Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
An seiner Hülse besitzt der Zapfhahn, Fig. 1, seitlich einen kleinen, mit Gewinde versehenen hohlen Ansatz a, welcher zur Befestigung* eines Rohres eventuell Schlauches dient. Diesem entsprechend, besitzt der Hahnkomis eine Nuth c, welche bei geöffnetem Hahn jenem Ansatz gegenübersteht und so die Fortsetzung seiner Höhlung bildet. Sowohl Ansatz als auch Nuth sind noch unterhalb der Bohrung des Hahnes angeordnet, so dafs in keinem Fall eine Verbindung des Hahninnern mit der Atmosphäre durch diesen Ansatz oder diese Nuth herbeigeführt wird.On the side of its sleeve, the tap, FIG. 1, has a small, threaded, hollow attachment a, which may be used to attach a pipe to a hose. Corresponding to this, the Hahnkomis has a groove c which, when the cock is open, faces that approach and thus forms the continuation of its cavity. Both the approach and the groove are arranged below the bore of the tap, so that in no case a connection between the interior of the tap and the atmosphere is brought about by this approach or this groove.
Erwähnte Nuth mündet in einen Ausschnitt b der Unterlagscheibe d, wie dieses in Fig. 3 und 4 zu ersehen.Mentioned groove opens into a section b of the washer d, as can be seen in FIGS. 3 and 4.
Ist der Zapfhahn in das Fafs eingeschraubt, so wird vermittelst eines Schlauches f und eines hohlen Spundes g die Communication zwischen dem erwähnten Ansatz und dem Fafsinnern hergestellt. Wird nun der Hahn geöffnet und in die Stellung Fig. 2 gedreht, so fliefst das Bier durch die Hahnbohrung ungehindert aus, während zugleich Luft durch die Oeffnung b der Unterlagscheibe d, Nuth c, Ansatz a, Schlauch / und Spund g in dem Mafse, als Bier durch den Hahn abfliefst, in das Fafsinnere tritt.If the tap is screwed into the barrel, the communication between the mentioned attachment and the inside of the barrel is established by means of a hose f and a hollow bung g. If the tap is now opened and turned to the position Fig. 2, the beer flows out unhindered through the tap bore, while at the same time air through the opening b of the washer d, groove c, attachment a, hose / and bung g to the extent that when beer drains through the tap, enters the inside of the barrel.
Schliefst man nun den Hahn, so wird zunächst durch den Hahnkegel die Bohrung des Ansatzes α verdeckt; es kann mithin keine frische atmosphärische Luft in das Fafsinnere hinein- und keine Kohlensäure aus letzterem heraustreten; das Bier bleibt also stets frisch und kohlensäurehaltig.If you now close the tap, the bore of the shoulder α is initially covered by the tap cone; Consequently, no fresh atmospheric air can enter the interior of the barrel and no carbonic acid can escape from the latter; so the beer always stays fresh and carbonated.
Um nun weiter das Nachtropfen beim Schliefsen des Hahnes zu vermeiden, ist noch eine zweite Nuth c1 am breiten Ende des Konus angebracht, welche bei geschlossenem Hahn eine Communication der atmosphärischen Luft und des Hahninnern vor dem Hahnkegel herstellt, so dafs die nach dem Abzapfen im Hahn stehengebliebene Flüssigkeitssäule durch die von oben her eintretende Luft verdrängt wird und durch die Hahnöffnung abfliefst. An Stelle der Nuth in der Oberfläche des Hahnkegels können auch entsprechende Bohrungen treten.In order to further prevent dripping when the tap is closed, a second groove c 1 is attached to the wide end of the cone, which, when the tap is closed, establishes a communication between the atmospheric air and the inside of the tap in front of the tap cone, so that after the tapping in The liquid column that has stopped from the tap is displaced by the air entering from above and drains through the tap opening. In place of the groove in the surface of the tap cone, corresponding bores can also be used.
