Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Im Kessel ist ein die Wandung des Flammrohres durchdringendes Rohr R eingebaut, an dessen unterem Ende sich ein durchbohrter Verschlufs V befindet. Oberhalb des letzteren sind ein oder mehrere Pfropfen P bis P2 aus Metalllegirung eingesetzt. Sie sind durch eine Stange belastet, welche ein Gewicht G trägt, wie in Fig. 1, oder, wie in Fig. 3, eine Federbelastung hat. A tube R penetrating the wall of the flame tube is installed in the boiler, at the lower end of which there is a pierced shutter V. Above the latter, one or more plugs P to P 2 made of metal alloy are inserted. They are loaded by a rod which carries a weight G , as in Fig. 1, or, as in Fig. 3, has a spring load.
Der Pfropfen ist in seiner Lage durch das Rohr R vom Dampf- und Wasserraum abgesperrt und kann eine wesentlich höhere Temperatur als das Kesselwasser nicht annehmen. Das Rohr R leitet die Wärme des Feuers dem Pfropfen zu; es wird aber nebst dem Pfropfen durch das Kesselwasser gekühlt, so lange der Wasserstand hoch genug ist. Sinkt aber der Wasserspiegel, so ist der untere Pfropfen dem Schmelzen etwas ausgesetzt, er wird bei mehr sinkendem Wasserstande schmelzen, die Stange 5 sinkt nach und setzt Dampfpfeifen oder sonstige Signale in Thätigkeit.The plug is blocked in its position by the pipe R from the steam and water space and cannot assume a significantly higher temperature than the boiler water. The pipe R conducts the heat of the fire to the plug; However, in addition to the plug, it is cooled by the boiler water as long as the water level is high enough. If, however, the water level sinks, the lower plug is somewhat exposed to melting; it will melt when the water level sinks, the rod 5 sinks and sets steam whistles or other signals into action.
Das geschmolzene Metall fliefst durch die Durchbohrung des unteren Verschlusses ab. Der zweite Pfropfen P1 hat einen höheren Schmelzpunkt; auch er wird bei tiefer gesunkenem Wasserstand schmelzen und eine zweite Alarmvorrichtung lösen, ebenso ist durch den dritten Pfropfen eine letzte Warnung einzustellen. The molten metal drains through the hole in the lower closure. The second plug P 1 has a higher melting point; it will also melt when the water level has dropped lower and trigger a second alarm device; a final warning must also be set with the third stopper.
Die Gewichtsbelastung (Fig. 1), welche beliebig hoch sein kann, functionirt ohne Reibung und ist für stationäre Kessel bestimmt, der Apparat nach Fig. 3 dagegen für Lokomotiven und Lokomobilen mit Federbelastung und Zeiger. Die Lage des Sicherheitsapparates kann in mehreren Ausführungen geändert werden, verschiedene Pfropfen können auch in mehreren Rohren andere Höhenlagen einnehmen. The weight load (Fig. 1), which can be arbitrarily high, functions without friction and is intended for stationary boilers, whereas the apparatus according to FIG. 3 is intended for locomotives and spring loaded locomotives and pointers. The location of the security apparatus can be changed in several designs, different plugs can also be in several pipes occupy different altitudes.
