Abstract: A full body massager apparatus is provided which is activated by water pressure from a plumbing fixture. The apparatus is held in the hand and rubbed over a persons body which is activated by water pressure from a water outlet whereby the water pressure will cause a vigorous vibration massaging effect as water passes through the apparatus over the persons body.

Abstract: A water ejecting gun simultaneously produces two kinds of ejecting flows, a straight flow and a spray flow. The gun disposes a rotating or spiral fan element in a water passage for producing the spray flow. The straight flow acts as a carrier for the spray flow. A mechanism for producing the spray and straight flows includes an inner sleeve, an outer sleeve rotatably and axially movable on the inner sleeve, a nozzle element disposed in the inner sleeve which defines a main flow passage and a sub-flow passage and a frusto-conical core element engaging the upstream end of the nozzle element to form a variable gap therebetween. When the gap is open, water flows to the main flow passage. When the gap is closed, a smaller water flow to the main flow passage occurs through radial and axial passages in the core element. The straight and spray water flows exit the gun simultaneously through an ejecting opening.

Abstract: A liquid sprinkler comprises a nozzle, a bridge including an outer section overlying the nozzle, and a rotor in alignment with the nozzle bore so as to be impinged by the water jet issuing therefrom. The outer bridge section includes a deflector surface aligned with the nozzle bore and having an enlarged area such that when the deflector surface is impinged by the axial jet from the nozzle bore, it produces an annular spray laterally of the sprinkler, whereby the sprinkler may be converted from a rotary sprinkler producing a rotating jet, to a static sprinkler producing an annular spray by merely removing the rotor from the nozzle and permitting the jet to impinge on the deflector surface area of the outer bridge section.

Abstract: A handheld water driven shower massager unit is provided which includes a housing having an internally disposed rotatable nozzle which is caused to rotate by the high velocity discharge of water from the nozzle. By eccentrically weighting the water discharge nozzle, an oscillating vibrational motion is applied to the entire device, thereby providing a massaging effect when pressed against the user. When held away from the user, the unit functions as a source of water spray for cleansing. The performance and characteristics of the unit can be modified through varying the flow rate of water through the unit, by changing the nozzle configuration, or by changing the angle of water discharge from the nozzle. Additionally, various cleansing and massaging pads can be removably attached to the unit in accordance with the needs of the user.

Abstract: To convert a conventional nonpulsating air/water mixer for a therapy tub, swimming pool, spa or the like to a pulsating mixer, an inexpensive pulsator fitting is used to replace the central eyeball portion of the mixer's outlet and mounting fitting. The pulsator fitting has at least one cross bar positioned to block the mixer's aerated water jet, and a small cylindrical rotor journaled on the cross bar. The rotor extends from the cross bar coaxially into the mixer body's outlet passage in the path of the aerated jet. The jet strikes a central portion of the upstream rotor end, travels through an angulated rotor passage, and exits the downstream rotor end at an angle relative to the rotor axis and at a point spaced apart from it, causing the rotor to spin. As the rotor spins, the exiting aerated jet rotates and is repetitively and intermittently blocked by the cross bar, thereby pulsing the jet.

Abstract: Lawn sprinkler incorporating a novel water distributing head having a "wobbling" motion. The base of the head is mounted loosely between shoulders near the end of a tubular water-supplying support arm. A water jet emerging from a nozzle at the end of the arm strikes internal vanes at the discharge end of the distributor head to cause the wobbling action. The support arm is journaled within a vertical bearing, and the action of the water jet causes the arm to be driven slowly through a circular path.

Abstract: A venturi-type mixer that produces an aerated water jet for spas, therapy pools, swimming pools and the like is provided with a pulsating action by means of a rotating flow disturbing blade mounted at the discharge end of the jet nozzle to repetitively intercept the increased velocity stream discharged by the nozzle. The flow disturbing blade has its velocity controlled and adjusted by means of a water-driven turbine rotor journalled upstream of the nozzle and geared to the flow disturbing blade. The amount of projection of the turbine rotor blades into the water stream is varied by changing the relative alignment of non-circular input passage to the jet nozzle with respect to a congruent non-circular input passage from the main water supply.

Abstract: An impeller is connected to a liquid-powered motor to be driven thereby. The impeller is of a type capable of moving a large volume of air of the order of as much as several thousand cubic meters per minute, which is ten or more times the volume of liquid used to power the motor. Some or all of the liquid applied to the motor to be transformed into mechanical energy is carried by a conduit to a point where it can suitably enter the air stream provided by the impeller. The conduit can carry the liquid to a point between the motor and the impeller so as to be picked up along with air and included in the stream forcibly projected from the impeller. Alternatively, the conduit can be routed around the impeller to discharge the liquid into the already formed air stream.

Abstract: A pulsating fluid nozzle is disclosed which comprises a body having an inner chamber and an outer chamber separated by a cylindrical wall. The inner chamber is supplied with fluid through a fluid outlet, and the outer chamber supplies fluid to the fluid outlets. The cylindrical wall has a port through which fluid can flow from the inner chamber to the outer chamber. A rotor is mounted for rotation in the outer chamber. The rotor has a blade extending from an annular hub which is adapted to fit around the cylindrical wall and block the flow of fluid through the port. The hub has an opening adapted to intermittently coincide with the port as the rotor turns to permit the flow of fluid through the port to produce a pulsating flow. The blade is adjacent to the opening and positioned to be contacted by a stream of fluid flowing through the port when the opening coincides with the port. The contact by the stream of fluid propels the blade to turn the rotor.

Abstract: A stream of water introduced to a shower head is split into two paths. The first water path is discharged in the form of a cone shaped spray. The second water path is channeled into a chamber containing a rotor rotationally responsive to the flow of water into the chamber and which rotor includes a chopper for regulating pulsed discharges of water through varying ones of a plurality of discharge ports. The proportional water flow in the two water paths is selectively variable. Air is introduced to the stream of water upstream of the water path split to aerate the water and reduce the quantity of water flow without an apparent water flow reduction to a user. A non-pulsating aerated shower head is also described.

The pinion carries a guide pin which is flushly engaged within the inclined slot for axial movement of the slide bushing when the pinion is rotated. At least one spray element is fixedly connected to the slide bushing for producing an adjustable output spray of liquid.

Abstract: A venturi type mixer that produces an aerated water jet for spas, therapy pools, swimming pools and the like, is provided with a pulsating action by means of a flow impeding spoiler that momentarily and repetitively disturbs the water jet that is projected into the mixing chamber. Disturbance of the jet effectively disables the vacuum produced by the venturi action to thereby cause discharge of a water stream of decreased velocity having considerably less entrained air. The spoiler is moved into and out of the water jet by means of an automatically reciprocating piston that is operated by a combination of a spring and the vacuum produced by the venturi action. Alternatively the spoiler may be rotated into and out of the path of the jet by a water driven rotor, or the jet orifice may be rotated relative to a fixed spoiler.

Abstract: A showering system includes a source of hot water and a showerhead fed from that source. To produce steam, there is a conduit that delivers water from the source to a showerhead and in which is defined an outlet. Disposed within the conduit is a selectively controlled diverter of the water arriving from the source, so as to direct it away from the showerhead and through the outlet in the form of a mist. The preferred showerhead is of a turbine-valve kind in which the turbine is driven by nozzles. Apertures in a flow director plate, governed by a control plate, feed nozzles predetermined to vary the force of water delivered from outlet orifices in correspondence with the number of the nozzles open to communicate with the inlet through the apertures.

Abstract: A diffuser for a hair dryer reduces the force of impact of air discharged from the hair dryer against the hair of a user. The diffuser includes a housing having an inlet port, an outlet port and a freely rotatable fan blade mounted within the housing. The inlet port is removably interconnected to the discharge nozzle of a hair dryer so that air discharged from the hair dryer enters the housing, strikes the fan, and causes it to rotate. The rotating fan disperses the discharged air into a plurality of diversely directed eddy currents which flow out of the outlet port. These less powerful eddy currents, which are applied to the hair of a user, will not upset the setting of hair.A screen can be interposed between the fan and the outlet port to prevent hair from becoming caught in the diffuser and to further disperse the eddy currents of air before they are discharged from the outlet port.

Abstract: A very fine fog or mist producing nozzle is disclosed wherein two or more balls rotate in an enclosed orifice chamber, into which the fluid is tangentially injected, to break up the fluid into a very fine mist. The nozzle produces a mist of much finer atomized particles than the prior art devices to thereby increase the efficiency of a fuel burner or similar device. The nozzle is such that it may be readily attached to an existing fluid flow line without major alterations.

Abstract: A spray head including a handle disk having an exposed front wall and manually engageable peripheral portion the wall having a set of jet nozzles arranged in a circle, the perforations having common communication with a set of fine spray nozzles; the handle disk being mounted for limited arcuate movement with respect to a housing having a mating perforated wall for exposing the jet nozzles or the perforations communicating with the spray nozzles. The interior of the housing forms a chamber in which water is caused to rotate and drive a rotor having at least one opening which passes intermittently across the jet nozzles or perforations depending on the position of the handle disk. When the jet spray nozzles are activated the effect of the rotor and its slot is to cause the jet nozzles to produce pulsating jets. When the fine spray nozzles are activated, the water entering the perforations is diffused to produce essentially constant flow through the fine spray nozzles.
