Abstract
Abstract A reel for transporting a coiled electric cord a substantial distance from an electrical source of power to activate an electric appliance. The reel comprises a spool-like body having interior cone-shaped journals rotatably supported on matching cone-shaped bearings mounted on an axle. An elongate handle is rotatably mounted at one end of the spool for holding the reel and a shorter handle affixed to the other end of the spool to rotate the same about the longitudinal axis of the axle. The transfer of electricity to an appliance is provided by means of an electrical receptacle secured to the spool. The reel incorporates adjustable means for regulating the rotation of the spool to compensate for varying tensile loads on the cord.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
266 words
An electric extension cord reel which comprises: a spool-like body defined by a first and second annular plate spaced apart by an elongate cylinder having a bore extending through central openings in an inner and outer face of the plates, the end wall portions of the cylinder being flared conically outwardly adjacent to the inner faces to merge integrally with the peripheral wall in the openings and form a pair of opposed cone-shaped journals providing a longitudinal axis of rotation therethrough and said second plate having further a handle-like projection disposed on the outer face adjacent to the peripheral edge thereof and adapted to rotate the spool about its longitudinal axis of rotation, an axle disposed partly within the bore of said cylinder arranged to rotatably and cooperatively support said spool in the journal of said second plate, an adjustable bearing member mounted on the axle adapted to rotatably and cooperatively support said spool in the journal of said first plate, an elongate handle co-axially mounted on said axle outwardly of the adjustable bearing member and adapted to be coupled in registry therewith, an electrical outlet receptacle secured to said outer face of said second plate having a set of recesses therein to receive the prongs of an electric plug connected to an appliance, an elongate electric extension cord wound on said cylinder having an inner end plugged into another set of recesses disposed in the outlet receptacle and the outer end adapted to be plugged into a wall socket, and adjustable means for regulating the rotation of said spool about said longitudinal axis of rotation.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
71 words
The reel as recited in claim 1, wherein said axle comprises: an elongate shaft having a threaded end portion extending outward of said opening in said first plate and the other distal end being flared outwardly into a cone-shaped bearing surface adapted for slidable and rotatable engagement with said second plate journal, the distal end providing further a finger holding projection extending outward of said outer face of said second plate.
Claim 4
Dependent Claim
90 words
The reel as recited in claim 2, wherein the adjustable bearing member comprises: a nut-like body having a threaded bore, a square end portion for engagement with the jaws of a wrench and the other end portion expanded abruptly from a plane surface normal to the bore and extending outwardly into an inverted cone-shaped bearing surface, the body being adapted to be threadedly mounted on the threaded end portion of the shaft so as to bring the cone-shaped bearing surface in slidable and rotatable engagement with said first plate journal.
Claim 5
Dependent Claim
61 words
The reel as recited in claim 3, wherein the elongate electric cord comprises: a bracket secured to said inner face of said second plate arranged to hold an end portion of said cord adjacent to said outlet receptacle to prevent inadvertent uncoupling of said inner end plug from said receptacle when unwinding the full length of said cord from said cylinder.
Claim 6
Dependent Claim
60 words
The reel as recited in claim 4, wherein the adjustable means for regulating the rotation of said spool comprises: axial reciprocal movement of the nut-like body relative to said axle adapted to slidably and rotatably engage or disengage said bearing surfaces with said journals when adjusting the rotational moment on said spool applied by varying tension loads on said cord.
Claim 7
Dependent Claim
57 words
The reel as recited in claim 5, wherein the elongate handle comprises: a cylindrical tube having an opening at one end and a threaded bore therein, the tube arranged to be rotatably mounted on said axle and the end brought in abutting contact with the square end of said nut-like body to form a jam nut therewith.
Claim 8
Dependent Claim
39 words
The reel as recited in claim 6, wherein the handle-like projection disposed on the outer face of said second plate comprises: a collar rotatably mounted on said projection, and fastening means adapted to secure the collar on said projection.
