Abstract: An apparatus for retracting a pool cover from over a pool, or extending a pool cover over a pool, includes a pool cover collecting drum supported for rotation on its ends, and a drive gear connected to the drum. A power gear for engaging the drive gear is operably connected to a portable, battery operated electric drill by a power shaft. When the drill is activated, the drive gear rotates the pool cover collecting drum to collect and retract the pool cover from over the pool. The pool cover is placed back over the pool by operation of a complementary apparatus on the opposite side of the pool, such as a rope spool collecting apparatus having an engageable drive gear. The gear-driven spool pulls on a rope attached to a rigid end or carrier of the pool cover. As the pool cover is extended and retracted it slides in a track, allowing the cover to serve as a safety cover. The gears may be located in a sealed housing filled with lubricant.
