ABSTRACT:
An electric power cord take-up reel having an external housing, a shaft mounted in the housing, and a spool journalled on the shaft for storing a length of electric power cord and spring-biased to rewind a length of cord previously withdrawn from the reel, and supplied with electric current from an external source through stator contacts in the housing and rotor contact rings on the spool. The reel includes an electric switch and a camming ratchet ring for interrupting the flow of current to the stator contacts while the cord is being withdrawn or retracted or is in its stored position on the spool. The camming ratchet ring is engageable with a latch pawl for locking the reel in a stationary position when a desired length of cord is withdrawn at which time the ring also activates the switch to energize the cord for use.
