tätig in Tätigkeit tretenden Schaltwerkes ein, zwei oder mehrere Mitnehmer abwechselnd aus dem rechten in den linken Gewinde. gang ein-und ausgeschaltet werden und hiedurch die Hin-und Herbewegung von mit dem Schaltwerk verbundenen Gestängen od. dgl. hervorgerufen wird.
Die Zeichnung veranschaulicht ein Ausführungsbeispiel einer derartigen Umschaltvorrichtung
EMI1.4
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

<Desc/Clms Page number 2>
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

Vorgang in umgekehrter Weise wiederholt.
Derartige Umschaltvorrichtungen sind mit Vorteil bei Transportvorrichtungen, Schleifapparaten, Kratzenabziehapparaten, Schmutzmulden usw. verwendbar.

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.
EMI1.2
any position on the right-hand and left-hand screw spindle can be set up. This switching device is characterized in that on a right and left
EMI1.3
active switching mechanism one, two or more drivers alternately from the right to the left thread. gear can be switched on and off and thereby the back and forth movement of rods or the like connected to the switching mechanism.
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

<Desc / Clms Page number 2>
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.
