Abstract: A bathtub self-cleaning system includes a series of pop-out spray nozzles designed to be arranged about the confining walls of a bathtub and the like. The spray nozzles are connected by a manifold to a combined concentrate and dilutent mixing control valve. The control valve serves to initially mix the dilutent such as water with the concentrate such as a detergent to provide a diluted cleaning solution. Subsequently, the control valve discharges the cleaning solution via the manifold through the spray nozzles. The spray nozzles when popped-out are directed at the surfaces of the confining walls for their cleaning by the cleaning solution. Upon consumption of the concentrate within the mixing control valve, only dilutent is discharged therefrom to rinse the confining walls of residual cleaning solution or dirt. In this manner, a bathtub may be automatically cleaned without the necessity of any manual scrubbing thereof.

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.

Abstract: A cleaning head for connection at bottom surfaces of a swimming pool to an automatic pressure control system includes a chamber and a rotary expansion collar disposed in the chamber. The collar has relatively thin cylindrical walls and an inclined slot extending through the cylindrical wall, allowing the collar to expand in response to increased water pressure produced by the pressure control system. The slot is closed when the collar is relaxed and is opened in response to water being forced under high pressure into an interior portion of the chamber surrounded by the collar. Water ejected from the interior portion through the open slot causes the collar to rotate. As the water pressure increases, the collar expands further until its outside surfaces frictionally engage the chamber wall, stopping rotation of collar.
