Abstract: This invention involves a fluid flow device which is in the form of a spout-end for a plumbing fixture such as a bathtub, and which is devised to establish a substantially silent, smooth clear and laminar flow of water into the plumbing fixture. The spout-end includes two adjacent flat screens of different meshes, followed in the path of flow by a fluid straightener, such as a ''''rosette,'''' for establishing a plurality of paths which are substantially parallel to each other, and then followed by another pair of screens both of which are concavely shaped at substantially different radii of curvature so that a gap or chamber is centrally formed between the two concaval screens for diverting the parallel streams into a tapered or converging stream which is substantially continuous and laminar.

Abstract: A hydrotherapeutic apparatus for use with a conventional bathtub. The apparatus produces an active whirlpool stream within the bathtub. The apparatus includes a pump, located in a remote point, having a conduit means coupled to the normal drain of the bathtub, for receiving water from the bathtub via the drain, raising the water pressure and for reapplying the withdrawn water under pressure through the same drain. A unitary nozzle apparatus may be inserted into the drain of the bathtub whenever whirlpool action is desired and this unitary structure includes means for feeding air for venturi action into the nozzle structure for ''''bubbling'''' the water emitted through the nozzle.
