DrehstiftPivot pin
Bei den bekannten Drehstiften mit aufgeschraubter Spitze kommt es sehr häufig vor» daß eioh der Minenleitkanal in der Spitze durch au Bruch gegangene Minenteile verstopft« Wird in einem solohon Falle versucht, die Torsohttbmeohanlk χα betätigen, dann wird dieselbe gewöhnlich so besohädigt, dafl sie unbrauchbar wird·In the case of the known pivot pins with screwed-on tips, it is very common for the mine guide channel to go through clogged at the tip by broken parts of the mine " Is tried in a solohon trap the Torsohttbmeohanlk Press χα, then it becomes common so damaged that it becomes unusable
Um diesen Nachteil zu vermeiden, wird gemäß der naolist eh end beschriebenen Neuerung vorgeschlagen, die Spitze mit dem Drehstift-Schaft nicht zu verschrauben, sondern durch Pressitz, Gleit- oder Schiebesitz lösbar zu verbinden· Die Spitze wird also in den Schaft nicht mehr eingeschraubt, sondern bloß eingestehet. Ist der Minenleitkanal in einer solchen Steokspitae verstopft, und wird die Vorsohubmeohanik dennooh betätigt, dann wird die Spitze durch die Meohanik aus dem Drehstift-Schaft einfaoh herausgestoßen, sodaß die Meohanik unbeschädigt bleibt.According to the naolist, in order to avoid this disadvantage Eh end described innovation proposed not to screw the tip to the pivot pin shaft, but to be detachably connected by press fit, slide fit or slide fit The point is no longer screwed into the shaft, but merely admitted. Is the mine duct clogged in such a Steokspitae, and if the Vorsohubmeohanik is activated, then the tip through the Meohanik from the pivot pin shaft simply pushed out, so that the meohanics undamaged remain.
Der Entfall des Gewindes ergibt außerdem eine vereinfachte, daher verbilligte Ausführung des Drehstiftes.The omission of the thread also results in a simplified and therefore cheaper design of the pivot pin.
In beiliegender Zeichnung zeigt die Pig.l einen Drehstift der bisher üblichen Ausführung mit aufschraubbarer Spitze, während die Pig.2 einen Drehstift der neuen Ausführung mit Steokspitze zeigt· Die Spitzen sind in beiden Figuren vom Drehstift-Schaft abgenommen gezeichnet·In the accompanying drawing, the Pig.l shows a rotary pen the usual version with screw-on Tip, while the Pig.2 shows a new version of the rotating pen with a Steok tip · The tips are drawn removed from the pivot pin shaft in both figures
