Abstract

In some embodiments, a cable spool includes a hub having an outer surface that is retractable and expandable, and a single end plate affixed to an end of the hub. In other embodiments, an apparatus includes an assembly of cascaded, temporarily interlocked spools that can be used for simultaneous despooling or spooling of multiple cable coils.

Claims

1. A cable spool comprising:

a hub having a discontinuous hub surface that is retractable and expandable, the hub including a shaft, a center body slidable over the shaft, arms that are connected to the center body and that extend radially outward from the center body, and surface pieces at ends of the arms, the surface pieces forming the discontinuous hub surface; and

a single circular, flat end plate affixed to an end of the hub, the end plate having spokes;

wherein an upper edge of each surface piece has a notch configured to receive a spoke of a second spool such that the upper edges of the surface pieces are slidable along the spokes of the second spool.

2. The spool of claim 1, wherein first ends of the surface pieces are hinged to the spokes of the end plate and second ends of the surface pieces are hinged to ends of the arms.

3. The spool of claim 1, wherein the hub surface retracts when the center body is moved toward the end plate.

4. The spool of claim 1, further comprising a stop for constraining movement of the center body away from the end plate.

5. A method of using the spool of claim 1 to spool or despool a coil of cable, the method comprising

laying the end plate on the ground;

placing the cable coil over the hub when the hub surface is retracted;

expanding the hub surface to prevent the cable from freewheeling; and

rotating the spool.

6. The method of claim 5, further comprising retracting the hub after rotating the spool;

and removing a partial coil from the retracted hub.

7. A method of using a plurality of spools of claim 1 to despool or spool a plurality of cable coils, the method comprising cascading a plurality of the spools, wherein cascading each spool includes:

laying an end plate of an n^th spool on the shaft of an n-1th spool;

placing a coil over a retracted hub of the n^th spool; and

expanding the hub of the n^th spool;

after all of the spools have been stacked and interlocked, loading the interlocked spools on a structure that allows the interlocked spools to rotate; and

simultaneously despooling or spooling the cables from the interlocked spools.

8. The method of claim 7, further comprising bundling and removing partial coils from the hubs.

9. The spool of claim 1, wherein the shaft is coupled to the end plate by a bearing, the bearing configured to receive a shaft of another spool.

10. Apparatus comprising first and second cascaded, temporarily interlocked spools for simultaneous cable spooling and despooling;

each spool including a single circular, flat end plate having spokes, and a hub having a discontinuous hub surface that is retractable and expandable, the hub including a shaft coupled to the end plate by a bearing, a center body slidable over the shaft, arms that are connected to the center body and that extend radially outward from the center body, and surface pieces at ends of the arms, the surface pieces forming the discontinuous hub surface;

wherein the shaft of the first spool is inserted into the bearing of the second spool;

wherein the spokes of the second spool are received in notches in upper edges of the surface pieces of the first spool; and

wherein the end plate of the second spool forms a terminating plate for the first spool.

11. The apparatus of claim 10, further comprising means for supporting the interlocked spools to rotate for the spooling or despooling.

12. The apparatus of claim 11, wherein the supporting means includes a base that carries spaced apart rollers for accommodating the interlocked spools while the interlocked spools are resting on the perimeter of its end plates.
