  Einrichtung an Kontrollern mit einer durch Kurbeldruckknopf oder verschiebbare Kurbel betätigten Schaltvorrichtung. 



   Es sind Einrichtungen an Kntrollern bekannt, die den zu steuernden Motor selbsttätig abschalten, wenn der Führer einen   Kurbeldruckknopf   oder eine achsial verschiebbare Kurbel loslässt, wie dies z. B. in der österreichischen Patentschrift Nr. 40274 beschrieben ist. Andererseits sind Einrichtungen bekannt, die eine Unterbrechung des Motorstromkreises dann hervorrufen, wenn die Kurbel von einer Stellung, die einer höheren Geschwindigkeit entspricht, zurückgedreht wird auf eine solche, die einer niedrigeren Ge-   schwindigkeit   entspricht. Die Anordnung dieser beiden Schalteinrichtungen nebeneinander ergab bisher verwickelte Konstruktionen. Die Anordnung nach der Erfindung stellt als Weiterbildung der Konstruktion nach dem Patente Nr. 40274 eine einfache und betriebssichere Vereinigung der genannten Einrichtungen dar. 



   Die Erfindung besteht darin, dass eine Kurvenscheibe, die beim Niederdrücken des Kurbeldruckknopfes von der Kurbel aus achsial gegen eine Federkraft niedergedrückt und dadurch in Eingriff mit dem die Schnappfinger schaltenden Hebel gebracht wird, durch eine weitere, auf der Antriebswelle befestigte Scheibe unter Vermittlung von schrägen
Zähnen und von einer Sperrklinke beim   Zurückdrehen   der Kurbel gegen die Haltekraft 
 EMI1.1 
 Schaltvorrichtung wird geöffnet. Bei Drehung der Kurbel im Einschaltsinne bleiben die schrägen Zähne der Scheibe ohne Einfluss auf Schnappfiuger, Steuerung und Kurvenscheibe. 



   Die Zeichnung zeigt ein Beispiel in Ansicht bzw. teilweisem Schnitt (Fig. 1) und Draufsicht (Fig.   2).   Es bezeichnet a die Kurbel, b den Kurbeldruckknopf, c eine Scheibe, die durch den Kurbeldruckknopf niedergedrückt werden kann und die Schaltvorrichtung zur Unterbrechung des Motorstromkreises steuert, d einen Schnappfinger der die Schaltvorrichtung schaltenden Hebel, e eine mit schrägen Zähnen versehene Scheibe, f eine mit

  Device on controllers with a switching device operated by a push button or a sliding crank.



   There are devices known to Kntrollern that automatically turn off the controlled motor when the driver releases a crank push button or an axially movable crank, as z. B. is described in Austrian Patent No. 40274. On the other hand, devices are known which cause an interruption of the motor circuit when the crank is turned back from a position which corresponds to a higher speed to a position which corresponds to a lower speed. The arrangement of these two switching devices next to each other resulted in complicated constructions. The arrangement according to the invention, as a further development of the construction according to patent no.40274, represents a simple and reliable combination of the mentioned devices.



   The invention consists in that a cam disk, which is axially depressed against a spring force by the crank when the crank push button is depressed and thereby brought into engagement with the lever that switches the snap fingers, is replaced by a further disk attached to the drive shaft by means of inclines
Teeth and a pawl when turning back the crank against the holding force
 EMI1.1
 Switching device is opened. When the crank is turned in the switch-on direction, the inclined teeth of the disc have no effect on the snap-in device, control and cam disc.



   The drawing shows an example in view or partial section (Fig. 1) and plan view (Fig. 2). It denotes a the crank, b the crank push button, c a disc that can be depressed by the crank push button and controls the switching device to interrupt the motor circuit, d a snap finger of the lever switching the switching device, e a disc with inclined teeth, f one with
 EMI1.2
