PATENTAMT.PATENT OFFICE.
Die bisher bekannt gewordenen Zähnungsschlüssel aus Celluloid oder Pappe für die Prüfung von Briefmarken u. dgl. haben, abgesehen von ihrer geringen Haltbarkeit, den Nachteil, daß die Teilungen mit den Vervielfältigungsmitteln des Buchdruckes oder verwandter Druckarten hergestellt sind. Es hat sich nun gezeigt, daß diese aufgedruckten Teilungen einem sehr schnellen VerschleißeThe previously known toothing keys made of celluloid or cardboard for Testing of postage stamps and the like have, apart from their low durability, the Disadvantage that the divisions with the means of reproduction of the letterpress or related Types of printing are made. It has now been shown that these are imprinted Divisions wear out very quickly
ίο unterliegen und daher in kürzester Zeit undeutlich bzw. unbrauchbar werden. Außerdem ermüdet das Auge des Sammlers besonders bei den engeren Stellen der Teilung mangels körperlicher Anhaltspunkte, da die gewöhnlich punktförmig oder in ganz kleinen Kreisen angegebenen Zähnungsmensuren in der Papierebene liegen und deshalb bei fortgesetztem längeren Arbeiten unruhig werden.ίο are subject and therefore indistinct in a very short time or become unusable. In addition, the collector's eye is tired, especially in the narrower parts of the graduation physical clues, as these are usually given as points or in very small circles Perforation marks lie in the plane of the paper and therefore become restless if you continue to work for a long time.
Die vorliegende Erfindung bezweckt nun eine Verbesserung durch die Herstellung von Zähnungsschlüsseln, welche der Abnutzung praktisch nicht unterliegen und außerdem dem Auge einen sicheren Anhaltspunkt geben, sowie die rasche Ermüdung durch Mithilfe des Tastsinnes verhindern und deshalb das Arbeiten mit dem Zähnungsschlüssel wesentlich erleichtern.The present invention now aims to improve upon the manufacture of Serration keys, which are practically not subject to wear and tear, and also give the eye a safe point of reference, as well as the rapid fatigue through assistance prevent the sense of touch and therefore working with the toothing wrench is essential facilitate.
Zu diesem Behufe werden in eine Platte, welche z. B. aus dünnem Stahlblech bestehen kann, stäbchenförmige Erhöhungen an den Teilpunkten eingesetzt oder eingepreßt, so daß die zu prüfenden Marken rasch und sicher in die von den Stäbchen gebildeten Zwischenräume eingepaßt werden können, wobei das Auge durch den Tastsinn unterstützt wird.For this purpose, in a plate which z. B. consist of thin sheet steel can, rod-shaped elevations inserted or pressed in at the sub-points, so that the marks to be tested quickly and safely into the spaces formed by the chopsticks can be fitted, with the eye being supported by the sense of touch.
In der Fig. 1 bedeutet α die Platte, b die stäbchenförmigen Erhöhungen, welche in derIn Fig. 1, α means the plate, b the rod-shaped elevations, which in the
üblichen Teilung (z. B. n/2 undusual division (e.g. n / 2 and
(η+ ι) (η + ι)
auf jeon ever
20 mm) eingesetzt sind. Fig. 2 und 3 zeigen die Vorder- bzw. Rückseite des Instrumentes. Die Ränder der Platte α können etwas geschärft sein, um auch in Sammelmappen befestigte Marken bequem zu prüfen.20 mm) are inserted. Figures 2 and 3 show the front and rear of the instrument, respectively. The edges of the plate α can be sharpened to make it easy to check brands attached to folders.
Zur weiteren Erleichterung des Arbeitens mit dem Zähnungsschlüssel werden zweckmäßig Schrift und Striche auf hellem Grunde, die Oberflächen der stäbchenartigen Erhöhungen in dunklen Farben gehalten.To make working with the toothing key even easier, it will be useful Writing and lines on a light background, the surfaces of the rod-like elevations kept in dark colors.
