Abstract: An improved fabricated faucet is disclosed in which no mounting screws are visible when the spout is mounted. In a preferred embodiment an under cover has a notch received on a tab within an internal surface of an upper cover to secure the two at a forward end. Screws preferably secure the two at a rearward end, which will be hidden when the spout is mounted. For longer spouts it may be preferable to use two of the notch and tab combinations spaced symmetrically about a central axis of the spout. Ribs formed on the upper cover may abut the under cover to provide additional rigidity. In another aspect of the present invention, an outlet end portion of a fluid flow line is received in an outlet port formed through the under cover. The outlet end portion has threads at an inner periphery to mount an end effector, such as an aerator or a stream straightener. A sealing ring is received at the outer periphery of the outlet end portion to provide a fluid seal between the outlet end and the under cover body.

Abstract: A pull-out lavatory is disclosed wherein a spout may be removed from a sink top to direct a stream of water to a desired location. The spout is mounted laterally offset from a lateral center of the sink top, and is firmly seated in the sink top when mounted. The spout is guided out of its seat on the sink top by rotating the spout which is moved vertically upwardly out of its mount. An arrangement prevents the spout from being rotated away from the center of the sink, since that may result in the stream of water being directed outwardly of the sink. In a further aspect of the present invention, the spout includes upper and under cover members which are snapped together and which include mating rib and notch structure to add to the stability of the spout. Also, the fluid connections within the spout housing include mounting structure that ensure they are properly aligned relative to the spout housing. The overall combination results in a pull-out lavatory that may be quickly assembled and properly aligned.

Abstract: A brush and scraper attachment for a hand-held auxiliary sprayer associated with a kitchen faucet. The brush attachment fits over the nozzle end of the sprayer while the scraper is received within the brush attachment. A seal ring seated within the fluid passageway of the brush provides a sealing engagement between the brush and sprayer to prevent back flow particularly upon attachment of the scraper. The scraper attachment includes a restricted flow passage which supplies water to the scraper blade.

Abstract: A faucet valve cartridge for a dual handle faucet which facilitates conversion between a lever-operated faucet and a knob-operated faucet utilizing identical components. The cartridge may be used to control either the hot-water supply or the cold-water supply to the faucet spout. The cartridge includes an integrally formed stop member and housing within which is rotatably disposed a valving member. The housing includes a pair of outlet ports and is open to the bottom to receive the valving member and a pair of cooperating valving plates which control fluid flow. Orientation of the valving plates within the housing controls the specific configuration of the valve cartridge. Preferably the valving plates are made of a ceramic material to reduce wear and facilitate rotation.

Abstract: A rotatable valve assembly for a faucet having an interchangable stainless steel plate which forms the interior flow passage of the valving member. The plate is secured to the valving member by depending tabs which engage reinforcement ribs formed in the valving member. The flow plate is of a one-piece stamped construction with the tabs formed coplanar with the plate and bent perpendicular to the plate prior to attachment of the flow plate. An aperture is formed in the plate which cooperates with an inlet port formed in the bottom wall of the valve body to control the water flow through the assembly.

Abstract: A diverter valve 10 has a two piece housing 22 including a lower member 24 and an upper member 26 securely snap fitted together within a cavity 12 of a faucet body 14. The housing 22 has a piston valve assembly 28 slidably mounted therein for movement between a first position which allows water to flow through a spout and a second position which allows water to flow to a spray head. The diverter valve has prongs 72 which resiliently bias the spool assembly 28 to the first position to reduce chattering of the valve assembly and to provide a back-up anti-siphon system.

Abstract: 'An aerator has a pressure responsive valve assembly therein for restricting the flow therethrough when the pressure of the water supply is increased. The aerator includes a housing mounting a stream straightener member and a partition member. The partition member seats an annular O-ring which in turn seats a movable valve element. The valve element and partition define an assembly with a variable sized passageway. The valve element is responsive to pressure from the pressure source to compress and move the O-ring to constringe the passageway. A mixing body is movably mounted between the stream straightener and the partition member for mixing water from the passageway with air. The valve element has a depending leg which is manually operable from the outlet of the housing. The leg can be pressed upwardly to lift the valve element which opens up the passageway thereby creating turbulence in the aerator.
