 Rastenscheibe und Rolle für die Sperrung in den Schalistellungen versehen ist. Die bisher gebräuchliche Rastensperrung, bei der die Rolle auf einem einarmigen abgefederten Hebel gelagert ist, hat den Nachteil, dass sie der Drehung der Walze in der einen Richtung einen grossen Widerstand entgegensetzt. 



   Neuerungsgemäss wird der die Rastenrolle tragende, unter Federwirkung stehende Hebel, mit zwei Armen versehen, die an ihren Enden mit Lagerungen versehen sind, mit denen der Hebel gegen zwei symmetrisch zur Schaltachse angeordnete Zapfen sich anlegt, von denen je nach der Drehrichtung der Schaltwalze einer als Drehpunkt für den Rastenhebel dient. 



   In der Zeichnung ist ein mit dem Kennzeichen der Neuerung versehener Walzenschalter dargestellt. a ist die Schaltwalze, b die Rastenseheibe und c die in die Verzahnung derselben eingreifende Rolle. Die Rolle c sitzt an dem Hebel d, dessen Arme g,   h   die Zapfen e, f umgreifen. Die Zapfen e, fliegen symmetrisch zu einer durch die Achsen der Walze und der Rastenrolle gelegten Geraden, i ist die Anpressfeder für die Rastenrolle. Je nach der Drehrichtung der Schaltwalze dient entweder der Zapfen e, oder der Zapfen f als Drehpunkt für den die Rolle c tragenden Hebel d, wobei der jeweils andere Arm des Hebels d von dem Zapfen abgleitet. 



   Durch die neuerungsgemässe Ausbildung der Rastensperrung wird ein nahezu reibungsloses Schalten erreicht, wobei das Überschalten der Schaltstellungen nach   Möglichkeit   vermieden ist.

 EMI1.1
 
 EMI1.2
 Detent disc and roller for locking in the switch positions is provided. The hitherto common notch lock, in which the roller is mounted on a one-armed spring-loaded lever, has the disadvantage that it opposes the rotation of the roller in one direction with great resistance.



   According to the innovation, the spring-loaded lever carrying the detent roller is provided with two arms which are provided at their ends with bearings with which the lever rests against two pins arranged symmetrically to the switching axis, one of which depending on the direction of rotation of the switching drum The pivot point for the detent lever is used.



   In the drawing, a roller switch marked with the innovation is shown. a is the shift drum, b is the ratchet disc and c is the role that engages in the toothing of the same. The roller c sits on the lever d, the arms g, h of which encompass the pins e, f. The pins e fly symmetrically to a straight line laid through the axes of the roller and the notch roller, i is the pressure spring for the notch roller. Depending on the direction of rotation of the shift drum, either the pin e or the pin f serves as the fulcrum for the lever d carrying the roller c, the respective other arm of the lever d sliding off the pin.



   The design of the notch lock according to the innovation achieves almost smooth switching, with over-switching of the switching positions being avoided as far as possible.
