Vorrichtung zum Anzeigen des Mangels an Kohle im Schachte von Füllöfen mit in den
Schacht hineinragender, bei gefülltem Schacht niedergedrückter Pendelklappe.
Die Erfindung betrifft eine Vorrichtung bei Füllöfen, die ausserhalb des Ofenmantels selbsttätig anzeigt, dass der Brennstoffvorrat im Füllschacht zur Neige geht. Dies wird dadurch erreicht, dass eine an der Innenwand des unteren Füllschachtendes drehbar ge-

beschicktem FüUschacht durch den Druck der Kohle an die Innenwand des Schachtes legt, unter Einwirkung eines Gewichtshebels aber einwärts ausschlägt, sobald die Kohle unter die Unterkante der Klappe gesunken ist, wobei gleichzeitig eine an dem nach oben reichenden Arm des Gewichtshebels angebrachte Zeigerplatte sich durch einen in dem Ofenmantel vorgesehenen Schlitz nach aussen verschiebt und so die Entleerung des Füll- schachtes anzeigt.
Die neue Anzeigevorrichtung ist in der Zeichnung dargestellt. Fig. 1 zeigt einen Schnitt des Ofens bei geflilltem Füllschacht Fig. 2 einen Schnitt bei geleertem Füllschacht undvorgeschobenerZeigerplatte.
Die Vorrichtung besteht aus einer Klappe a, welche zwischen zwei Augen c gelenkig gelagert ist und den Füllschacht in einem Schlitz (/so durchsetzt, dass sie an dessen Innenfläche anliegt. In einiger Entfernung von dem Drchzapfen f der Klappe a ist an

Device for displaying the lack of coal in the shaft of filling furnaces with in the
The pendulum flap protrudes into the shaft and is depressed when the shaft is full.
The invention relates to a device in filling furnaces which automatically indicates outside the furnace shell that the fuel supply in the filling shaft is running out. This is achieved in that a rotatable on the inner wall of the lower hopper end
EMI1.2
FüUschacht loaded FüUschacht by the pressure of the coal against the inner wall of the shaft, but under the action of a weight lever deflects inward as soon as the coal has sunk below the lower edge of the flap, while at the same time a pointer plate attached to the arm of the weight lever reaching upwards moves through an in the slot provided in the furnace shell to the outside, thus indicating that the filling chute is empty.
The new display device is shown in the drawing. Fig. 1 shows a section of the furnace with the hopper filled. Fig. 2 shows a section with the hopper emptied and the pointer plate advanced.
The device consists of a flap a, which is articulated between two eyes c and penetrates the filling chute in a slot (/ so that it rests on its inner surface. Some distance from the pivot f of the flap a is on

on the inner wall of the filling chute and push the pin k located on the lever arm h outwards, so that the pointer plate n attached to the lever arm l is pulled inwards. The coal sinks to below the lower edge of the plate. so the latter is represented by the pin k
EMI1.4
the upper arm extends so far outwards that the pointer plate pushes through the slot and the inscription on it becomes visible.
As soon as it has been refilled, the flap rests on the filling chute and the pointer plate moves back again.
