Kreisringen ergänzen bzw. durch ein kreisringförmiges Stück gebildet werden können. Beim Einspannen wird das Schneckenrad f durch die sich ständig drehende Welle 9 mittels der Reibungskupplung solange gedreht, bis der Anpressungsdruck dem Reibungswiderstand in der Kupplung entspricht, der durch die Stellschrauben t beliebig geändert werden kann. Falls sich beim Betriebe die Walze in den Setzstöcken zwischen dem unteren Lager und dem oberen Bügel etwas lockern sollte, so tritt demzufolge ein selbsttätiges Nachspannen der Klemmwirkung ein.
Das Vorrücken des Frässchlittens und die Arbeit des Fräsers erfolgt in üblicher Weise und wird nach beendeter Fräsung mit der Rückwärtsbewegung des Frässchlittens auch der Drehsinn der Welle h umgeschaltet, so dass nunmehr infolge der Kupplung der Sperrklinken v mit den Zähnen u der Platte o ein unbedingte Freigeben des Werkstückes durch die Schrauben d erfolgt, worauf sich der gleiche Vorgang wiederholt.
Es ist ohneweiters klar, dass das Einspannen auch durch ein Hochdrücken der Walzen unterlage bewirkt werden und dass die gleiche Vorrichtung für Klein- @nd Handbetrieb sinngemässe

PATENT. ANSPRÜCHE :
1. Vorrichtung zum Festhalten von Walzenzapfen beim Fräsen, dadurch gekennzeichnet, dass das Festklemmen und Lösen durch einen vom Fräskopfantrieb abgeleiteten Nebenantrieb erfolgt, wobei die Klemmwirkung in den Setzstöcken beim Anziehen verstellbar begrenzt ist, während die Freigabe mit direkter Kupplung erfolgt.

EMI2.1
Supplement circular rings or can be formed by a circular piece. When clamping, the worm wheel f is rotated by the constantly rotating shaft 9 by means of the friction clutch until the contact pressure corresponds to the frictional resistance in the clutch, which can be changed as desired by the adjusting screws t. If, during operation, the roller should loosen a little in the setstocks between the lower bearing and the upper bracket, the clamping effect will be automatically re-tensioned.
The advance of the milling carriage and the work of the milling cutter take place in the usual way and, after milling is completed, the direction of rotation of the shaft h is switched with the backward movement of the milling carriage, so that now, as a result of the coupling of the pawls v with the teeth u of the plate o, an unconditional release of the workpiece is carried out by the screws d, whereupon the same process is repeated.
It is already clear that the clamping can also be brought about by pressing up the roller support and that the same device for small @ and manual operation analogously
EMI2.2
PATENT. EXPECTATIONS :
1. A device for holding roll necks during milling, characterized in that the clamping and loosening is carried out by a power take-off derived from the milling head drive, the clamping effect in the steady restraints being adjustable when tightening, while the release takes place with a direct coupling.
