KLASSE 69: Schneidwerkzeuge.CLASS 69: Cutting tools.
Patentirt im Deutschen Reiche vom 14. December 1882 ab.Patented in the German Empire on December 14, 1882.
Die Neuerungen beziehen sich auf eine Vorrichtung zum selbsttätigen Oeffnen des Messers und auf einen Mechanismus zum Geschlossenhalten der Klinge.The innovations relate to a device for automatic opening of the knife and a mechanism for keeping the blade closed.
Die Rückenfeder α ist gespalten und das abgespaltene Stück a1 weit vorgebogen. Drückt man die Klinge b zu, so wird damit die Feder β1 gespannt, welche die Klinge sofort wieder zurückwerfen wird, sobald man sie losläfst. Damit die aufgeklappte Klinge fest in ihrer Lage erhalten wird, ist am oberen Ende der Feder a ein Haken a2 angebracht, der in einen entsprechenden Ausschnitt b1 in der Klinge eingreift. The back spring α is split and the split off piece a 1 is pre-bent. If the blade b is pressed shut, the spring β 1 is tensioned, which will immediately throw the blade back as soon as it is released. So that the opened blade is held firmly in place, a hook a 2 is attached to the upper end of the spring a, which hooks into a corresponding cutout b 1 in the blade.
Zum Arretiren der Klinge b in geschlossener Lage dient der Stift c, welcher in dem schrägen Schlitz d der Schale verschiebbar ist. Beim Zuklappen der Klinge wird der Stift c durch die Klingenspitze nach dem unteren (hinteren) Ende des Schlitzes d geschoben, wo er auf die Feder e trifft, welche durch noch weiteres Niederdrücken gespannt wird. Ist der Stift infolge der schrägen Lage des Schlitzes d so weit zurückbewegt, dafs er an der Messerspitze vorbeipassiren kann, so kommt die Spannung der Feder e zur Wirkung, welche c wieder nach oben (nach vorn) schleudert, wodurch die Klinge festgehalten wird, da die eigene, auswärts strebende Tendenz der Klinge ein freiwilliges Zurückgleiten des Stiftes c verhindert. Um das Messer zu öffnen, mufs man den Stift c nach dem hinteren Ende des Schlitzes d zu drücken, dann springt die Klinge b infolge der Spannung der Feder a1 von selbst auf, Wobei sich der Haken a2 in den Ausschnitt b1 der Klinge einlegt und damit deren Zufallen hindert. The pin c, which can be displaced in the inclined slot d of the shell, is used to lock the blade b in the closed position. When the blade is closed, the pin c is pushed through the tip of the blade to the lower (rear) end of the slot d, where it meets the spring e , which is tensioned by pressing it down further. If, as a result of the inclined position of the slot d , the pin is moved back so far that it can pass the tip of the knife, the tension of the spring e comes into effect, which hurls c upwards (forwards) again, whereby the blade is held firmly there the blade's own outward tendency prevents the pin c from voluntarily sliding back. To open the knife, one has to push the pin c towards the rear end of the slot d , then the blade b springs open by itself as a result of the tension of the spring a 1 , whereby the hook a 2 is in the cutout b 1 of the blade inserts and thus prevents them from falling.
