    Umstellvorrichtung für   den Plan-und Langzug an Drehbänken. 



   Es sind bereits Umstellvorrichtungen für den Lang-und Planzug an Drehbänken bekannt, bei denen zwei unter einander in Eingriff stehende Räder, von denen das eine von der Leitspindel aus betrieben wird, in einem drehbaren Arm gelagert sind, durch Schwingen dieses Armes in einem Kreise nach einander entweder mit den den Planzug oder den den Langzug bewirkenden Rädern in wechselnden Eingriff gebracht werden können.

Durch Drehung des Handgriffes y nach rechts (siehe gezeichnete Stellung) kommt das Getriebe b in Eingriff mit dem Transportrad e und dadurch ist der Antrieb für die

    Changeover device for flat and long pull on lathes.



   There are already switching devices for the long and face pull on lathes known in which two mutually engaging wheels, one of which is operated from the lead screw, are mounted in a rotatable arm by swinging this arm in a circle can be brought into alternating engagement with either the straight pull or the long pull causing wheels.
 EMI1.1
 Wheels are all stored in one plane and this has the disadvantage that the transmission ratio cannot be changed at will.

 in Fig.

   3 device shown in plan is also used to switch for long and straight pull on all types of lathes and has the advantage over known ones that one can

   The drive for the housing takes place from the pull spindle z by means of displaceable conicals

 which has its pivot point in lever a. This lever a swings around the bolt i and is moved to the right and left by means of a handle g and a disk with an eccentric pin M, which is guided in slot n. By turning the handle y to the right (see position shown), the transmission b comes into engagement with the transport wheel e and is therefore the drive for the
