Zusatz zum Patent 437153.Addendum to patent 437153.

Patentiert im Deutschen Reiche vom 8. Dezember 1925 ab. Das Hauptpatent hat angefangen am 17. Dezember 1924.Patented in the German Empire on December 8, 1925. The main patent started on December 17, 1924.

Gegenstand des Patents ist ein selbsttätiger Mitnehmer für Radsatzdrehbänke, bei welchem gezäumte Exzenterklauen oder Klemmbacken unter gleichzeitigiem achsialem Vortrieb selbsttätig zum Angriff kommen, und zwar durch die Wirkung des Gewichtes einer Verbindungsstange, welche die Antriebshebel der beiden Klemmbacken miteinander verbindet. Infolge dieser Einrichtung kommen naturgemäß immer beide Klemmbacken gleichzeitig zum Angriff. Es hat sich nun aber gezeigt, daß ein soidher gleichzeitiger Angriff der Kliemmbackien durchaus nicht notwendig ist, da der Radsatz zwischen den Spitzen der Drehbank liiegt, so· daß ein richtiges Erfassen und Festhalten des Radsatzes durch dieThe subject of the patent is an automatic driver for wheel set lathes, at which bridled eccentric claws or The clamping jaws automatically attack with simultaneous axial propulsion, and by the effect of the weight of one Connecting rod that connects the drive levers of the two clamping jaws with one another. As a result of this facility, of course, both clamping jaws always come at the same time to attack. But it has now been shown that a simultaneous attack the Kliemmbackien absolutely not necessary is, since the wheel set lies between the centers of the lathe, so that a correct detection and holding the wheelset by the
