    Abstract: A centrifugal switch assembly for a motor having a starting circuit including a basket shaped actuator normally spring biased into engagement with switch contacts maintaining the starting circuit closed during static and motor low speed conditions. The switch actuator is mounted in a support member providing guide slots preventing rotation of the actuator relative to rotating motor components while being spring biased to the switch closed position. Centrifugal force responsive weights are pivotally mounted in the support member and engage the basket switch actuator moving it against the force of the biasing spring opening the switch contacts when the motor reaches a predetermined speed. The components of the actuator assembly are concentrically positioned upon the motor shaft adjacent the rotor and inwardly of the usual lubricating assembly in a manner without increasing the axial length of the motor.

    Abstract: A reversing control circuit for a single-phase alternating current induction motor operatively connected to a driven member which is operated thereby from an initial position to an extreme position at which it encounters a restraint of sufficient force to stall the motor and returned to the initial position. Upon the closing of a momentary contact switch, supply potential is applied therethrough across the main motor winding and also across the motor first direction phase winding through one movable contact and the corresponding alternate condition stationary contact of a double pole-double throw switch, maintained in the alternate condition of operation by the driven member in the initial position, and a series centrifugal switch. The energized motor rotates in the first direction to operate the driven member toward the extreme position and away from the double pole-double throw switch which returns to the normal condition of operation to connect the motor main winding across the supply potential through a movable contact and the corresponding normal condition stationary contact thereof and the centrifugal switch opens to disconnect the motor first direction phase winding. When the driven member has been operated to the extreme position at which it encounters a restraint of sufficient force to stall the motor, the centrifugal switch closes to apply supply potential across the motor second direction phase winding through a movable contact and the corresponding normal condition stationary contact of the double pole-double throw switch to reverse the direction of rotation of the motor to return the driven member to the initial position at which the double poledouble throw switch is operated thereby to the alternate condition in which all motor circuits are open.
