Vorrichtung zur Absperrung der Pressluftleitung bei Feuerungen während der Beschickung.
Vorliegende Erfindung bezieht sich auf eine Einrichtung an Feuerungsanlagen, durch welche ein Öffnen der Feuertür während des Einströmens von Pressluft in die Feuerung dadurch verhindert wird, dass die Feuertür nur dann geöffnet werden kann, wenn die Pressluftleitung abgesperrt ist.
In der Zeichnung ist die bezeichnete Einrichtung in Fig. 1 in Ansicht und in Fig. 2 im Grundriss dargestellt. In das in das Feuergeschränke mündende Rohr a, durch welches von einem Ventilator vorgewärmte Luft eingeblasen wird, ist eine Drosselklappe b eingeschaltet, welche zu einer in Lagern c ruhenden, mittels eines Handgriffes d'zu betätigenden Welle d ausgebildet ist. Das auf letzterer aufgekeilte Kegelrad e steht in Eingriff mit einem Kegelrad/', welches an dem Ende der Welle 9 befestigt ist, die ober-

Device to shut off the compressed air line in the case of furnaces during charging.
The present invention relates to a device in firing systems by means of which opening of the fire door while compressed air is flowing into the furnace is prevented in that the fire door can only be opened when the compressed air line is shut off.
In the drawing, the designated device is shown in Fig. 1 in view and in Fig. 2 in plan. A throttle valve b is switched on into the pipe a, which opens into the fire cabinets and through which preheated air is blown by a fan, which is designed as a shaft d resting in bearings c and operated by means of a handle d. The bevel gear e keyed onto the latter is in engagement with a bevel gear / 'which is attached to the end of the shaft 9, the upper

required to close the throttle valve first, which is done by rotating the shaft d accordingly.
When the shaft d is rotated, the bevel gears e, f also cause the shaft g to rotate and the thumb k is lifted off the fire door h so that

After closing the fire door, in order to let compressed air into the furnace again, the throttle valve & is brought into its first position, the thumb k again resting against the fire door and making it impossible to open it.
