Centrifugal actuator assembly

A centrifugal actuator assembly adapted to be mounted on a rotatable shaft having a base with a hole formed therethrough for mounting on the rotatable shaft,

• a pair of actuating levers, each of said pair of levers having a pair of legs affixed to said base on opposite sides of the longitudinal axis of the shaft and being responsive to the rotation speed of said base creating movement of said levers between a first and second position upon acceleration and deceleration of the assembly and means for biasing said levers to said first position, the improvement comprising:
• a sleeve slidably mounted on the shaft and having seat means formed thereon for seating said levers so that said levers can move said sleeve between a said first position and said second position, said sleeve having a shoulder with a collar extending radially therefrom, said sleeve having ramps formed between said collar and said seat means to facilitate the seating of the legs in the seat means during assembly of the actuator.

In an electric motor having a starting winding, a starting switch for energizing and deenergizing the starting winding, and a rotor shaft with a centrifugal actuator having a base rotatably mounted on said rotor shaft,

• a pair of actuating levers, each said lever having mirror-image bifurcated leg portions movably connecting a sleeve to the base,
• the sleeve being in a slidable relationship with the rotor shaft having a normally extending annular collar at one end thereof and a shoulder extending normally from said collar to provide seat means for the bifurcated leg portions of the actuating levers during normal pivotal actuator movement thereof, the improvement in the sleeve comprising:
• ramp means formed on said shoulder between said collar and said seat means to provide guides for the insertion of said mirror-image leg portions of said actuating levers within said seat means during the assembly of said centrifugal actuator.
