Schalter, wie Hüpfer u. dgl., werden vielfach in sogenannten Funkenkaminen eingebaut, um ihre Umgebung gegen die schädlichen Wirkungen des beim öffnen entstehenden Funkens zu beschützen. DiIe Kamine bestehen in der Regel aus Seitenwänden und an diesen angesetzten Kaminplatten. Die Kaminplatten werden auswechselbar angeordnet/ so daß sie nach ihrer Zerstörung durch dieSwitches such as hops and the like are often built into so-called spark chimneys, to protect their surroundings against the harmful effects of opening To protect spark. The chimneys usually consist of side walls and on these attached firebacks. The firebacks are arranged interchangeably / so that after their destruction by the
ίο Funken durch neue Platten ersetzt werden können. Nach der Erfindung sollen nun diese Kaminplatten ein auswechselbares Stück aus schwer brennbarem Material an der Stelle erhalten, die durch den Funken zerstört wird.ίο sparks are replaced with new plates can. According to the invention, these firebacks should now be made from a replaceable piece flame-retardant material at the point that will be destroyed by the spark.
Es braucht dann nicht mehr die ganze Platte ausgewechselt zu werden, sondern nur noch ein Materialstück von der Größe des Brandbereiches. Hierdurch wird bei häufig öffnenden Schaltern eine erhebliche Ersparnis an Material erzielt.It is then no longer necessary to replace the entire plate, only a piece of material the size of the fire area. This is used for frequently opening Switches achieved a considerable saving in material.
Die Erfindung ist in der Zeichnung in einem Ausführungsbeispiel dargestellt, c und k sind die Kontakte, zwischen denen beim Öffnen der Funken entsteht. Diese sind zum Schutz mit einem Funkenkamin umgeben, der aus den Seitenwänden s und in diesen eingelegten Kaminplatten t besteht. Der Kamin schützt die Polschuhe u des Blasmagneten m mit der Spule e gegen Zerstörung. In zwei einander gegenüberliegende Kaminplatten sind nach der Erfindung runde Stücke p aus feuerfestem Material eingesetzt, deren Umfang dem Funkenbereich des Hüpfers entspricht. Unter Umständen kann es genügen, diese Anordnung nur bei einer Platte zu treffen. Die Öffnung in den 'Kaminplatten ist gefalzt und so angeordnet, daß die Stücke p in der Richtung nach der Seitenwand zu herausnehmbar sind. Sie werden also, wenn die Kaminplatte in den Kamin eingesetzt ist, selbsttätig vor dem Herausfallen geschützt.The invention is shown in the drawing in an exemplary embodiment, c and k are the contacts between which the spark occurs when the spark is opened. For protection, these are surrounded by a spark chimney, which consists of the side walls s and firebacks t inserted into them. The chimney protects the pole shoes u of the blowing magnet m with the coil e against destruction. According to the invention, round pieces p made of refractory material are inserted into two opposing firebacks, the circumference of which corresponds to the spark area of the hopper. Under certain circumstances it may be sufficient to make this arrangement for only one plate. The opening in the firebacks is folded and arranged so that the pieces p can be removed in the direction towards the side wall. So you are automatically protected from falling out when the fireback is inserted into the fireplace.
