Abstract

Improved storage apparatus for electric extension cords and the like that includes a reel for storing a power cord or pig tail, a second drum for storing the extension cord, and that further includes level wind apparatus which uniformly locates the extension cord on the second drum whereby long cords can be stored in a relatively small space without tangling.

Claims

1. Improved electric extension cord storage apparatus including:

a hollow housing;

first reel means including a shaft journaled in said housing and a drum mounted on said saft for receiving a power cord;

second reel means including a second shaft journaled in said housing and a second drum on said second shaft for receiving said extension cord;

means in said housing for electrically interconnecting said power cord and extension cord;

level wind means including a level wind shaft having left and right-hand helical grooves therein;

a follower mounted for reciprocating movement along said level wind shaft and having said extension cord passing therethrough;

a gear mounted on and rotatable with said second shaft;

a gear mounted on and rotatable with said level wind shaft is mesh with said gear on said second shaft causes rotation of said level wind shaft whereby rotation of said second shaft causes rotation of said level wind shaft and reciprocation of said follower to distribute said extension cord substantially uniformly along said second drum; and

resilient means for storing energy when said second shaft rotates to feed said extension cord from said second reel means and for causing rotation of said second reel means in a direction to rewind said extension cord.
