Description
Die Verbesserung am Schmelzofen besteht in der Anordnung einer Schmelzlampe, welche zusammengesetzt ist aus dem Dochtbehälter A, dem Petroleumbehälter B und dessen doppelarmigen Träger C. The improvement on the melting furnace consists in the arrangement of a melting lamp, which is composed of the wick container A, the petroleum container B and its double-armed carrier C.
Der Raum c enthält den Docht, dessen obere Fläche mit einer Lage Asbestpulver bedeckt wird. Der ringförmige Kanal d bezweckt, eine völlig gleichmäfsige Tränkung des Dochtes herbeizuführen. Der ringförmige, mit einem horizontalen Ansatz versehene, von unten einzuführende Schutzschirm e f dient dazu, den Dochtbehälter c vor zu starker Erwärmung durch den Fangtiegel k vermittelst des Hohlraumes / zu schützen. The space c contains the wick, the upper surface of which is covered with a layer of asbestos powder. The purpose of the annular channel d is to bring about a completely uniform impregnation of the wick. The annular protective screen ef , which is provided with a horizontal extension and is to be introduced from below, serves to protect the wick container c from excessive heating by the collecting crucible k by means of the cavity /.
Der Ansatzring am Fangtiegel (Schnitt a-l>) ist mit Luftlöchern versehen, die mit denjenigen des darunterliegenden Ansatzes h correspondireri und durch eine Rotation des Fangtiegels, hervorgebracht durch eine in das viereckige Loch m eingreifende Spindel, sich abwechselnd öffnen oder schliefsen, welche Einrichtung eine Regulirung der inneren Luftzuführung während des Schmelzens ohne Störung ermöglicht und dadurch zur Erhöhung der Temperatur beiträgt; g ist ein Rohransatz, der mit einem ebensolchen des Behälters B durch Gummischlauch verbunden wird.The attachment ring on the crucible (section al>) is provided with air holes which correspond to those of the attachment h underneath and which open or close alternately by a rotation of the crucible, brought about by a spindle engaging the square hole m , which means a regulation allows the internal air supply during melting without disturbance and thereby contributes to the increase in temperature; g is a pipe socket which is connected to a similar one of the container B by means of a rubber hose.
Der doppelarmige, auf das Rohr g aufschiebbare Träger C, dessen beide Enden mit an den Enden umgebogenen, den Träger kreuzenden Stäben versehen sind, ist in seinem oberen Theil zur Aufnahme des Petroleumbehälters während des Schmelzens bestimmt, welch letzterer nach Beendigung desselben auf den unteren Arm gestellt wird, wodurch ein Zurücklaufen des Petroleums aus c nach B bewirkt und die Nachdunstung des Petroleums auf ein Geringes reducirt wird. Auch die bei d schräg nach unten sich erweiternde und so vom Wärmecentrum der Lampe, dem Fangtiegel, sich entfernende Wandung des Dochtbehälters trägt zur geringeren Erwärmung und verminderter Brennstoffnachdunstung bei.The two-armed support C, which can be pushed onto the tube g , both ends of which are provided with bent-over rods crossing the support, is designed in its upper part to receive the petroleum container during melting, the latter on the lower arm after completion of the same is set, causing the petroleum to run back from C to B and the subsequent evaporation of the petroleum is reduced to a low level. The wall of the wick container, which widens obliquely downwards at d and thus moves away from the heat center of the lamp, the catching crucible, also contributes to less heating and less fuel evaporation.
Durch Entfernung des Dochtes aus C und Einbringen eines ringförmigen, siebartig durch·1 löcherten Bleches, das mit groben Drehspänen bedeckt wird, kann zum Heizen dieser Schmelzlampe mit gleichem Erfolge, wenn auch mit gröfseren Kosten, Leuchtgas verwendet werden.By removing the wick from C and inserting a ring-shaped, sieve-like sheet perforated through 1 , which is covered with coarse turnings, illuminating gas can be used to heat this melting lamp with the same success, albeit at greater cost.
