Description

  

      Neuerunz    an Walzenschaltern.    Die vorliegende Erfindung bezieht sich  auf eine die Anordnung der Kontaktfinger  betreffende Neuerung an Walzenschaltern.  



  Auf der Zeichnung ist ein Ausführungs  beispiel des Erfindungsgegenstandes     imSchnitte     durch den die Kontaktfinger tragenden Sockel  dargestellt.  



  Die     Kontaktfinger    b sind auf der der  Schalterwalze     a    zugekehrten Seite je mit  einem Anschlagstreifen c versehen,     gegen    des  sen Oberteil sie in der Ruhelage, das heisst,  wenn sie nicht Kontakt machen, durch eine       Vorspannung    angedrückt werden. Am untern  Ende ist jeder Kontaktfinger b am aufwärts  gerichteten Schenkel d eines winkelförmigen  Trägers e befestigt, der durch eine Schraube     f     am Sockel i festgehalten wird.

   Am untern  Erde jedes Schenkels d befindet sich auf der  Aussenseite ein Nocken g, auf der Innenseite  eine mechanisch geschwächte Stelle     h,    zum  Zwecke, nach der Montage des Walzenschal  ters jeden Kontaktfinger am Nocken     g        mit-          telst    einer Zange erfassen und durch Ab  biegen des Trägers e in seiner schwächsten  Stelle h genau einstellen zu können, ohne    dadurch die     Vorspannung    des Kontaktfingers  zu ändern. Jenes Abbiegen kann statt     mit-          telst    Zange auch auf anderem Wege ge  schehen, zum Beispiel mittelst Schraube,  Keil usw.



      Brand new at roller switches. The present invention relates to an innovation in roller switches relating to the arrangement of the contact fingers.



  In the drawing, an embodiment of the subject matter of the invention is shown in section through the base carrying the contact fingers.



  The contact fingers b are each provided with a stop strip c on the side facing the switch drum a, against the sen upper part they are pressed in the rest position, that is, when they do not make contact, by a bias. At the lower end of each contact finger b is attached to the upwardly directed leg d of an angular support e, which is held by a screw f on the base i.

   On the lower ground of each leg d there is a cam g on the outside, on the inside a mechanically weakened point h, for the purpose of grasping each contact finger on the cam g with a pair of pliers after mounting the roller switch and by bending the carrier e can be set precisely in its weakest point h without changing the preload of the contact finger. Instead of using pliers, this turning can also be done in other ways, for example using a screw, wedge, etc.

PATENTANSPRUCH: Neuerung an Walzenschaltern mit Kontakt fingern mit Anschlag und Vorspannung, da durch gekennzeichnet, dass der Träger jedes Kontaktfingers ausserhalb der Befestigungs stelle des letztern mit einem Nocken und zwischen diesem Nocken und der Befestigungs stelle mit einem mechanisch geschwächten Teil versehen ist, der es ermöglicht, den Kontaktfinger nach erfolgter Montage durch Abbiegen des Trägers ohne Änderung der Vorspannung des Kontaktfingers genau ein zustellen. PATENT CLAIM: Innovation in roller switches with contact fingers with stop and preload, as characterized in that the support of each contact finger outside the fastening point of the latter is provided with a cam and between this cam and the fastening point is provided with a mechanically weakened part that makes it possible to adjust the contact finger exactly after installation by bending the carrier without changing the preload of the contact finger.
