Description

Antriebsvorrichtung für die Tastenhebel an Schreibmaschinen. Es sind bereits Vorrichtungen zum mechanischen Antrieb -der Tastenhebel von Schreibmaschinen, wie sie ,für Vervielfältigungszwecke in Frage kommen, bekannt. Die .bekannten Einrichtungen bestehen im @"vesentlichen in einem afrollbaren gelochten Bande, das mittels Übertragungsmittel die Bewegung der Tasten- und (der mit ihnen gekuppelten Typenhebel hervorruft.Drive device for the key levers on typewriters. There are already devices for the mechanical drive - the key levers of typewriters, known as they are eligible for reproduction purposes. The known facilities essentially consist of a perforated band which can be rolled up and which is conveyed by means of a transmission medium the movement of the keys and (of the type levers coupled to them.

Demgegenüber ist der Erfindung gemäß das aJbrollbare Band an Stelle von Lochungen mit stiftartigen Vorsprüngen versehen, welche durch Druck auf die ansatzartig verlängerten Tastenhebel deren Aussahiv singen verursachen.In contrast, according to the invention, the rollable tape is in place of holes provided with pin-like projections, which by pressure on the slightly elongated key levers which look like singing.

Die Erfindung ist in der Zeichnung in einem Ausführungsbeispiel veranschaulicht, und zwar zeigt ;Abt. i in schematischer Darstellung die Gesamtanordnung des; SchreibmaschInenmechanismus mit der neuen Antriebsvorrichtung, während .The invention is illustrated in the drawing in an exemplary embodiment, namely shows; Dept. i a schematic representation of the overall arrangement of the; Typewriter mechanism with the new drive device while.

Abb. 2 die Ansieht und Abb. 3 den Querschnitt des abgerollten Antriebsbandes :für sich. darstellen.Fig. 2 the view and Fig. 3 the cross section of the unrolled drive belt :for themselves. represent.

,Abt. ¢ -zeigt die Befestigung der stiftartigen Vorsprünge in vergrößertem Maßstäbe. In den Abbildungen bedeutet a einen Tastenhebel einer Schreibmaschine, an welchem in bekannter Weise ein Typenhebel b derart angelenkt ist, daß heim Niedergehen des Typenhebels b @die Type c gegen die Schreibw walze d schlägt. Der Tastenhebel a besitzt erfindwgsgemäll an seinem worderen Ende einen Ansatz e, (der als Anschlag aiusgabildet ist. Der Tastenhebel a wird mittels einer 'Feder f gegen die stiftartigen Vorsprünge g des Antriebsbandes h gedrückt. Das Antriebsband h ist Über eine (Leitwalze i geführt rund wird von einer Rolle j ab- und auf eine Rolle k aufgewickelt. Die Bewegung des Antriebsbandes h kann sowohl von Trend wie mittels eines beliebigen mechanischen Antriebes, ;#velcher entiweder durch Federwirkung oder motorisch erfolgen kann, bewirkt werden. Die stiftartigen Vorsprünge g sind in beliebiger !Weise, «. B. durch. Verschraubungen L, in Odem Antriebsband, h !befestigt., Dept. Shows the attachment of the pin-like projections on an enlarged scale. In the figures, a means a key lever of a typewriter on which a type lever b is articulated in a known manner in such a way that the type lever b @the type c hits against the writing roller d when the type lever goes down. According to the invention, the key lever a has an extension e at its previous end (which is formed as a stop. The key lever a is pressed against the pin-like projections g of the drive belt h by means of a spring f. The drive belt h is guided around a guide roller i is unwound from a reel j and wound onto a reel k. The movement of the drive belt h can be brought about by trend as well as by means of any mechanical drive, either by spring action or by motor. The pin-like projections g are in in any! way, ". B. by. screwed connections L, in the drive belt, h! fastened.

Die Wirkungsweise (der neuen Vorrichtung ist die, daß die stiftartigen Vorsprünge g des Antriebsbandes h nacheinander gegen die Ansätze c der Tastenhebel d schlagen, wodurch die Typenhebel b in der !bekannten Weise bewegt werden.The mode of operation (of the new device is that of the pen-like Projections g of the drive belt h successively against the approaches c of the key lever Hit d, whereby the type lever b are moved in the known manner.

Der Vorteil (der neuen Antriebsvorrichtung dem, Bekannten gegenüber besteht darin, daß ein Antriebsband .für eine größere Anzahl verschiedener iSchrifts?ätze benutzbar ist, -da die stiftartigen Vorsprünge jederzeit in beliebiger Anordnung auf demAntdebsb!and, versetzt werden können, während beispielsweise ein mit Lochungen versehenes Antriebsband nur für einen einzigen Schriftsatz zu verwenden isst.The advantage (of the new drive device over the familiar consists in the fact that a drive belt .for a large number of different fonts can be used because the pin-like projections can be arranged at any time auf demAntdebsb! and, while, for example, one with perforations provided drive belt to use only for a single brief.
