   Man kann die in den Zeichnungen dargestellte   Einrichtung mannigfach abändern, das   wesentliche Merkmal bleibt immer das, dass der   Wiederholungsumschalter,   welcher die Schliessung des Magneten 691 des betätigenden Zylinders selbsttätig herstellt und unterbricht, unmittelbar durch die Bewegung des Kolbens im Zylinder 69 Antrieb erhält, statt durch einen pneumatischen Kolben betätigt zu werden. 



   Im   Uanpt-Patent   ist auch eine Sicherbeitsvorrichtung beschrieben, welche die schritt weise Bewegung des Kontrollers zum Stillstande bringt, sobald der der Speiseleitung entnommene Strom eine vorbestimmte Grenze überschreitet. Diese Sicherheitsvorrichtung besteht aus einem Ventil oder Schieber im Rohr   81,   welches den   betätigenden     Zylinder 6. 9   mit dem den Wiederholungsumschaslter   19,   20 betätigenden Zylinder 5 verbindet. 



   Da nach vorliegender Erfindung der Wiederholungsumschalter nicht sauf pneumatischem Wege betätigt wird, so wird deshalb die Sicherheitsvorrichtung abgeändert, und der Elektromagnet 94, dessen Strom sich nach Massgabe der Stromstärke in den Motoren ändert, wird derart angeordnet, dass er einen   Umschalter unmittelbar betätigt : dieser ist   in der Zeichnung durch die Stromschlussstücke 941, 942 dargestellt und liegt im   Nebenschiuss zum Wiedr-     holungsumschalter.   



   Man ersieht, dass, sobald die Stromstärke in dem Elektromagneten 94 die Grenze überschreitet, für welche er eingestellt ist, sein Anker angezogen wird. und das   beweglich

   The device shown in the drawings can be modified in many ways, the essential feature always remains that the repeat switch, which automatically establishes and interrupts the closure of the magnet 691 of the actuating cylinder, is driven directly by the movement of the piston in the cylinder 69 instead of by a pneumatic piston to be actuated.



   The Uanpt patent also describes a safety device which brings the step-wise movement of the controller to a standstill as soon as the current drawn from the feed line exceeds a predetermined limit. This safety device consists of a valve or slide in the pipe 81, which connects the actuating cylinder 6, 9 with the cylinder 5 actuating the repeater switch 19, 20.



   Since, according to the present invention, the repeat switch is not actuated pneumatically, the safety device is therefore modified and the electromagnet 94, the current of which changes according to the current intensity in the motors, is arranged in such a way that it actuates a switch directly: this is shown in the drawing by the current connection pieces 941, 942 and is in the shunt to the repetitive switch.



   It can be seen that as soon as the current intensity in the electromagnet 94 exceeds the limit for which it is set, its armature is attracted. and that movable

   cylinder (69) of the controller controlling electromagnet (691) is connected in series, characterized in that the movable part (ss) of this switch is mechanically connected to the actuating piston (692) of the working cylinder, so that the current in the magnet (691 ) of the working cylinder is interrupted when the piston is in this
