Description:
"This invention relates to a new and useful improvement in electric motors, particularly alternating-current motors, wherein there are employed starting-coils through which the current is directed when the motor is started, said coils when the motor attains speed being automatically cut out. When the armature attains speed, said armature automatically throws into operative position a clutch mechanism whereby the armature becomes coupled to the shaft."
