Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Vorliegende Neuerung hat zum Gegenstande die Anordnung der beiden Selbstschlufsventile in den oberen, entsprechend ausgebohrten Enden zweier im oberen und unteren Stutzen des Wasserstandszeigers gelagerten Schrauben- . spindeln mit steiler Steigung. Vermöge dieser Anordnung der Ventile werden andere ■ Abschlufsorgane zwischen Glas und Kessel überflüssig, woraus einfachere Handhabung und leichteres Gewicht des Apparates resultirt.The subject of the present innovation is the arrangement of the two self-closing valves in the upper, appropriately drilled ends of two in the upper and lower nozzle of the water level pointer mounted screw. spindles with a steep incline. Fortune this Arrangement of the valves, other closing devices ■ between the glass and the boiler are superfluous, which results in easier handling and lighter weight of the apparatus.

Auf beiliegender Zeichnung veranschaulicht Fig. ι die Vorderansicht mit zwei Verticalschnitten durch beide Stutzen des Apparates und Fig. 2 die Seitenansicht desselben.On the accompanying drawing, Fig. Ι illustrates the front view with two vertical sections through both nozzles of the apparatus and FIG. 2 shows the side view of the same.

Die Schraubenspindeln s sl sind, zur Längsachse des Glases geneigt, in den Gehäusen g g1, deren Verschlüsse u ul ihnen als Muttern dienen, gelagert. Die in den Gehäusen befindlichen Enden der Spindeln haben Ausbohrungen, in welchen sich die Ventile ν V1 führen, während die aufserhalb der Gehäuse befindlichen Enden mit Handgriffen h H1 versehen sind. Die Bewegungsfreiheit der Ventile ν νx ist dadurch begrenzt, dafs quer zur Längsachse der betreffenden Ausbohrungen Stifte t eingesetzt sind, welche sich gegen Ansätze des Ventilschaftes legen, wenn die Schraubenspindeln herausgeschraubt werden. Für den Handgriff/? kommen drei Lagen in Betracht. In der Stellung ι schliefst Ventil ν beim Bruch des Glases selbstthätig ab. Durch Umlegen des Handgriffes in die Stellung 2 wird ein Abschlufs bei normalem Betrieb erzielt, während in Stellung 3 das Glas mit Dampf durchgeblasen werden kann. In gleicher Weise wird das untere Ventil gehandhabt. Mittelst Drehung der Handgriffe um i8o° nehmen die Ventile die gekennzeichneten Lagen der Reihe nach, ein. Nach stattgehabtem Druckausgleich in Stellung 1 fallen die Ventile vermöge ihrer eigenen Schwere in die ursprüngliche Lage zurück. Um dem Dampfe bezw. Wasser besseren Zutritt zu gestatten, sind am Grunde der Bohrungen in den Spindeln seitliche Löcher I vorgesehen.The screw spindles ss l , inclined to the longitudinal axis of the glass, are mounted in the housings gg 1 , the closures of which uu l serve as nuts for them. The ends of the spindles located in the housings have bores in which the valves ν V 1 are guided, while the ends located outside the housing are provided with handles h H 1 . The freedom of movement of the valves ν ν x is limited by the fact that pins t are inserted transversely to the longitudinal axis of the relevant bores, which are positioned against the shoulders of the valve stem when the screw spindles are unscrewed. For the handle /? three layers come into consideration. In position ι, valve ν closes automatically when the glass breaks. By moving the handle to position 2, a conclusion is achieved during normal operation, while in position 3 the glass can be blown with steam. The lower valve is handled in the same way. If you turn the handles by 180 °, the valves will take up the marked positions one after the other. After pressure equalization has taken place in position 1, the valves fall back into their original position due to their own gravity. To the steam respectively. Lateral holes I are provided at the bottom of the holes in the spindles to allow better access to water.

Patent-Anspruch:Patent claim: An Wasserstandszeigern die Anordnung der quer vor den Kanälen der Ventilstutzen g geneigt zur Achse des Glases gelagerten und das Durchstofsen der Kanäle in gerader Richtung gestattenden Schraubenspindeln s in beweglicher Verbindung mit selbstthätig schliefsenden Ventilen v, welche bei Drehung der Handgriffe h um etwa i8o° in jeder der beiden Endstellungen festgestellt. werden, während dieselben in der Mittelstellung den Kanal bei unterbrochenem Spannungsausgleich selbstthätig schliefsen und bei wieder eintretendem Spannungsausgleich durch ihre eigene Schwere öffnen. On water level indicators, the arrangement of the screw spindles s , which are inclined transversely in front of the channels of the valve stubs g to the axis of the glass and allow the channels to pass through in a straight direction, in movable connection with automatically closing valves v, which when the handles h are rotated by about 180 ° in each case of the two end positions determined. while in the middle position they close the channel automatically when the tension equalization is interrupted and open when the tension equalization occurs again due to their own gravity.
