PATENTAMT.PATENT OFFICE.
Die in Fig. 1, 2 und 3 der Zeichnung dargestellte Sicherheitsvorrichtung für Dampfkessel mit niedrigem Druck besteht ausThe safety device for steam boilers shown in FIGS. 1, 2 and 3 of the drawing with low pressure consists of
ι. dem feststehenden doppelwandigen Gefäfs A, dessen äufserer Raum .A1 oben durch Oeffnungen e e oder e, e, und eine beliebige Rohrleitung mit dem Dampfkessel verbunden wird, während er unten mit dem inneren offenen Raum A2 communicirt,ι. the fixed double-walled vessel A, the outer space A 1 of which is connected to the steam boiler at the top by openings ee or e, e, and any pipe, while below it communicates with the inner open space A 2,
2. dem in A2 senkrecht verschiebbaren, offenen, einfachen oder doppelwandigen Hohlkolben B, welcher in der Pfeilrichtung beliebig durch Federn oder mittelst Schnur bezw. Kette, Rollen oder Hebel durch ein Gewicht ausbalancirt und mit den beliebigen Zugregelungsorganen des Dampfkessels verbunden werden kann, und2. the vertically displaceable in A 2 , open, single or double-walled hollow piston B, which respectively in the direction of the arrow by springs or by means of cord. Chain, rollers or levers balanced by a weight and can be connected to any draft control elements of the steam boiler, and
3. dem in B befindlichen, hohlen oder massiven Kolben C, dessen beliebig geführte Stange D in der Pfeilrichtung direct oder durch Zwischentheile auf ein Sicherheitsventil mit Alarmvorrichtung einwirken kann. Der Kolben C kann auch durch ein geschlossenes Rohr ersetzt werden.3. The hollow or massive piston C located in B , whose rod D , which can be guided in any direction, can act in the direction of the arrow directly or through intermediate parts on a safety valve with an alarm device. The piston C can also be replaced by a closed tube.
Der Hohlkolben B kann durch Anbringen einer Scala an seiner Aufsenwandung gleichzeitig zum Messen des Kesseldampfdruckes dienen. Das Gefäfs A wird zum Theil mit Quecksilber und der übrige freie Raum von A1 mit Wasser oder einer anderen Flüssigkeit gefüllt.The hollow piston B can also be used to measure the boiler steam pressure by attaching a scale to its outer wall. The vessel A is partly filled with mercury and the rest of the free space of A 1 with water or some other liquid.
Bei der in Fig. 4 dargestellten Abänderung der Sicherheitsvorrichtung sind B und C durch ein mit dem Boden des Gefäfses A fest verbundenes Rohr E getrennt, welches an seinem unteren Ende mit einer oder mehreren Oeffnungen versehen ist, und dessen oberer Theil mit dem Gehäuse eines Sicherheitsventils des Dampfkessels fest verbunden werden kann. Der Zapfen F dient zur theilweisen Befestigung des Apparates. Die Wirkungsweise ist dieselbe, wie sie Fig. 2 darstellt.In the modification of the safety device shown in Fig. 4, B and C are separated by a tube E firmly connected to the bottom of the vessel A , which is provided with one or more openings at its lower end, and its upper part with the housing of a safety valve of the steam boiler can be firmly connected. The pin F is used to partially secure the apparatus. The mode of operation is the same as that shown in FIG.
