Abstract
Abstract A wind-up reel for cooling and storage of heavy duty utility electric cord which includes three elements in the form of a housing open at one side, a rotating facer plate to close that opening and an idle plate to form a spool with the face plate and rotatable with the coil and face plate to protect the coil against abrasion and to provide a lateral bearing surface against the outer case. A storage recess in the face plate will house one functional end of the cord. Spaced reinforcing on the housing and the facer plate provides a structure which can be light in weight while maintaining the proper shape for the function.

Claim 1
Independent Claim
256 words
A portable storage case for an electrical power cord having male and female connectors at each end which comprises: (a) a generally dish-shaped circular molded plastic case having a radially extending side face having a first dished portion to form a first flat central wall portion spaced inwardly from the side face and an axially extending outer wall to overlie said dished portion and form a storage chamber for said power cord, the case being open at the side opposite said side face, (b) a circular face plate disposed at said opening to close said case and relatively rotatable to said case, said face plate having a second central dished portion having a second flat central wall lying parallel to said first flat central wall portion, (c) a third circular plate having a third central dished portion telescoped over said first central dished portion and affixed to said flat central wall of said second central dished portion, said third plate having a brim in the form of a cone extending from said third dished portion toward said side face of said case, the edge of said brim at the base of said cone lying in contact with said face to stabilize said circular face plate and said third circular plate, said face plate and said third circular plate forming a spool for receiving a power cord wound around the axis of said plates, and (d) axle means mounting said flat central walls of said spool on said first flat central wall of said first dished portion.

Claim 3
Dependent Claim
51 words
A portable storage case as defined in claim 1 in which the open edge of said axially extending outer wall has an offset portion radially outward of said outer wall, and said circular face plate has an axially extending flange positioned within said offset portion to rotate within said offset portion.
Claim 4
Dependent Claim
108 words
A portable storage case as defined in claim 1 in which the second dished portion is ported to allow a length at the end of a cable to pass in coiled condition from said spool to the interior of said second dished portion for supplemental storage of said end length, and a U-shaped bar having opposed legs pivotally mounted on the walls of said second dished portion to allow the bight of said U-shaped bar to move from a position adjacent the wall of said second dished portion to a position diametrically across said second dished portion to retain said coiled end length within said second dished portion.
