Abstract: A fitting and faceplate cap assembly, for use in swimming pools, and the like, with vinyl liners, comprises a fitting member which extends through an opening in the wall of the pool with a flange overlying the opening on the inner surface of the pool. The fitting is hollow to adapt it for connection to water return lines or drain lines commonly used in such swimming pools. The flange on the fitting has a circular groove formed in it with a pair of enlarged recesses extending from the groove on opposite sides of the opening through the fitting. The faceplate cap includes a circular ridge with a pair of spaced projections for matingly engaging the groove and recesses in the faceplate of the fitting. A gasket is attached to the inner surface of the faceplate cap.

Abstract: In swimming pools the pop-up cleaning nozzles threaded into walls in the pool bottom are removable by a rotatable tool that has a body with axially extending lugs which project into corresponding openings in the nozzle head. A vacuum cup centrally of and recessed into the body attaches to the nozzle head for removing or replacing it.

Abstract: A rotational indexing nozzle arrangement has been devised wherein positive and consistent indexing action takes place under the influence of the application of fluid pressure and its relief by the action of an indexing or biased spring which becomes relaxed during the first stage (outward) movement of the indexing of the rotational nozzle head and which bites in and holds thereby causing the nozzle head to rotate during the second stage (inward) movement of the discharge head. The extent of the incremental indexing is determined by the length and angle of the biasing spring, or member. For improved operation a bearing of the ball or roller type may be disposed at the inward end of the nozzle arrangement whereby the resistance of the closing spring to rotation of the nozzle head is lessened.
