Description:

"The apparatus consists of two weighted arms to the upper extremities of which are secured toothed quadrants working in a cylindrical rack placed in the main spindle of the governor in an opening sufficiently long to allow the rack to have a reciprocal motion equal to the demand of the valve which it may govern. When set in motion, the arms and their weights recede from the spindle by the centrifugal force given them, and thereby cause the toothed quadrants to operate on the cylindrical rack, which produces a reciprocal motion without the intervention of pins, levers, or connecting links."
