  Kettenspanner für kleine Kraftwagen. 



   Bisher erfolgte bei kleinen Kraftwagen das Nachspannnen der Antriebsketten durch federnd und gleichzeitig verstellbar gelagerte Spannrollen. Hierbei ergibt sich der Nachteil, dass die mit der Kette mitschwingenden Spannteile zu schwer sind und den raschen Aufund Abwärtsbewegungen der Kette nicht folgen können. 



   Dieser Übelstand wird durch den den Gegenstand der Erfindung bildenden Kettenspanner beseitigt, bei welchem die Spannrolle an einer hakenförmig gebogenen Blattfeder sitzt, deren am Rahmen befestigtes Ende mittels Stellschraube einstellbar ist, so dass eine möglichst geringe schwingende Masse vorhanden ist. 



   Die Zeichnung veranschaulicht einen derartigen Kettenspanner. Die Blattfeder F ist am Rahmen   jE   bei a befestigt und trägt am anderen Ende eine die Kette K spannende Rolle S. Am Rahmen R sitzt ferner ein Stück g mit Muttergewinde, in welchem die Stellschraube St verschraubbar ist. Da die Feder F trotz ihrer Nachgiebigkeit vor und hinter dem Gewindestück g von der Stellschraube St und dem Rahmen R getragen wird, ist die schwingende und daher zu beschleunigende Masse eine möglichst kleine. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Chain tensioner for small cars.



   Up until now, the drive chains in small motor vehicles were re-tensioned by means of spring-loaded and adjustable tension rollers. This has the disadvantage that the tensioning parts that vibrate with the chain are too heavy and cannot follow the rapid up and down movements of the chain.



   This inconvenience is eliminated by the chain tensioner forming the subject of the invention, in which the tensioning roller sits on a hook-shaped leaf spring, the end of which is attached to the frame and can be adjusted by means of an adjusting screw, so that the vibrating mass is as low as possible.



   The drawing illustrates such a chain tensioner. The leaf spring F is attached to the frame jE at a and carries a roller S tensioning the chain K at the other end. On the frame R there is also a piece g with a nut thread, in which the adjusting screw St can be screwed. Since the spring F is carried by the adjusting screw St and the frame R in front of and behind the threaded piece g in spite of its resilience, the oscillating and therefore accelerating mass is as small as possible.
