   In Fig. 6 ist ein ähnlicher Aussehalter wie in Fig.   1-3   gezeigt, aber die   Schraube   wird anstatt von einer Feder von dem biegsamen Faden 11, an welchem das Gewicht 54 hängt, beeinflusst. Der Faden ist über Rollen 55   und J6 geführt.   Das Gewicht 54 geht durch'einen stufenförmigen Anschlag 58 hindurch, auf dessen Stufen die Übergewichte 59, 60, 61 ruhen. Ein   weiteres   Übergewicht 68 ist in einer ausser Tätigkeit gesetzten Lage gezeichnet, indem es an Stützen 63 sitzt, die   herausschiebbar   sind. Mittels solcher Stützen kann man zu jeder Zeit ein beliebiges der Übergewichte ausser Tätigkeit setzen.

   Das Gewicht   54   nimmt beim Steigen allmählich die einzelnen Übergewichte mit, so dass sieh dasselbe mit zunehmender Höhe vergrössert, und umgekehrt. 



   In Fig. 7 ist ein Ausschalter wie in Fig. 4 gezeigt, aber anstatt der Feder ist ein Faden 43 da. an welchem ein Gewicht 64 mit Übergewicht 65 und Anschlag 58 angeordnet ist. In Fig. 8 ist ein Ausschalter wie in Fig. 7 gezeichnet, aber der Faden 43 wirkt auf die Bewegung der Führungsstange 5 mit schrägführender Kraft dadurch, dass derselbe durch die im Arm 68 gelagerte Rolle 66 abgelenkt ist.

Hiebei wird die quer zur Bewegungsrichtung der Aufhängung wirkende, durch die Ausschaltfeder 11 erzeugte Kraft durch die gleichfalls quer wirkende, durch die Entlastungsfeder   43,   Fig. 9 bzw. das Entlastungsgewicht 64, Fig. 8, erzeugte Kraft ausbalanziert und hiedurch die Reibung der Stange 5 in der Führung 6 vermindert. 



   In Fig. 10 ist ein Ausschalter wie in Fig. 5 gezeichnet, aber die Feder ist durch einen Faden 11 und Gewicht    & f   ersetzt. Der Faden 11 greift am Bolzen 50 an und führt über die Rolle 69 der Stange 46 und dann über   Rolle 5   hinunter zu dem am Ende aufgehängten Gewicht 54. Die Stange 46 geht durch die   Hülse 19, welche   mittels des Bolzens 50 im Hebel 16 drehbar gelagert ist, hindurch. In Fig. 11 ist

   In Fig. 5, a circuit breaker of the type shown in Fig. 1, 2 and 3 is drawn, but in which the spring 11 is loaded instead of tension on compression and around the bolt 10 swings a guide rod 46, which is supported by the spring 11 is enclosed, which at one end on the support plate 47

   In Fig. 6 a similar look-out switch is shown as in Figs. 1-3, but the screw is influenced by the flexible thread 11 on which the weight 54 hangs instead of a spring. The thread is passed over rollers 55 and J6. The weight 54 passes through a stepped stop 58, on the steps of which the overweights 59, 60, 61 rest. Another overweight 68 is shown in an inactivated position in that it sits on supports 63 which can be pushed out. By means of such supports one can put any of the overweights out of action at any time.

   The weight 54 gradually takes the individual excess weights with it as it climbs, so that it increases with increasing height, and vice versa.



   In Fig. 7 there is a circuit breaker as shown in Fig. 4, but instead of the spring there is a thread 43. on which a weight 64 with overweight 65 and stop 58 is arranged. In FIG. 8, a circuit breaker is drawn as in FIG. 7, but the thread 43 acts on the movement of the guide rod 5 with an oblique force in that it is deflected by the roller 66 mounted in the arm 68.

 direction of the guide rod 5 inclined. In this case, the force generated transversely to the direction of movement of the suspension and generated by the switch-off spring 11 is balanced by the likewise transverse force generated by the relief spring 43, Fig. 9 or the relief weight 64, Fig. 8, and thus by the friction of the rod 5 in the guide 6 decreased.



   In Fig. 10 a circuit breaker is drawn as in Fig. 5, but the spring is replaced by a thread 11 and weight & f. The thread 11 engages the bolt 50 and leads via the roller 69 of the rod 46 and then via roller 5 down to the weight 54 suspended at the end. The rod 46 passes through the sleeve 19, which is rotatably supported in the lever 16 by means of the bolt 50 is through. In Fig. 11 is

Claims

<Desc / Clms Page number 3> 3. Automatic switch according to claims 1 and 2, characterized in that the difference between the pressure at which the switch turns off and the pressure at which it turns on, by changing the angular position of the extreme limit position of the switch-off lever (16) by means of a adjustable stop bolt (32) can be regulated.

4. Automatic switch according to claims 1 and 2, characterized in that the spring or the weight suspended on the flexible thread acts on a driver lever (16 ', Fig. 4) which protrudes at a certain angle from the switch-off lever and either by one common bolt with the switch-off lever or around a bolt that is close to the pivot pin of the switch-off lever or around a bolt arranged on the switch-off lever itself, so that when leaving the limit position the driver lever first goes empty and only then when the spring or the suspended weight is already acting with greater torque and the driver lever has a certain speed, hits the switch-off lever and takes the same with it.

5. Automatic off switch according to claim 4, characterized in that the size of the pressure differences is regulated by changing the angle which the driver lever (16t) closes with the look-out plane (16), u. betw. by adjusting a stop screw (32, Fig. 4).

6. Automatic switch according to claims 1 to 5, characterized in that both the pressure level at which the switch turns off, and the size of the pressure differences when Switching on and off by removing or moving the suspension (10) from the membrane or the Piston when moving a sleeve (8) to which the suspension (10) is connected (Fig. 1-10), or by screwing in or out a tip (74) that supports a lever arm (57) that supports the suspension ( 10) carries (Fig. 11), can be regulated.

7. Automatic off switch according to claims 1 to 6, characterized in that a further spring or a further weight acts against the force acting on the membrane or the piston in such a way that it relieves the spring for the release mechanism (Fig. 4,5, 7,8,9).

8. Automatic circuit breaker according to claims 1 to 7, characterized in that the weight acting on the membrane or the piston and simultaneously on the disconnection mechanism or as an aid only on the membrane or the piston during its movement by means of gradually automatically increasing overweights changes and is set up in such a way that the overweights can be put out of action individually or all and thereby both the pressure level when switching off and the size of the pressure differences when switching on and off can be changed.

9. Automatic circuit breaker according to claim 7, characterized in that the direction of force (43, Fig. 8 and 9), in which that spring or that weight acts which relieve the disconnection mechanism, is inclined to the direction of movement of the suspension (10) such that the force acting transversely to the direction of movement of the suspension and generated by the switch-off spring (11) or the like is balanced by the force also acting transversely and generated by the relief spring or the like, and as a result, the friction of the rod (5) in the guide (6) is decreased.
