme 36 gehen von dem Umschaltschieber nach oben und ihre oberen Enden sind zwischen den langen Armen der L-förmigen Teile 33 und den Naben 30 angebracht. 
 EMI2.1 
 der gegen den Arm durch den Stift   3-5   ausgeübte Druck wird die Radnabe entsprechend drehen, um den Eintritt des Rades 34 in den Ausschnitt 31 zu sichern. Diese Bewegung ermöglicht es dem Arm 33, auf einen der Arme 36 des Umschalters 33 zu wirken und bewegt letzteren der Länge nach, wodurch die L-förmigen Hebel 20 in der oben beschriebenen Weise ein Paar der Knaggen und Sperrklinken ausschalten und das andere Paar einschalten. 



   Es ist   klar, dass   der Tastenhebel mittels des Stückes 4 die Knaggen und Sperrklinken 18 in Bewegung setzt und so eine Bewegung auf das eine oder das andere der Sperräder 16 und durch diese auf die Farbbandräder übersetzt und dass, wenn die Umschalteinrichtung entweder durch Hand oder automatisch in Betrieb gesetzt wird, die Bewegung auf das andere Farbbandrad übertragen wird, um das Farbband in der entgegengesetzten Richtung laufen zu lassen. 



   PATENT-ANSPRÜCHE :
1. Farbbandschaltvorrichtung für Schreibmaschinen, bei welcher zwei lotrechte Farbbandspulenwellen jede durch konisches Räderwerk von zwei Sperrädern auf wagerechten Wellen getrieben werden, dadurch gekennzeichnet, dass die gegen den Mittelpunkt der Maschine nahe einandergebrachten Sperräder durch von hinten hervorragende Klinken betätigt werden, welche jede ausser Tätigkeit von je einem von zwei oben gelagerten seitlichen Hebeln   (20)   gehoben werden können, welch letztere durch einen   Umscbaltschieber     (2. 3) verbunden   sind, der mit einem auf-   wärtsragenden Mittelarm (24) versehen ist.

 force standing bars 35 secured. Arms 36 go up from the toggle slide and their upper ends are attached between the long arms of the L-shaped parts 33 and the hubs 30.
 EMI2.1
 the pressure exerted against the arm by pin 3-5 will rotate the wheel hub accordingly to secure entry of wheel 34 into cutout 31. This movement enables the arm 33 to act on one of the arms 36 of the toggle 33 and moves the latter longitudinally, whereby the L-shaped levers 20 deactivate one pair of the lugs and pawls and activate the other pair in the manner described above.



   It is clear that the key lever by means of the piece 4 sets the lugs and pawls 18 in motion and thus translates a movement to one or the other of the locking wheels 16 and through this to the ribbon wheels and that if the switching device is either manually or automatically is put into operation, the motion is transmitted to the other ribbon wheel to make the ribbon run in the opposite direction.



   PATENT CLAIMS:
1. Ribbon switching device for typewriters, in which two vertical ribbon spool shafts are each driven by conical gear train of two ratchet wheels on horizontal shafts, characterized in that the locking wheels, which are brought close to one another towards the center of the machine, are operated by pawls protruding from behind, which are each out of action one of two lateral levers (20) mounted on top can be lifted, the latter being connected by a reversing slide (2. 3) which is provided with an upwardly projecting central arm (24).
