  Schaltschloss für Schreibmaschinen. 



   Die Erfindung bezieht sich auf den Zwischenraumschaltmechanismus des Papierwagens zur Bildung der Zeile bei Schreibmaschinen und bezweckt, diesen wichtigen Teil einer Schreibmaschine in seiner Wirkungsweise zu verbessern, gleichzeitig aber seine bauliche Einrichtung zu vereinfachen und seine Herstellung zu verbilligen. 



   Die Fig.   l   und 2 zeigen den Erfindungsgegenstand in seiner Ruhelage in Seiten-bzw. Vorderansicht, die Fig. 3 und 4 veranschaulichen gleiche Ansichten des Erfindungsgegenstandes in Wirkungsstellung. 



   Die um die Achse a drehbare Schwinge b trägt oben in bekannter Weise den in die Wagenfortschaltezahnstange   o   eingreifenden festen Zahn d, sowie den gleichfalls bekannten, um den Bolzen e in einer zur Ebene der Zahnstange   c   parallelen Ebene verschwenkbaren Zahn f. 



   Dieser   Zahn fist erfindungsgemäss   winkelförmig ausgebildet und legt sich mit seinem einen, ungefähr   wagrecht   verlaufenden Schenkel gin der Ruhelage des Zahnes, während seines Eingriffes in die Zahnstange   e   von unten gegen den Anschlag h an, während sein aufrecht stehender, den eigentlichen Eingriffszahn bildender Schenkel oberhalb seines Drehbolzens e durch ein, auf einem Stängelchen   i   (verstellbar) angeordnetes Gewichtchen i belastet ist. 



   Dieses Gewichtehen verdreht den   Zahn f entgegen der Wirkung   des Anschlages h, sobald er die Zahnstange e verlassen hat. (s. Fig.   3und 4). DerAnsehlag histalsFederansehlag,   ausgebildet, um die Bewegung des Wagens in die Stellung für den Zeilenanfang nicht zu behindern, was der Fall wäre, wenn der Anschlag h fest ausgebildet wäre. 



   Der Zahn f tritt in dem Augenblick aus der Zahnstange e heraus, in welchem durch Niederdrücken einer Taste der Arm k der Schwinge b abwärts gezogen und diese dadurch um ihre Achse a verdreht wird, so dass der feste Zahn din die Zahnung der Wagenschaltezahnstange c eintritt. Die beiden   Stellschräubchen        m dienen zur Begrenzung des Schwingenhubes in beiden Richtungen. 



   PATENT-ANSPRÜCHE :
1.   Schaltschloss   für Schreibmaschinen, bestehend aus einer, einen festen und einen verdrehbaren Zahn tragenden Schwinge, dadurch gekennzeichnet, dass der verdrehbare Zahn   (fi   winkelförmig ausgebildet und mittels eines Schenkels (g) mit einem Anschlage (h) zusammenwirkt, während der andere Schenkel durch ein Gewicht   (i)   (oder Feder) belastet ist, welches den Zahn entgegen der Wirkung des Anschlages   (h)   in der Zahnstangenebene zu verdrehen sucht.

  Key lock for typewriters.



   The invention relates to the gap switching mechanism of the paper carriage for forming the line in typewriters and aims to improve this important part of a typewriter in its operation, but at the same time to simplify its structural equipment and to make its manufacture cheaper.



   Figs. 1 and 2 show the subject of the invention in its rest position in side or. Front view, FIGS. 3 and 4 illustrate identical views of the subject matter of the invention in the operative position.



   The rocker b, which is rotatable about the axis a, carries above in a known manner the fixed tooth d engaging in the Wagenfortschaltezahnstange o, as well as the likewise known tooth f pivotable about the bolt e in a plane parallel to the rack c plane.



   According to the invention, this tooth is angularly shaped and rests with its one, approximately horizontally extending leg g in the rest position of the tooth, during its engagement in the rack e from below against the stop h, while its upright leg, which forms the actual engagement tooth, is above its Pivot bolt e is loaded by a weight i arranged on a stem i (adjustable).



   This weighting rotates the tooth f against the effect of the stop h as soon as it has left the rack e. (see Figures 3 and 4). The stop h is a spring stop, designed so as not to hinder the movement of the carriage into the position for the beginning of the line, which would be the case if the stop h were fixed.



   The tooth f emerges from the rack e at the moment when the arm k of the rocker arm b is pulled downwards by pressing a key and this is thereby rotated about its axis a, so that the fixed tooth din enters the toothing of the car gear rack c. The two adjusting screws m serve to limit the swing arm stroke in both directions.



   PATENT CLAIMS:
1. Locking mechanism for typewriters, consisting of a rocker bearing a fixed and a rotatable tooth, characterized in that the rotatable tooth (fi angularly formed and by means of a leg (g) interacts with a stop (h), while the other leg through a weight (i) (or spring) is loaded, which tries to turn the tooth against the action of the stop (h) in the rack plane.
