 Die Arbeitsweise ist folgende :
Befindet sich z.   B.   der obere Mitnehmer e im Gewinde der Schraubenspindel, so ist der untere
Mitnehmer e vom Gewinde abgehoben, wie dies Fig. 1 zeigt. Wird nun die Schraubenspindel a

 infolgedessen wird der Mitnehmer e aus dem Gewinde der Schraubenspindel ausgehoben. Gleichzeitig werden die unteren halbrunden Flächen   I   aus den Ausschnitten der Hebel   d1   herausbewegt, so dass diese freigegeben sind und der Mitnehmer e1 unter der Wirkung der Federn f in das linke Gewinde der Schraubenspindel hineingedrückt wird. Der Gleitkörper b wird daher nach links

  Switching device to achieve a reciprocating movement.
 EMI1.1
 the changeover can only take place after having covered the entire path given by the threaded part of the screw spindle.

   The drawing illustrates an embodiment of such a switching device
 EMI1.4
 The working method is as follows:
Is z. B. the upper driver e in the thread of the screw spindle, so is the lower
Driver e lifted off the thread, as shown in FIG. If the screw spindle a

 As a result, the driver e is lifted from the thread of the screw spindle. At the same time, the lower semicircular surfaces I are moved out of the cutouts of the levers d1, so that they are released and the driver e1 is pressed into the left thread of the screw spindle under the action of the springs f. The sliding body b is therefore to the left

 Repeat the process in reverse.



   Such switching devices can be used with advantage in transport devices, grinding devices, scraping devices, dirt troughs, etc.
