Abstract

591,355. Variable - speed gearing. HEYER, D. May 24, 1944, No. 10007. [Class 80 (ii)] An adjustable pulley 11 on the shaft of a motor 10 drives a fixed pulley 12 by means of a vee-belt 63. The pulley 11 comprises twin conical members 35, 36, which are adapted to be moved together to increase the effective diameter of the pulley by centrifugal weights 39 which move radially on a cross-pin 37 secured to shaft 33 and engage through rollers 40 with cam surfaces 44 and 45 on pulley member 36 and a member 46, connected by keys 48 to slide axially with the other pulley member 35, respectively. The pulley members 35 and 36 thus move towards or away from each other by equal amounts to maintain the alignment of the belt. The effective pulley diameter is decreased when the speed falls by the tension of the belt under the weight of the motor which is pivoted at 16 and the tension of a spring 51 which forces the two halves of the pulley apart. The pulley thus assumes its smallest diameter when the motor stops so that the drive is most favourable for re-starting. A handwheel 27 and screw 24 are provided for adjusting a stop 18 engaging the base 13 of the motor for controlling the maximum effective diameter of the,pulley 11 and the speed of the driven pulley 12 as shown by an indicating disc 61.
