In den Wänden 247, 248 der übereinander liegenden Dichtköpfe 43, 233 sind Doppelarmhebel 249 und 250 gelagert, welche durch eine nicht näher bezeichnete Öffnung in den Wandungen 43, 233 hindurch greifen. Der innere Arm 251 und 252 überdeckt die jeweilige, hier nicht gezeigte Auslösestange der Sicherung und die außerhalb der Wandungen 43, 233 befindlichen Arme 253 und 254 sind etwa L-förmig abgewinkelt und wirken mit Zapfen 255 und 256 zusammen, die an einer ersten Übertragungsstange 257 radial vorspringend befestigt sind.In the walls 247, 248 of the superimposed sealing heads 43, 233 double lever 249 and 250 are mounted, which engage through an unspecified opening in the walls 43, 233 through. The inner arm 251 and 252 covers the respective, not shown here trigger bar of the fuse and the outside of the walls 43, 233 located arms 253 and 254 are approximately L-shaped angled and cooperate with pins 255 and 256, which on a first transmission rod 257th are attached radially projecting.
Am Dichtkopf 234, der ebenfalls topfförmig ausgebildet ist, ist ebenfalls ein Doppelarmhebel 258 gelagert, dessen einer Hebelarm 259 die Auslösestange der Sicherung 231 übergreift, wogegen der andere Arm 260 in gleicher Weise wie die Arme 253 und 254 abgewinkelt ist, wobei der Arm 260 mit einem radial vorspringenden Zapfen 261 an einer zweiten Übertragungsstange 262 zusammenwirkt.At the sealing head 234, which is also pot-shaped, a double arm 258 is also mounted, one lever arm 259, the release rod of the fuse 231 overlaps, whereas the other arm 260 is angled in the same way as the arms 253 and 254, wherein the arm 260 with a radially projecting pin 261 on a second transmission rod 262 cooperates.
Die Doppelarmhebel 249, 250 und 258 verlaufen horizontal und sind in den Wandungen der Dichtköpfe jeweils um eine vertikal verlaufende Achse schwenkbar. Die Übertra- gungsstange 257 befindet sich auf der einen Seite des Dreiecks außerhalb desselben, parallel zur Basis des Dreiecks, wogegen die andere Übertragungsstange 262 auf der gegenüberliegenden Seite, also der spitzen Seite des Dreiecks angeordnet ist. Die beiden Übertragungsstangen 257 und 262 verlaufen senkrecht und in einer Ebene, die parallel zu der Ebene der Platte 100 verläuft.The double-arm 249, 250 and 258 extend horizontally and are each pivotable in the walls of the sealing heads about a vertically extending axis. The transmis- The rod 257 is located on one side of the triangle outside of it, parallel to the base of the triangle, whereas the other transmission rod 262 is arranged on the opposite side, so the sharp side of the triangle. The two transmission rods 257 and 262 are perpendicular and in a plane which is parallel to the plane of the plate 100.
An den oberen Enden der Übertragungsstangen 257 und 262 sind Hebelarme 263 und 264 befestigt, deren freie Enden mit einer Kupplungsstange 265 gekuppelt sind, wobei die Kupplungsstange 265 unter einem Winkel zu der Ebene verläuft, in der sich die Ü- bertragungsstangen 257 und 262 befinden. Dabei weist das freie Ende des HebelarmsAt the upper ends of the transmission rods 257 and 262, lever arms 263 and 264 are fixed, the free ends of which are coupled to a coupling rod 265, the coupling rod 265 being at an angle to the plane in which the transmission rods 257 and 262 are located. In this case, the free end of the lever arm
263 von der Platte 100 weg; das freie Ende des Hebelarmes 264 weist zur Platte 100 hin, so dass das Ende der Kupplungsstange, welches mit dem Arm 264 verbunden ist, einen geringeren Abstand aufweist, als das andere Ende der Kupplungsstange 265, welches mit dem Arm 263 verbunden ist.263 away from the plate 100; the free end of the lever arm 264 points towards the plate 100, so that the end of the coupling rod, which is connected to the arm 264, has a smaller distance than the other end of the coupling rod 265, which is connected to the arm 263.

Sollte nun die Sicherung 231 ansprechen, dann betätigt der Doppelarmhebel 258 über den Zapfen 261 die Übertragungsstange 262 im Uhrzeigersinn, wodurch der HebelarmIf now the fuse 231 respond, then actuates the double arm 258 via the pin 261, the transmission rod 262 in a clockwise direction, whereby the lever arm
264 verschwenkt und auf die Kupplungsstange 265 eine Kraft ausgeübt wird, die diese verschiebt, wobei die Kupplungsstange 265 wegen des Langloches 266 frei beweglich ist. Umgekehrt wenn durch Ansprechen der Sicherung 30 sich die in der Zeichnung links befindliche Übertragungsstange entgegen dem Uhrzeigersinn verschwenkt, verschiebt der Hebelarm 263 die Kupplungsstange 265 und diese kann sich aufgrund des Langloches 267 frei, d. h. unabhängig von der Stellung der Übertragungsstange 262 bewegen.264 pivoted and on the coupling rod 265 a force is exerted, which shifts them, wherein the coupling rod 265 is freely movable because of the elongated hole 266. Conversely, if by addressing the fuse 30, the left in the drawing transmission rod pivoted counterclockwise, the lever arm 263 moves the coupling rod 265 and this can be due to the slot 267 free, d. H. regardless of the position of the transmission rod 262 move.
Mit der Kupplungsstange 265 ist ein Bowdenzug 268 verbunden, über den die Bewegung der Kupplungsstange auf ein Auslöseelement 269 in der Verklinkungsstelle eines Schaltschlosses einwirkt. An der Kupplungsstange 265 ist eine Anzeigestange 270 befestigt, an deren freiem Ende eine Anzeigefahne 271 befestigt ist, die die Schaltstellung bzw. die Auslösestellung der Sicherungen anzeigt, d. h. anzeigt, ob eine Sicherung angesprochen hat.With the coupling rod 265, a Bowden cable 268 is connected, via which the movement of the coupling rod acts on a trigger element 269 in the Verklinkungsstelle a switching mechanism. On the coupling rod 265, a display rod 270 is attached to the free end of a display flag 271 is attached, which indicates the switching position or the release position of the fuses, ie indicates whether a fuse has addressed.
