    Vorrichtung zum Sperren der Nullstellvorrichtung gegen unrichtige Drehungen an Zählwerken.   



   Um zu verhüten, dass die   FlügolgriSe   an den   Nullstellvorrichtungen   von Zählwerken bei Rechen-oder ähnlichen Maschinen in einer Richtung gedreht werden, die der Nullstellung nicht entspricht, so dass falsche Ergebnisse in den vorzunehmenden Rechnungen entstehen oder Beschädigungen der Maschinen vorkommen können, ist nach der Erfindung auf der die Nullstellung   herbeifahrenden   Welle a, die die Zählräder b trägt, ein Zahnrad   c   angeordnet, in das eine eine Drehung dieses Rades c nur in einer Richtung gestattende Sperrklinke d eingreift. 



   In der Zeichnung ist eine Ausführung wiedergegeben, wie sie zweckmässigerweise bei einer Rechenmaschine mit einstellbaren Antriebzähnen verwendet werden kann. 



   Die unter der Wirkung einer Feder g stehende Sperrklinke d ist hier derart ausgebildet und an dem das Zählwerk tragenden Schlitten e so angebracht, dass eine Drehung der Welle a vermittelst des mit ihr verbundenen   Flügelgriffes f nur   in Richtung des eingezeichneten Pfeiles   x   möglich ist. Da die Welle a zum Zwecke der Nullstellung achsial verschoben werden muss, so ist das Sperrad c durch Feder und Nut mit der Welle a verbunden, so dass bei einer Drehung der Welle a das Rad c mitgenommen wird, während bei einer Verschiebung der Welle a das Sperrad c an seinem Orte verbleibt. 



   Selbstverständlich kann man das Sperrad c auch auf einem Teile der Rechenmaschine anordnen, der mit   der Nullstellwelle   in Bewegungszusammenhang steht, so dass die Sperrung mittelbar erfolgt.

    Device for locking the zero setting device against incorrect rotation of counters.



   In order to prevent that the FlügolgriSe on the zero setting devices of counters in calculators or similar machines are turned in a direction that does not correspond to the zero position, so that incorrect results arise in the calculations to be made or damage to the machines can occur, is according to the invention On the zero position approaching shaft a, which carries the counting wheels b, a gear c is arranged, in which a rotation of this wheel c engages only in one direction allowing pawl d.



   In the drawing, an embodiment is shown how it can conveniently be used in a calculating machine with adjustable drive teeth.



   The pawl d, which is under the action of a spring g, is designed in such a way and attached to the slide e carrying the counter that rotation of the shaft a by means of the wing handle f connected to it is only possible in the direction of the arrow x. Since the shaft a has to be axially shifted for the purpose of the zero position, the ratchet wheel c is connected to the shaft a by a tongue and groove, so that when the shaft a rotates, the wheel c is carried along, while when the shaft a is moved, Ratchet wheel c remains in place.



   Of course, the ratchet wheel c can also be arranged on a part of the calculating machine that is related to movement with the zeroing shaft, so that the blocking occurs indirectly.
