PATENTAMT.PATENT OFFICE.

Die' vorliegende Erfindung besteht hauptsächlich in der besonderen Zusammenstellung eines zwei oder mehr Typen tragenden Typenhebels mit einem Papierauflager in der Weise, dafs es von genannten Typen in beliebiger Reihenfolge auf der Druckzeile getroffen werden kann, wobei der Wechsel der unter einander parallelen Stellungen genannten Auflagers, welche den Typen verschiedener Ordnung entsprechen, rechtwinklig zur Ebene der Druckfläche der Type beim Auftreffen auf das Auflager erfolgt. In Verbindung mit dieser Neuerung umfafst die Erfindung ferner die Ausbildung der schwingenden Typenhebel mit zwei oder mehr zu einander geneigt stehenden Flächen zur Anbringung der Typen, um bei dem Wechsel der Stellungen, welche der Anzahl der Typen entsprechen , ' normal und in einer Linie auf die Unterlage aufzutreffen. Auch bezieht sich die Erfindung auf die gemeinsame Anordnung solcher mit mehr Typen versehener Typenhebel in Verbindung mit dem einem Stellungswechsel unterworfenen Papierauflager.The present invention consists primarily in the particular composition of one two or more types of supporting type levers with a paper support in such a way that it can be hit by the named types in any order on the print line, whereby the change of the mutually parallel positions called support, which the Types of different order correspond, perpendicular to the plane of the printing surface of the Type takes place when it hits the support. In connection with this innovation includes the Invention also the formation of the swinging type lever with two or more to each other inclined surfaces for attaching the types in order to change the positions, which correspond to the number of types 'to hit the surface normally and in a line. Also refers to Invention on the common arrangement of such type levers provided with more types in connection with the changed position of the paper support.

Fig. ι ist ein verticäler Längsschnitt durch die Mitte der mit der neuen Einrichtung versehenen Maschine beim Vorgang des Drückens mit einer der inneren Typen (für die kleinen Buchstaben).Fig. Ι is a vertical longitudinal section through the center of the provided with the new device Machine in the process of spinning with one of the inner types (for the little ones Letters).

Fig. 2 ist eine ähnliche Ansicht der Maschine beim Vorgang des Drückens mit der anderen an demselben Hebel befindlichen Type (für einen grofsen Buchstaben).Figure 2 is a similar view of the machine in the process of spinning with the other Type on the same lever (for a large letter).

Fig. 3 ist eine Darstellung einer Abänderung des Typenhebels und der bezüglichen Hubstellungen der Papierwalze.Fig. 3 is an illustration of a modification of the type lever and the related stroke positions the paper roller.

Fig. 4 und 5 zeigen in Ober- und Seitenansicht einen der neuen Typenhebel in gröfserem Mafsstabe.FIGS. 4 and 5 show, in top and side views, one of the new type levers in a larger size Yardstick.

. Bei der dargestellten Typenschreibmaschine sind die Typenhebel A* im Kreise mit radialen Schwingungsebenen angeordnet, so dafs ihre Drehpunkte in einer gemeinsamen Ebene liegen und alle Hebel auf die gemeinsame Druckstelle, den Mittelpunkt des Kreises, auftreffen können. Die Typenhebel werden, wie ersichtlich, durch die üblichen Tastenhebel bethätigt. Die Form und Anordung der Typenhebel, sowie die besondere Anschlagvorrichtung ist unwesentlich und kann in mannigfacher Beziehung abgeändert werden.. In the typewriter shown, the type levers A * are arranged in a circle with radial oscillation planes so that their pivot points lie in a common plane and all levers can hit the common pressure point, the center of the circle. As can be seen, the type levers are operated using the usual button levers. The shape and arrangement of the type levers, as well as the special stop device is insignificant and can be changed in many ways.

Das Papierauflager oder die Walze B ^x ist derart angeordnet, dafs sie einen Hubwechsel in einer Richtung wesentlich rechtwinklig zu der Ebene ausführen kann, in der die Drehpunkte sämmtlicher Typenhebel liegen; die Walze kann demnach zwei oder mehr Stellungen einnehmen, die zu einander parallel und rechtwinklig zur Druckfläche einer Type sind, sobald dieselbe auf das Papier auftrifft und einen Buchstaben druckt.The paper support or the roller B ^x is arranged in such a way that it can perform a stroke change in a direction substantially at right angles to the plane in which the pivot points of all type levers are located; the roller can accordingly assume two or more positions which are parallel to one another and at right angles to the printing surface of a type as soon as the same hits the paper and prints a letter.

Der Hubwechsel der Walze in der bezeichneten Richtung kann dadurch eingerichtet werden, dafs der Schlitten C^x und dessen Gleitbahnen c^x zu einer Bewegung vertical zur Ebene der Typenhebeldrehpunkte veranlafst wird. Zu diesem Zwecke können seitliche Schubstangen d^x, die in Führungen e^x gleiten, an die Unterseite des Schlittengeleises c^x bei jedem Ende desselben angreifen; durch an Stifte von d^x angreifende Arme /^x einerThe stroke change of the roller in the indicated direction can be set up by causing the carriage C ^x and its slideways c ^x to move perpendicular to the plane of the type lever pivot points. For this purpose, lateral push rods d ^x , which slide in guides e ^x , attack the underside of the carriage track c ^x at each end thereof; by arms attacking pins of d ^x ^{/ x} one

Claims

common rotating rod g * , the movement can be initiated by means of a key lever h ^x , the associated key of which may be in the keyboard of the machine. The type of motion transmission to the paper support is incidentally insignificant for the purpose of the invention. . . ■

As soon as a> type lever A ^x swings out and is about to hit the paper roller with one of the types, as can be seen in FIGS or the support comes together. The arrangement of the roller therefore makes it possible, in alternating order, to obtain an imprint of the two types of type carried by each type lever on the same print line, in such a way that the number of different positions of the roller corresponds to the number of types on a lever. Such a type lever for two or more types is designed in such a way that the printing planes of the individual types are at an angle to one another, as shown in Fig. 1, 2, 4 and 5 on a lever carrying two types in Fig. 3 is shown on a type lever with three types. The angles at which the printing planes of the individual types are arranged correspond to the changes in position to which the paper support is subjected, the printing surface of a type striking the roller and exactly in the line when the roller is in its relative position.

In Fig. Ι the type lever is when it hits the closer to the pivot point Type shown, with the roller in the lowest position, and in Fig. 2 meets the Type lever with the second type on the paper after the roller is in its upper position is lifted by a movement at right angles to the printing plane. The type lever swings in the latter case further around its pivot point in order to come into contact with the printing substrate come. In the described way it is possible to combine several types of letters with one Print type lever on the same line. *

It is preferred to give the type lever only two types and on one of the inclined surfaces, expediently the outer or end surface, one of the large letters, on the other surface closer to the pivot point, one of the small letter characters of the same alphabet. By virtue of this arrangement one becomes with the normal position of the roller (Fig. 1) print small letters by hitting the keys, and when it is necessary to print a large letter one has only the cylinder to the position shown in Fig. 2, with the other type printed on the same line will.

The assumed circular and radial arrangement of the type levers requires a relative one Differences in the position of the type symbols on the associated levers by adding the types on all of the type levers, whose longitudinal axis is different from right-angled to the longitudinal axis of the roller, its type center lines in parallel to the paper roller axis as can be seen in FIG.

When the paper ^{roller carriage C x} is displaced perpendicular to the plane in which the printing takes place, the switching device causing a transverse movement of the paper roller, which was not shown as not belonging to the invention, is lifted so that one for each position of the carriage Movement of the same to complete the printing of characters next to each other is possible.
