Patentirt im Deutschen Reiche vom 24. Januar 1886 ab.Patented in the German Empire on January 24th, 1886.
Der Mannlochdeckel α, Fig. 1 und 2, setzt sich mit seinem Rande auf die Dichtungsfläche des Gehäuses b und wird angedrückt durch einen Bügel c, welcher um den Bolzen d an dem einen Ende drehbar ist und den Mannlochdeckel in der Mitte fafst.The manhole cover α, Fig. 1 and 2, sits with its edge on the sealing surface of the housing b and is pressed by a bracket c, which is rotatable about the bolt d at one end and the manhole cover in the middle.
An dem anderen Ende des Bügels c befindet sich die Vorrichtung zum Feststellen und Anpressen des Bügels. Dieselbe besteht in einem Doppelhebel e e1, welcher um einen Bolzen f am Kopfende des Bügels drehbar ist. Das Ende e des Hebels ist als Haken gestaltet und greift unter einen am Mundstück befestigten Bolzen g. Das andere Ende e1 des Hebels trägt einen Kopf mit Gewinde, durch welchen die Schraube h geht. Mit dieser Schraube wird der Bügel angeprefst. Das Loch für den Bolzen / ist länglich erweitert, um dem Bügel die beim Anziehen der Schraube nöthige Bewegung zu gestatten.At the other end of the bracket c is the device for locking and pressing the bracket. The same consists of a double lever e e 1 , which is rotatable about a bolt f at the head end of the bracket. The end e of the lever is designed as a hook and engages under a bolt g attached to the mouthpiece. The other end e 1 of the lever has a threaded head through which the screw h passes. The bracket is pressed on with this screw. The hole for the bolt / is elongated to allow the bracket to move when the screw is tightened.
Zum Lösen des Bügels wird die Schraube h zurück- und dann der Doppelhebel um den Bolzen f so weit seitlich gedreht, dafs der Haken frei wird. Der Bügel kann nun zurückgeschlagen werden.To loosen the bracket, the screw h is turned back and then the double lever is turned sideways around the bolt f so far that the hook is free. The bracket can now be turned back.
Die seitliche Drehung des Doppelhebels ist durch zwei an demselben angebrachte, abgerundete Knaggen begrenzt, welche sich seitlich neben dem Bügel anlegen.The lateral rotation of the double lever is rounded off by two attached to it Latches limited, which lay on the side next to the bracket.
