Abstract
A power regulating apparatus for controlling power to a cyclic load in which a pivotally-mounted constant speed motor has a fixed diameter pulley on the motor output shaft operatively connected to a variable speed pulley mounted on a driven shaft whereby motor reactive torque due to an increase in load on the motor causes the motor and its fixed diameter pulley to approach the variable speed pulley allowing the effective diameter of the variable speed pulley to increase for reducing the rate of rotation of the variable speed pulley and increasing the torque of the driven shaft.
