Patent-Anspruch:Patent claim: Vorrichtung zur beliebigen Veränderung des Uebersetzungsverhältnisses zweier durch einen Riemen verbundener Expansionsriemscbeiben, bestehend in einer zwischen beiden Scheiben sich erstreckenden, gegen beide verschiebbaren Stange (Q), die an ihren Enden für je eine Scheibe einen Keil (M) trägt, von denen der eine bei Verschiebung nach der einen Seite einen Kegel oder dergleichen (L) in axialer Richtung zwischen die radial verschiebbaren Segmente (F) der Riemscheibe einerseits drängt und diese erweitert, während andererseits durch gleichzeitiges Zurückziehen des anderen Keiles der bezügliche Kegel (L) die Segmente (F) der anderen Scheibe zusammenzieht und den Scheibenumfang verkleinert.Device for arbitrarily changing the transmission ratio of two expansion belts connected by a belt, consisting of a rod (Q) which extends between the two disks and can be moved against both, which carries a wedge (M) at its ends for one pulley, one of which contributes Displacement to one side pushes a cone or the like (L) in the axial direction between the radially displaceable segments (F) of the pulley on the one hand and expands it, while on the other hand, by simultaneously withdrawing the other wedge, the related cone (L) breaks the segments (F) the other disc contracts and the disc circumference is reduced.
