Appletons' cyclopaedia of applied mechanics: a dictionary of mechanical engineering and the mechanical arts . ion apparatus into a regular brake, the power ofthe governor may be increased ; and in this way it may be applied for the regulation of water-wheels,and such steam-engines as are furnished with variable expansion gear, which are better regulated byincreasing or diminishing the amount of expansion than by throttling the steam. Fig. 2224 represents Silvers marine governor. A A are loaded arms pivoted in their centres atB to the shaft C, which receives motion in any suitable manner from the engine. The arms A Aare connected together through the medium of the sliding sleeves D D, the sleeve D being united toarms A A by means of the rods E E, and sleeve B by means of the rods EE. FE are bracketson the arms A A, to which the ends of the rods EE are attached. These brackets are placed at anangle of 45°, so that the line of draught of the arms and rods, when the balls fly out, is always paral-lel to the shaft C. The centrifugal force of the balls is counteracted by the employment of a spiral. spring /, to which the sleeve D is attached by means of clamps G. The tension of the spring isincreased or diminished at pleasure by turning the nut J, which moves the claw-collar K out or in,thus rendering the governor accordingly more or less sensitive, as desired. The collar K terminatesin a screw on which the moves. When motion is communicated to the spindle by the engine,the balls will have a tendency to fly out in the direction of the arrows, and to move the sleeves D Dlaterally. The sleeve D is furnished with a collar H, which is grasped by a forked crank M, pivotedto the standard 0. The lower branch of the lever JY is connected with a rod leading to the throttle-valve. The connection and operation of the sleeve D on the throttle-valve are similar to those ofordinary governors, and require no particular description. There are various other forms of marine governor
