Description
. Wird ein biegsames Rohr an Stelle einer Stopfbüchse derart angewendet, daß bei der auszuführenden Bewegung eine Verlängerung" oder Verkürzung der Sceletiachse des biegsamen Rohres eintritt, so hat diese Anordnung den doppelten Ubelstand, daß das Rohr infolge dieser Beanspruchung leicht bricht, also nur geringe Dauerhaftigkeit besitzt, und daß außerdem die Beweglichkeit des Rohres eine verhältnismäßig sehr geringe ist. Diese Übelständc werden durch die Erfindung des, Hauptpatents 118153 zum größten Teil beseitigt, indem die Anwendung des biegsamen Rohres derart erfolgt, daß dieses im wesent-. Will be a flexible pipe instead of a Stuffing box used in such a way that an extension " or shortening of the sceleti axis of the flexible tube occurs, this arrangement has the double disadvantage that the tube as a result of this stress breaks easily, so has only low durability, and that also the mobility of the tube is relatively very low. These Inconsistencies are largely eliminated by the invention of, main patent 118153 by the application of the flexible Tube takes place in such a way that this essentially
»5 liehen nur auf Biegung, nicht aber auf Zug oder Druck . beansprucht wird. Die Beweglichkeit dieses Rohres ist erheblich größer, 'dementsprechend auch seine Dauerhaftigkeit. Um indessen noch größere Dauerhaftigkeit zu erzielen und Brüche des biegsamen Rohres nahezu auszuschließen, wird gemäß vorliegender Erfindung an Stelle des bei dem Gegen-*, stände des Hauptpatents angewendeten gekrümmten Rohres ein gerades, im Ruhe-, zustande ungespanntes Rohr verwendet, das also nicht, wie bei der Ausführung nach dem Hauptpatent, schon im Ruhezustande einer -Beanspruchung unterworfen ist.»5 borrowed only by bending, but not by pulling or pushing. is claimed. The mobility this pipe is considerably larger, so is its durability. However, in order to achieve even greater durability and break the flexible pipe can almost be ruled out, according to the present invention in place of the opposite *, of the main patent applied curved pipe a straight, in rest, unstressed tube is used, which is not the case with the execution according to the main patent, already at rest is subject to stress.
Damit dieses gerade Rohstück ebenso wie bei dem Gegenstande des Hauptpatents für die auszuführende Bewegung nur auf Biegung, .nicht aber auf Zug oder Druck beansprucht werde, muß die Drehachse für den Hebel etwa in die Mitte zwischen den Rohrenden1 verlegt werden. Um dies zu ermöglichen, 35 wird der Hebel gabelförmig gestaltet und in einer entsprechenden Gabel des festen Körpers gelagert.So that this straight blank just like the subject of the main patent for the movement to be performed is only subjected to bending, but not to tension or compression, the axis of rotation for the lever must be relocated approximately in the middle between the pipe ends 1. In order to make this possible, 35 the lever is fork-shaped and mounted in a corresponding fork of the fixed body.
