  • Patent number: 10471444
    Abstract: A showerhead engine includes a first plate joined to a second plate with a cavity therebetween. Water enters the cavity through an angled hole in the first plate and flows in a swirling motion about the central axis. A paddle wheel is spun within the cavity by the swirling water. A notched cutout in the paddle wheel forms an exit passage through a through hole in the second plate allowing the water to exit when the notched cutout lines up with slots in the second plate. The revolving paddle wheel continues to revolve thereby revolving the notched cutout and producing a revolving spray pattern.

  • Patent number: 8056831
    Abstract: A self-powered foam (e.g. compressed-air foam (CAF)) distributor has a rotor mechanism with impingement surfaces against which foam impinges to rotate the rotor. The rotor is mounted on an inlet shaft geared to an output shaft. A rotary outlet is mounted to the output shaft so that foam entering the distributor rotates the rotary outlet, which in turn projects foam around in a circular sweep. The rotary outlet can rotate over a full 360 degrees, providing superior coverage for a large floor space, such as in hangars or warehouses, with less water and concentrate than in unfoamed conventional systems. Having a compact vertical profile this versatile distributor can be installed in a floor trench of a hangar or on a wall or ceiling. Since all rotational energy is harnessed from the pressure of the foam itself, no external energy source is required to power the distributor.

  • Patent number: 8020788
    Abstract: A showerhead providing an improved pause mode that restricts the amount of water emanating from the head. The showerhead includes a first and second outlet nozzle, a valve body operative to be in fluid communication with a shower pipe, the valve body having first and second flow channels in fluid communication with the shower pipe, each of which is also in fluid communication with one of the outlet nozzles. The first and second flow channels have different cross-sectional areas. In another embodiment, the valve body further includes a valve center in fluid communication between the first flow channel and the shower pipe, and is also in fluid communication between the second flow channel and the shower pipe. The valve body further defines a first hole in fluid communication with the first flow channel and the valve center, and a second hole in fluid communication with the second flow channel and the valve center, with the second hole having a smaller cross-sectional area than that of the first hole.

  • Patent number: 7992809
    Abstract: Provided is a manual air-actuated spray paint apparatus and associated method for evenly disbursing paint in a controlled manner. Such an apparatus preferably includes a portable reservoir for holding the paint therein and a hand-actuated paint applicator removably coupled thereto. A mechanism for simultaneously discharging a single stream of paint and a volume of air may also be included. A discharge spout is removably mated to and in fluid communication with the paint applicator for mixing the single paint stream and the volume of air as they pass through the spout. A trigger is pivotally mated to the housing and is articulated between tensioned and released positions to activate the paint discharging mechanism. When the trigger is engaged, the paint is directed upwardly out of the reservoir and travels out the discharge spout to be applied to the surface intended to receive the paint.

  • Patent number: 7988067
    Abstract: A sprinkler apparatus comprises a spray tube configured to move between a first side position and a second side position. The sprinkler apparatus also comprises a first side adjustment mechanism and a second side adjustment mechanism. Each adjustment mechanism comprises markings indicating lesser to greater degrees of sprinkling coverage area. The sprinkler apparatus further comprises a coverage indicator component attached to the spray tube. The coverage indicator component includes at least one window defined therein. The first side adjustment mechanism and the second side adjustment mechanism are independently moveable in relation to the coverage indicator such that the markings on the first side adjustment mechanism and the second side adjustment mechanism are selectively viewable to the user through the window. The positioning of one of the markings within the window results in a related degree of sprinkling coverage area by the sprinkler apparatus.

  • Patent number: 7861948
    Abstract: A sprinkler includes a drive mechanism mounted in a riser that rotates a nozzle at the top of the riser. The drive mechanism enables a user to select between oscillation of the nozzle through an adjustable arc and uni-directional full circle rotation of the nozzle. The sprinkler includes an automatic arc return feature that enables the nozzle to resume oscillation between a pair of original pre-set arc limits when the nozzle is twisted by a vandal outside of the arc limits.

    Abstract: A self-powered nozzle assembly for use within a tank has a stationary body and a rotatable body rotatably connected to and in fluid communication with the stationary body. The rotatable body has an axis of rotation with at least one offset nozzle such that, as fluid is ejected from the at least one offset nozzle, the fluid applies a rotational force to the rotatable body. A rotational speed dampener is connected to the rotatable body.

  • Patent number: 7770820
    Abstract: A spray apparatus comprises a housing having a fluid inlet, a plurality of tubes for dispensing fluid from the housing, and an integrating member operatively coupled to at least a subset of the plurality of tubes for effecting coordinated movement of the coupled tubes in response to movement of the integrating member. An actuator, such as a turbine or an adjustable control ring, is employed for inducing movement of the integrating member. The dispensing tubes may be flexible so as to allow for easy adjustment of the fluid-dispensing direction or shape by the application of a lateral force at one or more locations along the length of the tubes. The flexibility also facilitates amplified direction/shape changes (compared to rigid dispensing tubes) in the dispensed fluid streams, e.g., when the tubes are subjected to a lateral force on one side and an opposing pivoting force (axially offset from the lateral force) on the other side.

  • Patent number: 7740186
    Abstract: An improved shower head having multiple modes of operation. The shower head may include a first turbine and turbine, each disposed within a unique flow channel. The first and second turbines may interrupt water flow through their respective flow channels, thereby providing at least one pulsating water spray emanating from the shower head. The shower head may include a third flow channel having no turbine disposed therein, such that water flowing through the third flow channel is not interrupted and thus emitted from the shower head as a drenching spray.

  • Patent number: 7731103
    Abstract: A dispensing system for dispensing a viscous, flowable product such, for example, as a spin-art paint solution, comprises an axially extending container that defines an opening and an interior chamber for receiving and storing the flowable product. A discharge assembly is coupled to the container, the discharge assembly being dimensioned and arranged to spin, relative to the container, as it receives the flowable product from the interior chamber. The spinning motion of the discharge assembly, which may be accompanied by a linear movement of the container itself relative to a target surface, allows the user to cleanly and evenly distribute the flowable material onto a target substrate in an attractive, curvilinear deposit pattern. Optionally, the discharge assembly may be configured with a pivoting nozzle that can be moved from a position for obtaining a helical (curvilinear) deposit pattern to a position for obtaining a rectilinear deposit pattern.
