  Sicherung gegen die Lösung der Verbindung zweier gasführender Leitungsteile bei offenen Anschlussstellen. 



   Insbesondere bei den zur Erzeugung von Acetylen verwendeten   Vorrichtungen   kommt es häufig vor, dass zwei, durch eine lösbare Verschraubung verbundene Rohre von einander getrennt werden müssen   :   um bei einer derartigen Trennung das Entweichen von Gas zu verhindern, ist 
 EMI1.1 
 
Um bei Lösung der Verbindung ein Übersehen des Sperrens der   Hähne   unmöglich zu machen, werden die Griffhebel der, zu beiden Seiten der Verbindungsstelle liegenden Hähne auf den Hahnwirbeln derart aufgekeilt, dass sie sich bei geöffneten Hähnen an die, zur Verbindungsstelle führenden   Rohrteile anlegen, und   an ihren Enden mit Schirmen versehen, welche in dieser Stellung je eine Hälfte der Verbindungsstelle überdecken,

   so dass letztere bei geöffneten Hähnen von den   Schirmen umschlossen   und nur dann   zugänglich ist, wenn   die beiden Hahnhebel in die Verschlussstellung geschwenkt worden sind. 
 EMI1.2 
 Hähnen entsprechenden Stellung zeigt. 



   Wie ans diesen Darstellungen ersichtlich, sind die beiden Leitungsteile a, a durch eine Holländerverschraubung b mit einander verbunden. 



   Um jeden Leitungsteil a vor Lösung der Holländerverschraubung b absperren zu können, ist vor dem Leitungsende ein Absperrhahn c angeordnet. 



     Die Griffhebel M.   dieser   Absperrhähne   c sind derart gestellt, dass sie bei geöffneten   Hähnen     gegen   die Anschlussstelle zu gerichtet sind. An jedem der Griffhebel m ist ein halbcylindrischer   Schirm   n angeordnet, welcher die Mutter b, des   Holländerverschlusses zur   Hälfte umgibt, so dass sie von den beiden Schalen n. n zur Gänze umfasst wird, wenn die Hähne c, c geöffnet sind. 



   Um die Holländerverschraubung zu lösen, bzw. die Mutter b durch einen   Schlüssel   erfassen zu können, müssen die beiden Griffhebel m in die. in Fig. 4 gezeigte Stellung geschwungen werden.   in welcher die Hähne c, c geschlossen sind.

  Protection against the loosening of the connection between two gas-carrying pipe parts with open connection points.



   In particular with the devices used to generate acetylene, it often happens that two pipes connected by a detachable screw connection have to be separated from one another: in order to prevent gas from escaping during such a separation
 EMI1.1
 
In order to make it impossible to overlook the locking of the taps when the connection is released, the handle levers of the taps located on both sides of the connection point are wedged on the tap vertebrae in such a way that, when the taps are open, they lie against the pipe parts leading to the connection point, provide their ends with screens, which in this position each cover half of the junction,

   so that the latter is enclosed by the screens when the taps are open and is only accessible when the two tap levers have been pivoted into the closed position.
 EMI1.2
 Shows the corresponding position of the cocks.



   As can be seen from these illustrations, the two line parts a, a are connected to one another by a Dutch screw connection b.



   In order to be able to shut off each line part a before loosening the Dutch screw connection b, a shut-off valve c is arranged in front of the end of the line.



     The handle levers M. of these shut-off cocks c are set in such a way that they are directed towards the connection point when the cocks are open. A semi-cylindrical screen n is arranged on each of the handle levers m, which half surrounds the nut b of the Dutch closure so that it is completely surrounded by the two shells n. N when the taps c, c are open.



   In order to loosen the Dutch screw connection or to be able to grasp the nut b with a key, the two handle levers m must be in the. position shown in Fig. 4 are swung. in which the taps c, c are closed.
 EMI1.3
 Connection lines made impossible.
