Abstract
Abstract Knock-down shipping and storage reel for the electric cable, wire rope and fiber rope industries. The reel is constructed to be disassembled when it reaches its destination and the cable or rope has been payed off the reel, and is returned to its shipping point in a knocked-down condition. The reel comprises a pair of parallel spaced flanges or heads, which are fluted for strength when made from metal and have openings extending therethrough concentric with the centers of the reel heads. A spacer tube spaces the flanges apart, concentric with the centers of the reel heads and is detachably secured to each of these reel heads. The carrying media for the cable may comprise circumferentially spaced cables or strands of metal or natural or synthetic fibers, which may be round or generally flat in cross secton. The cables or strands each have metallic terminals at each end, one of which may be a boltlike head. The other end may be threaded to receive a nut, such as a wing nut. Each end of the cable or strand may also be threaded for certain applications. The cables fit through circumferentially spaced holes in the reel heads and serve not only to hold the reel heads in parallel spaced relation with respect to each other, but also serve as a carrying media for the cable to be stored on the reel. Inserts of plastic or wood may be internally recessed to partially conform to the cables, and placed on the cables between the reel heads and retained to the cables and reel heads as tension is taken up on the tensioning cables forming the material carrying media.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
150 words
A knock-down reel for flexible cable and the like, comprising: a pair of spaced flanges forming reel heads, each of said reel heads having an opening concentric with the center thereof, a spacer tube concentric with said openings and connected between said flanges to space said flanges apart and form a bearing for the reel, spaced flexible members maintained under tension, and equally spaced radially outwardly of the center of said tube, individual means for each flexible member and accessible from the outside of at least one of said reel heads for maintaining said flexible members under tension and said flanges in parallel spaced relation with respect to each other, and segmental inserts mounted on said flexible members between said reel heads and carried by said flexible members and maintained to said flexible members by the compressive force of said flanges as tension is taken up on said flexible members.
Claim 2
Dependent Claim
150 words
A knock-down reel for flexible cable and the like, comprising: a pair of spaced flanges forming reel heads, each of said reel heads having an opening concentric with the center thereof, a spacer tube concentric with said openings and connected between said flanges to space said flanges apart and form a bearing for the reel, spaced flexible members maintained under tension, and equally spaced radially outwardly of the center of said tube, individual means for each flexible member and accessible from the outside of at least one of said reel heads for maintaining said flexible members under tension and said flanges in parallel spaced relation with respect to each other, and segmental inserts mounted on said flexible members between said reel heads and carried by said flexible members and maintained to said flexible members by the compressive force of said flanges as tension is taken up on said flexible members.
Claim 3
Dependent Claim
59 words
The knock-down reel of claim 1, wherein the segmental inserts are recessed to fit on said flexible members and are carried by said flexible members between said reel heads to form a continuous cylindrical drum, and are maintained on said flexible members by the compressive force of said reel heads as tension is taken up on said flexible members.
Claim 4
Dependent Claim
44 words
The knock-down reel of claim 1, in which the flexible members are relatively flat in cross section and each include a plurality of flexible cables stitched together, and having parallel terminals extending from opposite ends thereof adapted to be secured to said reel heads.
Claim 5
Dependent Claim
37 words
The knock-down reel of claim 1, in which an annular flat member is recessed in at least one of said reel heads and forms a bearing means for the means taking up tension on the flexible members.
Claim 6
Dependent Claim
200 words
A knock-down reel for flexible cable and the like, comprising: a pair of spaced flanges forming reel heads, each of said reel heads having an opening concentric with the center thereof, a boss on at least one of said reel heads defining a spacer tube receiving opening, a spacer tube, means on said spacer tube to interengage one end portion of said spacer tube and other means retaining the spacer tube to the other reel head to extend through the spacer tube receiving opening therein, said boss being internally threaded and said spacer tube being externally threaded and the end of said spacer tube opposite the threaded end thereof being flanged, and means to secure a flanged portion of the spacer tube to the associated reel head, spaced flexible members maintained under tension and defining the barrel of said reel and spaced radially outwardly of the center of said tube in circumferentially spaced relation with respect to each other, and forming a load carrying media, and individual means for each flexible member and accessible from at least one of said reel heads for maintaining said flexible members under tension and said flanges in parallel relation with respect to each other.
Claim 7
Dependent Claim
200 words
A knock-down reel for flexible cable and the like, comprising: a pair of spaced flanges forming reel heads, each of said reel heads having an opening concentric with the center thereof, a boss on at least one of said reel heads defining a spacer tube receiving opening, a spacer tube, means on said spacer tube to interengage one end portion of said spacer tube and other means retaining the spacer tube to the other reel head to extend through the spacer tube receiving opening therein, said boss being internally threaded and said spacer tube being externally threaded and the end of said spacer tube opposite the threaded end thereof being flanged, and means to secure a flanged portion of the spacer tube to the associated reel head, spaced flexible members maintained under tension and defining the barrel of said reel and spaced radially outwardly of the center of said tube in circumferentially spaced relation with respect to each other, and forming a load carrying media, and individual means for each flexible member and accessible from at least one of said reel heads for maintaining said flexible members under tension and said flanges in parallel relation with respect to each other.
