Um das Herausnehmen des gespannten Verschlusses aus der Öffnung zu erleichtern, ist an dem Schraubenende ein Vierkant k vorgesehen. welcher das Lockern des Konus d von seinem Sitz in der Aussparung c erleichtert. An Stelle der mittels   Schraubenschlüssels anziehbaren   Mutter g könnte auch eine Flügelmutter mit Vorteil verwendet werden. 



   Fig. 3 zeigt eine etwas andere Ausführung des Verschlusses,   u.   zw. ist dort   der Konus   nicht als Kopf der Schraube ausgebildet, sondern bildet mit der Unterlagscheibe i ein Ganzes. 



  Den Gegendruck nimmt in diesem Fall beim Anziehen der   : Mutter ! I die   als Kopf der Schraube e ausgeführte Scheibe   In   auf.

 des Verschlusses gegen das Rohrinnere ist aber eine ebenso gute und sichere. 



   Der reichliche Abmessungen aufweisende Vollkonus a bewirkt ein starkes Auseinanderpressen des betreffenden Teiles des Gummiringes gegen die Rohrwandung i, während die als Widerlager dienende Platte i bzw. der flache Kopf m des Bolzens    ein Ausweichen des   Gummistopfens in Richtung des Druckes verhindert, so dass der wesentlich grössere Durchmesser als der Bolzen e aufweisende   Vollkonus d   gleichzeitig ein Zusammenpressen des   Gummiringes   in axialer Richtung gewährleistet. ohne dass der Stopfen irgendwie beschädigt wird.

 lediglich seine Zugelastizität durch radial auf ihn einwirkende Kräfte auszunutzen. Es ist dann besser, ihn vorzugsweise auf Druck zu beanspruchen, weil bei der letzteren Beanspruchung sein innerer Zusammenhang nicht leiden kann. 



   Neben seiner ausgesprochenen Einfachheit, also derben konstruktiven Ausgestaltung, zeigt der neue Verschluss die Eigenart, dass bei ihm der Gummiring ausser in radialer   Richtung   auch in axialer Richtung einer Pressung ausgesetzt ist. In demselben Masse wie der Ring axial gepresst wird, braucht er radial nicht gedehnt zu werden. In Anbetracht des Umstandes. dass Gummi im Laufe der Zeit seine innere Beschaffenheit ändert, ist dies praktisch von Bedeutung.

A square k is provided at the end of the screw to make it easier to remove the cocked closure from the opening. which facilitates the loosening of the cone d from its seat in the recess c. Instead of the nut g which can be tightened by means of a wrench, a wing nut could also be used with advantage.



   Fig. 3 shows a slightly different embodiment of the closure, u. between the cone there is not designed as the head of the screw, but forms a whole with the washer i.



  In this case, the counter pressure decreases when tightening the: nut! I the washer In designed as the head of screw e.

 the closure against the inside of the pipe is just as good and safe.



   The full cone a, which has ample dimensions, causes the relevant part of the rubber ring to be strongly pressed apart against the pipe wall i, while the plate i serving as an abutment or the flat head m of the bolt prevents the rubber stopper from deflecting in the direction of the pressure, so that the much larger one Diameter than the full cone d having the bolt e at the same time ensures a compression of the rubber ring in the axial direction. without damaging the plug in any way.

 only to use its tensile elasticity by forces acting radially on it. It is then better to stress it, preferably under pressure, because the latter stress does not affect its inner coherence.



   In addition to its pronounced simplicity, that is to say a crude structural design, the new closure has the peculiarity that the rubber ring is subjected to pressure not only in the radial direction but also in the axial direction. To the same extent as the ring is axially compressed, it does not need to be expanded radially. In view of the fact. That rubber changes its internal structure over time, this is of practical importance.
