Durch das Hauptpatent 191726 ist eine Vorrichtung zur Längs- und Querbewegung eines der hintereinanderliegenden Farbbänder von Schreibmaschinen unter Schutz gestellt,, bei der die aufwickelnde der Spulen der beiden Farbbänder nach Wahl von einem Triebrad gedreht wird, das in bekannter Weise auf einer schwingbar gelagerten und von einem Schaltrad aus angetriebenen Welle zwischen den Triebrädern je zweier benachbarter Spulen angeordnet ist. Je nachdem die Welle nach einwärts oder nach auswärts geschwungen wird, kommt ihr Triebrad mit dem Triebrad der einen oder der anderen Spule zum Eingriff; es wird daher immer nur das eine FarbbandThe main patent 191726 is a device for longitudinal and transverse movement one of the consecutive ribbons of typewriters placed under protection, in which the winding of the coils of the two ribbons of the choice of a drive wheel is rotated in a known manner on a swingable and supported by a Ratchet wheel from driven shaft between the drive wheels of two adjacent coils is arranged. Depending on whether the wave is swung inwards or outwards, if your drive wheel meshes with the drive wheel of one or the other coil; therefore there is always only one ribbon

Es hat sich als wünschenswert herausgestellt, die nach dem Hauptpatent durch einen Schieber bewirkte Verbindung zwischen den beiderseits der Maschine angeordneten schwingbaren Antriebwellen zu vereinfachen. Ferner hat sich gezeigt, daß zuweilen unbeabsichtigte Bewegungen desjenigen Farbbandes oder der zugehörigen Spulen eintreten, die in Ruhe verbleiben sollen. Dann treten leicht Störungen dadurch ein, daß · das zwischen den Spulen sitzende Stück des außer Tätigkeit befindlichen Farbbandes an seiner Farbbandgabel herabsackt und von der anderen Farbbandgabel mitgerissen wird und somit fälschlich in die Bahn der Typen gelangt.It has been found to be desirable according to the main patent by a slide brought about a connection between the arranged on both sides of the machine to simplify oscillating drive shafts. It has also been shown that sometimes unintended Movements of that ribbon or the associated coils occur that should remain at rest. Then step lightly Disturbances caused by the fact that the piece of the inactive piece sitting between the coils The ribbon sags on its ribbon fork and from the other ribbon fork is carried away and thus wrongly gets into the path of the types.

Nach der Erfindung wird daher die Verbindung zwischen den beiderseits gelagerten Antriebwellen, anstatt durch einen im Maschinengestell besonders geführten Schieber, durch eine einfache, entsprechend gebogene Stange bewirkt, die einer besonderen Lagerung oder Führung am Maschinengestell nicht bedarf. Ferner ist eine Vorrichtung vorgesehen, durch die in einfacher Weise das jeweilig stillstehende Farbband durch Verriegelung seiner Spulen an der Ausführung unbeabsichtigter Bewegungen verhindert wird. Der gesamte Mechanismus ist einfach und kann in vorhandene Maschinen eingebaut werden.According to the invention, the connection between the drive shafts mounted on both sides is therefore instead of a slide specially guided in the machine frame, a simple, appropriately curved rod causes that do not require special storage or guidance on the machine frame. Furthermore, a device is provided through which the respective stationary Ribbon by locking its spools from making unintentional movements is prevented. The whole mechanism is simple and can be used in existing machines to be built in.

Auf der Zeichnung ist der Erfindungsgegenstand' in einer beispielsweisen Ausführungsform dargestellt. Fig. 1 zeigt den Antrieb der Farbbandspulen auf einer Seite der Maschine. Fig. 2 veranschaulicht die Hauptteile des Antriebes gemäß Fig. 1, aber mit entgegengesetzter Stellung der Antriebwelle. Fig. 3 zeigt die Verbindung der beiden auf entgegengesetzten Seiten der Maschine liegenden Antrieb wellen. Fig. 4 zeigt die Verriegelvorrichtung für die Spulen von oben gesehen, und Fig. 5 veranschaulicht eine Feststellvorrichtung für die Antriebwellen in ihren jeweiligen Endstellungen.:The subject of the invention is shown in an exemplary embodiment in the drawing shown. Fig. 1 shows the drive of the ribbon reels on one side of the machine. Fig. 2 illustrates the main parts of the drive according to Fig. 1, but with the opposite Position of the drive shaft. Fig. 3 shows the connection of the two on opposite sides Drive shafts lying on the sides of the machine. Fig. 4 shows the locking device for the Coils seen from above, and Fig. 5 illustrates a locking device for the Drive shafts in their respective end positions .:

The front ribbon 2 is on spools 4

Claims

wraps, one of which is on both sides of the pressure point. The rear ink ribbon 3 is carried by reels 5 arranged outward from the reels 4. Their. The 'spools of gears' 6 and 7 are driven. Between these gears is the associated drive wheel 8, which, as described in patent 191726, sits on an upright, oscillating shaft 9 /, t. This receives its drive from a bevel gear 10, which is in engagement with the bevel gear 11 and is rotated by a ratchet wheel 12 through this in a known manner. The shaft 9 lies in bearings 13, 14 which are seated on an upright carrier 15. At its lower end, this is pivotably mounted on a pin 16. A shaft 9 and a carrier 15 are arranged on each side of the machine. The carriers 15 can be adjusted by a two-armed lever 17 (Fig. 3) which engages the carrier 15 on the right side of the machine and is connected by a rod 18 to the carrier 15 on the left side. The connection between the lever 17 and the carrier 15 on the right-hand side of the machine is made by a joint piece 19. The lever 17 is mounted at 20 on the machine frame; By pressing the button 21 or the button 22 with a finger, the two carriers 15 with the shafts 9 mounted in them can either be operated in a known manner. be moved inwards so that they come into engagement with the drive wheels 6 of the bobbins 4 (position according to FIG. 3), or are moved outwards so that they come into engagement with the drive wheels 7 of the bobbins 5. The two carriers 15 are held in their respective positions by the action of a spring 23 which presses a ball 24 against an eye 25 (FIG. 5) in which the pivot pin 26 for the rod 18 engaging the left-hand carrier 15 is fastened. At the upper end of the carrier 15 a flat spring with the two arms 28 and 29 is fastened by a screw 27, which come with upwardly bent fingers 30 and 31 for engagement with one of the wheels 7 and 6 when the carrier is placed in one of its end positions . If the carrier 15 is in its inwardly inclined position (FIG. 3), the fingers 31 on the right and the fingers 30 on the left engage in the drive wheels 7 of the bobbins 5; in the other position, however, the other fingers are in engagement with the wheels 6 of the reels 4. Each time there is a locking of those coils that are not in engagement with the relevant drive wheels on the shafts 9, and an unintended effect of the inoperative ribbon is therefore prevented. The suspension of the arms 28 and 29 ensures that the fingers 30 and 31 also come into engagement if they should strike the head of a tooth. Ρλτε ν τ-Α ν Proverbs:
