Abstract
ABSTRACT
A reel for winding insulated single - conductor electrical cable, particularly welding cable. The reel has a rectangular frame which supports a floating shaft - drum assembly and two cable guid-ing rollers. Assembly further comprises a pair of slipping conduct-ors which also serve as wire terminals. Slipping conductors are pushed together by means of a shaft mounted spring which pulls a drum towards a frame, and thus squeezes conductors located between the drum and the frame.

~0 SPECIFICATION
~ his -invention relates to devices used for wlnding insu lated electrical cables, for the purpose of temporary storage, and more particularly to a reel for winding welding cable~.
Most of the truck mounted welding machino~ and also some of the ln-shop used machines have long welding cables. Between ~ob~
or at the ~nd of the working day, cables are usually hand-coiled on a hook near the welding machine.
The desirability of mechanising this work has been reco~-nized in the pa~t, and several products attempting to solve this problem have been introduced. None of these devices were thoroughly accapted by welders for numerous reasons, such as small storage ca-pacity and complexity of de~ign.
The ob~ect of this invention is to provide a simple, re-liable and :inexpensive device, which will eliminate the time con-suml~g hand-coiling of cables.

Disc spring 12 on the end of the shaft 5 provide pre~suro needsd to keep the conductors 7 and 8 in good contact by pulling the drum 4 towards the bushing 2, and ~quee~ing th~ conductor~ together~

Claims (6)
PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
1. A cable reel for winding insulated electrical cables, having an enclosed rectangular frame, and a drum which is attached to a floating shaft, said shaft protruding on both sides of the frame, and having on one end attached a handle, said assembly comprising further a stationary electrical conductor, mounted on said frame and a rotating electrical conductor, mounted on said drum, both said conductors having flat ends positioned in the center of the drum, and having wider sides parallel with the side of the drum, both said conductors having planar surfaces in continuous electrically con-ductive engagement by means of axially clamping said conductors, between said frame and said floating shaft and drum assembly.
2. A cable reel as defined in claim 1 in which conductors are pushed together by means of a compression spring, disc spring, resilient plastic, or any other spring-like element, causing axial pressure on the shaft of the drum and thus squeezing said conductors between the drum and frame.
3. A cable reel as defined in claim 2 and further compris-ing nuts on a threaded portion of the shaft for adjusting tension in the spring.
4. A cable reel as defined in claim 2 and further compris-ing fasteners such as bolts, retaining rings, dowel-pins or similar, used to retain the spring element in the desired place, and transfer the axial force from the spring element on to the shaft of the drum.
5. A cable reel as defined in claim 1 in which an additional piece of flat electrical conductor, a slip-washer, is positioned between two conductors, thus eliminating direct contact between said conductors.
6. A cable reel as defined in claim 1 having parts of the conductors, which are in electrical conductive engagement, spherical ly shaped.
