Abstract: An automatically deployed water removal apparatus for use with a solid, flexible swimming pool cover to remove rainwater caught by the cover. In one embodiment, a head with a water inlet pivots from a stored position along the edge of a pool to a deployed position near the center of a deployed cover as the cover advances to its deployed, pool-covering position. In another embodiment, a water inlet is attached to and positioned in part by a tether cord that may be reeled out during cover deployment and reeled in during retraction of the cover.

Abstract: A multi-accessory hammer is provided having an rapid release accessory change mechanism that includes a housing mounted to the butt end of a hammer and having an opening therein. A resilient means such as a spring is mounted within the housing, and an accessory locking device is mounted over the spring. One end of this locking device extends through the opening in the housing and is capable of rapidly hooking onto an accessory. The locking device also has a side arm extending along the exterior of housing and is capable of urging the locking device against the resilient means to allow unhooking of the accessory from the locking device.
