A center of the spool includes a clutch bearing in the center of both the first cylindrical lip and the second cylindrical lip that provides a rotational axis for the cable spool to rotate around. The apparatus may also include a feed slot near the first cylindrical lip that provides a passage for cable to pass from the second cylindrical lip to the first cylindrical lip. ## Claims ### Claim 1 An apparatus, comprising: a cable spool; and a drive adaptor configured to turn while a cable is unwound from the cable spool and to lock while the cable spool is rewound. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the cable spool includes a first cylindrical lip on a first side of a cable spool housing and a second cylindrical lip on a second side of the cable spool housing, wherein the cable is wound around the first cylindrical lip and the second cylindrical lip, and wherein a clutch bearing is at a center of both the first cylindrical lip and the second cylindrical lip. ### Claim 3 (depends on 2) The apparatus of claim 2, wherein the first cylindrical lip has a longer diameter than a diameter of the second cylindrical lip. ### Claim 4 (depends on 2) The apparatus of claim 2, further comprising a feed slot contiguous with the first cylindrical lip that provides a passage for the cable to pass from the second cylindrical lip to the first cylindrical lip. ### Claim 5 (depends on 2) The apparatus of claim 2, further comprising a power spring band affixed at a first end to an interior surface inside an area of the first cylindrical lip and affixed at a second end to the clutch bearing, and wherein the power spring band is comprised of an elastic material that extends as the cable spool is rotated. ### Claim 6 (depends on 1) The apparatus of claim 1, further comprising a spool supporting protrusion extending from a body of a cable spool housing. ### Claim 7 (depends on 6) The apparatus of claim 6, further comprising an electronic data interface affixed to one end of the cable and resting against an orifice in the spool supporting protrusion. ### Claim 8 (depends on 7) The apparatus of claim 7, wherein the electronic data interface is at least one of a video graphics adaptor (VGA), a universal serial bus (USB) interface and a high definition multimedia interface (HDMI). ### Claim 9 (depends on 1) The apparatus of claim 1, wherein a cable spool housing comprises a front plate. ### Claim 10 (depends on 1) The apparatus of claim 1, wherein a cable spool housing comprises a back plate. ### Claim 11 (depends on 10) The apparatus of claim 10, further comprising a dampener affixed to the back plate of the spool housing in direct contact with a clutch bearing to reduce rotational speed of the spool. ### Claim 12 (depends on 1) The apparatus of claim 1, further comprising a brake including another clutch bearing and a spring biased release lever that regulates movement of a clutch bearing to reduce undesired movement of the cable. ### Claim 13 (depends on 12) The apparatus of claim 12, wherein the brake further comprises a toothed gear that is in direct contact with an outer gear of the spool and which is rotated around the another clutch bearing. ### Claim 14 (depends on 13) The apparatus of claim 13, wherein the brake further comprises a pivot arm, wherein the spring biased release lever is in direct contact with the pivot arm and causes the pivot arm to stop movement of the toothed gear when the spring biased release lever is in a closed position. ### Claim 15 (depends on 13) The apparatus of claim 13, wherein the brake further comprises a pivot arm, and wherein the spring biased release lever is in direct contact with the pivot arm and causes the pivot arm to permit movement of the toothed gear when the spring biased release lever is in an open position. ### Claim 16 An apparatus, comprising: a first cable spool including a first cylindrical lip; and a second cable spool affixed to an opposite side of the first cable spool including a second cylindrical lip; wherein a cable is configured to move from the second cylindrical lip to the first cylindrical lip. ### Claim 17 (depends on 16) The apparatus of claim 16, further comprising a clutch bearing in the center of both the first cylindrical lip and the second cylindrical lip that provides a rotational axis and a drive adaptor configured to turn freely while the cable is being unwound from the spool and to lock when a rewinding movement of the spool is initiated, and wherein the drive adaptor is positioned inside the clutch bearing. ### Claim 18 (depends on 17) The apparatus of claim 17, further comprising a power spring band affixed at a first end to an interior surface inside an area of the first cylindrical lip and affixed at a second end to the clutch bearing, and wherein the power spring band is comprised of an elastic material that extends as the first cable spool and the second cable spool are rotated. ### Claim 19 (depends on 18) The apparatus of claim 18, further comprising an electronic data interface affixed to one end of the cable and resting against an orifice in a supporting protrusion affixed to the first cable spool and the second cable spool. ### Claim 20 (depends on 19) The apparatus of claim 19, wherein the electronic data interface is at least one of a video graphics adaptor (VGA), a universal serial bus (USB) interface and a high definition multimedia interface (HDMI).
