Abstract

4606. Baeder, J. March 6. No Patent granted (Sealingfeenot paid). Variable-speed gearing.-Relates to change-speed belt gearing, especially suitable for machine tools. Figs. 1 and 2 show the application of the invention to a lathe. A step pulley v is mounted so as to slide on the countershaft w, and a corresponding pulley c is fixed to the lathe spindle. One side r of the belt passes under a guide-roller l, and the other side r<1> of the belt passes round a tension pulley l'. The pulley l<1> is carried by a bracket s, which is arranged to slide in guides t and carries a number of weights g for the purpose of applying the tension. Upon the belt being changed from one step to another of the pulley c, the pulley v is correspondingly moved along the countershaft, and by movement of the belt along the steps of the pulley v a wide variation in speed ratios may be obtained. When a great number of speed variations are not required, the pulley v may be replaced by a wide cylindrical pulley or drum fixed to the countershaft.
