  • Patent number: 4833740
    Abstract: It is known to form one or more faucet mounting holes in the deck portion of a metal sink. To separate the sink deck from the underlying countertop, a gasket is inserted between the sink and countertop in alignment with the holes. This method of construction sometimes results in a skink of inadequate strength to resist bending or warping of the deck around the holes when a faucet is secured on the deck, In addition, such holes often have sharp edges, which may cut through the brass supply tubes of a faucet.

  • Patent number: 4726390
    Abstract: Disclosed is a vacuum breaker and backflow prevention device for a faucet comprising a body member having a tubular outlet portion integrally joined by a web to a tubular inlet portion of larger diameter than the outlet portion, the web having a plurality of vent holes therethrough and peripherally supporting a flexible, resilient diaphragm and overlying plate member. The plate member has an outer region provided with a plurality of through holes and a central depending shank portion extending through a central hole in the diaphragm. The tubular inlet portion has internal screw threads for attachment to a faucet outlet member whereby the plate and diaphragm are retained in the tubular inlet portion by the outlet member.

  • Patent number: 4559650
    Abstract: There is a requirement when using toilets to prevent and/or remove the accumulation of odor-causing substances from the sidewall of the toilet bowl. This can easily be accomplished with ceramic toilets where the water is directed to swirl around by angled holes formed in the flushing rim. However, in stainless steel toilets, the material is too thin to form angled holes and the water has previously simply entered a flushing rim and run vertically down the wall of the toilet. This invention is an improvement in the flushing rim portion of a stainless steel toilet which causes the water to swirl around as in ceramic toilets, to effectively clean the inside of the toilet bowl. Instead of drilled holes, the rim has upturned notches in its lower wall which cause the flushing water to spray the toilet bowl wall in an overlapping pattern. The notches also contribute to the swirling action of the water.

  • Patent number: 4493338
    Abstract: Disclosed is a removable cartridge for a fluid valve which uses a simple O-ring to seal with the housing in which the cartridge is received. The valve comprises a body member having an axial inlet opening at one end and at least one transverse outlet opening. A valve seat is secured in the inlet opening and a valve means is positioned in the body member for axial movement toward and away from the seat. The seat extends beyond the body member and has a circumferentially extending groove to receive an O-ring for providing a seal with a housing in which the cartridge is received.

  • Patent number: 4456021
    Abstract: Disclosed is an arrangement which enables highly efficient and convenient food preparation. The arrangement comprises a sink having two adjacent basins. A colander and a cutting board are arranged in one of the sinks in such a way that the cutting board is supported by the top edge of the sink while the colander is slidably supported on rails beneath the cutting board. The colander is conveniently storable beneath the cutting board but, in use, is simply slid out from beneath the cutting board whereby food chopped up on the cutting board can be scraped off into the colander for rising or draining. An overflow region may be provided in the dividing wall between the two sinks so that if one sink becomes blocked, water overflows into the second sink, and hence to the drain, rather than overflowing onto the floor.

  • Patent number: 4337790
    Abstract: Disclosed is a filter for use in a faucet of the type having a removable cartridge member receivable in an underbody member, the cartridge member carrying a cam member, at least one cam follower member and a valve member actuated by the cam follower member upon movement of the cam to control fluid communication between a spout and a source of water. The filter member is removably attached to a projection on the valve member and moves with it within a passage in the underbody member through which water flows from the source. By this means, large particles are prevented by the filter from entering the faucet. The filter comprises an inner annular member, an outer annular ring member, and a plurality of flat web connecting members extending radially between the inner and outer annular members. The inner annular member has a through hole which tapers from a first diameter to a second diameter so that the inner annular member can be forced over a head portion on the projection whereafter it is latched thereon.

  • Patent number: 4320540
    Abstract: Disclosed is a discharge drain assembly (for use in a sink) including a drain body and a plug assembly adapted to fit in the drain body which features limited rotational movement between an open and a closed position. The plug includes a stainless steel strainer with an integral hollow knob having opposed sides which are inwardly concave. The knob securely but releasably retains a slotted head portion of a spindle. The spindle has a neck portion for receiving a sealing washer and a lower body portion including three leg portions. The leg portions support the plug in the open position, restrain rotation in a first direction beyond the open position, and cam the plug to the closed position when rotated in a direction opposite said first direction. The structure substantially eliminates a "finding" problem common in prior art arrangements and provides a good seal in the closed position.
