Description
Sicherheits-Ablaßschraube für nasse Gasmesser Bekanntlich bedeutet sowohl das unbefugte Abschrauben der Ablaßschraube an nassen Gasmessern überhaupt als auch das versehentliche Unterlassen des Wiederhineinschraubens seitens des den Messer kontrollierenden und. bedienenden Mannes eine Gefahr. Es sind deshalb schon verschiedene Sicherheitsvorrichtungen vorgeschlagen worden, die beide Gefahrenquellen unmöglich machen sollen. Vorliegende Erfindung besteht nun in der durch die Ansprüche gekennzeichneten und nachstehend näher erläuterten neuen Anordnung, die demselben Zwecke dienen soll.Safety drain plug for wet gas meters is known to mean both the unauthorized unscrewing of the drain plug on wet gas knives at all as well as the inadvertent failure to screw in again on the part of the Knife controlling and. man serving a danger. It is therefore already Various safety devices have been proposed to address both sources of danger to make impossible. The present invention now consists in that defined by the claims marked and explained in more detail below new arrangement, the same Purposes.
Die Erfindung ist auf der Zeichnung in zwei Abbildungen. dargestellt, von denen Abb. i einen senkrechten Schnitt der ganzen Vorrichtung und Abb. 2 einen Schnitt durch den Kopf der Ablaßschraube zeigt.The invention is on the drawing in two figures. shown, of which Fig. i is a vertical section of the entire device and Fig. 2 is a Shows section through the head of the drain plug.
Die Verschlußschraube hat einen Kopf a und eine an sich bekannte, drehbar auf diesem Kopf sitzende Kappe b, die das Drehen der Schraube von Hand oder mittels einer gewöhnlichen Zange verhindert. In die Stirnseite des Kopfes b ist eine Nut i eingedreht, durch die ein in den Kopf eingebrachter Stift ä quer hindurchgeht. In diese Nut paßt das Ende eines Steckrohrschlüssels c mit Ausnehmungen entsprechend dem Querstift g. Im Innern des Rohres dieses Schlüssels liegen Federn f mit Nasen d, die in die ringförmige, zwischen dem Stirnende des Kopfes b und dem vorstehenden Rand h der Kappe b gebildete Öffnung beim Aufstecken des Schlüssels einspringen und daher die abgenommene Schraube in an sich sonst allgemein bekannter Weise am Schlüssel festhalten. Erst beim Andrücken der Knöpfe e kann die Schraube vom Schlüssel abgelöst werden.The locking screw has a head a and a known per se, rotatably seated on this head cap b, which prevents the screw from being turned by hand or by means of ordinary pliers. A groove i is screwed into the end face of the head b , through which a pin inserted in the head a passes transversely. The end of a socket wrench c with recesses corresponding to the cross pin g fits into this groove. Inside the tube of this key are springs f with lugs d, which jump into the ring-shaped opening formed between the front end of the head b and the protruding edge h of the cap b when the key is put on and therefore the removed screw is otherwise generally known Way to hold on to the key. The screw can only be removed from the key when the buttons e are pressed.
