Sliding sleeve 2 is mounted at the upper end of spindle 1 and rotates with the spindle. Sleeve 2 has rigidly attached disk 3 which rests on two rollers 4. Rollers 4 are connected by turning pairs to shackle 5. Attached rigidly to sleeve 2 is cross-piece 6 from which two rods 7 are suspended with weights 8 at their lower ends. The weights carry braking shoes 9 which engage the inner conical surface of d rum 11. When spindle 1 rotates, weights 8 on rods 7 swing upwards. If the speed of the spindle exceeds the preset value, braking shoes 9 are pressed against drum 11, reducing the speed. The governor is adjusted to the required maximum speed by raising or lowering the mechanism with respect to drum 11 by means of screw 10.
