Absperrvorrichtung für Gasleitungen.Shut-off device for gas pipes.

Patentiert im Deutschen Reiche vom 19. Dezember 1905 ab.Patented in the German Empire on December 19, 1905.

Der Gegenstand vorliegender Erfindung ist eine selbsttätig arbeitende Gasleitung, welche sich dadurch auszeichnet, daß die Leitung, falls kein Gas gebraucht wird, im Keller kurz hinter dem Gasmesser gegen diesen abgesperrt ist und mit einem ins Freie führenden Lüftungsrohr in Verbindung gebracht ist, wodurch sich die Leitung vollständig entleeren kann, so daß, falls durch Unachtsamkeit ein Gashahn an einem Licht, Ofen öder dergl. aufbleiben sollte, kein Gas entweichen kann. Außerdem ist die Gasleitung von jedem Stockwerk aus kontrollierbar, so daß man genau feststellen kann, ob der Haupthahn im Keller beim Gasmesser offen oder geschlossen ist.The subject of the present invention is an automatically operating gas line which is characterized by the fact that the pipe, if no gas is needed, is in the basement just behind the gas meter is locked against this and with a leading into the open Ventilation pipe is connected, whereby the line can empty completely, so that, if by carelessness a gas tap on a light, stove or the like should remain open, no gas should escape can. In addition, the gas line can be controlled from every floor, see above that you can determine exactly whether the main tap in the cellar by the gas meter is open or closed.

Auf der Zeichnung ist der Gegenstand der Erfindung beispielsweise dargestellt, und zwar zeigt sie eine Gasleitung für zwei Stockwerke. Kurz hinter dem Gasmesser α ist in die Hauptleitung b ein Dreiweghahn d eingebaut, der durch einen Gewichtshebel f bewegt wird. Durch diesen Dreiweghahn d ist die Hauptleitung b für den Gaszutritt von b¹ oder dem Gasmesser α aus für gewöhnlich geschlossen, während sie mit dem ins Freie führenden und- hier offenen Lüftungsrohr h in Verbindung steht. In die Abzweigleitungen c eines jeden Stockwerkes ist kurz hinter dem Austritt aus der Hauptleitung b je ein Hahn i, eingebaut, der, falls auf dem Stockwerk kein· Gas gebraucht wird, geschlossen ist und der. durch einen doppelarmigen Hebel k bewegt wird, dessen einer Arm eine Sperrklinke / trägt, die in Löcher des Sperrbügels m eingreift und zur Feststellung des Hahnes dient, während der andere Arm in eine mit einem langen Schlitz versehene, in die zu dem Gewichtshebel f des im Keller angeordneten Dreiweg- hahnes d führende Zugleitung ρ eingeschaltete öse 0 eingreift. Kurz hinter dem Hahn i ist auf jedem Stockwerk eine Lampe η vorgesehen , die unmittelbar von der Abzweigleitung c aus gespeist wird und zweckmäßig keinen besonderen Hahn aufweist und mit einer zuverlässigen Selbstzündung versehen ist, so daß die Lampe stets brennt, sobald sich Gas in der Leitung c befindet.In the drawing, the object of the invention is shown for example, namely it shows a gas line for two floors. Shortly after the gas meter α , a three-way valve d is installed in the main line b , which is moved by a weight lever f . The main line b for the gas admission from b ¹ or the gas meter α is usually closed by this three-way valve d , while it is connected to the ventilation pipe h which leads to the outside and is open here. In the branch lines c of each floor, shortly after the outlet from the main line b , a cock i is installed which, if no gas is needed on the floor, is closed and the. is moved by a two-armed lever k , one arm of which carries a pawl / which engages in holes in the locking bracket m and is used to lock the cock, while the other arm is provided with a long slot in which to the weight lever f of the im Basement arranged three-way faucet d leading trainline ρ engaged eyelet 0 engages. Shortly after the tap i , a lamp η is provided on each floor, which is fed directly from the branch line c and expediently has no special tap and is provided with reliable self-ignition so that the lamp always burns as soon as there is gas in the line c is located.

Die Arbeitsweise der Einrichtung ist nun folgende: Soll auf dem Stockwerk 2 Gas der Leitung entnommen und gebraucht werden, so wird der Hahn i durch Drehung des doppelarmigen Hebels k zunächst geöffnet, worauf dieser mittels der Sperrklinke /, die in den Sperrbügel m eingreift, festgestellt wird. Durch die Drehung des Hebels.k, dessen einer Arm in die Öse 0 eingreift, ist gleichzeitig der Zugdraht ρ und mit diesem der Gewichtshebel / des Dreiweghahnes d hochgezogen und dieser auch gedreht worden, und zwar so, daß das Gas von b¹ und 'dem Gasmesser α her in die Hauptleitung b und von dieser durch den geöffneten Hahn i in die Abzweigleitung c eintreten kann, nachdem die Hauptleitung b gleichzeitig durch Drehung des Dreiweghahnes d gegen das ins Freie führende Lüftungsrohr h abgesperrt worden ist. Das zweckmäßig mit einer Selbstzündung versehene Licht η wird sich, sobald das Gas in die Abzweigleitung c eintritt, entzünden und wird so lange brennen,The operation of the device is as follows: If gas is to be taken from the line on floor 2 and used, the cock i is first opened by turning the double-armed lever k , whereupon it is determined by means of the pawl / which engages in the locking bracket m will. By turning the lever. k, one arm of which engages in the eyelet 0, the pull wire ρ and with it the weight lever / the three-way cock d is pulled up at the same time and this has also been turned, in such a way that the gas from b ¹ and 'the gas meter α into the Main line b and from this through the open cock i can enter the branch line c after the main line b has been shut off at the same time by turning the three-way cock d against the ventilation pipe h leading to the outside. The light η , which is expediently provided with a self-ignition, will ignite as soon as the gas enters the branch line c and will burn for as long as

as gas flows out of branch line c, since it cannot be extinguished by a special tap. It will therefore always be a reminder that the tap i in the branch line c and also the three-way tap d in the cellar by the gas meter are open. Since the eyelets o are provided with a long slot, the cock i on the floor ι has not been opened by pulling up the pull wire ρ, because the eyelet ο can move up without taking the lever k with it. If you want to use the gas on the floor ι, the lever k is turned accordingly, which in turn allows the long slot of the raised eyelet 0, and then the light η will ignite here too as soon as the gas enters the branch line c occurs. If gas is no longer required on one of the floors, the light η, which is always on when the line is open, reminds you that the tap i is closed by turning the lever k back, whereupon the light η naturally goes out immediately. If gas is then to be used on the second floor, then the lever k of the cock i, which is opened here and which is fixed by the pawl / and the locking bracket m, causes the pull wire ρ to sink under the action of the weight lever / and thus to close the Three-way valve d prevented. Rather, this can only happen when the last tap i is closed and no more gas is to be used on any floor. Then, when the three-way valve d is closed, the main line b is simultaneously brought into connection with the pipe h leading into the open air and the gas still in the line can escape through this to the open air, so that the line is completely emptied; If a tap on one of the floors is left open due to carelessness, no more gas can escape from it and an accident can be prevented. The mode of operation of the new, automatically operating gas line is, as can be seen from the above, very simple and reliable. Of course, the means used can also be replaced by other means that fulfill the same purpose. • Patent claims:
