Abstract
Abstract An electric cord coiler comprising a hub member journaled on the spaced end walls of a hollow housing and carrying a partition preferably in the form of an annular plate to partition the interior of the housing into two axially separated spaces, these spaces being joined by a diametrical passage in the hub member so that a portion of an electric cord intermediate its ends can be placed in such passage and the contiguous portions of the cord at opposite ends of such intermediate portion can be wound around the hub on opposite sides of the partition with the extreme outer end portions of the cord extending outwardly through openings in the side wall of the housing. The effective length of the electric cord from extremity to extremity can be changed by either unwinding some of the cord from the hub member or winding more thereon. The coiler is characterized by its simplicity, its minimum number of different parts, its ease of manufacture and its ready assembly.
