Abstract

132,800. Fortuna Werke Spezial Maschinen-fabrik Ges. Aug. 20, 1918, [Convention date]. Expunding pulley; have separately-slidable flanges f, f<1>, Fig. 1, pressed towards one another by cam surfaces i upon members k secured to a central shaft such as a. The surfaces are shaped as shown in Fig. 6 with a view to producing bulance between the driving torque, the wedging; action of the belt, and the reaction at the cam surface, so that a small external force can change the speed ratio. The cams may be engaged by rollers on the nangee, or by co-acting cants. The flanges f, f<1> are slidable on a sleeve lloose on the shaft a The flanges g<1>,of a similar pulley. driven by the belt e from the first pulley, slide on a sleeve l<1>loose on its shaft b. The pulleys are operated in unison by cross pins n engaging straight slots p in the shafts and curved slots )m. in the sleeves, so as to cause the sleeves and flanges to turn relatively to the cams i. One pulley only may be so operated, the other working automatically by the altered tension of the belt.
