Hs sind bereits Schreibmaschinen bekannt, bei denen durcli eine über die ganze Breite der Maschine reichende Dauinenwelle, die durch Auslösen eines Uhrwerks angetrieben wird, ein gewünschter Hebel des Typcnmechanismus so lange in Tätigkeit gesetzt und die diesem Hebel entsprechende Type wiederholt zum Abdruck gebracht werden kann, bis das Uhrwerk gesperrt wird. Diese Schreibmaschinen erfordern jedoch eine besondere verwickelte Bauart, und die Antriebvorrichtung kann nicht bei Schreibmaschinen anderer bekannten Bauarten angewendet werden. Außerdem werden bei dieser Art; Schreibmaschinen hohe Ansprüche auf die Aufmerksamkeit des Schreibenden gestellt, indem beim zögernden Niederdrücken einer Taste· die entsprechende Type leicht gegen seinen Willen mehrmals nacheinander zum Abdruck gebracht werden könnte.Typewriters are already known in which one over the entire width of the Machine reaching permanent shaft, which is driven by triggering a clockwork, a desired lever of the type mechanism is set in action for so long and this Lever of the appropriate type can be repeatedly imprinted until the clockwork is blocked. However, these typewriters require a special intricate one Type, and the drive device cannot be applied to typewriters of other known types. Also be with this species; Typewriters have high demands on the writer's attention by reluctantly pressing a key · the corresponding type could easily be reprinted several times in succession against his will.

Den Gegenstand der Erfindung bildet eine "Vorrichtung der erwähnten Art, die auf jeder Schreibmaschine ohne Umbau derselben angebracht: werden kann. Die Daumenscheibe besitzt nur die zum Antrieb eines Tastenhebel bzw. oincr Taste nötige Breite und ist auf einer oberhalb der Tastatur bzw. der Tastenhebel angeordneten Welle des seitlich am ■Maschinenrahmen angebrachten Uhrwerks aufgesetzt und erforderlichenfalls verschiebbar angeordnet, in welch letzterem Falle ein belie35 The subject of the invention is a "device of the type mentioned, which can be attached to any typewriter without having to convert the same. The thumb disk has only the width required to drive a key lever or key and is located above the keyboard or key lever placed arranged shaft of the laterally mounted on the machine frame ■ movement and disposed displaceably, if necessary, in which latter case a belie35

biger Tastenhebel bzw. eine beliebige Taste zum wiederholten Abdruck gebracht werden kann, während das gewöhnliche Schreiben in der üblichen Weise, ohne Inanspruchnahme dieser Vorrichtung, vor sich geht. Es können auch mehrere solche Daumenscheiben auf der Welle unabhängig voneinander verschiebbar angeordnet sein, um beliebige zweier oder' mehrerer Typen nacheinander zum wiederholten Abdruck bringen zu können.biger key lever or any key can be pressed again can, while the ordinary writing in the usual way, without recourse this device is going on. There can also be several such thumb discs on the Shaft can be arranged to be displaceable independently of one another to accommodate any two or ' to be able to reproduce several types one after the other.

Auf den Zeichnungen ist die neue Vorrichtung beispielsweise in zwei Ausführungsfor- ' men dargestellt. Die Fig. 1 bis 3 zeigen eine Ausführungsform der Vorrichtung, die zum Antrieb nur einer Taste eingerichtet ist. Fig. 1 zeigt die Vorrichtung in Seitenansicht. Fig. 2 ist eine Vorderansicht. Fig. 3 ist ein Grundriß zu Fig. τ, teilweise im Schnitt.In the drawings, the new device is for example shown in two Ausführungsfor- 'men. 1 to 3 show an embodiment of the device which is set up to drive only one key. Fig. 1 shows the device in side view. Fig. 2 is a front view. Fig. 3 is a plan view of Fig. Τ, partially in section.

Die Fig. 4 bis 6 stellen eine weitere Ausbildung der die Erfindung bildenden Vorrichtung dar, die den Antrieb einer beliebigen Taste ermöglicht. Fig. 4 zeigt die Vorrichtung in Seitenansicht. Fig. 5 zeigt dieselbe in Draufsicht. Fig. 6 ist Schnitt nach Linie X-X gemäß Fig. 5. " ■ ■ '4 to 6 represent a further embodiment of the device forming the invention, which enables any key to be driven. Fig. 4 shows the device in side view. Fig. 5 shows the same in plan view. Fig. 6 is a section along line XX according to Fig. 5. "■ ■ '

Das Antriebwerk, beispielsweise Uhrwerk 1 (Fig. 1), dessen Feder 2 zeitweise mit dem Schlüssel 3 aufgezogen werden kann, ist vorteilhafterweise analer Seitenwand der Schreibmaschine befestigt. In das Sperrad 4 greiftThe drive mechanism, for example clockwork 1 (Fig. 1), the spring 2 at times with the Key 3 can be wound, is advantageously the anal side wall of the typewriter attached. Engages in ratchet wheel 4

Claims

A two-armed pawl 5 with the action of a spring 6, after which the movement 1 is set in motion by pressing the button 7. The AVeMe 8 driven by the clockwork 1 is extended from the Uhnvcrkgehäusc to over the key 10 of the typewriter to be moved and given away with a thumbwheel 9, by means of which, when the shaft 8 rotates, the repeated, at regular intervals of time successively depressing the with the relevant character (point, line or the like.) provided key 10 is accomplished. If, for example, a line is to be underlined, one first pushes the paper carriage back to the beginning, then presses key 7 and holds it in this depressed position until the entire or the desired length of the line is underlined. In order to be able to move any key alternately through this device, the shaft 8 'according to the second embodiment according to FIG . 9 'can act on any key lever 20, which is arranged parallel to one another in a libeiie. The guide rod 13 is provided with transverse incisions 14 corresponding to the key lever distribution, into which engages a resilient nose 15 fastened to the fork 12. The fork 12 together with the eccentric clip 9 'can by means of the rod fastened to the fork 12 and provided with the button 17 16. The rod 17 still carries the pointer 18, which shows the current position of the eccentric disk 9 'on the scale 19 during displacement, which is advantageously attached to the side wall of the typewriter. can either act directly on one of the key levers 20 or it is, as FIG. 6 shows, provided with a ring 21 which is articulated with the in the Slot 23 guided push rod 22 is connected, so that one of the key levers is pressed down by the push rod 22. In the clockwork 1 'according to FIG. 4, the pawl 5' engages, instead of a ratchet wheel, in the wheel 4 'which is provided with only one tooth 24 and which is fastened on the shaft 8', the tooth 24 being arranged in such a way that the eccentric or thumb disk always remains in the highest position when adjusting the drive mechanism in order to facilitate the displacement of the eccentric via the keyboard. The clockwork is wound up, for example, by means of the lever 3 '. By attaching two or more thumb disks or eccentric disks 9 ', the strokes of which take place one after the other, one could, for example, advantageously achieve a line with a point or other other drawing combinations, such as are common with circlip disks. Patilnt-A ν Proverbs:

1. 'Device for' repeated type imprint by means of a clockwork driven Daiiinemyellc for Typewriters, characterized in that a disc (9 or 9 ') to move a button or type button on the above the Keyboard or the key lever arranged shaft (8 or 8 ') of the side of the machine frame attached clockwork is attached.

2. Apparatus according to claim 1, characterized characterized in that the thumb disk (9 ') is displaceable on the shaft (8') is arranged so that any key lever or cine any key in go Activity can be set.

3. Apparatus according to claim t and 2, characterized in that on the shaft (8 or 8 ') several thumb discs are arranged, which are independent of each other Can be set to repeat any two or more types to be able to print one after the other.
