Die Erfindung bezieht auf einen selbstkassierenden Gasmesser und bezweckt, nach Verbrauch einer dem eingeworfenen Geldbetrage entsprechenden Gasmenge den Gasstrom von der Anschlußleitung vollständig sicher abzusperren.The invention relates to a self-collecting gas meter and aims to Consumption of an amount of gas corresponding to the amount of money thrown in the gas flow completely and safely shut off from the connection line.

Bei den bisherigen Gasselbstverkäufern wurde dieser Abschluß in der Regel vermittels einer in der Gaszuleitung angeordneten,With the previous gas self-sellers, this conclusion was usually mediated one arranged in the gas supply line,

ίο entsprechend bewegten Klappe oder eines Ventils bewirkt.ίο appropriately moved flap or one Valve causes.

Bei dem vorliegenden Gasselbstverkäufer wird dagegen das zuströmende Gas nach beendeter Lieferung hydraulisch gegen die Anschlußleitung abgeschlossen.In the present gas self-seller, however, the inflowing gas is after Completed delivery hydraulically locked against the connection line.

Auf den Zeichnungen, welche ein Ausführungsbeispiel der Erfindung darstellen, ist Fig. ι eine Vorderansicht des offenen Gasmessergehäuses bei geöffneter Gasabzugsleitung, Fig. 2 eine Seitenansicht von Fig. 1, Fig. 3 ein Schnitt nach A-B der Fig. 2 in größerem Mäßstabe, Fig. 4 eine Einzelansicht der Verschlußvorrichtung in der Offenlage, Fig. 5 dieselbe Ansicht mit durchschnittenen Verschlußröhren in der Schlußlage. Fig. 6 ist ein Schnitt nach C-D der Fig. 4 und Fig. 7 ein solcher nach E-F der Fig. 5.In the drawings which illustrate an exemplary embodiment of the invention, FIG. 1 is a front view of the open gas meter housing with the gas discharge line open, FIG. 2 is a side view of FIG. 1, FIG. 3 is a section according to AB of FIG. 2 on a larger scale, FIG 4 shows a detailed view of the closure device in the open position, FIG. 5 the same view with cut-through closure tubes in the closed position. FIG. 6 is a section according to CD in FIG. 4 and FIG. 7 is a section according to EF in FIG. 5.

Das Hauptmerkmal des Apparates bildet eine im Innern des Gasmessergehäuses a angeordnete, mit der Anschlußleitung in Verbindung stehende, oben offene Röhre b, auf welcher eine zweite Röhre c verschiebbar angeordnet ist, die an ihrem oberen Ende geschlossen und mit Schlitzen d versehen ist (Fig. 4 bis 7). Diese letztere Röhre wird durch ein geschlitztes Rohrstück e entsprechend geführt und gegen Drehung gesichert. Sie nimmt zu der Röhre b zwei bestimmte Stellungen ein, und zwar eine, in welcher sich ihre Schlitze d über der oberen Öffnung der Röhre b befinden, so daß das Innere der letzteren mit dem Innern des Gasmessergehäuses in Verbindung gebracht ist (Fig. 4), und eine, in welcher das obere geschlossene Ende der Röhre c die Röhre b oben abschließt (Fig. 5).The main feature of the apparatus is a tube b, which is arranged inside the gas meter housing a and communicates with the connection line, is open at the top and on which a second tube c is slidably arranged, which is closed at its upper end and provided with slots d (Fig. 4 to 7). This latter tube is guided accordingly through a slotted piece of tube e and secured against rotation. It assumes two specific positions relative to the tube b , namely one in which its slits d are located above the upper opening of the tube b , so that the interior of the latter is brought into communication with the interior of the gas meter housing (Fig. 4). , and one in which the upper closed end of the tube c closes the tube b at the top (Fig. 5).

Die verschiebbare Röhre c ist durch einen Hebel / mit einer senkrechten Schubstange g verbunden (Fig. 1, 4 und 5), die im Gasmessergehäuse entsprechend geführt und am oberen, aus dem Gehäuse herausragenden Ende mit einem gelenkigen Doppelhebel h i verbunden ist, dessen einer Arm i durch eine Zugstange I mit dem Münzenhebel k in Verbindung steht. Der letztere schwingt in bekannter Weise um einen Zapfen m am Münzenturme η (Fig. 2 und 3).The displaceable tube c is connected by a lever / to a vertical push rod g (Fig. 1, 4 and 5), which is guided accordingly in the gas meter housing and at the upper end protruding from the housing is connected to an articulated double lever hi , one arm of which i is connected to the coin lever k by a pull rod I. The latter oscillates in a known manner around a pin m on the coin tower η (FIGS. 2 and 3).

Der Münzenhebel k besitzt an seinem äußeren Ende einen Einschnitt 0 o. dgl. (Fig. 3) zur Aufnahme eines um einen BoI-zen q am Apparatgestell schwingbaren Gewichtshebels p, der sich außerdem mittels eines Stiftes o. dgl. r (Fig. 2) auf einen Arm 5 legt, auf dessen Welle t ein zweiter, nach unten ragender Anns sitzt. Dieser Arm wird durch einen an einer Zahnscheibe w sitzenden Daumen oder Exzenter ν bewegt. Die Zahnscheibe w wird mittels der Übertra-At its outer end, the coin lever k has an incision 0 or the like (Fig. 3) for receiving a weight lever p which can swing around a pin q on the apparatus frame and which is also moved by means of a pin or the like r (Fig. 2 ) on an arm 5, on whose shaft t sits a second, downwardly protruding Anns. This arm is moved by a thumb or eccentric ν sitting on a toothed disk w . The toothed washer w is transmitted by means of the

Claims

transmission mechanisms xy driven by the gas meter and also acts in a known manner by means of the lever \ on the money pusher 2.

The mode of operation of the device is as follows:

In the rest position, the coin lever k is swung back (dash-dotted line in Fig. 3) and the weight lever ρ influencing the same is raised somewhat by the arm s by means of the thumb ν of the toothed disk w acting on the arm u sitting on the same shaft (dash-dotted line in Fig. 2) . In this position, the vertical push rod g is in its low position, in which it closes the gas vent tube b by means of the lever / through the sliding tube c (FIGS. 5 and 7). When the slide 3 of the coin tower is coupled to the coin lever h by a coin and pressure on the slide, the coin lever is moved to the left (Fig. 3), the latter being lifted by the rod and lever connection I ih of the same with the vertical push rod g as a result, the tube c is pushed up so that its slits d come to lie over the upper opening of the gas discharge tube b (FIGS. 4 and 6). The gas flowing through the line 4 (FIG. 1) into the gas meter can then, after passing through the drum, be withdrawn through the slits d of the tube c, which are above the water level of the gas meter, through the tube b into the connection line for consumption. Due to the rotation of the toothed disc w, the means by which at the gas vent immediately commencing rotation of the gas cylinder of the transmission is effected χ y in ■ indicated in Fig. 2 arrow direction, the weight lever is ρ by thumb and lever ν u and arm s initially somewhat raised more and then completely released so that it can now fall freely into the incision ο of the coin lever k and thereby hold the same in the open position.

As soon as the amount of gas determined by the circumference of the toothed disk w has flowed out through the tubes b , the thumb ν of the toothed disk w comes into contact with the arm u again, so that by means of the arm s sitting on the same shaft, the weight lever ρ from the incision 0 of the Coin lever k is lifted out again and the latter, as a result, since the clutch has since been triggered by means of the coin in a known manner by the lever % acting on the money slide 2 and moved through the disk w , goes back into the final position. Here, by means of the rod and lever connection / ih the vertical push bar g and thus also the displaceable tube c downwards again performed so that the Zulaßöffnung d of the sleeve valve c via the c in the guide e of the sleeve valve arranged Zulaßöffnungen glides and the latter by the Tube c are covered (Fig. 5). Up to now the closure has been the same as with normal gate valves, ie in the gas space. Since in the new device, when this slide valve c falls, the inlet opening d arranged in it, while the upper opening of the discharge tube b is covered by the upper wall of the slide valve, comes under the water level, the gas seal through the inlet opening is tight d surrounding water reached respectively. secured. The seal is then no longer mechanical, ie a seal of surfaces with surfaces, but the gas is then completely sealed off from the discharge pipe b by the water level in the gas meter housing.

The transfer of motion from the coin lever k to the displaceable tube c and that from the gas drum to the disks w χ and finally the influence of the weight lever ρ by the latter can take place in any suitable manner. The pipe slide c can also be replaced by any other means that acts in a similar manner. The means specified for this purpose in the present are therefore only an exemplary embodiment and have no significant influence on the effect of the locking device per se.
