Abstract
An extensible mast allows a payload to be supported at a distance from a supporting device. The payload may be connected via a cable to one or more components in the supporting device. A cable rotation apparatus allows a cable to rotate during dispensation of the cable, such as during extension or retraction of the extensible mast, while minimizing strain on the cable. The apparatus comprises a stationary spool, a furling core, and a rotating spool. A beveled gear on each of the spools engages a pair of beveled gears in the furling core. As the rotating spool rotates with respect to the stationary spool, the furling core rotates at one-half the speed and the cable is dispensed from an opening in the rotating spool. The furling core incorporates a guide wheel that maintains an orderly transfer of the cable from one spool to another.
