Description

Bei dem Hauptpatent 81q.233 wird die Quecksilberröhre mit der eingebauten Stauscheibe durch einen Elektromagnet gekippt, der über eine Kontaktvorrichtung, die mit dem Einstellhebel in Verbindung steht, gesteuert wird.In the main patent 81q.233, the mercury tube is built in with the Baffle plate tilted by an electromagnet, which via a contact device, which is in communication with the adjustment lever is controlled.

Gemäß der vorliegenden Erfindung kann auf den Elektromagnet und die Steuerkontaktvorrichtung verzichtet werden. Die Quecksilberröhre mit der eingebauten Stauscheibe wird mechanisch durch den Einstellhebel der Schaltkupplung gekippt.According to the present invention, the electromagnet and the Control contact device can be dispensed with. The mercury tube with the built-in The baffle plate is tilted mechanically by the adjustment lever of the clutch.

Ein Ausführungsbeispiel ist in der Zeichnung' schematisch dargestellt.An exemplary embodiment is shown schematically in the drawing.

Die Zeichnung zeigt eine schematische Darstellung der Triebwerkswelle und der Bremseinrichtung,@ teilweise in Ansicht ist der Elektromotor dargestellt mit angebauter Kippvorrichtung für die Schaltröhre.The drawing shows a schematic representation of the engine shaft and the braking device, @ partially in view of the electric motor is shown with attached tilting device for the interrupter.

1 ist der Einstellhebel, der über eine Zugstange 2 mit dem Nähmaschinenfußtritt 3 in Verbindung steht. Am Motorlagerschild 4 ist ein Lagerböckchen 5 befestigt, auf dem der Hebel 6 an der Lagerstelle 7 drehbar angeordnet ist. Der Hebel 6 ist durch einen Bolzen 8 in Verbindung mit dem Einstellhebel 1 gebracht. An einem beispielsweise an der Tischplatte angeschraubten Lagerböckchen 9 ist eine Quecksilberröhre 10 um -einen Drehpunkt 11 schwenkbar angeordnet. Die Quecksilberröhre 1o trägt an einem Bolzen 12 einen Zapfen 13, der in einem Langloch 14 des Hebels 6 gleiten kann. In der gezeichneten Lage stellt das in der Röhre befindliche Quecksilber 15 über die Stauscheibe 16 und den Kontakt 17 die elektrische Verbindung mit dem Netz 18 und dem Elektromagnet 19 her. Die Bremseinrichtung kann in der im Hauptpatent 814233 beschriebenen Weise zur Wirkung gelangen. Sobald der Fußtritt 3 betätigt wird, wird die Quecksilberröhre 1o gekippt und entsprechend der im Hauptpatent beschriebenen Weise die Stromführung zum Magnet unterbrochen.1 is the setting lever that steps with the sewing machine foot via a pull rod 2 3 communicates. A bearing block 5 is attached to the motor end shield 4, on which the lever 6 is rotatably arranged at the bearing point 7. The lever 6 is brought into connection with the setting lever 1 by a bolt 8. One example Bearing block 9 screwed to the table top is a 10 µm mercury tube -A pivot point 11 is arranged to be pivotable. The mercury tube 1o carries on one Bolt 12 has a pin 13 which can slide in an elongated hole 14 of the lever 6. In the position shown is the mercury in the tube 15 on the Baffle plate 16 and the contact 17 provide the electrical connection to the network 18 and the electromagnet 19. The braking device can be found in the main patent 814233 described way to take effect. As soon as the footstep 3 is pressed, is the mercury tube tilted 1o and according to that described in the main patent Way, the current flow to the magnet is interrupted.
